Time-to-market features
The ability to achieve rapid application development offered by both Sun J2ee and Microsoft .Net provide mechanisms that eliminate such constraints for software developers as any dependencies. Though the ability to achieve rapid application development offered by both J2ee and .Net is not equal.

Single-Vendor Solution
This aspect is very strong from the following points of view: legacy integration perspectives and stability of two-vendor bridged solution. Though .Net is a single-vendor solution and J2ee is not one there is a set of techniques to extract all the good of both technologies for your project. So J2ee technologies allow building up powerful single vendor solutions, for example, Oracle, IBM WebSphere, Weblogic and others.

Platform maturity
One of the main requirements for solution implementation is risk mitigation. In this respect more mature platform is more preferable. Both MS.Net and J2ee are marketed for a long time, also both platforms are being supplemented with new features. These facts make the risks for both platforms comparable.

Platform Migration
Technology and business are changing at ever-increasing rates. So your current environment is far from being homogeneous and is a result of earlier technology advances. So to mitigate the negative effects of further platform migration Itransition’s specialists take into consideration these risks and recommend developing of service-oriented application.

Portability
A key difference between J2ee and .Net is that J2ee is platform-agnostic, running on a variety of hardware and operating systems, such as Win32, UNIX, and Mainframe systems.

Scalability
The significant difference between J2ee and .Net scalability is that since .Net supports Win32 only, a greater number of machines are needed than a comparable J2ee deployment due to processor limitations. There are some hardware platforms that require only java-based applications. Itransition’s specialists can make your solution as scalable as possible using tools of either MS.Net or J2ee Platform.

Tools
The toolset provided by J2ee multivendor community as a whole provides advanced functionality. From the other side Microsoft's single-vendor integration features, its ease-of-use are serious advantages when building web services using the set of .Net tools.
