1943282 - NWA is not accessible (500 internal server error) due to missing "sap.com~tc~lm~itsam~co~ui~nwa~localnavigation~wd.jar" jar file


  • When you access to NWA it failed to open but given with a 500 internal server error on the browser page.
  • However, other application links just work fine like: /irj/portal, /useradmin etc.
  • Chiefly, this issue always happens after a abnormal system migration using a non-standard SAP system migration process.
  • In the latest defaulltrace.trc you are able to find below exception:
