Re: [Wrapper-user] cant access main function in parent class

[Aiman Y. <wr...@co...>]

Thanks for the quick response, Leif.

I also hadn't known it was possible that it could work without its own main
function until I started getting that error and investigated.

The reason the child is launched from the command line is because the parent
is an abstract class. The child(ren) statically sets a variable (among other
things, but I didn't look into it very deeply) which is used in the Parent's
main class to identify what kind of child it is. So for different children
objects to be instantiated (they are different types of servers), the
children have to be run to identify themselves.

I would have replied sooner but I was trying to get that dummy class written
and compiled. It became somewhat confusing...as confusing as the above
paragraph, and for the same reasons :)
But its working for now.

And any idea about if/when a new version that can call the parent's main
would be available? I'm not looking for anything specific...just a "next
month" or "within 2 years" type of answer.

Thanks again,
Aiman
