----------------------------------
Summary: Using iPOJO in a JavaFX Application
Key: FELIX-4784
URL: https://issues.apache.org/jira/browse/FELIX-4784
Project: Felix
Issue Type: Bug
Components: iPOJO
Affects Versions: ipojo-manipulator-1.12.1, ipojo-runtime-1.12.1
Environment: Ubuntu 14.04, Java 8 - JavaFX 8, Apache Felix
Reporter: Arjay Sitoy
Priority: Blocker
I am doing a Javafx application in {{Apache Felix}} along with some experiments
using {{iPOJO}}. I also posted the same question in
[*StackOverflow*|http://stackoverflow.com/questions/28289948/using-ipojo-in-a-javafx-application].
First is I called the {{Application.launch()}} method in a different class and
then start an another class containing the iPOJO {{@Requires}} like this:
{code}
public class JavafxApp extends Application {
@Override
public void start(Stage primaryStage){
/* Do nothing here because I thought I can initialize JavaFX in a
different class */
}
public void start(){
Platform.runLater(() -> {
launch(JavafxApplication.class);
});
}
}
public class MyApplication {
@Requires
LibraryClass class;
@Validate
public void start(){
JavafxApp.start();
class.someMethod();
}
}
{code}
This implementation throws this exception, {{java.lang.IllegalStateException:
Toolkit not initialized}} but the iPOJO located the implementation class of the
{{LibraryClass}} interface.
After some research I found out that the application should be inside the class
that extends the {{javafx.application.Application}} so I did some restructuring.
{code}
public class JavafxApp extends Application {
@Requires
LibraryClass class;
@Override
public void start(Stage primaryStage){
class.someMethod();
}
@Validate
public void start(){
launch(JavafxApp.class);
}
}
{code}
Now the iPOJO throws a {{RuntimeException}} and the {{LibraryClass}} becomes
null and the application throws a {{NullPointerException}}.
My questions are:
- Is it possible to use iPOJO in this situation?
- If it is what is the right way to use iPOJO in a JavaFX application?
