Studio Creator, Socket Connection to External Device

Question

I am porting an existing & successful project from Netbeans 3.6 into Studio Creator to take advantage of some of the tools in the IDE for this application. The project requires opening a socket connection from the Server PC to an external Device (PLC) that is a Client on a static IP & a dedicated fixed port.
I am struggling to get past some security settings specific to AccessControlExceptions. Here is the code method being used to test:
public String button1_action() {
// Call methods to open connection, init streams, send command, and close connection.
try {
// Open Socket up and accept client connection
ipSocketObject = new ServerSocket(port);
bfSocket = ipSocketObject.accept();
// Establish Streams
is = new BufferedReader(new InputStreamReader(bfSocket.getInputStream()));
os = new PrintWriter(bfSocket.getOutputStream(), true);
System.out.println("Got to here...");
// Clear the msCounter #13002
os.println("r13002=0");
pattern = "13002";
do{ret=is.readLine();} while ((ret.indexOf(pattern)) ==-1);
is.close();
os.close();
bfSocket.close();
ipSocketObject.close();
} catch (IOException e) {
e.printStackTrace();
return null;
The Socket Connection is established, but the command string is not processed before Studio Creator generates a AccessControlException Fault. I have experiemented putting in a SocketPermission statement with out success.
Is anyone aware of some sample code I might be able to review for opening socket connections to clients in a Studio Creator Application? Please excuse this request if too rudimentary- I am an Industrial Controls guy by trade... :)

Sorry I know of no such application at this time, and unfortunately have not done socket work myself for many moons....
What JDK was your previous application written under? I googled for AccessControlException and socket and seems that sometimes accounts for some issues... you can also search for that combination in the forum advanced search and might find something there.... one more long shot suggestion based upon your statement "the command string is not processed".... could it be that you need to flush the stream...?
Sorry I don't have more to offer...
