"Loader not initialised!" in Visual Administration in Portal 7.0

26 Views

Hello Folks,

We are using SAP Portal 7.0 SP14. We are facing and issue on launching NWA, local SLD and User Administration etc.

The Error while launching NWA says

Application error occurred during request processing.

Details: java.lang.NoClassDefFoundError: null
Exception id: [0003BA22D0CA00750000001200002C480004E9DDE4CD591A]

We noticed that some of the application (Services) in Visual Administration are showing as "Loader not initialised!"

E.g. :

com.sap/irj

sap.com/tc~sld~wd~admin


We found this error on many Services particularly in Web Dynpro applications (Standard). Restarting the relevant application services and the server does not solve the issue.

Error in Server0 Logs show as follows.
