I can post the major parts ..
The Interface:
| package com.ist.beans.interfaces.local;
|
| import java.io.Serializable;
| import javax.ejb.Local;
|
|
| @Local
| public interface Notification {
| ...
| public Object getNotification(String topic, String user, int timeOut);
| ...
| }
|
The bean:
| package com.ist.beans.session;
|
| import java.io.Serializable;
| import java.sql.Connection;
| import java.sql.ResultSet;
| import java.sql.SQLException;
| import java.sql.Statement;
| import java.util.ArrayList;
| import java.util.List;
|
| import javax.ejb.Local;
| import javax.ejb.Remote;
| import javax.ejb.Stateless;
| import javax.naming.InitialContext;
| import javax.naming.NamingException;
| import javax.sql.DataSource;
|
| import org.jboss.annotation.ejb.LocalBinding;
| import org.jboss.annotation.ejb.RemoteBinding;
|
| @Stateless
|
| @Local ({com.ist.beans.interfaces.local.Notification.class})
| @LocalBinding (jndiBinding="ejb/local-notification")
|
| @Remote ({com.ist.beans.interfaces.remote.Notification.class})
| @RemoteBinding (jndiBinding="ejb/notification")
| public class NotificationBean implements
com.ist.beans.interfaces.remote.Notification,
|
com.ist.beans.interfaces.local.Notification {
| private static final String NULL = "NULL";
|
| ...
| public Object getNotification(String topic, int timeOut) {
| return getObjectFromTopic(topic, timeOut);
| }
| ...
| private Object getObjectFromTopic(String topic, int timeOut) {
| Object value = null;
|
| //*Internal Processing ... database access ... blah ... blah
|
| return value;
| }
|
| }
|
Finally the client ... in this case the client is a web service ... if I use
the same lookup code snippet in a client on my workstation ... works picture
perfect ... However as a servlet it never makes it past construction.
| package com.ist.webservice;
|
| import javax.naming.InitialContext;
| import com.ist.beans.interfaces.local.Notification;
|
| public class NotificationWebService implements NotificationService {
| private Notification notification;
|
| public NotificationWebService() {
| super();
| try {
| InitialContext context = new InitialContext();
|
| Object objRef =
context.lookup("ejb/local-notification");
|
| Class c = objRef.getClass();
| Class[] interfaces = c.getInterfaces();
| for (int i=0; i<interfaces.length; i++) {
| System.out.println(i + " : " + interfaces);
| }
|
| notification = (Notification)objRef;
| }
| catch (Throwable t) {
| throw new RuntimeException(t);
| }
| }
|
| ...
| }
|
|
Just incase ... web.xml
| <?xml version="1.0" encoding="UTF-8"?>
| <web-app version="2.5"
| xmlns="http://java.sun.com/xml/ns/javaee";
| xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
| xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd";>
| <display-name>Notification Service</display-name>
| <description>Notification Web Service Interaface</description>

<servlet-class>com.ist.webservice.NotificationWebService</servlet-class>

| <url-pattern>/NotificationServlet</url-pattern>
| </servlet-mapping>
| <session-config>
| <session-timeout>10</session-timeout>
| </session-config>
| </web-app>
|
and the webservices.xml
| <webservices xmlns="http://java.sun.com/xml/ns/j2ee";
| xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
| xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee

I am puzzled how someting can indicate it implements an interface when querying
it through reflection, and then throw the ClassCastException when I try to do
it.
To make some people happy here I have unfortunatly been forced to muck up these
so pardon my fat-fingeredness if I missed something.
Thanks.
