JNDI-Name of a Session Bean

[Former Member]

Hello everybody,

I am working with the CE 7.1 and I am trying to deploy a session Bean with an aberrant JNDI-Name. The Bean is named JCoListenerBean but a client is looking for this Bean via JNDI-lookup using the name “IDOC_INBOUND_ASYNCHRONOUS”. That is why I have to change the JNDI-Name of the JCoListenerBean to “IDOC_INBOUND_ASYNCHRONOUS”. I have tried to do this by using annotations and by adjusting the deployment descriptor (ejb-j2ee-engine.xml). Both ways do not have the designated result.

This is my ejb-j2ee-engine.xml

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

<ejb-j2ee-engine xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:noNamespaceSchemaLocation="ejb-j2ee-engine_3_0.xsd">

<enterprise-beans>

<enterprise-bean>

<ejb-name>JCoListenerBean</ejb-name>

<server-component-ref>

<name>IDOC_INBOUND_ASYNCHRONOUS</name>

<jndi-name>IDOC_INBOUND_ASYNCHRONOUS</jndi-name>

</server-component-ref>

</enterprise-bean>

</enterprise-beans>

</ejb-j2ee-engine>

Anyone knows how to change the JNDI-Name of a session Bean using NetWeaver and the NW Developer Studio. Ideal would be a link to a code example.

Thanks, Stefan

Hi.

I have my ejb-jar like this:

<ejb-jar

xmlns="http://java.sun.com/xml/ns/j2ee"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

id="ejb-jar_ID"

version="2.1"

xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/ejb-jar_2_1.xsd">;

<display-name>MyBeanImplementation</display-name>

<icon/>

<enterprise-beans>

<session>

<icon/>

<ejb-name>MyBean</ejb-name>

<local-home>com.me.MyBeanLocalHome</local-home>

<local>com.me.MyBeanLocal</local>

<ejb-class>com.me.MyBean</ejb-class>

<session-type>Stateless</session-type>

<transaction-type>Container</transaction-type>

</session>

</enterprise-beans>

</ejb-jar>

the ejb-j2ee-engine.xml looks like this.

<ejb-j2ee-engine

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:noNamespaceSchemaLocation="ejb-j2ee-engine.xsd">

<enterprise-beans>

<enterprise-bean>

<ejb-name>MyBean</ejb-name>

<session-props>

<property>

<property-name>InitialSize</property-name>

<property-value>1</property-value>

</property>

<property>

<property-name>MaxSize</property-name>

<property-value>1</property-value>

</property>

<property>

<property-name>ResizeStep</property-name>

<property-value>1</property-value>

</property>

</session-props>

</enterprise-bean>

</enterprise-beans>

</ejb-j2ee-engine>

And then it can be accessed in code like this:

Context context = new InitialContext();

String EJB_LOC = "java:comp/env/ejb/MyBean";

MyBeanLocalHome beanLocalHome = (MyBeanLocalHome)PortableRemoteObject.narrow(context.lookup(EJB_LOC),MyBeanLocalHome.class);

Hope this helps.

Hi Andrew, thanks for your answer.

I think you have implemented a Bean called MyBean which is locaetd in the package com.me. If you are searching for this Bean, you use the lookup-String "java:comp/env/ejb/MyBean". Isn't it?

My problem is, that I have to find my JCoListenerBean with the lookup-String "IDOC_INBOUND_ASYNCHRONOUS".

Do you have any idea how to modify a Bean (your MyBean) that they could be found with my lookup-String ("IDOC_INBOUND_ASYNCHRONOUS")?

Thanks

I would imagine that you should be able to use JNDI to put a reference to the bean in the context to look up.

Im guessing here, but i think you should be able to use the bind() method on the initialContext to place a reference to an object (in our case the bean), with your custom name...

I dont know that much about putting stuff into the jndi unfortunately, just getting stuff out.

I would try putting it in the constructor method, or ejbCreate..

Regards,

Andrew
