[7/20/05 15:36:28:884 CDT] 5b0e2c WsServer E WSVR0009E: Error occurred during startup
 
Cause
Corrupted ibmjsse.jar file under /WAS_HOME/java/jre/lib/ext directory.
 
Solution
By looking at the exception , startup failed with java.lang.ClassFormatError for the class com/ibm/sslite/e (Truncated class file).

Figure out which WebSphere jar file has this class file. Examine this jar file using either winzip tool (or) using "jar -xf ibmjsse.jar " command. If it fails with error message during opening then customer should replace this jar file. They can copy this file from if they have another similar install or IBM Websphere Support can send one for the version of Websphere that is being used.
