Integrete with Websphere 5.0 example

Question

Write class like this:
package com.test.kodo;
import com.ibm.websphere.management.AdminService;
import com.ibm.websphere.management.AdminServiceFactory;
import com.ibm.websphere.runtime.CustomService;
import javax.naming.*;
import java.util.*;
import javax.management.*;
import com.solarmetric.kodo.impl.jdbc.ee.EEPersistenceManagerFactory;
public class KodoWebsphere implements CustomService, NotificationListener {
     private static String JNDIName = "PMFactory";
private Properties props;
private void log(String s) {
System.out.println("JDO Kodo: " + s);
public void initialize(Properties properties) throws Exception {
log("KodoWebsphere.initialize");
AdminService adminservice = AdminServiceFactory.getAdminService();
adminservice.addNotificationListener(adminservice.getLocalServer(), this,
null, null);
props = properties;
public void shutdown() throws Exception {
log("KodoWebsphere.shutdown");
public void handleNotification(Notification notification, Object obj) {
String s = notification.getType();
if(s.equals("j2ee.state.running"))
bind();
private void bind() {
log("KodoWebsphere.bind");
          try {
               String jndi = (String)props.get ("jndiname");
               if (jndi == null || jndi.length () == 0)
                    jndi = JNDIName;
               EEPersistenceManagerFactory factory = new EEPersistenceManagerFactory
               InitialContext ic = new InitialContext ();
               ic.bind (jndi, factory);
} catch(Exception exception) {
log("KodoWebsphere.bind failed: " + exception);
exception.printStackTrace();
Now do following:
Copy relevent class and jar file to your WebSphere server lib/ext
directory (e.g. ${was.home}/lib/ext).
Copy lib/jdo.jar to the jre/lib/ext directory of the Java VM used to run
WebSphere (e.g. ${was.home}/java/jre/lib/ext).
Logon to the WebSphere Administrative Console.
Select Application Servers -> YourServer -> Custom Services and click New.
Tick the startup box.
Enter com.test.kodo.KodoWebsphere in the Classname field.
Enter Kodo Websphere in the Display name field.
Enter the right classpath in the Classpath field.
Click OK.
Now you can use it like this:
public class JDOFactory {
     private static PersistenceManagerFactory pmf;
     static {
          try {
               pmf = (PersistenceManagerFactory)(new
InitialContext()).lookup("PMFactory");
          } catch (NamingException e) {
               //PMFactory JNDI not found
     public static PersistenceManager getPersistenceManager() {
          if (pmf != null) {
               return pmf.getPersistenceManager();
          } else {
               return null;
