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.

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 ?

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 now know the basics of JSP and Servlets and I am going to make my own web app (shopping cart).I am having great difficulty in making a blue print for my code. But, I don't know if my blue print is useful or even missing something. where I can learn a formal process to make blueprints (not algorithms or flowcharts) for my code/web app ? I want to be able to make such amazing blueprints, that a beginner coder could simply follow the requirements and do all the coding himself.
What I did so far -
1 - Finalize a small list of features in the app.
2 - Identify all the entities or classes needed for the app - Customer, Product, ShoppingCart, etc.
3 - A list of all the web-pages/servlets/jsp's that the app might require.
I wonder if I can start coding right away. I hope that I have not missed something which will bite me later and will require a whole rewrite of the code.

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.

I am trying to design properly a simple 1to50 game (yes, the one that is so popular among mobile apps), but as a web application that allows two player games. I tried to document myself on the technologies I could use and came to the decision that some kind of Java would be suitable. I know that HTML, HTML5, CSS, JavaScript are client side languages with what I can basically design the client application that runs on a web browser. I installed Tomcat web server, configured Java Servlet API, done some research on Servlets and JSP, but I still cannot really imagine how all of this can work. Servlets form the Controller, JSP files the Model? How can I make them communicate, how can Servlets "tell" JSP files what to dynamically generate? Can JSP files communicate with JavaScript? Is JavaScript even necessary?
I thought that this question is not basically about a specific thing regarding JSP or Servlets, more about design and general concept, that is why I put this question under beginning Java.

On Form Submit my url changes from
1.localhost:8080/Workflow/admin/GetReports?fname=Form1
to
2.localhost:8080/Workflow/admin/EditReport
Form action is EditReport(Servlet Name).
Now on EditReport i perform the databse operations and forward the request to the GetReports?fname=Formname Servlet using Request Dispatcher.So that i am on the same page which is the first one (1) i started from.
Now Everything works fine on the .jsp page But the url remains unchanged that is the second one (2).
Now if i hit the URL again i.e. localhost:8080/Workflow/admin/EditReport it will give an error.
So how to rewrite the url i.e. from admin/EditReport to /admin/GetReports?fname=Formname after performing all the operations.?

I am on developing a web application (using struts). So most of my web application use cases are reading and presenting data to the users.
But i need to write the another set of programs to keep on reading the data from another data bases and update my database. I have list of timings at which i should read the data from each of other sites (i.e. i know when the other databases gets updated information). Its almost every 20 mins..
Now i want to design the app.
1. Should i include the data read programs as part of my Web application ( means runs in same server JVM) and make the threads as daemon threads..?
2. Should i write another application (offline application) runs out of server in another JVM ?

I would like to know how we can deploy one Web application on multiple server to share the work between them? My first thought is that we just deploy the same war file on different servers that connect to the same database. However, what will happen when a user enter something like [URL]? How can multiple servers share the same domain name and how the requests from different users are redirected to these different server?

My application has two Application servers, App1 and App2..
We are using weblogic 8.1 Application server
There is session replication done in weblogic.xml file .
<session-descriptor>
<session-param>
<param-name>InvalidationIntervalSecs</param-name>
<param-value>1</param-value>
[Code] ....
The application works fine but currently there is data getting replicated among different users. Is it the problem of session data getting merged with other session data or is it server cache not getting cleared or is there any setting to be changed in weblogic application server??

I want to implement a 'Keep me signed in' option in the login page of an application. I have noticed this option is present in the form of a checkbox on the login page of many websites but i don't know how it can be coded . When selected, a user is no longer asked for his username and password on subsequent sessions but he is automatically given access.

I need to track the client IP address from where user requested to my application.
I tried following:
request.getHeader("HTTP_X_FORWARDED_FOR"));
request.getHeader("X-Forwarded-For"));
request.getHeader("Proxy-Client-IP"));
request.getHeader("WL-Proxy-Client-IP"));
request.getHeader("HTTP_CLIENT_IP"));
request.getHeader("HTTP_X_FORWARDED_FOR"));
request.getRemoteAddr());
String ip = InetAddress.getLocalHost().getHostAddress();
In which InetAddress is giving my local machine IP when i run my application in localhost, but I mapped localhost:8080 with IIS server then InetAddress not giving exact IP address. How can we resolve this?

For one of my project, required to capture the audit history reports of all the activities of the users within the application.
We are using Servlet/JSP in J2EE environment.
For Ex: Whenever user updates some fields, we need to capture the Old value, new value, user id and time stamp. We have single form with more than 200 fields.
Just want to know the best way to do this..any frameworks available for it...or doing at the database side like using triggers..
