It's simple if you know the names and the possible values of the variables that contain user input data. For example we generate the hsqldb-persistence-service.xml with the velocity template http://anonsvn.jboss.org/repos/installer/jems-installer/trunk/templates/j... based on the $database variable. (Even though the file name remains "hsqldb-persist.." the contents are overwritten.) The $database variable (and most other variables) are being created and assigned in the user input panels defined here http://anonsvn.jboss.org/repos/installer/jems-installer/trunk/userInputSp.... Here we define the forms and the controls (each control is mapped to some variable). Once the user fills out the forms in the panels (all variables set), during the file-copy phase the .vm templates are processed.
