Again I write about one of what seems to be my favorite subjects. Binding in Java has, over the years, occupied a bit of time for many Java developers (not that binding is unique to Java). I am thankful for this time because it has ultimately made using really easy.

Despite the busy holiday season now among us (Thanksgiving and Christmas for my family and me) along with the usual stuff, I wanted to write something quickly about NetBeans, specifically about version 6.5 since it was released not that long ago and has something relatively minor but very nice included.

I have, in the post, posted a hack we employ to get JAX-WS to generate property listeners/notifiers in the generated POJOs we rely on for binding (we're using JSR-295).

The NetBeans team resolved an outstanding issue that makes this a good bit easier (although in my opinion it should be default JAX-WS behaviour). Assuming JAX-WS does not yet generate property event notifiers (and last time I checked it did not), you need to add some import options to your web service in NetBeans. If you care to, you can utilize or modify one of the injectors which were written for JAX-WS. In order to use the one I have posted here, follow these steps from within NetBeans (6.5).

  • First import the web service client (as usual) by (right/ctrl) clicking on the project name and selecting "Web Service Client..."
  • Next enter the URL of the WSDL and click Finish
  • Now take advantage of the new options in 6.5 by right (or ctrl) clicking on the name of the newly-created web service client reference and select "Edit Web Service Attributes"
  • Now go to the Wsimport Options tab (which is pictured in the attached image)
  • You'll want to add three items to the Jaxb (xjc) options. These are the three "Option/Value" pairs:
  • Option: value; Value: -cp (this sets the classpath)
  • Option: file; Value: /opt/jaxb2-commons/lib/property-listener-injector-1.1-mod.jar (this is the fully-qualifed file name of where I put the injector on my system)
  • Option: value; Value: -Xinject-listener-code
I hope this helps someone out there who might read this but keep in mind, it is all subject to change. We've been following/using NetBeans and binding for a while and things have progressed nicely overall and we have no reason to suspect this won't continue.

Happy Hacking,
Carl

ClassCastException: JAXB

Image
A particular Java application I co-developed leverages both SOAP/WSDL and REST web services.  We use maven to manage the build process of this application which has been in production for a few years now.  It's been around long enough to have moved from Java 5 to Java 6 and now Java 7 (with limited testing using Java 8).  We have also had the experience of initially including JAXB jar files with our application and dealing with the "endorsed" directory because JAXB versions were a bit of a moving target for a while. Now that JAXB is neatly included with Java as it should be so we no longer include it.  I thought all of this was behind us (and unfortunately somewhat forgotten) until recently when we added Jersey 1.17 to the application to call some newer REST services. When trying to connect to the server, my stack trace included this: Caused by: java.lang.ClassCastException: com.sun.xml.bind.v2.runtime.JAXBContextImpl cannot be cast to com.sun.xml.internal.bind.api

Minishift on HyperV

Image
Although I would not consider myself as a heavy user of Windows, I believe I need to try to meet the challenge of supporting those running Linux, MacOS, and Windows. I recently ran into an issue running Minishift on Windows 10 and Hyper-V.  I suspect regular users of both of these technologies might already be aware of what tripped me up but I thought I would document it here just in case someone needs it.  In case you're not aware of it, Minishift is a very nice project that allows a developer to easily run OpenShift , also known as OCP or OpenShift Container Platform, on a desktop computer. Overall, I had a nice experience installing Minishift on a Windows 10 computer running HyperV but once I stopped and restarted Minishift, and had a new ip address address assigned to the VM, the instance would no longer start.   Now if you're doing any Docker development on your computer and you move around a good bit or perhaps you're on and off a VPN, you probably know that v

Parallel to Lincoln's angry letters never sent concept...

With all that I read, hear, and see these days about folks (not excluding yours truly) expressing themselves, I sometimes wonder about President Lincoln's idea of writing but not sending letters .  For better or worse, there is certainly a sharp contrast between that and typical use of today's communication. I was not necessarily thinking of opinions, emotions, and perspectives although I do see the wisdom in the Lincoln's method of dealing with such issues. My issue, at least this time, was being stuck with a particular problem using a technology which is not part of my regularly used skillset.  The technology itself is irrelevant to my point so I won't name it here. I had struggled with a solution after a bit of reading the documentation, searching for and modifying some similar examples, and experimentation.  The time I had put in was actually very little because I was simultaneously working on other parts of the solution.  That's another way of saying I wa
