JNDI/JBOSS

[Carlos A. Perez]

Hi everyone:

im triying to connect to JNDI from a standalone app, i start sucessfully JBOSS and use the environment properties as indicated in JBOSS doc but it sends an javax.naming.NoInitialContextException

I dont know why it sends the exception, is it something about security in jboss (this is not an EJB) or the parameters are wrong in the JBoss doc?

this is the code:

public class ConnectJNDI {

public static void main (String[] args) {
Hashtable env = new Hashtable ();
env.put (Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.NamingContextFactory");
env.put (Context.PROVIDER_URL, "jnp://localhost:1099");
env.put (Context.URL_PKG_PREFIXES, "org.jboss.naming rg.jnp.interfaces");
//env.put (Context.)
try {
InitialContext initCtx = new InitialContext( env );
initCtx.bind("x", new Object ());
} catch (NamingException e) {
System.out.println ( "PROBLEMS exception: " + e.getClass().getName() + " \nMessage: " + e.getMessage() );
e.printStackTrace();
}
}
}

an the stack is:

Hi Carlos,

I believe your problem is here:

exception is java.lang.ClassNotFoundException: org.jboss.naming.NamingContextFactory


You need to make sure the class "org.jboss.naming.NamingContextFactory" is in the CLASSPATH of your client application. I don't have immediate access to JBoss, but I believe you'll likely find that class inside the "jboss.jar" file. If not, check the other JARs that are distributed with JBoss; one of them will have the class you need.
