HELP Newbie - CMP Deployment + Configuration

[joycestack]

Hello,

I have my home and remote interfaces, my entity bean is written with the following for retrieving a datasource

Context context = (Context)(new InitialContext()).lookup("java:comp/env");
datasource = (DataSource)context.lookup("jdbc/DefaultDS");
this.datasource=datasource;

I want to use the Hypersonic database. I have a table called Customers in there. I am trying to just connect to database and retrieve and do some simple inserts from my client (a servlet).

This is my ejb-jar.xml file


<?xml version="1.0"?>
<!DOCTYPE ejb-jar PUBLIC '-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN' 'http://java.sun.com/dtd/ejb-jar_2_0.dtd'>

Can someone please tell me what else do I need to deploy a CMP. ? Do I need to place some jars on my classpath? Do I need a jbosscmp-jdbc.xml file? What deployment steps do I need to do once I have my classes written and compiling?

Thanks for the help

Hi,

You need to write somme files :
- ejb-jar.xml
- jaws.jar
- jboss.xml
- jbosscmp-jdbc.xml

Personnally, I use a tool named XDoclet to build all this. I discover it at the moment (as JBoss too ! use to use Orion application server). I don't understand all it is doing at the moment, but it builds me those file, the Home & Remote interfaces of my CMP EJB, and deploy it in JBoss. Perfect for me for testing...

Hey,

Thanks for the reply. I have worked a little with XDoclet alright. I suppose I better use it this time.


Thanks for the reply.

Hello,

I suppose what Im really asking is if Im using Hypersonic what files do I need to edit ? Im just doing a very simple web application to read from db and insert into db.

Go to the following URL and download the JBoss 3.0 Workbook and sample code. The sample code work "out of the box" with Hypersonic and has the examples of the deployment discripter files you need.
