Hello there! Your action should return a String like "list" or "success" or
just "something" and then in your struts.xml file, you should add a snippet
in your action for that string. Thus, the framework will be able to render
a result. Your action is returning null, and you haven't defined a result
either. In your action instead of
return null;
use
return "success";
And in your struts.xml inside your action add:
<result name="success" type="dispatcher">
<param name="location">/WEB-INF/jsp/admin.jsp</param>
</result>
