Hi, Good Morning:

I have an application that runs in Websphere 5.1, the server in normal way starts perfectly
and the application works, but when the server tries to start in debbuger mode gives me the following exception:

java.lang.NoSuchMethodError: com/ibm/bsf/BSFManager.initBSFDebugManager()V
