in this website URL....it sent request to html instead ? how could it work? i thought you could only send format to jsp, asp, php, or etc..could html page also process form request?
<FORM class=cl action=/de/toolbar/suchergebnisse.html><INPUT name=_charset_ type=hidden value=UTF-8>
I want to understand how is it possible to send data (image + text) along a single form. Here is my code:
<form method="post" action="updateAccount"
encType="multipart/form-data">
<input type="file" name="file" value="Select image ..." /> <input
type="submit" value="Start Upload" /> <br>
<textarea rows="8" cols="54" name="about">Yes
<form name="form" method="Get" action="MetadataSelect" >
<input type="checkbox" dir="rtl" ID="CheckBox2" value="check" onclick="All(this,'all','_chk');">
<display:table name="requestScope.list" cellspacing="5" pagesize="20" style="simple"
decorator="checkboxDecorator" form="form" requestURI="MetadataSelect" export="true"
excludedParams="_chk">
<display:column property="checkbox" title="اختر" value="${id}" >
</display:column>
[Code]...
The problem is the the request did not give any value then the a variable all is null
In one jsp page, I submit a form with a message body with following html code (which is store in "MsgBody" in my request)
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
[code]....
But when I submit my form, I received in my servlet a parameter "MsgBody" without several tag like <html>/<body> ... do you know this behavior, by default tag are delete ?
public String execute(Map params, HttpServletRequest request, HttpServletResponse response) throws Exception {
String MsgBody = request.getParameter("MsgBody");.
I use Tomcat 7, maybe a tomcat behavior can influence for this tag loose in request param ?
i have this code
////////////////////////////////////////////
<form name="myform" action="http://localhost:8080/EASYPAY.COM/faces/newxhtml.xhtml"method="post">
amount
<input type="text" name="amount"value="">
<input type="submit" >
</form>
[code]...
when i submit the html form the value of amount does not appear in the second jsf page new.xhtml what might be the problem
I have a very simple HTML form with a textField for a name, and add button to add the name to a MySQL database, and a sort button to sort the names in the database and display them. I almost have it working, however when I hit the "sort" button; I get the message that appears after a user clicks the add button along with the sorted list of names. It looks like this:
Please go back and add a name or sort.

My servlet code:
import java.io.IOException;

I am having an issue with retrieving "grouped" data from HTML form to servlet. I will describe the scenario below.
In companies, they record the salary of the employees once a month.When they record it, they do not do it by visiting each an every employees personal "profile" (or whatever according to the system). Instead what they do is apply the salaries of all of them in one page.
To do the above thing they prefer excel like tabular sheets. Now, I have a html form, where the form content is a table. One row is dedicated to a one employee.
Below is my form.
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
[Code] .....
As you can see, I have wrapped every row with a `<tbody>`. The `value` attribute of the `<tbody>` will contain the employee id. Once the form is submitted, the below servlet will capture it.
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
[Code] .....
What I was trying is get the `value` attribute of `<tbody>` (so I can identify the id of the employee) and get the data inside that `<tbody>`. However this didn't work, because I ended up with `NullpointerException` because it failed to read the `<tbody>` value.
So, how can I pass the data from table to servlet where it can clearly understand that one row is representing data belong to a one employee? If this is not the way to do it, I am also open for other methods.
For a class assignment I have to write a JSP program that will get the name and gender from a simple HTML form and then provide feedback to the user such as "Enter your name" if they leave that field blank. The HTML form has a textField for the name and two radio buttons for male and female, plus a submit button. We covered JSPs only briefly so along with being a Java newbie, JSPs are pretty foreign. I had written the same program as a servlet so I attempted using the similar code for the JSP. I'm using switch to get the gender from the radio buttons but that doesn't seem to work as I keep getting the response "Please select your gender".
My JSP code:
<%@ 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">
<%@ page import="java.util.ArrayList" language="java"%>

I have the following questions:
1. Does a GET HTTP request contain a request body? If yes what is contained in it? Are the request headers also part of the request body?
2. Is it possible to send a byte array as part of the GET request in its body?
3. Is there a size limitation on the data that can be sent via a GET request?
import java.util.Scanner;
public class Exercise1{
public static void main(String[] args) {
String employeeName, employeeNumber, position, department ;
double otpay, salary, deduction, hrs, rate ;
Scanner input = new Scanner (System.in);

That's my codes but its wrong according to our prof. it should be in frame form. i don't know how to do it since i did not encountered framing since i was started in java.
I have a form containing several fields, 2 of which persist to different table in a database than the rest of the fields on the form. I have no problem persisting the data into both tables of the database, and after the form is submitted I reset the form to its default values. That all works fine.
But in the same session, when I open another form (a search form) and enter search criteria, which then displays a datatable containing the search results, those 2 values that are persisted to another table are not showing up, but the rest of the data is.
Here is the method that calls the persist methods:
@ManagedBean(name = "foreignPartyController")
@SessionScoped
public class ForeignPartyController implements Serializable {
...
public void saveData() {
[Code].....
The values do show up, but the problem is, when a subsequent form is opened in the same session (e.g. a search form) the field for that value shows the actual value, instead of the field being blank.'
I am not sure why the data from the one database ("parent") is showing up, yet the data from the other database ("child") is not.
Is it something I am doing wrong? I thought by setting the setter in the child controller class back to a new instance of the Entity class (PolicyPayment) that it would reset the form to default values, but at the same time retain (or save) the inputted values in the same session.
I have a button on UI which adds messages and when the user clicks on it the form gets submitted, meanwhile the user is clicking on refresh(F5) multiple times which is causing the same message to be displayed multiple times. To resolve this , I am converting the form from a synchronous submit to Asychronous but it is still not working. Below is the code:
Code before:
<td><input class="buttonred" type="submit" value="Confirm Add" name="submit_message"></td>
<s:form action="upd-message" method="POST" validate="true" onsubmit="validateMsg();return false;" enctype="multipart/form-data">
function validateMsg() {
var frm = document.forms["upd-message"];
frm.actionType.value=message;

I have a view button also to select above radio button. When I select that I need all above values to be set in request.
I want to know is there a limit for length of get url request? if if what is the max length.
View Replies View RelatedI have a jsp with an img tag whose src is set to request a servlet to display a chart. This is called from another jsp form where user can select various filters. The first time the request is made all works great. but if the user changes the filter settings and and makes the servlet request a second time the chart stays the same. I have verified the new filter values are being set but the servlet is only being called on the initial request.at the head or called servlet I have(I also call a jquery empty on the div that holds the chart between requests. at the moment it just displays the former chart). It is like it is using cache:
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.setHeader( "Pragma", "no-cache" );
response.setHeader( "Cache-Control", "no-cache" );
response.setDateHeader( "Expires", 0 );
I'm always receiving update requests from numerous vendors. How can I confirm that an update request from Java is authentic?

I would like to know how i can find the process ID associated to a request.
When I run my code that's appear :

But I don't have ExiBeMensagem.jsp in web pages....
When we forward the request to a jsp , I noticed that the url bar address does not change .
I made a form form.html , and set action to a servlet then in servlet class I set an attribute and forward the request to jsp ,which prints the value of that attribute.But the url in address does not actually points to that jsp to which i forwarded the request.
I have to forward my request to another webApplication using post request parameters. In this case Webaplication-1 need send request using post request params to Webapplication-2 & once Webaaplication-2 receives request it has to process & display output.
For this have tried below 2 options which Servlet API provides.
1. RequestDispatcher : this will used to forward request to another resource within the application.
2. sendRedirect() : this method support doGet() of Servlet.
3. Using HttpClient, which is provided by Apache able to do but it will not displaying Output,It sending back response to Webapplication-1 .
Is there any option which will handover request from one webapplication to another webapplication.
I want to create a new instance of a Java model class for each new request coming to a servlet.
How to do that without doing that in doGet() or doPost().
We have a big application which is implemented in basic servlet. WE have Get and Post request in servlet. I want to provide them security if any malicious attack will happen on the form submit method. I want to make it secure. In detail, suppose if any user want to submit form/ any ajax request from my application and if he/she changes the method of submission from POST to GET then how I will recognize this?
I know that HTTPServletRequest object have GetMethod() but how I will detect that it is not changed by Tamper data/Fidler/Watir. One more way, I googled is by using GetQueryString() method but lot of the places I have query paramater in my POST request.
I have to send a request with post parameters from one web application to another web application,both are running different servers.
In my application i don't have any JSP,html only controller part which will handle request extract request parameters & based on request params i'll do a web service call.
My current requirement is based on request parameters i'll send request to another web application with received parameters.
I tried with sendRedirect() ,but it support only get() method.
how to proceed further.
I am building an application that has two types of users. While some of the fields (ie: username, email address, password) are the same for both user types, other fields are different for each user type.
Therefore, I would like to split up the process of registering (ie: writing the user info to database) into two parts:
1) registering the common fields among both user types (servlet 1)
2) registering the specific fields based on the user type that is registering (servlet 2a and servlet 2b).
Therefore, once servlet 1 is processed, I wish to forward the request to servlet 2a or 2b depending on what type of user is registering.
I wish to do this since I will have other parts of my application that will make use of servlets 2a and 2b as well. Is this possible to do (redirect request parameters from jsp to servlet and then to another servlet)?
I want to run a function on load only when a particular parameter is not present?
My question is how to detect in JSP that if a particular parameter is present or not?
