problem trying to deploy a simple helloworldejb.jar

rsood72 Jul 31, 2006 9:28 AM

Whenever I triy to deploy my helloworldejb.jar, i get the following exception - I have looked everywhere in the forum and out of forum but cannot figure out what the problem is. If someone can help me I will appreciate it. Right after the error I have also pasted the contents of my ejb-jar.xml and jboss.xml

Post the entire stack trace that you are seeing. Also, post the contents of your ejb-jar.xml and jboss.xml since they did not show up properly the last time. Make sure you wrap the contents in the Code tags(use the Code button, which is provided above while posting)

Hmm... Strange there are no errors messages above this stacktrace.
Traverse to C:/jboss-3.2.3/server/default/deploy/ directory from the command prompt and run the following command and post the output:

jar -tf HelloWorldEJB.jar

This will show the contents of the jar file. Just wanted to make sure that the packaging is proper

Do I have to do anything with Jndi ?
in jboss.xml file i have said that the jndi name is jndi/Hello

Do I need to register this anywhere in the Java Naming Directory implementation provided by Jboss or is it done automatically?

You dont have to do anything with that. JBoss will automatically bind your bean to that jndi name.
How big is that jar file? If its not huge, mail it to jai_forums2005@yahoo.co.in. Let me try it at my end.

which means that you have not defined the ejbCreate method in your HelloBean class. Provide a blank implementation for the same, in your HelloBean class and deploy it:

public void ejbCreate()
 {
 }

That should work.

ok i will try that..here help me with the theory behind this..i used to know it..have kind of gotten confused..
the way it works is that create method is called by the container automatically for us...if we want to do anything special during the creation of the bean we should do that in ejbCreate which is called by create..right ?

jaikiran Jul 31, 2006 11:11 AM (in response to rsood72)

The ejbCreate method will be called when the client invokes the create() method on the home interface. The lifecycle of the EJB is explained here:

http://java.sun.com/j2ee/tutorial/1_3-fcs/doc/EJBConcepts9.html

As per the specs:

The session bean class must define one or more ejbCreate<METHOD> methods whose signatures must follow these rules:
? The method name must have ejbCreate as its prefix.
? The method must be declared as public.
? The method must not be declared as final or static.
? The return type must be void.
? The method arguments must be legal types for RMI/IIOP if there is a create<METHOD> corresponding
to the ejbCreate<METHOD> method on the session bean?s remote home interface.
? A stateless session bean must define a single ejbCreate method, with no arguments.
? The throws clause may define arbitrary application exceptions, possibly including the javax.ejb.CreateException.

Looks like some changes were made in your log4j.xml which might have disabled logging for the org.jboss.ejb.EJBDeployer class. The log4j.xml is present in %JBOSS_HOME%/server/default/conf directory.
