Re: Plugins classpath?

Hi Nathan,

 different versions of Aquire.jar and XMLVC.jar


As you've discovered CC doesn't have the ability to specify the classpath
per plugin.

 is it possible to set the classpath dynamically in code


Yes it is. You'd need to modify the code where plugins are instantiated to
be aware of the classpath attribute but it should be possible.

Of course you might find it easier to just run two instances of CC.
