Some Major Differences Between J2EE and .NET

Today having web presence has become a necessity for online merchants and businesses alike. The web is filled with several web development platforms. However, J2EE and .NET are two most extensively used platforms that are used by developers for web application development. Both these platforms enable developers to streamline the process of developing web applications by providing them with modular components and services that helps offer a standard way for executing tasks. With help of these components businesses no longer have to focus on programming and can concentrate more on accomplishing the business requisitions.
Undoubtedly, both J2EE development and .NET development are excellent choices – when it comes to building websites and applications. However, there are some differences between the two that might make one surpass the other in a particular situation.
Platform – Single vs. Multiple
A key difference between both the platforms is that while J2EE can run on multiple platforms, DotNet on the other hand, is a property of Microsoft and can only run on Windows platform. Plus, though you can purchase J2EE products from any vendor, DotNet products are made available by Microsoft only.
The Language Factor
J2EE is written only in one language that is Java, also all the J2EE components such as EJB and JSP are written in Java. In contrast, .NET facilitates development in multiple-languages – the main languages it supports are Visual Basic .NET, C# and C++.
The Cost Factor
Both J2EE and .NET uses Win32 platform, a cost-effective alternative to UNIX and other operating systems. However, Microsoft's renders web development solutions at a relatively lower price than J2EE. That’s because, when building an application in J2EE developers have limited choice over language – Java is the only language they can use. Conversely, DotNet provides developers with the flexibility to choose among multiple languages – they choose one that incurs less development cost.
Rapid Application Development (RAD)
J2EE provides developers with state management that reduces the need for programming and renders better RAD. In comparison, .NET at present does not support container concept, and some functions that are available automatically within the J2EE development environment needs to be hand-coded in DotNet.
The Perfect Fit for Developers
J2EE is the best bet for veterans and knowledgeable developers looking forward to have programming control over low-level services that ensures improvement in performance like caching. Whereas .NET does not provide such low-level services, and also does not provide support to introduction of errors that might affect the system, and this language more appropriate for novices.

Embracing web services has become critical for enterprises. Today you are offered with more than one choice when it comes to choosing web development environment. But .NET and J2EE are the two commonly used platforms. Choosing one among the two can be daunting, as which one is better largely depends on your business needs. But, aforementioned are few factors that will help you understand where one fails other – be it in terms of platform, language, cost, RAD or empowering developer. However, the end choice is ultimately yours.
