Upgrading Installation Descriptors (install.xml)

IzPack installation files try to preserve backwards compatibility as much as possible yet version 5.0 introduced some incompatible changes - mostly for consistency:

Native elements 

The <native> elements must now be contained in a <natives> wrapping element under 5.0. See the section on Native Libraries.

Panel action param elements

The optional <param> element in a panel <action> element now uses name and value attributes instead of key and value child elements. The following examples illustrate the change between the two versions.

<panel classname="TargetPanel" id="target.win">
  <os family="windows" />
  <actions>
    <action stage="preactivate" classname="com.opentext.installer.actions.RegistryReaderAction">
      <param>
        <key>ConfigurationFile</key>
        <value>RegistryReaderConfiguration.xml</value>
      </param>
    </action>
  </actions>
</panel>

<panel classname="TargetPanel" id="target.win">
  <os family="windows" />
  <actions>
    <action stage="preactivate" classname="com.opentext.installer.actions.RegistryReaderAction">
      <param name="ConfigurationFile" value="RegistryReaderConfiguration.xml"/>
    </action>
  </actions>
</panel>

See the section on Panel Actions.

Panel configuration param elements

The optional <configuration> section in a <panel> element permits nested <param> elements. Previously, the <param> element was specified using child elements <key> and <value>. This has now been changed to name and value attributes - see Panel action param elements, above, and the Panels section.

LateShortcutInstallListener 

Change To packselection ConditionDue to refactoring and improvement to the internal workings of IzPack, LateShortcutInstallListener is no longer available. Instead, use the new <lateShortcutInstall/> option in shortcutSpec.xml. See Shortcut Specification for details. 

In 4.3.x, the packselection condition erroneously required that a packid element be provided indicating the pack id.

E.g.:

   <condition type="packselection" id="packselection1">
        <packid>myPackId</pack>
   </condition>

The packid actually refers to the localisation identifier of the pack, which is optional, and non-unique. It should refer to the pack name attribute.

To better reflect this, and to force those upgrading to use the correct attribute,the <packid> element has been changed to <name> E.g.

   <condition type="packselection" id="packselection1">
        <name>Core</name>
   </condition>

See IZPACK-799 for more details.

CompilePanel.Spec.xml

The misspelt packdepency element has been renamed to packdependency.

Default installation directories in TargetPanel.dir.*

IZPACK-798 changed TargetPanel.dir.* etc to be variables, rather than resources.

In 4.3.5, the default directory displayed in TargetPanel may be configured in a text file named:

• TargetPanel.dir.<os name>
• TargetPanel.dir

In the <os name> form, the os name has been one of:

• System.getProperty("os.name").replace(' ', '_')
• "windows"
• "mac"
• "unix"

For 4.3.6, IZPACK-798 changed the above to use variables instead of text files, following the same naming convention.
For 5.0,  the Platform class is used to determine the appropriate variable (see IZPACK-829).

For a more details, see Setting Default Installation Directories.

UserInputPanel

The panel.id attribute is necessary to have here, for example:

<panels>
    ...
  <panel classname="UserInputPanel" id="container.installation.selection.panel"/>
  <panel classname="UserInputPanel" id="new.container.path.selection.panel" condition="new.container"/>
  <panel classname="UserInputPanel" id="existing.container.path.selection.panel" condition="existing.container"/>
    ...
</panels>

The userInputSpec.xml must also contain the panel.id attribute and referred panel IDs from the installation descriptors must exist in the user input panel definitions.

Example:

<userInput>
  <panel id="container.installation.selection.panel">
    ...
  </panel>

  <panel id="new.container.path.selection.panel">
    ...
  </panel>

  <panel id="existing.container.path.selection.panel">
    ...
  </panel>
  ...
</userInput>

The panel.order attribute has been removed from the userInputSpec.xml, since it has been ambigous, see IZPACK-885.

The field validator packages have changed, so obsolete validation classes no longer work. This manifests as validation always failing.

Example: com.izforge.izpack.util.NotEmptyValidator should become com.izforge.izpack.panels.userinput.validator.PortValidator.

Overriding Common Panel Translations

The following changes affect the usage of headline translations in all types of panels:

• Custom translations have to in a resource  CustomLangPack.xml_<ISO3> (renamed from  CustomLangpack.xml_<ISO3>)
• There are two possibilities of translation keys which can be used in the following lookup priority:
1. If a panel ID is defined: <panelId>.<subKey>
2. <Fully_qualified_panel_classname>.<subkey>
• The  order attribute of <panel> is no longer read (ignored) and can't therefore used as part of the translation key any longer.

Example 1:

<resources>
  <res id="CustomLangPack.xml_eng" src="i18n/CustomLangPack.xml_eng"/>
</resources>
 
<panels>
  <panel classname="TargetPanel"/>
</panels>

<langpack>
  <str id="com.izforge.izpack.panels.target.TargetPanel.headline" txt="Please select the installation directory"/>
</langpack>

Example 2:

<resources>
  <res id="CustomLangPack.xml_eng" src="i18n/CustomLangPack.xml_eng"/>
</resources>
 
<panels>
  <panel classname="TargetPanel" id="target.panel"/>
</panels>

<langpack>
  <str id="target.panel.headline" txt="Please select the installation directory"/>
</langpack>
