[izpack-devel] Finding Default InstallationDirectoryforProgramsunder Windows

[miraodb]

Hi Guyz,

First of all sorry if i'm missing something but this discussion was hard to 
follow for as i just came back from business trip...
Just one thing i don't get, are you guyz saying that doing :

<res src="TargetPathLin.txt" id="TargetPanel.dir.unix" />
<res src="TargetPathWin.txt" id="TargetPanel.dir.windows" />

with TargetPathLin.txt and TargetPathWin.txt files being at the root of your 
installation doesn't work ?????

Coz it certainly works for me !
If that's really the case i'm really lost. I think that either something 
went wrong in the latest merges or that i simply don't understand your 
problem.

Lemme know what the deal is.
I do realise something from your previous mails,

$APPLICATIONS_DEFAULT_ROOT/Pulinco/MyProductXY

this is probably what is in your targetpathxxx.txt

problem could be that it's not parsed at all. Coz i have a hardcoded path 
without blanks and it works fine (/apps or c:\apps)

Can you please send me your install.xml and confirm to me that if you use a 
hardcoded path you still have the problem.

Cheers,
Fabrice

Hi Klaus

I think you missunderstood me a little bit. I do not claim about the code " 
that it is badly designed" or something similar.
I program in Java since 1996, so I know the issues that where there in the 
early stages of java (and some of them are still there :-(

To introduce myself:
- I work at Pulinco (www.pulinco.com) near Bern in Switzerland.
- I've studied Computer Sciences in the "Biel School of Engineering" from 
1995 until 2000
- I work on a Product called "TopEase XBench" since 2001
- We used InstallAnywhere until now and are looking for an alternative 
Installer since the Future of InstallAnywhere is very unclear (merger of 
zerog with InstallShield, no support for Windows Vista yet)

Anyway, when you talk about Java1.1.8, I read in the docs, that I should 
compile IzPack with a Target JDK of 1.4 .
But what is the minimum Java Version that izPack is meant to run on? Do I 
have to compile for 1.2 (or even older) class compatibility? This is useful 
information, if I have to send you patches as you know.

What would be interesting is, if someone (maybe I ?) has to cleanup the code 
or the documentation for that "TargetFactory.getDefaultInstallPath" and/or 
"TargetPanel.dir" which ?

Markus

Hi Markus,
in the meantime I agree with you that IzPack should also find the right 
default path
for applications on boxes with WindowsXP.
Last time we have discussed a little bit about the best way.
I am waiting for a WSH script from you until yet...But I agree with you, 
that a simple environment
variable usage will be more robust, if the setting is common. I agree also, 
that it should have
the old behavior as fallback. It should be no problem to check the existent 
of the variable,
check the existent of the given path and so on.
You sad, you will create a patch for InstallerBase. Nice, I will wait now 
for this.
You know patch as diff -u or as patch file.
To the other points of your email I can see only less because the code was 
not written by me.
May be it is quite adventurous or the usage was very uncommon, but I think 
the developer has
thougth something about it. You know, the code is a little bit older.  Do 
you ever worked
with Java 1.1.8 on Windows 95?

As I sad, I am waiting for your patch (that with the environment variable)

Cheers

Klaus

Hi
I already posted this issue on the User mailinglist.

The current official Release (3.9.0) does not read out the ProgramFiles 
Folder from Windows. Instead it is read from a Properties file according to 
the current Language on the system.

On International Installations of Windows with LanguagePack != English, this 
fails always. Outside English-spoken countries, the international Version of 
WindowsXP is the Quasi-Standard for Companywide Installations of Windows.

On such Systems, the Programfiles Folder is "Program Files" per default, no 
matter which languagepack is installed (so you have a german system with 
"C:\Program Files" as the Programs folder.

I made a patch now, which tries to read the Environmentvariable 
"ProgramFiles" in the class "InstallerBase". If it fails or is not defined, 
it falls back to the current implementation, which is sufficient for older 
(pre W2K) systems (even if it is quite adventurous to derive the drive 
letter from the user's home path). I took the Environmentvariable instead of 
the Registry Key because reading out the registry Key requires further 
classes and components.

What is left as a todo is the fact, that there is a Class called 
"TargetFactory" with a Method "getDefaultInstallPath" which is in fact never 
called. The Documentation states, that one can define a default 
installationdirectory using the resource "TargetPanel.dir". Due to the Fact, 
that "TargetFactory.getDefaultInstallPath" is never called, the setting of 
TargetPath.dir has never an effect!

What should be the desired Functionality? Should the Value from 
"TargetPanel.dir" overwrite the System default if defined? Is this feature 
ever used (its very uncommon to do this when packaging the installer)?

Regards
Markus Schlegel
