  2. Look for a jar called jaas.jar (unless WLS has repackaged it). This contains this class (part of the JAAS implementation). You seem to be missing this in your classpath.
  3. class path[ Go to top ]

    add jaas.jar to ur classpath. it shud work.
  4. Did that work[ Go to top ]

    The point i wanna make it clear is that is this a problem with rt.jar which is with my JDK.
  5. Did that work[ Go to top ]

    I have been using Oracle 9iAS with same error. What solve this was remove classes deployed with Applications. I don't know why, but work fine after this.

    Best regards.
