Problem creating a EJB from third party into NWDS

Question

Hi everybody:
I´m trying to create a EJB from a third party software (jar file). I imported the jar file into my EJB Module (Properties->Java Build Path->Library), selected the EJB candidate and wrote the ejb-jar.xml according to the vendor's instructions in order to define home and remote interfaces.
When I deploy my application (containing the EJB Module), I got this error from the server:
java.rmi.RemoteException: Cannot deploy application sap.com/TestEjbApp.. Reason: Incorrect application sap.com/TestEjbApp:Bean AccountLocateBean: the ejb-class must implement, directly or indirectly, the javax.ejb.SessionBean interface. EJB specification 7.10.2.; nested exception is: com.sap.engine.services.deploy.container.DeploymentException: <--Localization failed: ResourceBundle='com.sap.engine.services.deploy.DeployResourceBundle', ID='com.sap.engine.services.ejb.exceptions.deployment.EJBDeploymentException: Incorrect application sap.com/OlivierTestEjbApp:Bean AccountLocateBean: the ejb-class must implement, directly or indirectly, the javax.ejb.SessionBean interface. EJB specification 7.10.2.
at com.sap.engine.services.ejb.deploy.verifier.Verifier.check(Verifier.java:66)
at com.sap.engine.services.ejb.deploy.DeployAdmin.generate(DeployAdmin.java:253)
at com.sap.engine.services.ejb.EJBAdmin.deploy(EJBAdmin.java:2133)
I used the same jar in another application server (Sun Open), mounted teh EJB and it ran perfect. Additionally I checked the class and it has the correct "implements javax.ejb.SessionBean" statement in the code.
Do you have any idea about it?
Thanks
Regards
Olivier

Hi Amol:
Thanks for your answer, Let me explain a little more what I'm doing:
The third party software is a jar file that contains three classes:
com.account.AccountLocateSessionBean (Remote Interface)
com.account.AccountLocateSessionBeanHome (Home Interface)
com.account.AccountLocateBean (EJB class)
This 3 classes are EJB 2.0 complaint and were tested in other J2EE container (Sun Open). I want to deploy this EJB into SAP Was J2EE 6.40 server (SP14). In my last post I wrote what I did in order to create de ejb-jar.xml into NWDS. This file looks like:
<?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>
    <description>EJB JAR description</description>
    <display-name>EJB JAR</display-name>
    <enterprise-beans>
        <session>
            <ejb-name>AccountLocateBean</ejb-name>
            <home>com.account.AccountLocateSessionBeanHome</home>
            <remote>com.account.AccountLocateSessionBean</remote>
            <ejb-class>com.account.AccountLocateBean</ejb-class>
            <session-type>Stateless</session-type>
            <transaction-type>Container</transaction-type>
        </session>
    </enterprise-beans>
</ejb-jar>
Then, when I build the ear file (This is a Enterprise application that contains my EJB Module) and try to deploy this ear file into SAP Was J2EE 6.40 server (SP14) I got the exception wrote in my last post.
Thanks for your help
