This happens because, the container is NOT able to find, the class correponding to the entry TestPackage.impl.TestSessionEJBBean in ejb-jar.xml. Please post your application.xml, ejb-jar.xml and jboss.xml

[shankar_rao]

i am posting my jboss.xml and appliction.xml and ejb-jar.xml


jboss.xml

<jboss>
 <enterprise-beans>
 <session>
 <ejb-name>TestSessionEJB</ejb-name>
 <jndi-name>TestSessionEJB</jndi-name>
 </session>
 </enterprise-beans>
</jboss>

application.xml

<application>
 <display-name>new test</display-name>
 <module>
 <ejb>test.jar</ejb>
 </module>
 <module>
 <web>
 <web-uri>test.war</web-uri>
 </web>
 </module>
 </application>

ejb-jar.xml

<ejb-jar>
 <enterprise-beans>
 <session>
 <description>Session Bean ( Stateless )</description>
 <display-name>TestSessionEJB</display-name>
 <ejb-name>TestSessionEJB</ejb-name>
 <home>TestPackage.TestSessionEJBHome</home>
 <remote>TestPackage.TestSessionEJB</remote>
 <ejb-class>TestPackage.impl.TestSessionEJBBean</ejb-class>
 <session-type>Stateless</session-type>
 <transaction-type>Container</transaction-type>
 </session>
 </enterprise-beans>
</ejb-jar>

After seeing the log, i guess your test.jar does NOT contain TestPackage.impl.TestSessionEJBBean. Are you sure that this class file is present in the jar. (P.S.: Be sure that you havent done a typo mistake in specifying the class name in <ejb-class> entry )

[shankar_rao]

my Test.jar containg TestPackage.impl.TestSessionEJBBean and even in my ejb-jar.xml the class name between <ejb-class > tag is also correct, where is the actul problem i am not getting......help me

[darranl]

Can you execute the command 'jar -tf jarname.jar' and show the output here.

Also are any classes referenced by your session bean, these may not be available at runtime.

[shankar_rao]

my bean is refering to ServiceLocator class where the lookup done,

after executing the given command i am posting the out put

D:\NewTest\Project1\src>jar -tf test.jar
META-INF/
META-INF/MANIFEST.MF
classes/common/
classes/common/EJBHomeFactory.class
classes/common/ServiceLocator.class
classes/TestPackage/
classes/TestPackage/impl/
classes/TestPackage/impl/TestSessionEJBBean.class
classes/TestPackage/TestAction.class
classes/TestPackage/TestActionForm.class
classes/TestPackage/TestSessionEJB.class
classes/TestPackage/TestSessionEJBHome.class
META-INF/application.xml
META-INF/ejb-jar.xml

[darranl]

The structure of the jar file you have created is not correct, you need to remove the 'classes' folder from the root of the archive. The output from jar -tf should be: -

META-INF/
META-INF/MANIFEST.MF
common/
common/EJBHomeFactory.class
common/ServiceLocator.class
TestPackage/
TestPackage/impl/
TestPackage/impl/TestSessionEJBBean.class
TestPackage/TestAction.class
TestPackage/TestActionForm.class
TestPackage/TestSessionEJB.class
TestPackage/TestSessionEJBHome.class
META-INF/ejb-jar.xml

(Also the application.xml should not be there but that is not related to the problem).

what shud be the dirctory structure of our working folder if we dont want to include classes folder in ***.jar file.

current work directory structure is

Newtest(root)
-->project1
/public_html/*.jsp and web-inf
--->project1/src/*.java and META-INF

-- /public_html/*.jsp and web-inf

-- classes/*.class

Is there any need to change the directory structure?

[darranl]

What are you using to create your jar file?

I use Ant to create all of my archives to the project structure is not too important, the jar ant target can be configured to pull contents from different locations correctly.
