As the title says, I'm trying to retrieve the full interface name from a java class file, example:

import test.IUserService;

public class UserService implements IUserservice{}

I created a listener that gave me acess to the compilationunit of UserService, but now I want to retrive the full qualified name of the interface that UserService is implementing, which is, in this case "test.IUserService"
Can anyone tell me how?

Try
org.eclipse.jdt.core.ICompilationUnit.getTypes()
and then
org.eclipse.jdt.core.IType.getSuperInterfaceNames()

Thanks for the answer!
I've already tried this, but the name returned is the unresolved one, in this example i would have "QIUserService", but i need the resolved one: "test.IUserService".
Is there any way to convert?

Did you try org.eclipse.jdt.core.IType.resolveType(String) ?
