Migrate from J2EE to .NET

Improve performance with Java to NET migration


Benefits of Mobilize.Net J2EE to .NET migration

Java 2 Enterprise Edition (J2EE) and Microsoft's .NET represent the two leading architectures for developing highly scalable enterprise applications. The .NET Framework has a number of advantages that make it particularly appealing if you want to increase your productivity while reducing operating and development costs.

Increased Performance

The performance of an application written in .NET is generally better than J2EE. For example, a benchmark applied to the Nile ecommerce application server shows that the .NET implementation outperforms the implementation using EJBs on a leading J2EE application server by 345% on an 8 CPU system (Microsoft .NET vs. Sun Microsystems's J2EE, p.14).

Increased Productivity

Increase developer productivity up 50% or higher with J2EE to .NET migration. The code produced by Mobilize.Net is readable, maintainable and fully commented.

Less Source Code

J2EE requires more source code than .NET to obtain the same functionality. Based on the Software Productivity Research data, coding a function point in Java requires about 53 statements while .NET requires only 16. In fact, a .NET implementation of the Nile application was written with only 3,484 lines while the Java version needed 14,273 lines (Implementing Sun® Microsystem's JavaTM Pet Store J2EETM Blueprint Application using Microsoft® .NET)


Scalability refers to the ability to handle more workload, typically from the addition of more users. A study developed by ObjectWatch, Inc. states that the .NET platform has a major advantage in total cost of ownership vs. J2EE: You can expect to spend five to ten times as much to handle the same workload using a J2EE/Unix platform as would be required with the .NET/Windows platform (Java 2 Enterprise Edition (J2EE) vs. the .NET Platform, p.24).

Mobilize.Net Takes J2EE Apps To .NET 

As Microsoft's "preferred provider of worldwide upgrade services for customers," Mobilize.Net offers proven end-to-end consulting services to help you accomplish your Java to .NET conversion goals. By outsourcing the entire task to us, we can help you save time and money while minimizing project risk.

Using our highly extensible and customizable Java to .NET migration tool, the JLCA Companion, a large part of the conversion process can be automated, dramatically shortening migration timeframes by eliminating much of the need to manually rewrite unsupported portions of the application. And our team of migration experts will take care of the final code adjustments, delivering in the end a functionally equivalent, guaranteed, and ready-to-deploy system.

Mobilize.Net offers valuable technology and services that help customers easily modernize their legacy applications for use on today’s modern platforms and devices program at Microsoft.

- Shawn Nandi, Sr Director, Cloud App Development, Data & AI Marketing

We were able to migrate our VB6 code to .NET using the VBUC license we acquired through MSDN. After the migration only a few things needed manual modification. So your software did a great job and saved us a lot of time

- JMarco Botermans, Owner - Fluke

“Mobilize.Net has a strong track record of building products that successfully automate challenging source code migrations, and this [product] will empower our customers to get up and running on Snowflake sooner.”

- Chris Degnan, CRO at Snowflake

Mobilize.Net seemed the only one that sorted out the details, not only the basic issues of a migration engagement. Its product, the Visual Basic Upgrade Companion, included unique, powerful features, many of which turned out to be very valuable for this specific project, like ADO to ADO.NET conversion and error handling transformation

- Rod Coles – President, Bold Technologies, Ltd

We ran a proof of concept comparing the Visual Basic Upgrade Companion (VBUC) with other VB6 migration tools and we definitely preferred the way VBUC handled the conversion.
