weblogic integration studio logon problem

[Mandar Gandhe]

Hi..
I am trying to access a wli domain using the wli studio. I have many domains configured. I can access the console for all the domains hence ensuring that they are deployed properly.
But when I try to connect to them using the WLI Studio, after I try to log on the studio, I get a series of exceptions for ClassNotFound for the class files specified in wlpi-ejb.jar, wlc-wlpi-plugin.jar and ebxml-bpm-plugin.jar. All these jarfiles are in the classpath. So can anyone inform me why i am not able to access the studio.
One more interesting observation is that if I cud manage to log access any other domain (on any other server) using the studio, and then if i try to log on to my domains (logoff from the other servers and login here), then I dont get the exceptions. They occur only if I am accessing my servers directly.
Can anyone tell me what might be the problem ?
Thanks in advance
