I'm running Solaris 2.4 with the last Beta Java software.
I declare some (extremely) mickey mouse classes like so:
public class TestClient extends java.applet.Applet {
int portnumber = 5046;
String host = "193.122.180.3";
DataOutputStream out;
DataInputStream in;
Socket socket;
public void meme()
{
System.out.println("we are here in meme with host: "+ host+ " and port: " + portnumber);
}
public void connect()
{
System.out.println("are we here");
try {
socket = new Socket(host, portnumber);
in = new DataInputStream(new
BufferedInputStream(socket.getInputStream()));
out = new DataOutputStream(new
BufferedOutputStream(socket.getOutputStream()));
} catch (UnknownHostException e){
System.out.println("an exceptception occurred: " + e.getMessage());
e.printStackTrace();
} catch (IOException e) {
System.out.println("an exceptception occurred: " + e.getMessage());
e.printStackTrace();
}
}
public static void main(String args[])
{
TestClient h;
h = new TestClient();
h.meme();
h.connect();
}
}
and I compile with "javac TestClient.java"
and run it thusly "java TestClient"
and I get this...
SIGSEGV 11* segmentation violation
si_signo [11]: SIGSEGV 11* segmentation violation
si_errno [0]: Error 0

I get a feeling that I've been here before. Is there a work-round? I need thi sfor a demo...so it might be back to good-old TCL if this doesn't work.
Cheers,
Roger.
