All,

I encounter a ClassNotFoundException when running the an portal
application in WSAD testing portal server.  The steps are
1) Start the WSAD testing portal server
2) Logon wpsadmin
3) Go to Administration->Portlets->Manage Portlets->page shown (This
portlet is unavailable.)
4) In runtime errorlog, it shows

java.lang.ClassNotFoundException:
