Loading a class from a jar

[aditya]

Hey 

The problem is something like this:

I have a the name of the class which contains a function I want to run. When my app executes, I give it the name, and it searches through all jars in /extern-libs and tries to find the class. If this class is found, it creates an instance of this and runs the function.

Any ideas on how this can be accomplished?

Here are a couple ways:

The old school way: http://docs.oracle.com/javase/1.4.2/docs/guide/jar/jar.html#Service Provider

I've also used Brian Clapper's ClassUtil: http://software.clapper.org/classutil/

Thanks. Are there any libraries which use 2.10 reflection ?

I don't know if it is possible to scan jars using the scala 2.10 reflection.

To reflect the found classes you can use smirror.
