CDI+OSGI: bundle packages scope
by Александр Свиридов
I use javase and solution osgi (felix)+cdi(weld)+paxcdi. I have two bundles A and B. Bundle B is a lib bundle.
In bundle A I have one class and one package.
package com.example.firstpackage;import com.example.secondpackage.Class2;publicclassClass1{@InjectprivateClass2 class2;}
In bundle B I have two classes and two packages
package com.example.secondpackage;import com.example.thirdpackage.Class3;publicclassClass2{@InjectprivateClass3 class3;}
and
package com.example.thirdpackage;publicclassClass3{....}
I install and start both bundles.
The problem - pax (or weld) for injecting in classes of bundle A scans only those packages which are imported for classes IN bundle A. In my example - CDI for injecting in Class1 Class2 will scan com.example.secondpackage of bundle B. However, it will throw exception as Class2 needs Class3 but com.example.thirdpackage is not scanned for bundle A (as it's not imported!!!). com.example.thirdpackage is only scanned for bundle B but, as I understand every bundles for cdi has its own scope. How to fix it?
