java.lang.NoSuchMethodError

Hi.

When I deploy my webobjects project I am getting the following error  
(error at the end of the message) .
But the build was successful. I have managed to deploy this  
application successfully before in my old PC. when I  installed  
everything  on my new PC I have problems deploying the application.

I am using windows XP, Eclipse (galileo), WOlips 3.5 and Webobjects  
5.2 upgraded to 5.2.4.

When I installed webobjects 5.2  I got the following message.

The path environment variable is more 255 characters. This may  
prevent  webobjects from functioning correctly. The entire variable  
has been saved and can be registered in the register at  
'HKEY_LOCAL_MACHINESYSTEMCurentControlSetControlSessionManagerEnvironment 
'

Can this be anyway connected to the error?

Any help will be appreciated.
