    To me, problem looks like something is wrong with AuthenticationFilter.

    are you working on AuthenticationFilter?

    after configuring filter you started getting this error, right?

    thanks..

    Hi Neeraj,

    We are not doing anything on authentication filters.
    We have restarted the servers, after that we are not getting the portal login page.

    Thanks for your response.

  4. Re: Exception while loading Portal login page, Ver 6.1

    ClassCastException seems to indicate class loading or missing jar files. You may want to check the classpath and jar files. Comparing this system to a working one might provide some clues.

    Hi,

    We have checked the environment it has all the jars, the jar which contained the class *com.ibm.wps.auth.extensions.impl.ExtendedAuthenti cationServiceImpl* is also present in the shared libraries. And cross checked with the working environament all the jars are present. still we are unaware what is the cause. May be it is somthing to do with the filters. Please help us to resolve the issue.

    Thanks and Regards

    Rule of thumb, if your thread is not answered in 3-4 days, it's probably time for you to open a PMR.
