I have a little program here where I try to create a server socket on the port 1234.

public class SocketTest {
public static void main(String[] args) {

    try {           
        ServerSocketConnection scn;
        scn = (ServerSocketConnection) Connector.open("socket://:1234");
    } catch (IOException e) {
        e.printStackTrace();
    }

}
}

I get a RuntimeException caused by the Connector.open() method.

UPDATE: Stack trace:

Exception in thread "main" java.lang.RuntimeException
at ej.ecom.io.Connector.open(Connector.java:61)
at SocketTest.main(SocketTest.java:12)

I tried to disable my antivirus and firewall and to put the creation of socket to a separate thread, but nothing changes. I feel I am making a basic mistake here. What am I doing wrong?

`ServerSocketConnection` is in `Java ME` isn't it ? – kaysush Feb 25 '13 at 16:29
Please show the stacktrace? Does `Connector` belong to a specific API? – home Feb 25 '13 at 16:29
Why not `ServerSocket()`? – Eng.Fouad Feb 25 '13 at 16:29
Yes, this is a specific API for a micro-controller: `ej.ecom.io.Connector`. Stack trace: `Exception in thread "main" java.lang.RuntimeException at ej.ecom.io.Connector.open(Connector.java:61) at SocketTest.main(SocketTest.java:12)` – Limbo Exile Feb 25 '13 at 16:32
Thanks for showing your main method awhole. It is very important that you exposed it instead of what is really needed -- the exeption message. – Val Feb 25 '13 at 16:35
I cannot use ServerSocket(). It is not included in the platform I am working on. – Limbo Exile Feb 25 '13 at 16:36
Added the stack trace to the post. – Limbo Exile Feb 25 '13 at 16:37
are you sure `"socket://:1234"` is right? – Visruth Feb 25 '13 at 16:42
Yes, it is from the documentation: http://docs.oracle.com/javame/config/cldc/ref-impl/midp2.0/jsr118/javax/microedition/io/ServerSocketConnection.html – Limbo Exile Feb 25 '13 at 16:45
