Mark was concerned that NetBeans IDE seemed to be missing a number of very crucial plugins or that those plugins had not been adequately advertized. Here's my attempt to rectify that situation for one specific plugin, the one for developing/deploying Java applications for the Google App Engine:
I also created an issue on the Google App Engine site for missing documentation relating to this NetBeans plugin:
Feel free to add your support for this issue above.
Now a quick overview of what the plugin entails. First, of course, you need to download, unzip, and then install the NBM files that the plugin provides:
Next, you'll find you have the complete sample that is outlined on the Google App Engine site, i.e.. a Guest Book:
Also, the Google App Engine configuration file has a special icon, file support, and a visual editor:
The Services window shows a node for the running Google App Engine, which I was able to register after downloading the Java bundle for the Google App Engine:
Whenever you create a new web application, you can specify that it should be deployed to the Google App Engine, which causes the abovementioned Google App Engine configuration file to be created for you when Finish is clicked in this wizard:
And, once your application is ready to be deployed, you can right-click it and then upload it to the Google App Engine from inside the IDE:
That's a pretty solid plugin, providing exactly the kind of Google App Engine support that I'd expect NetBeans IDE to have. The only questions are when this will be mentioned on the Google App Engine site and when the plugin will be part of a standard NetBeans IDE release.
