activebpel - installed but error message (NoClassDefFound)

[mr.knowledge]

Hi,

now I solved the problem and install.bat from active-bpel works successful. But 
if I try to run http://localhost:8080/BpelAdmin/ I get the following error 
message:

my current installation is: tomcat 5.5, activebpel 4.0, JAVA_HOME and 
CATALINE_HOME also exists...

description The server encountered an internal error () that prevented it from 
fulfilling this request.

exception
