APAR status

• Closed as program error.

Error description

• A "generic" java.lang.NullPointerException message is recorded
  during a failed regeneration of the HTTP plug-in.  This type of
  exception is usually a result of a bad WebSphere Configuration
  and not a problem with the HTTP plugin or the regeneration
  scripts.
  However, the message is not "specific" enough
  in determining what is wrong with the WebSphere Configuration.
  .
  nPLGC0033E: Runtime exception caught while generating plugin
  configuration:
  null
  java.lang.NullPointerException
  at com.ibm.websphere.plugincfg.generator.ConfigurationParser.
  setServerData(ConfigurationParser.java:900)
  .
  More "descriptive" messages are needed during the regeneration
  of the HTTP plug-in to help identify root cause.

Problem summary

• ****************************************************************
  * USERS AFFECTED: IBM WebSphere Application Server users       *
  *                 generating plugin-cfg.xml and making         *
  *                 requests and responses who are               *
  *                 experiencing problems                        *

  * PROBLEM DESCRIPTION: Enhanced the logging for generation of  *
  *                      plugin-cfg.xml and logging of error     *
  *                      messages shown for requests and         *
  *                      responses                               *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When plugin is generating it's config file there are certian
  places where it could crash and just show a null pointer
  exception, or something similar that doesn't give much
  information.
  
  During a request and response there are a few error
  conditions that could be logged that just show a number
  in the logs.
  

Problem conclusion

• We added many new logging statements to ConfiguratoinParser,
  which controls the plugin-cfg.xml generation. It will still
  display the error message that occured, but when tracing is
  enabled it will show a more robust set of messages that
  will allow for easier pinpointing where the exact problem is.
  
  The error logging for requests and responses was enhanced.
  Now the messages that previously just had a number now
  display what the error condition was along with the line in
  the code(lib_htresponse.c and lib_htrequest.c) where the
  problem occured.
  
  This fix is targeted for fix packs 6.1.0.15, 6.0.2.27,
  and 5.1.1.18
