I need to port a ASP.NET MVC app to Java. To make migration easier, I would like to use the most similar Java web framework to ASP.NET MVC.
I know basic Java web development [JSP/Servlets] but I don't any Java MVC framework. What Java web framework would make my migration the easiest?
I have seen a particular pattern a few times over the last few years. In the UI, each new record (e.g., new customers details) is stored on the form without saving to database. This clearly has been done so not clutter the database or cause unnecessary database hits.
While in the UI state, these objects are identified using a Guid. When these are a saved to the database, their associated Guids are not stored. Instead, they are assigned a database Int as their primary key.
The form can cope with a mixure of retrieved items from the database (using Int) as well as those that have not yet been committed (using Guid).
When inspecting the form (using Firebug) to see which key was used, we found a two part delimited combined key had been used. The first part is a guid (an empty guid if drawn from the database) and the second part is the integer (zero is stored if it is not drawn from the database). As one part of the combined key will always uniquely identify a record, it works rather well.
I'm looking for a way to access a Java API from both a Java console application and an ASP.Net application.In short my Java API exposes a series of methods for dealing with invoices. All of these methods are essentially commands e.g.
GenerateAllInvocies
GenerateInvoiceNumber
PrintAllInvoices
PrintInvoiceNumber
All methods will interact with the database. I had believed Web Services was going to be my means for interop. But I have since been made aware of Java Stored Procedures in Oracle.
I got asked to write a java application for my company. I'm a seasoned .Net developer so this is all new ground to me.My task is to produce an invoicing application that has several high level tasks such as:Build single invoiceBuild all invoicesMy company want to be able to call these tasks from a java console application - passing in relevant commands and parameters to invoke the tasks. They also want to be able to invoke the same code from an ASP.NET application.
View 2 RepliesI host a website that has recently been upgraded from .NET Framework 2.0 to .NET Framework 4.0. Within the website, I have an instance of BlogEngine which still requires .NET Framework 2.0. Each website is in it's own application pool. My issue is that when I browse to the blog portion of my website, I receive a 500.19 error with the following information...
The configuration section 'system.web.extensions' cannot be read because it is missing a section declaration The web.conf file that is listed in the error message is the config file that belongs to my root website which is running .NET Framework 4.0. How do I get the two websites to run together in the same website using different versions of the .NET Framework?
I have this cenario:One server (machine) that have framework 3.5. And one site (website) developed for framework 3.5.This site can not be modified (rebuild in other FW version, or others changes).

As I know, the new webaplication work in the server, if I install framework 4.0 in the server.
My question is: Can I install the framework 4.0 on the machine that already have framework 3.5. And continue have sites working with other frameworks version?Or, should I develop my new webapplication in framawork 3.5 ?If I can install the framework 4.0, do I need make some specify configuration during the installation?

View 2 RepliesI recently I have upgraded my web application from 1.1 to 3.5.
Now the problem is support DLLs used in this application still in 1.1 only.
There is no way to change it. While accessing from 3.5 it is not showing any error msg.
But not giving expected results.
Is there any way to run this particular assembly in 1.1 and other in 3.5 ?
I have an old Web application which is using net framework 2.0(build with vs2005), now i need to move the old Web application to production server which has .net framwork 3.5 installed. Do I need recompile the web application with vs2008 or i can just go head move the the Web application without recompiling, it will automatically work?
View 4 RepliesI am programmer analyst working mainly in Asp.net for more than 3 yrs. I always wondered why employers are ready to pay more dollars for the same skill a person have in dotnet. I also see more BPM technologies are based on Java. Like Pega, Tibco etc. I have learned java in my college 4-5 years back.

View 2 RepliesI want to test this code found here. It allows me to auto-load content from server as the user scrolls down the scroll down. I am having difficulties trying to convert code to C#/ASP.NET. Primarily, I want this code to be translated to C#/ASP.NET:
package com.vraa.demo;
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;
public class InfinitContentServlet extends HttpServlet {
private static Integer counter = 1;
protected void processRequest(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
PrintWriter out = response.getWriter();
try {
String resp = "";
for (int i = 1; i <= 10; i++) {
resp += "<p><span>"
+ counter++
+ "</span> This is the dynamic content served freshly from server</p>";
}
out.write(resp);
} finally {
out.close();
}
}
@Override
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
processRequest(request, response);
}
@Override

In addition, I would like to know if I have to make any changes to this JavaScript code:
<script type="text/javascript">
$(document).ready(function(){
$contentLoadTriggered = false;
$("#content-box").scroll(function(){
if($("#content-box").scrollTop() >= ($("#content-wrapper").height() - $("#content-box").height()) && $contentLoadTriggered == false)

$contentLoadTriggered = true;
$.get("infinitContentServlet", function(data){
$("#content-wrapper").append(data);
$contentLoadTriggered = false;
});
}
});
});
</script>
We currently have a simple portal kind of functionality built based on ASP.NET Forms-based authentication. All the existing apps that make use of this authentication mechanism are ASP.NET based (and run on the same domain). So, all works fine. We have a new requirement to get some new Java-based web applications make use of the same authentication as well. All our apps are accessible over HTTPS.
View 1 RepliesRecently we got a project which can be developed either in J2EE or Asp.Net (no restriction from client). Client is asking to give best solution to maintain the project in long run.
Here I don't want to discuss about "Java vs .NET" but need to know which one is preferable to reduce maintenance cost. If I choose any of these technologies, which one will require less development and maintenance cost. Also consider recruiting people like developers, server administrators and software purchase and etc.
If I go to Java, I can choose any Operation System, Web Server, Application Server and database. But for a kind of enterprise applications will there be any low cost when compared to MS technologies?
Simply putting, assume I need to have 100 web servers, 30 database servers. Which one will require less investment?
i have a discussion going on in the organisation where i am employed as a consultant. The discussion revolves around the replacement of a application built using VB6(MDI) thick client. This application has around 100 screen + 40 reports. Used by approx 400 users the reports and the data are pulled using inline queries while the db structure is pretty normalized . the rest of the code is pretty bad. While discussing replenishment strategies we are throwing around a few ideas.
J2EE Web application running on Web sphere using Crystal reports for Reports. ASP.NET web forms web application using crystal reports for reports. Windows Client application (WPF/Win-forms) with reporting services for the reports.
While i don't want to start a flame war(Dot net vs Java or WEb vs Desktop) it would be nice to know the community thoughts on the matter. Just to be upfront i feel that option 3 maybe the best version. ut i would like to know the opinions of others.
I have a jar file exporting some functions which i want to use in my asp.net application. How can i achieve this? Will anything change if i use it in an windows azure application?

I have two fields in a form that a user can only put either 0 and 1. Both cannot have same value. if first amount is 0, the second amount must be 1. and someone show me how to write a validation in Javascript that I can call it from JS.file At the same time, I want to be able to create the same validation when the form is generated dynamically. so the Javascrip validation has to be created from code behind once the input form is created. If you have any link in the site that can show me lots of this kind of example, I want to learn this stuff.

Is it possible to launch a VB sub from Java Script? I have tried a couple of options inclusive of:
Code:
[code]....
The above generates an error: "Microsoft JScript runtime error: Object doesn't support this property or method". On the VB side I have a protected sub named ViewDetail which validates the selected record and the displays all detail related to the record in a new page/window.
Code:
[code]....
The above generates no error, but doesn't redirect to the new page/window either. The Page_Load event performs the record validation and subsequently loads the record's detail.
I am using an obout Grid's double click event (a java script at initiated at the client side) to record the value of the selected row and now want to open a page (performed at the server side) reflecting the detail of the relevant record.
I am getting patient detail and stored that details in the form of XML (.xml) file.
As soon as XML file is created then I need to transfer that file to Java application automatically. (From one server it need to Transfer to another)
Note : I am using ASP.NET (.Net FW 3.5)

I'm considering rewriting a small Http Module i made in ASP.NET in Java. Based on a specific URL, the Http Module inserts some HTML on an empty HTML layout, do some basic reformatting, and finally returns the rendered HTML. Being new to Java web development, what is the equivalent to ASP.NET Http Modules?
