RE: Using torque-gen from a java program

Hi,

Thank you very much. It worked that way (i had tried the ant docs, but they
are a little confuse when trying to use ant from a Java file).

I'll put my result here in the event that someone has the same need that I
had:

import org.apache.tools.ant.Main;

        ...
        String[] commands = new String[]{"-f", "build-torque.xml", "sql"};
        Main m = new Main();
        m.startAnt(commands, null, null);

and ant.jar as well as ant-launcher.jar must be on your classpath.


Hope it's usefull.

Hi,

I believe it should not be a problem to call ant from a java program. As
ant itself is a java program, you just have to put the ant libraries in
your classpath, call the correct main class, and use the values which you
would issue from the command line in the String[]argument of the main
class. Look at ant.bat to see what it does (you might have to set the
system properties "by hand")
Perhaps there is an easier way to do it, it might be worth while to check
the ant docs.
