I am having problems starting WebSphere from within the MyEclipse Ide.

I use the same configuration that works on the MyEclipse 3.x releases. Since the first 4.0, it just stop working.

The error I get:
Error Starting WebSphere
A configuration error occurred during startup. Please verify the preference field with the prompt: java.lang.NoClassDefFoundError: de
Exception in thread "main"

Checking the "Error Log" of MyEclipse, same error as described above
!ENTRY com.genuitec.eclipse.easie.websphere 1 0 2005-11-14 16:27:44.556
!MESSAGE Error starting WebSphere: java.lang.NoClassDefFoundError: de
Exception in thread "main"

And that's all :(
It does nothing else... i check the configuration, seems all right, jdk selected is the ibm one. (not the jre like so many use to do; the jdk for sure)

Any help, will be greatefull apreciated!

What directory is your JDK installed to and what directory is WebSphere 4 installed to? I believe this issue is a "space in the path" that we should have fixed in this release...

WebSphere directory:
In: Preferences -> Java -> Installed JREs
C:\Archivos de programa\IBM\WebSphere Studio\Site Developer\v5.1\runtimes\aes_v4

Ibm JDK directory
In: Preferences -> MyEclipse -> Application Servers -> WebSphere 4
C:\Archivos de programa\IBM\WebSphere Studio\Site Developer\v5.1\runtimes\aes_v4\java

I have done a test in:
C:\WinSoft\Develop\Java\ibmjdk1.3.1 (ibmjdk 1.3.1) with C:\WinSoft\Develop\Java\aes_v4 (WAS4) same problem. :roll:

ps; Still dont understand why in MyEclipse 3.8.x (for Eclipse 3.0.x) the websphere works great.

This seems to be a bug we thought we had fixed. The temporary workaround is to make a copy of the JDK to a dir that doesn't have spaces in it, and then setup the connector with that JDK.

Ok... Problem solved... Let me tell you what happend:

I tried to copy all the websphere staff into a non spaced directory. As i told you, done a test in:

ibmjdk 1.3.1:
C:\WinSoft\Develop\Java\ibmjdk1.3.1
WAS 4:
C:\WinSoft\Develop\Java\aes_v4

Same results... also try to make a non dotted directory for the jdk, copying it into c:\ibmjdk.
All this result in the same error. I have no logging, no nothing.

If you knew what the problem use to be, and then again, you told me that was something about spaces, i notice that in "Append to library path" there was a directory with spaces there (C:\Archivos de programa...\) directing to SQLLIB from DB2.
I have been able to solve the problem by copying the data into that directory (the one of db2 with space) to another one (without spaces).

Solution: althought crappy, usefull. Love it.

Thanks, a lot!

ps: maybe you solve the bug in any other place but not there? :) maybe in the next release then!

We've got an open bug report on this and plan to have it fixed in release 4.1 in December.

at least we now know a workaround... and beleive me... i am another happy MyEclipse user.

once again, thanks for the help.
