First, read this article EJB invocations from a remote client using JNDI.

  1. You need a file called 'jboss-ejb-client.properties' in your classpath, the file needs the basic config to connecto to your jboss server, for example:

    remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false remote.connections=default remote.connection.default.host=localhost remote.connection.default.port = 4447 remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false

  2. Create the EJB Remote proxy

    Properties p = new Properties();
p.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
final Context context = new InitialContext(p);
final String appName = "YOUR APP NAME";
final String moduleName = "YOUR EJB MODULE NAME";
final String distinctName = "DISTINCT NAME";
final String beanName = "Your bean name";
final String viewClassName = ClienteDAORemote.class.getName();
String path = "ejb:" + appName + "/" + moduleName + "/"
        + distinctName + "/" + beanName + "!" + viewClassName;
Object o = context.lookup(path);
return (RemoteBean) o; //Cast to your remote interface

You need:

  1. A EJB with a remote interface
  2. A copy of the interface in your standalone client
  3. My properties files is for local and unsecured connections.

A example implementation is in this file. Its a example aplication that connects to a EJB Services, the entire repo is like your concept:

  1. A web application with JSF + PrimeFaces
  2. A EJB Bussiness Tier
  3. JPA with hibernate
  4. A standalone client
  5. EJB Web Services

Sorry for my bad english, cheers.
