<div class="jive-rendered-content"><p>Hi,</p><p>I'm trying to get an ejb3 from a remote host (that uses jboss 5.1) inside jboss 4.x. The code I use is the following:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>public void myFunction() {</p><p>        Properties jndiProps = new Properties();</p><p>        jndiProps.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");</p><p>        jndiProps.setProperty(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interface");</p><p>        jndiProps.setProperty(Context.PROVIDER_URL, "jnp://{<strong>host-ip</strong>}:{<strong>host-jndi-port</strong>}");</p><p>        try {</p><p>            FooInterface foo = (FooInterface)(new InitialContext(jndiProps)).lookup("{<strong>jndi-name</strong>}");</p><p>            foo.doSomething();</p><p>        } catch (Exception e) {</p><p>            e.printStackTrace();</p><p>        }</p><p>        </p><p>    }</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>But doing that, I get a ClassCastException here "FooInterface foo = (FooInterface)(new InitialContext(jndiProps)).lookup("{<strong>jndi-name</strong>}");":</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p> java.lang.ClassCastException: javax.naming.Reference cannot be cast to my.package.FooInterface</p><p>   at com.phi.phirxportal.SecondOpinionRequestBean.myFunction(SecondOpinionRequestBean.java:272)</p><p>   at com.phi.phirxportal.SecondOpinionRequestBean.checkExam(SecondOpinionRequestBean.java:170)</p><p>   at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)</p><p>     at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)</p><p>    at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)</p><p>     at java.lang.reflect.Method.invoke(Method.java:597)</p><p>     at org.jboss.el.util.ReflectionUtil.invokeMethod(ReflectionUtil.java:335)</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Host ip, jndi name and host jndi port are correct. I can't figure out how to get my FooInterface from a javax.naming.Reference object.</p><p>The Reference object toString method returns something like:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Reference Class Name: Proxy for: my.package.FooInterface</p><p>Type: ProxyFactoryKey</p><p>Content: ProxyFactory/.....</p><p>Type: EJB Container Name</p><p>Content: jboss.j2ee:ear=xxx.ear,jar=xxx.jar,name=FooBean,service=EJB3</p><p>Type: Proxy Factory is Local</p><p>Content: false</p><p>Type: Remote Business Interface</p><p>Content: my.package.FooInterface</p><p>Type: Remoting Host URL</p><p>Content: socket://hostpcname:3873/?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Is there a way to do that or does it depends on something else (libraries, configuration, jboss version...)?</p><p>Thanks in advance.</p></div>
