We stumbled across the need to configure WAR-Files during the installation process with properties which are entered in an UserInputPanel.
To do this we had to call an Ant-Task after the installation which would change the respective files in the WAR file.
I refactored the parse system to achieve this with IzPack alone. Syntax in install.xml is as follows:
<pack name="TEST" required="yes">
<singlefile target="$INSTALL_PATH/test.zip" src="test/test.zip"></singlefile>
Doku patch will follow
Comments are welcome!
