hello,
i'm up to develop an eclipse plugin that acts as a subscriber to a jms
server.
now i'm having problems creating the javax.naming.InitialContext i need to
create the connection to my openjms server.
here's the code:
public void init(IViewSite site) throws PartInitException {
super.init(site);
msg = "jms view";
try {
Properties props = new Properties();
props.put(Context.PROVIDER_URL, "rmi://192.168.168.12:1099/JndiServer");
props.put(Context.INITIAL_CONTEXT_FACTORY,
"org.exolab.jms.jndi.rmi.RmiJndiInitialContextFactory");
System.out.println("env is redy...");
Context context = new InitialContext(props);
System.out.println("initialcontext: " + context);
tcf = (TopicConnectionFactory)context.lookup(FACTORY);
tconnection = tcf.createTopicConnection();
tsession = tconnection.createTopicSession(false,
Session.AUTO_ACKNOWLEDGE);
Topic topic = (Topic)context.lookup(TOPIC);
tsubscriber = tsession.createSubscriber(topic);
tsubscriber.setMessageListener(this);
tconnection.start();
} catch (Exception e) {
e.printStackTrace();
throw new PartInitException("jms not inited", e);
}
}
i get the following stacktrace below
can anyone help me with that. the code works if i run it outside of the
plugin.
i tryed including the jars containing the
org.exolab.jms.jndi.rmi.RmiJndiInitialContextFactory class with the plugin
(i put a <library id='openjms-rmi-0.7.3.1.jar' /> inside the <runtime> tag.
this jar contains the org.exolab.jms.jndi.rmi.RmiJndiInitialContextFactory
class but it didn't help finally i also put all the other
openjms jar includeing the exolabcore.jar but did not help ether.
the stacktrace:
javax.naming.NoInitialContextException: Cannot instantiate class:
org.exolab.jms.jndi.rmi.RmiJndiInitialContextFactory. Root exception is
java.lang.ClassNotFoundException:
