Hi all,
I trying to call an EJB from a Java Compute Node, but I am getting the exception below:
javax.naming.NoInitialContextException: Cannot instantiate class: com.ibm.websphere.naming.WsnInitialContextFactory [Root exception is java.lang.ClassNotFoundException: com.ibm.websphere.naming.WsnInitialContextFactory]
I have the jars containing the com.ibm.websphere.naming.WsnInitialContextFactory in my java project classpath.
IIB version 9
The Java code is below
| Code: |
private void doSomething(){
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,"com.ibm.websphere.naming.WsnInitialContextFactory");
env.put(Context.PROVIDER_URL,"corbaloc::192.168.182.135:9104");
EjbSampleRemoteInterface ejbRemote = null;
Object obj;
try{
InitialContext ctx = new InitialContext(env);
obj = ctx.lookup("EjbSample");
if(obj instanceof EjbSampleRemoteInterface){
ejbRemote = (EjbSampleRemoteInterface) obj;
}
if(ejbRemote != null){
System.out.println(ejbRemote.doSomething());
}
}catch(NamingException ne){
System.err.println("Nao foi possivel lookup");
ne.printStackTrace();
}
} |
Many thanks
Savio |

Thinking about the overall architecture...
Instead of reaching out to the EJB over RMI, should you maybe be trying to do the same over messaging and have the J2EE server call the EJB internally from messaging? (MDB to EJB?)
