hi,

I had a ejb-jar with a single local bean( i.e. a bean and local home and local interface). I deployed the bean first time with a local-jndi-name, say "A". It deployed successfully. I changed the local-jndi-name, say "B" and repackaged it in a different jar. When I trying to deply it, the below exception is thrown. Is this the excepted behaviour? or Where am I going wrong?
Excepting the reply very soon.

Here is my ejb-jar.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE ejb-jar PUBLIC
"-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN"
"http://java.sun.com/dtd/ejb-jar_2_0.dtd">

<ejb-jar>
Sample Application
<display-name>Example EJB</display-name>
<enterprise-beans>

<ejb-name>Data</ejb-name>
<local-home>beans.example.DataHome</local-home>
beans.example.Data
<ejb-class>beans.example.DataBean</ejb-class>
<persistence-type>Bean</persistence-type>
<prim-key-class>java.lang.Integer</prim-key-class>
false

</enterprise-beans>
</ejb-jar>

I used this ejb-jar xml for both the deployment.

Here is my jboss.xml for the first deployment:

<?xml version="1.0" encoding="UTF-8"?>

<enterprise-beans>

<ejb-name>Data</ejb-name>
<local-jndi-name>example/Data</local-jndi-name>

</enterprise-beans>


Here is my jboss.xml for the second deployment:

<?xml version="1.0" encoding="UTF-8"?>

<enterprise-beans>

<ejb-name>Data</ejb-name>
<local-jndi-name>example/Data11</local-jndi-name>

</enterprise-beans>


Here is the stack trace of the exception:
