Setting values of nested collection
Hi all I have a problem with setting the values on a hierarchy of nested properties. I have an ActionForm which has a property A of type HashMap. A is keyed on Strings, and each value of A is a Collection (ArrayList). This collection contains objects of type B. I am trying to iterate through the keys A, and for each key, iterate through the corresponding value (which is an ArrayList of B objects), i.e. I am trying to do 2 levels of iteration. The I want to display a property of B and let the user change it. I am able to display the properties of object B on the screen. However, for some reason the nested:text tag doesn't work - the textbox is there, but the input does not populate the form. The following is what I am trying to do. nested:iterate id=idForA property=A nested:iterate name=idForA property=value !--this should access collection of B objects -- nested:text property=foo!--allow user to enter a property of B -- /nested /nested /nested The problem is that when I enter a new value for foo, nothing happens; the value of the nested property is not set. Is it possible to iterate through a HashMap, and let the user update its values? I am quite new to Struts, and have spent a lot of time trying to get this to work, but no luck. Any help will be appreciated! Thanks Danielle - ALL-NEW Yahoo! Messenger - all new features - even more fun! - ALL-NEW Yahoo! Messenger - all new features - even more fun!

NEWBIE: How to pass parameters between JSPs
Hi, Under some circumstances my app receives a set of request params at the login.jsp page. After the user has authenticated these params need to be passed to the next page to be displayed (home.jsp). home.jsp then displays differently depending on the params passed. Normally there will be no params at all. My original plan was to pass the params through to the login action (that gets called from the login.jsp) and then forward them to home.jsp by building a parameter ?name=valuename1=value1 string and appending it to the home.jsp url. My problem seems to be passing the params from login.jsp to the login action: 1. First, I tried storing the params in the request with request.setAttribute() in the login.jsp page. But, the login action gets a different request instance from that in which the request params were stored so the params are no longer there. (I could store them in the session I suppose but don't really want them there for the duration of the users session. Seems like it should be easier). 2. I then tried storing the params in the login actionform but for some reason this doesn't work either. I trawled through the mailing list archive - lots of oblique references to similar problems but nothing definitive What is the best way to do this? Is there a standard solution? TIA - Adam
Re: FW: R: Detecting the previous JSP
I strongly suggest to use DOM object model when programming
JavaScript, since I do it my applications are accessed from Safari,
IE, Firefox without problems and no browser dependent code is
required. In your case I'd do this:
1. The html form:
html:form action=/editRegistration
onsubmit=validateRegistrationForm(this) styleId=myFrm
Note that I have added the styleId attribute, this will be rendered as
an id attribute when html is generated. The id attribute identify your
html node in the node tree (in this case the form node).
2. The javascript function callDelete: we use DOM
(http://www.w3.org/DOM) to locate a node and change its attributes:
function callDelete() {
frm = document.getElementById(myFrm);
frm.setAttribute(action, /deleteRegistration);
frm.submit();
}
* With document.getElementById(...) you can locate an object of your
html document if it has an id attribute.
* With node.setAttribute(attributeName, value) you can modify the
value of an attribute or add it if it doesn't exists.
* And there are many other useful and simple methods you can use like
getElementsByTagName, appendChild ... Try this for more information

Re: ImageButtonBean LookupDispatchAction
Note, Ben, that in LookupDispatchAction we do the following: Used the mapping attirbute parameter method to find Delete It in the request object name/value parameter pair method='Delete It'. Created a reverse map of all the keys in the application resource property file for the users locale which allowed us to get button.delete from the key Delete It. We are not yet done. We then use the value button.delete as the key in a map we have coded into our LookupDispatchAction subclass to get the value delete. If this seems like a good idea to you, then we think differently.

Validation of Forms in a DispatchAction ???
Hi all,
I got a problem, I want to validate several Form in a

name=plateCreationForm
parameter=method
validate=true
input=tiles.plate.master.create.option
forward name=createFromFile
path=tiles.plate.master.create.confirmationMP/
forward name=createFromFileMPDP
path=tiles.plate.master.create.confirmationMPDP/
/action
public class MPCreateAction extends DispatchAction {
...
public ActionForward createFromFile(ActionMapping mapping,ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws
Exception {
DynaValidatorForm pcf = (DynaValidatorForm) form;
//retrieve the file representation
FormFile file = (FormFile) pcf.get(fileName);
ReadMP rmp = new ReadMP(file.getInputStream());
Collection collMP = rmp.read(); //Collection of MasterPlateForm
Iterator it = collMP.iterator();
while(it.hasNext()) {
MasterPlateForm mpf = ( MasterPlateForm ) it.next();
Enumeration enum = request.getAttributeNames();
mpf.validate( mapping, request ); // Where I call the validate
method
}
return mapping.findForward(createFromFile);
}
}
public class MasterPlateForm extends ValidatorForm {
.
public ActionErrors validate(ActionMapping mapping, HttpServletRequest
request) {
ActionMessages errors = super.validate(mapping,request); // This is
the line where the null pointer exception is called
String method = request.getParameter(method).toString();
if(method.equals(cancel)) {
return null;
} else {
return (ActionErrors) errors;
}
}
}
I wait your ideas !

Validate() vs JavaScript where is the advantage?
Hi, I'm wondering if I should use validate() method of ActionForm instead of JavaScript to validate the form. I can see the advantage of validate() when you have an internationalized application, but otherwise why would I have an overhead of going back to the server when I can do the validation on the client side? I'm a struts newbie so I might not see the advantage of validate yet, so can someone tell me why JavaScript would be an inferior choice ( when internationalization is not an issue ).

Thanks NK In short, you don't have control over your users' environment. They could be running old browsers; they could have JavaScript disabled; they could be running a browser with non-standard JavaScript support; their browser could be buggy. Malicious users could even manually assemble HTTP requests with invalid data. By using server-side validation, you take control over all of the data coming into your web application. If you leave validation to the browser, there is always the chance that bad data is going to sneak into your system and do something that you don't expect. -- Jeff - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Validate() vs JavaScript where is the advantage?
hi Nadia, What if the client who is accessing ur application disables the java script and keeps on hitting the server contineous ? Secondly, Using javascript its little difficult to modify the html pages. But using validate method and html:errors/ u can lay out ur error messages properly. At this moment I only see these two advantages of validate method. sachin -Original Message- From: Nadia Kunkov [mailto:[EMAIL PROTECTED] Sent: Thursday, September 30, 2004 6:35 PM To: Struts help (E-mail) Subject: Validate() vs JavaScript where is the advantage?

html:messages with multiple bundles?
hihi, has anyone a good way to handle displaying multiple messages that come from multiple bundles (resource files) on the jsp? how can i make my jsp handle messages that can come from more than one bundle? the reason why i need to do this is because we made a base application that all projects will include. this base application contains generic functionality that all future projects will inherit. so it has it's own bundles of messages, that has now come into the situation where it's possible that the returned ActionMessages or ActionErrors collection contains ActionMessage or ActionError objects with keys coming from the base bundles and the project bundles. ie. it is not guaranteed that all message collection keys will come from one bundle. any suggestions on how to handle this is greatly appreciated as always. please and thanks, woodchuck ___ Do you Yahoo!?

Hi Henrik Yes that's it. I tried what you suggest and it works. Many thanks. What I was trying to avoid was storing the params in the LoginForm actionform. It seems like this approach uses the LoginForm ActionForm as a forwarding mechanism for params passed into Login.jsp. What I tried was this: In Login.jsp itself I stored the params in the request instance via setAttribute(). If I later try to fish them out in the Login action they are not available - because the request instance has changed. I did not use the ActionForm to pass them from Login.jsp to Login Action.

Re: NEWBIE: How to pass parameters between JSPs
Hi Adam Glad it worked out. The ActionForm is the Struts way of interacting with HTML forms. It is a kkey concept of the Struts framework. So, what basically happens here is that an Action CAN be tied to a FormBean, and the FormBean serves as a layer between your HTML form and the action. So, all your action has to do, is to inspect the attributes of the FormBean to get to the data the user entered in the HTML form. The trick here is naming of html tags as you already figured out. I don't know what others on this list do, but as a rule of thumb I always use the constellation: JSP-FormBean-Action When polulating the jsp, you can also use the very same FormBean, to set up defaults, fill lists, whatever. It works in both directions.

Re: Validate() vs JavaScript where is the advantage?
Hi! JavaScript is one more technology added to the HTTP world. This protocol was origannly designed to transmit formatted data, so Javascript is fully optional. There is only one methos to check the validity of data, by means of server validation (struts or not). Javascript validation helps because errors were detected in cliente side, so implies lower network's data transmition. However, Javascript is optional (could be disabled, or not implemente by the browser) and have browser dependence.

RE: Validate() vs JavaScript where is the advantage?
While absolutely agree with the premise that you shouldn't trust what the client sends you, I think this reponse is a little too rigid. You need to take into account the environment your working in. If your talking about a situation where your clients are captive (i.e., an internal-only application where you know the browser type coming in), you can do some things that you can't do on a public-facing site. I've built a number of apps here at work that are exceptional in the sense that many people think they are using a fat-client because of the functionality and speed they see. I could only have accomplished many of the things I have in those cases because we're an IE-only shop with virtually no chance of ever switching (I've been told this from higher-ups, so it's not my problem if they change their minds). Some of the things that makes these apps unusual is because of all the client-side scripting that is done and all the dynamic HTML tricks I play. It allows you to have a webapp that doesn't REACT like a webapp because you avoid a lot of the round-trips to the server for things that could be done on the client, and you can have functionality you couldn't do otherwise (like instantaneous sorting of a table without touching the server for instance). I'm the first to admit you have to be careful in situations like this because it's easy to cause yourself trouble if you don't do it right. And of course if they ever do decide to change browsers we're going to have problems. But this is a decision that I don't think is as clear-cut as some are saying here (unless as I said it's a public site, then yes, I think it IS clear-cut: do it all on the server!) -- Frank W.

RE: Validate() vs JavaScript where is the advantage?
In limited, very controlled environments, I can see the advantages of client-side validation, but even then I would still validate server side because all it takes is one disgruntled employee and all of a sudden your nice controlled environment is blown apart. The only way you can guarantee a secure application is to trust nothing and no one. While I understand the pragmatic nature of the controlled environment (and believe me, I've developed applications with similar assumptions), the fact remains that trusting that the client cannot possibly deliver bad or malicious data is a security breach waiting to happen.

It allows you to have a webapp that doesn't REACT like a webapp because you avoid a lot of the round-trips to the server for things that could be done on the client, and you can have functionality you couldn't do otherwise (like instantaneous sorting of a table without touching the server for instance). I'm the first to admit you have to be careful in situations like this because it's easy to cause yourself trouble if you don't do it right. And of course if they ever do decide to change browsers we're going to have problems. But this is a decision that I don't think is as clear-cut as some are saying here (unless as I said it's a public site, then yes, I think it IS clear-cut: do it all on the server!) -- Frank W.

Thanks NK In short, you don't have control over your users' environment. They could be running old browsers; they could have JavaScript disabled; they could be running a browser with non-standard JavaScript support; their browser could be buggy. Malicious users could even manually assemble HTTP requests with invalid data. By using server-side validation, you take control over all of the data coming into your web application. If you leave validation to the browser, there is always the chance that bad data is going to sneak into your system and do something that you don't expect. -- Jeff - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To

I set the parameter up in the previous action with:

RE: Validate() vs JavaScript where is the advantage?

Help! Iterating through nested hashmap and setting properties
Hi all I have a problem with setting the values on a hierarchy of nested properties. I have an ActionForm which has a property A of type HashMap. A is keyed on Strings, and each value of A is a Collection (ArrayList). This collection contains objects of type B.

Is it possible to iterate through a HashMap, and let the user update its values? I am quite new to Struts, and urgently need this to work, but no luck. Any help will be really appreciated!

Visual editors for JSP's with Struts tags
Folks, My graphic designer is having difficulties with the design view in DreamWeaver looking at JSp's with struts tags. We have the fwasi struts tag plugs-ins for DW. Basically it seems DW design view support for JSP/Struts is rudimentary at best, and in our case mostly doesn't work. I think half the problem is that our JSPs use lots of @ include directives, and this seems to confuse DW (and indeed the visual view in JBuilder). Does anyone know of a Web development tool that has a good design view that supports JSP / Struts? TIA - Adam
RE: FW: R: Detecting the previous JSP
You shouldn't need to put the full path in, just setting the action to
deleteRegistration.do should be sufficient (assuming it's a root path, meaning not
something like /my/app/deleteRegistration. Not sure why it wouldn't work, looking
at my own code that's what I have (i.e., NOT the full path)

How to handle multiploe unknown form fields
I have an interesting situation, one that has never come up before, and I'm unsure how to deal with it... Imagine you have some records from a database representing various skills (i.e., HTML, Javascript, J2EE, etc.). Each has a SkillID associated with it. You create a JSP that lists each skill with a drop-down next to it. The drop-down allows the user to select their skill level for each skill. When the user hits Save, you need to update all the skills for that user. That's the scenario. Here's the question... Each drop-down is given the name of the SkllID. But how do you write an ActionForm for that? Since the database can be expanded to include new skills at any time, it's impractical to add getters and setters for each SkillID, and in fact breaks low coupling goals anyway. Is there a standard way of accepting what kind of amounts to an array of inputs from a form and getting it into an ActionForm in some way (maybe as an ArrayList or something?). TIA! Frank W.

Re: Reusing methods across actions classes
It may also depend on what kind of code you are trying to reuse. If its something that is action-related (populating a form, etc.) then I would agree with Danilo's answer. If on the other hand, the code is related to business logic that is really independent of the struts portion, then I would put this in a common class that can be reused from as many actions as need it. In a lot of my applications I use a facade for my actions to communicate with seperate objects relating to business logic. This also has the nice benefit of keeping your business logic independent of the particular web solution (in this case Struts) you are using. In fact, you can keep your business logic the same if you decide to write a client server app instead! sean Why don't you just create an abstract action and extend it?

RE: Reusing methods across actions classes
Writing your own Action class that extends Action and then extending that to make each class is an option. Depending on the nature of your shared code, it might be easier to just make an ActionHelpers class that contains a bunch of methods, maybe a bunch of static methods even, depending on what the code your trying to share actually is. I've done this in the past because I had some common code at the start and finish of each Action that had to execute (and there was a reason this worked while extending some class didn't, but I don't frankly remember the reason now). -- Frank W.

timeouts

RE: FW: R: Detecting the previous JSP
Well, certainly it it works, that's what counts :) But the path should be the path
that is in your struts-config file, the physical path shouldn't matter, i.e., if your
JSP in in the directory structure /my/app/jsp/part1, where /my is the root of the
webapp, and you submit a form to /some/bogus/path/delete.do, it should work fine as
long as that path your submitting to is valid in the config file. It's kind of a
virtual vs. physical thing (that confused me at first frankly).

Validator
Hi there! I've been using Struts for quite sometime, but haven't used
the validator yet.
So I followed the receipt provided by Struts in Action, but got no
success at all.
Here's what I've done
Struts-config is configured for the right plugin
My ActionForm extends ValidatorForm and has no validate() method
Validator-rules.xml:
validator name=required
classname=org.apache.struts.validator.FieldChecks
method=validateRequired
methodParams=java.lang.Object,
org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionMessages,
javax.servlet.http.HttpServletRequest
msg=validator.errors.required
javascript
![CDATA[
function validateRequired(form) {
var isValid = true;
var focusField = null;
var i = 0;
var fields = new Array();
oRequired = new required();
for (x in oRequired) {
var field = form[oRequired[x][0]];
if (field.type == 'text' ||
field.type == 'textarea' ||
field.type == 'file' ||
field.type == 'select-one' ||
field.type == 'radio' ||
field.type == 'password') {
var value = '';
// get field's value
if (field.type == select-one) {
var si = field.selectedIndex;
if (si = 0) {
value = field.options[si].value;
}
} else {
value = field.value;
}
if (trim(value).length == 0) { {
if (i == 0) {
focusField = field;
}
fields[i++] = oRequired[x][1];
isValid = false;
}
}
}
if (fields.length 0) {
focusField.focus();
alert(fields.join('\n'));
}
return isValid;
}
// Trim whitespace from left and right sides of s.
function trim(s) {
return s.replace( /^\s*/, ).replace( /\s*$/, );
}
]]
/javascript
/validator
validation.xml:
form name=userForm
field property=nome depends=required
msg name=obrigatorio key=validator.errors.required/
arg0 key=prompt.nome/
/field /form
ApplicationResources.properties
validator.errors.required= O campo {0} é obrigatório
prompt.nome=nome
And my jsp file looks like this:
html:form action=/atualizaDadosUsuarioAction name=userForm
type=br.com.auge.errors.action.form.UserForm onsubmit=return
validateRequired(this)
Nome html:text property=nome name=userForm/html:texthtml:errors
/br
/html:form
html:javascript formName=userForm/
Well, what is happening is that after I submit with no values at all,
nothing happens, it forwards to the
correct path. And also, the javascript generated isn't inside a
script/script block. So it's printed
on the page footer.
Where did I miss?
Thanks

Re: How to handle multiploe unknown form fields
You simply need a property in your ActionForm that returns a collection of skill beans and used the indexed attribute on the html tags.

RE: Validator
Hi Vinicius,
An easy question, have you put the right attribute in the
struts-config.xml in the actionMapping ?
You need to put the xml attribute validate=true and an input for the page
you want to return if the validation throw an error. An exemple :
action path=/createMPFromCollection
type=plateinv.actions.plate.MPCreateAction
name=mpCollectionForm
parameter=method
validate=true
input=tiles.plate.master.create.option
forward name=createMP
path=tiles.plate.master.create.confirmationMP/
/action

Hi there! I've been using Struts for quite sometime, but haven't used
the validator yet.
So I followed the receipt provided by Struts in Action, but got no

Here's what I've done
Struts-config is configured for the right plugin
My ActionForm extends ValidatorForm and has no validate() method

var isValid = true;
var focusField = null;
var i = 0;
var fields = new Array();
oRequired = new required();
for (x in oRequired) {
var field = form[oRequired[x][0]];
if (field.type == 'text' ||
field.type == 'textarea' ||
field.type == 'file' ||
field.type == 'select-one' ||
field.type == 'radio' ||
field.type == 'password') {
var value = '';
// get field's value
if (field.type == select-one) {
var si = field.selectedIndex;
if (si = 0) {
value = field.options[si].value;
}
} else {
value = field.value;
}
if (trim(value).length == 0) { {
if (i == 0) {
focusField = field;
}
fields[i++] = oRequired[x][1];
isValid = false;
}
}
}
if (fields.length 0) {
focusField.focus();
alert(fields.join('\n'));
}
return isValid;
}
// Trim whitespace from left and right sides of s.
function trim(s) {
return s.replace( /^\s*/, ).replace( /\s*$/, );
}
]]

And my jsp file looks like this:
html:form action=/atualizaDadosUsuarioAction name=userForm

validateRequired(this)
Nome html:text property=nome name=userForm/html:texthtml:errors
/br
/html:form
html:javascript formName=userForm/
Well, what is happening is that after I submit with no values at all,
nothing happens, it forwards to the
correct path. And also, the javascript generated isn't inside a
script/script block. So it's printed
on the page footer.
Where did I miss?

Using WildCards
Hi! I'm having some troubles using WildCards. I have
a Action declaration like this:
action path=/*OperationAction
type=alecio.presentation.web.action.{1}OperationAction
name=OperationForm
validate=true
scope=request
input={1}HomePage
parameter=operation
className=alecio.tech.presentation.web.struts.OperationActionMapping
!-- initial properties --
set-property property=structureName
value=structure{1}Model/
!-- forwards --
forward name=createPage path={1}CreatePage/
forward name=editPage path={1}EditPage /
/action
The WildCard for this declaration works fine with all
the items, except the one which is into the
set-property:
set-property property=structureName
value=structure{1}Model/
It doesn't replace the flag. How can i do such a
thing?
thanks!

Unfortunately, set-property is processed at config parsing time,
rather than runtime, so it is not possible to use wildcard replacement
in it.

RE: Struts and Quartz Scheduler
Starting Quartz from a servlet is not a good idea, use a Plugin instead.
Reason:
I am running on the JBoss application server, and the threads that Quartz
creates on startup are attached to the app server when using the servlet
method. Everything works fine, but when your webapp is shutdown, the threads
keep going. The threads do not stop until the app server is stopped. So, if
you do a hot deploy (just replace the .ear) of your application, which I do
quite often during development, you'll end up with multiples of your jobs
executing at the same time.
Using plugin:
If you use a Struts plugin, the threads stop when the webapp stops, even
when doing hot deploys. In the plugin, the init() method gets called once
when Struts starts up and the destroy() method gets called once when Struts
shuts down.
In my code below, I am called jobs implemented as stateless session beans.
Your jobs might be implemented differently.
Code:
Web.xml:
Nothing here because you are not using a servlet
Struts-config.xml:
Add this line:
plug-in className=com.mycompany.myapp.QuartzPlugin /

try {
sched = StdSchedulerFactory.getDefaultScheduler();
sched.start();
} catch (Exception e) {
log.info(Quartz Scheduler failed to initialize: + e.toString());
throw new ServletException(e);
}
log.info(Initializing jobs...);
addJob(sched, Heartbeat, HeartbeatJob, execute, 0 0/15 * * * ?);
// every 15 minutes
addJob(sched, ExpiredTrial, ExpiredTrialJob, execute, 0 0 20/24 *

log.debug(Quartz started);
}
private void addJob(Scheduler sched, String jobName, String jndiName,
String methodName, String timing) {
JobDetail jd = new JobDetail(jobName, ECOM_GROUP, EJBInvokerJob.class);
jd.getJobDataMap().put(EJBInvokerJob.EJB_JNDI_NAME_KEY, jndiName);

Object[] jdArgs = new Object[0];
jd.getJobDataMap().put(args, jdArgs);

Page refresh results in multiple calls to form bean?
I have a templated page. In a detail display section (in Detail.jsp), after an update, I forward back to the main page (call it Master.jsp). I also have a search section (Search.jsp) on the page. I put a log statement in a getter on the Form Bean behind Search.jsp. I notice that when I do something to kick off an update of Detail.jsp and it forwards back to Master.jsp, the getter in SearchForm gets called not just once (which I would expect) but three or four times. Is there some switch I should be setting to avoid this? Is it normal, but not a significant performance hit anyway? Thanks. T. McCobb
validator for radio button does not work
the client side validator for radio button does not work for required validation. The validation rules check for field.type==radio, but the field.type is 'undefined' when I tried an alert. But field[0].type returned radio. The validation_rules.xml has field.type==radio check all over. Has anyone successfully used this. Since radio buttons usually have one selected as default, this validation may be overlooked. But my requirement specifies not to have a default for the radio, but a validation that it is required. Please let me know if I'm missing anything. Jayaraman - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Do you have an error in server console when you validate ? I already had a

never had any of the problems you mentioned with my app and I do WAR HOT

Error Message for Struts Validation
I use the validation.xml to validate the properties in my form bean. The validation works; but, the error messages do not work as I expected. While I have customized error messages prepared, the error message displayed in the browser window for my intentional violation are like: . null is required . null is required I also wonder how to show error messages if there are more than one validation check for a certain property. For example, depends=required,mask. For example, in my validation.xml, I have: [CODE] form name=editTitleForm field property=document depends=required msg key=request.page/ /field field property=title depends=required msg key=insert.title/ /field /form [/CODE] In my web.xml, I have: [CODE] init-param param-nameapplication/param-name param-valueresources.application/param-value /init-param [/CODE] and the application.properties file is in the C:\jakarta-tomcat-5.0.27\webapps\AppName\WEB-INF\classes\resources directory.

Starting Quartz from a servlet is not a good idea, use a Plugin instead.
Reason:
I am running on the JBoss application server, and the threads that Quartz
creates on startup are attached to the app server when using the servlet
method. Everything works fine, but when your webapp is shutdown, the threads
keep going. The threads do not stop until the app server is stopped. So, if
you do a hot deploy (just replace the .ear) of your application, which I do
quite often during development, you'll end up with multiples of your jobs
executing at the same time.
Using plugin:
If you use a Struts plugin, the threads stop when the webapp stops, even
when doing hot deploys. In the plugin, the init() method gets called once
when Struts starts up and the destroy() method gets called once when Struts
shuts down.
In my code below, I am called jobs implemented as stateless session beans.
Your jobs might be implemented differently.

RE: RE: Struts and Quartz Scheduler
If you've not had any problems, that is good. Tomcat is probably taking care
of the threads for you and stopping them. Using the plugin is still better
because instead of relying on the app server to do your cleanup, you can
take charge of it yourself.

Hmm
never had any of the problems you mentioned with my app and I do WAR HOT
reload quite often. I never experienced the behaviour you mentioned on my

But since you mentioned it I will change it in my app too, so it is

RE: How to handle multiploe unknown form fields
I didn't realize that Struts could actually pass a pre-filled ArrayList.
That's pretty cool.The way that I've done index properties in Struts
call this method in my version:
Myproperty(int index, String value);
In that method, you can recreate whatever you want however you prefer.
This is a good reference for you to use --
http://struts.apache.org/faqs/indexedprops.html
You also can use regular struts html tags to create the indexed values
for you by using the indexed=true property instead of hand-writing out
the name values as in the example below. I use indexed properties to
recreate lists as well as objects in lists by tricking struts into doing
the right thing so the below will work. It may just be that I have not
explained it clearly if it doesn't work for you.
Hope it helps you.

Subject: Re: How to handle multiploe unknown form fields
In fact it did help because it answered some question for me. I spent
the last hour searching for the RIGHT answer... This looked like it, but
for whatever reason it would never work for me when I tried to do the
exact same thing in my own project. So, I went ahead and hacked
together my own solution...
In my test JSP, I have the following:
form name=test method=post action=test.mtx
input type=text name=skills[0] value=val0
input type=text name=skills[1] value=val1
input type=text name=skills[2] value=val2
input type=submit name=submit value=submit
/form
Then in my ActionForm, I have:
private ArrayList skills = new ArrayList();
public ArrayList getSkills() {
this.skills.add(new String());
return this.skills;
}
public void setSkills(ArrayList skills) {
this.skills = skills;
}
public ArrayList getSkillsClean() {
for (Iterator it = this.skills.iterator(); it.hasNext();) {
String s = (String)it.next();
if (s.trim().equalsIgnoreCase()) {
it.remove();
}
}
return this.skills;
}
Struts knows that it's an indexed property and knows how to populate the
ActionForm. The problem I found is that you either have to (a) have an
initial capacity for the ArrayList and more importantly you must
initialize all the elements because the getSkills() method is called for
each element that is added. So, instead, I add an element in
getSkills() myself. The problem is, if you then later call getSkills()
from the Action, as one would expect to do, you'll always have an empty
element at the end (or more, if you happen to call the method more than
once). No big deal, but I decided I didn't like it, so I added the
getSkillsClean() method, which removes the empty elements.
I don't think I'm doing this the right way, and indeed the link you sent
shows a more elegant solution, but as I said it wouldn't work for me
when I tried, and I like things that work (I'm odd that way!), and this
has that virtue, so I'm happy.

I understand the JSP side of this eqation as you wrote it, although I
should have said I was looking for a solution that doesn't use Struts
taglibs because I try to avoid them at all costs, but that aside...
I'm still unclear however on what the ActionForm does... Using this
concept, do I HAVE to use the LazyActionForm you wrote? I'd prefer to
only
use things that are built-in to Struts, and unless I'm missing it in
the
docs, that's not.
The question I'm getting at is that, like I said, the JSP code you
wrote
makes sense, but what will put the submitted parameters into the
collection
in the ActionForm when the submission happens? That's the part I
don't
see. Thanks for your help!

Re: Deploying struts
Hi there, you should put it in the WEB-INF/lib directory. However the struts-documentation should run straight out of the box. I suspect you have a configuration failure somewhere.

Re: Setting values of nested collection
Hi Danielle, are you sure you instantiated the appropriate hierarchy for struts to save the form properties into on submit? You can build it yourself, keep it in the session or use LazyBeans (not sure about the last one - might be called LazyNested or similar). Adam On 09/30/2004 07:33 AM Danielle Boukovska wrote: Hi all I have a problem with setting the values on a hierarchy of nested properties. I have an ActionForm which has a property A of type HashMap.

Is it possible to iterate through a HashMap, and let the user update its values? I am quite new to Struts, and have spent a lot of time trying to get this to work, but no luck.

Re: [NEWBIE] Local forward with html:link?
You can take 2 approaches. You can split the page into tiles, one tile contains the form input elements and is nested inside the other tile which contains the form and the buttons. Then you re-use the first tile and swop the second tile depending on your mapping. Alternatively you can have a dispatch action. This would be the action of the submit, and it would direct execution within struts to your desired method within your action. HTH Adam On 09/29/2004 04:02 PM fjalvingh wrote: I have no issue with the action: it indeed has no knowledge about the actual views being used which is OK. It means I'm able to re-use actions if I want to. The JSP pages however seem to know way to much about navigation. They know this because they directly refer to an action path. This seems to make it impossible to re-use the same JSP page in a different context. As an example take a JSP page that is used to display a product. I should be able to use this page from a flow where all products are shown, and from a flow where products are searched, and from a flow where products are edited. The JSP page has a number of predefined exits like previous, next, edit, back. The presentations for these exits should be visible only for contexts where they have meaning (where they are mapped to some action). To make this page reusable I need to be able to connect each exit to a different action depending on the context that the page is used in. I would have expected that I could wire these entries using the action spec the page returns to. As I now start to understand this is possible but by hand- by making a special controller OR a new base class for Actions which uses a parameter to dispatch to a specified forward. But I still need to hard connect a JSP page to a controller as the target and this makes re-use of the page hardly possible. Am I right in this? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Forms and Building Generic logic to control focus
Example of retrieving the configuration of the form.
OutStanding questions are:
1.) Is the order of the array returned from findFormPropertyConfigs()
call the order defined in the form-property tag of the
struts-config.xml file?
2.) From the server side. If one wished to determined if the fieldname
was required. What would one do to determine this? So that one might
call formBean.setFocus(fieldName) from the action class.
// code taken from DynaActionFormClass
DynaActionForm formBean = (DynaActionForm) form;
FormBeanConfig config =
ModuleUtils.getInstance().getModuleConfig(request).findFormBeanConfig(m
yFormName);
FormPropertyConfig props[] = config.findFormPropertyConfigs();
for (int i = 0; i props.length; i++) {
if (fieldName.equals(props[i].getName())) {
formBean.set(props[i].getName(), props[i].initial());
break;
}
}
Any help would be appreciated.
Thanks
Re: Error Message for Struts Validation
I've never used the msg attribute myself, but I think when you do, you
need to specify the key, and a name attribute for which validation the
message applies to. So in your case it would be:
msg name=required key=request.page /
You may also need to specify a bundle and resource attribute, but I
don't think so in your case.
The error message you are seeing (null is required) is from the default
error message. When you use the default error message, you need to
specify replacement values for the error message template. If you look
in your application.properties, you should have a bunch of errors.
lines, for each standard validator. For example, you should have a line
like:
errors.required={0} is required.
for the required validator. The {0} is what needs a replacement. To
define it in your validator, you use:
arg0 key=request.page /
OR (for struts 1.2.x)
arg key=requst.page position=0 /
In these cases though, request.page should be defined in
application.properties as:
request.page=Page
then, when the error prints, it will print as Page is required.
For me at least, this is a lot more handy than using msg, because you
can use the same label to print out the prompt and the error message.
Hopefully I explained this well enough...

While I have customized error messages prepared, the

. null is required
. null is required
I also wonder how to show error messages if there are
more than one validation check for a certain property.
For example, depends=required,mask.
For example, in my validation.xml, I have:
[CODE]
form name=editTitleForm
field
property=document
depends=required
msg key=request.page/
/field
field
property=title
depends=required
msg key=insert.title/
/field
/form

In my web.xml, I have:
[CODE]

param-valueresources.application/param-value
/init-param
[/CODE]
and the application.properties file is in the
C:\jakarta-tomcat-5.0.27\webapps\AppName\WEB-INF\classes\resources
directory.
In the application.properties, I have:
[CODE]
request.page=The requested page is not provided.
insert.tile=The title of the requested page must not
be left blank.
[/CODE]

Re: How to handle multiploe unknown form fields
Rather than answer you here, I've set up a wiki page showing three different options for lazy list type behaviour http://wiki.apache.org/struts/StrutsCatalogLazyList I understand you wanting to only use released stuff - actually if you look at LazyValidatorForm, theres not much too it - most of what it uses is either already in Struts (it extends BeanValidatorForm) and Commons BeanUtils (LazyDynaBean) - creating your own lazy ActionForm wouldn't take much. In fact you can even use a LazyDynaBean directly in the struts-config.xml as your ActionForm in Struts 1.2.4 Niall - Original Message - From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, September 30, 2004 6:54 PM Subject: Re: How to handle multiploe unknown form fields I understand the JSP side of this eqation as you wrote it, although I should have said I was looking for a solution that doesn't use Struts taglibs because I try to avoid them at all costs, but that aside... I'm still unclear however on what the ActionForm does... Using this concept, do I HAVE to use the LazyActionForm you wrote? I'd prefer to only use things that are built-in to Struts, and unless I'm missing it in the docs, that's not. The question I'm getting at is that, like I said, the JSP code you wrote makes sense, but what will put the submitted parameters into the collection in the ActionForm when the submission happens?

Imagine you have some records from a database representing various skills (i.e., HTML, Javascript, J2EE, etc.). Each has a SkillID associated with it. You create a JSP that lists each skill with a drop-down next to it. The drop-down allows the user to select their skill level for each skill. When the user hits Save, you need to update all the skills for that user. That's the scenario. Here's the question... Each drop-down is given the name of the SkllID. But how do you write an ActionForm for that? Since the database can be expanded to include new skills at any time, it's impractical to add getters and setters for each SkillID, and in fact breaks low coupling goals anyway. Is there a standard way of accepting what kind of amounts to an array of inputs from a form and getting it into an ActionForm in some way (maybe as an ArrayList or something?).
