RE: dynamic javascript forms
I'm pretty sure you can do it if the text inputs are set up in the form as an Array of Strings and if you create your input tags to match what struts would expect from an array. If you do that, you can have your javascript create the fields dynamically as you said. It sounds like you tried this and it didn't work for you, but I would think it's probably just because you either didn't use an array setting up the action form, or you didn't create html input tags that matched what struts would have created if you used html:input. -Rob -Original Message- From: mike barretta [mailto:[EMAIL PROTECTED] Sent: Monday, March 15, 2004 2:35 PM To: [EMAIL PROTECTED] Subject: dynamic javascript forms thanks in advance for any help... i have a form where i let the user choose how many text input fields they want and then via javascript, the inputs are displayed. ex: user has a box to make a choice of 1-10. after selection is made, the onChange event will fire and write however many text inputs on the screen using the innerHTML property. my problem is that since javascript changes the screen at runtime, i can't use to capture the text from the form because it isn't being interpreted by struts. if the javascript uses the standard tags, it seems like my actionform doesn't get populated with the data. so, anyway to do this without having to submit the form after the user selects how many inputs they want? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Fundamental Struts Concept
Ed, I'm not sure I understand your question exactly, but I'll answer the best I can. The only information that is sent to the client is the HTML that you see in the browser. The JSP gets converted to a servlet and the servlet just writes to the HTTPResponse, not the HTTPRequest. The "request" you are referring to is gone once the server sends a response. The JSP that builds the form can make use of as much data as is in the request, as it is all stored on the server side as you said. The new ActionForm the that is created after the user submits the form, from the HTTPRequest that the client's brower created, is indeed new and does not have access to any previously submitted client values unless they are 1. Persisted in some persistent storage 2. persisted in the user's HTTPSession, or 3. we included in the JSP as hidden fields (and presumably also the new action form). Does that help answer your question? -Rob -Original Message- From: Ed Tornick [mailto:[EMAIL PROTECTED] Sent: Sunday, March 14, 2004 3:32 PM To: [EMAIL PROTECTED] Subject: Fundamental Struts Concept Let's assume you have a Action Form with much data, including lists (you are using nested tags for example). When you create the Action Form you load it up with the data from your data source wherever it is. Let's also assume that you have set the action path in the configuration file so that the scope of this form is request. If the jsp on the server that is going to create your form on the client has only a few of the fields from the Action Form then how much data is actually sent to the client in the httpRequest? The reason I ask is that since it is my understanding that either a new Action Form is created when the user submits the form or if one already exists it is "reset", how can the Action Form have all of the original data, including the one or 2 fields the user just submitted? If the scope was session then it would make sense to me that the data would still be on the server and the users input would just modify a few fields.. but when it is request scope...This is what I don't understand.

There are different ways of implementing a secure site, and many variables
involved.
When you say you want to see if the session is "valid," are you talking
about name/password authentication, or some other session attribute?
If the former, you can implement a standard J2EE security model in the web
app deployment descriptor (web.xml), specifying which user roles can access
which pages (such "*.do"), and exempting specified other resources (e.g.
"login.do"). This will automatically prevent users from accessing pages
without being authenticated first, and also enable you to configure session
timeouts easily. It's also an easy, central, and standard method of
configuring security, and fits in neatly with the roles-based configuration
in the Struts config file. Your options would work as well, but wouldn't be
very flexible or easy to manage, especially if you expect the application to
get big.

The action can do any setup for the jsp page, such as retrieving any collections you may need to populate dropdown lists in the page.

RE: [OT] - Request against Session
Mark, My interpretation of that comment was that if a user has two windows open and are going back and forth between the windows, the system may use information from one window to update the information in the session that actually relates to the old window. This would be a pretty poor design, but it's the only interpretation I can guess. So the following could happen: 1. User chooses to edit order A. 2. Order A information is stored in the session and user is taken to an order edit screen. 3. User chooses to edit order B in a new window. 4. Order B information is stored in the session and user is taken to an order edit screen. 5. User goes back to edit screen for order A and adds an item. 6. Because the session has Order B info in it, the info is either added to Order B (instead of the intended Order A) Seems to me a pretty easy thing to check if the info they are updating relates to the info in the session, but that could be just me. -Rob -Original Message- From: Mark Lowe [mailto:[EMAIL PROTECTED] Sent: Friday, February 13, 2004 11:22 AM To: Struts Users Mailing List Subject: Re: [OT] - Request against Session Am i to assume that there's no issue then ? or am i being too stupid to warrant a response? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Can you send the log file of the error you get running the action class you

RE: [OT] - Request against Session
Shirish, I'm not knocking the "workflow" concept, my only point earlier was that someone shouldn't think it provides any real difference from session storage except that it will attempt to automatically clear the session when they leave that "workflow" and they won't have to put that logic in. It's a good idea, but this latest message indicates that it limits its use to applications that only allow a single "workflow" at a time. I've worked on many applications where there may be two or three valid workflows open for a user at once, for example a help desk application where the operator may be working on one issue and then need to open a new issue (in a new window) for an incoming call in the middle of the current workflow, they are both valid and neither contains "stale" data. -Rob -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Thursday, February 12, 2004 10:50 AM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: RE: [OT] - Request against Session If the user has multiple windows open all sharing a session and does different things in different windows things get really fun.

The only reason not to use getParamter to get hidden form variables is to
make sure you are doing things in a Struts friendly way. Technically,
"request.getParameter(...)" will return any value that is in the form or in
the request url as a parameter. They are both treated the same way.

Subject: RE: [OT] - Request against Session
When a browser first requests a page from a web server, the session is
created, so as Wendy said, "it's always there". The creation of the session
has nothing to do with whether the user is authenticated/logged in or not.
This is the way I understand it.
If you are set on using hidden variables here is a bit of info:
Using a hidden variable on a jsp page in Struts is pretty straightforward.
First, you add a variable to the formbean being used on the page with
corresponding setter/getter methods. Then in your jsp page, put something
like this in your form:
When the form is submitted, Struts finds a myFormBean object in the
appropriate scope (or instantiates a new one) and stuffs the value of the
hidden variable into myFormBean (using setter method). In other words, it
treats it like all the other form variables by calling the setter methods of
the formbean.
Then in your action class, you can reference the variable using the getter
method of your formbean.
For multiple pages, you'd have to follow the above guidelines on each page
and most likely programmatically call the setter method in your action
classes between page calls.
Don't use getParameter() to try to get hidden form variables. getParameter()
looks for parameters appended to the request URL --
http://www.myhost.com/do/myAction?param1=1¶m2=2. getParameter() will
give you access to param1 and param2.
You can also very easily access the session variables in your action class
like this:
request.getSession().getAttribute("sessionVarName")

how would I store it in the hidden form variable. I think if I store it in

RE: [OT] - Request against Session
Using the session is certainly a possibility, I for the most part, take the opposite approach. Generally the only objects I store in the session are objects that are going to be accessed throughout the entirety of the user's access to the site, stuff like authentication information and role information. I usually will use hidden form fields to carry information from one page to the next, but it's usually a small amount of information such as the keys for objects that may be needed for a next page. I also find that if the entire application is architected so that all the information an action needs is in the request as parameters, it becomes truly simplistic to rearrange the workflow or add links to existing pages in places you might not have expected them originally because the call requires nothing more than the correct request parameters. -Rob -Original Message- From: Mark Lowe [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 11, 2004 4:45 PM To: Struts Users Mailing List Subject: Re: [OT] - Request against Session There was an interesting posting the other day on this, I tend to stick stuff in the session because I cant be arsed messing around.

But IMO thats for the folks you build the JVM's to worry about. If you want something to persist beyond the request then I suggest put it in the session. By the time you've messed around trying to avoid this you could have brought more hardware to deal with the problem. I'd say same as wendy, although look back if anything breaks. IMO storing values as hidden form values is ugly, I'd use it as a hack if using session breaks anything (which is doubtful) just set stuff to null when you're finished and hope the garbage collector comes along.

You might want to try something like velocity so you can store the text of
the e-mail as a template and use velocity to insert the dynamic content.
If there are really only a few simple fields, I would store the text in the

replace tags like {ORDER_ID} and {USER_NAME} with the order id and user name
before passing that message to the mailer.

This is kind of off topic as it is not really struts related, but somebody

We have our application sending emails to users at some points and it is
working fine. The problem is that we have the email message hardcoded into
the Java, which we would like to avoid either by storing the message in
application.properties or our database. This would be easy, except all of
the messages contain user-specific information like their name or phone
number or order id or something like that.
Anybody have any ideas (or links to programs!) that can read in an email,
replace the information it needs to from the db, and send that to the user.
I could obviously write something myself to do it, but wouldn't want to

Turns out this is hard to search for too - email is not a search term that

RE: retreiving the labelProperty of an option tag
That's correct, the form is only going to submit the value not the label for the option. You might use javascript to populate a hidden field with the label so it gets submitted, if you really wanted to, but it would be much easier to just look up the label in your action using the value you received in the form and the collection that populated the list. -Rob -Original Message- From: Vinicius Carvalho [mailto:[EMAIL PROTECTED] Sent: Friday, January 23, 2004 7:30 AM To: [EMAIL PROTECTED] Subject: retreiving the labelProperty of an option tag Hi there!

RE: AW: Form is not submited - nothing happens?!?
Are you sure you are not getting any javascript errors? The best place to
debug something like this is to use Mozilla.
If your tag is resulting in an input field with the name
"submit" you are going to get an error that tells you something like "submit
is not a function".

HI,
the 'submitFunction()' is being called by my

really called. The alert() is done but not the submit.
So I guess there must be a mistake in the
configuration. But I really do not know where to look

The ActionForm is also used to display data on the JSP, so the method that

go
to a page, make sure that request is to an action and not directly to a
jsp.
As Andrew mentioned he has done, I have also moved from using separate

The only time I go outside the ActionForm is when I need to display a list

RE: Validator JavaScript displaying? Mozilla bug?
Brad, I am using Mozilla 0.7 and I saw what you described the first time I went to your page. I can't get it to repeat however. Then I tried for kicks on another machine and didn't see it at all. On that other machine I am just getting validator set up on a project and I tried it, and it looked fine each time in Mozilla. I did notice that I put the tags for the javascript outside the tags but inside the tags,whereas your are in the middle of the page. Maybe the first time it loads, since it hasn't loaded the entire page, it gets confused and displays the javascript but on subsequent loads, it is probably coming from cache and has the entire html and so renders it correctly? A little far-fetched maybe. I would try moving your javascript tag outside of the tags and see what kind of result you get. -Rob Rob Nocera www.neosllc.com -Original Message- From: Brad Plies [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 14, 2004 10:32 AM To: [EMAIL PROTECTED] Subject: Validator JavaScript displaying?

If you File->Save a garbled page, and load it from file, it renders correctly. IE does not have this problem, and I cannot find any evidence that any one else has ever experienced this either. What makes our pages a special case? I know all the affected browsers are related in some way, do they share some sort of common bug (In Gecko I presume)? Can anyone confirm they see what I see?

RE: sharing actions with superuser
Dan,
I would base the decision on how similar the actions are.
Some possible choices are:
1. Use the same action with the same method as you describe.
2. Use the same action but define two different methods within the action
based on what the user's role is. This way you can include private methods
which can be common to both roles.
3. Same as 2, except define a base action class and have two different
actions share that base class and define common methods in the base class.
4. As you mention, completely separate actions, forms, and jsps.
I have used all of the above depending on the situation. For example, in
one case, 6 different reports were being called, but all used the same
external call to run the reports and all shared 3 of the same lookup keys.
In this case I had a base report action class which defined all the common
methods and built additional report action classes for each report. Then
when a report was added, I just created a new action based on my report base
and added whatever else I needed in the new class.
As far as the JSPs are concerned, if I find more than a couple if statements
in my JSP, I would make two separate pages instead. I find it's easier to
maintain that way even though in some cases you will be making the same
changes in two different files.
In your case, I would suggest option 2 and possibly even the same JSP
page(s) if you could code it so the logic is all in the action.
Just my 2 cents,

Subject: sharing actions with superuser
This seems to be a common design problem, so I figured i would take
it to the struts list for advice. In my application, a user can
login and perform functions, such as viewing/altering one's own
profile. Additionally, a user can have "superuser" priviledged, in
which case they can alter other user's profiles. Would it be better
to split this into two actions or try to merge it in as a single
action? If I did it as a single action, there would be a lot of
if (request.isUserInRole('ADMIN'))
{
contact =
contactFacade.getContact(request.getParameter('user'));
}
else
{
contact = contactFacade.getContact(request.getRemoteUser());
}
within the action. Additionally, different messages would be
needed, different forwards would be targeted and the views would be
different because they may need different messages, different return
pages, etc.
In short, it seems like I am performing the same action, but
in many ways it is more different than the same. I sure which there
was a nice example of a "superuser" like interface that was
effecient. Anyone have any thoughts or followup questions?

RE: AW: struts get and set methods in formbeans
Jose, Jim is correct, your getters and setters correspond to what is in your JSP according to the Java Bean specification. The private variable name can be whatever you want, but generally to make things maintainable and easy to understand the variable names and getter/setter names are related. One implementation that I've seen is something like a private variable called "_test" and getTest, setTest as getter/setter names, and it works fine.

RE: Pass parameters between Action classes
A JSP is a servlet so the "request" in your JSP is the same as the
"request" passed to your Action from the ActionServlet. Maybe your
forward has redirect set to "true"? If it does, the browser is making a
new request and so anything you added with request.setAttribute will be
lost.

If the session times out or is invalidated, you will no longer be able
to access the same session using request.getSession(). Any session you
do access will be a new instance. This means that any objects in the
session are probably not accessible to your application any longer.
You can implement HttpSessionBindingListener on a bean that you store in
session and then implement the valueUnbound method to do something when
your bean is removed from the session.
This worked for me in Tomcat and let me know when a session was being
timed out, but I found that other application servers, such as
SilverStream, do not behave the same way. The session times out, but the
beans are not unbound and so the method is never called. From the spec
I don't think invalidating a session requires beans to be unbound if it
does, I think it is a bug in SilverStream's implementation.

Hi Folks:
Don't really know much yet about this...I've implemented
sensitive-form
resubmissions by way of tokens within actions but have a question about
when a session times out...
Under Apache (I don't know where yet), I suspect there's a
timer/variable
in some configuration file that says how long a session bean is valid
without any hits before it times out.I also think one can call
explicity "request.getSession().invalidate()" which does the same thing
but
affects all session beans
So here's my question(s):
- Anyone have any advice on how to deal with this programatically?
- When session beans do "timeout" or become "invalid", are they
automatically cleaned up by the system?So in essance if I have a
bean
called "fooBean" that I added via (request.getSession().setAttribute
("fooBean", fooBeanInstance) AND if the session automatically times
out
(without me calling request.getSession().removeAttribute("fooBean")),
does
the tomcat contain remove "fooBean" from the session scope or will it
still
be there if I call "request.getSession().setAttribute("fooBean")"
I'd like to understand a little bit more on how best to handle/deal with
situations where the session becomes invalid() or times out. What
happens
to all the beans/data contained for that session.With struts, do all
formbeans with session scope become defunct?

I agree there isn't a great deal in the archive. My situation sounds somewhat similar to yours in that I have a two-framed page. The upper page has a search form whilst the lower should, when the search is submitted show either the results of the search or errors if the form is filled out incorrectly. The way we're running things at the moment is to have a main.jsp containing a frameset with the two (search and results) jsps within the frameset. Within the tag on the search frame I have target="_top". In the struts-config file, the action mapping for the search page has an action forward back to the main page. So, the flow is that when a user submits the form, the form is validated, results are read from the database into a results object and we then get forwarded back to the main.jsp, leading to the redrawing of the two frames. To enable this to work we've had to define the search form bean and results object in session scope. I also had to write a new tag to read errors from the session rather than from the request and store form validation errors within the session rather than the normal struts way of sticking them in the request. Then, logic within the results.jsp when rendering the page first checks if there are any errors on the session and renders them to the screen if there are. If there are no errors it looks for a results object on the session and draws that. If there are neither of those (as would be expected on the first entry into the page) then the user just sees a blank screen. This method is working at present but it is leading to a great deal of redrawing. We're using Mozilla as the browser. It's worth noting that if you're using Netscape then you can set the target frame within your code in the Action class, avoiding forwarding back to the main.jsp page and redrawing everything. This doesn't work with either IE or Mozilla though.

RE: Found Solution to setting server side parm in Javascript BUT....
Theron,
There isn't an easier way because a FormBean is a server-side object.
You might think that your html page has access to it, but it's only
because of the sleight of hand involved in JSP programming. Since a JSP
is actually a servlet, it is only sending HTML to a browser so your
browser knows nothing of these objects.

Subject: Found Solution to setting server side parm in Javascript
BUT
After spending 2 hours trying to find a solution to this, I found one by
trial and error...
BUT THERE HAS GOT TO BE A BETTER WAY :-)
Here's what I did but I can't believe it's "this" difficult to do...
Here's my checkfield property that needs to "force a form value to be
updated":
Here's the javascript function:
function setCurrProductType(inProductType) {
alert("Setting curr product type to: " + inProductType);
window.location="SetProperty.jsp?enteredPt="+inProductType;
}
and here's the SetProperty.jsp
-
<%@ taglib uri="/struts-bean" prefix="bean" %>
<%
//
// If they changed the product type on the first page, set it
// here in the form object...
//
String sCurrProductType=request.getParameter("enteredPt");
psInfo.setCurrProductType(sCurrProductType);
System.out.println("Current Product Type = " +
psInfo.getCurrProductType()
+ " current page = " + psInfo.getCurrpage());
psForm.setPsdProductType(psInfo.getCurrProductType());
%>
So in essence, the "forward" tag simply causes control to come back to
the
page I was on... But in-between, I was able to set a form bean
propertyAgain my problem is the form bean property is not
updated
until you hit the submit button... In this case, I don't want a submit
to
occur when you change the contents of the dropdown. Only the property
for
that drop down should change... After adding this, when I click to go
to
the 4th tab, the action now sees the newly changed value
It works BUT I have to believe there's a better way!!!I open to any
suggestions...

Hi Folks:
I'm doing a mimic-JTabbedPane approach. I have a screen with 5 tabs.
I
am using 1 form object and 5 action mappings...
On tab 4, I'd like to detect changes made to a field on tab 1. I
notice
I can change the field on tab 1 but tab 4 does not know about until the
form is submitted.I can't submit the form...
I'd like to have a Javascript handler that implements the onchange() and
somehow sets a session attribute or some kind of trigger that tells tab
4
to "reload" itself when this field on tab 1 has changed.I notice if
I
change these values, the form object will not get the new values until
you
hit submit.Having the javascript function call submit is not an
option
either... Any ideas on how best to do this??
If I could access my form-bean directly within the Javascript method,
that
would be an option to (as I could call the set method on the form
object)
but I am not sure if the javascript can access the form object directly
and
call a set method?

You can use redirect="false" to make it a forward, which is what you

RE: null value for a nested property
David,
I find it's best to use a form bean that is different from your data
object, so that your get methods on your form object can return an empty
string if null instead of actually returning a null value.

Subject: null value for a nested property
I currently am using an tag on a form to display the name of
a
state. The tags looks like:
The problem is that ocassionally the state field on the address bean is
null. When this occurs the PropertyUtils.getNestedProperty() method
throws
an IllegalArgumentException which causes my jsp to break. To circumvent
this problem I have written my own tag that extends BaseFieldTag and
overrides the doStartTag() method. I basically perform the same
functions
as the BaseFieldTag.doStartTag() method, except that instead of the
following call:
Object value = RequestUtils.lookup(pageContext, name, property,
null);
to get the value I catch the IllegalArgumentException and set the return
value to an empty string:
try{
valueObject = RequestUtils.lookup(pageContext, name,
property, null);
}catch(IllegalArgumentException e){
//This exception indicates that one of the nested properties
returned null
//we want to set the value to null and not throw the
exception
out
//to the jsp
valueObject = "";
}
I am wondering if there is a better way of dealing with this problem. I
don't like the solution I am using, but I can't think of anything else.
How
about adding an attribute to the form tags that specify how null
property
values should be handled?
Thanks for your help,
Dave

RE: ActionForward question
Your best bet is to set up an intermediate page that uses Javascript to
do automatic refreshes.
There were a couple other suggestions on this list a little while ago.
One was to set up a page that lists the transactions in progress and
their status and have the user refresh the page themselves.
You can't use http to push stuff out to a browser, only respond to
requests, and once you respond, you're stuck waiting for the user to
make another request.

Hi,
Is it possible to send pages to a browser depending on the processing

of an action? Lets say you have to process a long operation in the
background such as a credit card validation or the like, is it possible
to
show the user an intermediate page telling him that some work is in
progress
and then show the result page when it is generated?
In the Action class it looks like this:
// test if session is valid
af = super.validateForm(form, mapping, request);
if (af != null) return af;
// test if a form has already been delivered
if ((ContainerName == null) || (ContainerName.length() < 1))
//show
form
{
saveToken(request);
return (new
ActionForward("/Templates/Forms/ShowEnumNTGGForm.vm"));
}
if (this.isTokenValid(request))
{
resetToken(request);

// START PROCESSING HERE THIS COULD LAST 30 SECONDS OR
MORE

RE: iterate tag to repeat for a collection of individula objects
In your iterate tag, name should be the name of the form bean, and property should be the name of the form variable that contains the list. You also probably need the type attribute to specify what type of objects the list contains. In the code you provided it's looking for a form bean called "clientList" that contains a collection called "clients".

RE: Design question about ActionForm's validate method
Direct the user to an action that isn't the action associated with the page in question, even if all that action does is forward to the JSP page. Generally the action's associated with a JSP page get called from that JSP page. ActionA forwards to B.JSP, B.JSP submits to ActionB and so on... Alternately provide a hidden form variable in your page, in your validation method, check for it, if it's not there, don't continue validating as the user did not just submit the page.

The ActionForm's validate method can be configured to verify form data from a page and generate error messages which may then be displayed on the page for the user to see. This works fine when the user has accessed the page by specifying a JSP file in the URL. When the user accesses the page by calling the Action directly though, the validate method is called before the user ever sees the page, much less inputs valid data to the form. This leads to an unfortunate display of unwarranted error messages. It would be nice if the documentation would provide a rule such as: If one plans on the user calling the Action directly in the URL then one should not use the automatic validation provided by ActionForm. Further, as having two different procedures to generate a page can lead to subtle errors, one should decide whether a page will be accessed as a JSP or as an Action and design for the one scenario. The simplest (and safest) design rule will be to access all pages through either one mechanism or the other. Comments?

RE: redirect vs forward
A redirect tells the browser to load a new page whereas a forward sends the current request on to a new action or page. The big difference is that in a redirect the browser is making a *new* request, in a forward, the current request is carried on to wherever with all the attributes of the original request. Another consideration is that when a redirect is done, the client now knows where they were redirected to, whereas multiple forwards can be performed and the client only knows about the original request that was made.

Robert,
Thanks for your response. Actually the way that I currently have it
coded is the way that you have described. I created a
getDisplayValue(),
but this just doesn't seem right to me. My understanding about the MVC
architecture should allow for your display to not have to be tied to
your
model. If my formBean is the one responsible for returning the data
type
for my model, then I am violating this principal. Maybe it is a minor
detail, but that was the first thought that came to my mind.
