duplicate form object
im new, i have 2 subscriptionForm objects instead of a single OID. The trace below involves these activities: 1. subscription.jsp is submitted and handled by subscriptionForm whose configuration includes: name=subscriptionForm scope=session 2. a forward occurs on name success and the config codes for the action actionpath=/saveSubscription to forward to path=/Welcome.do/ 3. the forward action for path=/Welcome has attribute name=subscriptionForm and attribute parameter=/Welcome.jsp The Problem - There should only be 1 subscription object but there are 2 different ones : - one at step 1 - another one at step 3 Why the duplication?

RE: NoClassDefFoundError in custom validator
Ok I figured out a way to make it all work ...
The solution ended up being to put all the commons jar files in the root of
the ear, and add them to application.xml as java modules. Looks like it was
indeed a classloader issue then ... which would lead me to think that this
is a bug. No reason why Struts shouldn't be able to do all of the
reflection, especially since this is hardly pushing the envelope. Any
thoughts?

I JUST made it work though with a simple update of the commons source code.
I guess I could look into submitting my update if they / anyone is

I changed the org.apache.commons.validator.ValidatorUtil.getValueAsString()
method from:
public static String getValueAsString(Object bean, String property) {
Object value = null;
try {
value = PropertyUtils.getProperty(bean, property);
} catch (Exception e) {
log.error(e.getMessage(), e);

to:
public static String getValueAsString(Object bean, String property) {
Object value = null;
try {

} catch (Exception e) {
log.error(e.getMessage(), e);
}
//Special case, check if String[]
try
{
String[] valueArray = (String[])value;
if(valueArray==null || valueArray.length==0)
{
value = null;
}
}
catch(ClassCastException cce)
{
//Then it wasn't a String[]
}
return (value != null ? value.toString() : null);
}
I guess, just to be safe the second catch could catch Exception.
Anyway, it fixed my validation problem for String[] and doesn't appear to
have broken and validations which worked before.

Subject: Re: Validator required not working with String[] multi-select
AFAIK, the standard required validator doesn't work with arrays. Or, if it
does, I wasted time writing a custom validator ;-). I'd be intersted to hear
if
anyone really has used the required validator successfully for an array
field.
I suppose I should check to see if there's a bug/RFE for an array validator
and
submit it...
Quoting Bailey, Shane C. [EMAIL PROTECTED]:
I sort of already sent this message to the list but I made a mistake
(didn't
proof read my message) so here it is again but corrected ...
Validator required validation is NOT working for my String[] (in a
dynaform. I have seen others on the list say it works for them.
Anyone else experiencing the same problem? Possibly it is because I am
using
a multi-select?
Basically, if nothing is selected then instead of null be sent back for
that
parameter I am getting a zero length String[]and it's toString() value is
[Ljava.lang.String;@3cfaab which is important because of the way the
validateRequired() method works...
I looked at the source code (of my commons-validator.jar using jad).
Maybe I am using an older version of the commons-validator jar and this
was
fixed or I am doing something else wrong?
If so, where is the latest commons-validator.jar?
Here is how my field is declared on the JSP:
html:select property=roles multiple=true size=7
html:options collection=%=my.Const.ROLE_TYPES%
property=roleName/
/html:select
Here is how it is declared in the struts config:
form-property name=roles type=java.lang.String[]/
Struts source Code:
public static boolean validateRequired(Object bean,
ValidatorAction va, Field
field,
ActionErrors errors,
HttpServletRequest request) {
String value = null;
if (isString(bean)) {
value = (String) bean;
} else {
value = ValidatorUtil.getValueAsString(bean,
field.getProperty());
}
if (GenericValidator.isBlankOrNull(value)) {
errors.add(field.getKey(),
Resources.getActionError(request, va, field));
return false;
} else {
return true;
}
}
Problem:
ValidatorUtil.getValueAsString(bean, field.getProperty()) does a
toString()
on the value and a toString() on a String[]
which isn't null it is some String like [Ljava.lang.String;@3cfaab and
so
then isBlankOrNull() is checking for null OR value.trim().length==0 and so
neither is true and so validation passes.

Re: AW: Show validation errors in a dialog
If you are talking about presenting the server side validation errors
on the client I believe you could do it on the
'onload' event handler in the BODY tag.
If you want the client side validation performed by Javascript
to display errors then look at the struts-validator
example.

Subject: RE: Can Validator javascript show more than one error at a time?
The generated Javascript groups tests by type (required, mask, min length
etc) and calls them as follows:
function validateRegistrationForm(form) {
if (bCancel)
return true;
else
return validateRequired(form)
validateMask(form)
validateMinLength(form)
validateMaxLength(form)
validateEmail(form);
}
Due to the way the expression is evaluated, if any test returns true
the
subsequent tests are not executed.
If you had several missing required fields then those errors would be
grouped together. But if you had only one missing required field and
another
type of error, you would not see the second error message until you
correct
the missing field error.
See the struts-validator sample application (shipped with Struts) for
examples.

Re: adding / creating new collection elements in a form
Hi Dan,
This seems to be the most promising solution as of yet. I am
however a little unclear as to how this avoids the need for
a request for each row added.
If I understand what your describing the LookupDispatchAction
extension is for handling forms with multiple buttons. As you
describe one of the operations of this action is to add a new
element to the collection from which I am populating the form
fields.
My confusion is that I don't see how a request is avoided for
every new row added. I would like to add multiple rows to my
html form on the client side w/ javascript (making no request
to the server) and then allow the user to populate and when
submitted all new rows result in new instances of whatever
kind of object being added to the collection.
I can provide a more detailed explanation if it helps, I'm not
entirely sure I can do what I want to do with struts at this
point.
Rob
Dan Tran wrote:
I just implemented myself, so let me throw a shot at this.
In my case, I make my action derived from LookupDispatchAction
which can handle multiple button submission handlers.
One of the button is called something like addRow. When you hit this
addRow button, struts will repopolate what ever on your screen and dispatch
it
to your addRow handler where you can add new empty row to your collection
and forward back to your screen.
regarding your out of index problem, I would suggest to use common
Collection
ListUtils.lazyList. Here is an example a lazy collection in a my form
private List gradeViews = ListUtils.lazyList(new ArrayList(), new
GenericFactory(org.glvnsjc.view.StudentGradeView));
//there is no direct setXXX, call getXXX first and populate the object
// lazy list takes care all dynamic allocation
public StudentGradeView getGradeView(int index) {return
(StudentGradeView) gradeViews.get(index); }
public void removeAllGradeView() { this.gradeViews.clear(); }
public List getGradeViews() { return this.gradeViews;}
Please look up GenericFactory in the maling list, I dont want to repost it
If you dont know LookupDispatchAction yet, learn it. It has the magic that
I cant live without
Good luck!!!

Subject: Re: adding / creating new collection elements in a form
Perhaps I was not making myself clear when I first posted this.
I know how to write the javascript, I know how to use struts
nested/logic tags. What I was looking for when I posted was
a solution whereby I could add new elements to a collection
in a form. Not update existing elements, thus increasing the
size of a collection based on properties from fields that
were added by client side scripting.
I've not been able to find a solution to this within the mailing
list. But I would like to the following.
I have a page with a collection of fields which are populated by
a form (via it's collection). I also have a button which would
allow the addition of a new row. (hopefully)
Name Descrip
[ xy ][ foo ]
[ ab ][ bar ]
Add
(1) I would like to have the add button add a new pair of text
input fields each time it is clicked. (2) I would like it if
clicking add did not make a request to the server this being the
case it suggests some kind of client side javascript adding the
new fields.
The problems of course with this are the following.
(1) client side code won't be able to utilise the struts tags
and as such I won't know what values to set the appropriate
input text element attributes to.
(2) It is highly likely that even if I solved problem (1) that
it would result in a IndexOutOfBounds exception, or just not
bother with the properties from the new fields.
Has anyone else solved this? Does struts have a mechanism for
dealing with this? I'm fully aware of nested/logic tags but
if they are the way I can't see how.
Suggestions would be appreciated, Thanks!

(1) client side code won't be able to utilise the struts tags and as such I won't know what values to set the appropriate input text element attributes to. (2) It is highly likely that even if I solved problem (1) that it would result in a IndexOutOfBounds exception, or just not bother with the properties from the new fields. Has anyone else solved this? Does struts have a mechanism for dealing with this? I'm fully aware of nested/logic tags but if they are the way I can't see how.

Re: ValidatorUtil deprecated?
Raible, Matt wrote: I just downloaded and installed Struts from last night (6/02/2003). Now I'm getting deprecation errors for ValidationUtil, yet the API docs say nothing about what it's been replaced with (http://tinyurl.com/dac9). Any ideas? Also, ValidatorResources has a couple deprecated methods too. ValidatorResources.get(java.util.Locale,java.lang.Object) .getFieldMap() Your probably talking about commons-validator ? Struts 1.1 will ship with the 1.02 version of commons-validator not the 1.1 version. So I would say this is a bug in the Validator docs, they should point to the equivalent method in the new class. There are two ways to keep up with this: 1) Subscribe to commons-dev to get the commit messages or 2) Look at an old example that uses ValidatorUtil method then see what new method is used. 3) Using the old source code take a section and do a global search for that code.

Re: Struts 1.1
[EMAIL PROTECTED] wrote: So, my question is, what exactly are we waiting for for the Struts 1.1 release? What can we do to get it there as soon as possible? We'd be willing to put some time into it to get it released. Using it in our production applications is out of the question though. I know this is a little harsh, but I have lost count of how long we've been waiting. At least 7 Struts books have been released since Struts 1.1 beta was released. (it's funny that all of them say that 1.1 will be out once the book is in print. :) Other web frameworks have gone from nothing to having released software during the beta of 1.1. I want quality software as much as the next guy, but was Struts 1.0 so poorly designed that it takes so long to come out with the next MINOR version? OK, flame away, but I hope we can get someone tell us exactly what we need to do to stop the hold up and get 1.1 released. Please let us know. I'll qualify this by saying I have not been in the release loop but here are my 2 cents. Martin has been working very hard on several packages in Jakarta-Commons. I believe at this point that commons-fileupload will go to a 1.0 final with known unsupported containers, such as zOs. Then struts 1.1 will go out. So for short term what you and other could contribute is mapping any know shortcomings in the nightly build by: 0) Contribute your time and experience doing: 1) Testing is always welcome under different containers. Make a entry under the Wiki to note what functionality was tested and under what container. There isn't currently a section for that but you could organize one. These results would eventually go into the official struts documentation. To facilitate Struts 1.2 to come out faster: 2) Use Bugzilla to find all open tickets, marked 'later'. Browse through them and see if improvements in the code that is suggested would benefit your project. If so then develop a patch that implements the fix and attach that to bugzilla. 3) Improvements to docs are always welcome as are diagrams, UML, etc... -Rob - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

bean:write / HashMap
Hi, I have checked struts documentation, including the index properties page, and cannot find the answer to this. I simply want to output some values stored in a hashmap without using scriptlets - ideally with the bean:write tag. Instead of doing this: %=myHash.get(NAME)% I would like to do something like this, but it doesn't work: bean:write name=myHash property=[NAME]/ ( but hopefully it serves to demonstrate what I'm trying to do ) I also tried this, but I'm just clutching at straws now: bean:write name=myHash[NAME]/ Using bean:write would be nice becuase it html encodes stuff without me needing to do anything. Using a bean instead of the HashMap would be a nice solution, but time constraints mean that the HashMaps need to stay for now...

Re: URL Validation with Struts validator
I started coding a URL client/server side validation 2 weeks ago, that I hope to contribute to the Validation framework. I put it on hold while getting other work finished before going on vacation. I modeled it on the email validation items, and used the w3.org definition of A URI to write the validation code. If all elements are there my code can tell if it is a valid URL, however I can't figure out when testing for a URL regular expression pattern how to make some items optional, it may not be possible, any Perl/PHP people out there ? The Unit tests I created are extensive and test all possible combinations, but take almost a 2 minutes to complete :( ! I have just come back from vacation and hope to have it finished by next week. If you want a quick and dirty method then go to javascript.com and look for some of their URL validations items, turning them into Java is easy to achieve using the ORO package.

RE: Any good suggestions on implementing Security
On the free side of things, I believe you could use a JNDI Realm in Tomcat for this purpose. You would need to roll your own SOAPInitialContextFactory and use that in the configuration of the JNDI Realm. Weblogic has an implementation of a SOAPInitialContextFactory: http://edocs.bea.com/wls/docs61/javadocs/weblogic/soap/http/SoapInitialConte xtFactory.html that may be configurable as part of a Weblogic security realm as well. -Rob -Original Message- From: Tony Baity [mailto:[EMAIL PROTECTED]] Sent: Thursday, February 13, 2003 9:57 AM To: Struts Users Mailing List Subject: RE: Any good suggestions on implementing Security Craig, Would you by any chance know anyone/anyproduct that instead of using JDBCRealm has create a SOAPRealm where the user data is available via a web service instead of a database?

For Tomcat specifically, this can be done easily if you use a JDBCRealm to get user and role information from a database. Then, writing an admin program to manage users is just like any other database maintenance application -- just make it update the same tables that JDBCRealm is using to authenticate and authorize users. Struts also has some built-in support for checking roles dynamically during execution: * You can use a roles attribute on an to limit which users can execute that Action. * You can use to conditionally display parts of your UI to only people that have the role you specify.

RE: Any good suggestions on implementing Security
+1 on the ServletFilter approach. Even better if you can get container managed security to meet your needs. Depending on the container, your groups and group memberships can be dynamically mapped to roles, with declarative specification of what resources can be accessed. This approach is optimal because the security context can be shared down to the EJB tier (and even to EIS, depending on your system) for tighter top-to-bottom security. This didn't meet our needs, so we went a step further with a ServletFilter. This is nice because it puts all of your security in one place rather than sprinkled across a variety of Actions, ActionMappings, etc. If you have access to a servlet 2.3 container, use this as your second option. Programmatic security built into your Struts-related code should be a last resort, and I can't even think of an occasion where it would be justified (unless the other two options aren't available, in which case I'd suggest you put effort into an upgrade instead). -Rob -Original Message- From: Rao, Nagraj [mailto:[EMAIL PROTECTED]] Sent: Wednesday, February 12, 2003 9:53 AM To: 'Struts Users Mailing List' Subject: RE: Any good sugestions on implementing Security Well the best approach I can think of is to keep it separate from the MVC model.

I did not think so. Our needs our very similar. The users with a admin page that allows them to change access to pages. I haven't used Tomcat to do it, but it appears that this document addresses some of the details: http://www.jaydeetechnology.co.uk/planetjava/tutorials/server/SecuringJavaWe bApplications.pdf It looks like you can use JDBC, XML files, or JNDI (allows LDAP) to retrieve your users, etc. This didn't meet our needs, so we went a step further with a ServletFilter. This is nice because it puts all of your security in one place rather than sprinkled across a variety of Actions, ActionMappings, etc. If you have access to a servlet 2.3 container, use this as your second option. Is this checking based on checking the requested the action_mapping against a dynamic list of allowable action_mappings? Is there an area I can look that suggests how to implement this type of dynamic security with a servlet filter? I didn't have anything to follow, but it sounds like declarative security via Tomcat can meet your needs. In my implementation, users belong to groups (roles), and groups are authorized for resources matching certain patterns. We store a list of resources a user is authorized for in their session (there is also a list of globally accessible resources), check the attempted URL against the user's list, and process or deny the user's request based on that. I don't know that it's the best implementation, and overall, I'd say to stick with container managed security. Our need to go beyond CMS was caused by a requirement to run different sites with different user groups from within the same web-app. We were concerned about the security implications of a user being authenticated with certain privileges being able to access sensitive data on another site.

RE: LookupDispatchAction
The keys in your KeyMethodMap should correspond to messages in your message
bundle used to render the button. So you would have in your jsp:
html:submit
bean:message key=button.add.banana/
/html:submit
in your action:
protected Map getKeyMethodMap(ActionMapping mapping,
ActionForm form,
HttpServletRequest request) {
Map map = new HashMap();
map.put(button.add.banana, addBanana);
map.put(button.delete.banana, deleteBanana);
return map;
}
And in your message-resources file:
button.add.banana=Add Banana
button.delete.banana=Delete Banana
If you don't need the message resources (for i18n or something), you might
want to use DispatchAction instead.

Subject: LookupDispatchAction
Does anybody know why the following is casuing me so many problems.
I'm using LookupDispatchAction and have a number of methods defined
in my action class including an execute method. The problem is that
the execute method ALWAYS gets executed and not the intended method.
I have in the addbanana.jsp:
html:submit value=Add Banana property=action/
and in Struts-config:
action path=/addbanana
type=com.example.AddBananaAction
name=BananaForm
input=/addbanana.jsp
scope=session
parameter=action
/action
In my action class I've defined the following:
public ActionForward addBanana(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws
IOException, ServletException {
return (mapping.findForward(success));
}
public ActionForward deleteBanana(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws
IOException, ServletException {
return (mapping.findForward(success));
}
/**
* Get key method map just obtains the map that maps the button
* text onto the particular method in this action
* @param mapping is the action mapping
* @param form is the action form
* @param request is the http request
*/
protected Map getKeyMethodMap() {
Map map = new HashMap();
map.put(Add Banana, addBanana);
map.put(Delete Banana, deleteBanana);
return map;
}
/**
* Execute method
* @param mapping is the information regardin gthe URI mapping and the
action
* @param form is the action form used
* @param request is the request

* @return the action forward, a destination to forward the user onto (eg
another JSP)

public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws
IOException, ServletException {
Logger.logInfo(Execute Called);
//We can now put these bits in the database
return (mapping.findForward(success)
}
Does anybody know why EXECUTE is called but the intended ADDBANANA method is
not
called?

Re: Design Questio
Justin F. Knotzke wrote: Hi, I am sure this is a basic question. Take a situation in where we have 2 JSPs, 2 ActionForms, and 2 ActioForward classes: a.jsp b.jsp ActionFormA.class ActionFormB.class ActionForwardA.class ActionForwardB.class a.jsp has form who's action parameter calls ActionForwardA.class with ActionFormA.class as it's form object. ActionForwardA.class does some happy-happy stuff and then calls b.jsp. Correct me if I am wrong but b.jsp will be called using ActionFormA.class's data. Keeping in mind that ActionForwardA.class requires data from ActionFormA.class, what do I do if I want b.jsp to be mapped to ActionFormB.class? The pattern that the struts example uses is EditAAction SaveAAction --EditBAction SaveBAction \ / \/ \ / \ / \/ / \/ / (AActionForm) + A.jsp (BActionForm)+B.jsp To keep your code maintainable after SaveAAction is 'happy' It looks up the 'success' or 'happy' mapping in your struts-config.xml That maps to EditBAction which takes care of filling in the data for BActionForm, and then forwards to b.jsp. All this is covered in Ted Husted's 'A Walking tour of the struts example'. in the resources section of the Struts web site, it is also included in the 'struts-documentation' web application in the binary struts download. Taking the time to look at that explaination of the 'example' included with struts, look at the code and trace through the program flow, and after some digging you'll get an AH or two that will be worth it. -Rob P.S.

RE: how to access a specific object inside a List efficiently
The problem you're hitting is that there's really no concept of a key in a List - it's just an ordered collection of objects. The closest you'd find is the contains( Object o) method, but that looks for the entire object and not just a key. I would suggest using a HashMap for what you're looking for. As for the break on logic:iterate, I think the closest way to approximate this is by setting up a flag for the loop such that you can do this: set up loop flag logic:iterate logic:equals name=loopFlag value=true (do important stuff) /logic:equals set loopFlag to false when criteria are met /logic:iterate This won't save the loop iterations, but will keep extra content from being written after you meet the criteria. If possible, however, you may want to trim your data set in the Action before you ever get to the jsp. -Rob -Original Message- From: Derek Shen [mailto:[EMAIL PROTECTED]] Sent: Wednesday, February 05, 2003 12:51 PM To: [EMAIL PROTECTED] Subject: how to acccess a specific object inside a List efficiently I have trouble to access a specific object inside a List based on a key.

RE: How to access a valueObject inside a Map?
I think a shift in how you approach your JSPs and Actions will get you the most mileage here. It seems that by storing this map in session, you're trying to get around ever creating any additional references to it. What I'd suggest is that you handle this in your Action. In your action, fetch the object from the map using the key, then store that valueObject in the request. The page can then access the object using the request-scoped bean. I think you're trying to do too much through the session/page combination, and not enough in your Action. -Rob -Original Message- From: Derek Shen [mailto:[EMAIL PROTECTED]] Sent: Wednesday, February 05, 2003 5:18 PM To: [EMAIL PROTECTED] Subject: Re: How to access a valueObject inside a Map?

RE: [Tiles] loses current url
I think to solve your problem, you're going to need to define the problem in broader terms. A redirect is much like a forward, except the client doesn't know about it. Once the Action has executed and mapped to a page, a redirect is executed (unless you specify a forward). Either way, what this means is that after Struts finds the URL to access after it processes your action, the request is against that JSP, and the previous request URL is gone from the HTTP headers. What's the overall problem you're trying to solve? That may be a better approach, because given the parameters of the current problem, you're walled in with nowhere to go. It sounds like perhaps you're trying to solve some sort of navigation or form population problem? -Rob -Original Message- From: Kevin Tung [mailto:[EMAIL PROTECTED]] Sent: Wednesday, February 05, 2003 5:05 PM To: Struts Users Mailing List Subject: RE: [Tiles] loses current url Ok..

When downloading a struts version always refer to the version of the docs that come with that download. The docs on the web site tend to reflect functionality of the current nightly build.

Re: error checking in Action
David Graham wrote: Why do you need to move error checking into an action? Why not just let the form bean do it's job and validate itself? Have you looked at using the validator? Validation belongs in the form bean; actions' main job is to direct traffic and execute business layer methods. David Agreed, For Generic type of validation the ActionForm is an appropiate place to do validation. To restate what David said, the ActionForm is designed to be passive, and have values info it needs passed to it. It should definately not make method calls to other Business Logic. To add to that,Any complex validation would take place in the Business Logic, with the Action being the go between loading and unloading the ActionForm and calling validation methods in the Business Logic. -Rob -- To unsubscribe, e-mail: mailto:struts-user-unsubscribe;jakarta.apache.org For additional commands, e-mail: mailto:struts-user-help;jakarta.apache.org

Comments inline, also see: http://nagoya.apache.org/bugzilla/show_bug.cgi?id=13526 Peterkofsky, Don wrote: I'm not sure of the background on this thread, but there may be some misunderstanding with this. I looked at the canned rule sets, and was confused by the use of the depends attribute in the rules file, which appears to be the same as the depends attribute in the validation file. However, my experiments showed that the required dependency in the rules file doesn't have the effect/behavior that you would assume, like the attribute in the validation file. The required dependency in the rule set did not appear to evaluate the required rule; in other words, when a rule is used in the validation file, and the rule definition has the required dependency, it does not seem to embed the required rule in the evaluation. For example, I could use the maxlength rule, and leave the form field empty, and no validation error would result. My interpretation of this is that the required dependency in the rules file has a different meaning than in the validation file, or perhaps is not used. If anyone has a better understanding or contradictory experience I'd be interested to hear and understand. Thanks for your experimentation, I had suspected something like this. In July patches were applied to the Validator that changes its behavior. Specifically it no longer ignored blank fields. I was waiting till this weekend when I get a solid block of time, so I could analyze the intent and purpose of these rules. I believe James Turner asked a similar question back in July and Dave replied that 'depends' determines if the field is evaluated individually, or all together with the form as a whole. Like I said I will take a better look at it this weekend. I am still new at using the Validator so right now what I say needs to be 'taken with a grain of salt', evaluated by considering my experience. -Rob -Original Message- From: James Turner [mailto:turner;blackbear.com] Sent: Tuesday, October 22, 2002 12:24 PM To: [EMAIL PROTECTED] Subject: Validator and required dependency At 11:33 AM 10/22/2002, Eddie Bush [EMAIL PROTECTED] wrote: Point noted :-) I'll let someone else explain what the rationale was for doing that.

Looking a little further at the CVS logs a patch to the validator-rules.xml
was applied on July 17 2002, that when checking for a value
that changed the code from:
if (!iValue || !(iValue = -128 iValue = 127)) {
to
if (isNaN(iValue) || !(iValue = -128 iValue = 127)) {
This is done in about 8 places in the file.
This could be causing the difference in behaviour, try reverting
the code to !iValue.
Let me us know if the behaviour returns to what it was before.

Re: Struts taglibs without Struts
[EMAIL PROTECTED] wrote: The problem with trying is that whilst you can prove that some tags work, it is much harder to prove that all tags in all taglibs will work. For that you need knowledge of the architecture. Someone who had this knowledge sent me the answer. Originally, the answer was yes. I am sure struts 1.0 tags will work outside of struts. However, in 1.1 the ApplicationConfig objects were added for application modules, and so there will probably be cases where they won't work. Now that the JSTL is out, use those tags first. -Rob -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

url parameters not being copied to form bean
I'm not sure why but I have parameters that are not being copied to my form bean.

Re: Dynamic number of form fields
There was a good tutorial on this possibly linked from the struts page titled Monkey Struts. I found it to be quite good, very easy to follow. David Graham wrote: I want to have a form with a variable number of input boxes. For example, a simple edit person form that has a first name and last name input box for each person in your db. So the first set would be named firstName_12 lastName_12, the second set might be firstName_45623 and lastName_45623. The number after the underscore is the personID from the db table. When the form is submitted you loop over these fields and update the appropriate row in the database from the _ID info. I've read through the docs on DynaBeans and that seems like the way to go but I'm still not sure how to go about this. When populating the DynaFormBean, does struts just go through the request params and assign them to new form properties? How would you validate this type of form?

Re: Directories and Files structure for sub applications
Does anyone have a best practices suggestion for how to organize the directory and files structure for a Struts application composed of sub applications? I don't know if there is a best practices yet. Here is what I have done. Our source tree looks much like the struts source tree src/ java/ test/ web/ portal/ module/ catalog/ - application module (sub-app) src/ java/ test/ web/ portal/ catalog/ WEB-INF/ struts-catalog.xml tld/ catalog.tld So the modules tends to be grouped together. What we really need though is a generic build-module.xml I started to modify the struts build-webapp.xml a few months ago, but never had time to finish it.
