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?

RE: Struts w/Ajax with Struts again
Hi Martin
Yes, I did in the line defining both the initial action to bring up the form
and the action tasked with processing the Ajax call. Also I put in the Ajax
processing action specific setSeeMe("fromAjaxAction") and set that in both the
request and the session objects. Still nothing but what the first default
process set. The changes set in the Ajax action did not show no matter what
life-cycle object they were put in nor what scope the action was defined. This
should not be the case, correct? If I set the scope to request, and if I set a
change in a actionForm and set it in the request, I should see it on the
forwarded form. tia.

Re: Struts w/Ajax with Struts again
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 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
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 hth Martin Gainty __ Jogi és Bizalmassági kinyilatkoztatás/Verzicht und Vertraulichkeitanmerkung/Note de déni et de confidentialité Ez az üzenet bizalmas.

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).

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.

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.

Struts w/Ajax with Struts again
Hello I am able to use an Ajax call to a struts action and with getInputForward() get the get the data back. (With prototpye and json, very, very elegant). I am now realizing that I have cases where I want to reprocess all components, i.e. I want the actionForm to be updated and the jsp recalculated, I want the session objects to be reprocessed so my iterate tags will show the updates, etc. I understand how with getInputForward it doesnt happen. If I setAttribute(), the original value that was processed when the form first generated is all that ever shows. A simple findForward() does not force the reprocessing,ie still the original values of the actionsForm members. Is there a way to force a complete reprocessing the jsp from within an action? tia.

Re: {Maybe OT} Ajax with struts
When you do a post you need to open the connection like so
server.open("POST",URL,false) where server is your xhr object.
To send as a post you need to encode your name value pairs to be sent and pass
them as the body of the request.
server.send(name=value&pairs=go&here=true); then they will show up on the
server as parameters instead of attributes.

Yes, that was the problem. I changed the POST parameter to GET in http.open(); and its working. Keeping it POST and passing the parameters in send() does not work. Anyways, making it GET works and thats what I need. But what could be the problem? regards, vijay.

If you use POST for your XHR, you must specify request parameters in XHR.send(...) instead of appending them to action address. If you use GET, well, your URL seems ok, I would pass null in XHR.send(...) but I am not sure that this is the problem.

{Maybe OT} Ajax with struts
Hello, I used AJAX to fill details for a corrosponding selected value listed in a combo box. So for a particular registration number, the details of the vehicle are filled. On the onchange() event of the combo box, I am calling a JavaScript function which creates a XmlHttpRequest with the url = "RegDetails.do?action=populate" where action is a DispatchAction parameter. I am working in Websphere Application Developer Studio and its working great in it. But when I deploy the application in Websphere AS 5.0, the AJAX stuff does not work. Pre-population of the jsp form works great (which is also based on DispatchAction - I give http://localhost:9080/dpims/RegDetails.do?action=populate). Only the AJAX stuff does not work. I get the following error [4/11/06 12:07:14:250 IST] 5fbb0406 DispatchActio E org.apache.struts.actions.DispatchAction Request[/RegDetails] does not contain handler parameter named action I am not able to figure out the problem. regards, vijay.

If your results aren't going to be large you could do a greedy query on the first letter, and store the results as a javascript array (sending the results as a javascript array may also be easier than sending an xml). When a keyup happens on subsequent letters you could search the javascript array rather than calling an action. There would be a little more work on the javascript side, but you'd bother the server less.

Re: ajax with struts
Hello, The first thing I would suggest is this is one of those cases where the X in AJAX probably isn't appropriate. Remember that there is NO requirement to use XML when doing AJAX (although I suppose it isn't AJAX then strictly speaking). Take Google Suggests for example. They are not passing back XML, they are actually passing back, if memory serves, a chunk of Javascript that they execute. I seem to recall it being just a Javascript array that is used to populate the dropdown, but I may not have all the details right. The point though is that it isn't XML. Aside from that, one thing Google does too is they actually throttle the requests. I don't have all the details, I just heard it explained once at a user group meeting, but basically, the faster a person types, the LESS requests go across, and that is dynamically calculated. Another thing you can do is write the code such that the request will only fire X number of milliseconds after the last keyUp is received. Maybe wait half a second after keyUp, and if a keyDown fires in the mean time, you reset the counter. You would have to balance things so that the delay doesn't lead to a poor user experience, but I think that can be done. (I just saw Rick's reply as I was typing this, he makes the same basic suggestion). On the server-side, if possible, implement some sort of caching. Without knowing what kind of data you are using in your autocomplete, I can't make any specific suggestions. But basically, if you can cache a subset of the most frequently used data on the server, then you won't have to hit the database as often. Maybe its even possible to cache the entire database contents on the app server? At the end of the day there are two considerations: how many requests you make of the server, and what the server actually has to do to service the request. If this is a LAN/WAN application, you will find the greater bottleneck is almost certainly what the server has to do. If it's Internet-based, the opposite may be true. One bit of advice is to not assume you have a problem at all! In this case you may, but do some basic testing first. I've seen people assume that AJAX is horrible for network traffic when just the opposite wound up being true. Then again, I've seen people who assumed just the opposite and got burned :) Frank Joel Alejandro Espinosa Carra wrote: Hello all, I'm coding a simple action that retrieves some data from the database in order to create an xml object for an ajax-based autocomplete field, I'm worried about the load of the database beacuse this action is called from a javascript event "onkeyup()" this means that the action will be executed every time when user press a key in the field, is there an other way to do this in order to increase the performance? pd. this is not a must-have requirement but I want to know what is the best way to do this.

When you capture onKeyUp() start some sort of timer, so that the user has to pause for at least maybe 2 seconds(?) before you hit the server. This way if the user is just typing along quickly that ajax event won't fire. -- Rick http://www.learntechnology.net - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
