How to get installData instance in my own java class

[Nanoart]

In IzPack 4.x, I used AutomatedInstallData.getInstance() to get installData in my own java classes which were executed by ProcessPanel through "executeclass". This method has gone in IzPack 5.x,  what is the solution? 

Many thanks,

Mike

I am also looking for solution.

Hi,

in IzPack 5 there is no global instance for the InstallData, it is held in a container instead. This container is not visible for the executable classes. So far so true.

In case you need to access variable values read-only, the new approach is adding arguments to the class by the nested <arg> element. These arguments can contain references to unresolved variables, which are resolved at runtime.

In particular, this replacement is done in com.izforge.izpack.panels.process.ProcessPanelWorker.ExecutableClass#run.

The definition should look like this:
<executeclass name="my.nice.ExtraClass">

  <arg>${var-to-be-resolved}</arg>

  ...

</executeclass>

It is not possible to access the complete InstallData from an executable class of the ProcessPanel so far.

Thank u very much for quick response.

      Actually i am setting the some of the variables values in executable class based on pack selection. For example. i am installing one component "Test" which user selected in packs panel. so if user select this pack, I want to set the variable ${project.version} value which i am reading from jar manifest file. As we have read only access of variable in executable class in Izpack 5, which approach i can use to resolve this issue.

Thanks

With IzPack 5, there is no approach with executable classes in ProcessPanel.

Nevertheless, you can implement your own custom InstallerListener, where you get this access this way:

@Override
public void afterPack(Pack pack, int index) {
  final InstallData installData = getInstallData();

  ,,,

}

My answer has been somewhat incomplete, there is of course no predefined method getInstallData(). The complete answer can be found here:

You can use almost any API type as argument types in the constructor, which get automatically assigned with valid instances from picocontainer.

Actually i am using AbstractProgressInstallerListener and which has getInstallData() so i used the same. Should i go with this?

Thanks for clarification.

Of course, you can.

Anyway, with the fully featured constructor you might pull in further instances you want to make usage of (for instance for dynamically enhancing language packs etc.).

Hi,
I wanted to get the installData from what conversations written above, but I'm not sure how to fill in the details.
Can you tell me how to write it after or within the code below?

[izpack-user] the AutomatedInstallData.getInstance() method disappeared (google.com)
import com.izforge.izpack.api.data.InstallData;

public class MyListener extends AbstractInstallerListener {

    private final InstallData installData;

    public MyListener(InstallData installData) {
        this.installlData = installData;      
    }

    public InstallData getInstallData() {
        return installData;
    }
}

And Is this the right way to write it in my own process java code?

Actually I don't know IzPack source code structure well

public class HelloWorld {

        MyListener myListener;

public void run(AbstractUIProcessHandler handler, String[] args) {
    installPath = myListener.getInstallData().getInstallPath();
        }
}
