EJB Deployement Error

[pipo]

Hello,

I try to develop a simple EJB example (the Helloworld example). But I have got errors (see the end of this message) when I put my jar file in the deploy directory of JBoss. I dont' know where it is wrong!

(BTW I havn't use xdoclet or ant to generate my files)
Thank you for your kind assistance.

The deployer is complaining because you have not provided fully qualified names for the interfaces of your EJB. This is required to be placed in a file called ejb-jar.xml located in META-INF of the bean's jar. An example of a simple EJB declaration is:

<?xml version="1.0"?>
<!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN" "http://java.sun.com/j2ee/dtds/ejb-jar_2_0.dtd">
<ejb-jar>
Cards Bean
<enterprise-beans>

<display-name>Cards</display-name>
Cards Bean
<ejb-name>Cards</ejb-name>
com.amity.cards.CardsHome
com.amity.cards.Cards
<ejb-class>com.amity.cards.CardsBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Bean</transaction-type>

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

Note that you have fully qualified class names (package name is appended to the class name) for the Home and Remote interfaces as well as the Bean's implementation class (ejb-class). There should be an example for your HelloWorld tutorial on constructing the ejb-jar.xml file.

Thank you for your reply
but here is my xml file:

<?xml version="1.0" ?>
<!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN" "http://java.sun.com/j2ee/dtds/ejb-jar_2_0.dtd">


<ejb-jar>

<enterprise-beans>
JBoss Hello World Application
<display-name>Hello World EJB</display-name>




<ejb-name>HelloWorld</ejb-name>
TestJBOSS.HelloWorldHome
TestJBOSS.HelloWorld
<ejb-class>TestJBOSS.HelloWorldBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Bean</transaction-type>



</enterprise-beans>

</ejb-jar>

apparently it seems to be correct ??

I have put all my files in TestJBOSS directory and in TestJBOSS/META-INF directory the ejb-jar.xml.

Thank you

[jonlee]

The ejb-jar.xml looks well-formed but from what you say, is in the wrong place.

In the Java source for your Bean classes do you declare the package as TestJBOSS?

e.g.

package TestJBOSS;

Your directory structure in the jar should be

|- META-INF
| +- ejb-jar.xml
|
|-TestJBOSS
+- HelloWorld
+- HelloWorldHome
+- HelloWorldBean

That is, the META-INF is from the root of the jar, not from TestJBOSS.

Thank you that was the reason of my error :)
