EJBs in Oracle 8i

Question

Is it possible to connect to an EJB running in the Jserver VM from a Java stored procedure?

Answer 1

This is the JSP code which will call a EJB method in the JServer.
This is being tested with 8.1.6.
Step1 :
======
1. Deploy the helloworld EJB example
D:\orant\javavm\demo\examples\ejb\basic\helloworld
Run the makeit.bat.
2. Test the helloworld EJB Demo by running
runit.bat from the above directory.
3. Compile this Class5.java and load into the database using loadjava.
package jsp;
import hello.Hello;
import hello.HelloHome;
import javax.naming.Context;
import javax.naming.InitialContext;
import java.util.Hashtable;
import oracle.aurora.jndi.sess_iiop.ServiceCtx;
public class Class5 extends Object {
public Class5() {
public static String callEJB ()
String serviceURL = "sess_iiop://bldel56.in.oracle.com:2481:V816";
String objectName = "/test/myHello";
String user = "scott";
String password = "tiger";
String s1 = null;
try {
Hashtable env = new Hashtable ();
env.put (Context.URL_PKG_PREFIXES, "oracle.aurora.jndi");
env.put (Context.SECURITY_PRINCIPAL, user);
env.put (Context.SECURITY_CREDENTIALS, password);
env.put (Context.SECURITY_AUTHENTICATION, ServiceCtx.NON_SSL_LOGIN);
Context ic = new InitialContext (env);
HelloHome hello_home = (HelloHome)ic.lookup (serviceURL + objectName);
Hello hello = hello_home.create ();
s1 = hello.helloWorld ();
catch (Exception e) {e.printStackTrace();}
return s1;
4. Create the PL/SQL Function for calling the EJB Method.
create or replace FUNCTION CALLEJB RETURN VARCHAR2
AS LANGUAGE JAVA
NAME 'jsp.Class5.callEJB() return java.lang.String';
5. open the sql*plus and connect as scott/tiger.
select callejb from dual;
It should Display
CALLEJB
Hello client, your javavm version is 8.1.6.
