Can a servlet make a jsp page display?
A total newbie question. If I do this in a servlet:
RequestDispatcher rd = request.getRequestDispatcher( "/index.jsp" );
rd.forward( request, response );
- does index.jsp in the context path actually display?
If yes, what's wrong if it doesn't display?
Yes, you can pass control from your servlet to the JSP page that way. If it isn't displaying, then you should show us the error message you are getting so that we can help you more effectively.

How do I Display a string from a servlet into a JSP Page???? NEED HELP!!!!
Hi guys,
How do I Display a string from a servlet into a JSP Page...
Ive tried so many bloody things!.....
Simply.
I get text from JSP. The servlet does what ever it does to the string.
Now. Ive create sessions and bean things,.... how the hell do I display it in a text box... I can display on the screen.. but not in the text box.!!!
please help!!!hmmm, I dont really like using JSP programming, u should be using JAVA..
the way to do it is:
Call and cast to the bean like this:
<%@ page import="beans.*" %>
<% //cast to bean get request create object
userNameBean u= (userNameBean) request.getSession().getAttribute("userNameBean");
then... all you do is call it like this:
<input type="text" name="firstName" value="<%= u != null? u.getFirstName(): "" %>">
this is the real programmers way,,,

Problem for getting the real path using one servlet and one jsp page
I have one tomcat machine and several virtual domains. Eahc virtual domain has one realpath in the disc.
I am using one servlet and one jsp page for using this servlet.
my purpose is to load, using the servlet , the real path for the domains (eahc domain has its path).
for this i make this:
the servlet code is this:
package utils.ticker;
import java.io.*;
import java.io.File;
import java.io.IOException;
import java.net.*;
import java.util.*;
import java.text.*;
import javax.servlet.*;

import javax.servlet.ServletResponse;
public class Edicion extends HttpServlet{
public Edicion() {
public String cc(){
ServletContext myContext= getServletContext();
String abspath = myContext.getRealPath("/");
//here i want to return the real path
return abspath;
public static void main(String args[]){
and the jsp page is:
<%@ page import="utils.ticker.*" %>
<jsp:useBean id="tick" class="utils.ticker.Edicion" scope="session"/>
<html><head><body>
<%
tick.cc();

But this produces one error, NullPointerException and dont shows me the real path.
Can anyone help me?
thanksi have put this into one sevlet:

Ive just learned that i can use loadjava to load jsp pages into the database.
Ive just learned that i can use loadjava to load jsp pages into the database. How is that possible. How can someone go to my lets say, index.jsp page and actually see it if its inside the database? What authenticates it? Where would you set the parameters to tell http(apache) to look inside the db for the pages?
Any ideas?Thanks for the reply. If I put the file on the database, does it have to be in a particular location? I've put it on the database server, launched sql*plus (as APPS) and ran the following:
execute dbms_java.loadjava('-v', 'ZebraGetPrinterFromXML.class');
PL/SQL procedure successfully completed.Then when I try to run a process that uses this I get this:

How can I make the jsp pages not displayed by using the navigation class?
I'm right now implementing a function on my program GUI . It's like whenever I click "STOP THE SERVER" button on the main page, I need those jsp pages relates to the server running to be not displayed, even by directly type in the URL(that's just stay in the main page), How can I do that? I heard that a navigation class might do it, but I'm not sure how. It might be great if some experts could help me!! Thanx a million !!

How to make a JSP page always come from servlet
Hi!
Although ihave used "<%@ page session="true" %>" in some of my JSP pages, it can be accessed by just typing in the URL of that page in the browser.(After invalidating the session)
I want that page to be accessed only if it is called theough a servlet..
Plz help geeks!
otherwise my applica'n is in for a serious hack!
thankx in advance
javedSet a flag (attribute) in session in your servlet, then forward/direct the request to your jsp. Test for that flag in your jsp, if it is not there then show error message to the users.
Like this,
String flag=session.getAttribute("isComingFromServlet");
if(flag==null || !flag.equals("true")) {
out.print("<h1>Sorry, you can't access this page !!!</h1>");
return;
} -
Can I include a servlet in a jsp page?
Is there anyway to include a Servlet in JSP page?
What exactly do you want to achieve? And are you using 'include' in the generic sense or in the [JEE sense|http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/RequestDispatcher.html#include(javax.servlet.ServletRequest,%20javax.servlet.ServletResponse)]?
By the way, behind the scenes, a JSP gets compiled into a servlet.

How include a Servlet into a JSP page?
Hi!!
I need make a combobox with a servlet and place its result into a jsp page.
The servlet is in a package, but when i do: <jsp:include file="sic.view.servlet.ComboServlet" />
tell me that "file attribute isn�t a valid attribute name"
whow can i do to make the combobox whit the servlet and include this into the jsp page??
Thanks!!
PD: Sorry my pour English...Servlets should be mapped to a URL, then you access the servlet via that URL.
The servlet mapping is done in the web.xml (in WEB-INF/ directory of your web application)
<servlet>
<servlet-name>
Combo_S
</servlet-name>
<servlet-class>
sic.view.servlet.ComboServlet
</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>
Combo_S
</servlet-name>
<url-pattern>
/combo
</url-pattern>
</servlet-mapping>Then you would use:
<jsp:include file="combo" />
to include it.
Make sure the class file gets put in the right package under WEB-INF/classes/ -
Include a Servlet into a JSP page
Hi guys,
When i try to include a Servlet into my JSP, the execution of the JSP stops...Somebody know why???Hi guys,
When i try to include a Servlet into my JSP,the
execution of the JSP stops...Somebody knowwhy???
No, and do you know why ? Bcos including a
servlet
in
a jsp doesnt stop the execution of the jsp. Sotell
us that you tried to do, post some relevant
code,
for us to help you.
ram.<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@page buffer="500kb"%>
<html>
<head><title>JSP Page</title></head>
<body>
<jsp:include page="/showCryptValue"
ptValue" flush="true" />
asdfasdfasdfasdfasdf
</body>
</html>
that's the source code....do you have any idea????
Thak's a lottttFrom linxpda:
1) setting the flush="false" parameter for thejsp:include tag?
Here is the problem that I, and perhaps linxpda,
think you have:
You get an exception in the servlet.
You have already written to and flushed the response,
therefore you can not see the exception on your
screen (seeing the exception on screen requires a
send redirect to the error page, which can't happend
when the response is already committed).
The exception that is occuring MAY be alreay written
in your logs, take a look.
To see the problem on screen so as to be able to
identify it, make sure your include tag DOES NOT
flush the buffer. That means change
<jsp:include page="/showCryptValue" flush="true" />
to
<jsp:include page="/showCryptValue" flush="false" />Hi!
No even setting flush false or true it works...If somebody have done this before tell me how have you did....If you can post your code!

Can you open a second jsp page as popup/new window?
Hi all gurus!
I have a question regarding popups/new windows in an iview application. Instead of starting with a question let me instead describe what I want to do.
We have a jsp page that presents a search and then the search result in a table where one column is "clickable". When the user clicks a cell a server round trip retreives data specific for that cell value. This is standard functionality and already fixed so here is what differes: we want a new jsp window to open like a popup, with the data retreived from the server round trip and at the same time the first page with the table shall still be there so that you just can close the popup and click the next cell which creates a new server round trip and a new jsp popup and so on.
My solution which doesn't work yet: In application "a" I have a JavaScript for the clicked cell which opens another iview application "b" in a new window, by window.open("navurl_to_the_iview"), and that works fine.
At the same time the value of the clicked cell is written to the data bean and the bean is put in the http session (since component session does not reach between applications).
The second iview "b" retreives the bean from the http session and fills the jsp page with data.
Here is now the problem: no data is displayed and this because the iview "b" retreives the bean BEFORE iview "a" has been able to put the bean/value into the http session. How do I know this for sure? Simple, if I do a refresh of iview "b" the value is displayed.
I could do a JavaScript that recursively checks if the value in the bean is null or not but then I have to do a method that retreives the bean from the http session each time.
This could work but I wonder if this is the most simple solution. So my question for you gents and madams is: do you know of a more simple solution?
Best regards
Benny Lange
Edited by: Benny Lange on Oct 6, 2009 11:33 AMHi you all.
In this case the solution was to pass the id in the url to the second iview and let that iview use the id to retreive data from the backend system.
But I still think the question is interesting, if it's possible to open a second jsp window after a server round trip and still have the first one open.
All the best

Tomcat 4.1.24 : JSP page displayed blank in browser
Hi,
I am facing a problem where a blank screen is displayed to the user in browser even though the JSp page is getting executed successfully on my Tomcat server. The application and catalina logs show no errors / exceptions, still blank screen is displayed to the user sometime. If the user clicks on browser back button, the request is processed again and the page content is displayed properly.
I am using JDK 1.4.2_09 with Tomcat 4.1.24 on Windows 2003 server.
Is it to do with JSP:Forward mechanism? I forward the request from one JSP to second JSP and this second JSP gets executed on server but shows blank screen.
Requesting for help.
Thanks in advance.
