I have a web app using spring MVC + hibernate on the server side and jquery, ajax, javascript on the client side.
What I wish to do is to convert it into an exe file to make it standalone app.
Is there a software out there that can accomplish it? I don't want to recreate it from the scratch and I only know how to do web apps.
convert or move standalone java thread application into Tomcat server container for accessing its JNDI services? Also is it possible to schedule this thread application in Tomcat server? is it possible to keep this app in tomcat as web application and schedule in window's scheduler.
View Replies View RelatedI am working on a web-application where i have a functionality which generates reports based on the data from DB. for small amount of data its working nice if the data is huge its taking more time. to avoid this problem i developed a standalone batch where i generated the jar file for the sources in web-application and made a call to the appropriate methods.
But my problem is if web-application takes 10 secs to generate the report but in the case of standalone its taking nearly 3-5 mins to generate the same report. i didn't do much of the changes in code just using the same code as web-application
I am using tomcat 6 application server to run the web-application for standalone using batch commands.....
I have a project requirement, where I need a desktop java application to interact with web pages. I am currently working in java, so I decided to go with jsp and other java related web technologies. The project requirement is that, there is desktop java application and I need it to interact with web pages. I have zero idea about jsp, jsf etc. Is it possible to make my desktop app to interact with jsp or should I proceed with servlets. If I need to go with servlets, can the front end be designed as an attractive page?

I want to embed an existing JAVA applet in to my swing application which is a standalone application. The applet is used in some other application which is not developed by me or my company. The application is open source application (So I have the source code). The entire existing application is basically one of the parts of my new application.
View Replies View RelatedThe following programs exist:
1. I have a java application which accepts bio potential data every second or two and stores it in the database. This is a socket server which accepts this data from multiple clients and spawns a new thread for processing it to store in the db.
2. I have a jsp page on tomcat server which reads historic client data from database (stored by application 1) and displays it on the page.
The socket server program in 1.) above is not running inside of tomcat server.The new requirement now is : Display all of the human data coming in live on the jsp page.Now the problem: I will now need to pass the live data from socket server (which is stand alone) to the jsp which is running on a tomcat server.
Possible solutions:
APPROACH 1: Run the socket server in the tomcat instead of stand alone and store the frequently incoming data in a java object so the jsp can access this object every second and display it on a graph.
PROBLEM : The stand alone java application does not need to be included in a tomcat server except for the fact that the jsp needs access to the live data. Also, I have read that this is not the best way.
APPROACH 2: Expose the stand alone java application as a web service and communicate with the jsp using REST architecture.
PROBLEM : The complication of using this method is that it will not have the flexibility offered by websockets or server sent events (SSE) of auto updating the latest data. The jsp will have to keep polling for new data every one second which is also not a very good option.

I have JSP application naming myProject ,which has been deployed in webapp folder in tomcat. I want to provide security for myProject folder. I mean, I want to protect it from copying by someone else. Is there any way to do the same.

View Replies View RelatedI've been trying to create a tool that extracts emails from inbox using Apache HttpClient, however I'm stuck at the logging in part itself.This is the code. (I've written it all in a main class and removed exception handling for brevity). More in code comments.
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.CookieHandler;
import java.net.CookieManager;
import java.util.ArrayList;
import java.util.List;
[code]....
Now the thing is, after execution I am returned the login-page again instead of the inbox, which leads me to believe that login did not take place at all.Also the response to the post method in the browser has two cookies "cdata"; "sessionid" populated with values however I get them as empty. I believe that I am losing my session between the first get request and the subsequent post.
I need to invoke a restful webservice Client(Rest) from my Webapp based on some scheduler . Also I need to persist the data which the webservice returns in response. So basically-
1. Scheduler triggers, I need to build the rest service request (JSON) and invoke it.
2. Capture the response of the webservice and persist the data in DB.
Technical stack used- Spring MVC
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.
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 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?

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 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.
