Suppressing DOS window when calling Ant from Java

[Sharad Jain]

I am trying to embed Ant into my application.
The following code gives me what I need.
executeAnt(String antfile, String target, PrintStream myOut, PrintStream 
myErr, int logLevel)
{
       ProjectHelper helper = ProjectHelper.getProjectHelper();
       Project project = new Project();
       project.init();

       logger.setMessageOutputLevel(logLevel);
       logger.setOutputPrintStream(myOut);
       logger.setErrorPrintStream(myErr);
       DefaultLogger logger = new DefaultLogger();
//        CommonsLoggingListener logger = new CommonsLoggingListener();
       project.addBuildListener(logger);
       
       helper.parse(project, new File(antfile));
       project.executeTarget(target);
}

I am able to get it working with proper logging etc.
However, I have one annoyance that I cant get rid of.
When I run this code on Windows machine, a command-windows flashes
when project.executeTarget() gets called. I believe, this is because of 
some kind
of System.out / System.err binding that happens inside createLogger() of 
Main.java ...

I know most IDE(s) (Eclipse/JBuilder) have AntRunner which are modified 
version of
Ant-Main.java and they are able to suppress DOS-window.
I dont know how ?
Any directions will be appreciated.
Thanks,
