Hello help please
I am using JBoss Application Server 4.0.3SP1 . I need an ejb which needs to
connect to Oracle Containers for J2EE 10g (10.1.3.0.0) Developer's Preview 4
and get all the MBeans information from there.
First I tried to connect through the basic Java Program given below, which
needed a application-client.xml in META-INF directory to refer. That worked
fine.
import javax.management.j2ee.*;
import javax.management.*;
import javax.management.remote.*;
import javax.ejb.*;
import javax.naming.*;
import javax.rmi.*;
public class Main {
public static void main(String[] args) throws Exception {
Hashtable props = new Hashtable();
props.put(Context.PROVIDER_URL, "ormi://trainingtest1:23791/default");
props.put(Context.SECURITY_PRINCIPAL, "oc4jadmin");
props.put(Context.SECURITY_CREDENTIALS, "welcome");
props.put(Context.INITIAL_CONTEXT_FACTORY
,"com.evermind.server.ApplicationClientInitialContextFactory");
InitialContext ctx = new InitialContext(props);
Object o = ctx.lookup("java:comp/env/ejb/mgmt/MEJB");
ManagementHome home = (ManagementHome)PortableRemoteObject.narrow(o,
ManagementHome.class);
Management mejb = home.create();
}
}
The Same program when i tried to implement through EJB in JBoss it did not
function. So I tried to implement in servlet first and then in EJB. And also i
kept the application-client.xml file in META-INF directory inside classes
folder. When i try to run the following servlet program by packagin to a ear
file the below given exception is thrown. I cant come out the error. can any
one please help me in comming out of this problem.
the servlet program is
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import javax.naming.*;
import javax.management.j2ee.*;
import javax.management.*;
import javax.management.remote.*;
import javax.ejb.*;
import javax.naming.*;
import javax.rmi.*;
import java.util.*;
public class Test extends HttpServlet {
public void doGet (HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
PrintWriter out=response.getWriter();
String msg="";
try{
Hashtable props = new Hashtable();
props.put(Context.PROVIDER_URL, "ormi://localhost:23791/default");
props.put(Context.SECURITY_PRINCIPAL, "oc4jadmin");
props.put(Context.SECURITY_CREDENTIALS, "welcome");
props.put(Context.INITIAL_CONTEXT_FACTORY
,"com.evermind.server.ApplicationClientInitialContextFactory");
InitialContext ctx = new InitialContext(props);
Object o = ctx.lookup("java:comp/env/ejb/mgmt/MEJB");
ManagementHome home = (ManagementHome)PortableRemoteObject.narrow(o,
ManagementHome.class);
out.flush();
Management mejb = home.create();
}catch(Exception e){
e.printStackTrace();
}
out.println("Done");
out.close();
}
public void destroy(){}
}
