Cannot process an HTTP request to servlet [Faces Servlet] in [wcb] web application

Hi All

l am working on a Wcem 3.0 with Trex with ERP and WAS 7.3.

When I logon to http://<host>:<port>/wcb/index.html url I am able to see wcbuilder_erp & wcbuilder_erp_ume application ids.

But suddenly I am getting The website cannot display the page error message when I access the above mentioned URL.

When I verify the developer log trace it showing as 500 Internal sever error issue.[EXCEPTION] java.lang.VerifyError: Bad return type

In defaultTrace.trc file it is showing as Cannot process an HTTP request to servlet [Faces Servlet] in [wcb] web application exception.
