If you have a remote configuration of SAS/STAT Power and Sample Size
in place without SAS/IntrNet licensed, the following error message
might appear in your Web browser:

   HTTP Status 500 -

   type Exception report

   message

   description The server encountered an internal error () that
   prevented it from fulfilling this request.

   exception

   java.lang.IllegalStateException: Cannot forward after response has
   been committed

Other error messages might appear. Check the Application events in Event
Viewer on the machine where SAS is installed for a Warning message that
references a log file. The resulting log file states the following:

   ERROR: The SAS/IntrNet product with which the procedure is associated
          is either not licensed for your system or the product license
          has expired. Please contact your SAS installation
          representative.

SAS/STAT Power and Sample Size in a remote configuration includes the
same requirements as for a local configuration

   * SAS/STAT 9.1
   * SAS/GRAPH 9.1

and must also have the following:

   * SAS/IntrNet (has to be licensed only)
   * SAS/CONNECT 9.1
   * Server side updates

The solution is to apply an updated license that includes SAS/IntrNet.
The product does not have to be installed, only licensed.
