Byte Problems

[Rmstn1580]

I'm attempting to create a program that acts as a server, and when it gets connections from a client, it sends the text and the client opens a new window and displays the text. I got it to connect and send and everything, but the text says "84" instead of what it's supposed to say. I don't know if that's a problem with the bytes or what. Well, here's my code. I've taken out a few of the non-needed classes.

Server code

        add(x);
        
        pack();
        setVisible(true);
    }
}

the problem is with the following code..

byte i = dis.readByte();
Byte b = new Byte(i);

Byte.toString() method will convert the the byte value to String. Also readByte() will read only one byte.You can do the following

byte b [] = new byte[1024] //read one kb
int i = 0;
StringBuffer sb = new StringBuffer();
while ((i=dis.read(b,0,1024))!=-1) {
sb.append(new String(b,0,i));
}
Info info = new Info(sb.toString());

Thanks a lot! It worked. I can't believe I didn't think of that O_o
