Implement a MIDlet that gets invoked when a SMS is sent to port 50000
Question
I want to create a MIDlet which automatically starts using push registry function
PushRegistry.RegisterConnection("sms://:50000", this.getclass().getname(),"*");
Following is the code which I have come up with, and cannot find the problem with it as it is not responding in any way to any message.
P.S. I am aware of the fact that dynamic registration requires me to first run the app once.
public class Midlet extends MIDlet implements CommandListener,Runnable {
private Display disp;
Form form = new Form("Welcome");
Command ok,exit;
public void startApp() {
String conn[];
exit= new Command("exit",Command.CANCEL,2);
ok= new Command("ok",Command.OK,2);
form.addCommand(ok);
form.addCommand(exit);
form.setCommandListener(this);
conn = PushRegistry.listConnections(true);
disp=Display.getDisplay(this);
disp.setCurrent(form);
form.append("Midlet");
form.append("Press OK to register sms connection");
}
public void pauseApp() {
}
public void destroyApp(boolean unconditional) {
notifyDestroyed();
}
public void commandAction(Command c, Displayable d) {
if(c.getLabel().equals("exit"))
{
System.out.println("exit pressed");
destroyApp(true);
}
if(c.getLabel().equals("ok"))
{
String[] cn;
cn=PushRegistry.listConnections(true);
form.append(""+cn.length);
for(int i=0;i<cn.length;i++)
{
form.append(cn[i]);
}
Thread t = new Thread(this);
t.start();
}
}
public void run() {
try {
PushRegistry.registerConnection("sms://:50000",this.getclass().getname, "*");
} catch (IOException ex) {
ex.printStackTrace();
} catch (ClassNotFoundException ex) {
ex.printStackTrace();
}
}
}
La solution
Your code worked when I replaced this line PushRegistry.registerConnection("sms://:50000",this.getclass().getname, "*");
with PushRegistry.registerConnection("sms://:50000",<actual name of the class>, "*");
