Hi Everyone,
I am having some issue here with @Resource in a Click Page, it seems like
the bean is not searchable nor injectable by Spring context. I suspect that
maybe it is because I am using the AnnotationConfigWebApplicationContext
instead of plain Spring XML context.
The NullPointerException was thrown when the page get instantiated. I have
attached the full exception and below are my codes that related to the
initialization of web application context.
