    Problem looking up EJB session bean (Name not bound)

      Hello all,

      Can someone help me with a simple context lookup?

      I have a session bean deployed within JBoss 4.0.4 GA AS, JDK 5.

      My EJB3 code is as:

      @Stateless
@Local(AuthenticatorLocal.class)
@Remote(AuthenticatorRemote.class)
public class AuthenticatorBean implements Authenticator {


      The server started and deployed this session bean without any problem. Here is a snippet of the log:

      10:28:10,609 INFO [JmxKernelAbstraction] installing MBean: jboss.j2ee:ear=test.ear,jar=test.jar,name=AuthenticatorBean,service=EJB3 with dependencies:
      10:28:10,609 INFO [JmxKernelAbstraction] persistence.units:ear=test.ear,jar=test.jar,unitName=test
      10:28:10,625 INFO [EJBContainer] STARTED EJB: com.judots.test.AuthenticatorBean ejbName: AuthenticatorBean


      From an external client, my client is calling: 
      Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
p.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
p.put(Context.PROVIDER_URL, "jnp://localhost:1099");
_intialCtx = new InitialContext(p);

Object authenRef = _intialCtx.lookup("AuthenticatorBean");


      This code failed with the following exception:
      javax.naming.NameNotFoundException: AuthenticatorBean not bound
      at org.jnp.server.NamingServer.getBinding(NamingServer.java:529)


      I tried using various name like "Authenticator", "Authenticator/remote", "AuthenticatorBean/remote" but ended up with the same "'name' not found error. Can some one please help?

      Thanks

          Try using AuthenticatorLocal.class.getName() for local interface and AuthenticatorRemote.class.getName() for remote interface.

            I think the problem I am having is relating to the way I packaged my ear file.

            When I unpacked the ear and deployed only the jar file, I had no problem looking up the remote interfaces.

            I would greatly appreciate if someone can help clarifying what I need in my ear file. O'Reilly's Enterprise JavaBeans 3.0 does not seem to address this at all.

            Here is the structure of my ear file:

            test.ear
 test-ds.xml
 test.jar
 META-INF
 application.xml
 MANIFEST.MF


            My application.xml contains the following: 
            <?xml version="1.0" encoding="UTF-8"?>
<application>
 <display-name>test</display-name>
 <description>Test Project</description>
 <!-- The EJB-JAR -->
 <!-- TODO: JBoss needs 'ejb' element but the spec requires 'persistence' -->
 <module>
 <!--
 <ejb>test.jar</ejb>
 -->
 <persistence>test.jar</persistence>
 </module>
</application>


            And my test-ds.xml is as followed: 
            <?xml version="1.0" encoding="UTF-8"?>
<datasources>
 <local-tx-datasource>
 <jndi-name>testDS</jndi-name>
 <connection-url>jdbc:sqlserver://localhost:1814;databaseName=test;selectMethod=cursor;</connection-url>
 <driver-class>com.microsoft.sqlserver.jdbc.SQLServerDriver</driver-class>
 <user-name>***</user-name>
 <password>***</password>
 <transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation>
 <min-pool-size>25</min-pool-size>
 <max-pool-size>100</max-pool-size>
 <blocking-timeout-millis>5000</blocking-timeout-millis>
 <idle-timeout-minutes>15</idle-timeout-minutes>
 <prepared-statement-cache-size>75</prepared-statement-cache-size>
 </local-tx-datasource>
</datasources>


            I think my test-ds.xml is OK because it worked with plain jar deployment. What else missing in my application.xml file?

            Thanks for your help.
