– Message Body ——————————-
Hello,
always, when I do a rebuild of my WebApp I get the following warning in the Problems-View:
Run-time exception java.lang.NoClassDefFoundError occurred during validation. The Validator being run was JSP Validator and the message thrown was .
There is no filename given, only the name of my WebApp.

It seems to be JSP related, because, when I have deleted all JSPs or disable JSP-Validation, no warning appears.

Any suggestions ???

Bernhard,
If you open up a console window and simply type “javac” do you get a usage message or a “command not found” error?

Also, please try shutting down MyEclipse, erasing your .log file, restarting MyEclipse, then rebuilding your project. Then open your new .log file and copy and paste the entire contents here for us to see.

When I start javac, the program is found and prints it usage information.

I hope this information helps.

How big is your web app, would you be able to send it to us for testing? If you can, please zip it up and email it to support@genuitec.com ATTN Riyad, with a link to this forum topic so I know why I’m getting the attachment.

sanpraka,
I’m willing to bet my life that the problem is RedHat/Fedora ship GCJ/Classpath as their default Java implementation which is not a fully compatible JDK implementation. In order for Eclipse and MyEclipse to function properly you should download and install the SUn JDK for Linux. Then specify using the -vm command line argument to Eclipse which Java executable it should use, something like:
eclipse -vm /usr/local/sun-jdk-1.5.0_06/bin/java
