ClassNotFound error in HttpServletRequest.

Question

          I am using Weblogic 5.1.
          Our application is basically Servlets based .
          We are setting up a cluster with weblogic(as App Server) on NT and Apache (as
          Web Server) on Solaris.
          All the setup was done as per the documentation.
          But after the Cluster Setup, the application runs fine when there is only one
          primary weblogic server , but when any of the other weblogic servers are added
          into the cluster, the application fails with ClassNotFound error in HttpServletRequest.
          the following is the Error
          Sun May 06 15:51:11 GMT+05:30 2001:<E> <Kernel> ExecuteRequest failed.

Answer 1

          The javax.* classes are in weblogicaux.jar.
          You do not have weblogicaux.jar in your classpath.
