从Tomcat Web应用程序调用在Weblogic上部署的远程Ejb bean

Question

I have created an remote EJB bean using EJB 3.1 and deployed it on web logic 12c. Now through a simple java client I am able to access the remote bean. It is working fine.

Java Client Code:

Context ctx = null;
          Hashtable ht = new Hashtable();
          ht.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory"); 
          ht.put(Context.PROVIDER_URL, "t3://localhost:7001");
        try {
            InitialContext ic = new InitialContext(ht);

}

My next approach is to call this remote bean in a web application that is deployed in Tomcat 7. But it is throwing exception

Caused by: java.lang.ClassNotFoundException: weblogic.jndi.WLInitialContextFactory.

I am using the following code to call the ejb bean : Properties properties = new Properties();

        properties.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
        properties.put("java.naming.factory.url.pkgs", "weblogic.jndi.factories:weblogic.corba.j2ee.naming.url");
        properties.put(Context.PROVIDER_URL, "t3://localhost:7001");
        properties.put( Context.SECURITY_PRINCIPAL, "weblogic");  
        properties.put( Context.SECURITY_CREDENTIALS, "weblogic1");
        try {
          Context ic = new InitialContext(properties); 
}

What to do to make it work.

Thanks

Answer 1

You should have either the wlthint3client.jar or the wlfullclient.jar on your web application classpath. Both are available from weblogic distributions.

More information on their usage can be found here

Answer 2

Work for me adding wlclient.jar and wlthint3client.jar (in this order) on classpath.

In my case I was trying to invoke EJB from the test class. To get the instance I did this way:

weblogic.ejb.spi.BusinessObject obj = (weblogic.ejb.spi.BusinessObject) context.lookup("MyEJBRemoteMappedName#br.com.ejbclient.MyEJBRemote");
br.com.ejbclient.MyEJBRemote myEJB = (br.com.ejbclient.MyEJBRemote) obj._WL_getBusinessObjectHandle().getBusinessObject();

I'm using wls12130.
