Am trying to understand the best practice if any for a
ValidateLoginInterceptor of sorts. In the code below, if the login is
valid then we make a call to:
return actionInvocation.invoke();
In case the login information was incorrect, what should one do?
return ActionSupport.ERROR // In this case would the <result
name="error">/myerrorpage.ftl</result> associated with my action be
executed?
public class ValidateLoginInterceptor implements Interceptor
{
private static final long serialVersionUID = 1L;
private static String EMAIL_FIELD = "email";
private static String PASSWORD_FIELD = "password";
public void destroy()
{
}
public void init()
{
}
public String intercept(ActionInvocation actionInvocation) throws
Exception
{
String email =
actionInvocation.getStack().findString(EMAIL_FIELD);
String password = actionInvocation.getStack().findString
(PASSWORD_FIELD);
if (isValidLogin(email, password))
{
// login credentials were valid
return actionInvocation.invoke();
}
else
{
// login credentials are not valid
// actionInvocation.setResultCode(ActionSupport.ERROR);
Should I be doing this?
return ActionSupport.ERROR;
}
}
}
