display master child records using jps,logic:iterate
Hi all, if we have a master/child relationship to show after execution of action/execute, how shld we create the beans to display this using jsp and logic:iterate ?? i tried creating 2 beans (one each for master and child) but it is difficult to match master record with child . The output needs to be like - 1Master rec first Child rec 1 child rec 2 child rec 3 2)master rec second child rec 1 child rec 2 child rec 3 and so on .. how this can be achieved using beans ?

scope and presenting realtime data
Hi, We are developing a web based interface (struts + jsp etc) for realtime monitoring of server cpu usage. We have written a bean that will contact the server and get the current cpu usage and return that value. I want to plot a line graph (using jfreechart) with the cpu usage in Y-axis and time in X-axis. The Graph need to plot the last 'N' values + the current value during each refresh. The issue is how to remember these last N values. I do not want to assign session scope for this object as the end-user might monitor for more than one servers and several users might be using the system at same time. How this situation is typically handled in the Struts+jsp environment. thanks regards -Ramudu - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: scope and presenting realtime data (fwd)
Why not store the info in the servlet context, using different keys for each server? That way if several users are all monitoring the same server they will be looking at the same set of data. Since the data is being multithreaded you will need to make sure you synchronize in the appropriate places for which purpose you would probably implement some kind of bean to store this data in an internal collection. You would probably want to merge the functionality of your polling bean with this storeage one, so you would be using one bean instance per server, with all users sharing these beans simultaneously. Id suggest that when the bean is asked to pull data for a particular server it checks to see that a certain period of time has gone by since the last poll. If not you wouldnt bother pulling another value to add to the set.(Id suggest at least a second, and more if you have lots of users). If two users ask for the information within a few milliseconds if each other there is little point doing an extra poll. By the time the graph is redrawn and hits the browser even the most current value will be many milliseconds out of date anyhow and it doesnt make much difference to a human! In terms of 'realtime' presentation you probably dont really want to have the browsers polling the server too much (though it would be easy to do with a javascript timer that refreshes the page), as all the requests will add considerably to your server load (especially since the charts need redrawing). If your setting a minimum polling period as suggested above you would probably also want to try and somehow cache the resulting chart images until such time as new data is available, such that several requests coming in rapidly (probably from different users) could all be serviced with the same image and cut the need to spend server time re-rendering the chart. Thats just my 2 cents worth though so theres probably many better ways of doing it. hth Andrew -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Wednesday, 26 May 2004 19:42 To: [EMAIL PROTECTED] Subject: scope and presenting realtime data (fwd) Hi, Can anyone suggest some approach for this issue. thanks regards -Ramudu -- Forwarded message -- Date: Wed, 26 May 2004 14:52:23 +0530 (IST) From: [EMAIL PROTECTED] Reply-To: Struts Users Mailing List [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: scope and presenting realtime data Hi, We are developing a web based interface (struts + jsp etc) for realtime monitoring of server cpu usage.

Re: New Struts tutorial in Struts Wiki
There are currently four flavours of Validator ActionForms, so IMO it would be good to say something about this. Your example shows using the ValidatorForm - the alternative is if someone wants to use Dyna forms and the equivalent is DynaValidatorForm, it would be good to show an example of this. Both ValidatorForm and DynaValidatorForm use the form name attribute from the struts-config.xml action mapping to find the validation rules from the validation.xml - there is an alternative to this, which is to use the action's path attribute from the struts-config.xml action mapping - ValidatorActionForm and DynaValidatorActionForm use this mechanism.

RE: Links relative to jsp not action in Opera
[The other problem here is in a cluster the server must be the virtual host fronting the cluster not the localhost, although this can be solved it's just an extra pain.] According to http://jakarta.apache.org/struts/userGuide/struts-html.html#base you can use two attributes from which one is server. I never tried this one, but it looks like you can enter your virtual host there, possibly after reading it from config file or so Default is request.getServerName(), not localhost. I'm not sure on how to use the html:base tag in the opposite manner, ie the href to be that of the struts action's path not the jsp's path? Indeed it seems impossible to create a base tag containing an action path instead of a jsp path, or at least it didn't work for me. I assume your jsps are not in the root? I once had difficulties with the base tag with jsps not in the webapp root. I ended up placing the jsps in the webapp root. Not sure if this is an option for your project, but maybe you can do the same? I have to warn you that I don't know about tiles, nor can I tell you if that makes the situation different. Just trying to give you hints :-) Jeroen - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: scope and presenting realtime data (fwd)
neither request nor session. the recommendation was to use the application context (also known as servlet context) This is one context object FOR ALL servlets und users within the same web-application. It would be shard between ALL users of the web-application, so the overhead of keeping it alive even when no user is accessing it, is not exagerated. Else you will have to program (or search for) a caching mechanism with active object invalidation. As this needs to be perfectly synchronized (attention: not over-synchronized), is is not an easy task. hth Alexander -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Mittwoch, 26.

Thats just my 2 cents worth though so theres probably many better ways of doing it. hth Andrew -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Wednesday, 26 May 2004 19:42 To: [EMAIL PROTECTED] Subject: scope and presenting realtime data (fwd) Hi, Can anyone suggest some approach for this issue. thanks regards -Ramudu -- Forwarded message -- Date: Wed, 26 May 2004 14:52:23 +0530 (IST) From: [EMAIL PROTECTED] Reply-To: Struts Users Mailing List [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: scope and presenting realtime data Hi, We are developing a web based interface (struts + jsp etc) for realtime monitoring of server cpu usage.

RE: Links relative to jsp not action in Opera
I'm not sure on how to use the htmml:base tag in the opposite manner, ie the href to be that of the struts action's path not the jsp's path? Are you sure you want to have the action path in the base href instead of the jsp path? I would think that as you write the relative links inside the jsp, you also want to make the relative paths relative to the jsp? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: How to renderize a image?
you can use whatever image tag you want. The real catch is that you will need and action that pulls the info from the db and writes it to the OutputStream in the response. The have the execute method return null. You might end up with a tag that looks like... img src=c:url value=/CreateChart.do/ This is if you use jstl otherwise html:img action=/CreateChart.do / might work but I am not sure. nathan On May 26, 2004, at 6:57 AM, Paulo Rezende wrote: Friends, I have a image in Oracle Blob field and i want to renderize it my jsp.

My form property is a Blob, but i guess that this tags dont support this Hi, First remember how images work in HTML. the img src=... attribute is treated as an href, so there are actually two separate HTTP requests: one to render the JSP and one to fetch and display the image. The only thing that changes if your image is stored in an Oracle BLOB is, instead of html:image pointing to a file resource, it has to point to a servlet that you write yourself. The servlet fetches the BLOB from your table, sets the Content-Type properly (image/gif, image/jpeg) and writes the bytes to response.getOutputStream. One thing to remember is, you _can't_ retrieve images from within an Action because you are only allowed to call response.getOutputStream once during the request and Struts' ActionServlet already appears to do that. So you have to write an actual servlet.

Re: How to renderize a image?
It's an error to call getWriter after getOutputStream (or vice versa), but I don't think it's an issue to call getOutputStream multiple times. Although, even if it were, I really don't think Struts ever calls getOutputStream. At least not in 1.1.

I once had difficulties with the base tag with jsps not in the webapp root. I ended up placing the jsps in the webapp root. Not sure if this is an option for your project, but maybe you can do the same?

Yes you'll need separate db calls. Images are always separate urls and are
not 'embedded' into the html.
Your picture servlet will look something like below so it's not like there
is really a lot of extra work involved.
String format = ...;
byte[] data = ...;

Passing ActionForm along on the request
Is it possible to call an Action which pre-populates a form, forwards on to a JSP page which displays the form values for the user to change, and then submit back to an Action that will contain the form value? We're running into a scenario where we prepopulate the Form in 1 action and set it onto the Request. The jsp displays some of the values so that they may be modified, and then submits back to a second action where the Form is to be populated. When the form is submitted to the 2nd Action, the ActionForm is reinitialized, and ends up throwing an exception in the BeanUtils.populate method because an object on the form is null. We've found that the scenario works fine when using Sessions, but runs into issues when using the request. Here's a sample struts config: action path=/actions/MyAction type=actions.MyAction name=myActionForm scope=request validate=false forward name=continue path=/actions/MyAction.jsp/ /action action path=/actions/MyActionSubmit type=actions.MyActionSubmit name=myActionForm scope=request input=/actions/MyAction.jsp validate=true forward name=continue path=/actions/MyNextAction/ /action We already have 1 solution (using sessions), but given the fact that we're going to be working in a load-balanced environment with multiple Tomcat instances, we are trying to use the session sparingly. Another solution that I just thought of would be to replicate all the values of the Form as hidden values on the JSP page so that they would be repopulated on the submit. This would be slightly annoying, but is a viable solution. My question is, is there another solution that works as clean as sessions but uses the request? _ Jeremy Nix Senior Application Developer Southwest Financial Services, LTD.

RE: Passing ActionForm along on the request
I presume the element that's throwing the NPE is one of the elements that the user cannot change. I presume this because let's say for the sake of argument that all the fields of the ActionForm were on the screen, then what you describe should never happen. Your dealing with the classic stateless nature problem of the web in general... you can either put it in session (or some other persistent storage on the server) or you can pass the information to the view, which wil pass it with the next request (i.e., hidden form fields, as you alluded to). Putting any object in request definitively means that it should NOT persist between requests, that's the whole point, so if you have something you need to persist, as you do here, those are your choices basically, either session or data passing between JSPs. If security is an issue you can get into applets or (God forbid!) ActiveX controls, then do all your data passing through them (and this might not even work with applets since they will probably be loading with each page load, so there's no persistence there either, so ActiveX becomes the option, but then your talking IE only, without buggy plug-ins anyway, so really neither is much of an option anyway).

Dear All, Thanks for all your feedback. Based on the discussion i derive following conclusions. please comment on their accuracy. 1. A Data Storage object (Say a HaspMap with the server name as a key and the N value data object as value are stored along with the last updated time) -- we are not going for database to save time on I/O and do not want to deal with stale data in database. -- 2. A cleaner thread will wake-up periodically, and remove the server entry which is not being used for the last 'X' minutes -- This we need to do as we are having large number of servers to be monitored -- 3. For each request the bean class need to a. poll and get the current value b. get the stored data object for the server c. if the object exists, add the value and drop the oldest sample if size becomes N+1 d. if object does not exist, create with the current value e. update the value in data storage object thanks regards -Ramudu On Wed, 26 May 2004, Irfandhy Franciscus wrote: My advice may sound out of the context, but how bout actually storing each last N value to a database. this way you can even have an archive of the Last N value.

Whats the best way to do so? Redefine the reset() method in each ActionForm and call it from the action? Or hold the values and do: form = new ActionForm(); in the action call?

Q: Can I have multiple ApplicationResources from the same locale?
This may be a RTFM situation, but I didn't want to take a break and try it and then after a hour find out it didn't work so I was hoping (while I was coding) someone could let me know if the following is legal: Situation: I have an ApplicationResources_en.properties file that represents the English locale of my app. This file is getting huge (to say the least) as I've internationalized pretty much all the text in my entire app. I was hoping to break out this file into logical units that collective represented the English locale, for example: ApplicationResources-User_en.properties ApplicationResources-Product_en.properties ApplicationResources-Module_en.properties ApplicationResources-Administrator_en.properties. and move the corresponding key/value strings into the appropriate .properties files.

[JSTL] accessing rows by index
Hi all,
in my Struts application I can access result collection from sql:query
with the forEach loop. When I try access one single row by index, it
fails. Right now I solved this with defining a forEach loop where begin
and end are the index I want to access.
This looks like this:
c:forEach begin=1 end=1 items=${xyz.rows} var=yxz
...
/c:forEach
In my opinion there should be an easier way. Can anyone give me a hint
or a piece of code how I have to access my rows by index?
Thanks,
Axel

Re: How long are your struts-config files? Should I worry about performance?
Ok this was what I was wondering about (runtime). I didn't know if the hashtable with all the actions in it was going to be too big or something to that effect. Thanks for the feedback! On Wednesday 26 May 2004 12:51 pm, Hubert Rabago wrote: If your concern is with the physical size of your file, you can break down your struts-config into multiple files with your entries spread among them. What I do is have a main struts-config.xml containing my global values and all plug-ins, then have several struts-config-nnn.xml files for nnn-related forms and action mappings. Can't say I've tried profiling the effect of having a large number of mappings as a result of a large config file. I'd imagine there'd be some difference at the startup of the app while Struts parses your config. Overall, though, I wouldn't really worry about it. In most cases, I'd say the effect at runtime, if any, would be negligible in terms of speed. --- Riyad Kalla [EMAIL PROTECTED] wrote: I'm curious what the size of some of the verteran programmer's struts-config.xml files are.

version confusion
I'm a recent convert to java (from micro$oft... sh) and i'm still trying to understand which versions of which products work together. I just got Tomcat 5.x, which implements Servlet 2.4 and JSP 2.0. Does it matter if I use Struts 1.0, 1.1 or 1.2 with this? Why? How does the version of the JRE affect things? How do I know which version of the JSTL I need? Is there some good reading on these topics somewhere? (A document that can explain how all these products work together and how the version of one affects the version of another?)

Re: version confusion
Brian, This can definately get confusing if you are just thrown into the mix. Tomcat 5 is definately the right way to go, its faster, more stable and supports newer specs. Struts, IIRC, is designed to only need the Servlet 2.2 and JSP 1.0 or 1.1 spec, it was meant to be super-compatible, soyou should be safe. There is information on the Struts page (under future direction) where it explains that the next Struts 2.0 release might change to require Servlet 2.3/JSP 1.2 I believe it was. As far as JSTL, just get the newest version possible. JSTL it a set of taglibs, and JSP has supported taglibs for a while. But if you want to get fancy with the Expression Language support in JSTL, then you will need a container that supports Servlet 2.4 spec (which Tomcat 5 does just fine). I believe I've left out gaping holes of information, and may even be wrong, but AFAIK this is the gist of the version information you need. Generally going with the newest stuff you can find is pretty safe, especially with Jakarta projects (stuff comming out of apache group). They have one of the strictest (I love it) release cycles I've ever seen when it comes to shipping stable stuff. I hope that helped atleast a little, Riyad On Wednesday 26 May 2004 01:31 pm, Barnett, Brian W. wrote: I'm a recent convert to java (from micro$oft... sh) and i'm still trying to understand which versions of which products work together.

RE: How long are your struts-config files? Should I worry about performance?
My config file for a project I'm currently working on is 7k, and that's NOT counting comments (something like 16k counting them - I'm a comment freak). Since it's only parsed once at startup, I wouldn't be too overly concerned about performance. Yes, your talking about a lookup for each request, and I'm not familiar with how it's stored internally (just a HashMap maybe?), but I wouldn't suspect it's a huge concern. I can't speak to how typical that size is of course, but it's one example. I should also point out that the app I'm referring to was originally built on a homegrown framework (I didn't write it, so don't laugh at ME when I tell you this)... it used a very convoluted mapping XML file structure, much more complex than struts-config, and the that version of the file was 43k! Again, NOT counting comments! And to make matter worse, this file was actually parsed WITH EACH REQUEST!! But, and here's where I get to a point (aside from the fact that those that wrote that framework didn't know their a** from their elbows)... performance even under those conditions with a halfway decent load (50 concurrent users at any given time on average) was perfectly acceptable. And it wasn't a monstrous server either (Dual P2-550's with 1G RAM and a SCSI array internally). So, I wouldn't be too concerned with the size of your struts-config, unless someone else has reason to disagree. A couple of K wouldn't concern me.

Can actions in module B have access to the ones in Module A ? i.e. can I lookup a Struts Action defined in Module A from doing a lookup in an Action defined in Module B vice versa ? Do modules in Struts follow any hierarchial structure ? Ashwin. __ Do you Yahoo!? Friends. Fun. Try the all-new Yahoo!

Re: How long are your struts-config files? Should I worry about performance?
I'm still working on the conversion after two weeks. It took me probably two days to identify all the changes that had to be made, and then about 5 days of mostly search-and-replaces, and ever since then dealing with the unexpected problems during testing. One of the tough parts was that this framework only allowed a single destination page mapped to an action, and if the flow of your logic coming out of your actions (app controllers they were called in this thing), you actually had to throw a specially-constructed custom exception class that the controlling servlet would use to redirect. Worse still, the destination was actually encoded into the exception, not simply defined in an XML file, so you had what would be in struts-config actually hardcoded in some places in the controllers! And that was just the start of my misery! :) I don't know if the app is any happier being on Struts, but *I* sure am! :) From: Riyad Kalla [EMAIL PROTECTED] Reply-To: Struts Users Mailing List [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Subject: Re: How long are your struts-config files?

Yes, your talking about a lookup for each request, and I'm not familiar with how it's stored internally (just a HashMap maybe?), but I wouldn't suspect it's a huge concern. I can't speak to how typical that size is of course, but it's one example. I should also point out that the app I'm referring to was originally built on a homegrown framework (I didn't write it, so don't laugh at ME when I tell you this)... it used a very convoluted mapping XML file structure, much more complex than struts-config, and the that version of the file was 43k! Again, NOT counting comments! And to make matter worse, this file was actually parsed WITH EACH REQUEST!! But, and here's where I get to a point (aside from the fact that those that wrote that framework didn't know their a** from their elbows)... performance even under those conditions with a halfway decent load (50 concurrent users at any given time on average) was perfectly acceptable. And it wasn't a monstrous server either (Dual P2-550's with 1G RAM and a SCSI array internally). So, I wouldn't be too concerned with the size of your struts-config, unless someone else has reason to disagree. A couple of K wouldn't concern me.

I don't know if I should really start worrying about performance/other issues, or if this is normal and I should smile and keep working. Thanks!

Re: Struts modules question
I wasn't involved in implementing modules, but from discussions and experience, my understanding is that modules are conceived as pretty isolated components, despite the fact that they are in one web application. It is possible to switch between modules using the SwitchAction, for instance, and the JSP tags have some support for indicating paths in alternate modules (which has mostly happened since the 1.1 release). In my development, my primary motivation was simply to compartmentalize the config files. Once I learned that you can specify any number of struts-config.xml files in web.xml and, similarly, you can specify any number of tiles and validation files in the plugin configurations for those components, I haven't used modules. I've become quite fond of a pattern like this: /WEB-INF/sectionA/struts-config.xml /WEB-INF/sectionA/tiles-definitions.xml /WEB-INF/sectionA/validation.xml /WEB-INF/sectionB/struts-config.xml /WEB-INF/sectionB/tiles-definitions.xml /WEB-INF/sectionB/validation.xml /sectionA/Foo.jsp /sectionA/Bar.jsp /sectionB/Baz.jsp /sectionB/Qux.jsp /sectionB/Quux.jsp This parallelism keeps any individual config file from getting too large while providing a pretty clear rule for where to go looking for the various components of a solution. It can sometimes be unclear how to section things, but mostly it's very straightforward. I think many developers begin using modules expecting more interoperability and perhaps hierarchical configuration. Since Struts is open source, there's no reason people couldn't build that out -- but I've found that I don't actually need modules, so I don't use them.

Date: Thu, 27 May 2004 02:12:37 + (UTC) Hi - I deployed a web application this week that was written in Websphere 5.2, Struts 1.0 - One of our users is running IE 5.2 (which is apparently the latest version on MacIntosh). One of my forms, when filled in with data, and you submit, nulls out the fields. Then, my Struts validation setup, returns errors to screen saying the fields are null and required, then, when you look at the screen - they were nulled out during submission process. That is, they were there before we clicked submit. It appears to me that this is only on the form where I have validation on the action tag in struts-config - as previous screens use form handling but, are not configured for Validation. Again - this same application works fine on all Windows platforms, IE 6.0 - Netscape 7.1, etc. Any ideas? Could this hopefully be a configuration setting on the browser? Or, am I forced to pull out my Struts Validation from this screen???

RE: Strategies for Clearing Session Objects
I've only really been concerned with such a thing in one instance, and that was because we were caching some returned ResultSets, and they could be very large... What I wound up doing is wrapping each ResultSet in a HashMap, and I had two other elements, one storing the datetime stamp the object was created, and another specifying how long the object shoud live... Then, on every subsequent request I would check those values and null out any object older than it's specified time to live. It's not the most elegant solution, but the usage pattern of this particular application made it rather effective. I also considered starting a daemon thread when the app started up that would periodically do cleanup chores, but I never got around to doing the research to see if it could gain access to the session information. I've used daemon threads in a number of cases for periodic tasks when I wanted the tasks to be intrinsically linked to the app (i.e., started and stopped with it, dependant on some server resources shared with the app, etc.), but never for cleanup tasks like this. My bet is it's possible, but most probably server-specific, so I'm not sure I'd want to do that as I hate being tied to any particular app server. Another option I considered but never tried to implement that SHOULD work is to write custom classes that will be stored in session that extend Thread. Then you can have a member that tells how long it can live for, and just kill it in run() when it's time. I've never done this because the idea of spawning all those threads sounds obviously bad, but again it comes down to the usage pattern of the system I suspect... If you maybe have a ResultSet that you want to keep reusing if it exists, but you want it to always refresh after five minutes for instance, and you know your not going to have so many concurrent sessions that the number of threads wouldn't kill you, it might be a good way to go. I'm not sure what number of threads starts to be cause for concern, it has a lot to do obviously with server resources and expected system load, but this idea actually had quite a bit of appeal to me, it was just quicker to implement what I wound up doing (and time to market was the primary driver, as it usually is, and what the business wants and when tends to trump design work unfortunately).

Re: Dynamically sized form using dynavalidator
... and also, you're probably going to need to look into populating an
empty array or List called from your reset method. Pain in the butt, but
there is a lot in the archives about ways to handle it. For testing
puprposes to start with just give the form session scope which will
avoid the problem (but not necessarily the best thing in the world to do).
Rick Reumann wrote:
I haven't tested this and it's late.. but your form property is cart
not item.. so if you are going to use JSTL (and not the nested tag which
is actually easier) it would be something like...
c:forEach var=item items=${cartitems} varStatus=status
html:text property=cart[${status.index}].unitPrice
value=${item.unitPrice} /br
/c:forEach
Using the nested tag it would be:
nested:iterate property=cartitems
nested:text property=unitPrice /
nested:text property=quantity /
/nested:iterate

The processing action could then retrieve the dynaform and the changed

Subject: Dynamically sized form using dynavalidator
I have defined a form that will grow dynamically at runtime. The problem
I'm having is that the values entered in the form do not save. The form
pre-populated just fine. I have an action that delivers the form and
another action that processes the form.
Here's the strutsconfig:
form-bean name=shoppingCartForm
type=org.apache.struts.validator.DynaValidatorForm
form-property name=cart
type=com.je.common.ShoppingCartItem[]//form-bean
actionpath=/propmgmt/viewcart
type=com.je.struts.action.pm.ViewCartAction
name=shoppingCartForm
scope=session
input=
validate=false
forward name=viewcart
path=/tmpl_propmgmt2.jsp?pageleft=/propmgmt/leftmenu.jspamp;pagecenter=/pr
opmgmt/viewcart.jspamp;pagetitle=home.title.key /
/action
actionpath=/propmgmt/checkout
type=com.je.struts.action.pm.CheckOutAction
name=shoppingCartForm
scope=session
input=
validate=false
forward name=checkoutform
path=/tmpl_propmgmt2.jsp?pageleft=/propmgmt/leftmenu.jspamp;pagecenter=/pr
opmgmt/checkout.jspamp;pagetitle=home.title.key /
/action
=
Here's the JSP:
html:form action=/propmgmt/checkout.exe method=post scope=session
table border=0 width=96% class=listings
trthShopping Cart Items/ththPrice/ththLength of
Ad/ththItem Total/th/tr
c:forEach var=item items=${cartitems}
tr
tdc:out value=${item.id} //td
tdhtml:text name=item indexed=true
property=unitPrice
size=6 //tdtdhtml:text name=item
indexed=true
property=quantity//td
%--tdhtml:text name=total value= size=7//td--%
/tr
/c:forEach
/table
html:submit value=Proceed to Checkout--/ /html:form
Like I said, the form prepopulates but when I enter new values I don't
see
them in the checkout action. The original entered values aren't getting
overwritten.
===
Here's what the gen'd HTML looks like:
form name=shoppingCartForm method=post
action=/rentworx/propmgmt/checkout.exe
table border=0 width=96% class=listings
trthShopping Cart Items/ththPrice/ththLength of

AW: Set DynaActionForm to see values in textfields...(form-page)
Oh sorry, the HashMaps works correct, BUT only if you DONT use a
DyaActionForm Formular.
If you use the Validation you have to use also a DynaActionForm-Session
Object (or request-Object).
now i have find something which helps me!!

into the database or
- put really new Values into the Database
Thanks for your help!

Hi Johannes ,
Are you sure this code works ??
code
String field1 = (String) PageA.get(field1);
String textfield2 = (String) PageA.get(textfield2);
.
DynaActionForm PageB = (DynaActionForm)
session_automatic.getAttribute(PageB);
String textfield1 = (String) PageB.get(textfield1);
String textfield2 = (String) PageB.get(textfield2);
/code
Have you checked the text field values ? I feel only one form would be
submited .
You shoud be using the form in execute method and I feel One action is
related to one form , so you would get only values of one form .
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
RegistrationForm regform = (RegistrationForm) form;
}

Hello,
I have created more than one form-pages with struts. After validation
i can read the values in the Action with:
-
HttpSession session = httpServletRequest.getSession(); DynaActionForm
PageA = (DynaActionForm) session_automatic.getAttribute(PageA);
//This is a DynaActionForm-Object in the Session
String field1 = (String) PageA.get(field1);
String textfield2 = (String) PageA.get(textfield2);
.
DynaActionForm PageB = (DynaActionForm)
session_automatic.getAttribute(PageB);
String textfield1 = (String) PageB.get(textfield1);
String textfield2 = (String) PageB.get(textfield2);
.
--
All works!
Now i would like to edit one entry from the Database.
So i have to define the Sessions and after the definition i go to the
form-page. Than the fields must have the values from the Database.
But this doesn't work!!
My Code:
---
HttpSession session = httpServletRequest.getSession(); DynaActionForm
PageA = new DynaActionForm(); PageA.set(textfield1,My Value);
PageA.set(textfield2,My Value);
DynaActionForm PageB = new DynaActionForm();
PageB.set(textfield1,My Value);
PageB.set(textfield2,My Value);
//Define a DynaActionForm-Object in the session
session.setAttribute(PageA, PageA); session.setAttribute(PageB,
PageB);
-
This breaks at the line PageA.set().
The ERROR is java.lang.NullPointerException
Can you help me?
Thanks!
