 Downloadable files
 
Abstract
When security is enabled, the performance monitoring servlet fails with a null pointer exception or NoClassDefFoundError. Without security enabled, the servlet works correctly.
 
Download Description
IBM® WebSphere® Application Server V5.0 ships with a Performance Servlet, perfServletApp.ear. Invoking the servlet with global security and Java™ 2 security enabled causes a large error stack to appear in the browser:


Error Message: com/ibm/ws/ffdc/FFDCFilter
Error Code: 500
Target Servlet: null
Error Stack:
java.lang.NoClassDefFoundError: com/ibm/ws/ffdc/FFDCFilter
at
com.ibm.ws.pmi.perfServlet.PerformanceServlet.refreshConfig

An error stack also appears in the browser when global security is enabled and java 2 security is disabled:

Error Message: Server caught unhandled exception from servlet [perfservlet]: null
Error Code: 500
Target Servlet: perfservlet
Error Stack:
java.lang.NullPointerException
     at com.ibm.ws.pmi.perfServlet.PerformanceServlet.doGet(PerformanceServlet.java:218)
     at javax.servlet.http.HttpServlet.service(HttpServlet.java:740)
