The problem is that you’re trying to launch WebSphere with a non-IBM JDK. IBM heavily modifies the JDK shipped with WebSphere and those changes are vital for proper functionality. WebSphere won’t run on a Sun JDK at all, as far as I know. Reconfiguring your WebSphere connector to use the JDK that IBM ships with the product should resolve this issue.

MyEclipse SupportDear Scott,
I launched WebSphere with the IBM JDK skipped with
WebSphere. Does not solve the problem. Also I tried to start Eclipse
with the IBM-JDK. Does also not solve the problem.Ralf,
I’ll have to dig deeper on this. Can you post the full platform information we request in the Posting Guidelines thread?
–Scott
MyEclipse SupportDear Scott,
I checked my path, classpath and removed all plugins I installed additionally. Now it works fine. Looks like a configuration problem
of my eclipse installation. Thanks for your efforts!
RalfRalf,
Good to hear you’re up and running. Thanks for the followup as I like nothing better than to close support threads. 🙂

MyEclipse SupportI get the very same stack trace in the .log file when I try to launch websphere 5 in debug mode.
Could you please tell me what changes I should make to get websphere 5 working through MyEclipse? Where do I check the path, classpath and plugins as mentioned by Ralf in the previous message? FYI, I only have Perforce plugin installed additionally.
Thanks,
Renu
Where do I check the path, classpath and plugins as mentioned by Ralf in the previous message?
I believe he was referring to the Window > Preferences > MyEclipse > App. Servers > Websphere 5 > Paths dialog.
RenuTBI,
You could try PM’ing the user you wanted to ask the question to, he will get a popup next time he visits the site.do you provide telephone support or is it just online support?
Sorry I missed that in the previous post, we currently only offer online support but I believe this is flexible depending on the number of licenses that the business has. You can email support@genuitec.com for futher details.
RenuTBI,
I checked my path, classpath and removed all plugins I installed additionally. Now it works fine. Looks like a configuration problem
of my eclipse installation.It seems that rparr123’s problem was environmental so we don’t know what he changed to correct the issue. From the looks of it, I’d suggest running Eclipse with a different JDK, perhaps 1.4.1 or IBM’s JDK, to see if the issue is an incompatibility there.
