Socket doubt

[Girish Nagaraj]

Hi ,

I Am new to J2ME world.

I Have written a code (Socket Client) which asks for server and port name at the starting.
connects to that web server
makes the request
waits & gets the response
finally displays it...

When I entered valid server & port name I got this Exception:
java.lang.SecurityException: Target port denied to untrusted applications
at com.sun.midp.io.j2me.socket.Protocol.connect(+62)
at com.sun.midp.io.ConnectionBaseAdapter.openPrim(+52)
at com.sun.midp.io.j2me.socket.Protocol.openPrim(+108)
at javax.microedition.io.Connector.openPrim(+233)
at javax.microedition.io.Connector.open(+15)
at javax.microedition.io.Connector.open(+6)
at SocketMIDlet.run(+88)


Why Am I getting this Exception?
Is there any way to get around this?

Thanks in Advance...

ya it looks like you are trying to access a secured port with an untrusted application
There are two possible solutions according to me:

1,Sign your application with a digital signature from thawte or some site like that.

2,use another port that is not used by any os services or another applications.

The second one worked for me,but its stupid.
