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?

ASKER

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

So what exactly was the problem?
Avatar of Mayank SMayank 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).

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
