Q

What's the configuration for OpenJMS from C++?

A

When configuring the runtime for use with OpenJMS, we have successfully used the configuration information below. We used OpenJMS 0.7.6 and OpenJMS 0.7.7-alpha, but this information hopefully won't change significantly between releases.

Check out the OpenJMS online documentation for more details. If you're running with the default setup, you can use the following lookup names:
 

Item Lookup name
Queue connection factory ConnectionFactory
Queue for testing queue1
Topic connection factory ConnectionFactory
Topic for testing topic1

The following sections provide example snippets for configuring the runtime for OpenJMS as a JMS provider.

Explicit

xmog_jvm_loader & loader = xmog_jvm_loader::get_jvm_loader();
 
// ------------------------------------------------------------------
// you have to add one jar file to the classpath
loader.appendToClassPath( "<FQN of openjms-0.7.6.jar>" );

// ------------------------------------------------------------------
// you have configure the JNDI setup
loader.setDashDOption( "java.naming.factory.initial",
                       "org.exolab.jms.jndi.InitialContextFactory" );
// this assumes OpenJMS default setup running on localhost
loader.setDashDOption( "java.naming.provider.url",
                       "tcp://localhost:3035" );
