RE: Tomcat+OpenJms: Naming Exception

You would only use Axis' JNDI provider if you had configured OpenJMS to use
it rather than its own embedded one.
You need to construct an InitialContext that connects to OpenJMS' JNDI
provider:
 
    Hashtable properties = new Hashtable();

    properties.put(Context.INITIAL_CONTEXT_FACTORY, 

                   "org.exolab.jms.jndi.InitialContextFactory");

    properties.put(Context.PROVIDER_URL, "tcp://localhost:3035/");



    Context context = new InitialContext(properties);

Subject: [openjms-user] Tomcat+OpenJms: Naming Exception



Hi everyone,

Could you help me to identify the cause of a JNDI naming convention pbm.
Sorry, perhaps I made a usual mistake, but I am somewhat a week-end worker
only. Where can I find a step/step explaination about openjms+tomcat but
with config files (that miss frequently).

For the approach, I presume that the connection once made from tomcat by the
factory is set with tcp://localhost:3035/, queues, topics etc. are check by
tcp://localhost:3035/ in openjms.xml.

Many thanks!

Environment: Win XP, Tomcat 5.0.28 (works fine), Axis 1.1 (works fine),
openjms-0.7.7-alpha-3 (works fine with provided samples and as a standalone
server - nothing included in tomcat)

Objective: from an axis web service (that works), send a received message to
an openjms queue

Issue: a NamingException when accessing the JNDI connection factory (see
output below)

...
