Hi,

I upgrade to the latest version of MyEclipse (3.8.3) and have notice a boat load of warnings in the following format that were not present prior version. Here is one of the warnings that I am gettings

Severity Description Resource In Folder Location Creation Time
1 IWAE0010E Run-time exception java.lang.NoClassDefFoundError occurred during validation. The validator being run was JSP Validator and the message thrown was . workbench December 17, 2004 8:33:11 AM

I am sure that it is somewhere on some website, but what is warning IWAE0010E? I think that I remember that back 2 or 3 versions of MyEclipse, I had a similar problem. And, of course, they all go away when I disable JSP validation. Any ideas?

Thank you for the help,

James

James,

I am sure that it is somewhere on some website, but what is warning IWAE0010E?

It’s a vestigal code that we intended to remove in release 3.8.1. I’ve found and stomped out the last of them now, thanks to this post. You can ignore the code and simply pay attention to the message itself, which was the NoClasDefFoundError you posted here (you can ignore the partitioner exception above it):

This exception is the real problem that is being reported and is often indicitive of an installation problem. Can you try restarting your workspace with the -clean commandline option (eclipse.exe -clean …) and then forcing a rebuild on the affected project to see if that resolves the issue?

Are you recommending that I re-install everything – Eclipse, MyEclipse, other plug-ins? Or just MyEclipse?

THanks,
James

James,

Actually, I’m just recommending that you start with the -clean option and rebuild a project. 🙂

If that doesn’t work and you want to try a reinstall, I’d suggest using a fresh copy of Eclipse and MyEclipse installed in parallel to your existing installation. This isolates both environments and allows a side by side test on the same workspace. If the new install doesn’t resolve the issue, then it can be easily deleted. By the way, the other reason I think this is an installation issue is this:

I upgrade to the latest version of MyEclipse (3.8.3) and have notice a boat load of warnings in the following format that were not present prior version.

We didn’t make any changes to validation in this release.

[James I. Falek]

Once again the MyEclipse support team has come through! Y’all are great! I did a -clean start and all is well. Thank you very much!

James

[Scott Anderson]

Glad to hear it.
