Cast the originally Object(exist in B) as follow but I get a class cast exception:

Thanks for your help


RE: Class cast exception

You have to choose wether to use the package name or not, but is has to be consistent


com.projectA.MyDupplicateA myAObject = (com.projectA.MyDupplicateA) com.projectB.getBObjects()[0];



import com.projectA.MyDupplicateA;

MyDupplicateA myAObject = (MyDupplicateA) com.projectB.getBObjects()[0];
