Integrate applications using multiple programming languages into a Java application

Is there an open source application that could integrate applications using multiple progra开发者_如何转开发mming languages into a Java application?

Some options:

• Languages that can be compiled and run into the JVM, like python and javascript. But you might have a difficult time if the programs where not built from the beggining to run inside the JVM.

• JNI, java's native interface. This allows interfacing Java with native (i.e. C) languages. If your other language is not C or C++ then probably you will need to write a native interface for them too.

• API. Using web services or socket communication have the two languages communicate.

• Sharing data. Having both programs share files or databases in a common format.

Not quite sure what you mean, but there are several languages that could be compiled to Java byte code and run under JVM.

The Java Native Interface is a programming framework that allows Java code running in a Java Virtual Machine to call and to be called by native applications (programs specific to a hardware and operating system platform) and libraries written in other languages, such as C, C++ and assembly.
