[JBoss-user] [EJB/JBoss] - Re: Applet and EJB
Last time I did something similar to this was in a rush so didn't get a chance to look into the problem too deeply. I think my solution in the end was to sign all jars used by the Applet, so that included the JBoss jars.

[JBoss-user] [EJB/JBoss] - Re: Applet and EJB
I'm having a similar issue. When I invoke the create method on my bean, I get
an error (see below). I have signed my applet and I'm looking up the context
using the following code:
Properties jndiProps = new Properties() ;
String myServer = this.getCodeBase().getHost ();
jndiProps.setProperty("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory" ) ;
jndiProps.setProperty("java.naming.provider.url",
"127.0.0.1:1099" ) ;
jndiProps.setProperty("java.naming.factory.url.pkgs",
"org.jboss.naming:org.jnp.interfaces" ) ;
participantHome =
(DrawingParticipantSessionHome)PortableRemoteObject.narrow( new
InitialContext(jndiProps).lookup(
"ejb/chickenscratch/drawing/bus/ejb/DrawingParticipantSession" ),
DrawingParticipantSessionHome.class) ;
The server is hosted on my local machine (so 127.0.0.1 should be the correct
IP). I've also validated that the JNDI name I'm passing is correct.
Can anyone offer any suggestions?

Lets focus on one thing at the time. You need to make other changes in your configuration in order to use RMI over HTTP (just using HttpNamingContextFactory wont do it). First of all, I assume that the ip of your JBoss box is not 127.0.0.1 since you say yoi run it on another box. Still it seems that you are trying to connect to localhost when doing the JNDI lookup. Do you use ip or hostname in "myip"? Check your host files and check that you dont use a hostname that resolves to localhost(127.0.0.1).

[JBoss-user] [EJB/JBoss] - Re: Applet and EJB
Hi
Just so you know this is how I am naming props:
Properties jndiProps = new Properties() ;
Context context = new InitialContext(jndiProps);
jndiProps.setProperty("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory" ) ;
jndiProps.setProperty("java.naming.provider.url", myip:1099) ;
jndiProps.setProperty("java.naming.factory.url.pkgs",
"org.jboss.naming:org.jboss.naming" ) ;
jndiProps.setProperty("java.naming.factory.url.pkgs",
"org.jboss.naming:org.jnp.interfaces" ) ;
// The below statment is where the error is returned
TestAppletHome home = (TestAppletHome)PortableRemoteObject.narrow( new
InitialContext(jndiProps).lookup( "TestApplet" ),
TestAppletHome.class) ;
error: javax.naming.CommunicationExecption [Root execption is
java.rmi.ConnectionExecption: Connection refused to host 127.0.0.1; nested
execption is: java.net.ConnectionExecption: Connection refused: connect]
I have in the java.policy file:
permission java.net.SocketPermission "127.0.0.1:1098-", "accept, connect,
listen, resolve";
permission java.net.SocketPermission "127.0.0.1:1099-", "accept, connect,
listen, resolve";
and i still get this error.
if I make this change below as you suggested: HttpNamingContextFactory.
Am I using the correct class from the jar jbossall-client.jar?
jndiProps.setProperty("java.naming.factory.initial",
"org.jboss.naming.HttpNamingContextFactory" ) ;
where else should changes be applied?
Thanks for all the help...
Austin

A few ideas that might you in the right direction:
1. JNP
I am not sure how you set the naming props in your applet. Try this for now:
Properties env = new Properties();
| env.setProperty("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory");
| env.setProperty("java.naming.provider.url", "YourServerIP:1099");
| Context ctx = new InitialContext(env);
If you get this to work you can then change to get the IP of the server from
the applet instead of hardwiring it.
2. Port 1099
The deafult port for the naming service is 1099. You need to allowed to connect
to that port from the applet.(unless you have changed the port).
3. Signing the applet
Another way to get the applet to make those network connection outside the
sandbox is to sign it. That way you dont have to bother about the policy file.
If you want to deploy this solution over the Internet you probably want to
change the naming service to use the HttpNamingContextFactory to run it over
HTTP and get through all those fws.
