Hi !

Running the application client is quite simple: right click the class containing
the main method, choose "Run" -> "Run as..." -> "Java Application".

Starting it from the command line is a bit more difficult. First of all you need
the client jar (you could extract it from the EAR file deployed to JBoss).
This command will start it:

java -cp %JBOSS_HOME%\client\jbossall-client.jar;MyAppClient.jar my.MainClass

where "my.MainClass" is the full class name of the class with the main method.

For a remote client: you simply have to change the property
"Context.PROVIDER_URL" to the remote host:

Properties props = new Properties();
props.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
props.setProperty(Context.URL_PKG_PREFIXES, "org.jboss.naming.client");
props.setProperty(Context.PROVIDER_URL, "jnp://my-remote-host:1099");
InitialContext initialContext = new InitialContext(props);

Hope this helps

PLZ NOTE: i used Xdoclet for creating Ejb......

temp.user.MyUser user=null;

try{

System.out.println("Calling EJB....\n<br>");

temp.user.MyUserHome muhome=temp.user.MyUserUtil.getHome();

System.out.println("Ccreating EJB....\n<br>");

/* mbtest=mbhome.create();*/

user=muhome.create(0, "dfhdfh", "62125049", "10","gr");

System.out.println(user.getId()+"<br>");

}catch(Exception exception)

{

System.out.println("Error :"+exception.getLocalizedMessage());

exception.printStackTrace();

}

The below is my output.............,
Calling EJB....

Hi !

in an app client you need to initialize the InitialContext in a different way
than you do it in a web client (there the server does it for you).

Full code should be:
Properties props = new Properties();
props.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
props.setProperty(Context.URL_PKG_PREFIXES, "org.jboss.naming.client");
props.setProperty(Context.PROVIDER_URL, "jnp://localhost:1099");
props.setProperty("j2ee.clientName", "MyClient");

InitialContext initialContext = new InitialContext(props);

Of course you have to change the provider URL for your remote server.

The "j2ee.clientName" is needed it you want to specify an environment naming
context (for EJB references specified in "application-client.xml"). You do not
need it if you look up the beans in the Global JNDI.

Hope this helps
