how to use parameter of one web context in another one?
Hey guys,
I have a web context which is a servlet
The other web context is a jsp
I also have a login page
In the login page after clicking the submit button the
control is passed to the servlet.
The login page passes the username and password
to the servlet
i have used doGet() method.
I simply want to retrieve the parameter present in url of the servlet and use this in the jsp.
How is this possible?
To make things clearer , here are the three pages:
1> Login.html:<HTML>
{<HEAD>
<TITLE>
First Media - DashBoard
</TITLE>
</HEAD>
<BODY>
<FORM METHOD=GET
ACTION="http://localhost:8080/Dashboard/Dashboard">//url for servlet
<IMG SRC="C:\dashboard\Picture1.png"
ALT="Unable to display picture" ALIGN="LEFT" HEIGHT="150" WIDTH="150">
<H3>
<CENTER>
LOGIN SCREEN
</CENTER>
</H3>
<P></P><P></P>
<P>
<H4>
<CENTER>First Media DashBoard Display</CENTER>
</H4>
</P>
<P>
<CENTER>
LOGIN ID 牋?
<INPUT TYPE="TEXT" NAME="userid">
</CENTER>
</P>
<P>
<CENTER>
PASSWORD 牋?
<INPUT TYPE="PASSWORD" NAME="userpass">
</CENTER>
</P>
<INPUT TYPE="SUBMIT" VALUE="SUBMIT">
</FORM>
</BODY>
</HTML>
Here's the servlet:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.util.*;
public class Dashboard extends HttpServlet
{
public void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException
{
res.setContentType("text/html");
PrintWriter out=res.getWriter();
out.println("<HTML>");
out.println("<HEAD><TITLE>FIRST MEDIA DASHBOARD</TITLE></HEAD>");
out.println("<FRAMESET ROWS=\"20%,80%\">");
out.println("<FRAMESRC=\"http://localhost:8080/Intro/Intro\">");//this is the url for the jsp
out.println("<FRAMESET COLS=\"20%,80%\">");
out.println("<FRAME SRC=\"c:/dashboard/MainNetwork.html\" NAME=\"mainframe\">");
out.println("<FRAME SRC=\"c:/dashboard/DisplayArea2.html\" NAME=\"displayframe\" SCROLLING=\"NO\">");
out.println("</FRAMESET>");
out.println("</FRAMESET>");
out.println("</HTML>");
}
}
Finally the jsp :
<HTML>
HEAD>
<SCRIPT LANGUAGE="JavaScript">
<!-- Hide from tired old browsers
function multiLoad(doc1,doc2) {
parent.mainframe.location.href=doc1;
parent.displayframe.location.href=doc2;
}
// -->
</SCRIPT>
</HEAD>
<BODY>
<IMG SRC="C:\dashboard\Picture1.png"
ALIGN="LEFT" WIDTH="80" HEIGHT= "80">
<A HREF="javascript:multiLoad('c:/dashboard/MainNetwork.html', 'c:/dashboard/DisplayArea1.html')">Network Log</A>
牋牋牋牋?
<A HREF="javascript:multiLoad('c:/dashboard/MainService.html', 'c:/dashboard/DisplayArea2.html')">Service Levels</A>
牋牋牋牋?
<A HREF="#" onClick=
"parent.location='../localhost_3A8080/Dashboard/Login.html';
window.location='C:dashboard/Login.html/default.htm';">LogOut
</A>
<H3>
<%
if (request.getParameter("userid") == null)
{
out.println("Welcome to dashboard");
}
else {
out.println("Hello," + request.getParameter
("userid"));
} %></H3>//code to try to greet the user by name
</BODY>
</HTML>
}
I know this is a long one, but guys, please help!!!
