500 Internal Server Error : java.lang.NoClassDefFoundError in XI - SLD


Hi Friends,

We have upgraded the NW2004s java sp level from SP 04 to SP 05. But after doing so we are getting the following error while accessing the System Landscape Directory from the following link


The error description is as below

"500 Internal Server Error

Web Dynpro Container/SAP J2EE Engine/6.40

Failed to process request. Please contact your system administrator.

Error Summary

While processing the current request, an exception occured which could not be handled by the application or the framework.

If the information contained on this page doesn't help you to find and correct the cause of the problem, please contact your system administrator.

Root Cause

The initial exception that caused the request to fail, was:

java.lang.NoClassDefFoundError: com/sap/lcr/pers/jdbc/CRQMappedJdbcJ2EEPoolPersistence






... 28 more

Correction Hints

It can't be determined from the exception chain, which class loader failed to load the above class. But at least the class loader of the current application does not contain a resource with name 'com/sap/lcr/pers/jdbc/CRQMappedJdbcJ2EEPoolPersistence'.

If I click on the SLD onthe SAP Netweaver - Exchange Infrastructure, I am getting the above error.

Pls help me to solve this problem.

Thanks in advance
