My friend wrote a jsp script for me and I want to add a small function inside it.

Using <%=url%> variable I need to fetch the contents of that url and to print them to screen.

Can someone help me out?

<jsp:include page="<url>" flush="true" />

sorry, forgot to mention that this will only work if url is a resource in your current servlet context.

you can try this as well:
<%@ page import="java.net.URL,
                     java.net.URLConnection,
                     java.io.*" %>
<%
BufferedReader in = null;

try {
     URL myURL = new URL ("http://java.sun.com");
     URLConnection con = myURL.openConnection();

     in     = new BufferedReader(new InputStreamReader(con.getInputStream()));

     String s;
     
     // read in result
    while ((s = in.readLine()) != null) {
          out.println(s);
    }
} finally {
     // close stream
     try {
          if (in != null) {     in.close(); }
     } catch (IOException ie) {}
}
%>

One more thing, i'll need to pass some variables as parameters, something like:
    URL myURL = new URL ("http://java.sun.com?id=ID");

i want to use the id variables that is used though out the whole jsp.

i'm not sure i understand you correctly but if you have a variable ID used in your jsp, you can do something like:

URL myURL = new URL ("http://java.sun.com?id=" + ID);

i see id and pass are set becuase when i do:

         out.println(id);
I get the id.

But for some reason this doesnt work:
URL myURL = new URL ("http://www.script.cgi?id=" + id + "&pass=" + pass);

still trying to figure it out.
