Where to build dropdown lists?
Sorry if this is a stupid question, but any help is much appreciated! I have some drop down lists that I populate in my action class, which means I call myPage.do each time. This was working nicely, until I tried adding some validation. If this fails the action class is not called and then when the page tries to find the bean containing the list for the drop down it does not exist! Previously we built the lists in the reset function in the form class, but I was wanting to move all the code out of here with the idea of using the dyna forms.

Re: Iterating the resultset contents in the view (jsp)
Well, okay, that makes the discussion a bit more abstract ;-). I understand your
point, but the bottom line is that it's just a namespace (package) and an
external library (JAR file). To my mind, the real question with either Result or
RowSetDynaClass is how far from the data layer do you want the column names to
propagate? In some cases that may be all the way to the view layer.

and a utility class javax.servlet.jsp.jstl.sql.ResultSupport:
public class ResultSupport {
public static Result toResult(ResultSet rs);
public static Result toResult(ResultSet rs, int maxRows);

to accomplish something similar. The SortedMap instances returned from
Result.getRows are keyed by the ResultSet's column names and use the
Comparator String.CASE_INSENSITIVE_ORDER so that you don't have to
worry
about matching the case of the column name exactly. So, depending on
what your preference is, you can just do:
ResultSet rs = ...;
Result result = ResultSupport.toResult(rs);
request.setAttribute(MyConstants.RESULT, result);
or:
ResultSet rs = ...;
Result result = ResultSupport.toResult(rs);
Map[] rows = result.getRows();

A fairly standard approach is to create a class that represents a row
of
your ResultSet and store a List of those objects in the request for
the
page to iterate over.
If you don't want to create a class for each result, you should check
out
the BeanUtils DynaBeans. This little gem:
http://jakarta.apache.org/commons/beanutils/api/org/apache/commons/beanutils/RowSetDynaClass.html
allows you to transer ResultSet data to DynaBeans in a trivial amount
of
code.
David
If so, how would you iterate over each array in the collection with
the
logic:iterate taglib? All of the examples only show iterations over
single
column lists.
Any help would be appreciated.

Re: two little questions
I would think that Q2 basically depends on which database you're using. You should be able to find out what character encoding your database supports by reading the documentation for the field type you're using (eg varchar). To complete the answer to your first question with a why, yes, you should filter out html, unless you know that all the users can be trusted 100% (and you know that you're not storing any sensitive information in cookies). In the olden days, Easyboards allowed html and, incidentally, javascript, AND stored the username and password in a cookie. It was a simple matter to write a script that called an image on my server with, as arguments, the cookie values (don't worry, I only did it as a proof of concept and filtered out the middle characters of all the passwords before posting it up! :-P). If all you store in the cookie is the session ID, you're probably safe from that type of attack. However, there's other annoying things people can do such as break the layout of your forum. A good solution for an untrusted forum (eg not the internal company forum) would be to turn all the and into lt; and gt; as suggested, and then to provide the alternative of using UBB-like tags, eg [b]..[/b] for bold, etc. You can pick these out with regular expressions yourself, or if you find them there are probably already libraries out there somewhere that will do this for you. -- If education is too expensive, try ignorance. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Where to build dropdown lists?
My solution, which is perhaps not the most efficient memory-wise, is to simply put it in (and retrieve it from) the session rather than the request. Then when I do go through the populating action, if this is a list that is liable to change often I reload it from the database. If it is a fairly static list I just check if it's already there and do nothing if it is. I guess an even better solution (for a general-usage list) would be to put it in the application-wide context, so you load it once for all users (if it's really very static). That solves the memory usage issue, and even if it's non-static you can work around the problem by making sure that you reload the list application-wide whenever it is changed. -- If education is too expensive, try ignorance. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: FW: need help
It all depends on how much maintenance you expect this project will require once you're finished. If it's a fire-and-forget, any shortcuts will do so long as you finish the project on time. If you're going to have to maintain this, you want to do it properly. With this in mind, actions should be 'dumb' things that just call your Manager classes to actually do the work. With this, you end up with tons and tons of actions, but the good aspect is that they're all trivially simple and should be extremely bug-free. This way you can concentrate on the manager and DAO classes for bug-writing-and-finding... So the idea is to have as many forms as required (each with its own form-bean and potentially two associated actions - one to populate the form options/selects/radio buttons/etc, one to retrieve the results and update the database), without trying to consolidate things that look the same into, say, a single action with a couple of if/thens. Don't go into a mode of thinking where you're trying to save on how many actions there are - why do you want to do the work of 2 actions with one?? If you are repeating any non-trivial code in your actions it's a fair bet that you have code in there that shouldn't be there. Doing it this 'right' way will force you to produce large quantities of trivial code but that's the good thing - it's all trivial, it's all easily maintainable, it's all easy to change, it's all very clear to any struts programmer. I suggest getting a good book such as Ted Husted's Struts in Action to get the basics right before you get onto this project by the way, otherwise you'll have no end of trouble. To your question about tiles, yes, tiles is excellent and personally I see no reason *not* to use it in every web-based project. -- If education is too expensive, try ignorance.

Re: FW: need help
The question is whether you have the time to familiarise yourself with struts in order to take advantage of its time-saving features. Tiles would be good, having an action class for each object would be sensible, with different action mappings for display, create, update, delete and other operations. However you may find that rushing everything will cause real delays if you are using struts and you are not sure how to solve problems in areas that you have not learnt.

I designed a system where I can specify in my action which dropdown lists I require with a method call.

Search of the archives if you insist on using Request scope for the form lists and you'll find ways to do it, but none of them seemed worth the hassle(imo).

Oops, spoke too soon.
You discussed 2 options:
1) All drop-down list data goes into session

instead of edit JSP
I went with #2 and that brings up a new issue. Doing that causes all of
the current values for the fields to be lost (i.e. the user inputs a bad
number format in a field they click submit and receive the JSP with
a list of errors at the top) Because the process went through the edit
action again, the Action re-queried the database and updated the
ActionForm with database values, overwriting all the user's values
(including ones that were correctly edited and contained no errors).
To avoid this I have to insert code in the edit Action to check for a
populated ActionForm before querying the database. This feels a little
messy.
Of course I could use the session solution (#1), but I like to avoid
using sessions unless absolutely necessary. In addition, these drop
downs could have 100's of items in them, I'd like to keep big chunks of
data like that in the request.
So the alternative, I guess, is to have another action that NEVER
queries the database, but just prepares a blank form. I actually already
have one of these... it's my create action.
Aaron, this sounds like a good idea if it works for you. You can also
manually validate in your save action (the action your form submits to)
by doing something like:
// Validate form parameters ...
ActionErrors errors = yourForm.validate(mapping, request);
if (errors != null !errors.isEmpty()) {
saveErrors(request, errors);
//do whatever you need to do to put your
//drop-down list values back into the request.
return new ActionForward(mapping.getInput());
}// end validate
And set validate=false in your edit action mapping.
Susan Bradeen
This appears to be the best practice in this situation anyone else
have any feedback?
Thanks again,
Aaron

You have at least 2 choices.
1) You can put your drop-down values into session scope.
2) You can set the input attribute of your action mapping to your edit

Re: Where to build dropdown lists?
When using the client side validation, there is always a javascript pop up box that says something along the lines of 'Your a thick b*stard, fill in xxx!' Our client requirement is that we produce a list of errors at the top of the page, (the red UL kinda thing), which rules out the use of these java script pop ups. Another thing that I noticed when playing with the JavaScript pop ups was that all the validator JavaScript, whether used or not is included in the JSP code. I ende up with hundreds of lines of JavaScript, including date, email and phone number validation, for a login for that had two elements? Is this the way it should work?

RE: [ARTICLE] Succeeding with Struts Pt 2: Indexed Properties of Beans
Rick, I haven't found a good way to do this without a lot of gross %= hacking, specifically because the Struts and JSTL interators give you a handle to the index of the interated object, not the key. But frankly, I don't see a huge need to do this.

Re: Where to build dropdown lists?
Susan Bradeen wrote: I also use a method call to retrieve my dropdown lists, but I gave up using an action as the input mapping parameter. I didn't see how I could implement it without putting a returning from validation check in there somewhere, and those particular setup actions have become complex enough already. I resorted to calling validate() manually in the save actions. Good or bad, it works well for my application. I set up an action mapping called failedValidate and gave it a parameter finished - this would set an action token variable in the app's action base class. I programmed it so the action token is always one of display / insert / update / delete / other / finished. In the case of finished, nothing happens. In all cases though, the base class makes sure the dropdown collection is there. Since it's in my action base class, I never have to worry about programming it manually. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: radio button issue
I went to the similar situations before. Tabbing to focus needs some understanding of UI design technology. The IE browser treats a group of radio buttons (with an identical name) as one logical unit on a page. So the tabbing can only give you the focus to one of the radio buttons. If you would like to give another try, you will find the IE browser treats a select menu (with one visible row) as one logical unit on the page too. Once you tab to focus it, you use the up and down arrow buttons to make selections. If your business requirements need browsers, I would say it is better to follow the *default* behaviors of the browsers.

Re: FW: need help
Hi Mohan You can have one action form and one action class for different JSP pages.But it would be a good design if all the JSP pages represent one type of function in your application. A typical example would be a Registration Module. Registration requires say around 2-3 JSP pages one after the other. In this case you can have action form say RegistrationForm.java and one Action class called RegistrationAction.java. You can do the following in the struts-config.xml for such form-bean name=registrationForm type=somepackage.webapp.RegistrationForm for the form-bean declaration and action path=/action/register type=somepackage.webapp.RegistrationAction name=registrationForm scope=session validate=false forward name=input1 path=/forms/some1.jsp/ forward name=input2 path=/forms/some2.jsp/ forward name=success path=/forms/some3.jsp/ /action for the action mappings part. You can have conditions in the Action class to take you to the respective jsp page upon validation of each page. -Good luck Mohan Hi, I am new to Struts and I have to complete a project with an aggressive deadline. I want to know the following: My application will have about 80-100 screens each having different action items. Most screens will have a common header, footer, and a navbar. My questions are: I thought of using Tiles for my application. Is that a good idea. -Should I have to have one action form for each screen or can I group the screens and have one action form for a group of screens. Which would be a preferred method? -Should I have to have one action class for each screen or can I group the action classes the same way as forms? Which would be a preferred method? -Every screen of mine is going to be a jsp page. I want to populate the form data at the time when someone enters the page from another page and I want to write the data into the database at the time when the user leaves a page with an action. Is this possible in the same action class? How does the flow work? Does the control go to the action class first before the form data is picked up for display. If that is the case, will there be an easy way for me to set the form data from the same action class for the form before the data is displayed? Where can I see a sample code if I use one single action class for loading the data and for processing the actions within the form? What should be the setting within the struts-config file for the above scenario. Sorry, if my questions are dumb. I need help.

Re: URL validation with struts???
You could definitely do that, too. If you just create a new Url(yourstringhere) it will raise that exception if it's malformed, so it won't waste time creating a connection to a malformed url. I guess that's probably a better solution than the regex one, too, because it's simpler. -- If education is too expensive, try ignorance.

URL changed by user - how to restrict?
Hi, I am developing a web application in which some parameters are passed through query string. I do not want to allow users to manipulate the query string. If they manipulate, they should be logged off and taken to login page. For ex.., I have a page http://mymachine:8080/appln/test.jsp?user=1004 In this page, user details are displayed. If a user changes the query string - from user=1004 to user=1005 - and clicks ENTER, then the details of 1005 are being displayed. I want to avoid this. In such cases, user should be logged off and taken to login screen. How can this be done using Struts? Any clue? I believe this can be done by checking HTTP_REFERER, but I'm unable to get it right.

Re: URL changed by user - how to restrict?
From what you've described, you don't need to pass any user number or id. With the internet, being the stateless beast that it is, how will your application know that any particular request is or isn't supposed to access some particular user number? I think you are going about this the wrong way.

You should have access to the Form generated from the request from the
client and check the form properties, and your code could contain some
functions, like dontSatisfyValidation, for verifiy that each field
concerned by the page which is actually checked.
For automatic validation, driven by rules defined in
validator-config.xml (or validator-rules, check the 2 files), (i think
you think to this when you say what is the method call I use to
validate just a single field) you do : super.validate() on the
beginning of your form. (which must extend ValidatorForm, check the
Javadoc for this class).
So good luck, re-read the doc and the examples if you don't understand

Re: URL changed by user - how to restrict?
I agree with what the others said. You can never, and should never, trust anything that the user can change. And you should certainly not be storing the logged in user's id in the query string. I think you may need to read a bit about basic http security. A framework like Struts requires you to actually know what you are doing when it comes to basic web design techniques. It does not give you some sort of 'magic key' that allows you to skip over all that stuff and start writing web applications right away - if you do, they will be riddled with holes. Btw, there is no way you can do what you're asking. HTTP_REFERER can be altered by the user too. -- If education is too expensive, try ignorance.

Re: Populating Drop downs
Qasim, I actually use separate actions. I have an edit action, an update action (which handles both creation of a new record and updating of an existing record) and a list action (which views data about certain records): !-- BAND LIST -- action path=/band/list type=dove.struts.actions.BandAction parameter=list validate=false /action !-- BAND CREATE -- action path=/band/create type=dove.struts.actions.BandAction name=BandForm scope=request parameter=create validate=false input=/WEB-INF/jsp/html/band/edit.jsp /action !-- BAND EDIT -- action path=/band/edit type=dove.struts.actions.BandAction name=BandForm scope=request parameter=edit validate=false input=/WEB-INF/jsp/html/band/edit.jsp /action !-- BAND UPDATE -- action path=/band/update type=dove.struts.actions.BandAction name=BandForm scope=request parameter=update validate=true input=/band/create.action /action You'll see I have different actions fronting the same JSP. In addition I use a practice of hiding the JSPs behind the WEB-INF directory. The spec indicates that these directories must be secure so nobody can go to a JSP without visitng the action first. A second strategy I use is to build only one action for each of my sub actions (see the type=) are all identical. To differentiate which mode the action is in I assign a different parameter attribute for each. Then within my execute method I check the parameter value: String param = mapping.getParameter(); and then route to a private method inside the Action class. This keeps all the code in one place (in this case, in the BandAction class). Qasim Khawaja wrote: How do you distinguish the when the execute method is being called to populate the form and when it is being called to post the data from the form?

Re: Text tag size
Using the size attribute to control the field width of a text input is not recommended. In our demos at http://www.netspread.com, we use style=width: 100pt; for many input fields. Note that the pt is one of absolute units used by browsers. It gives you the ability to control the screen layouts regardless what resolutions and what fonts the end users are using. So our demos works on screens with resolution 1600x1200 and 1024x768 and with different font settings.

RE: Use of Validator in a Wizard Validator
Yes but...
It's my understanding that super.validate()
validates all the form's fields at once. In the case of a
wizard you don't have all the fields populated
by the user until they reach the last page.
I'd like to take advantage of the rules in
validation.xml and not (re)write the code inside
the braces.

RE: Indexed form values
Sandeep,
Thank you for your response. I checked in mail archive and found several
suggestions. In particular I looked at this suggestion
http://www.mail-archive.com/[EMAIL PROTECTED]/msg72404.html
and realized that there is a slight problem with this code. For those who
would like to know how I got it working here it is:
Change the Code which says :
// THIS METHOD IS REQUIRED IF YOUR FORM IS OF REQUEST SCOPE.
public MyBean getIndexedBeans(int index) {
while (this.myBeans.size() index)
this.myBeans.add(new MyBean());
return (MyBean) this.myBeans.get(index);
}
To this:
// THIS METHOD IS REQUIRED IF YOUR FORM IS OF REQUEST SCOPE.
public MyBean getIndexedBeans(int index) {
while ((this.myBeans.size()-1) index)
this.myBeans.add(new MyBean());
return (MyBean) this.myBeans.get(index);
}
because size is not zero-based where as index is.

tlds not found compiling in Netbeans

A dynamic _map_ (not list) index?
I was looking at http://jakarta.apache.org/struts/faqs/indexedprops.html, and realized it's possible to get a dynamic arraylist index by using Struts-EL. Well, my question is, if I have a radio button like: logic:iterate id=element html:radio property='userSkill' value=value(somekey)/ /logic:iterate Can I _still_ use Struts-EL inside the value= attribute to generate a dynamic key based off some exposed iterator (e.g. element from above), which is indeed a String value? What's a way to do this? It isn't quite the same as an index for a list, it's not a number, and there's no concrete example for a dynamic map index, which is why I ask. Can someone clue me in? I'm sort of stuck :). Thank you. Martin - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: How do you access an application.properties value directly fromwithin a class?
Hi Mark,
This bit of code should help (from Ted Husted's book! ;-) )
Locale locale = (Locale) session.getAttribute(Action.LOCALE_KEY);
MessageResources messages = servlet.getResources();
String message = messages.getMessage(locale, important.message);
And if there are replacements ({0}..), eg:
String message = messages.getMessage(locale, important.message, new Date());

reusing same form for inserts and updates
I've searched the archives for this type of discussion but I'm not really finding what I want. I'd like to reuse the same jsp form for both inserts and updates of a particular set of data. My current solution is to come into the action with a flag of new or edit. If edit, the action will fetch the existing data into the FormBean by the primary key (int) which is currently in the FormBean, then forward to the input view. If new, the action will just forward to the input view (thus the primary key is 0) The input view is the jsp form, which has a hidden property set to the primary key of the FormBean. The form is then submitted back to this action with a flag of save, and then it will check for the presence of the primary key (from the hidden field), and do an insert or update based on whether or not it is 0. Another variation of this is to set a specific field in the FormBean instead of the primary key, but it is the same idea (still requires handling this field as a hidden field in the form) Which I found at: http://www.reumann.net/do/struts/lessons I'd really like to clean this up a bit, hopefully by removing the requirement of setting a hidden property in the form. One idea was to put the new/edit information into the session, but this fails if the user has 2 browser windows open, trying to do a new record in one window and an update in another (since they share the session). Another idea was to attempt an update, and then fail back to an insert, or vice versa. But that is an extra db hit. Any suggestions or experiences would be helpful.

Is this really the best way to handle this problem
I've been struggling with a problem similar to the one described (and solved) at http://www.mail-archive.com/[EMAIL PROTECTED]/msg50901.html . Is this really the recommended way to solve population / repopulation of properties stored in a List() of whatever-data-object-i-need-in-the-form-of-a-bean ? Is there a better way to acheive the same result ? (I.e represent a collection in a form) I've read that a practice often used to represent collections (a DB-table for intstance) is to make a bean that has getters / setters for the properties of a single row and then have the ActionForm contain a List() of those beans. One for every row (in the DB-example). That far I can follow, and see how / why. But is there no better way to update the values in the ActionForm (beans) when the data is submitted than in the URL above ? //Linus Nikander - [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

In fact I do this myself. But the reality is it's still an identifier that's defined in the data layer, in this case embedded in SQL. Isn't that going to be true even if you bury SQL inside a DAO? Someone somewhere is going to have to deal with the column names that are defined in your database. My point was that I'd be more concerned with identifiers defined in the data layer getting referenced in the view layer then I would with using Result and ResultSupport outside of a web app. A lot of people externalize SQL command strings into properties files so that they can tweak them for differences between databases. This would also give you a level of separation, in that you can reference the actual column names ONLY in the properties file strigns, and have your code using the result set deal only with the aliases set with as. I've found this approach to be quite useful. It gets tough when you need to dynamically create a query based on a user's search form values. In that situation I define each SQL search chunk under it's own key and use MessageFormat to insert values appropriately.

RE: reusing same form for inserts and updates
My primary keys are the email addresses of the users, and I always bring up a blank form and allow the user to choose (radio buttons) to retrieve, update, or submit new records based on date. The userId is stored in session scope at login. Mark -Original Message- From: Wes Rood [mailto:[EMAIL PROTECTED] Sent: Tuesday, July 15, 2003 1:13 PM To: Struts Users Mailing List Subject: reusing same form for inserts and updates I've searched the archives for this type of discussion but I'm not really finding what I want. I'd like to reuse the same jsp form for both inserts and updates of a particular set of data. My current solution is to come into the action with a flag of new or edit. If edit, the action will fetch the existing data into the FormBean by the primary key (int) which is currently in the FormBean, then forward to the input view. If new, the action will just forward to the input view (thus the primary key is 0) The input view is the jsp form, which has a hidden property set to the primary key of the FormBean. The form is then submitted back to this action with a flag of save, and then it will check for the presence of the primary key (from the hidden field), and do an insert or update based on whether or not it is 0. Another variation of this is to set a specific field in the FormBean instead of the primary key, but it is the same idea (still requires handling this field as a hidden field in the form) Which I found at: http://www.reumann.net/do/struts/lessons I'd really like to clean this up a bit, hopefully by removing the requirement of setting a hidden property in the form. One idea was to put the new/edit information into the session, but this fails if the user has 2 browser windows open, trying to do a new record in one window and an update in another (since they share the session). Another idea was to attempt an update, and then fail back to an insert, or vice versa. But that is an extra db hit. Any suggestions or experiences would be helpful.

mapping.findForward( mapping.getInput() ) ?
In Cavaness's book Programming Jakarta Struts, there is a code sample on page 188 that contains a line I don't understand. In the execute method of an implementation of an Action class, is the following line of code: return mapping.findForward( mapping.getInput() ); Doesn't the input have to be an Action? The DTD says action or other resource. What other resource? Could I put the name of a tile in there? I tried putting the name of a forward in there, but the validation framework complained that it didn't start with a /.

RE: [ARTICLE] Succeeding with Struts Pt 2: Indexed Properties of Beans
From: Craig R. McClanahan [mailto:[EMAIL PROTECTED] The iterated object has key and value properties to give you access to either the key or the value with a nested expression. Right, but there's no way to use them with the indexed=true flag of the html tags. You still end up having to do some convoluted field name generation using EL or %=.

Re: Is this really the best way to handle this problem
I've seen two ways of dealing w/ this problem, both of which I see as 'hackish'
in nature.
Solution A:
In your getters/setters you implement the following code
public MyCustomBean getMyCustomBean(int index) {
while(index = myCustomBeanList.size()) {
myCustomBeanList.add(new MyCustomBean());
}
return (MyCustomBean)myCustomBeanList.get(index);
}
In that way you'll never encounter the common IndexOutOfBoundsException. The
problem here is that you tend to use alot of hidden fields in your UI to repopulate
the data back into the dynamically created beans.
Solution B:
In your reset() method you repopulate your internal Collection of beans. The
problem w/ this approach is that often times you have a separate Action that
prepopulates your ActionForm. This provides for good separation - the Action
is a retriever of a data (nothing more) and the ActionForm is merely a container
for data (nothing more). With this approach your ActionForm suddenly starts
becoming more intelligent than it really should be. Now it's aware of how to
populate itself...not a good thing IMO.
I'd be very interested in hearing other solutions to this problem as I find
both of the above solutions cumbersome and hackish and would love to stop implementing
them.
I've been struggling with a problem similar to the one described (and
solved) at
http://www.mail-archive.com/[EMAIL PROTECTED]/msg50901.html .
Is this really the recommended way to solve population / repopulation of
properties stored in a List() of
whatever-data-object-i-need-in-the-form-of-a-bean ? Is there a better way to
acheive the same result ? (I.e represent a collection in a form)
I've read that a practice often used to represent collections (a DB-table
for intstance) is to make a bean that has getters / setters for the
properties of a single row and then have the ActionForm contain a List() of
those beans. One for every row (in the DB-example). That far I can follow,
and see how / why. But is there no better way to update the values in the
ActionForm (beans) when the data is submitted than in the URL above ?

Re: A dynamic _map_ (not list) index?
Never mind this question, I answered it to myself. The EL works just as well on map backed forms as it does on list-backed forms, or list backed form properties, more correctly :).
