Re: IDL compilation with ant -> problem?

[G Ramasubramani <gr...@aztec.soft.net>]

    I suppose instead of calling execon, you will have to write your own
task which shall internally generate the dependancies and check the
time-stamps to decide which idl to compile and which not to.

    Have a look at the Javac.java class. It might help you.
