Servlets :: Loosing HTML Data Into Request Parameter?

Jan 23, 2014

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 ?

Servlets :: GET HTTP Request Contain A Request Body?

Feb 25, 2014

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?

How To Retrieve Index Of Specific Element In Array

Mar 3, 2015

I'm trying to iterate through an array of integers and find the start position of the part of the array containing the most consecutive 1s.

For example given the array {1,3,1,1,1,1,5,3,2,1,1}, the method should return 2 and given {1,4,5,1,1,1,5,1} the method should return 3.

So far, I've managed to retrieve the element where the consecutive 1s begin. However, I'm unsure how to get the index of this element and this implementation doesn't work if there is more than one set of consecutive 1s.

public class GetIndex {
public static int getPosition(int[] myArray) {
int index = 0;
int tracker = 0;
int mostOnes = 0;
for(int i = 0; i < myArray.length; i++) {

[Code] .....

Servlets :: How To Forward Request To Another Web Application

Jun 14, 2014

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.

Servlets :: Segregation Of POST And GET Request

Apr 8, 2014

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.

Servlets :: Forwarding Request Attributes From JSP

Jun 24, 2014

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)?

Servlets :: Not Seem To Work For First Login Request

Mar 26, 2014

After confirmation to the login details I added new cookie having logging information and then dispatched this request to controller servlet where this cookie is checked if it is present then user is forwarded to a particular page. Otherwise is redirected to the sign in page. Now the problem is when we add cookies then it is added into "response" object and when we get cookies we get them from "request" object. So for the first time redirection to controller servlet "response" object would not have this cookie as it is not available in "request" object. But will be available for later requests.

My question is what is the way to get this cookie in the first request. Or is there any way to send refresh like response to the browser so that this cookie is added??

Servlets :: Not Reading Request Parameters

Jan 29, 2015

We are starting to deploy virtual desktops in our factory.I have a file upload form that works on conventional desktops but fails on the virtual machines. Notice the lifecycle parameter is not being passed to servlet on these virtual machines but does get passed when ran from standard desktop machine.

This is my form code

<form action="/QMSWebApp/AttachmentListController?lifecycle=attachafileuploadfile" enctype="multipart/form-data">
<div class="hide">
<input type="text" name="docindexno" size="20" value="${attachmentObj.fileindex1}">
<input type="text" name="doctype" size="20" value="${attachmentObj.filetype}">
<input type="text" id="fileuploadformsource" name="fileuploadformsource" size="20" value="${attachmentObj.fileUploadFormSource}">
</div>
<input type="file" id="fileName" name="fileName" size="40" onchange="testFileName()">
<input type="submit" value="Upload File">
</form>
<div id="uploadresult"></div>

this is the servlet error:

AttachmentListController: userName: STEVE DYKE File Attachment Source: SI
AttachmentListController: userName: STEVE DYKE e: java.lang.NullPointerException
AttachmentListController: Parameter List: doctype
AttachmentListController: Parameter List: docindexno
AttachmentListController: Parameter List: fileName
AttachmentListController: Parameter List: fileuploadformsource

Servlets :: Submission Parameter Order Maintained?

Nov 27, 2014

Is there anything in the HTML specification about whether submitted GET or POST parameters must retain their order? E.g. In the following is there anything in the spec that says the following data should be returned in the order they appear in the HTML code. And, most importantly, is there anything that says the firstName and surname fields should actually match up with each other, i.e. the order can change but in the same way for each field?

<form>
<table>
<tr><td><input type="text" name="firstName"/></td><td><input type="text" name="surname"/></td></tr>
<tr><td><input type="text" name="firstName"/></td><td><input type="text" name="surname"/></td></tr>
<tr><td><input type="text" name="firstName"/></td><td><input type="text" name="surname"/></td></tr>
<tr><td><input type="text" name="firstName"/></td><td><input type="text" name="surname"/></td></tr>
<tr><td><input type="text" name="firstName"/></td><td><input type="text" name="surname"/></td></tr>
<tr><td><input type="text" name="firstName"/></td><td><input type="text" name="surname"/></td></tr>

Servlets :: Unicode Post Request Parameters

Feb 10, 2014

I developed some servlet to get unicode parameters via post request. It worked perfectly fine since I set the encoding as below:

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
HttpSession session = request.getSession(false);
response.setCharacterEncoding("UTF-8");
response.setContentType("text/html");
request.setCharacterEncoding("UTF-8");
String fileContent = request.getParameter("fileContent");
}

Now that I have set up my dev environment on a new machine with new eclipse, it does not work.

It displays Ï instead of π.

I've already tried adding URIEncoding="UTF-8" to server.xml which did not work since it only affect get not post. I figured out how to get the parameter with correct encoding on the new system:

String[] parameters = URLDecoder.decode(request.getQueryString(), "UTF-8").split("&");

But I cannot believe that this is the solution because then what's the point of having request.getParameter. I already know that:

String sss = new String(fileContent.getBytes(),"UTF-8");

would not work.
