Re: [JBoss-user] Problems accessing an ejb from a servlet.
Hi all,
I have copied all the .jar files for the
$JBOSS_HOME/client to the lib folder of the
tomcat-3.2.2 context serving the client ejb servlet.
Now where I am I going wrong.
Thank you in advance.

Re: [JBoss-user] Problems accessing an ejb from a servlet.
I am reposting this question after unsuccessful
debugging. I have learnt one thing though, the line
"Got Context" is been executed then the exception gets
thrown as I never get to see the line "Got reference".
I think the problem could be in the way I have set the
environmental variables.
Thanks in advance

I'm not certain this will make a difference here, but I believe the jar files needed by the application have to be stored in the WEB-INF/lib directory, not the $TOMCAT_HOME/lib directory. -- === David M.
