Error while installing SAP NetWeaver 2004s SR2

Hi,

We are installing SAP NW2004s SR2 on Linux/Oracle.

In the 18th step of "Execute Service"("Create Secure Store"), we are getting an error

<i>CJS 30050 - Cannot create the secure store. See output of log file SecureStoreCreate.log.

Exception in thread "main" - java.lang.NoClassDefFoundError: com/sap/engine/offline/OfflineToolStart</i>

Any help?

Thanks a lot in advance

regards,

Sujesh
