JNDI Access from Sun JRE on Websphere 6
thomas....@avignon.inra.fr
I'm trying to access to jndi resources on a Websphere 6 server from a tomcat 5.5 app running under Sun JRE in order to send JMS message.
This is my main code :
Hashtable<String, String> h = new Hashtable<String, String>();
h.put(Context.SECURITY_PRINCIPAL, "guest");
h.put(Context.SECURITY_CREDENTIALS, "guest");
h.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");
h.put(Context.PROVIDER_URL, "iiop://localhost:2809");
Context jndi = null;
QueueConnectionFactory conFabrique = null;
try {
jndi = new InitialContext(h);
if (jndi != null) {
System.out.println("jndi = " + jndi);
Hashtable hash = jndi.getEnvironment();
Enumeration<String> keys = hash.keys();
while (keys.hasMoreElements()) {
String key = (String) keys.nextElement();
System.out.println(key + " : " + hash.get(key));
}
conFabrique = (QueueConnectionFactory) jndi
lookup(connectionFactoryName);
queue = (Queue) jndi.lookup(queueName);
} else {
System.out.println("JNDI non initialisé");
}
} catch (NamingException e) {
e.printStackTrace();
}
And this is the exception :
javax.naming.NamingException: Failed to initialize the ORB [Root exception is java.lang.ClassCastException: com.sun.corba.se.impl.orb.ORBImpl]

This exception is thrown at jndi.getEnvironment(), or when I discard this line, at jndi.lookup.
Of course I put in CLASSPATH of Sun's JRE all jar files in IBM_JDK_HOME/jre/lib and IBM_JDK_HOME/jre/lib/ext
If I run my code with IBM JRE, it runs without any error!!! How can I make it run on Sun's JRE?
I think maybe I can add an h.put(...) to say how to get some class but I really don't know what...
Please help me!!
Thanks!!

Exactly what I want!
Thanks!
It works pretty good now!
Still just a security problem but I will try to resolve it.
Thanks again

I tried the code below but got exception on "home.create()"
Put the j2ee.jar in the "\Tomcat 5.5\common\lib" directory.
Tried some sites but didn´t work.
Any hint? Has someone tried it successfully?
Thanks.
Properties env = new Properties();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
env.put(Context.PROVIDER_URL, "iiop://li09:2809");
InitialContext ctx = new InitialContext(env);
Object obj = ctx.lookup("cell/nodes/li09Node01/servers/server1/ejb/com/porto/informatica/sasi/eai/ChamadoTecnicoSmartHome");
ChamadoTecnicoSmartHome home = (ChamadoTecnicoSmartHome)PortableRemoteObject.narrow(obj, ChamadoTecnicoSmartHome.class);
ChamadoTecnicoSmart remote = home.create();

Read up on "pluggable application clients" in the WAS infocenter.

Thanks again Paul,
I did it but when I saw it takes about 36mb to generate a "thin" client for Sun JRE I decided to dig a litle deeper.
I made it copying the jars (below in this post) from WAS 6 to the lib folder of the web project.
Just couldn´t use the com.ibm.websphere.naming.WsnInitialContextFactory, had to use com.sun.jndi.cosnaming.CNCtxFactory.
It also only worked using fully qualified name for lookup: "cell/nodes/li09Node01/servers/server1/ejb/com/porto/informatica/model/CadastroFuncionarioModelHome" instead of just "ejb/com/porto/informatica/model/CadastroFuncionarioModelHome"
I also worked with falt tolerance on cluster throught corbaloc
Started two servers in cluster (9812, 9816) then stopped the first, tried the lookup, then started the first and stopped the next and everything worked well.
Next step I´m going to try Tomcat 4.1.3 with jre 1.4.
Below the code:
Hashtable env = new Hashtable();
env.put("java.naming.factory.initial", "com.sun.jndi.cosnaming.CNCtxFactory");
env.put("java.naming.provider.url", "corbaloc::li38:9812,:li38:9816");
InitialContext initContext = new InitialContext(env);
Object obj = initContext.lookup("cell/clusters/clusterMdlCorp01/ejb/com/porto/informatica/model/CadastroFuncionarioModelHome");
CadastroFuncionarioModelHome home = (CadastroFuncionarioModelHome)PortableRemoteObject.narrow(obj, CadastroFuncionarioModelHome.class);
CadastroFuncionarioModel remote = home.create();
CadastroFuncionariosVO func = remote.obterFuncionario(new Integer(603151), new Short("1"), "F");
WAS6 jars:
-----------
antlr.jar
appprofile.jar
ecutils.jar
ejbcontainer.jar
ejbportable.jar
ivjejb35.jar
namingclient.jar
pm.jar
pmimpl.jar
ras.jar
rsadaptercci.jar
rsaexternal.jar
runtime.jar
runtimefw.jar
standard.jar
utils.jar
vaprt.jar
wsexception.jar
j2ee.jar (had to remove javax.servlet package conflicting with tomcat jars)
third part jars:
----------------
commons-beanutils.jar
commons-collections.jar
commons-digester.jar
log4j-1.2.11.jar

you're on your own. The only supported configuration is the thin client.

I tried running stand alone JMS Client sending a jms message to a topic on Websphere 6.0 node. I ran into the following issue.
javax.naming.NamingException: Failed to initialize the ORB [Root exception is java.lang.ClassCastException: com.sun.corba.se.impl.orb.ORBImpl]
at com.ibm.ws.naming.util.Helpers.getOrb(Helpers.java:318)
Then I installed IBM Client for JMS on J2SE with IBM WebSphere Application Server as mentioned in http://www-01.ibm.com/support/docview.wss?uid=swg24012804. I used the option jms_jndi_ibm.
Now when I run my application, I get the following error. Please help me on this. I attached the custom.bat, my source code. This works fine if it was run inside WAS.
