Sounds to me like you just have the Java JRE, not the JDK installed. You might need to install the JDK and/or change the “JAVA_ROOT” variable in \bin\server.bat (for NT/Win2K, server.sh for Unix) to get this work.
I’ve had the same problem, so I’ve installed the Sun JDK 1.3.1, changed the JAVA_ROOT and rebooted the Integration Server, then it worked.
