How it works

From .NET to Java in three steps

Existing .NET code, callable as native Java — no rewrites.

1

Generate proxies

Use JNBridgePro to generate Java proxies from .NET.

MyAssembly.dll
Proxies.jar
2

Drop into your project

Add the proxy JAR to your project and configure the bridge.

my-app/
├── src/
└── lib/
   └── Proxies.jar ✓
3

Call .NET like Java

Use .NET classes from Java with native syntax — no glue code.

// Java
DotNetClass obj =
  new DotNetClass();
obj.compute();
