Discover JNDI names inside EAR [wildfly 11]

ainsel Feb 19, 2018 9:56 AM

Hello,

I am making a client to automatically discover available JNDI names on server, and the i have problem with beans that are packed inside ear. The beans deployed directly shows fine, but when I try list beans's inside ear code throw java.lang.StackOverflowError.

Server expose 4 JNDI Paths:

java:global/bean-jar-0.0.1-SNAPSHOT/Counter!org.beanjar.stateful.CounterRemote

java:global/bean-jar-0.0.1-SNAPSHOT/Calculator!org.beanjar.stateless.CalculatorRemote

java:global/any_name/bean-jar/Counter!org.beanjar.stateful.CounterRemote

java:global/any_name/bean-jar/Calculator!org.beanjar.stateless.CalculatorRemote

Client test code:

 final Hashtable<string, string=""> jndiProperties = new Hashtable<>();
        // jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
        jndiProperties.put(Context.INITIAL_CONTEXT_FACTORY, "org.wildfly.naming.client.WildFlyInitialContextFactory");
        jndiProperties.put(Context.PROVIDER_URL, "remote+http://localhost:8080");
        final Context context = new InitialContext(jndiProperties);

 final Context context = new InitialContext(jndiProperties);

NamingEnumeration ctxlst =   context.list("");
        while (ctxlst.hasMore()) {
            NameClassPair ncp = (NameClassPair)ctxlst.next();
            System.out.println( ncp.getClassName() + ": " + ncp.isRelative() +":" + ncp.getName());        }

        NamingEnumeration ctxlst1 =   context.list("bean-jar-0.0.1-SNAPSHOT");
        while (ctxlst1.hasMore()) {
            NameClassPair ncp = (NameClassPair)ctxlst1.next();
            System.out.println( ncp.getClassName() + ": " + ncp.isRelative() +":" + ncp.getName());        }

        NamingEnumeration ctxlst2 =   context.list("any_name");
        while (ctxlst2.hasMore()) {
            NameClassPair ncp = (NameClassPair)ctxlst2.next();
            System.out.println( ncp.getClassName() + ": " + ncp.isRelative() +":" + ncp.getName());        }

        NamingEnumeration ctxlst3 =   context.list("any_name/bean-jar") ;
        while (ctxlst3.hasMore()) {
            NameClassPair ncp = (NameClassPair)ctxlst3.next();
            System.out.println( ncp.getClassName() + ": " + ncp.isRelative() +":" + ncp.getName());        }

Output:

javax.naming.Context: true:bean-jar-0.0.1-SNAPSHOT

javax.naming.Context: true:any_name

java.lang.Object: true:Calculator!org.beanjar.stateless.CalculatorRemote

java.lang.Object: true:Counter!org.beanjar.stateful.CounterRemote

javax.naming.Context: true:bean-jar
