Hi,
I am trying to use an action that returns directly instances of the
Result class, due to the nature of my application where the result is
dynamically decided by some logic.
My action class method is:
public Result doLogin() throws Exception
{
// etc...
if ( !validUser )
{
addActionError("Authentication failed. Invalid
username/password provided.");
return new ServletDispatcherResult("/jsp/login.jsp");
}
// valid user
session.put("user", userName);
ServletActionRedirectResult result =
(ServletActionRedirectResult) session.get("_prev_uri_");
if ( result == null )
{
result = new ServletActionRedirectResult("/home", "home", "execute");
}
return result;
}
My struts.xml:
<action name="doLogin" class="actions.LoginAction" method="doLogin">
</action>
After executing the action's method I always get a
NullPointerException from ServletActionRedirectResult :S
exception
javax.servlet.ServletException: java.lang.NullPointerException
org.apache.struts2.dispatcher.Dispatcher.serviceAction(Dispatcher.java:515)

Am I missing something?
