[izpack-user] How to specify default value of INSTALL_PATH variable

[Barbara Rosi-Schwartz]

Hello.

 

When I run my installer, which contains the TargetPanel, the installation path field is automatically filled in with a default path which I have not defined. How do I go about changing that default path in the configuration files?

I don't know about IzPack 4, but in IzPack 5, you can't do it via the configuration files.
You can either:
* set the INSTALL_PATH system property. E.g., on the command line:
    java -DINSTALL_PATH=my-install-path  -jar installer.jar

* set the installation path in code, by invoking the setInstallPath(String path) method of AutomatedInstallData.
   You could do this within an InstallerListener, or a PanelAction, for example.

Hi Barbara!

In your install.xml, have this

<variables>
    <variable name=TargetPanel.dir" value="haha" />
</variables>

Read this link if you want to be more specific:
http://izpack.org/documentation/panels.html#targetpanel


If you want to define a variables.xml file instead [so that install.xml only contains packs information, and all variables information are placed in a different file, do so:

    <variables xmlns:xi="http://www.w3.org/2001/XInclude">
        <xi:include href="variables.xml"/>
    </variables>


and in variables.xml:

<?xml version="1.0"?>
    <xfragment>
      <variable name=TargetPanel.dir" value="haha" />
    </xfragment>

Hope this helped!

Cheers,
Dustin

Ah yes - thats probably the same in IzPack 5.0 as well.
However, internally the install path will be populated with the IzPack default value, until it is overridden by TargetPanel.

So I guess the TargetPanel should be one of the first panels then, to avoid the DEFAULT value being put in $INSTALL_PATH for some panels placed before the TargetPanel.

Unfortunately neither one of the two solutions (TargetPanel.dir or env variable) seems to work for me. The TargetPanel keeps on showing izpack’s default value regardless of how early display that panel. I am using IzPack 4.3.4.

 

Any other ideas?

 

Thanks,

B.

We have the following:

<resources>
...
<res id="TargetPanel.dir.windows"
src="install/default-dir-win.txt"/>
<res id="TargetPanel.dir.unix"
src="install/default-dir-unix.txt"/>
...
</resources>

The referenced text files include the default pathnames to use for the
given OS.

This last solution that uses a resource works for me, thank you very much, Earl!!!

And many thanks also to Dustin and Tim for offering alternatives.

That seems very convoluted. A better solution would involve variables e.g.:
<variables>
<variable name="TargetPanel.dir.windows" value="c:/My Install Dir"/>
<variable name="TargetPanel.dir.unix" value="/usr/local/bin"/>
</variable>

I'll JIRA for 5.0.
