Unhandled event loop exception when I open a JSP file in eclipse helios

Question

I want to generate Crystal Reports in Eclipse for which I have recently downloaded crystal reports 2.0 for eclipse. I am using eclipse-jee-helios-SR2-win32 (3.6) version and Tomcat v5.5 server version.

I can generate the JSP file from the Crystal Report file(.rpt) as shown in this PDF. But the problem is when I open it. It cannot be opened by any editor except Text Editor.

On opening with other editors gives me following Error:

Message:

Unhandled event loop exception

I think I am forgetting something in installation process. Can anyone help here please Thanks in Advance !!

EDIT: Solved this error when I deleted files:

org.eclipse.jst.jsp.ui.source_1.1.601.v201108151912.jar org.eclipse.jst.jsp.ui_1.1.601.v201108151912.jar

and downloaded:

org.eclipse.jst.jsp.ui.source_1.1.401.v200908111935.jar org.eclipse.jst.jsp.ui_1.1.401.v200908111935.jar

But now I lost complete support of JSP from Eclipse. Refer this for more information.

Answer 1

Solved this error when I uninstalled following plug-ins from Help->About Eclipse SDK->Installation Details:

• Android DDMS, Android Development Tools, Android Hierarchy Viewer, Android Traceview.

• Eclipse Java EE Developer Tools

• JST Web UI,etc...

And then again Re-installed them.

Finally I got JSP support on Crystal Reports(.rpt) files as well as complete Android support on Eclipse.
