Re: Problem in validation?
This can be validated using the basic validators provided by the struts framework itself. just specify the validators you want (like required, minLength, maxLength etc) in the validatior-rules.xml and associate this with your form using the validation.xml file.

Struts modules does not work with Tiles, is there a tiles plugin problem?
Hi ! I have two web applications developed with Struts that are linked together using the struts modules. The pages worked well but after we have passed to Tiles when we try to do the integration via the same procedure, i mean the struts modules, seems that the tiles plugin is never called as the second tiles definition (the one for the module) seems that is never read. Does anyone 'meet' this situation ? How can I solve this? Many thanks, Ionel Condor.
RE: Struts modules does not work with Tiles, is there a tiles plugin problem?
This is just a guess - (I have no idea what Im talking about ,I just remember seeing this somewhere) - do you link straight to your JSPs? If so you wont hit the controller (tile request processor) so it can get confused when modules are involved. You might need to use a SwitchAction or something like that? (but like I said, Im not really sure (dont use tile myself) and so thats all just a guess based on hearsay :-) -Original Message- From: Ionel D Condor [mailto:[EMAIL PROTECTED] Sent: Monday, 21 July 2003 14:47 To: Struts Users Mailing List Subject: Struts modules does not work with Tiles, is there a tiles plugin problem?

Struts MVC framework similar to that of a servlet container?
Hi. I've been using Struts for a long time, and I've been very happy with the framework. However, a recent discussion on Sun's Java forums has left me wondering if Struts is necessary. It seems that the servlet container itself provides an MVC framework very similar to that of Struts. All that is missing is some utilities and standardization. I was wondering if there is a flaw in my logic below, and if anyone had any comments. In comparing these two MVC frameworks, the servlet container would be the equivalent of the ActionServlet. They both read their configuration files, examine the incoming URL, and then forward the request to the configured handler. In the case of the servlet container the handlers are Servlet classes, and in the case of Struts its the Action classes. Both the container and the ActionServlet will create an instance of their handler when its requested the first time. The Servlet's service method and the Action's execute method will call some domain logic and then select a view to display to the user. The Servlet can use RequestDispatchers to encapsulate information about the view, and the Action will use an ActionForward. Doesn't this sound very similar? It seems like we are adding a lot of complexity on top of the servlet spec in order to get some common tasks done for us. But that could probably be better done by the servlet container itself. For example, Struts automatically populates the form class the developer specifies for a particular Action. But Sun could provide a standard Filter implementation which does the same thing. You can declare handlers for your exceptions in the Struts configuration file, but you can also do it in the web.xml. If the functionality there is not quite the same, Sun can add a little to the spec and we would get it. My question is, is an application built in Struts really that much more maintainable than one built with servlets? Or if some common utilities provided by the Struts container were provided by the servlet container, would there be much difference? It seems that would even be simpler. Or not? ranko - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Struts MVC framework similar to that of a servlet container?
hi, No doubt, they are vaguely the same. After all STRUTS is based on container. BUT struts make your life EASY. How? By providing scalable and reusable code - base principle of frameworks. 1. Frameworks are the semi-complete applications. They are standardized answer to the very common set of requirements that almost every application faces in it's life cycle. 2. Containers provide some *services* within some *boundaries*. So does STRUTS, but in more refined standardized form. If you see around, there is always some base code. APIs - Base libraries - Facades and so on. Some one writes an encapsulation to make his job easy AND still there is someone who may like to write more encapsulated code. You will definitely find discussions on this list about extending Action class. Why is that? Everyone knows. There are always some set of requirements that occur more frequently and they need to put together as reusable piece of code and that's why STRUTS is here. regards Navjot Singh |-Original Message- |From: Ranko Bijelonic [mailto:[EMAIL PROTECTED] |Sent: Monday, July 21, 2003 12:42 PM |To: [EMAIL PROTECTED] |Subject: Struts MVC framework similar to that of a servlet container? | | | |Hi.

validator sequence execution
hI,
i have something like this my validation.xml
field property="cwbPrice"
depends="required,float,floatRange,mask"
arg0
key="cwbPrice.displayname"/
arg1 name="floatRange" key="${var:min}"
resource="false"/
arg2 name="floatRange" key="${var:max}"

name="mask"/
var
var-namemask/var-name

var
var-namemin/var-name
var-value1.00/var-value
/var
var
var-namemax/var-name
var-value99.99/var-value
/var
/field
but the execution order in my jsp is
return validateMask(form)
validateRequired(form) validateInteger(form)
validateFloat(form) validateIntRange(form)
validateFloatRange(form);
it is validating "mask" at the first place though i have mentioned it
in the last. is it the way the validator works or can i mention the
sequence elsewhere

RE: html:form in a html:logic
Hi, I think it's a pretty straight forward issue. You have given html:form inside inside the logic:equal tags. Now from your perspective the property 'aBoolean' cannot be other than 'true' or 'false'. But for struts there could be a value other than these two for which the html:form tag is not reached at all. So it says not properly used..

RE: XML To Database
hi, this is off struts but anyway... It's simple. Most of the recent developments in databases now supports XML-DB table mapping. So, it can be transformed automatically. For more details, search for xmldb on otn.oracle.com I have not done this before but as you are working can i expect words on implementation when you will be through? regards Navjot Singh |-Original Message- |From: Konstantina Stamopoulou [mailto:[EMAIL PROTECTED] |Sent: Monday, July 21, 2003 4:45 PM |To: Struts Users Mailing List |Subject: XML To Database | | |Hello everyone, |I have the following problem.

RE: error..!
There is really no code that shows that you actually attached the listdepartments bean to any of the contexts. Where do you do it? If you call your jsp directly then the error above is in deed correct. Before you are ready to display your content you have to set it up first. A good place to do it is in an Action. You can also do it in your JSP but then you would be scriptleting.

RE: error..!
Although u have listed down the errors its not clear what exactly you want to do.. I assume that u want to iterate over a collection of departments and print the name of the department. So here it goes logic:iterate property -Name of the property whose getter method returns the collection to be iterated name - name of the JSP bean, the getter method whose property getter returns the collection to be iterated So essentially 'property' will be your department name collection(Im not too sure whether this is listdepartments) and 'name' should be your ActionForm bean. However I cannot find that in your struts-config. Wondering how are you getting the listDepartments in the request. You should either have the form bean set in the struts-config or should be setting a listDepartments to the request. request.getSession().setAttribute(CommonConstants.DTO_IN_SESSION, listDepartments); I just used one of the codes which I am using inside my Action class where I don't have the actionForm bean.

RE: FW: Redirect to home page on logon
Thanks Rick.
I did something similar to that and it works. But, behind the scenes, still execution
is forwarded to the error page. Of course the filter intercepts that and corrects
things. But I still can't understand the error that occurs. I wrote that in a later
post, don't know if you've seen it.

I have an application that uses beans stored in the session context.
If the user's session times out, he's asked to re-login on his next
request. For this, I'm using J2EE security; I'm not doing it
myself.After the user is finished with the re-login, he's supposed
to complete his request, but the fact that the beans are not in the
session anymore produces an error.Unfortunately, those beans are
specific to the last request the user made, so I cannot re-initialize
them in a listener for session creation.
I was wondering if there's a way to configure security so that after
the user logs in he's redirected to a certain page instead of being
able to continue his last request.
I had the same problem.. here's what I do...
I use the servlet filter to authenticate roles and to bring me back to
the login if the role isn't set. To fix the problem with the Session
variables not being set I have ALL of my actions (which are dispatch
actions) extend a BaseDispatchAction. In this BaseDispatchAction I do
the check for a User bean being in Session scope in the
BaseDispatchAction execute method. If the bean is there, all is well,
and continue onward. If it is not it fowards the user to a SetUpAction
which in turn will forward them to the main page after the setup is
complete. (Of course if you want you could forward them back to what
page they were trying to go to if you app flow will allow it.. in my
case it was necessary to just always return them to the default home
page after login.
The execute method in the BaseDispatchAction looks like:
HttpSession session = request.getSession();
if ( session == null ||
(UserBean)session.getAttribute(userBean) == null) {
//foward user to the SetUpAction or page of your choice
return mapping.findForward(Const.SETUPF);}
else {
//all ok so proceed to doing standard dispatch action
return super.execute(mapping, form, request, response);
}

RE: Struts MVC framework similar to that of a servlet container?
I understand the point of frameworks, I was just wondering if the one Struts aims to provide one that is already largely provided by the container. -Original Message- From: Navjot Singh [mailto:[EMAIL PROTECTED] Sent: Monday, July 21, 2003 4:14 AM To: Struts Users Mailing List Subject: RE: Struts MVC framework similar to that of a servlet container? hi, No doubt, they are vaguely the same. After all STRUTS is based on container. BUT struts make your life EASY. How? By providing scalable and reusable code - base principle of frameworks. 1. Frameworks are the semi-complete applications. They are standardized answer to the very common set of requirements that almost every application faces in it's life cycle. 2. Containers provide some *services* within some *boundaries*. So does STRUTS, but in more refined standardized form. If you see around, there is always some base code. APIs - Base libraries - Facades and so on. Some one writes an encapsulation to make his job easy AND still there is someone who may like to write more encapsulated code. You will definitely find discussions on this list about extending Action class. Why is that? Everyone knows. There are always some set of requirements that occur more frequently and they need to put together as reusable piece of code and that's why STRUTS is here. regards Navjot Singh |-Original Message- |From: Ranko Bijelonic [mailto:[EMAIL PROTECTED] |Sent: Monday, July 21, 2003 12:42 PM |To: [EMAIL PROTECTED] |Subject: Struts MVC framework similar to that of a servlet container? | | | |Hi.

RE: Struts MVC framework similar to that of a servlet container?
there's a lot of stuff it gives you out of the box. 1. solid code so does the container i guess. 2. validation framework This is one of those changes that could be added by way of utility classes. Have that Filter that autopopulates, check for correct types like Struts. 3. tile framework You can use it without Struts 4. auto-population framework It should be easy to add a Filter that autopopulates a configured form (not every time but as a standard). 5. role based actions I'm not sure what this is. 6. xml configuration of all the links or actions of your application So does web.xml i guess. 7. best practices framework bundling (scaffolding) complete with examples (many years of experience went into this one). Same thing as above. There are tutorials, examples, etc... 8. ease of use If you think of a Servlet as an Action its kind of as easy. Except for some repetative tasks that I would include to complete the servlet spec (rather than rewrite some of the container functionality to add those utils). -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Monday, July 21, 2003 8:42 AM To: Struts Users Mailing List Subject: Re: Struts MVC framework similar to that of a servlet container?

RE: Struts MVC framework similar to that of a servlet container?
hi ranko, Assume you don't use struts. You start writing your first app for your requirements. Being an expert programmer, you have done with first one by wriitng lots of utility classes and base code. Now you start with second. You will realize that the second app can use most of the functionality (except business logic) from the first app. NOW WHAT? You will dig out some code from first app that can be RE-USED in second app. That code can be called a framework(;et's call it RANKo framework ;-) and that's precisely what STRUTS intends to provide. Anyway, it's your viewpoint. Being a creator of one servlet/xml/xslt based framework myself(almost 18 months back), I know what is *common code* required for *most of the apps* and the efforts/time needed to create that framework.

clicking a hyperlink to populate a field
Hi all, This is what I want to do: A user will enter part of a school name in one field on an ActionForm and part of a school address on in another field on the same form. The user then clicks on a find school button which opens a new page and lists a collection of matching candidate schools by doing an SQL SELECT query based on what the user has entered on the previous ActionForm. I want the school name to be a hyperlink so that the user clicks on the matching school name in order to populate the school name and address fields on the previous ActionForm.

getting an ActionMapping class from within a custom tag
Hi, What: I would like to find the roles associated with an ActionMapping from within a custom tag, but I only have the action name so I guess I need to get an instance of the ActionMapping class. How can I do this? How do I get an ActionMapping class, given the name of the action? Why: I want a generalized way to hide links to actions that the currently logged-in user doesn't have access to. So what I plan to do is subclass the html:link tag-- my subclass will check the current user's access to the action for the specified link, and either hide it, or print only the link text.

RE: clicking a hyperlink to populate a field
Sure, this is what I do. An easy way: Use Javascript. When you pop up the window and user finds his/her school you need to put the following code in your link onclick event: Javascript: parent.document.form ['formname'].schoolField.value='Whatever the name of your school'; window.close (); return false; - or something like that I can't remember my JS stuff exactly but you get the idea. You can probably evenrwrite a function for this since you might need to set more than one field (schoolId probably, school location etc.) Now the parent window is supposed to have the form and schoolField is text that is disabled and there is a button next to it that actually pops up your popup window, to allow your user to select the school. A more complicated way would be to forget about pop ups and keep track in the session of where the user at in the process of selection the school. Once request comes that you can be happy with (school is selected) you just shoot the first form back. The advantage of this method is that you do not rely on JavaScript. Disadvantage is that your logic becomes more complicated, as your request might spawn more than one form.

Using the validator for client side field modifications
Hi. I've been reading through some of the documentation and I haven't found exactly what I'm looking for. I'm sure (famous last words) that this is possible, but I need confirmation for a presentation I'm making. I have a form with text fields that I need to convert to upper case, verify they contain only numbers, etc., but I need to do it real time, i.e. using onBlur (this is due to the fact that I am converting an existing application and need similar functionality). The users want to see the fields converted and checked when they tab/click out of the fields. I have been reading about the validator and the validator:javascript formname=myForm / onSubmit=validateMyForm tag combo, but I'm not sure it does what I want as it seems to be doing a *form* validation. Could someone point me in the correct direction? My goal is to consolidate all the javascript into the validator.xml file so I can reference it by name. Should I just be using a simple javascript include instead? Thanks, /greg -- Gregory F.

I guess the main difference between what you mention and struts is that you can use this stuff right away for the app you want to build without modification.

Both the container and the ActionServlet will create an instance of their handler when its requested the first time. The Servlet's service method and the Action's execute method will call some domain logic and then select a view to display to the user. The Servlet can use RequestDispatchers to encapsulate information about the view, and the Action will use an ActionForward. Doesn't this sound very similar? It seems like we are adding a lot of complexity on top of the servlet spec in order to get some common tasks done for us. But that could probably be better done by the servlet container itself.

Subject: paramId in html-el:link tag - Referenceing a Constant
Date: Sun, 20 Jul 2003 14:43:25 -0700 (PDT)
The struts-example\registration.jsp contains the following code:
html:link page=/editSubscription.do?action=Create paramId=username
paramName=registrationForm paramProperty=username
bean:message key=registration.addSubscription/
/html:link
Switching this to an html-el:link tag is easy.
html-el:link page=/editSubscription.do?action=Create paramId=username
paramName=registrationForm paramProperty=username
fmt:message key=registration.addSubscription/
/html-el:link
The value username is a key, so it might be better to reference a constant
value:
Constants.USER_NAME_KEY. My question is, how do I do this (without using
sriplets)?
If I don't use a quote after paramId=, I get an error when the page
compiles. No matter what I
put inside the quotes, it comes into the html as literal.
Any suggestions?

Re: dificult problem, preventing population (repost)
I guess the issue is the same one you mentioned earlier which is that we have to know which action is preparing the token and which one is checking it.

I guess that is the original question, but the more I think about it the more I'm curious to know what the options are. I suppose what was mentioned before about using mappings and subclassing ActionMapping may be the only way? (This is essentially what workflow does) One possible way is to add a method prepareExecute() in the action base class. After the RequestProcessor obtains the action mapping and before populates the form bean, it invokes the prepareExecute() method on the action class. If it finds anything wrong after the prepareExecute() call, it throws an exception. This way would return the logics to handle the tokens back to action developers. Is this reasonable?

How to get MessageResources in ValidatorForm
Hi, I need to get the MessageResources (i.e., application.properties) while I am in the validation of my ValidatorForm (i.e., validate(...)). The only way I have seen is to get it from the ActionServlet (servlet.getResources()), but that is deprecated... What is the new way?

Sorry guys this is not a struts question but i'm hoping someone on here

Any Ideas as i'm going crazy now I've tried upgrading to xerces
2.4.0
but i still get the same error.
I suspect that it really is related to your XML parser ... this looks
suspiciously like a bug in earlier versions of Xerces. It turned out that
one of our Struts DTDs had a comment line longer than 80 characters, but
caused Xerces to output a totally bogus error just like this, pointing at
a place totally unrelated to where the problem really was.
Note that, if you're using JDK 1.4, simply putting Xerces 2.4 into your
classpath does *not* replace the use of the built-in parser. You have to
put it in the endorsed standards directory ($JAVA_HOME/jre/endorsed I
*think* -- it's in the JDK docs), or use a system property to declare the
directory containing this JAR to be your endorsed directory.
To use an updated parser in Tomcat 4.1 or later, put it in
$CATALINA_HOME/common/endorsed.

html:form tag and coupling between ActionForm and Action
Hi, Does anyone know why the name and type attributes of the form tag are deprecated? It seems to me that a tight coupling between a jsp and it's associated ActionForm makes more sense than coupling the ActionForm with the Action, which is the consequence of the putting the name attribute in the ActionMapping. What if you want to write an Action that can service a family of several different ActionForms?? Any help or insight would be appreciated. Thanks, -Chris __ Do you Yahoo!? SBC Yahoo!

RE: Struts MVC framework similar to that of a servlet container?
ok. assume i go through the process below. now i have RANKo framework :) (which I did actually). Then I learn about Struts and say, hey this serves the same function as my framework, let me switch to that cause everybody uses that so its standardized in some way. Then, some time later you realize (perhaps wrongly) that it duplicates a lot of servlet container functionality and that the MVC part of this framework is already there. That's why I'm asking myself how is writing a Servlet different from writing an Action. For every Action in a Struts application I can write a Servlet. Instead of putting my mappings in struts-config.xml, I will put them in web.xml. Now, I know there is some other common code that is currently not in the servlet spec, but is in Struts. My question was is it better to add some of those to the servlet spec, rahter than rewriting part of it. Or, second scenario. Let say I'm using Struts. Then I write an Action that manages these Task objects. I have a configuration file for different Task objects. I write an abstract Task class which different Tasks can extend. My Action is the controller for all the Tasks. I figure out which task to call examining the URL. Over time, I add to this framework to make it easier to use. So now i have a task-config.xml where I specify all my Tasks. I have TaskAction (a controller). And bunch of 'utility code'. Then I ask myself, is this that much different from the Actions Struts provides? Note that I'm not necessarily saying this is the case, just asking for some reasons why that is not the case. General information about frameworks and how they come about does not address the specific question of wheter this particular framework duplicates a lot of functionality of its parent environment.

All that is missing is some utilities and standardization. I was wondering if there is a flaw in my logic below, and if anyone had any comments. In comparing these two MVC frameworks, the servlet container would be the equivalent of the ActionServlet. They both read their configuration files, examine the incoming URL, and then forward the request to the configured handler. In the case of the servlet container the handlers are Servlet classes, and in the case of Struts its the Action classes. Both the container and the ActionServlet will create an instance of their handler when its requested the first time. The Servlet's service method and the Action's execute method will call some domain logic and then select a view to display to the user. The Servlet can use RequestDispatchers to encapsulate information about the view, and the Action will use an ActionForward. Doesn't this sound very similar?

Resetting inputparameters to a jsp-page?
Hi,
Is there an easy way to reset inputparameters?
I use them like this
input name=dato type=text class=small id=dato size=5
maxlength=5 value=c:out value='${param.dato}' /
The problem is that a reset-button will not reset the fields when using
jstl. I have a feeling this is not possible but I just want to ask.

RE: Struts MVC framework similar to that of a servlet container?
for my $0.02. Using just pure servlet and base JSP, dealing with forms is not intuitive or clean. You either rely on too much code in a JSP, or too much reading and parsing at the start of your servlets. And, the development cycle increases as your changes increase. I find the Struts mode to be clean and simple. Need to change a field, add a field. Change one class (the ActionForm, or not at all with a dynaform), modify the .jsp presentation. And then account for the field change in the business logic. Combine it with XDoclet, and you've got immediate Data/Value Objects that can be generated from the ActionForm itself, ready to be passed back to your EJB level code (using CMP, you never have to account for the field in the logic, unless you're doing business level decisions). The mechanisms in place for detailing messages back to the user (ie, ActionErrors) are very clean, easly integrated with field-specific messages. Seamless integration with Java's i18n functionality. I'm looking for the reasons why this would not be the case. Are you looking for where using the base Sevlet layer is more advantageous over using Struts? Or, are you looking for areas that Struts just doesn't handle, leaving a gaping hole? Are you being persnickity, or is there a serious question/concern ?

RE: html:form tag and coupling between ActionForm and Action
I don't think Daniel's idea will work.
If the action form does not exist then
struts wants to instantiate the form.
Therefore struts needs to know the type.
It might work if you have a session scope form already there.
I think of actions as the most dependent class,
i.e. nothing should depend on actions (no other classes should know anything
about actions),
actions should depend on everything (well not everything, but definitely the
model and the view).
Because they are such nasty beasts, (and because in struts they should have
no state),
they should be very small.
Since they are so small the architecture that puts effort into
making them generic and reusable may be misguided.

RE: html:form tag and coupling between ActionForm and Action
Actually I meant something like this:
Create BaseAction with three methods {
protected ActionForm createForm (
HttpServletRequest request,
String actionName) throws Exception {
ModuleConfig mc = RequestUtils.getRequestModuleConfig (request);
ActionMapping am = (ActionMapping) mc.findActionConfig
(actionName);
return RequestUtils.createActionForm (request, am, mc,
getServlet ());
}
protected void attachForm (
HttpServletRequest request,
String actionName,
ActionForm form) throws Exception {
ModuleConfig mc = RequestUtils.getRequestModuleConfig (request);
ActionMapping am = (ActionMapping) mc.findActionConfig
(actionName);
if ((am.getScope () == null) || (am.getScope ().equalsIgnoreCase
(session))) {
request.getSession ().setAttribute (am.getName (), form);
} else {
request.setAttribute (am.getName (), form);
}
}
protected void removeForm (HttpServletRequest request, String
actionName) {
ModuleConfig mc = RequestUtils.getRequestModuleConfig (request);
ActionMapping am = (ActionMapping) mc.findActionConfig
(actionName);
if ((am.getScope () == null) || (am.getScope ().equalsIgnoreCase
(session))) {
request.getSession ().removeAttribute (am.getName ());
} else {
request.removeAttribute (am.getName ());
}
}
}
You can use theese 3 methods in actions that need to Dispatch (that is
why my BaseAction extends DispatchAction). So you get request:
createForm you need, populate its values, attachForm and redirect to
the view you want to see it in. Be careful not to redirect to action
that uses the form you just populated, it might wipe out all work you
have done.
If you use application scope forms you would have to add it in. I never
do so it is not there.

Details : When I click on French Canadian | Francais Canadien - On the JavaScript Type Form the integer field should fall in a range of 100-200 and the date field should have a format of 'dd-MM-', Date field should be valid if I enter a date like ' dd-MM- '. However, it only valid 'MM/dd/'. So, when I click on JavaScript Type Form - with JavaScript Validation and Server Validation, the date field validation stay with 'MM/dd/'. If someone have the same problem, please send me an email at [EMAIL PROTECTED] cause I'm gonna be crazy!! I have tried jsType.jsp with : OS : WinXP and Win2000 Browser : IE 6 and Mozilla 1.4 Tomcat 4.1.24 JAVA 1.4.2 Struts 1.1.0 Thanks a lot!

Problem with ActionErrors
Hi, I am fairly new to struts and I am using struts1.1. I have some code which basically follows the LogonAction example that comes with the code. I use the message tag with id=error to view the errors. When the validator returns errors, they are displayed correctly. When my action saves the errors, I get a Cannot find bean error in any scope?? I am not sure of the exact wording of the error (reciting from memory). Sorry that I cannot provide more exact details, but the code is not available to me at this time. Has anyone seen this before or have any ideas on where to look to solve the problem. Thanks. Chuck - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Struts MVC framework similar to that of a servlet container?
I would not call it persnickety, although there is no immediate problem. My concern is that there is a lot of duplication of funtionality (if there is). If form handling equal to that of Struts was added to the Servlet specification (for example by providing a standard implementation of a Filter to do so given a configuration in web.xml), would it then be equivalent to Sturts? Basically, it seems to me that much of the framework that Struts provides is already provided by the Servlet specification. If the energy used to develop Struts was used to make JCP somehow make these ease of programing changes that are missing, would we end up with a much better, cleaner, and simpler framework? Or am I completely off here and the MVC framework provided by the container is really not the same as the one provided by Struts. Again, its a general question, I have no pressing need that needs to be addressed.

Using just pure servlet and base JSP, dealing with forms is not intuitive or clean. You either rely on too much code in a JSP, or too much reading and parsing at the start of your servlets. And, the development cycle increases as your changes increase. I find the Struts mode to be clean and simple. Need to change a field, add a field. Change one class (the ActionForm, or not at all with a dynaform), modify the .jsp presentation. And then account for the field change in the business logic.

A column consisting of html:select widgets
Dear All, I'm using struts 1.0.2. I have a requirement where i need to show a column consisting of dropdown lists. Every row of the table for the column shows a dropdown with the same list of options. I've used String[] getCategory() and setCategory(String[]) getter/setter in thr ActionForm. On the form submission i get the correct selected values for all the rows. Now my questions is how do I set the values of these dropdown from he database when the page is shown for the very first time. I've tried setCategory(String[]) setter, but the dropdowns don't show the correct option selected! I've also tried to search from the mail archive to no avail.

logic:iterate tag fails on large dataset, succeeds on smallone?
I am trying to do a very simple data-display web application using Struts, with MySQL on the back end. Basically, I take a ResultSet and its ResultSetMetaData and put it into some beans. I have a TableDataView object which contains a FieldList and a RecordCollection. FieldList has a property called fields which returns a List. RecordCollection implements Collection, and containts an ArrayList of Record objects; Record returns an array of the field value objects as the property fieldValues. My JSP page(showtable.jsp)looks like: html:html TABLE TR logic:iterate id=fields name=tableDataView property=fieldList THbean:write name=fields //TH /logic:iterate /TR logic:iterate id=record name=tableDataView property=recordList TR logic:iterate id=fvalues name=record property=fieldValues TDbean:write name=fvalues //TD /logic:iterate /TR /logic:iterate /TABLE /html:html If I run this on a small table, with 10 fields and 11 records, it works fine. If I run it on a large table, with 28 fields and 307 records, then I get: javax.servlet.ServletException: cannot find bean fvalues in any scope at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageCon textImpl.java:533) at org.apache.jsp.showtable_jsp._jspService(showtable_jsp.java:192) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:137) ...[deletia...I can't imagine that any of it has anything to do with my error] at java.lang.Thread.run(Thread.java:536) I can eliminate this problem if I reduce the number of fields in the table to 9 or 10, but I can't see why this should be a problem, and certainly not why my looping bean should suddenly become unavailable. My unit tests seem to be telling me that my Record bean should be properly returning a list of 28 field values. I don't know at what point things are breaking down. I'm not experienced with JSP tag programming, so I haven't been able to learn much from IterateTag.java, or the compiled version of showtable.jsp.

Re: logic:iterate tag fails on large dataset, succeeds on small one?
I suggest you use the JSTL's c:forEach tag instead of the Struts iterate tag. I have dynamic query pages that use forEach and display n number of fields with no problem.

RE: Struts MVC framework similar to that of a servlet container?
The fact is that the Servlet spec does not provide equivalent features to Struts. Struts wouldn't exist if the Servlet spec already had everything web developers needed. Ok, so Struts started with providing ActionServlet which forwards requests to handlers (Actions) based on its configuration file and the URL. But the container already forwarded requests to handlers (Servlets) basd on its configuration file and the URL. That's what I'm struggling with. It seems like the container,was lets say, 70% of the way there. A lot of functionality that Struts provide can be separate from its controller pieces. I guess we all think of a Servlet as an application entry point rather than just a handler equivalent to a Struts Action. I'm wondering why can't or shouldn't we think of the Servlet as an Action (with understanding that some utilities like form population, etc would need to be added there). ranko -Original Message- From: Adam Levine [mailto:[EMAIL PROTECTED] Sent: Monday, July 21, 2003 12:49 PM To: [EMAIL PROTECTED] Subject: RE: Struts MVC framework similar to that of a servlet container? for my $0.02.

If you've built it already, then you've defeated part of the purpose of adopting it, but not all. I don't understand when you say you want to re-write the servlet spec.

Open source software has certain advantages over standards because it is easier to try new things. It's *much* easier to change Struts than to change any Java specification including Servlets. But you should notice the huge influence OSS and Struts in particular has had over the standard technologies. Struts directly contributed to JSF and JSTL with ideas and pressure to make the standards better than the Struts version. IMO, that's a much more effective way of changing things for the better.

System.out.println(newList is + newListAsArrayList);
When I print this, I always get only one line (the first row which I put
in there as a default).
If anyone can help I would appreciate it. I have been working on this
several days and I am stumpped.

bean:write and the format attribute
I'm having a little bit of trouble using the
format attribute in bean:write.
I'm trying to use the FormatStyles as documented
in java.text.MessageFormat.
bean:write ... format={0, number, currency}/
and
bean:write ... format={0, date, long}/
But these are not working.
Is this not supported, or am I doing something
wrong? (final 1.1 release).

RE: Struts MVC framework similar to that of a servlet container?
You could certainly code each Action as a Servlet but it would take more work. I'm not sure exactely how it would take more work (provided there were Struts like utils writen one time). You've mentioned changing the Servlet spec several times and seem to be under the impression that it's easy to do. Open source software has certain advantages over standards because it is easier to try new things. It's *much* easier to change Struts than to change any Java specification including Servlets. But you should notice the huge influence OSS and Struts in particular has had over the standard technologies. Struts directly contributed to JSF and JSTL with ideas and pressure to make the standards better than the Struts version. IMO, that's a much more effective way of changing things for the better. Yes, that is true. We definitely benefited from Struts in many ways. But it just seems to be getting too encompasing. Now we have declarative exception handling that is configured in struts-config.xml, and we have it ( a weaker version maybe) in web.xml. Struts is becoming kind of self sufficient where everything is done through it even if it already can be done through something else. Its like a little container itself. But maybe i'm just temporarily mad :). ranko ranko -Original Message- From: Adam Levine [mailto:[EMAIL PROTECTED] Sent: Monday, July 21, 2003 12:49 PM To: [EMAIL PROTECTED] Subject: RE: Struts MVC framework similar to that of a servlet container? for my $0.02. Using just pure servlet and base JSP, dealing with forms is not intuitive or clean. You either rely on too much code in a JSP, or too much reading and parsing at the start of your servlets. And, the development cycle increases as your changes increase. I find the Struts mode to be clean and simple. Need to change a field, add a field. Change one class (the ActionForm, or not at all with a dynaform), modify the .jsp presentation. And then account for the field change in the business logic. Combine it with XDoclet, and you've got immediate Data/Value Objects that can be generated from the ActionForm itself, ready to be passed back to your EJB level code (using CMP, you never have to account for the field in the logic, unless you're doing business level decisions). The mechanisms in place for detailing messages back to the user (ie, ActionErrors) are very clean, easly integrated with field-specific messages. Seamless integration with Java's i18n functionality. I'm looking for the reasons why this would not be the case. Are you looking for where using the base Sevlet layer is more advantageous over using Struts? Or, are you looking for areas that Struts just doesn't handle, leaving a gaping hole? Are you being persnickity, or is there a serious question/concern ?

Okay I see what you are trying to do. Here is a suggestion from the top of my head: Create a new action class which uses the same form as the Action in question (populateDataSourceAction or something...). Use this class to load the data from the DB into the blockDataSource field in the form. Put the form in the request space like this in the Action: aRequest.setAttribute(anActionMapping.getName(), myActionForm) then forward it to the JSP page.

RE: Question on how to remove a detail row?
or, for those who aren't fans of having multiple forms. Add checkbox/radio
button (Depending on your business logic) to each row, obviously indexed to
the row #, and then place one button below the rows labeled delete/removed
selected item(s)

You could generate an onclick eventhandler for each button, parameterized
with the record ID, or some other data. Then when the button is clicked, it
can set a parameter (or hidden form field) that identifies the row.
