Bus members troubleshooting tips

Use this set of specific tips to help you troubleshoot problems with bus members.

Error 500 when adding a new member to a service integration bus.

When using the WebSphere® Application Server administrative console to add a server as a new member of a service integration bus, you can receive an Error 500 message, with the additional message "An error occurred while processing request: /ibm/console/sIBusMemberCollection.do". In addition, the SystemOut log contains a null pointer exception for the stepsLayout.jsp; for example:
[9/21/04 14:35:18:282 CDT] 00000031 ServletWrappe E   SRVE0068E: Could not invoke 
the service() method on servlet /secure/layouts/stepsLayout.jsp. Exception thrown : 
java.lang.NullPointerException
Note: This topic references one or more of the application server log files. As a recommended alternative, you can configure the server to use the High Performance Extensible Logging (HPEL) log and trace infrastructure instead of using SystemOut.log , SystemErr.log, trace.log, and activity.log files on distributed and IBM® i systems. You can also use HPEL in conjunction with your native z/OS® logging facilities. If you are using HPEL, you can access all of your log and trace information using the LogViewer command-line tool from your server profile bin directory. See the information about using HPEL to troubleshoot applications for more information on using HPEL.

This occurs in situations where your firewall product is configured to remove the private header information (Referer) from requests, because the WebSphere Application Server administrative console requires the header to contain the referer.

To solve this problem, you can either configure your firewall product to allow the private header information (Referer) in requests or disable the firewall product. For example, for information about configuring ZoneLabs to allow the referer in requests, see the Private Header Information (Referer) article at http://www.hotcomm.com/FAQ/FAQ_ZA.asp#referer.
