title: Eclipse DTP on Ubuntu 10.4 flakes out!
body: <p>I have a very standard setup.  Ubuntu 10.4 with an <code>apt-get</code> to install eclipse.  It gave me Eclipse Version: 3.5.2.  I want to use Data Tools Platform (DTP).  I used the Help|Install New Software... dialog to install it from the repo that comes installed with Eclipse.  It installed, restarted Eclipse, got it configured to work and everything was fine.  Then, I just restarted up my computer and everything is not fine.  The SQL Results window has an ugly "do not enter" icon and it reads:</p>
  
  <pre>
  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.
  </pre>
  
  <p>I found <a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=333514" rel="nofollow">this bug</a> which has some patches and claims to have a fix..but it's for Eclipse 3.7 and I have no idea where to apply these patches.  I tried reinstalling the plugin (it worked for someone else) and that didn't help.  It actually worked to try a new workspace, but I'm afraid the error will happen again when I exit and the database configuration is a huge pain in the neck to do everytime I get into Eclipse.  It looks like the cause is a messed up link to Lucene.</p>
  
  <p>I basically need someone to tell me how I can clear old SQL runs from my workspace (which apparently prevents Lucene from screwing up) or how to set to find the correct Lucene.</p>
  
  <p>Please help.  This is very frustrating.</p>
