java.lang.ClassCastException: javax.naming.Reference thrown whilst doing a look up

We are trying to connect to a mq queue

QueueConnectionFactory factory = (QueueConnectionFactory) context.lookup(jndiRef)

but we are getting the exception

java.lang.ClassCastException: javax.naming.Reference

Is this something to do with the Connection Factory not being created correctly

Object o = context.lookup(jndiRef)

System.out.println(o.getClass());

BTW, why are you looking up for a factory? You should probably be using:

QueueConnection obj = ( QueueConnection ) context.lookup ( jndiRef ) ;

Or is this for creating some stand-alone client to Websphere MQ JMS?

the class it returns is javax.naming.Reference , could this be a classpath issue?

So what exactly was the problem?

Mayank S

I guess the class-path.

I'm pretty sure it was, but for the benefit of others with same problem reading this post it should be stated (especially when you accept every suggestion mentioned).

Agreed.
