How to access to Business Components deployed to Oracle 8i

Question

Hi,
I succeded in deploying an Application Module to Oracle 8i and publishing it through JNDI.
The test wizard is also ok.
Now I obviously want to access the module from a client.
The lookup phase is successful, but what I get back is a oracle.jbo.common.remote.corba.RemoteApplicationModuleHome, and I suppose I have to invoke its create() method to get some actual Module object reference.
The proble is that the create() method wants a strange SessionInfo parameter, that seems undocumented.
Does anyone know how to solve the problem ?
Or where is the necessary documentation ?
Thanks in advance

Hello!
Sorry for the delayed response...
Here is an EJB client for a BC4J-EJB in 8i:
package tester;
import java.lang.*;
import oracle.jbo.*;
import oracle.jbo.JboContext;
import java.util.Hashtable;
import javax.naming.*;
/*This project properties should include:
JBO EJB Runtime, JBO EJB Client and User created Library .
public class BC4J_EJB_test extends Object {
static Hashtable env = new Hashtable(10);
public static void main(String[] args) {
// set up variables for environment settings
// Modify User, Password, HostName, SID and DeployedMod
String User = new String("BUD");
String Password = new String("SPUD");
String DeployedMod = new String("BC4J.BC4JModule");
String HostName = new String("jtora815.us.oracle.com");
String ConSid = new String("ORCL");
//IIOP Port MUST BE A STRING!!!!!!!!!!
String ConPort = new String("2481");
String ApplicationPath = new String("test/ejb");
String Conn = new String("jdbc racle:kprb:");
try {
// set variables in hashtable to be used as the environment
env.put(Context.INITIAL_CONTEXT_FACTORY, JboContext.JBO_CONTEXT_FACTORY);
env.put(Context.SECURITY_PRINCIPAL, User);
env.put(Context.SECURITY_CREDENTIALS, Password);
// only difference other than libraries from 8i Corba
env.put(JboContext.DEPLOY_PLATFORM, JboContext.PLATFORM_EJB);
env.put(JboContext.APPLICATION_PATH, ApplicationPath);
env.put(JboContext.HOST_NAME, HostName);
env.put(JboContext.CONNECTION_PORT, ConPort);
env.put(JboContext.ORACLE_SID, ConSid);
// setup application module variable
ApplicationModule appMod = null;
javax.naming.Context ic = new InitialContext(env);
ApplicationModuleHome home = (ApplicationModuleHome)ic.lookup(DeployedMod);
appMod = home.create();
//connect application module
appMod.getTransaction().connect(Conn);
/* At this point you have the application module connected, now do what you want
here. This example just iterates through the dept table and prints each row */
ViewObject deptVo = appMod.findViewObject("DeptView");
Row r = deptVo.first();
do{
System.out.println(r.getAttribute("Deptno")+" "+
r.getAttribute("Dname") +" "+
r.getAttribute("Loc"));
r = deptVo.next();
}while( deptVo.getCurrentRowSlot()!= deptVo.SLOT_BEYOND_LAST );
catch(Exception Oops) {
Oops.printStackTrace();
System.out.println(Oops.getMessage());
Hope this helps.
Regards,
Arun
