RE: Struts w/Ajax with Struts again
Hi Martin I dont want to fillup the post with clutter. The action elements of the file are normal. What I was able to reproduce was that if I enter the action with an Ajax call, using prototype, and return with mapping.getInputForward(), the session objects do not get updated; even though I update them in the action. If, however I enter the action with a click off a html:submit button the session objects do get updated and I see the current values on the form. I never expected that. Should processing through an action and the updating of the session objects, be the same however the action was called? --- On Tue, 7/21/09, Martin Gainty mgai...@hotmail.com wrote: From: Martin Gainty mgai...@hotmail.com Subject: RE: Struts w/Ajax with Struts again To: Struts Users Mailing List user@struts.apache.org Date: Tuesday, July 21, 2009, 3:08 PM post the complete contents of struts-config.xml event timing is crucial specifically you'll need your Ajax control to detect ON_COMPLETE a fairly comprehensive example of handling ON_COMPLETE at http://struts.apache.org/2.0.14/docs/ajax-validation.html any objections to using new version struts-2.1.6..its stable enough for G/A?

Hi cpanon, what i meant is to do real refresh of the page, just like the one when You hit F5 button or click Refresh on your browser. Try this: 1. load the page 2. do some of that ajax stuff 3. hit F5 is the result like You have expected? After all not using ajax at all may be best solution in your case.

RE: Struts w/Ajax with Struts again
Hi Martin
Thanks, however I havnt migrate to Struts2 yet. What I was hoping for was a
technique to get all the session objects reprocessed upon return from the Ajax
call. I am unclear that if I do the mapping.getInputForward(), does that force
tomcat to reprocess and the jsp reprocess all the session objects? I have also
tried returning from the Ajax call with a forward to the page and that doesnt
force a redisplay of updated values. That should, correct, it is no different
than any other usage and with the json result being stored in the header it
will not matter for that processing.

better off setting it in the action
then access it thru ognl e.g.
#session.setSeeMe
http://struts.apache.org/2.0.14/docs/ognl-basics.html
if you want to see a bean described as
package package;
public class bean {
private String BeanParamName;
public void setBeanParamName(String BeanParamName){
this.BeanParamName =BeanParamName ;
}
public String getBeanParamName(){
return BeanParamName;
}
}
in your jsp use s:bean as here
%@ taglib prefix=s uri=/struts-tags %
html
body
s:bean name=package.bean id=id
s:param name=BeanParamNameBeanParam/s:param
s:property value=%{BeanParamName} /br

Hi Martin
Thank you. So I may be misunderstanding something. If I return to the Ajax
call with mapping.getInputForward() for the defined input attribute of that
action processing the Ajax call, should I see changes in the session objects
displayed? Because before I return I set an element in the
actionForm.setSeeMe(hi), set the session.setAttribute(actionForm,
modified) and I do not see it in the display. I am accessing that element
with the ${seeMe} syntax. I am seeing the json results, but not what I put
in the actionForm. That is what I would organically expect to see. Can
you clarify this? tia.

ajax's responsibility is to return either json or html formatted text to
innerHtml attribute of div tag identified in ajax call
other activity such as refreshing session attributes would need to take place
in the action class..upon return from action all tags of the jsp would
re-display the content based on the refreshed state for those session
attributes
another strategy is to create and/or modify a jsp in the action and on return
forwards to a result *which will forward to the just created or modified jsp*
you're welcome

Re: Struts w/Ajax with Struts again
The form will not be updated unless you refresh the values or the part of the page that displays the values you want to be updated. So you would have to manually do this processing some returned updated values in a json result, or by returning the result of a partial jsp which re-renders the part of the page that you want to be updated, and then replace the existing html (using innerHTML).

If I setAttribute(), the original value that was processed when the form first generated is all that ever shows.

RE: Struts w/Ajax with Struts again
apologies as i thought you were uptodate on the latest version
i assume you are implementing
public ActionForward execute(ActionMapping mapping,
ActionForm form,
ServletRequest request,
ServletResponse response)
throws Exception;
the ActionMapping mapping will call findForward which will
Return an appropriate ActionForward object that identifies the presentation
page to be used to generate this response, based on the newly updated beans.
Typically, you will acquire a reference to such an object by calling
findForward on either the ActionMapping object you received (if you are using a
logical name local to this mapping), or on the controller servlet itself (if
you are using a logical name global to the application).
its important to declare local variables in Action specifically:
controller servlet creates only one instance of your Action class, and uses
this one instance to service all requests. Thus, you need to write thread-safe
Action classes. Follow the same guidelines you would use to write thread-safe
Servlets.
Only Use Local Variables - The most important principle that aids in
thread-safe coding is to use only local variables, not instance variables , in
your Action class. Local variables are created on a stack that is assigned (by
your JVM) to each request thread, so there is no need to worry about sharing
them. An Action can be factored into several local methods, so long as all
variables needed are passed as method parameters. This assures thread safety,
as the JVM handles such variables internally using the call stack which is
associated with a single Thread.
For each request made of the controller, the method process(HttpServletRequest,
HttpServletResponse) will be called.
so keep the guts of the request processing in the Action process method
http://struts.apache.org/1.x/userGuide/building_controller.html
ActionMapping considerations:
use RequestActionMapping instead of SessionActionMapping
http://struts.apache.org/1.x/apidocs/org/apache/struts/action/RequestActionMapping.html

Hi Martin
Thanks, however I havnt migrate to Struts2 yet. What I was hoping for was a
technique to get all the session objects reprocessed upon return from the
Ajax call. I am unclear that if I do the mapping.getInputForward(), does
that force tomcat to reprocess and the jsp reprocess all the session objects?
I have also tried returning from the Ajax call with a forward to the page
and that doesnt force a redisplay of updated values. That should, correct,
it is no different than any other usage and with the json result being stored
in the header it will not matter for that processing.

better off setting it in the action
then access it thru ognl e.g.
#session.setSeeMe
http://struts.apache.org/2.0.14/docs/ognl-basics.html
if you want to see a bean described as
package package;
public class bean {
private String BeanParamName;
public void setBeanParamName(String BeanParamName
Re: Struts w/Ajax with Struts again
Hi Nils Martin
Thanks and I am sorry about being obtuse and I hope you will continue to make
this an edifying moment for me.
When I initially put up the form I code a value in the actionForm, myFormBean
as myFormBean.setSeeMe(firstTime) and put into the session with
session.setAttribute(fb00, myFormBean) I display this value on the form page
within a html:text with ...value=${sessionScope.fb00.seeMe}, and it shows
firstTime on the form. Good. I process the Ajax call in another Action, fed
with the same class of actionForm. No matter whether I remove the action form
session.removeAttirbute(fb00) or if I set it a different value,
myFormBean2.setSeeMe(fromAjax);session.setAttribute(fb00,myFormBean2). I
still see firstTime.
I am looking for the simplest technique that would reprocess the session
objects from the new values, regenerate the full jsp, ancilliary to the json
object I am setting, in the action processing the Ajax. Specifically I am
using the iterate tags to display a series of records and that is what I want
to be reprocessed and redrawn to the user with the new values that will be in
the session object set in the Ajax processing action.
I understand that actions should/must be thread-safe, I just want to reprocess
objects that are unique to state maintained by the session object. I am
suspecting this is not possible.

The form will not be updated unless you refresh the values or the part
of the page that displays the values you want to be updated. So you
would have to manually do this processing some returned updated
values in a json result, or by returning the result of a partial jsp
which re-renders the part of the page that you want to be updated, and
then replace the existing html (using innerHTML).

RE: Struts w/Ajax with Struts again
Hi Martin
Thank you. So I may be misunderstanding something. If I return to the Ajax
call with mapping.getInputForward() for the defined input attribute of that
action processing the Ajax call, should I see changes in the session objects
displayed? Because before I return I set an element in the
actionForm.setSeeMe(hi), set the session.setAttribute(actionForm, modified)
and I do not see it in the display. I am accessing that element with the
${seeMe} syntax. I am seeing the json results, but not what I put in the
actionForm. That is what I would organically expect to see. Can you clarify
this? tia.
