500 internal server error for WebDynpro application

[Former Member]

Hi,

I am working on ESS MSS and having couple of custom WD Java apps along with sap delivered standard apps. Custom apps are having road map steps with edit, review & confirm steps and initial screen is loading perfectly with data but when I click on edit button getting 500 Internal Server Error - The Web Dynpro application 'application name' has expired. Restart the application . Choose 'Refresh' in the iView tray or user the browser 'Refresh' button to restart the ivew.

Other hand all standard apps are working fine and came to know that kernel upgrade we happened recently. Log showing up -

application [webdynpro/dispatcher] Processing HTTP request to servlet [dispatcher] finished with error. The error is: com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to redirect response to URL ../../drls.com/ess~workinfo/MyContactApp.
