This has been bothering me since I started working with this webapp last year (I had no experience with web development) I don\'t know if this app is structured incorrectly
This happens as a result of the bad workflow design. To correct it you should read about PRG pattern. You can change
<action name="actLogin" class="actionLogin">
<interceptor-ref name="newStack" />
<result name="success" type="redirectAction">actHomePage</result>
<result name="error">Login.jsp</result>
</action>
<action name="actHomePage" class="actionHomePage">
<interceptor-ref name="newStack" />
<result name="success">HomePage.jsp</result>
</action>
other results are not needed, but you can remain them if you need to forward to a different page with the same action in the URL.
