Servlets :: Quiz - Match Request URL To Correct URL Pattern In Deployment Descriptor

May 28, 2014

How to map a request URL to a url pattern in deployment descriptor. I got all the answers right, but I am not sure if the thought process is correct.

<servlet>
<servlet-name>One</servlet-name>
<servlet-class>foo.DeployTestOne</servlet-class>
</servlet>
<servlet-mapping>

[Code] .....

1) [URL] ....
Container choice: DeployTestOne (matched the *.do extension pattern)

Exact match check: Is there a URL pattern in DD which is exactly = /MapTest/blue.do ? NO.
Directory match check: Is there any URL pattern in DD for directory /MapTest ? NO.
Extension match: Is there a pattern in DD for files with extension .do ? Yes !
Select DeployTestOne !

Question - When doing an Exact match check, does the container look for blue.do in DD or does it look for /MapTest/blue.do ?

2) [URL] ....
Container choice: DeployTestThree (matched the /fooStuff/* directory pattern)

Exact match check: Is there a URL pattern in DD which is exactly = /MapTest/fooStuff/bar/blue.do ? NO.
Directory match check: Is there any URL pattern in DD for directory /MapTest/fooStuff/bar ? Yes !
Go for the url pattern for longest pat, that is, /fooStuff/*

Question - When doing the directory match check, does the Container look for /MapTest/fooStuff/bar/ or just /fooStuff/bar ?

EJB / EE :: Temporary Queue - Request Reply JMS Pattern

Oct 24, 2014

I wish to use the Request-Reply JMS pattern. The only part over here I am unsure of is the Temporary Queue and how to reuse it.

This is because the thread that creates the request must be able to map to a distinct reply and return back a response.

I am not sure how the reuse of a temporary queue fits this picture.

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?

Servlets :: Which Is Correct Paradigm In Integrating Two Application

Feb 6, 2014

I am working on an application, which paradigm is correct for implementing:

Client Side: Web Application (HTML/JSP/Servlets)
Intergration: Mule ESB

Client will call Mule ESB flow using HTTP URL and get response from the same..I have two way outs

1) We call Mule ESB from HTML directly and Mule ESB send response back to another JSP page. Then, I need to mention page name inside, Mule ESB flows.

2) Or We call Mule ESB from controller(servlets) and Mule ESB send response back to servlets and then servlets redirect to correct page with manipulated data.

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 :: 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.
