Hi,<br />
<br />
The following exception is from an EJB2.1 application running on WebSphere 6.1 Network Install. An ejb lookup is failing. It happens to only one ejb. What could be the problem?<br />

You may want to have a look at http://www.ibm.com/developerworks/forums/thread.jspa?threadID=196528&tstart=0 to see if the root cause of your problem is similar to that one.

Thank you for the reply.<br />
<br />
I found the problem. One of the resource references in the ibm-ejb-jar-ext.xmi file was wrong.
