JNBridge upgrade helps Java and .NET get along better


By Robert Mullins
May 5, 2008 — 
Although Java and .NET are thought of as a twain that will never meet, the simple fact is that there’s a demand for tools that allow Java and .NET to interoperate. One company is throwing away the idea of translating Java into .NET and betting on its bridge-building skills.

JNBridgePro 4.0, expected to be released this Wednesday, introduces plug-ins for the Java-based Eclipse IDE and the Microsoft .NET-based Visual Studio IDE. The JNBridge tool creates proxies for Java code classes to run in a .NET environment and .NET proxies to run via Java.

What’s new is that the proxy tools run directly in Eclipse or Visual Studio, eliminating the need for a developer to leave their preferred IDE to find the proxies, said Wayne Citrin, CTO of JNBridge.

“You can keep working in your development environment and the proxy building environment becomes part of the development environment and the whole build cycle,” Citrin explained.

JNBridge’s interoperability tool enables .NET code to run in Java, and Java to run in .NET, by sending messages across a bridge between the two in a language the company created that both Java and .NET understand, continued Citrin. This is an alternative to other tools that “translate” Java into .NET and vice versa, presenting a risk that something could get lost in translation.

“The act of translation can introduce errors, and there are maintainability problems as Java and .NET evolve,” Citrin argued. With JNBridge’s approach, “The messages are being translated, but the underlying code is not.”

The 4.0 upgrade also includes full 64-bit support and a data compression/decompression feature so that messages can be transmitted more quickly.

Demand for the new interoperability tool came, in part, from ISVs that want to expand the market for Java-based APIs into the .NET framework, Citrin explained. For example, Hungarian firm ChemAxon, which specializes in APIs in the pharmaceutical industry, developed a Java graphical widget to visualize molecules in research.

“They want to sell to a much bigger market than just the Java market … they used our technology to wrap that Java widget into .NET and now they can sell it to .NET users,” Citrin noted.
