Got this working. Mainly just the issue of the encoding that was being used for
the response from the servlet. You need to be careful with the names of the
encoding as they can differ between operating systems. My recommendation would
be to always use UTF-8. My version of your servlet and client are below.
Hope this helps
Mark
SERVLET
=======
package test.encoding;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class Echo extends HttpServlet {
public Echo() {
super();
}
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doPost(request, response);
}
public void doPost(
HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("cp1255");
response.setContentType("text/html; charset=windows-1255");
PrintWriter out = response.getWriter();
String name = request.getParameter("name");
out.println(name);
