RE: Does Struts automatically populate an actionForm in sessionscope??
Click, I think the light bulb just went on.So, in general the sequence is something like this??? 1. A user requests a form 2. Struts creates a session actionForm (based on scope setting in action map) 3. ??? Does the first jsp need jsp:usebean scope=session name=x / or does Struts know that the bean is in session scope? Does Struts put the sessionid inside the form? 4. User submits form for first time and Struts populates the actionForm parameters 5. action gets form, if access to form data is needed use request.getSession() and modify as needed. 6. return mapping.findforward(sucess) 7. The next page has to have jsp:usebean scope=session name=x / 8. The user adds/modifies data and submits form. 9. Struts does NOT populate actionForm 10. action has to HttpSession session = request.getSession(); session.getAttibute(attributename) or session.setAttribute(attibutename) 11 repeat 7-10 as needed.

Proper conditions for setting and getting an actionForm in session scope are ? actionForm scope in struts-config is set to session actionForm implements java.io.Serializable empty constructor for actionForm request.getSession() for accessing parameters If the actionForm is in scope, I should see the sessionid appended to the uri in the form? I have added a System.out.println to a couple of setters in the bean to see when it is getting populated, but nothing happens when the form is submitted. Many thanks for your valuable time.

How to get form values when actionForm is in session
I am trying to get the values from my actionForm that is in session scope but get nothing when I use: HttpSession session = request.getSession(true); OperatornetworkForm form = (OperatornetworkForm) session.getAttribute(operatornetworkForm); //operatornetworkForm is the name of the form bean set in //actionmappings. System.out.println(The submit value is + form.getSubmit()); Any suggestions?

Re: How to get form values when actionForm is in session
I don't need a new session so removing true is a good idea. Thanks
I did another test, but fetched another string attribute instead of the
submit button value. Got the correct value from the string so I am
seeing my session data. Though why would I not get something back from
submit attribute? I have getters and setters in my actionForm
getSubmit() { return submit }
setSubmit(String submit) {this.submit = submit}

Hi
Are you sure you have an existing session? Using
request.getSession(true) will create a new session if one doesn't
already exist.
Try this instead. Placing the form that is passed in to your Action
class' execute method, into the HttpSession.
The form bean isn't put into session for you initially, which i think is
what you are expecting.

Re: How to get form values when actionForm is in session
Sorted it out. Need to create a property with the submit, create getters
and setters for that property, and fetch the property instead of the
submit.
Thanks

Re: Filter to redirect to welcome action when pre-compiling JSPs
Hi Jason, At this very moment, I am trying to solve a similar issue. Would you mind posting the relevant snippets from web.xml and struts-config?

My WelcomeFilter takes a Struts Global Forward, looks up the forward (in this case it would return /Homepage.do). I could have just put /Homepage.do as the forwardName and use req.getRequestDispatcher(forwardName).forward(req,res) instead of messing with the Struts code. Hmm, maybe that would be nicer... I might change it now :) struts-config.xml: struts-config ... global-forwards ... forward name=homepage path=/Homepage.do/ ... global-forwards ... action-mappings ... action path=/Homepage type=org.apache.struts.actions.ForwardAction parameter=main.homepage/ ... /action-mappings ... /struts-config Note: The action /Homepage forwards to the parameter main.homepage which maps to a Tiles definition eg in tiles-defs.xml: definition name=main.homepage extends=.mainLayout but I could have used something like WEB-INF/jsp/pages/Homepage.jsp for the parameter Hope this helps...
