RE: Using JSTL Instead of Nested Tags
Mike, you will have to expose the form like:
c:set var=form value=${myForm}/
...where myForm is its name defined in the struts-config file.
If its DynaForm then you have to expose the form map:
c:set var=form value=${myForm.map}/
Once you do this, you can use JSTL to access and render values:
c:out value=${form.someProperty}/
or
c:out value=${form.some.nestedProperty}/

Subject: Using JSTL Instead of Nested Tags
I'm trying to convert an application from Struts display tags to JSTL (still using
Struts as the

I am having some difficulty converting nested tags to JSTL.
Can anyone offer any guidance?

RE: user login authentication and session timeout
Charles, you can use container managed security or the SecurityFilter to authenticate users when accessing protected resources. You can set the session time out by adding something like the following to your web.xml file: session-config session-timeout60/session-timeout /session-config You can find more information on SecurityFilter here: http://sourceforge.net/projects/securityfilter/ Your servlet container documentation should let you know how to implement container managed security. robert -Original Message- From: Charles Jordan [mailto:[EMAIL PROTECTED] Sent: Monday, March 22, 2004 1:35 PM To: [EMAIL PROTECTED] Subject: user login authentication and session timeout I'm looking for examples or to be pointed in the right direction on how to achieve the following.

RE: Bean:write
Try using the following with JSTL:
c:set var=myValue value=${teacher.SSN}/
or you can try the following using bean:*.../
bean:define id=myValue name=teacher property=SSN/
If you are still getting a error make sure you are
using proper JavaBean naming conventions. You can find this in
the JavaBean specification.

RE: action - delegate - facade
Adam, I think Nick was just asking about the trip from the server to the client, not from the client to the server. As already discussed, the method for transfering user input to the business tier would be to copy the values from the action form to the appropriate DTO's using BeanUtils or some other method. robert -Original Message- From: Adam Hardy [mailto:[EMAIL PROTECTED] Sent: Thursday, March 18, 2004 4:57 AM To: Struts Users Mailing List Subject: Re: action - delegate - facade Downside is though, trying to cram string request parameters into your DTO in your form before you validate them. Causes ugly exception messages on the browser. On 03/18/2004 02:25 AM Robert Taylor wrote: Well, I would say it depends. If I had a DTO ( a domain object) which had all the fields I needed to display...including types like int, Date, boolean, etc... I would probably just pass that along to the form bean and let view helpers like the Struts tags or JSTL render the contents. With JSTL you can format Dates and numbers. I believe those tags leverage the java.text.* package for formatting data. If I needed to perform some specialized formatting which could not be done by view helpers then I may just convert the necessary fields to Strings (maybe using BeanUtils) format them, and populate my ActionForm. If the view I needed of the data was not encapsulated in a single DTO, then you could retrieve multiple DTO objects and rendered them as described above or use a pattern described as Transfer Object Assembler which builds a custom DTO or a collection of customer DTO objects which you could pass along to the ActionForm.

Subject: Links within ActionErrors
I know this probably violates some basic guidlines but...
I am trying to display an html link rendered by the message in the
ActionErrors section of a JSP.
My problem is that the '' and '' symbols are being replaced by ' l t;'
and ' # 034;' (their equivelent)
How can I prevent this translation from happening?
Example:
In the applicationresources file we have something like the following:
error.save.dup.link=a href={0}click for details/a
The action class creates the actual link address and adds an actionError as
follows:
tActionErrors.add(ActionErrors.GLOBAL_ERROR,
new ActionError(error.save.dup.link,
iRequest.getRequestURL().substring(0,iRequest.getRequestURL().lastIndexOf(/
)) +
/blah blah blah ));
saveErrors(iRequest, tActionErrors);
In the JSP we have tags to dislay the errors:
logic:messagesPresent
tabletrtd
bspan id=errorsHeaderbean:message
key=errors.validation.header//span/b
html:messages id=error
c:out value=${error}/
/html:messages
/td/tr/table
/logic:messagesPresent
When the error is displayed because the '' and '' signs have been replaced
it just show the text as follows:
a href=http://localhost:8080/blah blah blah click to see /a

RE: action - delegate - facade
by xdoclet? I've been using an xml schema to generate my value objects so far (not with EJB) via JAXB, but this isn't going to work with EJB because the things aren't serializable. Another question (my last!): what is the best way to handle home interfaces in the delegate? Do you cache them? Do you treat them like a logger object or a singleton? Or do you just instantiate them fresh each call? Thanks! Adam On 03/17/2004 09:22 AM HG wrote: Hi Robert and Adam... Guess I am paranoid or prepared.. :-) I use nearly the approach Robert described, using a Factory for the delegatealthough the purpose is not the same.. I use the Delegate as the web tier view of the business logic/services in the system. That becomes important, when different business rules/logic applies to different modules/plugin. In my scenario I call the business delegates for business plugins because of the dynamic plugable nature. Plugins are hosted by a plugin manager (the factory), and access the plugin interfaces always goes through the plugin manager. You get an interface to a plugin (ie. web tier view of a business service), not an implementation...that's important as you state correctly Robert. The difference is that I don't care if it is a POJO, EJB, whatever I am talking to behing the scenes, I care about HOW the business service is implemented... Let me give you an example: Way through system is: Action-Plugin-Facade-Entity Pseudo code for action execute: AccountManagement plugin = pluginManager.getPlugin(core.account.management); What I get here is an interface (AccountManagement) of a business service plugin. Behind the interface, one specific implementation of it resides. WHAT implementation to use is decided by the plugin manager. I my scenario it is based on a customer, which have a certain business role. But it can be whatever logic to decide which implementation to use. Now I use the the plugin business service interface from my action plugin.createAccount(001, Hans Gruber); With this one call a specific implementation of the Management interface is called. What happens behind the scenes is not important from the actions point of view. Maybe different business rules/logic applies for different implementations of the AccountManagement. What actually happens is that the plugin service implementation calls a facade to fulfil the business action of creating an account. This approach is highly flexible...You have the possibility of hosting different customers (with different needs) under the same application constrcuted using business plugins building blocks. It also (like other business delegates as you stated Robert) promotes loosely coupling between the web tier and EJB or whatever tier is behind. With this clean interface it is very very easy to provide an additonal XML WebServices interface (maybe though Axis) that makes your business services accessible from other platforms, systems, whatever...

RE: action - delegate - facade
Well, I would say it depends. If I had a DTO ( a domain object) which had all the fields I needed to display...including types like int, Date, boolean, etc... I would probably just pass that along to the form bean and let view helpers like the Struts tags or JSTL render the contents. With JSTL you can format Dates and numbers. I believe those tags leverage the java.text.* package for formatting data. If I needed to perform some specialized formatting which could not be done by view helpers then I may just convert the necessary fields to Strings (maybe using BeanUtils) format them, and populate my ActionForm. If the view I needed of the data was not encapsulated in a single DTO, then you could retrieve multiple DTO objects and rendered them as described above or use a pattern described as Transfer Object Assembler which builds a custom DTO or a collection of customer DTO objects which you could pass along to the ActionForm.

RE: can anyone help me address this issue
You can't send data structures over HTTP you can only send strings.
You could set those values as hidden form elements with a naming
convention that would enable your server side code to recognize
the elements in the request and create the appropriate server side
data structure. This is essentially what Chris has suggested.

use onResize on the html element that is clicked to report its new value
to a form variable. use an onChange for the form to auto submit itself. If
you need to hide the submission of the form use an IFrame.

I m using javascript doing dhtml, now I have a table, every time
a user changes the width of a specific column(by draging the border
line), I will save the column index and the new width to variables
in javascript.Now ,after doing many such changes, I need to submit
those values saved in the vairables to the server side program by
submiting a form, which has an action path designing what action
should be called after it get the submitted value. Now, I m
wondering how I should define such javasript variables and how I can
submit these values by submiting a form? I m using struts, is there
any possibility to implement this idea in struts?

RE: [OT] Database locking and deadlock
Is it possible that dbConnection.doUpdate() gets a new connection
each time which could possibly use up (exceed max allowed) the connections in the pool.
Just a guess.

Subject: [OT] Database locking and deadlock
Hi,
I know the subject of my mail is off-topic but I hope
somebody will be able to help me out with my problem.
I experienced a wierd problem today when a deadlock
occured in my database - Oracle 9i, and it locked up
all connections in the connection pool on my server -
OC4J (Oracle 9iAS). I have a connection pool, which is
configured on my server- OC4J. It is intialized on
server startup, using a Servlet.
I would like to verify if the code I use in my DAO may
cause any deadlock condition. In my DAO, I use
Update queries as part of a transaction. i.e, I turn
off auto-commit, do my Update queries, and commit or
rollback depending on the outcome of the queries.
In one of the queries, I may need to update multiple
rows of a table, and hence do the update operation in
a loop (over a collection).
Given below is the relevant portion of the code:
snip
//method that updates votes for candidates in an
election
public int updateVotes(BallotList ballotList)
{
int result=0; //result of insert operation
String query=;
Ballot ballot=null;
CandidateList candList=null;
Candidate candidate=null;
int currVote=0;
int electionNo = ballotList.getElectionNo();
try
{
for(int i=0;iballotList.getSize();i++)
{
ballot = ballotList.getBallot(i);
candList = ballot.getCandidateList();
for(int j=0;jcandList.getSize();j++)
{
candidate = candList.getCandidate(j);
//update votes for candidate
if(candidate.getVote() 0)
{
//get current vote count and update
currVote =
getCurrentVote(electionNo,candidate.getPostNo(),candidate.getPidm());
currVote++;
query = Update DZRCAND set DZRCAND_NUM_VOTE =
+currVote+ +
where DZRCAND_ELCTN_NO =
+electionNo+ +
and DZRCAND_POST_NO =
+candidate.getPostNo()+ +
and DZRCAND_CAND_PIDM =
+candidate.getPidm()+;
result += dbConnection.doUpdate(query);
}
} //end of inner for loop
} //end of outer for loop
}
catch(Exception e)
{
System.out.println(Exception in DZRCAND
update for votes: + e.getMessage());
System.out.println(query: + query);
}
return result;
}
/snip
Is there a possibilty of a deadlock occuring in the
above code when there are mutliple users concurrently
accessing the system.i.e, multiple users update
multiple rows of the table at the same time
Could somebody throw some light on this?
My understanding is that deadlocks are automatically
handled by the DBMS. Anyway, is there a way to prevent
the possiblity of deadlocks in my program ?
One more thing - in the code above and in other
Select queries, I open and close the Connection from
the connection pool. However, I do not close the
Statement or ResultSet objects. Will this lead to
problems ? My understanding is that closing the
Connection object will free up all the associated
resources.
Any help/pointers/suggestions will be greatly
appreciated.
Thanks,
Shyam

Thanks for the explanatory smaples.The syntax below seems JSTL

Any quick intro I read on JSTL...
Thanks
Henri Yandell [EMAIL PROTECTED] wrote:
Just to show how easy it can be with beanutils:
display_categories.do points to a struts action that preloads like:
*
List list = new ArrayList();
list.addAll( DummyDao.getAllCategories() );
String sortBy = request.getParameter(sortBy);
if(sortBy != null) {
BeanComparator comparator = new BeanComparator(sortBy);
Collections.sort( list, comparator );
}
request.setAttribute( categories, list );
return mapping.findForward(success);
*
and the jsp page that success points to contains:
name
description
where Category has 'name' and 'description' as properties. This handles
things with natural sorting. Doing the reverse sort used to be pretty
easy, but is harder now that we separate the view and model [as the model
wants to record view-state, or maybe the view wants to record model-view
state...ugh].
The trick is by having:
if(reverse) {
comparator = new ReverseComparator(comparator);
}
after the BeanComparator line. The only complication is where you decide
to store reverse. You can use the session, or as you'll probably want
little arrows showing the sort direction, you can write it into the
column-header with '?sortBy=namereverse=true'. This can be tricky and
probably involves the Action storing things in the request scope for the
jsp to discover later.
Anyway, I assume the display-tag library contains this pretty much, but
Comparators are lovely so it can't hurt to babble on about them :)

I do it on the server side, holding the items to be sorted in a Map and

new order. Then when you're back on the JSP iterating over it, the
items are in the correct order.
Map accountMap = (Map) session.getAttribute( accountMap );
Map newMap = new TreeMap( new CostCenterComparator() );
newMap.putAll( accountMap );
session.setAttribute( accountMap, newMap );

works...]

RE: Validation help for same Form, multiple pages/tabs
Are you using DispatchAction or LookupDispatchAction? robert -Original Message- From: Wendy Smoak [mailto:[EMAIL PROTECTED] Sent: Friday, March 05, 2004 1:24 PM To: Struts Users Mailing List Subject: Validation help for same Form, multiple pages/tabs I'm using the same [dynamic] ActionForm on all my pages. Which was just *fine* until I wanted to use validation. :( I need separate validation per tab which is essentially a forward tag in struts-config.

Another tab has radio buttons where they pick an account. On the first, I need all three fields to be required.

I found this, advocating DynaValidatorActionForm http://www.mail-archive.com/[EMAIL PROTECTED]/msg93220.html But it seems to be controlled by the path, which is going to be the same in both cases. -- Wendy Smoak Application Systems Analyst, Sr. ASU IA Information Resources Management - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Validation help for same Form, multiple pages/tabs
Okay. Here is what I do which may or may not help.
I have subclassed DispatchAction to handle image buttons.
The newer Struts version may handle this, but it didn't prior
to 1.1. Image buttons may not be your problem but it has a special
method to extract the dispatched operation.
Anyhow you can see the implementation here.
http://issues.apache.org/bugzilla/show_bug.cgi?id=19925
I also subclass DynaValidatorActionForm which uses the static method defined
in ImageButtonDispatchAction to extract the operation parameter.
/**
* Validate the properties that have been set from this HTTP request,
* and return an codeActionErrors/code object that encapsulates any
* validation errors that have been found. If no errors are found, return
* codenull/code or an codeActionErrors/code object with no
* recorded error messages.
*
* @param mapping The mapping used to select this instance.
* @param request The servlet request we are processing.
* @return ActionErrors containing validation errors.
*/
public ActionErrors validate(ActionMapping mapping, HttpServletRequest request) {
// set the page variable before validating
Map props = this.getMap();
if (props.containsKey(page)) {
this.page = ((Integer) props.get(page)).intValue();
}
ServletContext application = getServlet().getServletContext();
ActionErrors errors = new ActionErrors();
String validationKey = this.getValidationKey(mapping, request);
logger.fine(validationKey: + validationKey);
Validator validator =
Resources.initValidator(
validationKey, this, application, request, errors, page);
logger.fine(validator: + validator.getClass().getName());
try {
validatorResults = validator.validate();
} catch (ValidatorException e) {
log.error(e.getMessage(), e);
}
return errors;
}
/**
* Get the validation key used to determine which validation
* rules will be executed.
*
* @return the validation key
*/
protected String getValidationKey(ActionMapping mapping, HttpServletRequest
request) {
String path = mapping.getPath();
String parameter = mapping.getParameter();
if (parameter == null) {
return path;
}
String operation = ImageButtonDispatchAction.getOperation(parameter,
request);
return MessageFormat.format(
VALIDATION_KEY_TEMPLATE, new Object[]{path,
operation});
}
This allows me to have validation keys of the form: path-operation.
So in my validation.xml I have form elements that look somewhat like:
form name=/applications/account/doSaveChanges-create
/form
form name=/applications/account/doSaveChanges-update
/form
As you can see, the same action mapping path is used but the operation
is appended to them allowing for more granular validations.
This may not be the best way to handle things, but I've been using
this approach for a couple years and it works quite well.

RE: DispatchAction and validate
Yes. The DispatchAction will only invoke the method defined in the request under the name defined in the parameter attribute of your action mapping. So if I had update() and restore() as methods in a DispatchAction, and I only wanted to validate on the update, then I would only define validate=true in the action mappping for the DispatchAction which is designated to invoke update(). This is assuming you have two separate action mappings which map to the same DispatchAction. robert -Original Message- From: Frers Michael [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 02, 2004 3:23 AM To: Struts Users Mailing List Subject: DispatchAction and validate Hello i want to use DispatchAction now my questions is can i use in one action the struts-config entry validate=true and in the other action validate=false Thx for any hints Michael - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Subject: servlet filters and authentication
Hello,
I'm configuring the skeleton of a multi module struts application, and i
would like use a filter for the authentication.
here is psuedojava (for easier reading) of the filter:
public final class AuthFilter implements Filter {
public void doFilter(request, response, chain)
session = request.getSession();
auth = session.getAttribute(authenticated);
if (auth == true) {
chain.doFilter(request, response);
return;
}
else {
dispatcher =
request.getRequestDispatcher(/WEB-INF/jsp/security/login.jsp);
dispatcher.forward (request, response);
return;
}
}
}
I've seen this skeleton suggested in several places on the web.
The question i have is this: After the user submits the login form,
the request will come through the filter, and since it has not yet
been authenticated, it will again forward to the login.jsp.
I've thought of a couple of ways to deal with this and
would like to get input on these and any other approaches.
1) set the mapping of the filter in web.xml in such a way that it
allows the login action through. maybe set all actions to have an
extension of .do except the login action, which has an extension of
.auth. I don't think this will work for me, because the multi module
support of Struts requires extension mapping. I guess i could write a
small serlvet that is not in the struts mapping but is in the same context
and have it mapped to *.auth
2) check within the above filter to see if the request is for the login
action, and if so allow it through. so the if statement above would be:
if (auth == true || req.getPath().equals(login.do))
Any comments on these ideas or approaches i haven't listed would be
greatly appreciated.

RE: Common Services across Different Actions.
Wrap the service in a ServletContextListener.

RE: [OT] Sending email from struts
Matt, we ended up storing our email templates in a configuration file and loading them into memory (using Digester) at application run time. The configuration templates can contain both plain text and HTML message versions. We leverage the java.text.MessageFormat API to replace place holders in the templates with actual data. In the application, we use a design pattern called EmailHelper. EmailHelper provides a business API to which the application passes information. For example, after a customer downloads a product, the application might do something like: EmailHelper.getInstance().sendThankYouMessage(user, product); where user and product are application data structures respectively representing the current user and the product which was just downloaded. Subsequently, EmailHelper mines the necessary data from the arguments and then performs lower level operations such as retrieving the appropriate email template from the in memory configurations, populating the template and then persisting the email to the appropriate queue where it will be delivered later. A different application (daemon) periodically retrieves unsent email from the queue and sends them using the JavaMail API. It has worked quite well so far. If we need to tweak the templates, we can do so and reload the configurations. You could take this idea a step further and store the templates in the database. This does seem like a common task in applications and it would be nice if there were some standard framework to use, but I don't know of any in development currently. robert -Original Message- From: Matt Bathje [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 11, 2004 11:03 AM To: strutslist Subject: [OT] Sending email from struts Hi all. This is kind of off topic as it is not really struts related, but somebody here would probably have the answer. We have our application sending emails to users at some points and it is working fine. The problem is that we have the email message hardcoded into the Java, which we would like to avoid either by storing the message in application.properties or our database. This would be easy, except all of the messages contain user-specific information like their name or phone number or order id or something like that. Anybody have any ideas (or links to programs!) that can read in an email, replace the information it needs to from the db, and send that to the user. I could obviously write something myself to do it, but wouldn't want to reinvent the wheel. Turns out this is hard to search for too - email is not a search term that makes things easy.

RE: global data objects -- best practices?
Yes, the ServletContext is the most appropriate place to put it if you want your data to be available during the life time of the application. If your container conforms to Servlet spec. 2.3 or higher, a solution is to implement one or more ServletContextListener(s). Is the a best practice? I think that may be subjective, but it does not bind you to any third party solutions. The container must invoke these upon application start up before it processes any requests. For more information refer to the Servlet 2.3 spec or higher. http://java.sun.com/aboutJava/communityprocess/first/jsr053/index.html robert -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 04, 2004 3:00 PM To: [EMAIL PROTECTED] Subject: global data objects -- best practices? hi, I have a question regarding data objects that should be accessible from the entire application and which must be created at container startup time. I need to either create and load an existing index or load a serialized index if one exists. This can be a time-consuming process, and I would like to do it once when the servlet container starts, then keep the index in memory thereafter and available to the entire web application. I've seen a few different ways of doing this by searching the archives, but there wasn't a definitive best practice solution that I came across, and the struts API has also changed since many of the suggestions were offered. At present, I am extending the ActionServlet and taking care of the initialization stuff in the subclass's init(). I place the generated index in the ServletContext. This ensures that the index creation will occur only once, at container startup, and that it will be available to the action classes of that web application, but I'm not sure if this is the best solution. Also, I have just come across plugins for the first time, and it seems that they also provide a way of doing application-specific initialization. Having the index creation code in the ActionServlet, as it is at present, seems messy to me, so perhaps that is not the best place for it. In short, what is the best method for ensuring that a global index is created exactly once, and at container startup time? At present, I am subclassing ActionServlet, and doing it there, but is the plugin mechanism an alternate (better?) solution? Is the ServletContext the appropriate place for global data? thanks in advance, n. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

But how can I get the value specified in the parameter attribute in my action class. ActionMapping.getParameter() will get you the value of the parameter attribute. Also using set-property inside a action tag does not work? It works for me. You have to subclass ActionMapping and declare it in your struts-config file. action-mappings type=com.companyname.SubclassedActionMapping So when you use set-property, Struts can set those values using reflection. My guess as to why its not working is that it silently fails to set those properties because they don't exist in the default ActionMapping class. robert -Original Message- From: Anand Patil [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 04, 2004 4:06 PM To: [EMAIL PROTECTED] Subject: Using Parameter in Action via the struts-config.xml Hi All, The struts configuration DTD supports having a parameter attribute to a action.

When the web application starts the ServletContextListener.contextInitialized() is invoked passing you ServletContextEvent which contains the ServletContext. These are guaranteed to be invoked before the web application can process any requests. It's simply an interface which you implement (2 methods) then define in your web.xml file. For more information refer to the Servlet 2.3 spec or higher. http://java.sun.com/aboutJava/communityprocess/first/jsr053/index.html robert -Original Message- From: Otávio Augusto [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 03, 2004 8:39 AM To: Struts Users Mailing List Subject: Re: [OT] looking for a method that will be called on application startup do you mean a single implementation of a servlet, with methods which fit each developer needs, and declaring this servlet in the appropriate place in the web.xml file? doesn't this servlet need anything special?

John, why not retrieve these from the DB at application start up time
and place them in the ServletContext where they are accessible for

RE: Validation problem
What's the name of your Cancel button? Struts should not validate
if it finds org.apache.struts.taglib.html.CANCEL or
org.apache.struts.taglib.html.CANCEL.x
Take a look at the RequestProcessor.processValidate() code:
if (request.getAttribute(Globals.CANCEL_KEY) != null) {
if (log.isDebugEnabled()) {
log.debug( Cancelled transaction, skipping validation);
}
return (true);
}
That attribute gets set in RequestProcessor.processPopulate():
// Set the cancellation request attribute if appropriate
if ((request.getParameter(Constants.CANCEL_PROPERTY) != null) ||
(request.getParameter(Constants.CANCEL_PROPERTY_X) != null)) {
request.setAttribute(Globals.CANCEL_KEY, Boolean.TRUE);

I am wondering how to solve the following problem with a minimal amount
of recoding, and hope someone can give some input. I have a form the
has three html:submit buttons -- Update, Cancel and Delete. I am
using a LookupDispatchAction and an ActionForm with the validation in
the validate() method. Under normal conditions everything works
fine..But when a user clicks Update with invalid data on the form,
the validate method catches the bad data and returns the proper error
message. If the user then decides to click Cancel (without changing
the invalid data), the validate() method is still called and the user
is returned the same error.
One thing that I might be able to do is to somehow find out what button
was clicked in the validate() method...?? How would I do that, I
wonder...
thanks in advance,

RE: Using ArrayList instead of String[] properties
Wendy,
If you simply want to present a list of options to the user represented as
check boxes
and collect the selected options, and the selected options are just single
string values,
then you can do the following:
Define accounts property as an java.lang.String[] and initialize it to {}.
form-property name=accounts
type=java.lang.String[] initial={}/
Retrieve you options and store them in an ArrayList named accountOptions
and render the options like so:
c:forEach var=account items=${accountOptions}
html:multibox property=accountsc:out
value=${account}//html:multibox
/c:forEach
This should generate HTML like:
input type=checkbox name=accounts value=someValue/
input type=checkbox name=accounts value=someValue2/
input type=checkbox name=accounts value=someValue3/
The servlet container will collect these values and place them in a single
String array under
the accounts name.
Struts will reset your form and them populate the accounts property of your
form with the String array.
Unless I've missed something, I don't see the need to using indexed
properties here if the selected value is single String and order doesn't
matter.

This works to generate HTML, but BeanUtils can't populate the ArrayList
that is the 'accounts' property of accountForm because the bracketed []
indexes are missing.
logic-el:iterate
collection=${accountMap[accountForm.map.calendarYear]}
id=acct
indexId=ctr
html-el:checkbox property=accounts

However, if I add indexed=true like so:
logic-el:iterate
collection=${accountMap[accountForm.map.calendarYear]} id=acct
indexId=ctr
html-el:checkbox property=accounts indexed=true
c:out value=${acct.key}/
/html-el:checkbox
It renders this HTML:
input type=checkbox
name=org.apache.struts.taglib.html.BEAN[0].accounts
value=on10_U_FADA0001
??! This is my first attempt at indexed properties, which apparently I
need in order to use an ArrayList. (The items in the ArrayList are just
Strings, not complex objects. This isn't nested properties, it's just a
bunch of checkboxes. I'm trying to use ArrayList instead of String[] to
avoid out of bounds errors. String[] was working *fine* last week,
until I got the bright idea to use ArrayList.)
I'm getting the feeling that the things in the ArrayList property of the
form have to be complex objects and not just Strings.

Thank you for your comment, which is very helpful.
Instead of extends ThreadBean, I now import the
ThreadBean into my ThreadHandler class (see the
code
below). I am still getting all null or zero values
from the bean.
What is the proper way to do it? I simply want to
insert the value of all the properties into the

require
NOT NULL.
code:

import org.apache.artimus.message.ThreadBean;

{
ThreadBean threadBean = new ThreadBean();
String receiver = threadBean.getReceiver();
String sender = threadBean.getSender();
String threadTopic = threadBean.getPostTopic();
String threadBody = threadBean.getPostBody();
Timestamp threadCreationDate =
threadBean.getThreadCreationDate();
int threadViewCount =
threadBean.getThreadViewCount();
int threadReplyCount =
threadBean.getThreadReplyCount();
MessageDAO md = new MySQLMessageDAO();
public int insertThread( ThreadBean threadBean
RE: All The Bean Properties Are Null in the Business Tier!!! (Used BeanUtils to Convert DynaValidatorForm)
Your code seems a bit confusing based upon what you want to
achieve.
If indeed you want ThreadHandler to inherit from ThreadBean,
you should be able to do something like this:
DynaActionForm postForm = ( DynaActionForm )form;
ThreadHander = new ThreadHandler();
BeanUtils.copyProperties( threadHandler, postForm );
threadHandler.insertThread();
The reason you are getting null and zero values in ThreadHandler
is that you are populating a new instance of ThreadBean here:
DynaActionForm postForm = ( DynaActionForm )form;
ThreadBean threadBean = new ThreadBean();
BeanUtils.copyProperties( threadBean, postForm );
... and then you get a new instance of ThreadHandler here:
ThreadHandler thandler = new ThreadHandler();
At this point, ThreadHandler knows nothing of your populated
instance of ThreadBean. Instead it is getting values from
its own empty ThreadBean parent here:
class ThreadHandler extends ThreadBean
{
String receiver = getReceiver();
String sender = getSender();
String threadTopic = getPostTopic();
String threadBody = getPostBody();
Timestamp threadCreationDate =
getThreadCreationDate();
int threadViewCount = getThreadViewCount();
int threadReplyCount = getThreadReplyCount();
.
.
}
...unless you do something like the following in
ThreadHandler.insertThread():
public int insertThread(ThreadBean bean) throws SomeException {
this.receiver = bean.getReceiver();
this.sender = bean.getSender();
// insert code here
}
which from a design perspective, I'm not sure why you would want to do it
this way.

Subject: RE: All The Bean Properties Are Null in the Business Tier!!!
(Used BeanUtils to Convert DynaValidatorForm)
I have narrowed down the problem. Something went
wrong in my business tier class (ThreadHandler.java).
All the properties in the JavaBean are populated
properly (I have checked). The way I coded in the
ThreadHandler class failed to retrieve the value of
all the properties in the JavaBean (ThreadBean.java).
All the values turned out to be null or 0. Now, what
is wrong with the code?
class ThreadHandler extends ThreadBean
{
String receiver = getReceiver();
String sender = getSender();
String threadTopic = getPostTopic();
String threadBody = getPostBody();
Timestamp threadCreationDate =
getThreadCreationDate();
int threadViewCount = getThreadViewCount();
int threadReplyCount = getThreadReplyCount();
.
.
}
To answer your question:
1. Have you checked to make sure that the fields you
expect actually exist in the form before calling
BeanUtils.copyProperties()?
Yes, I have printed out the contents of the JSP text
fields in my action class, which is a servlet. For
example: System.out.println( the sender is +
postForm.get( sender ) );
2. If so, have you checked to see if the data was
copied properly just after BeanUtils.copyProperties()?
Yes, I have also printed out the value of the bean
properties. For example: System.out.println( the
sender is + threadBean.getSender() );
3. BeanUtils.copyProperties() uses reflection to copy
properties. Are you using proper JavaBeans naming
convention?
Yes, I used a pair of get and set methods for each
properties in the JavaBean (ThreadBean.java). And in
my action class, I could print out the value of those
properties.

BeanUtils.populate() uses reflection to copy

Try and isolate exactly where the data is getting
lost.
I use BeanUtils.populate() all the time with
DynaForms and
have no problems. Usually when I do, I find that my

throws throws MessageDAOSysException, ObjectNotFoundException {
int identity = 0;
md.createThread(bean.getReceiver(),
bean.getSender(),
bean.getThreadTopic(),
bean.getThreadBody(),

// get identity
return identity;
}
}
ThreadBean bean = new ThreadBean();

ThreadHandler th = new ThreadHandler()
th.insertThread(bean);
If you do it this way, then it would be better if ThreadHandler was a
singleton,
but that's a different discussion :)
METHOD 2:
Another way to do it (design by composition).
public final class ThreadHandler {
MessageDAO md = new MySQLMessageDAO();
ThreadBean bean;
public ThreadHandler(ThreadBean bean) {
this.bean = bean;
}
public int insertThread()
throws throws MessageDAOSysException, ObjectNotFoundException {
int identity = 0;
md.createThread(bean.getReceiver(),
bean.getSender(),
bean.getThreadTopic(),
bean.getThreadBody(),
bean.getThreadCreationDate(),
bean.getThreadViewCount(),
bean.getThreadReplyCount());
// get identity
return identity;
}
}
ThreadBean bean = new ThreadBean();
BeanUtils.copyProperties(bean, postForm);
ThreadHandler th = new ThreadHandler(bean)
th.insertThread();
METHOD 3:
Yet another way via classic inheritance:
public final class ThreadHandler
extends ThreadBean {
MessageDAO md = new MySQLMessageDAO();
public ThreadHandler() {
super();
}
public int insertThread()
throws throws MessageDAOSysException, ObjectNotFoundException {
int identity = 0;
md.createThread(this.getReceiver(),
this.getSender(),
this.getThreadTopic(),
this.getThreadBody(),
this.getThreadCreationDate(),
this.getThreadViewCount(),
this.getThreadReplyCount());
// get identity
return identity;
}
}
ThreadHandler th = new ThreadHandler();
BeanUtils.copyProperties(th, postForm);
th.insertThread();

I don't think ThreadHandler represents a java.lang.Thread handler.
I think it more or less is a business object to facilitate persistance.
I think the use of the word Thread here is more representative of a
forum discussion thread.
I could be wrong though.

Caroline,
May I ask why you are performing your database updates through a separate
thread? It seems to be complicating your code. Creating lots of
threads from
within your web application is not a good practice if you want your app to
scale well. Also, what happens if the update doesn't succeed? You have no
way of notifying the user.
The code:
snip
ThreadBean threadBean = new ThreadBean();
String receiver = threadBean.getReceiver();
String sender = threadBean.getSender();
/snip
is your problem unless your ThreadBean constructor can populate itself
correctly with the desired values.
If you must use threads, then you should be able to create a
ThreadHandler,
call a setter method on it and set you ThreadBean instance variable, and
then call the run method on the ThreadHandler to start the thread.
Regards,
Richard

If indeed you want ThreadHandler to inherit from

you should be able to do something like this:
DynaActionForm postForm = ( DynaActionForm )form; ThreadHander = new
ThreadHandler(); BeanUtils.copyProperties( threadHandler, postForm );
threadHandler.insertThread();
The reason you are getting null and zero values in ThreadHandler
is that you are populating a new instance of
ThreadBean here:
DynaActionForm postForm = ( DynaActionForm
)form;
ThreadBean threadBean = new ThreadBean();
BeanUtils.copyProperties( threadBean, postForm
);
... and then you get a new instance of ThreadHandler
here:
ThreadHandler thandler = new ThreadHandler();
At this point, ThreadHandler knows nothing of your
populated
instance of ThreadBean. Instead it is getting values
from
its own empty ThreadBean parent here:
class ThreadHandler extends ThreadBean
{
String receiver = getReceiver();
String sender = getSender();
String threadTopic = getPostTopic();
String threadBody = getPostBody();
Timestamp threadCreationDate =
getThreadCreationDate();
int threadViewCount = getThreadViewCount();
int threadReplyCount = getThreadReplyCount();

ThreadHandler.insertThread():
public int insertThread(ThreadBean bean) throws
SomeException {

RE: dynamic parameters to DynaActionForm
Nathan, could you explain in a little more detail:
Is is a use case where you retrieve a value from somewhere
which tells you how many empty fields to generate and this value
could vary. Then these empty fields are populated with user input
and sent to the server to update the database.
If so, you could do the following:
I would also use org.apache.commons.collections.ListUtils.lazyList()
implementation.
http://jakarta.apache.org/commons/collections/api/org/apache/commons/collect
ions/ListUtils.html#lazyList(java.util.List,%20org.apache.commons.collection
s.Factory)
The lazyList implementation will create a new object using the
specified Factory when Struts indexes into a position in the list
which is null.
form-bean name=myForm
type=com.company.MyForm
form-property name=colors
type=java.util.List/
/form-bean
Subclass your DynaActionForm and override the reset()
public final class MyForm extends DynaActionForm {
private static Logger logger = Logger
.getLogger(SearchContractsForm.class.getName());
/**
* Reset all bean properties to their default state. This method is
* called before the properties are repopulated by the controller
servlet.
* p
* The default implementation uses the initial value specified in the
* FormPropertyConfig element for each property.
*
* @param mapping The mapping used to select this instance
* @param request The servlet request we are processing
*/
public void reset(ActionMapping mapping, HttpServletRequest request) {
super.reset(mapping, request);
List colors = ListUtils.lazyList(new ArrayList(), new
StringFactory());
this.set(colors, colors);
}
/**
* codeStringFactory/code
*
* @see org.apache.commons.ListUtils
*/
class StringFactory implements Factory {
/**
* Create a new instance of the specified object
*/
public Object create() {
return new String();
}
}
}
Define an action which is invoked prior to displaying the jsp.
In the action populate the colors data member with a List of
empty Strings.
In the page do one of the following:
One way to display the values is like so:
c:forEach var=color items${myForm.colors} varStatus=status
c:set var=property value=colors[${status.index}]/
html_el:text property=${property}/
/c:forEach
Another way would be to leverage the Struts tags:
logic:iterate id=color name=myForm property=colors
html:text name=colors property=color indexed=true/
/logic:iterate
Either way should render html like:
input type=text name=colors[0] value=/
input type=text name=colors[1] value=/
input type=text name=colors[2] value=/
input type=text name=colors[3] value=/
input type=text name=colors[4] value=/
...
input type=text name=colors[n] value=/
Upon submitting the form, Struts will invoke reset() and
populate the colors data member with a new lazy list.
When Struts indexes into an empty location, lazy list will
first create a new String at that location and then
Struts will populate that with the value sent from the client.
That should give you a better idea of how to use indexed properties.
hth,
robert

The amount of parameters in the form are dynamic. How or what type of

RE: All The Bean Properties Are Null in the Business Tier!!! (Used BeanUtils to Convert DynaValidatorForm)
Have you checked to make sure that the fields you expect
actually exist in the form before calling BeanUtils.populate()?
If so, have you checked to see if the data was copied properly
just after BeanUtils.populate()?
BeanUtils.populate() uses reflection to copy properties.
Are you usingproper JavaBeans naming convention?
Try and isolate exactly where the data is getting lost.
I use BeanUtils.populate() all the time with DynaForms and
have no problems. Usually when I do, I find that my data member
names don't correspond.

Subject: All The Bean Properties Are Null in the Business Tier!!! (Used

Hi, my program compiled OKay. When I ran the
application, somehow, the properties of my
DynaValidatorForm are not passed from the action class
to the business tier and then to the data access tier.
Please help me taking a look at what went wrong.
It looks that the validation worked fine:
form-bean
name=postForm
type=org.apache.struts.validator.DynaValidatorForm
form-property
name=receiver
type=java.lang.String/
form-property
name=sender
type=java.lang.String/
.
.
/form-bean
because when I intentionally left several of the text
fields blank and submitted my JSP form, an applet got
prompted showing something in those fields are
required.
In my action class (see below), I used BeanUtils to
copy all the properties of the DynaValidatorForm to a
bean (ThreadBean):
DynaActionForm postForm = ( DynaActionForm )form;
ThreadBean threadBean = new ThreadBean();
BeanUtils.copyProperties( threadBean, postForm );
I then added a number of properties with pre-defined
values to the ThreadBean in the Action class:
Timestamp now = DateUtil.getCurrentGMTTimestamp();
threadBean.setThreadCreationDate( now );
threadBean.setThreadViewCount( 0 );
I then called a method in a service class
ThreadHandler and passing threadBean as the parameter
of that method:
ThreadHandler thandler = new ThreadHandler();
threadID = thandler.insertThread( threadBean );
In the ThreadHandler class (see below), I first tried
to retrieve the values of those properties from the
ThreadBean. I FOUND OUT ALL THOSE VALUES ARE NULL!
class ThreadHandler extends ThreadBean
{
int threadID = getThreadID();
String receiver = getReceiver();
String sender = getSender();
Timestamp threadCreationDate =
getThreadCreationDate();
int threadViewCount = getThreadViewCount();

The application I'm working on is a support portal where you can download technical document, drivers etc. The tricky part is, that certain documents should be only accessible to users with a certain role. My idea so far is to put a user object in the session and to evaluate the role (and therefore the access level) of the user for all views that are displaying data which might be restricted. I guess the easiest way would be using a jsp tag like security:checkAccessLevel / which would retrieve the user object from the session (if it exists) and the then filter the data accordingly. Is there such security taglib around? Has anybody worked on a similar scenario? What is the best approach to solve this problem? Is there a best practice for it?

RE: DynaBean with JSTL
As long as the DynaBean implentation exposes a Map interface then yes.
For example, DynaActionForm implements DynaBean and exposes a Map interface,
so if you had a property named customerName, in a form bean named
customerDetailForm,
then you could render that property like so using JSTL.

RE: How To Output the Value of a String That Is Passed From Another JSP?
Hi, thank you for your attention to my problem. First
all, I think that I am missing someting. In order to
use the c:set and c:out ... tags, I think
that I have to import a taglib into my JSP and assign
it with a prefix c. Which taglib should I import?
Right now, I have these:
%@ taglib uri=/tags/struts-html prefix=html %
%@ taglib uri=/tags/struts-bean prefix=bean %
%@ taglib uri=/tags/struts-logic prefix=logic %
%@ taglib uri=/tags/tiles prefix=tiles %
%@ taglib uri=/tags/request prefix=req %
You are missing this one:
%@ taglib uri=http://java.sun.com/jsp/jstl/core; prefix=c %
Second,
html:form action=/list/Message
c:set var=cr value=${articleForm.creator}
scope=session/
c:out value=${cr}/
html:submitView/Send Messages/html:submit
/html:form
%-- The statement below has no problem to write on
the value --%
bean:write name=articleForm property=creator/
That's because you were missing the JSTL taglib directive
above.
Third, the mapping to the next JSP is:
action
roles=administrator,editor,contributor
path=/list/Message
forward=.message.Form
name=postForm
scope=session
validate=false/
Why are you defining an action path at all.
Once you add the JSTL taglib directive the following
line places the value in the session. There is no
need to submit.
c:set var=cr value=${articleForm.creator} scope=session/
Fourth, in the postForm.jsp, I try to retrieve the
value of the String that is passed in a session object
and print it out in a text field:
bean:define id=author name=cr scope=session
type=java.lang.String/
html:text property=creator value=%=author%
size=82 maxlength=25 tabindex=1/
You could use Struts-EL and do something like:
html_el:text property=creator value=${cr}/
The Struts-EL taglib and jar file can be found in the /contrib directory
of the Struts distribution.
Fifth, the error message is that cr cannot be found
in the session scope.
Once again, this is because the JSTL taglib directive is missing.

If you can explain your intent, maybe we can suggest

Is articleForm associated with action mapping
/list/Message?
If so, then you could do something like:
html:form action=/list/Message
html:hidden property=creator/
html:submitView/Send Messages/html:submit
/html:form
This of course, assumes you have already populated
creator in
articleForm in some other action using the same
form.
The action with mapping /list/Message, which
processes articleForm could
do something like:
MyForm articleForm = (MyForm) form;
String creator = articleForm.getCreator();
request.getSession().setAttribute(creator,
creator);
return mapping.findForward(success);
In JSP#2 you could do something like this:

To control when reset() affects my form properties I subclassed the action form and subclassed ActionMapping to add an isReset() setReset(boolean reset) methods so I can declaratively define when reset is to be used by adding the following line in my struts-config file: set-property property=reset value=false/ robert -Original Message- From: vasudevrao gupta [mailto:[EMAIL PROTECTED] Sent: Thursday, December 18, 2003 12:30 AM To: 'Struts Users Mailing List' Subject: Help needed in form beans Hi All, I have a same form bean for 5 JSP's(JSP1,JSP2,JSP3,JSP4,JSP5) All the JSP's use the same form bean.I am keeping the form bean in the session scope.

Subject: logic:iterate inside a logic:iterate ??
Hi
I'am a Struts newbie, sorry if it is a classic question.
My question is about logic:iterate
I have a vector of documents.
In my application a document is a vector of LabelValueBean. I wish to
write both the label and the value.
I wish to write all my documents so I iterate through my vector
of documents.
But after that how can I iterate through my vector of LabelValueBean ???
Basically here's what I want to do :
for_each_document
{
for_each_LabelValueBean_in_the_current_document
{
write LabelValueBean.Label;
write LabelValueBean.Value;
}
}
thanks for you help

RE: Newbie: java.lang.boolean and DynaActionForm?
To address the fundemental question, it is considered a best practice to only use String or Boolean objects or collections of String and/or Boolean objects or collection of data structures which contain String and/or Boolean objects in your forms. This is because it gives you more control over validation. This doesn't mean that DynaActionForms or any DynaForm for that matter doesn't support non-string types. It supports any Object because essentially the DynaXXXForms internal data structure is a Map. In general the Struts form should be a ValueObject passing immutable data from the input to be processed or passing immutable data to the output to be rendered. The great thing about Struts is that it gives you more than enough rope to use wisely or hang yourself :) robert -Original Message- From: Engbers, ir. J.B.O.M. [mailto:[EMAIL PROTECTED] Sent: Wednesday, December 17, 2003 9:24 AM To: '[EMAIL PROTECTED]' Subject: Newbie: java.lang.boolean and DynaActionForm? Hi, Both 'Struts in Action' and 'Programming Jakarta Struts' state that ActionForms and DynaActionForms are nearly equivalent and the main advantage of using DynaActionForms is that you don't have to declare all the getters and setters. In DynaAction Forms each property can be of a (array of a) primitive types. Thanks to Pedro Salgado and Martin Gainty (see Retrieving boolean properties from a DynaActionForm on december 16), I partially succeeded in solving the first problem which only confronted me with the next problem :-( And while looking for a solution to that problem, I found a bugreport (23355) in which Craig states that 'Adding these (getInteger, getBoolean etc, Ben) would encourage a behavior that Struts discourages -- using non-String data types in a form bean.' Maybe that this explains why I have only found examples that use String-properties (which lead me to my first question: where can I find examples that use non_string properties?) but it leaves me with the more fundamental question: Why do DynaActionForms offer the possibility to declare non-String properties without supporting them? Should I avoid using DynaActionForms at all and use the DynaValidatorForm?

RE: How To Output the Value of a String That Is Passed From Another JSP?
What exactly are you trying to accomplish? What's the
high level view?
If you can explain your intent, maybe we can suggest an easier
way to accomplish your goal.
Is articleForm associated with action mapping /list/Message?
If so, then you could do something like:
html:form action=/list/Message
html:hidden property=creator/
html:submitView/Send Messages/html:submit
/html:form
This of course, assumes you have already populated creator in
articleForm in some other action using the same form.
The action with mapping /list/Message, which processes articleForm could
do something like:
MyForm articleForm = (MyForm) form;
String creator = articleForm.getCreator();
request.getSession().setAttribute(creator, creator);
return mapping.findForward(success);
In JSP#2 you could do something like this:
c:out value=${creator}/

RE: How To Output the Value of a String That Is Passed From Another JSP?
Are you sure that c:set var=cr value=${articleForm.creator}
scope=session/
is placing the value in the intended scope?
Try doing this:
html:form action=/list/Message
c:set var=cr value=${articleForm.creator}scope=session/
c:out value=${cr}/
html:submitView/Send Messages/html:submit
/html:form
To make sure it is actually putting the value in session scope.
If so, then on postForm.jsp try using scriplets to make sure that
the value can be accessed. If it can, then do you have all of your
tag library directives in your pages?
