I am using MyEclipse Enterprise Workbench v4.0 on XP Home Edition. I also have JRE/JDK 5 latest version:

java version “1.5.0_04”
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_04-b05)
Java HotSpot(TM) Client VM (build 1.5.0_04-b05, mixed mode, sharing)

Well, I have installed the Workbench plugin a couple of days ago and everything was working fine until all the sudden (after a file import), I sarted getting message windows come up with:

An internal error occurred during: “Decoration Calculation”.
jzentry ==0,jzfile=853616 …… message= invalid LOC header (bad signature)

Has anybody seen this problem?

I have redone eclipse (3.1 RC4) and installed the workbench for this version, but still when trying to create/add any files to my project these messages keep coming on.

Any help is greatly appreciated.

I’ve never seen this before. Have you tried a new workspace? Or using -clean command line argument when starting Eclipse so it rebuilds it’s plugin cache?

[abukta]

Thanks for the quick feedback!

I have not tried that. I will give it a shot tonight. Just an FYI – I have installed the same setup on 2 win2k machines (JDK/JRE 5, eclipse 3.1/workbench 4) and don’t see the same problem happening.

I will keep posted.

Actually, I did try a new workspace but as soon as I add a new Servlet, I start recieving the messages about message= invalid LOC header (bad signature). I will try to start eclipse with the clean option later today.

[Riyad Kalla]

I’m officially confused… have you tried searching bugs.eclipse.org with some of that error string to see if it is indicative of anything platform-specific?

It could be that eclipse 3.1 does not get along with jre1.5 (???). This is what I see in the logs for eclipse:

Ahh, you aren’t using Eclipse 3.1 GA, try and download and use that.

Did you ever find the solution to this. I am getting this stack trace:

If you are getting a ZIP exception my guess is the file is corrupted. If you have WinZIP or WinRAR installed, try and open the JAR it’s complaining about and run the “Test archive” function on it.

[itsjimbo]

I was getting this error to. Fixed it by
Project->Properties->Java Compiler
“Configure Workspace Settings”
Use JDK 1.6

(Also somewhere some setting for the JDK was pointing to a com.myelcipse.plugiin JDK, I just had to update the JDK for myeclipse…I can’t seem to find it though, there was a drop down box that had all of the JDK’s listed)
