When submitting a request to the SAS Stored Process Server and you
receive an error message in your HTML output, it may be helpful to
specify "_debug=trace" on your URL when you submit the request from your
Web browser.  For example:

   http://yourserver.com:8080/SASStoredProcess/do?_program=
   %2FSamples%2FStored+Processes%2FSample%3A+Hello+World&_debug=trace

The "_debug=trace" option will trace the execution of your Stored
Process and provide a lot of diagnostic information.  Using this option
will often provide additional error messages that are not otherwise
displayed in your Web browser.

The "_debug=env" option is also useful. It displays the SAS Stored
Process Web Application environment parameters. The output includes
information about your Java environment, your Servlet Container
environment, configuration parameters, System values and Request values.

The following "_debug" keywords are available for use when invoking the
Stored Process Server:

   FIELDS - Displays the stored process input parameters.

   TIME   - Returns the processing time for the stored process.

   DUMP   - Displays output in hexadecimal.

   LOG    - Returns the SAS log file. This is useful for diagnosing
            problems in the SAS code.

   TRACE  - Traces execution of the stored process. This is helpful
            for diagnosing the SAS Stored Process Web Application
            communication process. You can also use this option to
            see the HTTP headers that the server returns.

   LIST   - Lists known stored processes.

   ENV    - Displays the SAS Stored Process Web Application environment
            parameters

For example, you could specify: "_debug=env" or "_debug=log".

Process Server, see:

Another excellent source of information when diagnosing Stored Process
Server configuration problems is your Object Spawner's log file.  View
this log file and look for error messages.
