Eclipe Plugin

[kstevens715]

I'm using the Jaspersoft Studio Elipse plugin version 1.0.4.  When I go to preview a report, 9 times out of 10 it fails with the errors shown below.  What is strange, is if I keep clicking between design view and preview view, eventually the error will stop and the preview will load correctly.  I tried to uninstall and reinstall the plugin, but that didn't work.  I'm not really sure what to try.  Has anyone else seen this?

I was using Ubuntu 11.10 when I originally posted this problem.  This weekend I installed Arch Linux and I'm getting the same exact error.  I've tried OpenJDK and Oracle Java, different builds of Eclipse and a bunch of little random things... still can't get past this error.  If I install Jaspersoft Studio standalone, everything works fine.  But it would be so much nicer to work from within Eclipse.  I'm sure it's something small.

Well, I was able to get the previewer to work 100% of the time by switching the definition of the report to use Java instead of Groovy.  I spent three days trying to fix it, and it was this simple lol.  Although, it would still be really nice to get it working using Groovy, but at this point I don't really care as I'm at least just starting out with Jasper so I don't have much work that will need to be changed at this point.
