Deploying a bean  in Oracle9ias

1. Create the Bean classes. and compile it in the corresponding Folder "d:\app1\app\ecomp"
that u have set in the application.xml in the config folder
Sample

 <web-module id="DefaultWebApp" path="d:\app1\app\web" />
 <ejb-module path="d:\app1\app\ecomp" remote="false" />
 <client-module path="d:\app1\app\ecomp" remote="false" />
 <persistence path="../persistence" />

2. Modify the ejb-jar.xml in the path "d:\app1\app\ecomp\META_INF" folder

EJB-jAR XML

<?xml version="1.0"?>
<!DOCTYPE ejb-jar PUBLIC '-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 1.1//EN' 'http://java.sun.com/j2ee/dtds/ejb-jar_1_1.dtd'>

<ejb-jar>
