According to the message the Struts inform you [hey]
not found in your action configuration. In the struts.xml
you defined it without slash. Do the same in the annotation. Don't map index.jsp
that could be handled by the container itself but not by Struts2. The name "success" is used by default, so it's not necessary.
@Action(value="hey", results = { @Result(location="/page.jsp") })
Note that @ResultPath
is not necessary.
