[izpack-users] verifier after install path selection needed

[Bartz, Klaus]

Hi Jürgen,
use a custom panel like

public class ExistentTargetPanel extends TargetPanel
{

    private static final String[] testFiles = new String[] { "server" + File.separator + "lib"
        + File.separator + "my.jar"};


    /**
     * @param parent
     * @param idata
     */
    public ExistentTargetPanel(InstallerFrame parent, InstallData idata)
    {
        super(parent, idata);
        setMustExist(true);
        setExistFiles(ExistentTargetPanel.testFiles);
    }

}

A more complex "example" is JDKPathPanel.
How to create the jar file look into %IZ_HOME%\src\build.xml at the JDKPathPanel entries.
Modifying the label texts is simple, but relative implicit. Look in and %IZ_HOME%\bin\langpacks\installer\<iso3>.xml (e.g. at JDKPathPanel.intro)
You can add the entries

ExistentTargetPanel.intro
ExistentTargetPanel.info
ExistentTargetPanel.extendedIntro

If declared, the will be used automatically.

Cheers

Klaus
