NamingException

[georgep]

Hi,
I'm running Tomcat separately from JBoss and am trying to access the Interest example Session Bean from a servlet client. Accessing it from the InterestClient example works fine, but I get the following error in the stack trace from a servlet exception:
"javax.naming.NamingException: Cannot create resource instance"

From the debug code I can verify that a JNDI context object is successfully generated. But the lookup method fails to generate a reference to the Interest bean, as listed:
Object ref = jndiContext.lookup("java:comp/env/ejb/Interest");

I have declared in the Tomcat deployment descriptor for my webapp the corresponding EJB references, as follows in web.xml:
<ejb-ref>
EJB reference to Interest Session Bean
<ejb-ref-name>ejb/Interest</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
org.jboss.docs.interest.InterestHome
org.jboss.docs.interest.Interest
</ejb-ref>

I would greatly appreciate any suggestions on solving this one.
Thanks,

George

P.S. Sorry if this problem has already been covered somewhere!

Hi george,

I've been trying out this combo of Tomcat 4.0
(running separately) with JBoss as well
and have found a couple of a things to check
to ensure no JNDI related problems when
accessing EJBs from servlets -

a) the servlet webapp has the
jndi.jar,jnp-client.jar,jboss-j2ee.jar
and jboss-client.jar in the WEB-INF/lib directory

b) Tomcat is started with the -nonaming option.
You can edit the startup.bat/startup.sh
in the bin directory of the installation
eg:
call "%EXECUTABLE%" start -nonaming %CMD_LINE_ARGS%

let me know if this works for you.

Gokul.
