WAS7 cluster member: can't lookup from WSAD 5.1.2

[Samuel Lima]

Hi,

I have a web application running on WSAD 5.1.2 in my local machine, and I want to "lookup" an EJB running on a remote WAS 7.

It's fine when the remote app (in WAS7) is in a single server (i.e. boostrap port of a non cluster member).

But when the remote app is in a cluster member, the lookup returns ServiceUnavailableException.

Checked with "dumpNameSpace.sh -url corbaloc:iiop:li201:2813/NameServiceServerRoot" (the bootstrap of a cluster member) which is fine.

Checked the remote SystemOut.log, but found no exceptions.

I Read WAS7 troubleshooting manual: http://publib.boulder.ibm.com/infocenter/wasinfo/v7r0//index.jsp?topic=/com.ibm.websphere.base.doc/info/aes/ae/rcli_troubleshoot.html

I followed the troubleshooting procedures, but none of the suggested causes were the causes.

I'm using the following code:

String jndiName = "ejb/ServicoCalculoSeguroHome";
        Hashtable env = new Hashtable();
        env.put(PROPS.JNDI_CACHE_OBJECT, PROPS.JNDI_CACHE_OBJECT_NONE);
        env.put(Context.PROVIDER_URL, "corbaloc:iiop:li201:2813/NameServiceServerRoot");

        InitialContext ctx = new InitialContext(env);

        Object obj = ctx.lookup(jndiName);
        ServicoCalculoSeguroHome home = (ServicoCalculoSeguroHome)PortableRemoteObject.narrow(obj,ServicoCalculoSeguroHome.class);
        ServicoCalculoSeguro bean = home.create();
        String retorno = bean.calcularSeguroXML("banana");

Can anyone help me, please?

The complete exception stack trace is:
