UnsupportedOperationException from FastNamingProperties when lookup a queue from inside a web app running in tomcat 6

[fmtjboss]

HornetQ 2.1.2 is running in standalonemode with JNDI.

When I try to lookup a queue from inside a standalone app, everything is ok.
But when it is done from inside a web app (running in tomcat 6), I get this exception :

Here is the list of the jar I use from hornetq-2.1.2.Final:
hornetq-core-client
hornetq-jms-client
hornetq-logging
jboss-jms-api
jnp-client
netty

Do you have any clue why I get this exception and how I can resolve it ?
Thanks for your help ?

This is not a hornetQ issue, but I will answer it since I know the anser:

go to a jboss-app-server root dir and type this:

find . -name \*jar -exec unzip -l {} \; > list.txt

You will see that FastNamingProperties is not listed on jnp-client (only on jnp-server).

And your tomcat probably has a different version somewhere of the classpath.

I would suggest you to add another jar that contains the class at your web-inf/classpath (and have all the classes available from there)...

Or maybe don't use JNDI if everything fails.

Also, you should probably be reusing the JNDI references and not getting a reference every time you send message. Your system won't scale if you do a JNDI lookoup at each message.

Thanks a lot, that was a jndi problem with Tomcat.
