Error getting values by getParameterValues() in a servlet from a jsp page

Hi, i cant recive in my servlet the values that a user write in some input text in the next page:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
     <form action="/ProyectoWeb/ServletPruebas" method="post">
          <table>
          <%
               for(int i = 0; i<10; i++){
%>
               <tr>
                    <td>
                         <input type="hidden" name="ps_oculto" value="<%=i%>">
                         <input type="text" name="ps_valor">
                    </td>
               </tr>
<%
          %>
          </table>
          <input type="submit" value="VALOR">
     </form>
</body>
</html>and this is the post method of my servlet:
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
          PrintWriter pw = response.getWriter();
          String[] pocultos= request.getParameterValues("ps_oculto");
          String[] valores= request.getParameterValues("ps_oculto");
          for(String oculto: pocultos){
               pw.println("ps_ocultos: " + oculto);
          for(String valor: valores){
               pw.println("ps_valores: " + valor);
          pw.flush();
          pw.close();
     }When i open the jsp page in my web server and do the sumit of its form i get the folow response of my servlet:
ps_ocultos: 0
ps_ocultos: 1
ps_ocultos: 2
ps_ocultos: 3
ps_ocultos: 4
ps_ocultos: 5
ps_ocultos: 6
ps_ocultos: 7
ps_ocultos: 8
ps_ocultos: 9
valores: 0
valores: 1
valores: 2
valores: 3
valores: 4
valores: 5
valores: 6
valores: 7
valores: 8
valores: 9
I can´t get the values that i put in the input text when i open the jsp in my web server, (before press the submit button i write text in the input text), i only get indexes 0,1,2,3 ... What is wrong?
Thanks in advance

My error its on the post method. I am getting the worg parameter for the values of my input text. I have change in the doPost the line
String[] valores= request.getParameterValues("ps_oculto");for this
String[] valores= request.getParameterValues("ps_valores");the code run perfect. Sometimes happens ...

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.http.*;

import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
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();
%>
</body></head></html>
But this produces one error, NullPointerException and dont shows me the real path.
Can anyone help me?
thanks

i have put this into one sevlet:
package utils.ticker;
import javax.servlet.ServletContext;
public class Edicion{
private ServletContext myContext;
public Edicion(ServletContext myContext) {
this.myContext = myContext;
public String getCC(){
return myContext.getRealPath("/");
and in the jsp page this:
<%@ page contentType="text/html; charset=iso-8859-1" language="java" import="java.sql.*"%>
<%@ page import="utils.ticker.*" %>
<jsp:useBean id="tick" class="utils.ticker.Edicion" scope="session"/>
<html><head><body>
<%=tick.getCC()%>
</body></head></html>
but appear this error in the tomcat.

Tomcat 6 Calling a Java Servlet from a JSP Page

Below is a very simple JSP Page that calls a Java Servlet. The question is given Tomcat security constraints, is it possible to call a servlet from a JSP and get the correct output without getting an error message? If so, how would you code the web.xml file?
c:\apache-tomcat-6.0.18

HelloWorldExample.xml is directly under localhost
The application would have this directory structure:

Once compiled, HelloWorld.class would be moved to the jservlets folder.
FYI, coding the above url-pattern results in:

The following url-pattern in the web.xml file permits the servlet to be executed but results in a null pointer exception:

Calling a servlet from a JSP page using the J2EE reference implementation

I have a JSP with an include tag as follows: <jsp:include page="servlet/ConnectionServlet" flush="true" />
When I use JRUN it works fine. I created an ear file and ported
the application to the J2EE reference implementation. When running the app under the J2EE reference implementation the ConnectionServlet is never called. I figured it must a deployment issue. I tried adding the ConnectionServlet.class file to the WEB-INF\classes file as servlet\ConnectionServlet.class but the JSP still can't find the servlet. Any ideas where I've gone wrong? TIA, Joe

I have a JSP with an include tag as follows:
<jsp:include page="servlet/ConnectionServlet"
flush="true" />Basically, WEB-INF/classes gets added to the classpath, so the directory structure under this folder should be identical to your package structure. If the ConnectionServlet.class is not actually in a package, then it should be directly in WEB-INF/classes (ie if "servlet" isn't actually the name of your package, don't use a WEB-INF/classes/servlet/" directory).
Then try taking out the "servlet" from your include tag, so you just have page="/ConnectionServlet" (not sure about the leading slash - try experimenting!)
if this doesn't work, try adding this to your WEB-INF/web.xml file:
<web-app>
<servlet>
<servlet-name>ConnectionServlet</servlet-name>
<servlet-class>your.full.package.here.ConnectionServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>ConnectionServlet</servlet-name>
<url-pattern>/ConnectionServlet</url-pattern>
</servlet-mapping>
</web-app>
Good Luck!

Do not know how to call Servlet from a JSP???

Invoking BPEL Process from a JSP Page 500 Internal Server Error

Hi,
I try to invoke a BPEL Process from a JSP Page and receive the following error. I just pasted the example from the Oracle PM Developer's Guide tutorial. Previously I deployed the CreditRatingService BPEL Process.
Can anyone help me, please?
D.
Here is a sequence from my JSP / and the error I get:
String ssn = request.getParameter("ssn");
if(ssn == null)
ssn = "123-12-1234";
String xml = "<ssn xmlns=\"http://services.otn.com\">"
+ ssn + "</ssn>";
Locator locator = new Locator("default","welcome1");
IDeliveryService deliveryService =
(IDeliveryService)locator.lookupService
(IDeliveryService.SERVICE_NAME );
// construct the normalized message and send to oracle bpel process manager
NormalizedMessage nm = new NormalizedMessage( );
nm.addPart("payload", xml );
NormalizedMessage res =
deliveryService.request("CreditRatingService", "process", nm);
Map payload = res.getPayload();
out.println( "BPELProcess CreditRatingService executed!<br>" );
out.println( "Credit Rating is " + payload.get("payload") );

Here is the solution:
Properties props = new Properties();
props.setProperty("orabpel.platform", "oc4j_10g");
props.setProperty("java.naming.factory.initial",
"com.evermind.server.rmi.RMIInitialContextFactory");
props.setProperty("java.naming.provider.url", "ormi://localhost/orabpel");
props.setProperty("java.naming.security.principal", "oc4jadmin");
props.setProperty("java.naming.security.credentials", "welcome1");
and several jars have to be added to the project:
Orabpel.jar , Orabpel-common.jar, oc4j*.jar,
%ANT_HOME%\lib\ant.jar;
%ANT_HOME%\lib\xercesImpl.jar;
%ANT_HOME%\lib\xml-apis.jar;
%AXIS_HOME%\lib\axis.jar;
%AXIS_HOME%\lib\axis-ant.jar;
%AXIS_HOME%\lib\commons-discovery.jar;
%AXIS_HOME%\lib\commons-logging.jar;
%AXIS_HOME%\lib\jaxrpc.jar;
%AXIS_HOME%\lib\log4j-1.2.8.jar;

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,,,

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.

Calling a servlet (in Tomcat) from a JSP Page (in Apache)

I have a web form in my JSP Page, which upon submits, will send the params to a servlet. The servlet will then process the request and send the results back to the calling JSP Page.
with that above senario, is there any way for me to reference a servlet (resides in Tomcat) from a JSP Page (resides in Apache HTTP Server)?
Thanks!

Apache HTTP server isn't a servlet/JSP engine.
Your JSP runs on Tomcat, right where the servlet does. Apache just forwards the request.

Help needed urgently to get the values from the jsp page.

hi,
I am badly stuck into this problem.Please help me and find a solution.
I am using ms-access and jsp.
my database structure is as given below:
m_emp_no | from_date | to_date | approver| status |
1002 | 22/9/2008 | 23/9/2008|1003 |pending
1004 | 29/9/2008 | 30/9/2008|1003 |pending
2044 | 15/9/2008 | 16/9/2008|3076 |pending
now this is exactly a leave apply scenario where a page is displayed and the user has to fill in the details to apply leave.then the approver has to approve that leaves so even, he should get the details in his account.
for example here 1003 has to approve leaves for 1002 & 1004.i am able to fetch data from database for the particular approver here is the coding:
<html>
<body>
<h2 align="center"><u><b><span style="background-color: #FFFFFF"><font color="#C0C0C0" face="Comic Sans MS">Leave
Approval Requests</font></span></b></u></h2>
<form method="POST" name="f1" action="update.jsp">
<%
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con=DriverManager.getConnection("jdbc:odbc:employee_details");
PreparedStatement p=null;
p=con.prepareStatement("select * from emp_leave_application where approver='"+username+"'");
ResultSet r=p.executeQuery();
while(r.next())

    <tr>
      <td width="100%" bgcolor="#999966"><b><u><%=r.getString(2)%></u></b></td>
    </tr>
</table>
<table border="1" width="100%" height="171" bordercolor="#FFFFFF" bordercolorlight="#FFFFFF" bordercolordark="#FFFFFF">
    <tr>
      <td width="100%" height="165" valign="top">

     <b>status</b>:<%=r.getString(5)%</p>
<p><b>Leave From</b> : <%=r.getString(2)%></p>
<p><b>Leave From</b> : <%=r.getString(3)%></p>
<p><b>Approve</b> : <select size="1" name="approved">
        <option value="Approved">Approved</option>
        <option value="Cancelled">Cancelled</option>        </select></p>
<%
con.close();
%>
<table border="1" width="100%" bordercolor="#FFFFFF" bordercolorlight="#FFFFFF" bordercolordark="#FFFFFF">
          <tr>
            <td width="100%" bgcolor="#999966">
              <p align="center"><input type="reset" value="Clear" name="B1">
              <input type="submit" value="Submit" name="B2"></td>
          </tr>
        </table>
        </td>
    </tr>
</table>
</form>
</body>
</html>{code}
this will display both the rows but when i try to retrieve the values into update.jsp using the code given below it gives me only one value which is the first 1002.
{code}approved=(String)request.getParameter("approved");
id=(String)request.getParameter("id");{code}
but i need both the values to be inserted into the update.jsp only then the approver will be able to approve the leaves individually with respect to the m_emp_no.
please help me out.
thanks in advance.

How to get the value retruned by java script function into my jsp page

Hai all,
I had a particular java script function which returns a date.
function getDate() {
var sDate;
// This code executes when the user clicks on a day in the calendar.
if ("TD" == event.srcElement.tagName)
// Test whether day is valid.
if ("" != event.srcElement.innerText)
//alert(event.srcElement.innerText);
sDate = document.all.year.value + "-" + document.all.month.value + "-" + event.srcElement.innerText;
document.all.ret.value = sDate;
var mahi=window.open("configurexml.jsp?xyz=document.all.ret.value")
return sDate;}
Now i want to display this particular date in my jsp page. can anyone tell me the correct approach or a sample code to diaplay this date in my jsp page.
<%@ page language="java"
import="javax.xml.parsers.*,java.io.*,org.w3c.dom.*"%><%@ page import="java.util.*" %>

<form name="f1">

Here where i am printing the date i had to get the value from the js function. how to do that. plz help me....

Are you talking about server-side java code (servlets/jsp) or client side (applet)? Given we are in the JSP forum I'll assume we're talking server side.
If so, you are making a common but fundamental mistake. JavaScript executes on the client, not on the server. If you want client data on the server it has to get there somehow. The simplest way to do this in JSP land is via HTTP. So... have your JavaScript code call a JSP (or servlet) and pass the value you want as a URL parameter. Of course this will also change the browser location, so if you don't want this to happen use a frame or iframe to capture your HTTP request.
For example:
Javascript....
function someFunction() {
return 1;
var value = someFunction();
location.href="somejsp.jsp?value=" + value;

Extracting a value from the j_security_check servlet into a JSP page

Hi Folks...
I have a problem as follows:
I log in into the web app, via my login.jsp page. Below is the code for the form that accepts the login information
<form method="POST" action="j_security_check">
<table cellpadding="0" cellspacing="0" border="0">
<tr>
    <td align="right">Username: </td>
    <td><input type="text" name="j_username"></td>
</tr>
<tr>
    <td align="right">Password: </td>
    <td><input type="password" name="j_password"></td>
</tr>
<tr>
    <td></td>
    <td><input type="submit" value="Login"></td>
</tr>
</table>
</form>Login is sucessful and I am brought to the 'studentstub.jsp' page. I would like the user name to appear on the 'studentstub.jsp' page. I used the following code in the 'studentstub.jsp' page :
<td><%= request.getParameter("j_username")%></td> but all I am getting is a null. The 'j_security_check' servlet is not exactly part of my package, but the glassfish app server. Is there anything wrong in the way I am extracting the information from 'j_security_check' ? Hope someone can advise, thanks.

Hi Folks..
I managed to get a reply from another forum and the suggested solution works. I am going to share it with everyone here.
I repalced this line of code:
<td><%= request.getParameter("j_username")%></td>with this:
<td><%= request.getRemoteUser()%></td>The 'getRemoteUser' method from HttpServletRequest returns the name of the authenticated user. I hope this information will be helpful to those caught in a simillar problem. Thanks.

I am getting an unknown error when trying to download a word document from mail to pages, any help

I am trying to download a word document from mail into pages and I keep getting an unknown error message, are there special settings for this? Any help much appreciated!

Not there aren't any special settings for this. You just use the Open In feature to save the document into Pages. You could have a font in the document that Pages doesn't like, maybe something that you copied and pasted from somewhere into the document that went corrupt. But there is nothing special about the way that you save a Word document into Pages. You save it like you save any document or file into a compatible app.

please elaborate your question.

Calling a Servlet from a JSP within Portal Portlet

We've created a JSP that calls a Servlet when the form is submitted. The servlet handles the request, does some basic processing and then forwards back to a JSP. This works fine outside of Portal.
What needs to be done in order for this to work within a portlet in Portal? We can get to the first JSP which is in a portlet, but as soon as we click the submit button (which tries to call the servlet) we get the basic page not found error. We need to click the button, go to the servlet and have the servlet forward back to our portlet.
I know this is not the ideal way of using Portal however...
Any ideas?
Thanks!

I was wondering is there any way I can call a servlet from jsp? There are two scenarios here
1 - if the jsp is currently being executed/evaluated on the server, then you can use <jsp:include> to "call" a servlet, or <jsp:forward> to cancel the jsp and transfer the control to the servlet.
2 - if the page is already loaded and running in the client, then the only way to call a servlet is making a HTTP request as from any other html page. Jave code does not execute on the client, so you have to use html/javascript at that point.
Calling a servlet within another servlet.
lets say one servlet maintains all dynamic html. I call this servlet from another servlet to create a dynamic page and then insert values into it.Close, but the standard pattern is the reverse of that. What normally happens is you retrieve the values to put in the page, and then call the page, passing in those values. Thats why often you get a servlet/actionbean getting called, which then forwards to a JSP to display the result. The servlet/bean loads all the values required into scope, and then the JSP presents the data.
