[izpack-users] Accessing variables at install time

[Bartz, Klaus]

Hi Paul,
more than one way goes to Rom...
I use the AntActionInstallerListener of IzPack for revise our ear file.
It contains place holder in some config files. For it I have written a 
little ant task which unpacks the ear, uses the replace task and packs
it again. The placeholder are in a properties file. 
This file I create in an other custom action on the fly. There is no 
template, else the defaults are written in the source of the custom action.
All IzPack variables for this have a prefix. All variables with such an
prefix will be write into the properties file. Therefore only the
variable have to be declared to add a new one.
If needed, I can give you the source.
I do not use the UserInputPanel else I write my own panels (in the moment
I change the layout behavior for this). I create simple the variables
in the isValidated() method like
idata.setVariable("EJBProperties.EJB_Host", hostName.getText());

Cheers

Klaus
