[OT] Is it possible to use commons-el in a standalone application?
Hi, I know this is an off-topic message, but as many people here works with Jakarta Commons components, i decided to start my search in this list. I was thinking about writing a Swing app where its config file would be a XML file. And i'd like to put EL expressions in that file. So, my question is: is it possible to embed EL into a standalone app? I was reading commons-el API docs and they make a lot of references to JSP implementation classes (PageContext, VariableResolver, etc). So, in first glance, looks it is not possible. Is my conclusion right? Thanks in advance for any hint. Regards, Daniel Silva. __ Do you Yahoo!? Yahoo! Finance Tax Center - File online.

RE: [Suggestion] struts-user-newbie list
Hi Andrew, Good point. Freedom of choice is very appreciated and is one the axioms of open-source community ;-) By the way, I'd like to invite all newbies and even Struts gurus to join us at #struts_users IRC channel at irc.darkmyst.org. There you can get help and meet some of the coolest guys in Struts world (myself included ;-)). You can, at least, have fun there! Cheers, Daniel Silva. --- Andrew Petro [EMAIL PROTECTED] wrote: My hope was that differentiating the lists Struts might make the email load more tractable for everyone. Struts gurus might very well look at a new list for newbies and choose not to subscribe. I don't see this as a problem. Struts gurus helping newbies is a wonderful thing, but we're all volunteers here and if the gurus would prefer not to be on the newbie list, they should be empowered to make that decision. It is true that differentiating the lists might lower the threshold for newbie effort prior to newbie posts. However, the existing infrastructure for encouraging everyone to think, read, Google, etc. before posting would still be in place and could apply equally to the struts-user-newbies list. However, separating out a newbies list would allow newbies to helped by those Struts gurus who are most generous, patient, or have whatever other attributes that make them want to help newbies, while not annoying other Struts subscribers who are less interested in this. This accommodation might help to preserve the friendly and supportive character of the list for newbies even as Struts continues to grow. What I think differentiating the lists would do is empower subscribers to separate out the two streams and manage them independently. It feels to me like there really are two simultaneous streams of messages on this list. When things get crazy at work I could choose to fail to keep up with the struts-user-newbie list and delete the messages unread without feeling that I was risking something I'd need to know. Or, for that matter, when things get crazy at work I could choose to come home and see if there's someone to be helped out on the struts-user-newbie list, letting the more demanding struts-user material go until things settle down again. I don't know for sure how people would use the ability to differentiate, but I think volume on the list is sufficient that it would be worth giving subscribers this ability.

Re: struts and ibatis
Kelly, After looking for good options to make my applications simple, i found iBATIS. It is a very nice piece of software and, in my opinion, based on experiences, it is ready to go to a production environment. I used iBATS DB Layer and SQL Maps in two projects and it did very well. New 2.0 version has amazing features. It is still in beta stage. But i'm sure being in beta is not worse than Windows + SP1000. In fact, i trust more in iBATIS beta than in any M$ 'production' software as you have access to the code and if you find a bug you can fix it. If you'd like to know more experiences about iBATIS join us at #struts_users IRC channel on irc.darkmyst.org. Other cool resource for iBATIS newbies is Rick Reumann's iBATIS lesson (www.reumann.net). A simple and useful app showing how to use iBATIS. Hope i helped you. Cheers, Daniel Silva. --- Kelly Goedert [EMAIL PROTECTED] wrote: It helps mapping between the application and database.

Proper use of ProcessAction, ProcessResult and ResultList
Dear Struts users:
For a couple of weeks now, I've been trying to use the ProcessAction class
in Struts Scaffold, following the book Struts in Action and the example
Artimus application in which it was demonstrated. It's pretty convenient in
that it simplifies the design of my business logic classes, making them
completely reusable outside of Struts or even a web app.
I just have a number of issues with it that I haven't resolved, despite
having stepped through the source code and closely studying the Artimus app:
1. How do you display a confirmation message when, say, a record was
successfully saved? I use a ProcessResult to wrap the results, and there is
a method ProcessResult.addMessage() which seems to allow you to add a
message to it. Here is the snippet of code...
start of Java code snippet --
...
UserManager manager = getUserManager();
List users = manager.getAllUsers();
ResultList resultList = new ResultListBase(users);
result = new ProcessResultBase(resultList);
if (resultList.getSize() 0) {
result.addMessage(users.found);
result.addMessage(new Integer(resultList.getSize()));
} else {
result.addMessage(users.none.found);
}
result.setDispatch(success);
end of Java code snippet --
and here is the JSP fragment that attempts to display the message...
start of JSP fragment -
...
logic:messagesPresent
UL
html:messages id=error
LIbean:write name=error//LI
/html:messages
/UL
/logic:messagesPresent
logic:messagesPresent message=true
UL
html:messages id=message
LIbean:write name=message//LI
/html:messages
/UL
/logic:messagesPresent
...
end of JSP fragment -
This is a verbatim copy of the message.jsp in the example Artimus
application. However, when I hit the page, an exception is thrown with the
message could not find bean message...
END OF FIRST ISSUE
==
2. How do you set a transactional token? From the code in ProcessAction (at
the very end of the preProcess() method), it appears that I have to define a
forward whose name is stored in Tokens.SET_TOKEN for a token to be set.
Does this mean that I have to define a local forward for each data entry
form that I need to guard against multiple submissions?
END OF SECOND ISSUE
=
I hope I've explained the issues above clearly. I've been looking at this
for two weeks, searching through the archives for answers without much
success. I hope that with this post, someone can give me some clues as to
where to look.
Thank you very much, and a Happy New Year to all!

Jerald, The first parameter to ActionMessages.add() is a string interpreted to be either ActionMessages.GLOBAL_MESSAGE or a name of one of your form fields. If you had a field on your form that was named (i.e. property=...) username, then if you wished to add a message pertaining to this field, then you would write: messages.add(username, errorMsg).

Re: How find DataSource?
Wow, my personal saga of discovery continues... Apparently I have been trying to set up connection pooling *both* in server.xml context *and* in web.xml unnecessarily. Well, the server.xml works, but then I have the problem of where to store the DataStore object and how my Data Access Objects will access it. Has anyone set up a connection pool using web.xml? Steps? Examples? Tips? I can't even seem to change the driver without problems. And, web.xml doesn't use JNDI, does it? Has anyone used server.xml instead? Where did you keep the DataSource Object? I looked into keeping it in the session, but then I have to pass session to my DAOs--ick. (I am writing my own DAOs.) Vic, I might have two problems with keeping it in a static block. 1. My container can be passivated, so everything must be serializable. 2. I hope to only look it up once for efficiency's sake.

DOTs, wild cards, and action mapping
I started using the wild-card support in action mappings (from a CVS
build). It works, but I noticed something strange (until I realized
what it was doing). So, I have a action mapping like:
action
path=/areas/*
type=apackage.AreaAction
forward name=success path=.area/
/action
Then in some jsp I have:
html:link title=${area.name} action=/areas/${area.address}
Where area.address expands to '10.0.0.1'. Struts will look for the last
dot in an action and chop it off. So I keep getting a string like:
a href=/managearea/do/areas/10.0.0 title=area1area1/a
So I am not using extensions in my struts configuration and I would
intuitively think that I would get '10.0.0.1' back. Is this an
ambiguity that appeared with the new wildcard support that cannot be
resolved (meaning I should never use '.' in any names) or is there some
way to resolve this? Perhaps I must always use extensions to combat
this (i.e. action=/areas/${area.address}.bogus_extension - which is
fine by me as a workaround)?

RE: Please help with this error ???en_US.errors.required???
Hi Vivien,
I think it depends on Struts version you are using. I use 1.1 and everything works
fine.
Your message-resources/ config tells Struts to look for your resources at package
org.apache.struts.webapp.tiles.dev1-1. So, you should have, for instance, this:
WEB-INF
--
|
|--- classes
--
|
|--- org/apache/struts/webapp/tiles/dev1-1
|
| - ApplicationResources.properties
If you are not using 1.1, please, upgrade to. If problem still happens, you know how
to find us.
Hope it was useful.

Daniel.

Take a look at your web.xml. Maybe you copied it from Struts dist and
message-resources was
already configured there. As settings in web.xml will override settings in
struts-config.xml,
classloader can't find resource to be loaded and then you get that messages.
Hope i helped you.
Kind regards,
Daniel.

Re: [OT] [Reflection/Classes] doing something like instanceof at runtime
Andrew,
I don't know if this is the best way, but you can try something like that:
boolean isInstanceOf(Object o, String klass) {
Class c = null;
try {
c = Class.forName(klass);
} catch (ClassNotFoundException e) {
// TODO
}
return c.isInstance(o);
}

RE: bean:write property= Format a Date ?
Hi Mahalkar,
You can use JSTL to do that work on your JSP page. Just use formatting standard tags.
As Mark said, it is piece of cake.
You can use:
fmt:formatDate value={$my_property} pattern=my_pattern/
Formatting pattern is exactly the same as patterns used in SimpleDateFormat.
Look at JSTL reference docs to more details.

Daniel Silva

I don't thing struts provide you formating date functionality as i never
tried also but frankly it will take another 20 min. to write a function for
formatting date..
use string.substring methods and all after retriving the date from DB using
getStirng()
or use to_char(datefield,'dd/mm/ hh24:mi:ss') or any other format u
want. and if you are working with Java Date class then calculate the long
value of that with
String s = date.getDay()+/+ getMonth()+/getYear() functions it's really
simple...

The Javascript checking generated by the Validator framework doesn't give an error if neither on is selected, however the backend will, and produce an error I can see with the html:errors tag.

nested:iterate rendering fails
Hi all, I have a form with a nested bean. That bean contains a collection I'm trying to iterate with indexed properties. I tried first doing this without the nested tags but had no success. (The page displayed but instead of myForm.nestedBean.element[0].property, I only got element[0].property.) I did add the extra getter and setter to the nestedBean, but I guess Struts expects it to be on the form. I then tried the nested tags based on this post: http://marc.theaimsgroup.com/?l=struts-user http://marc.theaimsgroup.com/?l=struts-userm=105364604308495w=2 m=105364604308495w=2. This seemed promising, but the page won't even render. The relevant part of the stack trace is at the end of this message. My jsp code looks like this: nested:nest property=clientDoc nested:iterate property=defects /tr ... td nested:text property=statusEffectiveDate/ /td /tr /nested:iterate /nested:nest clientDoc is the bean on the form. defects is a collection on the form. statusEffectiveDate is a property of each element in the defects collection. I ran the debugger and can see that NestedIterateTag's property property is set to clientDoc.defects, which seems reasonable, and originalProperty is set to defects. Some attr is trying to be looked up, but it's name is null.

Writing Javascript for Validators
Hello All, I've written a new plugable validator rule, and now I'd like to write some javascript for it. Looking at the existing javascript for other validators, I see they all make a call like this: oRequired = new required(); which (in this case) gets all the required fields. I'm not sure what generates this method, but I can see it in my jsp when i put in html:javascript. my new rule is called futuredate. I don't know what sort of method I should call that will be like required(); but give me all the fields marked with furuterdate. How do I do this? Cheers __ Do you Yahoo!? Yahoo!

Re: Writing Javascript for Validators
Robert,
Warning, I haven't done this before, but need to :
The validator-rules.xml and validator.xml file for
your project have the
same format.
In --your-- validator.xml you can enter:
form-validation
global
validator name=futuredate
classname=com.matte.futuredate.validator.FieldChecks
method=validateFutureDate
methodParams=java.lang.Object,
org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionErrors,
javax.servlet.http.HttpServletRequest
msg=errors.required
javascript![CDATA[
function validateFutureDate(form) {
...Your code
}
]]
/javascript
/validator
/global
My question is this. In that Javascript code, I need
to validate the fields. How do I know what fields
need to validated? The javascript methods provided by
Struts for the other validators seem to call a method
that builds an array of all the fields in the form to
check, and then do a loop over that array.
(for example, the required validator makes a call to a
method called required()).
My question is what call should I be making? I don't
know how the required() method is being generated (it
isn't in the validation-rules.xml file, but it appears
in the code included by html:javascript. I'm going to
need something like a futuredate() method that builds
this array, but I don't know where I need to write it
(or how I tell struts to build it for me).
Does this make sense?
Cheers

Re: struts 1.1 question
From the article at link below Direct Requests to JSPs To take the full advantage of sub-application support, Struts 1.1 stipulates the requirement that all requests must flow through the controller servlet, i.e. the ActionServlet. Effectively, this means all JSPs must be fronted by Actions. Instead of allowing direct requests to any of the JSPs, all requests must go through an Action and let the Action forward to the appropriate JSP. This is perhaps the biggest impact of migration to Struts 1.1 if you have not followed this idiom in your applications. This restriction is required because without going through the ActionServlet, Struts navigation taglibs (e.g. html:form and html:link) used in the JSPs will not have the correct sub-app context to work with. http://www.theserverside.com/resources/article.jsp?l=Struts1_1 At 8/11/2003 04:48 PM, you wrote: Where exactly did you read that all jsps must be fronted by actions?

I guess it just seems like extra work that doesn't yield obvious benefits, not unlike having to do all those getters/setters in 1.0, but I guess if I had to choose between the two, I'd choose this.

You need a lot of pages even without Struts if your site has a lot of content. You don't have any extra JSP pages because of it but it makes you Struts config file a little longer than if you didn't have to map all your JSPs. But then that (config file size) is one reason you can break down your struts config into multiple files per module. Goes back to a point I made last week that config info might be better served in say the LDAP compared to a flat file. Unless the framework is willing to do inefficient constant file reads to get the actions mappings then it means all the Struts config info has to be loaded into memory. If you site has 1 mappings could you imagine the memory usage? But the LDAP is made for fast reads, perfect for something which doesn't change much, like config information.

You can do this way:

fmt:formatNumber value=${your_property} type=currency/

Form Bean Help?
Hello All, I'm running into a little problem, maybe someone can help me fix it. My application is driven by filling out web forms. At one point, A user can click the Save Form button, which writes the form information to a Database. When the user visits the page again, the action builds a DTO that contains all the information they had filled out and puts it in the session scope, then forwards to the JSP page that has the form on it. I had been using the value property of the struts-html tags to fill in the data, but I've noticed that when the user hits submit, if there is a validation error, they are pushed back to the page, and the data they had enetered is replaced with what was in the DTO (which is now old data). I've also run into the problem of filling in things like radio buttons, based on what was in the DTO. It seems to me that what I want to do is not pass along the DTO with the action, but fill out parts of the Form Bean before forwarding to the page that displays it, at which point I could remove the value properties of the html tags, and have everything work. My question is, how can I do this from the action? Or do I want to attack this problem in another way? Thanks! __ Do you Yahoo!? Yahoo!

Questions are: How should I implement the above project (using Java technology) with regard to should I use struts or not? What will be the benefits of each approach-with or without struts? With regard to ease of implementation, because I'm new to web application, which one will be easier-with or without struts (for a newbie-r)? why? However, I'm tempted to use struts. When I use struts, what simple steps should I do to finish the project? Are there similar examples (using struts) found at the Net that I can cusomize to my purpose? In this case, I'm going to use MySQL as database engine.

Subject: Converting an ActionError to a string programmatically
Hi all.
I am looking for a good way to turn an ActionError into a string, without
having a
PageContext or anything else so useful (so I can't use the
RequestUtils.message()
function).
Is there a simple way to do this? I can probably do it the hard way, by
digging
through the RequestUtils source and working out what it does, but I'm hoping
that
either (a) there is another utility class I've missed that will do this, or
(b)
someone else has done this and can save me the pain!
The reason I need this is that I have some code that updates a back-end
system, and
returns ActionErrors if there are any validation failures. Usually this
gets called
from a struts action, and the errors get displayed to the user with the
errors/
tag.
However, now we need to do some background batch updates, called from a
thread
spawned from a servlet (which is outside our normal struts pages). The
batch process
is likely to be slow, and so we want the results of any validation failures
to get
logged to an error file, rather than getting displayed to the user.
Any suggestions?

Struts Taglib DTD's and Firewalls

Passing Information with forward
Hello All. I'm running up a problem and I'm not sure how to solve it. In my application, there is an action called PLAReview. An e-mail is sent to someone telling them to click on a link that looks like this: http://www.whatever.com/PLAReview.do?id=1 The Action PLAReview uses that ID number to pull some data out of a database, push it into a DTO, put the DTO in the request scope, and then calls mapping.findForward(Success); which forwards to another jsp page. This page prints out all the data from the DTO, and also has a few form feilds that the user needs to complete, and then submit. I'm rendering a html:hidden object on this second page, that will hold the id of this request (the same ID value from above), but I don't know how to get it there. I tried doing: html:hidden property=id/ But that didn't seem to work because I think it wants to get the ID property from the ActionForm object tied to the form, which doesn't have the correct value. I need a way to get that value from the first URL, and also make sure that if validation fails and the form is redisplayed, the value for ID is pulled from the ActionForm (since I think the initial id from the first URL will be lost). Does this make any sense? Cheers! __ Do you Yahoo!? SBC Yahoo!

RE: Does a degree matter?
Hi all, Just my two cents. Craig's viewpoint is good for american-like degrees. But there are many different education systems all over the world. For example, in my country (Brazil), Comp Sci bachelor's degree from public universities don't teach nothing more than old theory. We study Automata theory, Graph theory, Calculus, Algebra, Physics, Statistics and Algorithms as course basis and we have specialized disciplines where we study more specific theory like: DataBases theory, Operating Systems theory, Programming Language theory, Compilers theory, Data transmission, Computer Networks, Computer Networks Management, Artificial Intelligence, Functional programming, Logic programming, Object-Oriented programming, Object-Oriented analysis, Project management, etc. And at my university (University of Brasilia) we have to take some optional (not so much) courses to get our degree. They are: Management, Accounting, Economics, Sports, Political science, Philosophy, English, Operational research, Law science etc. Our professors don't teach programming languages like Java, C, Pascal, Lisp, Prolog, FORTRAN. They delegate this task to students. I think it is a hard course but it's worth it.

Brandon, If you can do the deed (which it sounds like you can), I would hazard offering my opinion in thinking that it wouldn't be the best use of your time. By education I'm a graphic designer, not a computer scientist. First job was web design, programmer ever since. Results... I've only had two places not take me on because it's not a computer degree. Two interviews of hundreds. My personal experience (both for myself and for folks I have hired over the years) mirrors this -- indeed, my personal opinion is that a Comp Sci degree is worth less (to me as an employer) than a degree in some field that is more closely associated with the general needs of potential employers. Why? A couple of reasons: * Many folks who go for Comp Sci degrees obsess over learning the particular technologies being taught in their classes, at the expense of courses to improve your general thinking skills. Any specific technology you learn in your first year is going to be totally obsolete by the time you graduate from the program anyway, so why bother? The important skill to employers (at least from my viewpoint) is that you've learned how to quickly adapt your existing skills to new technologies as they become available. Also, the fundamentals of good architecture and design practices tend to change much more slowly than the favorite language de jour -- so if you decide to go for Comp Sci, focus on fundamentals like O-O, design patterns, and so on. * Many folks who go for Comp Sci degrees are so focused on the technical things, and don't accumulate any domain knowledge along the way that would make you *more* valuable to potential employers than another Comp Sci graduate with similar skills. If you're building e-commerce systems, do you know anything about the fundamental accounting principles involved in tracking purchases? If you're building systems to introduce novices to the world of online information, have you ever studied any human factors engineering? If you're building trading systems for a Wall Street broker, do you have the slightest idea how stock and commodity exchanges work? It may surprise some of you to find out that I don't have a Comp Sci degree at all -- instead, I got a BA in Business with a focus on Accounting. This was ***tremendously*** helpful in setting me apart from everyone else who was learning programming and systems analysis in those days -- I could immediately communicate with the end users responsible for the systems we were building, using their vocabulary, without having to be trained -- in addition to the fact that I was a fair-to-middlin' programmer
requiredif and null
Hi all, I'm doing validation on a form where I have 3 dependent fields. If any one is present, they all must be present. I set-up my validation by saying A depends on B depends on C depends on A. I know this worked at one time. Currently I'm using 1.1 rc1 and previously was using 1.1 b3. I don't know when this stopped working. While stepping though the jsp generation with a debugger, I can see that value= is being written even when the form values are null. The server-side validation then sees empty strings instead of nulls, so my validation doesn't work. BaseFieldTag.doStartTag() is automatically writing empty strings instead of nulls. Should I take a completely different approach? thanks john john gregg Wells Fargo Services Company Minneapolis, MN
trimming fields in bean and html tags
Hi all, I'm forced to live with a db where many columns are chars instead of varchars. In cases where the contents of the char column doesn't fill the space allowed, I get my result padded with spaces. The practical problem that this introduces is that if I want to use the validator to enforce length restrictions (where the max length is the db column width), a user can't just put his cursor at the end of the visible text and start typing because of all the spaces.

Hi, I have a bean class that returns an ArrayList of ArrayLists for my

bean class:
public class UserAccessBean implements java.io.Serializable {
List deptList = new ArrayList();
List brokerList = new ArrayList();
List filters = new ArrayList();
public List getFilters() {
deptList.add(new LabelValueBean(1, Department1));

brokerList.add(new LabelValueBean(broker1, BrokerDepartment1));

brokerList.add(new LabelValueBean(broker3, BrokerDepartment3));
filters.add(deptList);
filters.add(brokerList);
return filters;
}
}
The 'filters' ArrayList can actually return 2 or more ArrayList. Like if
there's 3 ArrayLists, I would like an html output such as:

Re: ActionServlet Action caching problem
My execute/perform methods aren't normally synchronized. The javadocs don't indicate they expect it to be, so, calls to that methods shouldn't get blocked. However, you could have concurrency problems if you're using static, class, or instance variables. The execute/perform method should limit itself to using local variables or data passed by reference and you won't have this problem. Unless you explicitly declare some class methods synchronized, in which case you're exactly right. If you do that, however, you ought to mean to produce that effect and limit your critical section to a small block of code-- ideally one that doesn't block on anything. ;-) Maybe I'm out to lunch, though.

Re: ActionServlet Action caching problem
I've had problems with references to beans on instance variables in an Action object getting stale. I'm on Jboss and in my experience the stale references hork a nice fat RMI exception. Can you turn debug logging on in your execute / perform method and see if that's ever getting called? In my case, it always was. My issue relates to Action objects hanging around after a session bean has been removed or passivated by the EJB container. It would be really nice if someone decided to implement a timeout on the Action objects so that if they were older than a certain age, they wouldn't be used. Don't know if we're seeing the same behavior from different angles or not. ciao, -nash On Monday, March 10, 2003, at 04:07 PM, Whitmire, Jeffrey wrote: I've got a weird one. I'm hoping that somebody else has encountered this before and can help. We are in the midst of load testing our app before rolling it out to production. I have one action class (only one) that starts failing well over an hour into the test. It appears that the instance of that action class cached by the ActionServlet becomes invalid. I can see no reason why the change in behaviour, but at some point the RequestProcessor gets an instance to the Action that is no longer valid. It is not null, but it never executes it. The rest of the app works perfectly, but that button (tied to that specific Action) never works again until the tomcat instance is restarted. It just hangs, and the last indication in the log is the RequestProcessor finding and returning an instance of that action class. Has anyone ever had problems with Action instances going stale? or some other config problem that could cause this?

Re: dynamic generated controls
I've used code like this in my Action class execute/perform method:
String inputs[] = request.getParameterValues(s);
for (int x = 0; x inputs.length; x++) {
String oneInput = inputs[x];
dosomething(oneInput);
}
This seems to work quite well, assuming all the form input tags are
named the same. I don't know struts well enough, yet, to know whether
you can have an ActionForm property be a Collection type, or not. Would
be interested in the answer, though. It wouldn't have mattered in my
application, though, as I needed to generate an entire form
dynamically, so it would have been a wash, either way.

Re: [OT]: Struts, Web Development, J2EE, and what is too much?
I use Jboss. It works quite well with struts. EJBs have made my application EASIER and LESS complex for me, but I don't know any SQL or database technologies at all. If you're comfortable with managing your own database widgets, you may be frustrated with how slow J2EE is on your hardware and you may also be frustrated you can't access some of the more advanced functions easily. Performance is an issue as you pay mad overhead for the RMI stuff in J2EE. Much slower than native JDBC. If you can afford to upgrade your hardware, you may benefit. YMMV, but, I like it. I'm just using struts for presentation. -nash On Monday, March 10, 2003, at 05:41 PM, David Graham wrote: I've never used EJBs but Struts doesn't need to know about them at all.

Date: Mon, 10 Mar 2003 14:34:45 -0800 I know this question has probably been asked before, and that biased publications have had their opinions on it, but I wanted to get some feedback regarding some real user experience regarding the use of EJB in a web application used along with Struts. I am creating a web application and I have decided to use struts. The application needs to be high performance, uses a single database (so it doesn't have heterogeneous transactional db requirements). I have designed the application in layers, and it will only have a web interface. It's starting small, but will grow to have many functions. Even though I'm confident that I need not invest in EJB's, I don't want to develop the application to find out I should have used them (hence why I'm creating this post). In what scenarios have people found the use of EJB beneficial? When have they been overkill? Does struts integrate smoothly with EJBs? My fear is that I'll make the application overly complex by implementing EJBs, but I'd like to hear from people with experience building large web-only projects with struts.

RE: [OT] Which Object Relational mapping tool?
Hi Jacob, You did a good point. I am working on a project and was in doubt about what use: pure JDBC, DB Layer from iBatis or a real O/R mapping tool. I tested OJB, it is a great piece of software. Looked at Hibernate, it seems like a good choice. I tested also Torque, what is as good as others. But, to my project i have choosed DB Layer from iBatis. But i am doing some customizations on it. I am adpating it to use Jakarta Commons BeanUtils and, thanks to that, extending ResultMap elements to enable dynamic ResultMaps using DynaBeans since there are moments where you can't write 50 classes only to hold your results, or, you are lazy enough to write it. When i finish that modifications i will submit then to Clinton Begin, iBatis author, to receive his agreement about that. If you have any cool suggestion about iBatis DB Layer, i'd like to hear it from you. Best regards, Daniel Silva. --- Jacob Hookom [EMAIL PROTECTED] wrote: In my opinion, this topic is just fine-- it comes up every week :-) I personally dislike O/R mappers because in most cases, I completely agree that beans and db should be separated, but it's at the point of merger that things get overly complex at the expense of an additional layer that needs just as much configuring as writing your sql code for each use case. For example, with O/R, you have an ArticleHeader that has ArticlePage(s). You are actually storing the page content in the DB for various reasons. If you are using OJB with the goal of getting the number of pages the article has, in most cases, you are ending up selecting 1000+% of what you REALLY need from the DB: --- OJB: SELECT ArticleHeader key Check cache SELECT ArticleHeader and SELECT ArticlePage keys Cache it Call getPages() on ArticleHeaderBean SELECT each ArticlePage where cached key = DB key while checking the cache before EACH SELECT to ArticlePage table for EACH Row Builds collection of ArticlePages (including all of that page content) Call getSize() Vs. SELECT COUNT(key) FROM ... I guess I really can't reason the practicality of it. On the other hand, the ibatis.com db layer is VERY cool because it allows you to look at your use cases and write a select statement that can be executed; much like the way struts has actions. I get the bonus of caching objects with O/R mappers, but site performance is much better by caching the resulting output (the view itself) in most cases.

tokens and set-property
I'd like to use the set-property element of struts-config to tell my action whether to expect a token. For example, I have an action like this: action path=blah... set-property property=useToken value=true/ /action I'm using an abstract action subclass that itself is a superclass to my real actions. It contains a boolean useToken property. I also tries a String but it didn't matter. That property never gets set to what I specify in the struts-config file. Any suggestions? thanks john john gregg Wells Fargo Services Company Minneapolis, MN

RE: Copying 'nested' properties from Dyna form to beans
I've tinkered with this, but there are definite limitations. I saw in Chuck
Cavaness' book where he put a value or domain object as the sole property
inside a form. In the JSPs he references it as form.bean.blahblahblah. I
thought this meant I wouldn't have to dumb-down my forms. Well, as you've
seen, BeanUtils.copyProperties() won't copy when it doesn't recognize the
target class. You can create a Converter to handle some of these
situations. I created an AbstractConverter class that has abstract
getToClass() and getFromClass() methods. My convert() implementation just
uses getToClass() to create an approriate target object (using
Class.newInstance()), then calls BeanUtils.copyProperties on it. For simple
situations, this works really well. However, there are some limitations.
First, you can't have circular references because there's no mechanism in
place to note whether the copying of a given object is already in progress.
You'll get a StackOverflowError. I think I know how to get around this but
it's pretty invasive. Second, you can't copy properties that are of the
same type as the containing object easily. You'd have to duplicate a lot
(all?) of the functionality of copyProperties(). Third, the contents of
collections are a problem because you won't know what type the contents of
the new collectin should be, unless you add some other facility for figuring
this out (like given value object type X, convert to domain object type Y.
This is the opposite of how the Converters work now.) Finally, if you're
copying from a persistent object that uses some form of pointer swizzling to
a value object, you've opened a whole new can of worms.
I don't know what my fallabck solution is exactly. I think I might pick a
few limitations and live with them for now.

Subject: Copying 'nested' properties from Dyna form to beans
What's the best way to copy 'nested' form property values to Java beans? For
example, let's say I a 'Person' bean, which contains a nested 'Name' bean,
like this:
class Name {
String getFirstName() {...}
void setFirstName(String firstName) {...}
String getLastName() {...}
void setLastName(String lastName) {...}
}
class Person {
Name getName() {...}
void setName(Name name) {...}
String getZip() {...}
void setZip(String zip) {...}
}
In the Person class, 'zip' is a top level property, but firstName and
lastName are nested properties of the name property. I'd like to set up my
validation.xml form element something like this:
form name=personForm
field property=name.firstName/
field property=name.lastName/
field property=zip/
/form
Or, can I / should I nest form elements?
Finally, what I'd like to do is use BeanUtils.copyProperties, or whatever,
to copy from the dyna bean to the Person bean:
BeanUtils.copyProperties(person, form);
It would be cool if copyProperties would know to copy the name.firstName
form element to person.getName().setFirstName(...).
What's the best way to do something like this, to copy 'nested' properties
transparently in one method call?
Thanks!
Steve

sematic validation
Hi all. I love the ability of Struts to perform syntactic validation of input data and automatically redisplay the screen + data + error messages. However, I'm reluctant to put semantic validation checks anywhere but the business objects to which they belong. For example, I have a rule that says an organization's effective date cannot be in the future. I consider that part of what it means to be an organization in my domain, therefore logical places to enforce the rule are either the appropriate setter or a preCommit() persistence callback method. However, when using something like BeanUtils to copy values from my value objects to my persistent domain objects, if an exception is thrown in the setter (or even later at commit() time), what's the best way to propagate that back to the user? BeanUtils will throw an exception as soon as the underlying setter throws one, regardless of whether there are further semantic validations (on other properties) to perform. I'd like it to appear to the user the same way as when the Struts validator flags a problem. thanks john gregg Wells Fargo Services Company Minneapolis, MN

null references in ActionForms
Hi all, I'm curious about why forms don't like null references. Let's say I have a form with a ref to a domain class that I wrote. That class has a name attribute. Struts complains when it tries to reference someForm.someClass.name if someClass is null. In the case of displaying an entry page for the first time, if someForm.someClass is null, Struts I think should either ignore it, as it would if someForm.someClass.name were null, or it should call the default constructor and go from there. Why does it not do this? Can it be configured to do so? Is there an alternative? I see FormPropertyConfig but it only applies to DynaForms. For now I've tweaked my getters to return a new instance if the ref is null, but I'm uncomfortable with this. thanks john john gregg Wells Fargo Services Company Minneapolis, MN
