[needs-packaging] Eclipse Web Tools Platform

I'd like to second this package needs to be added if not supported. It is a major tool for Web Developers.

As an example, here is the error output for the Update Manager when trying to install WTP:

Requested operation cannot be performed because it would invalidate the current configuration. See details for more information.

I just spent an hour figuring out how to install WTP, so I'm going to post this information here to help people searching for this in the future, even if the original poster is probably not interested any more.

Of course this is not directly relevant to the bug, since this method also uses Eclipse's update mechanism instead of apt-get.

The information is from here: https://help.ubuntu.com/community/EclipseWebTools

============================================================
WTP can be installed using Eclipse's own "Software Updates" mechanism: Go to "Help -> Software Updates -> Find and Install", select the "Callisto Discovery Site" and later the "Web and J2EE development" plugin group. Click "Select required" to automatically select all the dependencies.
============================================================

That's it, WTP is installed. Just don't use the "official" WTP update site.

This method no longer works. The JDT and the Eclipse bundle shipping with Karmic is horribly broken. It is missing a buttload of plug-ins. Any attempt to use Help -> Software Updates -> Find and Install now results in the following:

If you download the Eclipse Java Development bundle directly from the Eclipse side and run it from a local directory you get a _lot_ more update sites listed, you also start out with all of the packages and plugins you are supposed to have. It's like they bundled the wrong version of Eclipse or simply left out 2/3rds of the Java development package. A person cannot run Mark Dexter's persistence tutorial with what got delivered for Eclipse with Ubuntu/KUbuntu.

Ubuntu's packaged Eclipse has no update sites as of Dec-07-09.

I can confirm this is still an issue in Ubuntu 10.04.1.

Here is the download page for the most recent release version of WTP: http://download.eclipse.org/webtools/downloads/drops/R3.2.1/R-3.2.1-20100730021206/

This page notes that the prerequisites are:

* EMF v2.6 Runtime Minimum executable code
* EMF XSD v2.6 Runtime Minimum executable code
* Graphical Editing Framework (GEF)
* Data Tools Platform (DTP) (required only for EJB or JPT development)
