Extending the NetBeans IDE Debugger (Part 2)

One way to extend the NetBeans IDE Debugger is to listen to the global context Lookup, as done in part 1 and in the recent Breakpoint Beep story. Another way is to use the extension points that you see when you extend the layer file in a NetBeans module:

For the functionality shown yesterday, i.e., barking breakpoints in the NetBeans IDE Debugger, I started by adding the following to the layer file:

<folder name="Debugger">
    <folder name="BreakpointsView">
        <folder name="Toolbar">
            <file name="org-netbeans-jpda-beep-BreakpointBeepButton-createNewBreakpointActionButton.instance">
                <attr name="serviceClass" stringvalue="java.awt.Component"/>
                <attr name="instanceOf" stringvalue="java.awt.Component"/>
                <attr intvalue="300" name="position"/>

Then I added the following, i.e., notice that the FQN of the class below (and the 'public static' are VERY important) is matched in the XML above, and then pops up a JPanel, named BeepChoicePanel. There, the DebuggerManager is used, but that's a topic for another blog entry.

Now you know how to add new JButtons to the left sidebar of the Breakpoints window in NetBeans IDE. Probably the layer file entries could be converted to a @ServiceProvider annotation, but that's also a topic for another blog entry.

GlassFish and NoAdminPortEx

The error "NoAdminPortEx" indicates, that GlassFish is not able to find the admin port for the specified domain.

The error occurs in case the domain folder ($GLASSFISH_HOME/glassfish/domains/[DOMAIN_NAME]) contains inconsistent data, often caused by an interrupted asadmin create-domain [DOMAIN_NAME] command.

Manual domain deletion (rm -rf) and recreation with asadmin create-domain [DOMAIN_NAME] solves the problem.

Barking Breakpoints in the NetBeans IDE Debugger

Especially when you have complex breakpoint definitions, such as conditional breakpoints and dependent breakpoints, your debug sessions can become difficult to understand. Why not inject some sounds into the process?

I have created a "Beep Selector" for the Breakpoints window. Notice that there's a new button in the left of the window, right below "Create new breakpoint" and "Select breakpoint groups". The icon displayed on it is what you'd expect a sound icon to look like. That button is provided by the plugin I've created. When clicked, the Beep Selector dialog opens. Predefined, you see "Dog" and "Sheep". However, anyone can drop any WAV file into the user directory, within the "Debugger/BreakpointsView/Sounds" folder, which you will need to create yourself. Any file found in that folder is automatically picked up when the dialog above reopens, no checks are done at this point, i.e., make sure it makes sense to put a file there.

Here are some great sound files:


Then any breakpoint can be mapped to any sound, either one of the predefined ones, or your own sound. And then, when the breakpoint is hit, you'll hear your sound! As stated at the start of this blog entry, this is especially handy when you have branching breakpoints, i.e., dependent or conditional breakpoints. You'll immediately be informed when one branch is taken, e.g., the 'true' condition can enable a series of breakpoints that relate to one outcome, while 'false' goes off in another direction. Assign one sound to the breakpoints in one branch and a different sound to the other branch and then your debugging will be much simpler.

And it actually works, for me. Testers welcome, please realize it is basically in Alpha state right now, though.

Get it here: http://plugins.netbeans.org/plugin/56682

Right now, to remove a sound, simply delete the breakpoint.

Ceylon for NetBeans IDE 8.0.1

The history of Ceylon support in NetBeans can be divided into three stages. In 2012, syntax coloring was created; in 2013, code completion was added; and yesterday, during Java2Days in Sofia in Bulgaria, where I ran into Ceylon lead Stephane Epardaud (@UnFroMage), i.e., in 2014, and under his guidance the Ceylon libraries in the NetBeans plugin were upgraded to the latest versions, syntax coloring was updated, the start of code folding has been implemented, and the Ceylon parser is partly integrated to check for syntax errors.

Above you see one of the Ceylon sample projects expanded to show one file, with syntax coloring, and the initial comment within a code fold.

And here you see the parser in action because a semi-colon has been omitted:

The message displayed when you hover over the red error icon or the red error mark is as follows, which comes from the Ceylon parser:

Here's the repo:

Few Women Want To Be Programmers Because Few Male Programmers Are Kind

While at Devoxx a week or so ago, the discussion about "why there are not more female programmers" was held, yet again. The abstract of the BOF that was held on this topic starts off with: "It feels like women still are strongly underrepresented in the Java ecosystem. It is even worse than in the JavaScript or Python world." Etc. And then there's the usual discussion about why this might be, about how to get more involved, how to participate in projects, about mentoring programs, about needing to have more women speakers at conferences, etc etc.

In another session, rather oddly, I learned that balloons and cupcakes are needed. At first, I looked with raised eyebrows at the guy that I was attending the session with, and we both silently mouthed something like: "Wow, there would be an OUTCRY if a male programmer were to stand on that stage and say that there need to be cupcakes and balloons in order to bring women to programming conferences." (And he'd be blacklisted from speaking ever again at any conference anywhere in the world, on any topic at all, which as far as I know has never ever happened before, making for the shortest blacklist ever.) It was, however, a female programmer on the stage (with an atypical speaker background, i.e., not from the US or EU, so some cultural differences were the basis of the perspective I believe), who also talked about a need for daycare facilities at conferences, as a precondition for more women attendees.

I've thought more about this and in my humble opinion the balloons and cupcakes theory is closer to the mark than one might think. There is a pervasive curtness and to-the-pointness and a OK-I'll-help-you-but-you-better-not-waste-my-time-by-showing-you're-an-idiotness that is more than apparent throughout the developer community, regardless of the language or the technology, i.e., in the Java community, in the Python community, in all kinds of developer communities.

Myself included! I'm often very direct and curt and might more often than not come across as being unkind, in the context of my work within various, primarily Java, developer communities. And that's simply because I want to get the job done, help out, give advice, and then move on to the next thing to work on, or to help with, or to give advice on. "Being nice", smiling, being patient, etc, are always secondary to those aims. No matter how much you, if you're a male, reading this, are now thinking to yourself: "Well, speak for yourself. I'm pretty kind and I smile a lot," I don't believe you. I believe you're hurried and when you're hacking with someone, you want to work quickly, with a lot of speed, you want to hurriedly fix one thing, and then hurry on to another thing, you want to quickly add new features, and fix bugs, and there's time pressure, all the time.

In fact, the real question is, therefore not "Why do so few women want to be programmers?" The question, the real question, is: "Why do so many men want to be programmers", given this unkind (yes, yes, you're helpful, but you're hurried, you're on the clock, no time for cupcakes, and you think balloons at conferences are ridiculous, proving my point) ecosystem?

In short, the programming world is a pretty fast paced environment, in which you need to move fast and accurately, where you tend to get looked down upon when making mistakes, code fast, and do everything else fast. The point isn't that women aren't up to those tasks, I'm sure they are. But why would they want to be? So the question is why do men not find this environment so problematic that they choose to stay far away from it? The only exception to all this that I know of is mob programming, as explained to me by the wonderful Woody Zuill, which is a very kind environment, embracing of newbies and supportive from the beginning of the day to the end:

&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;span id=&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;XinhaEditingPostion&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;/span&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt; &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;/p&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;gt;

To me, a BOF worth having on this topic should not have any women in it, as every year at Devoxx and so many other conferences. Instead, there should be a BOF aimed at men (myself included!) and about being kinder, with a title like "Towards a Friendlier Developer Community". There's something seriously wrong with men (as well as the few women who are in the various developer communities) that we tolerate the unkind, intimidating, impatient, macho attitudes that pervade the software industry, as well as so many other industries, I might add.

Java EE 7 Bootstrap Is Available ...Online

Three times a year I deliver a series of Java EE 7 / Java 8 Workshops called airhacks.com (there are some seats left for December :-)). I get more and more requests to deliver the standard set workshops in other locations, but I'm a Singleton and Singletons do not scale.

Now the Java EE 7 Bootstrap course is available online. From annotations over DI, Bean Validation, CDI, EJB to UI. 22 modules are waiting for you.

My personal goal was to keep the course as short as only possible--sometimes I re-recorded the modules multiple times to shorten them. The whole course takes 3 hours of continuous coding with a few sketches. Originally I thought about 1h, so I missed the target a bit...

Red Hat OpenShift

When you're thinking about creating a NetBeans plugin for your favorite technology, there's not much that hasn't been created already, in one way or another. For example, want to create a NetBeans plugin for your web framework? Not a problem, just look at all the open source projects, as well as the NetBeans source code, to see how tools for PrimeFaces, Wicket, Tapestry, etc etc, have been implemented. Want to create a NetBeans plugin for your favorite application server? No problem at all, just look at the code of the other application server plugins and then you can, as Emmanual Hugonnet and other guys at Red Hat have done, create a plugin for WildFly, etc.

And so Cojan van Ballegooijen and others in the Red Hat community interested in NetBeans integration for OpenShift don't need to worry, either, since there are several NetBeans plugins already for cloud providers, e.g., Oracle Cloud, Amazon Beanstalk, and Jelastic. Thanks to a bit of refactoring of the Amazon Beanstalk plugin, which is open sourced since it is part of the NetBeans sources, here's the start of the OpenShift plugin:

The basic infrastructure shown above is in place and can be found here:


It should probably be put on GitHub so that anyone can clone it and then fill in all the OpenShift-specific settings, e.g., the logic for connecting to the OpenShift services, the logic for deploying to OpenShift, and the logic for displaying the artifacts deployed to OpenShift. And all that can be based on the Amazon Beanstalk code, too.

And all thanks to open source, without which none of the above would be possible.

Bug Fixes and Enhancements for NetBeans Cheat Sheets

I fixed several problems in the Cheat Sheets plugin and added a cool new feature.

  1. Installation problem. Several people weren't able to install the plugin in the first place, or didn't see the two new windows provided by the plugin when they thought they had installed it. That's because the plugin was built with all the patches for 8.0.1 included, which meant that one of the NetBeans modules used in the plugin was at a higher level than what you'd have in 8.0.1 if you hadn't updated it, i.e., to patch 1.1. I discovered that the problematic module (the Datasystems API) wasn't needed in any case, so removed that module from the dependency list. Now the plugin should install successfully if you're using 8.0.1 without any of the patches installed.

  2. Parsing problem 1. Several people were able to install the plugin but didn't see anything in the two windows provided by the plugin. That's because the parser attempts to validate and resolve any references in the document, automatically, including "netbeans.org". When you're using the plugin while not on-line or behind a proxy, the automatic resolver fails and the plugin crashes. I was able to reproduce this problem and, following the instructions here, I fixed the problem, and now even when I am not on-line, the plugin works, because the automatic resolution is disabled.

  3. Parsing problem 2. The PHP and HTML code templates files weren't parsed correctly, so that only the left-hand side of the Code Templates window was shown, not the right-hand side. That's fixed now.

  4. Context-sensitivity enhancement. I was demonstrating the plugin during Devoxx to my ex-colleague (and current Red Hatter) Cojan van Ballegooijen (and we encountered parsing problem 1 several times), who suggested the following new feature: "Whenever a document of a certain type is opened, the Code Templates window should automatically switch to the relevant set of code templates." That's a cool idea and thanks to the Lookup (i.e., in the TopComponent, listen to the Lookup for the current FileObject in the global context, check for its MIME type, and then switch the code templates accordingly).

Below you can see the point, i.e., now an HTML file is open and hence automatically the Code Templates window shows the code templates specific to HTML files.

From the above, you can also see that the plugin hasn't only been tried successfully on Windows, but on Ubuntu too.

Right now, code templates for PHP, HTML, Java, and XML are supported. A next feature could be support for more code template files, as well as an automatic update of the windows when the key bindings or code templates are changed in the Options window, because right now any changes you make will not be reflected, whether you restart or not. That's because changes to the settings shown above are done in different files to the ones that the plugin listens to, at the moment. So the next enhancement will be to listen to changes to the file where changes to these settings are stored.

If you'd like to try out these changes, go to the plugin's location in the Plugin Portal below, download the NBM, install it into NetBeans IDE 8.0.1 (you should notice in the Plugin Manager that the version of the plugin is 4.0), and then (after a moment, while the plugin installs) you should see your new windows appear, which are also openable under the Window menu, where you should see "Code Templates" and "Key Bindings" menu items.

Obrigado Spellchecker for NetBeans IDE

Let's set up Portuguese spellchecking in NetBeans IDE. The aim is to see words like this, i.e., Portuguese words, instead of English words:

In the Options window, I registered a "pt_PT" spellchecker, as shown below:

To be able to register the above spellchecker, I clicked Add above and then used the Add Dictionary dialog, shown below:

The "aspell_dump_pt_PT.txt" file that you see above was created on the command line.

aspell --lang=pt_PT --master=pt_PT dump master | sort > aspell_dump_pt_PT.txt

The above assumes that Aspell has been installed and that the "pt_PT" Aspell dictionary has been installed.

To achieve the above, i.e., to set up Aspell and its Portuguese dictionary, simply follow step 1 of the document below:


The majority of the document above discusses how to create a NetBeans module that bundles the Portuguese dictionary. I think it can be done more simply than is described above and will make a blog entry about that. However, you now have enough information to at least make a dictionary file and register it into your own NetBeans IDE installation.

Tools for MVC in Java EE 8 (Part 2)

What's happened since part 1 of the blog series on tools for MVC in Java EE 8? Well, I sat down quite a bit with Manfred Riem, one of the spec leads for MVC in Java EE 8, during Devoxx.

One of the outcomes is the below (click to enlarge the image), i.e., a logical view (comparable to NetBeans IDE support for RESTful Web Services) for the methods in the controlers of MVC applications:

Above, you see the project logical view has a new node named "MVC Methods", containing all Java classes that have at least one @RequestMapping annotation, which can be expanded to show each of those methods. When new methods are added to the editor, or removed from it, the logical view is automatically updated. Double-click on a node and the Java class is opened with the applicable method highlighted.

Similar to the RESTful Web Services logical view, the above enables you to very quickly see the entry points into the application which will, eventually once those things are figured our more, enable them to be tested, similar to RESTful Web Service methods.

Integrated Cheat Sheets for NetBeans IDE 8.0.1

NetBeans user Sarel van der Merwe from Total Index in South Africa wants me to add new features to the NetBeans Cheat Sheet plugin. I found I'd lost the sources so recreated the plugin today, it looks as follows, i.e., it embeds a window to the right of the editor where your keyboard shortcuts and Java code templates are listed as a handy reference:

I've provided an updated plugin hopefully with more or less the same functionality to everyone's liking:


Install it into NetBeans IDE 8.0.1, probably won't install in earlier releases. I've found it to be a pretty handy tool.

For further enhancements, the source code is now publicly available here:

Using Jackson in TomEE As JAXB-JSON Provider

Jackson is fast JSON processor with nice default behavior, e.g. single element collections are represented as JSON arrays, and there are no wrapping elements.

Because the default is already reasonable, there is no additional configuration needed. The provider can be specified directly in the /src/main/webapp/WEB-INF/openejb-jar.xml descriptor:

<openejb-jar xmlns="http://www.openejb.org/openejb-jar/1.1" 
    <pojo-deployment  class-name="jaxrs-application">
            cxf.jaxrs.providers = com.fasterxml.jackson.jaxrs.json.JacksonJaxbJsonProvider

In addition the jackson dependency needs to be declared in the pom.xml:


A better solution would be to install jackson directly on the server (/apache-tomee-plus-1.7.1/lib), what would keep your WAR skinny.

J-Fall 2014: Bert's Big Shoes

I attended J-Fall 2014 last week, the annual Dutch JUG conference. It was without a doubt the most crowded conference I have yet attended! 1,200 attendees in a conference center in Nijkerk that is increasingly showing its limitations. But it was a lot of fun, of course.

Bert Ertman, Java champion, and frequent speaker at big international conferences, who has led the Dutch JUG over the past 10 years, announced the end of his tenure as JUG leader. He'll be missed! Bert has really been 'the face of the Dutch Java community'. Big shoes to fill, whoever ends up filling them.

I met several people who I've come to know over several years, as well as several people I met for the first time, some who I've known for years via e-mail and so on. From this place, a big shout out to Remko de Jong, Martijn Dashorst, Hubert Klein Ikkink, and several others.

I really enjoyed the ING keynote by Peter Jacobs (ex Sun!) a lot. Rather than yet another marketing speech by the key sponsor of a conference, which always bores the hell out of any developer from the 2nd minute onwards, Peter Jacobs discussed the internal IT/software technology choices that have been made at ING over the past years. Continuous builds, agile, AngularJS, Cassandra, Docker, etc. All the cool methodologies and technologies of today, embedded deeply within ING, i.e., a bank! Not what I had expected from a bank. Their IT/software stack sounds really cool and their innovation and openness to new ideas too.

The Oracle keynote reminded me of Sun keynotes in days of old. The focus was on community activities that, in the past, Roger Brinkley would present. In the present, Oracle's Jim Weaver, JavaFX 3D evangelist, is the driving force. In particular, Timon and Eva's open source precision agriculture project AgroSense that won a Duke's Choice Award last year was highlighted:

Another big focus in the Oracle keynote was the open source Raspberry Pi framework PiDome by John and Marcel, which won a Duke's Choice Award this year:

Other sessions I attended were about Wicket (going strong while being 'feature complete'), Java EE 8 (by my colleague David Delabassee), JSF migration to SPA (Matthijs Aalbregt & Eelco van Dijk), performance of Java 8 (Jeroen Borgers), and Aciidoctor (Hubert Klein Ikkink, the fastest talking Dutch guy, in the world).

My key takeaway from the packed out JSF/SPA session is that, wow, you're pretty screwed if you want to do serious work with JavaScript. There are simply so many frameworks (I learned about sammy.js, which was great, for once the key JavaScript framework was NOT angular.js, simply for that change of scene I was grateful) that there's nothing that anyone has in common anymore. In the past, when a demo failed in a session at a conference, everyone would be able to jump in and help, i.e., there'd be a lot of people amongst the attendees who'd know enough about Java EE or Spring to jump in and say 'hey, your injection should have been like this or that'.

But what happens when you have a new JavaScript framework popping up every week and the speaker has chosen 5 of them and combined them somehow and then the demo fails? Who is able to help? Who is able to say 'hey, you should have done this on line 27'? I left J-Fall interested in learning about sammy.js while wondering what the next sammy.js would be and whether it is worth learning about sammy.js since more than likely there'll be a non-backward compatible sammy.js 2.0 two weeks from now, without a migration path.

Configuring The JSON Default Provider (jettison) in TomEE

TomEE comes with Jettison and cxf as standard JAXB and JAX-RS providers. Jettison is "chatty" and might require some tweaking.

To tweak Jettison in a WAR deployment, you will have to provide two configuration files:

The first src/main/webapp/WEB-INF/resources.xml configures the JSON provider:

<?xml version="1.0"?>
    <Service id="jsonProvider" class-name="org.apache.cxf.jaxrs.provider.json.JSONProvider">
        supportUnwrapped = true

In the /src/main/webapp/WEB-INF/openejb-jar.xml descriptor, you only have to refer to the earlier defined configuration:

<openejb-jar xmlns="http://www.openejb.org/openejb-jar/1.1" 
    <pojo-deployment  class-name="jaxrs-application">
            cxf.jaxrs.providers = jsonProvider

TomEE greatly simplifies the configuration--checkout the CXF standalone example as reference / comparison.

NetBeans Day in Germany: 2 December, 2014

During NetBeans Day 2014 in San Francisco, mention was made of more NetBeans Days being planned over the coming months. Right now, plans are in the works for NetBeans Day Germany (December 2014), NetBeans Day South Africa (January 2015), and NetBeans Day Netherlands (February 2015).

The first of these you can already register for on the Eppleton site:

As you can see above, 2 December is the date!

There will be as few slides as possible and as much code as possible throughout the event!

Sign up on the form, which is available after clicking here!

If you can't make it this time (it's only a month away), don't worry too much, there'll be more NetBeans Days in Germany during next year. The great thing is we have arranged for Oracle to host the day, which makes a big difference in terms of logistics.

Following NetBeans Day, you can attend a NetBeans Platform course hosted by Toni Epple, the details for which are here. I cannot recommend Toni's course highly enough, he has an incredible wealth of experience, and if you want to learn how to leverage the NetBeans APIs as the basis of your own software, it would be brilliant if you'd first attend the free NetBeans Day and then spend the next three days with Toni, learning about the architecture underpinning software at NATO, Boeing, NASA, and many others.
