RE: Message Driven Beans
Implementing a Message-Driven Bean in Orion.
(Tested with orion 1.5.4)
1.) == The MDB code - LogBean
package mycode.ejb.mdb;
import javax.ejb.*;
import javax.jms.*;
public class LogBean implements MessageDrivenBean, MessageListener {
protected MessageDrivenContext ctx;
public void setMessageDrivenContext(MessageDrivenContext ctx) {
this.ctx = ctx;
}
public void ejbCreate() {
System.out.println("ejbCreate()");
}
public void onMessage(Message msg) {
TextMessage tm = (TextMessage) msg;
try {
String text = tm.getText();
System.out.println("Received new message : " + text);
}
catch(JMSException e) {
e.printStackTrace();
}
}
public void ejbRemove() {
System.out.println("ejbRemove()");
}
}
2.) == The deployment descriptor (ejb.jar)
http://java.sun.com/j2ee/dtds/ejb-jar_1_2.dtd";>
Test Message Bean
A test of message beans
Log
mycode.ejb.mdb.LogBean
Container
javax.jms.Queue
3.) == Activate (uncomment) jms in server.xml
4.) == Update jms.xml to include the queue
Test queue for MDB LogBean
5.) == Update web.xml to include the resource references to
jms factory and queue
jms/theQueueConnectionFactory
javax.jms.QueueConnectionFactory
Container
jms/theLog
javax.jms.Queue
Container
6.) == Send a message to the jms queue from application code
(jsp in this case)
<%@ page import="javax.naming.*" %>
<%@ page import="javax.jms.*" %>
<%
try
{
Context context = new InitialContext();
QueueConnectionFactory factory =
(QueueConnectionFactory)context.lookup("java:comp/env/jms/theQueueConnectionFactory");
QueueConnection connection = factory.createQueueConnection();
Queue queue = (Queue)context.lookup("java:comp/env/jms/theLog");
connection.start();
QueueSession sess = connection.createQueueSession(false,
QueueSession.AUTO_ACKNOWLEDGE);
QueueSender sender = sess.createSender(queue);
int delivery_mode = DeliveryMode.PERSISTENT;
TextMessage message = sess.createTextMessage("well hello there...");
sender.send(message, delivery_mode, 1, 0);
sess.close();
connection.close();
} catch(JMSException e) {
System.err.println("JMS Communication error: " + e.getMessage());
} catch(NamingException e) {

Re: CMP entity bean deployment compilation errors
A follow-up to this issue, which I feel is resolved. I tried 1.5.4 and then encountered the following compilation errors: CodeListsEBLocalHome_EntityHomeWrapper10.java:156: Exception java.rmi.RemoteException must be c aught, or it must be declared in the throws clause of this method. EvermindEntityContext finderContext = this.getContextInstance(thread); Which I then saw in another message here. I did some more investigation and found that the inclusion of the and elements as well as the and elements in my ejb-jar.xml was causing the original compilation errors. I then commented out either the / or the / and the deployment/compilation of generated classes worked. Seems you can possibly only use one of the pair. This is okay for me as I normally use the session bean as a facade pattern , so I should be fine just using the / pair.

CMP entity bean deployment compilation errors
I've created a CMP entity bean based on some examples I've seen and am encountering some compilation errors on the generated wrapper classes at deployment time. Its seems the getter/setter methods and the remove method are not recognized or available in the generated wrapper classes.

RE: XSL and Sitemesh on Orion
Dearest elephantwalker and other dearest friends,
I have a doubt in this xsl rendering.
I used xalan and xerces parser which orion uses for xml to html rendering. I
used my own xsl servlet to port my code to any application server which is
not having an xsl servlet. But I am ending up in one trouble. Transformation
is working fine. But if I need to output as xml,
I will use response.setContentType("text/xml"); this works fine in servlets.
But when I use the same in jsps in an ear file, this donot happen. Can we
change the content type of jsp's?
thanks,
Prasanth.

Re: Re: how to shutdown orion app server?
Hi. Again.
Now. The code seems correct. Except, the
url, that MAY require to be of the type:
ormi://localhost/Your_App_Name.
If you have deployed your beans in an
application, and NOT in the default APP, you HAVE to use the url with the
app_name at the end.
in config/server.xml
in properties:
java.naming.provider.url=ormi://your.host.your.domain/Your_App_Name
or
java.naming.provider.url=ormi://localhost/Your_App_Name << FOR LINUX
MAINLY!
in java code:
p.put(Context.PROVIDER_URL,
"ormi://localhost/Your_App_Name");
Then you will find your ejbs.
I would sincerly offer you to look-up the
name of the bean without any prefixes. It is hard to move to other app server
sometimes. In your case if you have no ejb-link, ejb-ref and so on stuff, just
look-up OrgOrganizations:
ctx.lookup("OrgOrganizations");
Also let's note, that if you use the
java:comp/* context it may not port well on different servers.
Lachezar.
P.S. Give it a try and write
again.
but i can't look up my ejb,how to config it.
thanks
Hi.
Make sure you remove
the 'deactivated="false"' for admin in
config/principals.xml

Re: how to shutdown orion app server?
That command seems to hang on linux 2.4.x / 1.3.1 as soon as you've deployed something. It works great on win2k, though, so I suspect the linux JVM.

Re: how to shutdown orion app server?
Hi Liu,
Did you run
orion -install
when you installed orion (or changed admin password in principals.xml)?
This username/password should correspond with the username/password from
the jndi.properties file of the client application
