[izpack-users] Accessing variables at install time

[Bartz, Klaus]

Hi Paul,
attached my InstallerListener for writing all IzPack variables with the
prefix "EJBProperties." into the file $INSTALL_PATH/project/system/ejbsystem.properties.
One reason to put it not in the contribution of IzPack is, that a common version of
this "peanuts" needs the 5th time or more.
You see, much of the configuration of this custom action is hard coded. May be a 
configuration file driven custom action will be nicer, but for my requirements the relation
between implementation time, benefit and maintenance is very good.
In the method "setFixedEJBProperties" I set defaults and properties which value I can
resolve from already setted IzPack variables.
 
Hope it helps
 
Klaus

Hi Klaus,

Thanks for the feedback. Yes, sample source would be valuable :-)

I'm prepared to do custom code for this, I just wanted to avoid reinventing the wheel. I would think that this would be built in--after all, one has just gathered up all a user's input for an installation but there is no standard mechanism to apply that data. 

I'm impressed by the product and hope to be able to contribute to it as well.

Cheers,
Paul

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
