There's a lengthy overview with colorful screenshots of all that is currently possible with this module. There's also a brand new tutorial on NetBeans.org, describing a work flow of how one might use the module in the IDE:
Lots of it isn't working yet, or not working correctly, or not working consistently. At the moment I'm throwing regular expressions around, thanks to Sandip as reported yesterday, on detecting whether an Action is registered in xwork.xml. If it is registered, the "Deregister from WebWork Actions" menu item (on a Java node in the Projects window) can be used to delete Actions. Currently all Actions are deleted. Ultimately, only Actions of the currently selected class will be deleted. I'm working on a similar thing for JSP pages. These will be registerable/deregisterable as Results.
Aside from this functionality, a lot of other things are possible (full source structure creation via wizard, including web.xml modification, project.properties modification, and new templates, hyperlinking, code completion of xwork.xml, etc). But a lot more is planned. Right now, though, you can already complete the New Project wizard for a web application and deploy a complete WebWork application at the end of it. No further steps for configuration, or anything else, is necessary.
If you know something about WebWork, you're welcome to join the project and I'll advise you what bits are best to work on, which parts are shakiest, etc. I've noticed that the whole module works both in 5.5 and 6.0, except for the documentation popup, which doesn't work in 6.0. Not sure what the reason for that is. Maybe something in the editor that's changed in relation to documentation popup, or more likely, something relating to how text is identified in the editor.
So, welcome to the world, https://nbwebworksupport.dev.java.net/ ! Hope your stay will be long and prosperous. Or until our forthcoming Struts 2 support swallows you up.
In other news. Did you know there's a page on NetBeans.org called Learning Java Resources? I found out about it a few days ago, although it's been around a while. It gives you a long list of articles, tutorials, trainings, and discussion threads that the Java newbie might find useful. There's also the possibility of suggesting new links to be added to the list. Check it out!
