Hi,
I was trying to connect to a servlet through an applet.I created an htm=
l
page with two frame.At the top frame the applet was embedded and in the b=
ottom
frame the servlet was server side included.I used the GET method to
communicate to the servlet.So in the init method of the applet I added th=
e
following code to get a connection to the servlet.And pass information th=
rough
the URL.
////////////////////////////////////////////////////////
String
servletLocation=3D"http://172.100.8.213:8080/servlet/serv.HelloWorldServl=
et1?LastName=3D'Jones'";
try{
testServlet =3D new URL( servletLocation );
}
catch (MalformedURLException e){
}
try{
servletConnection =3D testServlet.openConnection(); =
}
catch(IOException e){
}
///////////////////////////////////////////////////////////////////////
The code of the servlet is shown below,where I tried to get the informati=
on
passed from the applet
public class HelloWorldServlet1 extends HttpServlet {
=
public void doGet (HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
{
PrintWriter out;
res.setContentType("text/html");
out =3D res.getWriter();
String name=3Dreq.getParameter("LastName");
=
out.println("<html>");
out.println("<head><title>Hello World</title></head>");
out.println("<body>");
out.println("<h1>LastName=3D"+name+"</h1>");
out.println("</body></html>");
}
}
/////////////////////////////////////////////
The output is showing a null value for the name.Is it wrong to send the
information to the servlet from the init method.Can you suggest some othe=
r
method or simple code for the communication.
regards,
Rakesh.
