    Calling an ejb of remote server from another ejb

    anamika Newbie

      hi all,

      I have the same requirement as specified in the thread
      http://www.jboss.org/index.html?module=bb&op=viewtopic&t=30024
      (calling a function of another ejb residing on another server)

      When i followed the thread, i got the result also. Now i can communicate between the ejbs.

      Again i have a problem. When i specify the context properties in the code, i am forced to specify the provider url of the remote machine for remote ejb communication. this makes some difficulty for generalization.

      I have specified the ejb reference of remote ejb in ejb-jar.xml and corresponding specification is there in jboss.xml like this

      ejb-jar.xml

      <ejb-name>AEJB</ejb-name>
      package.AHome
      package.ARemote
      <ejb-class>package.AEJB</ejb-class>
      <session-type>Stateless</session-type>
      <transaction-type>Container</transaction-type>
      <ejb-ref>
      <ejb-ref-name>ejb/BEJB</ejb-ref-name>
      <ejb-ref-type>Stateless</ejb-ref-type>
      package.BHome
      package.BRemote
      </ejb-ref>


      In jboss.xml


      <ejb-name>AEJB</ejb-name>
      <ejb-ref>
      <ejb-ref-name>ejb/BEJB</ejb-ref-name>
      <jndi-name>jnp://remote machine ip:1099/ejb/BEJB</jndi-name>
      </ejb-ref>



      At the time of deployment, server is identifying the external referenced ejb along with its path. So i need not give any url at context properties. Isn't it? but when i take the url specification from context properties, it is showing ejb not found exception. The exception is like this.

      javax.naming.NameNotFoundException: BEJB not bound
