But would it not be much easier for the administrator to have an interactive installer who assists him with the installation process. With IzPack it is possible to create a platform independent installer.

In order to write your XML installation files, you just need a plain text editor. Of course it's always easier to work with color coded text, so you might rather want to work with a text editor having such a feature.
Here is a list of free editors that work well :. If you are a developer and tend to write your own patches, extension or features to IzPack sources, or, if you wish to debug your compilation, installation and uninstallation, we recommend these IDE:. All project members can ask the Licence Key to one of the project manager. The other ones are well know open source projects Just like us Though you might not know much about XML, you have certainly heard about it.
If you've ever worked with HTML the transition will be fast. However there are a few little things to know. Each tag can contain text and other markups.
Here is a sample of a valid XML structure :. The only thing you should modify is the encoding put here the one your text editor saves your files to. This brief! During the installation process IzPack can substitute variables in various places with real values.
Obvious targets for variable substitution are resource files and launch scripts, however you will notice many more places where it is more powerful to use variables rather then hard coded values. Wherever variables can be used it will be explained in the documentation. How to do this is explained in detail later in this chapter. The curly braces are mandatory. The value of dynamic variables will be evaluated every time a panel is switched, i. Dynamic variables can have a condition which will be evaluated first.
If it's true, the value would be assigned, otherwise nothing happens to the variable. Parse types apply only when replacing variables in text files. At places where it might be necessary to specify a parse type, the documentation will mention this. Depending on the parse type, IzPack will handle special cases -such as escaping control characters- correctly.
The following parse types are available:. It takes one required attribute : version. The attribute defines the version of the XML file layout and is used by the compiler to identify if it is compatible with the XML file.
This should be set to 1. This element is used to specify some general information for the installer. It contains the following elements :. This element allows to specify packaging options. If not specified, the default will be to create an all in one installer. This element will usually be used to create an installer which spans over multiple volumes, e.
The packaging-element contains the following elements:. The packager tag has the class attribute, which specifys the class to use for packaging. Currently two implementations are available com.
Packager, com. For the MultiVolumePackager, it can have the following attributes:. UnPacker, com. Here's an example how to specify an installer which will create multiple volumes. In this example the volumes shall be CDs with megabytes.
There will be an additional free space of megabytes on the first volume. This will result in the creation of an installer. The installer. This element allows you to define variables for the variables substitution system. The variable substitutor will then replace it with the correct value. Here's a precise sample on how to use desktopshortcutcheckboxenabled and InstallerFrame. This element allows you to define dynamic variables for the variables substitution system. Normally you would use the condition attribute to specify, when a certain value will be set.
This element allows you to define conditions which can be used to dynamically change the installer, e. When you define a condition it will get a type and an id. The id has to be unique. Conditions can be referenced based on this id e. There are several built-in types of conditions. At the time of writing this, Izpack has the following built-in types:. A condition can take the following attributes:. Custom condition types should be referenced by the full qualified class name, e. This will be used to refer to this conditions in other elements.
The condition element can have several child elements depending on the type of this conditions. This is an example which defines four conditions, two VariableConditions, a JavaCondition and a AndCondition which will refer to two of the first conditions. Note, from IzPack 3. The language has the following operators:.
Neverthless if you define really complex conditions it's much easier to define them using the xml structure. This element allows you to set the behavior of your installer GUI. This information will not have any effect on the command-line installers that will be available in future versions of IzPack. The arguments to specify are :. Starting from IzPack 3.
For instance you can use the native look and feels on Win32 and OS X but use a third-party one on Unix-like platforms. To do that, you have to add some children to the guiprefs tag:.
If you don't specify a look and feel for a particular operating system, then the default native one will be used: Windows on Windows, Aqua on Mac OS X and Metal on the Unix-like variants. The JGoodies Looks look and feel can be specified by using the variant parameters. The values can be one of:.
The Substance look and feel toned-down themes can be specified using the variant parameter, with the value being one of: business, business- blue, business-black, creme, sahara, moderate, officesilver. We have reduced the choice to the toned-down themes since they are the only ones to actually look decent the other families colors are way too saturated. This element is used to specify the language packs langpacks that you want to use for your installer. Several panels, such as the license panel and the shortcut panel, require additional data to perform their task.
This data is supplied in the form of resources. This section describes how to specify them. Take a look at each panel description to see if it might need any resources. Currently, no checks are made to ensure resources needed by any panel have been included. Here are the attributes to specify :. Here you tell the compiler which panels you want to use. They will appear in the installer in the order in which they are listed in your XML installation file. Take a look at the different panels in order to find the ones you need.
This is a crucial section as it is used to specify the files that need to be installed. This enables a model in which a single developer is responsible for maintaining the packs and resources related to the development-package assigned to him. In order to provide internationalization for the PacksPanel, so that your users can be presented with a different name and description for each language you support, you have to create a file named packsLang. Please be aware that case is significant.
For the name of the panel you just use the pack id as the txt id. For the description you use the pack id suffixed with. This description is displayed if the user highlights the pack during installation. This can be used to make this pack selectable only to be installed only if some other is selected to be installed.
Circular depedencies are not supported and the compiler reports an error if one occurs. It is possible to restrict a panel to a certain list of operating systems.
This tag takes the following attributes:. This feature can update an already installed package, therefore removing superfluous files after installation. Here's how this feature author Tino Schwarze described it on the IzPack development mailing-list:. It supports a subset of ant fileset syntax, e.
It takes the following attributes:.
