I'm using VAJava 3.5 and WebSphere 3.5.
I've asked all our EJB developers to supply a ping() method in any deployed
EJB so that we can test remote connectivity.
I've written a main() method that works fine from within VAJava. Below is
the code.
I've also written a servlet that is basically identical but gets the
parameters for the PROVIDER_URL and beanJndiLookupName from the request
object.
The strange thing is, I've taken the same exact code, pasted it into a
servlet and it fails on the
java.lang.reflect.Method m =
obHome.getClass().getDeclaredMethod("create", new Class[0]);
Even more strange is that the servlet used to work.
Any ideas?
String PROVIDER_URL = "iiop:///";
String beanJndiLookupName = "some/bean/jndiName";
java.util.Hashtable properties = new java.util.Hashtable(2);
properties.put(javax.naming.Context.PROVIDER_URL, PROVIDER_URL);
properties.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY,
"com.ibm.ejs.ns.jndi.CNInitialContextFactory");
// IBM name services
javax.naming.InitialContext initContext = new
javax.naming.InitialContext(properties);
// get ref to remote interface
Object objref = initContext.lookup(beanJndiLookupName);
// get a ref to the home
EJBHome obHome = (EJBHome)
javax.rmi.PortableRemoteObject.narrow(objref, EJBHome.class);
//invoke the create() method
java.lang.reflect.Method m =
obHome.getClass().getDeclaredMethod("create", new Class[0]);
Object obj = m.invoke(obHome, new Object[0]);
m = obj.getClass().getDeclaredMethod("ping", new Class[0]);
Object pingObj = m.invoke(obj, new Object[0]);
System.out.println(pingObj.toString());
