You need to find other ways.
The usual approach to this is a factory-pattern with an embedded
Jython-interpreter. There is the Jython-magazine that a couple of years
ago brought a few examples of these techniques. They roughly work as this:
- create a jython-file contains a jython-class
subclassing/implementing some Java class or interface.
- write a java-class that instantiates a jython interpreter
- make that intepreter execute a small script (one-liner) to create
one instance of that jython-class, and assigns it to a global variable.
- fetch that variable's value from the interpreter-instance, and pass
it to some java-code that works with it.
This is working for nearly *all* use-cases, the exception only being
rare casese where some Java-framework itself uses something like
classForName to instantiate a class (e.g. struts for action-classes)
But even then, you could simply create a java delegation class with the
There really is no need for the Jythonc, which is the reason it is
discontinued I presume.
