    How do I access EJBs remotely

     

    JNDI Properties

     

    Using a Provider URL

     

    You'll need a jndi.properties on the remote client which looks like this:

     

    #jboss JNDI properties
    java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
    java.naming.provider.url=jnp://localhost:1099
    java.naming.factory.url.pkgs=org.jnp.interfaces
    
    ### The TimedSocketFactory connection timeout in milliseconds (0 == blocking) 
    jnp.timeout=0
    ### The TimedSocketFactory read timeout in milliseconds (0 == blocking) 
    jnp.sotimeout=0
    

     

    Replace localhost with the jboss's DNS name or IP and if you have configured the jboss naming service for some other port, you will need to change the 1099 to reflect that port. You can also provide a delimited list for the provider URL like java.naming.provider.url=jnp://192.168.99.1:1100,192.168.99.2:1100,192.168.99.3:1100

     

    The last two timeout properties are optional, defaults are zero.

     

    Using Naming Discovery

     

    If you would like to use Naming Discovery (appropriate for a clustered environment), you will need a jndi.properties on the remote client which looks like this:

    #jboss JNDI properties
    java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
    java.naming.provider.url=
    java.naming.factory.url.pkgs=org.jnp.interfaces
    jnp.partitionName=YourPartitionName
    

     

    This configuration presupposes that your network is set up in such a way that multicast traffic is visible between your remote client and the EJB-serving JBoss instance.  (e.g. the machines are on the same subnet)  It also assumes that you have configured your serving JBoss instance to be a member of the

    YourPartitionName

    partition.

     

    Interfaces

     

    You must use Remote and RemoteHome interfaces.

     

    Security

     

    If you have configured a secure realm, you will need to set up a JAAS security login to the EJB tier.
