It may be easier to use the classes of this app directly instead of
using the entire app as "black box".

If not, you may use this code to embedd a java console app:

// redirect standard output
java.io.ByteArrayOutputStream captureOut =
  new java.io.ByteArrayOutputStream();

// flush system out and bind to capture buffer
PrintStream oOut = System.out;
PrintStream nOut = new PrintStream(captureOut);
oOut.flush();
System.setOut(nOut);

// call java app's main method
my.little.java.command.line.app.Main(/* arguments as String[] */)

// close capture buffer, reassign original system out
nOut.close();
System.setOut(oOut);

// write captured bytes (optional)
oOut.write(captureOut.toByteArray());

// captureOut.toString() == output of main

You may catch to much output, if other threads write to System.out
as well. Normally a web app should not do this, but use a logging
facility instead.
