All<br><br>I have to that upgrading a 3.0.x JBoss rules project to a 4.0.x version is not the smoothest transition.<br><br>First, I reported that the library path is not correct but I was able to work around this issue.<br>
<br>Now, I found another feature/bug.&nbsp; When I click on RETE view, I get the following exception:<br><br>!ENTRY org.drools.eclipse 4 120 2007-07-08 17:54:09.181

<br><br><br>Do I really have to create a new Project and re-import everything over to it to get it to work properly?&nbsp; Is there no upgrade feature that automatically upgrades my project like in most other Eclipse plugins?
<br><br>Thanks!<br><br>Ron<br>
