Symptom

Standalone client. You want to lookup a UserTransaction from JNDI according to the AS guide . You do it by specifying the properties for the InitialContext programmatically, like so:

         UserTransaction tx = null;
         Properties props = new Properties();
         props.setProperty(Context.INITIAL_CONTEXT_FACTORY,
               "org.jnp.interfaces.NamingContextFactory");
         props.setProperty(Context.PROVIDER_URL, "jnp://localhost:1099");
         props.setProperty(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
         InitialContext ctx = new InitialContext(props);
         tx = (UserTransaction) ctx.lookup("UserTransaction");
         tx.begin();

But the lookup does not work, instead you get a java.lang.RuntimeException: UT factory lookup failed

Explanation

The properties are not forwarded to the lookup within UserTransactionSessionFactory. For details, see http://jira.jboss.com/jira/browse/JBAS-1270

Solution

For JBoss < 4.0.2, use a jndi.properties file instead of programmatic setup of the jndi properties. For JBoss >= 4.0.2, use the org.jboss.naming.NamingContextFactory instead of org.jnp.interfaces.NamingContextFactory. This factory provides the necessary functionality for the bugfix (remembering the last Properties passed to InitialContext()), see http://wiki.jboss.org/wiki/Wiki.jsp?page=NamingContextFactory.
