FW: [ANN] Bridgetown IoC Framework
FYI -Original Message- From: Peter A. Pilgrim [mailto:[EMAIL PROTECTED] Sent: 08 September 2004 07:12 To: Struts Developers List Subject: [ANN] Bridgetown IoC Framework Hi I have been quietly working on my own Inversion of Control lightweight framework over the last couple of months. My itch was scratched when I suddenly realised that ``Commons BeanUtils'' and ``Common Digester'' could be simply combined together into a bean assembly factory. An assembly factory could manage service beans in a lightweight container. Services could then be retrieved by name, and one doesn't have to worry about connecting different services together. Experiments showed that this idea was pretty cool and have implemented property and method dependency injection (aka ``BeanUtils'' and ``MethodUtils''). [Constructor injection is on the todo list. ] I am at the point where the current codebase is stable enough for development, but if I want the container to be more useful, then I need to open- source the project. It would allow others to write Dynamic proxy service beans, integrate with Struts 1.2/2+, or extend with AOP library, or whatever persistence layer EJB 3.0 decides to become. It cannot be down by just one man writing software. As an independent consultant I simply have not got the time to build everything. Moreover, I intend to follow the Struts style ``open integration'' philosophy that should allow Bridgetown IoC container to be added any other framework. (I intend add support to the Expresso Framework in the near term, since I am a core committer there) So my simple IoC Test Container became ``Bridgetown IoC''. I uploaded the source code to ``Sourceforge'' and slapped on it an Apache License 2.0 badge. The software is ALPHA quality but it compiles and run with Eclipse SDK 3, and there are junit test and a couple of examples. `` http://bridgetown.sf.net '' is the hook. I'd like publicly thank the man, Craig McClanahan, for his two inventions `BeanUtils' and `Digester'. Without those two components it just wouldn't have happened.

RE: html:cancel usage
Hi, Has anyone else had a problem with this? I am using Struts 1.1 but presume it has worked in this and previous versions as it must come up in almost every project. I cannot switch validation to false as my submit button does require validation. I suppose I could put the cancel and submit buttons inside seperate form tags but this seems a little contrived.

Doing and maintain wizards with struts is really easy , specially for long life projects. Can you see how easily one simple field propagates the amount of activities just because of the ActionForm in the middle? ActionForm are really usefull when a lot of forms that use the same fields (select menu or textfield or whatever). I create an ActionFormBase which contain all dropdown menus contents and basic validation, extend it when neeeded to add specific fields, and never have to bother with the common fields again in the whole application. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Proper place for validation
Hmm, not a lot of comments on this. I guess there is a consensus on the
matter (that, or no-one really gives a damn).
A quick followup on this; how could I achieve both
a) decoupling of my business classes from Struts
b) internationalization
if I validate in my business class?
1)
if (alreadyExists(email)) {
throw new MyAppException(E-mail address already exists);
achieves a) but not b), and
2)
if (alreadyExists(email)) {
throw new MyAppException(errors.email.duplicate);
achieves b) but not a)

I would avoid putting any business logic in the action
class. Place this type of logic in the business class as it
most likely is validation that is valid across all application
logic and not for just one use case.

Subject: Proper place for validation
I am wondering what would be the propert place for some validation code.
Let's say I have a registration page where user inputs his/her
information
for a new user account. There's a field for e-mail address. On one level
that information is validated on the ActionForm, for things such as
- field is not left empty, if it is required
- field is a valid e-mail address
That much seems quite clear. But where should I put a check that ensures
that same e-mail address is not already used by an existing account?
On the other hand, I could put it in the registration action, because
checking that is (kind of) user-input validation, and action is a
natural
place to do this.
On the other hand, I could put it in my business class. The pros for
this
would be smaller and simpler action code, and reuse if same check is
needed
with different actions.
Any suggestions? Intuitively, I think I would put that check in the
Action,
but I am happy to hear any arguments in favor or opposing that.

Bean tag and session data issue
Having overcome my validation problem with help from the list (thanks
Bill) I now find myself banging my head against another wall.
I now have a multi-page form backed by an ActionForm and an Action that
appears to work fine (stepping from one page to the next, accepting
input, validating it, storing it in an object in a session) except for
the fact that the JSP pages do not retrieve the accumulating data from
the object stored in the session, other than the first piece of data
entered and the last. So I get a growing number of blank fields in the
page.
I have built and run a multi-step unit test with Struts Test Case that
works fine. The Action creates the required object, stores it in the
session, and adds the data piece by piece as the unit test simulates
stepping through the wizard.
This has at my wits end.
Below is the code from the Action and one of the JSP pages that fails.
Note: Only the first four pages are currently processed by business
logic. The rest just return success regardless.
I can't see what I am doing wrong. It seems like the object stored in
the session isn't being updated properly (although the unit test
disproves this), so perhaps its something I have messed up in the JSP,
or don't fully understand?
Any assistance anyone can offer would be greatfully received.
Regards,
Langdon

Database Mapping
Hai All, Will it be possible in the Struts to do some mapping between the form fields and underlining database by writing queries in the xml file. I want to develop a prototype with some functionality and do not want to do coding for this or minimal I saw similar functionality with JDBC Connection Servlet Framework (jcs) http://jresources.com But the problem is that the support for this seems to have been removed. If someone has got the JAR file concerning this framework then please send it to me. Any indication on this will be very helpful.

Re: Database Mapping
I'm not exactly sure what you are asking. If you asking if Struts supports putting sql in the configuration files, then the answer is no. If you wanting some automatic framework to write your sql for you, then the answer is yes and no. No, you can't do it with Struts config files, but yes, it can be done and easily used by your classes with the Struts framework. There are an infinite number of ways to connect your Struts application with a database. It all depends on your requirements. Give us more detail and you might get a few recommendations..thx. -- James Mitchell Software Engineer / Open Source Evangelist EdgeTech, Inc. 678.910.8017 AIM: jmitchtx - Original Message - From: Shailender Jain [EMAIL PROTECTED] To: [EMAIL PROTECTED] Cc: Anusharan Tiwari [EMAIL PROTECTED]; Tapas Tiwari [EMAIL PROTECTED] Sent: Wednesday, September 08, 2004 8:12 AM Subject: Database Mapping Hai All, Will it be possible in the Struts to do some mapping between the form fields and underlining database by writing queries in the xml file.

Re: ActionForm with all application attributes
Bill, wait a minute, i just thought on something. I wouldn't matter if a hacker set a attributes in my BaseActionFomr, if i don't use it to build my DTOs. I mount my DTOs case specific, so i'd just ignore the hacker set attribute. But if this hacker set attribute is in my DTO, i agree that i could get problems. But if this attribute is present in the DTO it means that even if i was using the traditional way this attribute would present in the traditional ActionForm and, consequently, would be suceptible to the same problem.

[OT] RE: [ANN] Bridgetown IoC Framework
This is off topic to the Struts list. Also not forgetting Avalon, PicoContainer, etc from my POV. Admittedly these mature containers have been around for sometime. Here are my motivations: 1) To scratch the itch. Build a tiny container/kernel that I could experiment with in Expresso / Struts. The idea is make an assembler that can be merged into another toolkit. (My goal is to make Bridgetown a first class citizen in Expresso, but I am still scratching my head about this issue.) 2) I wanted to implement ``method injection''. 3) Build a pizza base, that I could extend later with a dynamic proxy generation / interceptors. Maybe directly support or use the Commons Chain (this is still very fuzzy in my mind.) 4) Eventually make services beans and service oriented architecture first class citizen of a ioc framework. 5) Fun: I wanted to experiment with Jakarta technologies. 6) Learning: I wanted to build something small and wonderful and it will be always free and open source. I enabled the sf.net mailing lists, so if you want to discuss further I suggest we take this thread over there. -- Peter Pilgrim Operations/IT - Credit Suisse First Boston, 10 South Colonnade, London E14 4QJ, United Kingdom Tel: +44 (0)207 883 4447 -Original Message- From: Robert Taylor [mailto:[EMAIL PROTECTED] Sent: 08 September 2004 14:10 To: Struts Users Mailing List Subject: RE: [ANN] Bridgetown IoC Framework Peter, this sounds interesting, but what would Bridgetown offer over a more mature IoC container like Spring? robert -Original Message- From: Pilgrim, Peter [mailto:[EMAIL PROTECTED] Sent: Wednesday, September 08, 2004 3:52 AM To: Struts User Apache (E-mail) Subject: FW: [ANN] Bridgetown IoC Framework FYI -Original Message- From: Peter A.

[Constructor injection is on the todo list. ] I am at the point where the current codebase is stable enough for development, but if I want the container to be more useful, then I need to open- source the project. It would allow others to write Dynamic proxy service beans, integrate with Struts 1.2/2+, or extend with AOP library, or whatever persistence layer EJB 3.0 decides to become. It cannot be down by just one man writing software. As an independent consultant I simply have not got the time to build everything. Moreover, I intend to follow the Struts style ``open integration'' philosophy that should allow Bridgetown IoC container to be added any other framework. (I intend add support to the Expresso Framework in the near term, since I am a core committer there) So my simple IoC Test Container became ``Bridgetown IoC''. I uploaded the source code to ``Sourceforge'' and slapped on it an Apache License 2.0 badge. The software is ALPHA quality but it compiles and run with Eclipse SDK 3, and there are junit test and a couple of examples. `` http://bridgetown.sf.net '' is the hook. I'd like publicly thank the man, Craig McClanahan, for his two inventions `BeanUtils' and `Digester'. Without those two components it just wouldn't have happened.

Re: How to resolve label in ActionMessage?
You might be able to. Action.getResources() is actually implemented as return ((MessageResources) request.getAttribute(Globals.MESSAGES_KEY)); So try that to get the message resources, then call getMessage() on that.

The first parameter of the ActionMessage constructor is the message key. The rest (which are optional), are the actual parameters to the message. If your parameter is itself in need of evaluation, you'll need to do that yourself before you pass that on to ActionMessage. For that, you can call getResources(request).getMessage(activity.description) in your action. There are also getMessage() methods that take in a locale and parameters.

ActionForm data type X BeanUtils - using Dates
Hi, i believe that a lot of developers use BeanUtils to copy the data from ActionForms to the specific DTOs. I've used this approach, but right now i'm facing a problem, not a big one. I've allways been confused about working with dates in Java. I got a jsp where the user must input a date in the following format. Date: dd/mm/ That's how we use dates in Brazil: the day, month and year. I'd like to make a validation if the user input the date in the correct manner in the ActionForm (i'm using traditional validation and the user input comes in a String). So, keeping in mind the variou ways of doing this date validation (even the deprecated ones), how should a do the date validation Which one is the best way??? I just want to check if the user input a day with 2 digits, a slash, a month with 2 digits, a slash and a year with 4 digits. Also, after that i'd like to copy this form data to my DTO with BeanUtils. Which type should i use in my DTO for this date??? Thanks, Leandro. ___ Yahoo!

Re: Validating single fields in multi-page forms
Well, if I recall from your original post you only wanted to validate the fields on the current page only. Validator provides support for a page attribute that you can use for wizard-style forms. Validator will use that attribute to validate form fields on the current page and any previous pages. The reason it does the previous page is primarily for security since you cannot guarantee that form properties were set from the intended page. - Bill Siggelkow Langdon Stevenson wrote: Hi Bill Thanks for your suggestion. I have switched to ValidatorActionForm for my validation and now get the desired result (validation of only the fields that appear on the specific page). So problem solved! I am curious though about your interpretation of wizard style. The form is indeed wizard like, would you do things differently because of that? Langdon Bill Siggelkow wrote: If I understand you correctly, you are using a form for multiple-pages but not in a wizard fashion. The best way to do this is to use path-mapping for validator -- in this case your form extends ValidatorActionForm (or DynaValidatorActionForm) and you specify the path to the action for the form name in the validation.xml ... form name=/Foo/Bar ... for this action, only these fields will be validated... /form Bill Siggelkow Langdon Stevenson wrote: Hi I have a multi-page form (about 8 pages total) that take just a few fields per page that I am implementing in Struts (this is my first Struts project). - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: ActionForm with all application attributes
True -- some people use bulk property setters like those provided by BeanUtils to move data from the ActionForm to the DTO -- I think that is primarily where you would need to be careful. Personally, I am not fond of the use of an uber form; it doesn't seem very object-oriented; however, I can see advantages for small applications. - Bill Siggelkow Leandro Melo wrote: Bill, wait a minute, i just thought on something. I wouldn't matter if a hacker set a attributes in my BaseActionFomr, if i don't use it to build my DTOs. I mount my DTOs case specific, so i'd just ignore the hacker set attribute. But if this hacker set attribute is in my DTO, i agree that i could get problems.

Got the point??? --- Bill Siggelkow [EMAIL PROTECTED] escreveu: Are all of your getters and setters public? If so, (which I assume is true), one disadavantage is that request parameters can be passed in that set stuff on the form that you may not be expecting. For example, suppose your uber form supports properties for 'foo' 'bar' and 'baz'. Let's say one form sets the first two properties -- from a GET you would see: http://localhost/myapp/SubmitFooBar.do?foo=blahbar=glob Now suppose some hacker comes along and does the following: http://localhost/myapp/SubmitFooBar.do?foo=blahbar=globbaz=evilvalue Now, the property for baz has been set when you weren't expecting it to. - Bill Siggelkow Leandro Melo wrote: Hi, i sent this question yesterday, but as nowbody answered me, i trying it again with a more sifinificant title (sorry for the re-post).

Having overcome my validation problem with help from the list (thanks
Bill) I now find myself banging my head against another wall.
I now have a multi-page form backed by an ActionForm and an Action that
appears to work fine (stepping from one page to the next, accepting
input, validating it, storing it in an object in a session) except for
the fact that the JSP pages do not retrieve the accumulating data from
the object stored in the session, other than the first piece of data
entered and the last. So I get a growing number of blank fields in the
page.
I have built and run a multi-step unit test with Struts Test Case that
works fine. The Action creates the required object, stores it in the
session, and adds the data piece by piece as the unit test simulates
stepping through the wizard.
This has at my wits end.
Below is the code from the Action and one of the JSP pages that fails.
Note: Only the first four pages are currently processed by business
logic. The rest just return success regardless.
I can't see what I am doing wrong. It seems like the object stored in
the session isn't being updated properly (although the unit test
disproves this), so perhaps its something I have messed up in the JSP,
or don't fully understand?
Any assistance anyone can offer would be greatfully received.

Re: Struts XDoclet examples
That's good information; I read it with vigor... As you can tell, I'm excited by the prospects of using XDoclet instead of insert proprietary tool here. And, I think I get the gist of Struts related support provided in XDoclet, but I have a couple of questions. 1 -- How good is the DynaValidatorForm support? I saw the announcement: http://www.systemmobile.com/code/xdoclet-dynaform-README.txt. That looks well and good, but there appear to be some discrepancies: Class Level Tags: @struts.dynaform Attributes: name- The name of the form bean in the config. [required] type- The type of DynaForm. [required] description - Descriptive string. [optional] className - The config class. [optional] validate- If set, the validator code will generate a form definition for this dynaform. [optional] Method Level Tags: @struts.dynaform-field Attributes: name - The name of the form field. If not specified, the property name of the method is used. [optional] What method? I thought this was a dynaform? type - The type of field. If not specified, the return type of the getter is used. [optional] Again, we're talking about dynaforms... I'm going to put these XDoclet tags in an Action, I presume. Is there support for DispatchActions? I'm just starting to dig into this tool. I may end up adding some code of my own to these projects, just so I don't sound like a whiner.

Didn't see this post, but yes there could be 1 to many between ActinForm and DTO's, and this is not a problem. ActionForms directly represent what is on the screen, while DTO's represent your data.

It's very usual to have more than 1 action form validating the same field, what may causes some duplication and a harder maintenance. A central unit of validation and resetting suits this problem very well. The strtus validate stuff is centralized, and easier to configure. Doing it all in one class, means that at some point your going to have logic to handle special cases The more of these you have hte more complex the logic... Complex logic is directly related to the stability of your code. In addition I don't have to code the validations myself. Just specify what I want validated and I'm done. You could do the same thing, however you still have to glue it all together. - With this approach i can perform light business validation that must be done in java code. So, for one or more situation i could access some util classes that do some validation for me. You can do this with custom validation classes and still achieve centralizations. Depending on what you mean by light business validation. I like consistency in where things are. Business rules in business layer, and validation in the view tier. A newcomer to the app would have to guess (yeah, sure they'll ask, maybe) where the code is supposed to go. - With this approach i have very small action forms that basically has a validate and reset methods that just delegate to the WebValidation and WebReset classes. With the standard struts approach I have even smaller action classes no validate or reset methods. - With this approach i also have a central unit of fields and their types, so if it's necessary to chance them, i don't need to go through all the action forms that have these fields. You can do this with a base action form. This approach will only work correctly if you don't have fields with the same name in your application. Naturally, this is not a drawback because forces you to use a nice use of software engineering forcing you to give significant names for the fiels. Not entirely true. I have several fields that get validated differently based on where they come from, or where the data is going (some customers will accept a phone number that is 10-30 numbers, -() and '.', others want a US phone number). Right now, I use a different form bean for each, and use a common base class for everything. The different child class allows for different completely different validations, which is what I need. Doing it your way would make this customization much harder, since I would have to sublcass the validation class too. With struts 1.2, I can use inheritance and make this even easier then the copy and paste I use now. Well, i'd appreciate comments (bad or nice ones) on that. Thanks, Leandro ___ Yahoo!

Hmm, not a lot of comments on this. I guess there is a
consensus on the
matter (that, or no-one really gives a damn).
A quick followup on this; how could I achieve both
a) decoupling of my business classes from Struts
b) internationalization
if I validate in my business class?
1)
if (alreadyExists(email)) {
throw new MyAppException(E-mail address already exists);
achieves a) but not b), and
2)
if (alreadyExists(email)) {
throw new MyAppException(errors.email.duplicate);
Simple, you throw EmailAlreadyExists( email), and catch that, or use the exception
handling ability of struts to give an appropriate error message to the user. For
system level stuff (ie DB is missing etc) you inlcude a cause, but don't necessarily
show it to the user.
achieves b) but not a)

I would avoid putting any business logic in the action
class. Place this type of logic in the business class as it
most likely is validation that is valid across all application
logic and not for just one use case.

Subject: Proper place for validation
I am wondering what would be the propert place for some
validation code.
Let's say I have a registration page where user inputs his/her
information
for a new user account. There's a field for e-mail
address. On one level
that information is validated on the ActionForm, for
things such as
- field is not left empty, if it is required
- field is a valid e-mail address
That much seems quite clear. But where should I put a
check that ensures
that same e-mail address is not already used by an
existing account?
On the other hand, I could put it in the registration
action, because
checking that is (kind of) user-input validation, and action is a
natural
place to do this.
On the other hand, I could put it in my business class.
The pros for
this
would be smaller and simpler action code, and reuse if
same check is
needed
with different actions.
Any suggestions? Intuitively, I think I would put that
check in the
Action,
but I am happy to hear any arguments in favor or opposing that.

As you can tell, I'm excited by the prospects of using XDoclet instead of insert proprietary tool here.

I saw the announcement: http://www.systemmobile.com/code/xdoclet-dynaform-README.txt. That looks well and good, but there appear to be some discrepancies: Class Level Tags: @struts.dynaform Attributes: name- The name of the form bean in the config.

[optional] validate- If set, the validator code will generate a form definition for this dynaform. [optional] Method Level Tags: @struts.dynaform-field Attributes: name - The name of the form field. If not specified, the property name of the method is used. [optional] What method? I thought this was a dynaform? type - The type of field. If not specified, the return type of the getter is used. [optional] Again, we're talking about dynaforms... I'm going to put these XDoclet tags in an Action, I presume. Is there support for DispatchActions? I'm just starting to dig into this tool.

What happens if your cleaning lady/cow-orker/boss kicks the network cable out of the DB? Or the network cable goes bad? Where do these kinds of things get handled?[1] Which is why I like chained exceptions. The DAO layer has an issue, that's a specific message that the business layer wraps up in an exception that get tossed up to presentation, where the struts exception handler decides what to dispaly, and how to dispaly it. Error messages are a presentation tier responsibility. In the business tier, the exception should be able to communicate with other objects what the error was. The way I do this is with specific exception types or with error codes. If the exception is caught by another business tier object, it can check the error code to see what exactly happened. If it bubbles up all the way to the presentation tier, it can do the same, and then select an i18n error message to show, or other take other action as needed. I agree... handle the right exception at the right time, but never ignore.

Kind of being picky here, but I wouldn't switch the property name like
that -- instead; since the form field would be a String I would use
String getPaymentDateString() {...} in the ActionForm and
Date getPaymentDate() {...} in the domain object.

strange random problem
Since I have rewrited an important part of my application using struts
I've had this problem several times. It didn't happen in development
environment, with only one or two users using the application at the
same time. It happends in production with 20 or 30 users.
* Development environment: Debian GNU/Linux, Jonas 4.1.2 application
server with Tomcat 5.0.25, J2SE 1.4.2, Struts 1.1, MS SQL Server (on
different Win2000 machine)
* Production environment: Win2000 SP4, Jonas 4.1.2 application server
with Tomcat 5.0.25, J2SE 1.4.2, Struts 1.1, MS SQL Server.
All forms are request scoped (I think I don't need session, probably
I'm saving memory). Every of them have implemented the reset method
setting variables to their initial values, this is made in
constructors too.
* This is a bit more complex so I'll try to simplify the explanation
with a generic example:
1. I have one object wich instances can be edited and updated by
users, saving its instance values to a database. I have two actions:
EditObjectAction and UpdateObjectAction, each of them with their forms
(EditObjectForm and UpdateObjectForm).
2. EditObjectForm has only one String attribute that contains the
primary key (id) of the object we want to edit, submitted from a jsp
page.
3. EditObjectAction gets the primary key from the form, instances the
object and call the necesary methods on it in order to load the rest
of object data from database. Then the action put the object in the
request using request.setAttribute(objectName, object) method and
makes a forward (using mapping.findForward(...)) to the page data.jsp.
4. Into the data.jsp page I render the view using struts-html,
struts-html-el and c (JSTL) taglibs, extracting the necessary
information from the request object using JSTL expressions like:
c:out value=${objectName.attribute}/. The html:form/ tag has
this content:
a) Primary key: html-el:hidden property=id value=${objectName.id} /
b) Rest of object data using html_el:text/ and other useful
tags like loops etc.
5. When the user change and submits the data, UpdateObjectForm is
created and filled by struts, content validated, and passed to
UpdateObjectAction. The action takes the id from the form and
instances the object again from database, it updates object values
from the form in memory and database, puts the object into request and
forward to data.jsp again.
6. Data.jsp is rendered from the request object again with the new
submitted data.
Note that the object is NEVER stored into the session. Forms are
request scoped. The only information I keep into session is the logged
user. I don't use application scope.
The problem is that sometimes (about 10% more or less), once the
object is updated, the next view shows data from another different
object instance that is currently being managed by other user. The
forward or the render fails. I thought about a possible coding or
design error, but is it not impossible to access data from other
session? moreover the object is stored into request. Am I using struts
in a correct way? Could it be a taglibs or struts bug or configuration
error? What do you think about trying struts 1.2.2 or using linux in
production? I think probably is much more easy but I don't see it.
Thank you in advance

Re: ActionForm data type X BeanUtils - using Dates
The custom converter is done independently of the action, form or DTO.
First step is to implement the interface
org.apache.commons.beanutils.Converter.
Keep in mind that the converter you are writing uses the appropriate
converter for the original class. So, if you were converting from a
String to a Date, you would create a String converter. And vice versa,
if you were converting from a Date to a String you would create a Date
converter. Example below
Then, to override the standard converters, you call:
ConvertUtils.register(Your converter class, class to use converter
on.class);
First parameter is your new converter, and the second is the class its
used for. I call this in a static initializer of a utility class, you
just need to make sure its called before any validations occur, and it
only needs to be done once.
Since we are interested in customizing conversions from String to Date,
I override the String converter:
public class StringConverter implements Converter{
public Object convert(Class type, Object value) {
Object returnObj = null;
if (value != null) {
if (value instanceof Date){
returnObj = dateFormatter.format((Date)value);
} else if (value instanceof BigDecimal){
returnObj = decimalFormatter.format((BigDecimal)value);
} else {
returnObj = value.toString();
}
}
return returnObj;
}
}
I've left out some properties, their getters and setters, but I think
you get the gist of what I'm doing. Now, I register this converter as such:
ConvertUtils.register(new StringConverter(), String.class);
I actually have a utility class, where the register is done in the
static initializer. I suppose another way would be to use a servlet that
loads prior to Struts.. Or if your Actions have a base class, etc...
Maybe there's a more elegant way of doing that. This is what I've come
up with. If someone has a better way, post please, I'm always looking
for more elegant ways of accomplishing stuff like this.

Subject: strange random problem
Since I have rewrited an important part of my application using struts
I've had this problem several times. It didn't happen in development
environment, with only one or two users using the application at the
same time. It happends in production with 20 or 30 users.
* Development environment: Debian GNU/Linux, Jonas 4.1.2 application
server with Tomcat 5.0.25, J2SE 1.4.2, Struts 1.1, MS SQL Server (on
different Win2000 machine)
* Production environment: Win2000 SP4, Jonas 4.1.2 application server
with Tomcat 5.0.25, J2SE 1.4.2, Struts 1.1, MS SQL Server.
All forms are request scoped (I think I don't need session, probably
I'm saving memory). Every of them have implemented the reset method
setting variables to their initial values, this is made in
constructors too.
* This is a bit more complex so I'll try to simplify the explanation
with a generic example:
1. I have one object wich instances can be edited and updated by
users, saving its instance values to a database. I have two actions:
EditObjectAction and UpdateObjectAction, each of them with their forms
(EditObjectForm and UpdateObjectForm).
2. EditObjectForm has only one String attribute that contains the
primary key (id) of the object we want to edit, submitted from a jsp
page.
3. EditObjectAction gets the primary key from the form, instances the
object and call the necesary methods on it in order to load the rest
of object data from database. Then the action put the object in the
request using request.setAttribute(objectName, object) method and
makes a forward (using mapping.findForward(...)) to the page data.jsp.
4. Into the data.jsp page I render the view using struts-html,
struts-html-el and c (JSTL) taglibs, extracting the necessary
information from the request object using JSTL expressions like:
c:out value=${objectName.attribute}/. The html:form/ tag has
this content:
a) Primary key: html-el:hidden property=id value=${objectName.id}
/
b) Rest of object data using html_el:text/ and other useful
tags like loops etc.
5. When the user change and submits the data, UpdateObjectForm is
created and filled by struts, content validated, and passed to
UpdateObjectAction. The action takes the id from the form and
instances the object again from database, it updates object values
from the form in memory and database, puts the object into request and
forward to data.jsp again.
6. Data.jsp is rendered from the request object again with the new
submitted data.
Note that the object is NEVER stored into the session. Forms are
request scoped. The only information I keep into session is the logged
user. I don't use application scope.
The problem is that sometimes (about 10% more or less), once the
object is updated, the next view shows data from another different
object instance that is currently being managed by other user. The

design error, but is it not impossible to access data from other

Also, if i'm doing something terrible, i'd like to know. Keeping in mind that more than one action form may have to validate and/or reset the same fields, i decided to this. I already have a MyBaseActionForm which incorporates all some methods that i need in my application. I don't use Validator, as i prefer to use java classes for validation ligth business logic. Now, i decided to add ALL fileds (setters and getters) i have in my application as private members of this MyBaseActionForm. Then i created classes WebValidation and WebReset. This classes have validate methods for all fields in my application. These classes can access the fields they need for each method because all my action forms extend the MyBaseActionForm, thus this WebValidation and WebReset classes can call the setters and getters of an y action form to validate with the light business logic i need. I got with this approach a centralized way and component responsible for the validation. All my action forms delegate the validate and reset methods to the classes i mentioned. I'd like to briefly describe some nice benefits of this approach. - With this approach i definetly solve my earlier problem that i posted on question 1:N relationships - ActionForm x DTOs. Didn't see this post, but yes there could be 1 to many between ActinForm and DTO's, and this is not a problem. ActionForms directly represent what is on the screen, while DTO's represent your data. You have a 1-to-many relationship between screens and tables. - With this approach i got no coupling between my ActionForm and DTOs. What do you mean by coupling? You still have to transfer data to and from the DTO. - With this approach i have a centralized validate unit. It's very usual to have more than 1 action form validating the same field, what may causes some duplication and a harder maintenance. A central unit of validation and resetting suits this problem very well. The strtus validate stuff is centralized, and easier to configure. Doing it all in one class, means that at some point your going to have logic to handle special cases The more of these you have hte more complex the logic... Complex logic is directly related to the stability of your code. In addition I don't have to code the validations myself. Just specify what I want validated and I'm done. You could do the same thing, however you still have to glue it all together. - With this approach i can perform light business validation that must be done in java code. So, for one or more situation i could access some util classes that do some validation for me. You can do this with custom validation classes and still achieve centralizations. Depending on what you mean by light business validation. I like consistency in where things are. Business rules in business layer, and validation in the view tier. A newcomer to the app would have to guess (yeah, sure they'll ask, maybe) where the code is supposed to go. - With this approach i have very small action forms that basically has a validate and reset methods that just delegate to the WebValidation and WebReset classes.

In my JSP 1, which is home.jsp, I have this hyperlink (something is wrong with it): html:link forward=/RegisterRegister/html:link html:link action=/RegisterRegister/html:link However, upon further reflction... If what you really want is a href=/Register.doRegister/a generated, then you could do it with an action forward too. Which is what you tried to do above, you just need a global forward call /Register, or rather Register. The difference between the two? Not much in terms of basic functionality. Lots in terms of re=use. I tend to like the start of my use cases as global action forwards, that way I can change how to get into them action wise.

Re: ActionForm data type X BeanUtils - using Dates
I got one doubt in your code when used in a situation
that i mentioned (transforming data from action form
to dto).
When date comes from action form, they usually come in
Strings, but in your method you verify
value instanceof Date...
This will never happen, as the value comes in String.
Am i saying something stupid???
I'm not saying your code is wrong, but not appropriate
for the situation in question.
Am i right?
--- Bryce Fischer [EMAIL PROTECTED]
escreveu:
The custom converter is done independently of the
action, form or DTO.
First step is to implement the interface
org.apache.commons.beanutils.Converter.
Keep in mind that the converter you are writing uses
the appropriate
converter for the original class. So, if you were
converting from a
String to a Date, you would create a String
converter. And vice versa,
if you were converting from a Date to a String you
would create a Date
converter. Example below
Then, to override the standard converters, you call:
ConvertUtils.register(Your converter class, class
to use converter
on.class);
First parameter is your new converter, and the
second is the class its
used for. I call this in a static initializer of a

just need to make sure its called before any

only needs to be done once.
Since we are interested in customizing conversions
from String to Date,
I override the String converter:

public Object convert(Class type, Object value) {

if (value != null) {
if (value instanceof Date){
returnObj =
dateFormatter.format((Date)value);

} else {

}
}
return returnObj;
}
}

setters, but I think
you get the gist of what I'm doing. Now, I register
this converter as such:
ConvertUtils.register(new StringConverter(),

I actually have a utility class, where the register

to use a servlet that
loads prior to Struts.. Or if your Actions have a

Moving a data object into a map inside a form?
Hi I've got a custom javabean that I want to move all of its public properties directly into a map held in a form. I've tried BeanUtils.copyProperties(myMap, myObject); as well as PropertyUtils.copyProperties(myMap, myObject); neither seem to do what I want, however if I reverse it for moving data from the map to my object it works great. I swear at one point I had it working doing this but then it conked out.. (dont ask I dont know either :P). Anyway is there an easy quick way to move everything from my object into a map?

RE: ActionForm data type X BeanUtils - using Dates
I was taking a look at bean utils source and could see
myself how this is done. Then i understood that
acutally you use the
value instanceof SOMETHING
However, the BeanUtilsBean class is quite complex and
i didn't have the patience (and the brains) to try to
understand it.
Anyway, it seems to me that when the value goes to
the convert method it already has a defined data type
(that's way the instanceof). But can anyone tell me
how exactly is the flux of data?? When does exactly my
value assumes the destination type???

Gracefully handling invalid paths
Hi all, I am wondering how I should handle invalid path situations within my Struts application. I want to be able to have a catch-all page whenever someone enters an invalid path so that they don't see that ugly Tomcat 404 page. How might I go about doing something like that? Thanks very much.

Re: Gracefully handling invalid paths
You can specify it in your web.xml: error-page error-code404/error-code location/error_404.jsp/location /error-page -Yves- On Wed, 8 Sep 2004 20:36:38 -0700 (PDT), Andy Engle [EMAIL PROTECTED] wrote: Hi all, I am wondering how I should handle invalid path situations within my Struts application.

{
values.put(attachment,url);
}
public Object getValue(String attachment)
{
return values.get(attachment);
}
public void reset(ActionMapping mapping,HttpServletRequest request)
{
values = new Hashtable();
}
/**
* @return Returns the linkVal.
