Eclipse DTP on Ubuntu 10.4 Fails!

Question

I have a very standard setting. Ubuntu 10.4 with apt-get to install eclipse. This gave me Eclipse Version: 3.5.2. I want to use the Data Tools Platform (DTP). I used the Help | Install new software ... to install it from a repo installed using Eclipse. He installed, restarted Eclipse, configured it to work, and everything was in order. Then I just restarted my computer, and that's not it. The SQL Results window has an ugly "don't enter" icon, and it reads:

  Could not create the view: Plug-in org.eclipse.datatools.sqltools.result.ui was unable to load class org.eclipse.datatools.sqltools.result.internal.ui.view.ResultsView.

I found this error in which there are some corrections and claims for correction .. but this is for Eclipse 3.7 and I have no idea where to apply these corrections. I tried reinstalling the plugin (it worked for someone else) and that didn't help. It really worked to try a new workspace, but I'm afraid that the error will happen again when I exit, and the database configuration is a huge pain in the neck to do every time I get into Eclipse. It seems that the reason is a confused connection with Lucene.

I basically need someone to tell me how I can clean up old SQL runs from my workspace (which, apparently, does not allow Lucene to get screwed on) or how to configure the search for the Lucene I need.

Please, help. This is very frustrating.

First of all, I don’t think it is necessary to install eclipse on Ubuntu using the apt or UbuntuOne repository.

The reason Debian people use apt is because it takes care of all the dependencies. However, an eclipse has very few external dependencies: the JRE and all and many internal dependencies. This is why you have pre-packaged eclipse packages.

In addition, using apt can lead to an unwanted update of the eclipse during your installation, when you need it less.

Therefore, if you want to stay on the safe side, do not use apt, go to the eclipse download page and take the latest stable version.

Since you are using DTP, you will need the Eclipse IDE for Java EE Developers package. One that weighs 205 MB. 32 or 64 bit.

Stay away from 3.7 to the release date in early summer unless you really need something in the release candidates.

I suspect that your problem is actually due to an unsatisfied plugin dependency or a mismatch in the plugin version caused by the way you installed eclipse. And the best way to get to know IMO is to do a new installation in eclipse, not the ubuntic way.

UPDATE . I also looked at the error report you mentioned. I do not think this is relevant to your case, because the problem seems to occur in the new version of the lucene plugin, and the current version (1.9.1) applies at least to version 3.4 of eclipse.
