Doew anyone know th Initial Context properties for JMS?

[Ken Baltrinic]

I am trying to get the following code to work from a session bean running on
AppServer8. When I call new InitialContext(), the context I get pack has no
properties. This leads me to suspect that i need a jndi.properties file
with the correct settings. I suspect the settings I need are
java.naming.factory.initial and java.naming.provider.url but I don't know
what to set them to. I am also not sure exactly where to put the properties
file or how to tell the AppServer where to find it. Can anyone help?

Thanks in Advance,
Ken

This is what I cant get to work:

Context ctx = new InitialContext(prop);

//THe above line runs but contains an empty context.
//consequently the following fails.

TopicConnectionFactory topicConnectionFactory;
topicConnectionFactory = (TopicConnectionFactory) ctx.lookup(
"jms/log4jConnectionFactory");

It's specific to the app server; you'll have to dig into the
documentation to locate the definitive specification. I've
used code like this in the past:

Context context = null;
Properties props = new Properties();

try {
// for BEA WebLogic
props.put( Context.PROVIDER_URL,
"t3://hostname:7001" );
props.put( Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory" );
// for IBM WebSphere
props.put( Context.PROVIDER_URL,
"iiop://hostname" );
props.put( Context.INITIAL_CONTEXT_FACTORY,
"com.ibm.websphere.naming.WsnInitialContextFactory" );
// for both
context = new InitialContext( props );
}
catch( NamingException e ) {
...
}

I don't run AppServer8 so I don't know that this is going to be of
any use whatsoever... :-(

As Sudsy already pointed out, this depends on the application server
you're using. For Resin and Tomcat for example, no properties are needed.

Some examples:

Resin:
Context context = new InitialContext();
// Option 1
DataSource dataSource1 = (DataSource)context.lookup("jdbc/datasource");
// Option 2
DataSource dataSource2 = (DataSource)context.lookup("java:comp/env/jdbc/datasource");

Tomcat:
Context initialContext = new InitialContext();
// Option 1
Context context = (Context)initialContext.lookup("java:comp/env");
DataSource dataSource = (DataSource)context.lookup("jdbc/datasource");
// Option 2
DataSource dataSource2 = (DataSource)initialContext.lookup("java:comp/env/jdbc/datasource");
