I don't have the slightest clue what this approach entails. None.

Okay. So you are using an HttpURLConnection. Good.

Huh. What? How? What are you doing? Did you actually try this? No you are making wild guesses.

To actually do it rather than making wild and incorrect guesses about what might happen if you actually do anything?

You never explained your first implementation.

here is my applet code.

checkJavaScriptEvent obj=new checkJavaScriptEvent();

obj.start();

URL currentPage=getCodeBase();

String protocol = currentPage.getProtocol();

String host=currentPage.getHost();

int port=currentPage.getPort();

String urlSuffix="/PrintAppletCSharp/Default.aspx";

System.out.println("currentPage : " + currentPage + "\nprotocol : " + protocol + "\nhost : " + host + "\nport : " + port);

try {

URL dataUrl=new URL(protocol,host,port,urlSuffix);

URLConnection connection=dataUrl.openConnection();

connection.setUseCaches(false);

//connection.setRequestProperty("header", "value");

System.out.println("Got a connection");

//BufferedReader in=new BufferedReader(new InputStreamReader(connection.getInputStream()));

DataInputStream in = new DataInputStream(connection.getInputStream());

//byte[] b=new byte[20];

//int count =is.read(b);

System.out.println("After Getting a connection");// + count + " : " + b.toString());

String line="";

while(!line.equals("EndScriptPrint"))

{

line=in.readLine();

if(!line.equals("StartScriptPrint") && !line.equals("EndScriptPrint"))

fromServer+=line + "\n";

System.out.println("Line " + line);

}

FileWriter fw=new FileWriter("t.txt");

fw.write(fromServer);

fw.close();

Process p=Runtime.getRuntime().exec("notepad.exe t.txt");

repaint();

} catch (Exception ex) {

ex.printStackTrace();

}

Java uses the stream classes. What all others do I don't know. If you don't know what kind of data you're getting from your own services, we are certainly not the ones to ask.

So what? It could be a COBOL applet for all that matters. It rather looks like you don't understand *what* is sent. How it's sent doesn't matter.
