Unable to call another program in servlet

[Former Member]

Hi,

I'm developing a Java program in Netweaver. It is a servlet program. External server will call this servlet program to pass the value in and then i use the value and pass to a stateless session bean. But now i'm required to make some change but in certain condition, it will use the value and pass to another servlet in another server.

So i had changed my code as below.

	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		String xml_response = "";
		String msg = request.getParameter("message").trim();
		FileReader fread = null;
		BufferedReader bread = new BufferedReader(new FileReader("D:\\filter.txt"));
		String line;
		ArrayList moList = new ArrayList();
		
		while((line = bread.readLine())!=null)
		{
		 	String[] moNum = line.split(",");
		 	for(int i=0; i<moNum.length;i++)
		 	{
		  		moList.add(moNum<i>);
		 	}
	   }
	   bread.close();

           try {
			xml_response = "700";
			response.setContentType("text/html");
			PrintWriter out = response.getWriter();
			out.println("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
			out.println("<status>" + xml_response + "</status>");
			out.close();

                        if (moList.contains(ms)) {
				response.sendRedirect("http://192.168.1.1:50000/adapter/msgtext?sms=" + sms + "&moid=" + mo_id + "&msisdn=" + msisdn);
                        } else {
                          .................
                        }
           } catch ......

I have a xml to response to the server that pass me the value. Need that to inform them i had received the msg. So now i not sure the error is it caused by the XML part. I already close it but when i try to run this i get this error message.

Appreciate if anyone can help. I tried to google and find the error message that is given but unable to find it. What i think of is the XML that cause error. Any idea for this?

Thanks.

Solved.

The XML caused the problem. I need to include the XML in the if statement instead of outside.
