how would i redirect in struts

[john mattucci]

If im in page a.jsp and some error throws me to b.jsp what is the easiest way to redirect in struts. I have tried to read some tutorials but im quite strapped for time and I was hoping someone would have a simple example that I could use. I need to remember which page the user came from since it could come from any page to b.jsp not only a.jsp.

Thank you all for your time

you should use global action like this ::

 
<action-mappings>    
 
...
 
<action path="/Page_A_Action"
type="someaction"
name="someForm"
input="/a.jsp" >
<forward name="success" path="/Success.jsp" />
<forward name="failure" path="/Page_b_Action.do" />    
   
</action>
 
<action 
    path="/Page_b_Action"
    type="org.apache.struts.actions.ForwardAction"
parameter="/b.jsp">
</action>
 
...
 
<action-mappings>    

This will help you.

Ok maybe im lost but I dont see how that will send me back to the original page once the action is completed. What I want to check is if the user is in session in any page i.e. jsp. If he is he can proceed otherwise send him to logon.jsp and once logged on send him back to the page that he was on.

What I want to check is if the user is in session in any page i.e. jsp.

you can do like this ::

1. check in Action Class

2. Check in jsp page ::
- use struts -tag lib :: present or notpresent
- create some util class to check that and call it in jsp page.
- create your custom taglib to do that.
