What is JLCA?

The Java Language Conversion Assistant is a tool that automatically converts existing Java code into Microsoft Visual C#, for developers who want to move existing applications to the .NET Framework.

It provides a quick, low-cost method of converting Java applications to Visual C# and the .NET Framework. These applications can then be extended to utilize XML Web services and the complete .NET developer platform, including ASP.NET, ADO.NET, and Microsoft Windows Forms.

What Others Are Saying

"With consolidation and cost cutting the order of the day for many developers and managers, finding a way to more quickly, easily and cheaply move applications from one platform to another has become a top priority. In an effort to ease that process -- and get corporate developers to shift allegiance from Java to .NET -- Microsoft has brought out Version 2.0 of its Java Language Conversion Assistant (JLCA), a tool that converts Java code to Visual C#.

"What we wanted to do was create a tool for those people who already have existing assets, created in either Java or J2EE, to be able to carry forward that investment to the [.NET] platform," said Dan Fernandez, product manager for Visual C# .NET. "It's literally within Visual Studio .NET. You say 'file, convert project,' you point it to where your Java files are and it will literally migrate your application, changing Java source code into C# source code....""

"...The big advance in Version 3.0 is support for converting J2EE 1.3 applications, including JSPs and EJBs. Other Java technologies that can be translated include Java Authentication and Authorization Service (JAAS), Java Cryptography Extension (JCE), Java Message Service (JMS), Java Naming and Directory Interface (JNDI) and Remote Method Interface (RMI)..."

""Let's be honest, you can't spend a weekend rewriting your applications from scratch and expect to get them running on .NET," [Brian Keller, product manager for Microsoft's Visual Studio .NET] said. "The JLCA helps to minimize the hurdles to that conversion process. It gets you about 85% to 90% of the way, so that it becomes realistic to take an application and get it moving to the .NET Framework in that kind of time...""
