Ok,
Your servlet should have a stream that will connect to servlet2. Then
you can parse that stream from your servlet.
ex:
Servlet1.java
MyConnection c = new MyConnection;
String RS = c.connect();
parse(RS);
....
MyConnection.java
URL u = new URL("servlet2 url");
URLConnection connection = u.openConnection();
connection.setUseCaches(false);
BufferedReader inputStream = new BufferedReader(new
InputStreamReader(connection.getInputStream()));
String line = inputStream.readLine();
while (line != null) {
buffer.append(line);
line = inputStream.readLine();
}
inputStream.close();
return buffer.toString();
hope this will help you
