[izpack-users] Setting Built-In Variable

[Bartz, Klaus]

Hi Thao,
I thought a little bit about your problem, but the only resolution
I have seen is to create a custom panel.
Following my custom panel to ask for the BEA path.
In my properties file I do not use $FILE_SEPARATOR because it is
something like readonly, else I use a custom variable named
EJBProperties.ServerHomeDir. In method isValidated you can see
how to make the separators we need. There are two variables,
one with UNIX, one with DOS separator.
For creating a custom panel see the docu you have installed (I hope).
There are also some threads in the izpack-users list, e.g. 
https://lists.berlios.de/pipermail/izpack-users/2006-October/002697.html
https://lists.berlios.de/pipermail/izpack-users/2006-October/002729.html
Some threads are broken on the mail archive, therefore search with
"subject" sorting.

Cheers

Klaus
