I dont not understand very much about Struts2 inject process but I fixed my problem extending the compositeActionMapper with the following one:public class DebugCompositeActionMapper extends CompositeActionMapper { @Override @Inject(StrutsConstants.STRUTS_MAPPER_COMPOSITE) public void setActionMappers(String list) { if (list != null) { String[] arr = list.split(","); for (String name : arr) { if (container==null) continue; // LINE ADDED Object obj = container.getInstance(ActionMapper.class, name); if (obj != null) { actionMappers.add((ActionMapper) obj); } } } } } I worked since it do not throw the Null Pointer Exception and it seem during injection process the function setActionMappers is called twice. One before the container is set and other after.
Do the call stacks during those two calls reveal anything useful about how/why it's getting called twice (once before it sounds like it should)?
If container is null during one of those calls, won't it be null during the entire method call? If so, why not put "if (container == null) return;" as the first line of the method instead of re-checking it for each potential mapper specification?
