Chapter 10. The Client Classpath

10.1. HornetQ Core Client
10.2. JMS Client
10.3. JMS Client with JNDI

HornetQ requires several jars on the Client Classpath depending on whether the client uses HornetQ Core API, JMS, and JNDI.


All the jars mentioned here can be found in the lib directory of the HornetQ distribution. Be sure you only use the jars from the correct version of the release, you must not mix and match versions of jars from different HornetQ versions. Mixing and matching different jar versions may cause subtle errors and failures to occur.

If you are using just a pure HornetQ Core client (i.e. no JMS) then you need hornetq-core-client.jar and netty.jar on your client classpath.

If the client runs inside a Java 5 virtual machine, use instead hornetq-core-client-java5.jar.

If you are using JMS on the client side, then you will also need to include hornetq-jms-client.jar and jboss-jms-api.jar.

If the client runs inside a Java 5 virtual machine, include instead hornetq-jms-client-java5.jar.

If you are looking up JMS resources from the JNDI server co-located with the HornetQ standalone server, you wil also need the jar jnp-client.jar jar on your client classpath as well as any other jars mentioned previously.
