based on Brian's replies to my previous post, I wrote a java class, which send a HTTP request to servlet. It can be compiled but always threw an exceptions when I ran it. Can anyone help. Here is the code:

			

			

			package coreservlets;
			

			

			import java.io.*;
			

			import java.net.*;
			

			

			public class PostHTTP
			

			{
			

			public static void main(String args[])
			

			throws IOException, UnknownHostException {
			

			try
			

			{
			

			

			URL myURL = new URL("http://pc076/servlet/coreservlets.OffHold");
			

			URLConnection c = myURL.openConnection();
			

			c.setUseCaches(false);
			

			c.setDoOutput(true);
			

			

			ByteArrayOutputStream byteStream = new ByteArrayOutputStream(512);
			

			

			PrintWriter out = new PrintWriter(byteStream, true);
			

			String postData = "REASON_CODE=3B&RSPCODE=JSmith&CASENUM=NA795401&REPLY=123&SOURCE=XYZ&REPLYLINK=http://pc076/servlet/coreservlets.ShowParameters";
			

			out.print(postData);
			

			out.flush();
			

			

			String lengthString = String.valueOf(byteStream.size());
			

			c.setRequestProperty("Content-Length", lengthString);
			

			c.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
			

			

			byteStream.writeTo(c.getOutputStream());
			

			

			BufferedReader in = new BufferedReader(new InputStreamReader
			

			(c.getInputStream()));
			

			

			String line;
			

			//String linefeed = "
			

			";
			

			//resultsArea.setText("");
			

			while((line = in.readLine()) != null) {
			

			System.out.println(line);
			

			//resultsArea.append(linefeed);
			

			}
			

			}
			

			

			catch(IOException ioe) {
			

			// Print debug info in Java Console
			

			System.out.println("IOException: " + ioe);
			

			}
			

			}
			

			}
