    Resource Adapter javax.naming.NamingException

    Greg Phillips Newbie

      Using JBoss 4.0.0, Java ee sdk 5.03.

      I'm trying to write a resource adapter, with the intention of being able to call some native (C++) code from a EJB.

      The EJB is in it's own project, and appears to be quite happy. I am using XDoclet, and so have included the following tags:

       * @ejb.resource-ref res-ref-name="eis/MySample"
       * res-type="com.riskaware.iwmdt.SampleConnectionFactory"
       * res-auth="Container"
       *
       * @jboss.resource-ref
       * res-ref-name="eis/MySample"
       * jndi-name="eis/ConnectorProj"
      


      This sorts out the ejb-jar.xml and the jboss.xml files for this project:

      ejb-jar.xml:

      <resource-ref id="ResRef_1">
       <res-ref-name>eis/MySample</res-ref-name>
       <res-type>com.riskaware.iwmdt.SampleConnectionFactory</res-type>
       <res-auth>Container</res-auth>
       </resource-ref>
      


      jboss.xml:

      <resource-ref>
       <res-ref-name>eis/MySample</res-ref-name>
       <jndi-name>eis/ConnectorProj</jndi-name>
       </resource-ref>
      


      Now, when the EJB tries to do a lookup:

       ctx = new InitialContext();
      
       ///////////////////////////////////////////////////////////
       NamingEnumeration ne = ctx.list("java:comp/env/eis");
       while(ne.hasMoreElements()){
       System.out.println(ne.nextElement());
       }
       ////////////////////////////////////////////////////////////
      
       ctx.lookup("java:/comp/env/eis/MySample");
      


      I get the following:

      16:06:24,685 INFO [STDOUT] MySample: javax.naming.LinkRef
      16:06:24,685 INFO [STDOUT] javax.naming.NamingException: Could not dereference object [Root exception is javax.naming.NameNotFoundException: eis not bound]
      16:06:24,685 INFO [STDOUT] at org.jnp.interfaces.NamingContext.resolveLink(NamingContext.java:971)
      16:06:24,685 INFO [STDOUT] at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:614)
      16:06:24,685 INFO [STDOUT] at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:643)
      16:06:24,685 INFO [STDOUT] at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:508)

      Now, in my resource adapter project, I have a ra.xml file that looks like this:

      <?xml version="1.0" encoding="UTF-8"?>
      <connector id="Connector_ID" version="1.5"
       xmlns="http://java.sun.com/xml/ns/j2ee"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/connector_1_5.xsd">
       <description></description>
       <display-name>ConnectorProj</display-name>
       <vendor-name>RiskAware</vendor-name>
       <eis-type>GDF</eis-type>
       <resourceadapter-version>0.1</resourceadapter-version>
       <resourceadapter>
       <resourceadapter-class>
       com.riskaware.iwmdt.SampleResourceAdapter
       </resourceadapter-class>
       <outbound-resourceadapter>
       <connection-definition>
       <managedconnectionfactory-class>com.riskaware.iwmdt.SampleManagedConnectionFactory</managedconnectionfactory-class>
       <connectionfactory-interface>com.riskaware.iwmdt.SampleConnectionFactory</connectionfactory-interface>
       <connectionfactory-impl-class>com.riskaware.iwmdt.SampleConnectionFactory</connectionfactory-impl-class>
       <connection-interface>com.riskaware.iwmdt.SampleConnection</connection-interface>
       <connection-impl-class>com.riskaware.iwmdt.SampleConnection</connection-impl-class>
       </connection-definition><transaction-support>NoTransaction</transaction-support><reauthentication-support>false</reauthentication-support>
       </outbound-resourceadapter>
       </resourceadapter>
      </connector>
      


      But, I don't have a .ds file. Do I need one of these to specify the jndi name for the RA? Or is there another problem here?

      Thanks,

          Yes you need a -ds.xml file. The rar is just a template for creating connectors,
          the -ds.xml file actually creates them.

          Also the jndi-name for a connector will be bound at java:eis/ConnectorProj
          not in the global namespace.
