Byte Code Based: Stability

The input for j2js is pure Java byte code. Therefore, extensions and progression of the Java programming language (new Java releases, AOP, Obfuscation) are transparent to j2js and its usage.

Aspect Oriented Programming (AOP)

Supports Aspect Oriented Programming through any 3rd party tool, for example AspectJ.

Obfuscation

Through any 3rd party obfuscator, for example yguard.

Java Native Interface (JNI)

Call native JavaScript from Java and vice versa through a programming interface.

Mixed Modes

Any code free of browser interaction can be executed in any Java VM. Runs on all major browser plattforms.

No Plugin

Does not need browser plugin or applet.

Testing

Unit testing is supported through a JUnit implementation. Tests can be run in any mixed mode.

Compiler Cache

Incremental building your project.

Standards based

j2js uses only standard APIs such as the Java Standard API, W3C DOM, HTML, SVG, and JUnit.
