Goodmorning all,

I'm going to realize something like a Singleton object in Eclipse 4.
I've got a class (MyLogger) and other classes should share an istance of it.
This idea can be realized through injection? I tried to use @Singleton annotation, but I did not understand how it works.

Very thank you.

Well I'm not sure about the @Singleton contract either, the easiest way
although to inject the same instance into all your POJOs is to put the
MyLogger-Instance in the IEclipseContext of the MApplication.

I've realized my purprose with use of
@Creatable
@Singleton
public class MyClass{...}


Thanks Thomas Smile

Did that really create only one MyClass? Or will it instantiate multiple instances of it?
