Re: banned
Few mature individuals who are well-grounded in a spiritual sense have any fear of what newcomers and troublemakers can do to reputation or to effectiveness. Those who yell, those who take up space, those who talk strange and even with evil in their hearts, those who are burdened with mental twists, those who rebel, and those who trade on the list's reputation, all such people seldom harm at all and, if at all, not for long. Some of these will become our best and most respected list members, if not a part of the holy table of committers. Some leave, some remain to try our patience. Others seem to just drift away. The troublemakers should be regarded not as menaces but as our teachers. They oblige us to cultivate patience, tolerance, and some humility. If they are sick, they are only sicker than us at worst. Those that openly condemn them are the Pharisees whose false righteousness does the list more and deeper damage. Some of these are, as is usual in such matters, our elder statesmen. I am very sorry you lost your job, Mark. I cannot imagine this is likely to better you. But, please know that there are out here people who do understand that however sick or outrageous you might be, you deserve your dignity too. I wish that did not sound so high-and-mighty, and that is what Craig, for reasons only he can explain, finds so objectionable about me, I guess. But, this is a time, I think, to be high-and-mighty.

Re: RE: Question re html:select on the client
You can use the following code to dynamically generate the action where the
submit is to happen.
function linkEditClick()
{
document.formName.action=/editAction?id= +
document.formName.comboName.value;
document.formName.submit();
}
function linkAddClick()
{
document.formName.action=/addAction?id= + document.formName.comboName.value;
document.formName.submit();
}
function linkDeleteClick()
{
document.formName.action=/deleteAction?id= +
document.formName.comboName.value;
document.formName.submit();
}
these functions can be called on the onclick event of the respective links.

Subject: Question re html:select on the client
Hello,
I have an html:select populated from a collection. Alongside the select box
I have links to add, edit and delete items. I'm just wondering what the best
way is to handle passing the ID of the selected item to the edit and delete
actions.
For example, if the user selects the option with value 12, I'd like to
forward to something like /editAction?id=12. Is there some way to tell the
html:link tag to dynamically construct the querystring on the client?
Thanks,
Kent

I haven't heard about the tool for converting an application. Though, if you wanted to run a ASP.NET application on a Linux box, the open source Mono platform does that out of the box. In terms of processing speed, it's really very, very hard to come up with relevant benchmarks. Benchmarks are like bikinis or speedos; they seem to reveal a lot, but all the best bits are covered up. If anyone is truly concerned with processing speed, the only way to tell for sure is to code a representative part of your application with each choice, and then compare the two, head to head, on your own hardware on your own network. If someone doesn't care enough to do this, then they really don't care, and you can just flip a coin. It's usually not a difference that makes a difference anyway. In terms of development speed, C# and Java are very much alike, and the core ASP.NET/ADO libraries are very much like the J2SE equivalents. ASP.NET comes bundled with some components that make use of a built-in request-processing cycle, not unllike Struts, but all the usual suspects, like Request and Session, are there too. A great number of our favorite Java libraries are an easy port to C#, and have found a welcome home with C# developers. Apache Logging is a run-away favorite right now, along with NAnt. Other libraries like Lucene.NET, iBATIS.NET, and Spring.NET are also gaining acceptance. In my own work, I use the Resharper IDEA plugin, the Anhk Subversion plugin, and MySQL for the database, along with iBATIS.NET and Spring.NET. I really don't feel like I've changed environments at all :) Most ASP.NET teams also use a visual editor, like Visual Studio, to design the pages. Visual editors, regardless of what platform you use, tend to be a faster way to *create* pages, but a slower way to *maintain* pages. But, if you are in a fixed-cost, waterfall-design environment, shipping the pages quickly can be the primary concern. If client wants to make changes later, they can update the design docs and pay for a new page. This approach does work for many people (though not so much for me). There is a *huge* difference in programming styles between ASP.NET and Java teams. The most obvious difference is the attitude toward stored procedures. Most Java developers only use stored procedures if they must. Most .NET developers only use stored procedures :) One reason people tend to disagree over these things is that they want to compare apples and oranges. If you are working in a fixed-cost, waterfall design environment, then cranking out pages quickly with stored procedures and a visual editor is the way to go. And, if client changes the requirements, then it's back to the drawing board. OTOH, if you are working on an open-ended, agile design environment, and you want to be able to write code that you can test and refactor over time, then a visual editor is not going to be much help. While there will always been a difference between waterfall teams and agile teams, eventually, I think the differences between the platforms will become less and less stark. Which is a good thing.

For the record, I'm not against an employer firing an employee for 'whatever' reason they deem fit. If they don't like the way you wear your hair, I think they should have the right to fire you if they want. (The public also has a right to know about it based on the use of the press etc). Now though I'm clearly not in the position to get fired anytime soon, I still think as long as I'm doing my job right and don't blame the company I work for, what I do in my leisure time is not my employer's business. Including my haircut, age, religious beliefs or whatever. What I sell are my skills, work performance and last but not least a significant part of my lifetime, but neither my soul nor my private life. In Germany, it's not quite that easy to get rid of someone who, lets say, just got older because of working for you. And I think this is just. Stealing silver spoons, including deliberately breaking company rules in terms of e-mail usage and the like is another issue. Personally, if I owned a company and someone was using the company email domain name to post on sites such as swingers or transvestitepride, I think I should have right to terminate his or her's employment. What I have a problem with is ... 1) The inconsistency in what is protected. For example everyone today talks about tolerance. But what does this mean? What it ends up meaning is There are no moral absolutes so the only valid belief system protected is one that doesn't espouse moral judgments. But what about being tolerant to the idea that someone might feel otherwise? Why is state sanctioned secularism the only valid religion (and yes secularism is a belief system - a religion). It's sort of funny that those whom often claim to be the most 'tolerant' are often the most vicious when it comes to attacking someone that disagrees with their view of tolerance. There are many views I could state that would get me labeled as being 'intolerant,' yet, somehow it's supposedly not offensive to state All views on X,Y,orZ are equally acceptable. To me, and many others, that later position can be considered extremely offensive. Why is only one view (secular humanism) considered 'non offensive' but other religious views are some how bigoted and intolerant. It's pure hypocrisy. In Germany, in a major part thanks to the US (I mean it!), religious freedom, for instance, is granted to everyone in our Constitutional Law (Art. 4 GG). Getting fired just because of one's religious views is impossible by law.

[OT] FYI Ugly Tomcat Bug
Hi, after 3 hours of searching and debuging I just discovered an ugly tomcat bug and wanted to provide this information in case someone else is suffering from a similar behaviour too. init-param param-nametrimSpaces/param-name param-valuetrue/param-value /init-param This parameter in the definition of the JSPServlet in the web.xml can have a very ugly behaviour: The page in question is a simple container for different tiles: logic:iterate name=elements type=...ProfileElementBean id=element logic:notEqual name=element property=decorator value=none bean:define toScope=page id=_decorator type=java.lang.Stringprofiles.decorator.edit.bean:write name=element property=decorator//bean:define bean:define toScope=request id=_element type=.ProfileElementBean name=element/ tiles:insert definition=%=_decorator% flush=false / /logic:notEqual /logic:iterate So the page just iterates over a list of elements and inserts a proper decorator (a tile) for each of the elements. One of the decorators in question looks like: %@ page contentType=text/html;charset=iso-8859-1 session=true %jsp:include page=/do/prfEditDatasafe flush=false/ so it includes an action. Now after the iterate passes over this decorator it crashes in the logic.iterate tag (unfortunately without stack trace, but we was able to find with debug output that it's the end of the iteration, where it crashes), the only output is: 2005-07-07 14:40:15 ApplicationDispatcher[/dating] Servlet.service() for servlet jsp threw exception java.lang.NullPointerException Unfortunately, after this, the tomcat is totally screwed up. Nearly any other request ends with: 005-07-07 14:40:15 ApplicationDispatcher[/dating] Servlet.service() for servlet jsp threw exception java.io.IOException: Stream closed at org.apache.jasper.runtime.BodyContentImpl.ensureOpen(BodyContentImpl.java:576) at org.apache.jasper.runtime.BodyContentImpl.write(BodyContentImpl.java:140) at org.apache.jasper.runtime.BodyContentImpl.write(BodyContentImpl.java:157) ... There is also no possibility to catch the error somewhere else (and we tried every line in every jsp :-)) Since the code works fine with resin we assume that it's a tomcat bug :-) we are using tomcat 5.0.25 (but the bug is reproduceable in all 5.0.x versions) and struts 1.1 regards Leon P.S.

Tomcat5.exe Holds Onto Struts.jar
Hi: Perhaps this is a Tomcat question but it applies only to Struts. I have Tomcat 5.5 running under Windows 2000 with Eclipse as the IDE. Ant is used to assemble, compile and deploy the applications. However, the process Tomcat5.exe accesses the struts.jar at /WEB-INF/lib/struts.jar. The result is that when we run Ant and try to undeploy the application all files but the struts.jar are removed and the deployment process fails. Although Tomcat has access to all the jars in the various libs (common, shared and server) it only has access to the struts jars in the application libs. We use Process Explorer to verify this. There seem to be several threads reporting similar behavior. Our present solution is to operate with unpacked wars (it works) but we would like to improve the performance with unpacked wars.

Re: banned
Good point, assuming that what Mark says is true, that he was fired, this is all bad. I recognize your need to ban people and if it helps improve the signal to noise ratio on this list, I'm all for it. I also recognize that we are all responsible for what we say here. Both the first time around through email and the second time around in the archives. But in this instance, Mark doesn't have only himself to blame. Someone sent his comments to his workplace and resulted in him being fired. I've worked will some major jerks over the years who wrote great code, slung great servers, etc etc. Just because someone's has unpopular views or is terribly annoying or extremely frustrating or whatever does not justify maliciously alerting their employers. This just leaves a bad taste in my mouth. All you need to do is to create a filter and individuals can ban anyone they want. The email to MD dept of elections is spiteful and childish and way more damaging to the struts community than any bigoted and/or stupid posts.

Is it possible to assign Form Beans to a form instead of assigning them to an action? Thanks, ~ Andrew Tomaka If you do not have prejudice against form bean with session scope, you can use Struts Dialogs and create two JSP Controls. Each JSP Control contains an action class and a form bean. For action class you either can directly use DialogAction, or you may have to subclass it. Include both controls (that is, their actions) into your JSP using jsp:include. The submit request is sent directly to each control. You need to set up action mapping for each control to set the target/reload location. For the first control this would be you JSP page, in which you embed the controls. Struts Dialogs home page: http://struts.sourceforge.net/strutsdialogs JSP control how-to: http://struts.sourceforge.net/strutsdialogs/dialogaction-logincontrolsample.html Live demo of JSP control: http://www.superinterface.com/strutsdialog/embeddedmasterpage-tomcat.do In the live demo the Sign In box is a JSP control. The catch: if you use Tomcat, you cannot forward from action to JSP to render a control, Tomcat closes response writer right after forward. So you would need to design forward to JSP in regular way, then run your app, Jasper will generate Java source code for your JSP, then you need to copy that source code to your project. See the samples, they contain all needed code. This issue will be addressed in next SRV spec. It is a little hassle, but result worth it ;) Michael. -- Dialogs for Struts http://struts.sourceforge.net/strutsdialogs - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: prepopulating the form again
Tony Dahbura wrote the following on 7/6/2005 11:09 PM:
So I have a setup action. How do I in this setup action setup my
ActionForm values so when I forward control to the form they are there
and present for display. This form is being used to allow updating data
and I want to prepopulate the fields for the user.
My form is an editUserForm that has an editUser action as well. Should
I in my editUser action call the setters of the editUserForm and set the
values? Then just call the jsp page that will reference these through
the editUserForm? I agree using reset is not proper given the
documentation-just not sure how I should do this...
The editUserForm is in request scope as well not in session scope
Ok Tony, before Michael replies with the use of another framework
(joking sort of:), this is very easy to do with Struts and as a side
note, I really don't see why people have to constantly make Struts more
confusing than it needs to me. You can accomplish 99% of what you want
with this simple design (and then I'll address your issue directly).
For the sake of this discussion I'm going to assume you are using a
DispatchAction. In case you don't know, a DispatchAction just lets you
combine similar types of behaviors into one Controller... so rather than
have an UpdateUserAction, DeleteUserAction, etc.. you have one Action...
UserAction with methods in it update(..), delete(...), etc.
So typically here's what I do and it covers 'almost' all of my
scenarios. I find it easier to work with examples and your User is a
good example to work with. Lets say we want to CRUD (create, retrieve,
update, delete) for a User.
1) Step 1 Create a UserActionForm
For simplicity it has just two main properties...
String userName;
Integer userID;
Also though we are going to provide the dispatch (or action) as
a property to give it default value of add
String dispatch = add
This way if we go right to the page it'll have 'add' by default
2) Step 2 Have a BusinessObject back reprsenting your User. I like to
pass Business objects (not tied to Struts to my backend), so you'll have
in this case a simple:
UserVO (value object.. could just call it User but for this
discussion seeing VO helps you understand what it is)
String userName;
Integer userID;
//NOTE: it helps if the properties of the VO and the ActionForm have
the same name. Not a requirement but makes things easier which I'll show
3) Create a UserDispatchAction
This will have the following methods:
(all with signature public ActionForward methodName (ActionMapping
mapping, ActionForm form, HttpServletRequest request,
HttpServletResponse response)
setUpForEdit(..)
setUpForAdd(..)
add(...)
edit(...)
delete(...)
getUsers(...)
Before I get to the setUpForEdit() lets just handle the others...
In all cases you will be submitting either a form or a link but in
the struts-config file this will map to our UserAction where we also
include the name of our UserActionForm, so our UserActionForm is always
populated.
So our Add method in our Action...
//**ADD
public ActionForward add(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws Exception {
UserActionForm userForm = (UserActionForm)form;
UserVO user = new UserVO():
//copy our form properties into the VO
PropertyUtils.copyProperties( user, userForm );
ourBackendDelegate.addUser( user );
return mapping.findForward(to_form);
}
// UPDATE and DELETE...
Same as above except for use of...
ourBackendDelegate.deleteUser( user );
ourBackendDelegate.updateUser( user );
// THE SET UP FOR EDIT
Ok, this is the one you were asking about. Now you have to think about
how you would get here? Typically you'd get to an edit page by clicking
on a user record to say Hey, I want to edit this guy's user
information So imagine a case where we have a list of users and
'userID for each in the list, they click on the link and they'll come
to this method which will get our user and then forward them to a page
to do the editing. The method will look like...
public ActionForward setUpForEdit(ActionMapping mapping, ActionForm
form, HttpServletRequest request, HttpServletResponse response) throws
Exception {
UserActionForm userForm = (UserActionForm)form;
//userID is set in this form when the user clicked on the link
//lets get our real business object of this user, based on ID..
UserVO user = ourBackendDelegate.addUser( userForm.getUserID() );
//copy the other way this time, from UserVO to our Form...
PropertyUtils.copyProperties( userForm, user );
//finally we are going to reuse or form for add and edit, so
//we will set up our dispatch/action parameter
userForm.setDispatch(edit);
return mapping.findForward(to_form);
}
//The get users - this will display our users on the page
public ActionForward getUsers(ActionMapping mapping,

String userName;
Integer userID;
Also though we are going to provide the dispatch (or action) as
a property to give it default value of add
String dispatch = add
This way if we go right to the page it'll have 'add' by default
2) Step 2 Have a BusinessObject back reprsenting your User. I like to
pass Business objects (not tied to Struts to my backend), so you'll have
in this case a simple:
UserVO (value object.. could just call it User but for this
discussion seeing VO helps you understand what it is)
String userName;
Integer userID;
//NOTE: it helps if the properties of the VO and the ActionForm have
the same name. Not a requirement but makes things easier which I'll show
3) Create a UserDispatchAction
This will have the following methods:
(all with signature public ActionForward methodName (ActionMapping
mapping, ActionForm form, HttpServletRequest request,
HttpServletResponse response)
setUpForEdit(..)
setUpForAdd(..)
add(...)
edit(...)
delete(...)
getUsers(...)
Before I get to the setUpForEdit() lets just handle the others...
In all cases you will be submitting either a form or a link but in
the struts-config file this will map to our UserAction where we also
include the name of our UserActionForm, so our UserActionForm is always
populated.
So our Add method in our Action...
//**ADD
public ActionForward add(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws Exception {
UserActionForm userForm = (UserActionForm)form;
UserVO user = new UserVO():
//copy our form properties into the VO
PropertyUtils.copyProperties( user, userForm );
ourBackendDelegate.addUser( user );
return mapping.findForward(to_form);
}
// UPDATE and DELETE...
Same as above except for use of...
ourBackendDelegate.deleteUser( user );
ourBackendDelegate.updateUser( user );
// THE SET UP FOR EDIT
Ok, this is the one you were asking about. Now you have to think about
how you would get here? Typically you'd get to an edit page by clicking
on a user record to say Hey, I want to edit this guy's user
information So imagine a case where we have a list of users and
'userID for each in the list, they click on the link and they'll come
to this method which will get our user and then forward them to a page
to do the editing. The method will look like...
public ActionForward setUpForEdit(ActionMapping mapping, ActionForm
form, HttpServletRequest request, HttpServletResponse response) throws
Exception {
UserActionForm userForm = (UserActionForm)form;
//userID is set in this form when the user clicked on the link
//lets get our real business object of this user, based on ID..
UserVO user = ourBackendDelegate.addUser( userForm.getUserID() );
//copy the other way this time, from UserVO to our Form...
PropertyUtils.copyProperties( userForm, user );
//finally we are going to reuse or form for add and edit, so
//we will set up our dispatch/action parameter
userForm.setDispatch(edit);
return mapping.findForward(to_form);
}
//The get users - this will display our users on the page
public ActionForward getUsers(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws Exception {
//lets say pass in companyID
Integer companyID = Integer.valueOf( request.getParameter(companyID));
//get our list of users to display on page
List users = ourBackendDelegate.getUsers( companyID );
request.setAttribute(users, users );
return mapping.findForward(to_display);
}
4) sample config...
action path=/userMaintenance type=com.foobar.UserAction
name=userActionForm
scope=request
validate=false
parameter=dispatch
forward name=to_form path=/userForm.jsp/
forward name=to_display path=/displayUsers.jsp/
/action
5) Sample form
html:form action=/userMaintenance
Name: html:text property=name/br/
html:hidden property=userID/
html:hidden property=dispatch/
Re: Two Forms, Two Form Beans, One JSP
I imagine I've over complicated the problem, so I've taken a step back and am looking at it from the beginning again. The following are my basic requirements: When the user makes the first request, they are taken to a page with a drop down menu. This drop down menu is built from information stored in a database so I need to do some pre-processing. After that, the user chooses an option from the drop down menu and chooses to search. This returns a page that has the same form that was built in the first request on top and then a second form that lists the results of their drop down. This allows users to choose which of the results to edit. At this point the user can either use the drop down menu and have the bottom list rebuilt or choose a result to edit and proceed. My problem is that I have a PreAction to do the processing on the form. This requires the page to have the form bean assigned to it. Since I have two different forms doing two different things, I should have two different form beans, but I don't see how I can accomplish that. This is going to be a common thing to do throughout my entire application so I am hoping a simple design solution will pop up. Let me know if you need any other clarifications.

I had a similar situation and I used only one form, with the bottom part(result) inside a div, which is only visible depending on the action you took on the top part(search param part), otherwise it's invisible.

Re: Refresher for newbies (part 2)
After reading the initial newbie post, you then might come across a situation where you need to have some things like lists on the page that aren't related to your ActionForm. For example, in the User example just given, imagine you need the person using the form to select a Department that the user belongs in. You thus need a way to make sure that a List of department is available on the page for the user to select from. Now before we get a ton of responses about how here's why I came up with this for Struts, and here's my solution..., I understand that many of the ideas that many of you have come up with our very ingenious and very practical once you understand the framework. I believe, however, for someone new to Struts that it's better to Keep Things Simple and keep things fairly consistent with what they are used to. For this reason I suggest you do things this way In your DispatchAction simply provide a prep( HtttpServletRequest request) method. In there you simply do any preparation of things your form might need. *NOTE* *NOTE* NOTE*: This is NOT, NOT, NOT where you do things like populate the form with user information etc. This is only where you would do things like provide lists for drop down so they are in scope. The next more advanced question is well what happens if you are using validation and validation fails, how are these going to be in scope? I believe the answer is quite simple... just call validate from your Action class versus relying on Struts to call it based on your struts config setting! I have more on this here http://www.reumann.net/struts/articles/request_lists.jsp The benefit to the prep() and the calling validate manually is everything is quite simple... you are using a standard DispatchAction which is easy for people to understand PLUS everything is all in one place. When dealing with editing Users you can look in your UserDispatchAction and see what's going on. No need to look at a bunch of xml config settings, AspectJ inserts, or some other hidden stuff. Granted yes, the newer frameworks handle all of this more gracefully, but the problem is not that big of a deal with Struts. I've written some pretty complex applications and the above has been working fine and it becomes so simple to do. -- Rick - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Refresher for newbies...
Any reason in getUsers() that you are going directly to request to get the
companyID parameter, as opposed to getting it from the form?
It might be worth noting that some people dislike the use of
DispatchAction in most cases, me included. This is a fairly minor point
as the actual code you wrote would be essentially unchanged without
DispathAction, just housed in individual classes. I'm not sure one answer
is really better than the other, it's been debated at various points, but
as long as people understand there's nothing that says you have to do this
in a DispatchAction, then it's all good :)
(For any newbies reading this, the difference that matters is that with a
DispatchAction, you have a single entry in struts-config, but you have to
pass a parameter with each request. With plain Actions, you would have
multiple mappings like /setupForAdd, /setupForEdit, /add, /delete and so
on in this case, but no parameter to pass around. There are pluses and
minuses to each approach, but they get you to the same basic place in the
end.)

Re: [OT] Using connection pools - security
You could also just use one pool per user role and look up the db user and the role that user is in, then pull the connection from the pool that you have for that role. If your DB doesn't support roles for users you could create a user/role table. I think it might be overkill to create an actual user in your database for each user in your application. If that is your requirement though then that is your requirement. Michael On 7/6/05, Craig McClanahan [EMAIL PROTECTED] wrote: A couple of considerations are relevant here: * Is a single user ever going to really use more than one connection from the pool? If not, wouldn't it be better to create a *connection* for them, instead of a *pool*? (Note in particular that transactions don't cross connection boundaries, so if you want all or nothing commits, you need to do them on a single connection anyway). * Creating even one connection per user is going to require more active connections to your database than sharing the same pool for all users. In the cases where you are using the DB to restrict access to things (by username), one approach would be to use something like Oracle's database roles instead. That way, the code that retrieves a generic connection from an application wide pool could also do a SET ROLE (or whatever the appropriate command is -- it's been a few years since I was this deep into databases) that established the restrictions for the currently logged on user. That way, you could continue to share a single pool across all your users, and minimize the number of connections your DB has to support to just the number of currently active requests. Of course, the latter solution depends on your database having the capability to do this -- I know Oracle does, but don't know about others.

Maybe it would be nice however to return the first connection quickly and then create the others in a background thread. Since there could be a lot of users I should have a max-connection-pools config-param. When is reached I will remove the connection pools of user's who haven't used the object recently.

Re: Two Forms, Two Form Beans, One JSP
I did consider using a single form bean for both forms, but it didn't really sit well with me from a design stand point. We have two different forms doing two different things so there should be two different beans. Heck, if I had it my way, the two forms would be on separate pages (wizard style), but the customer says otherwise. I do have an issue with using a single form. The top list is a list of program ids. When a program id is selected, it brings up all the different sheets for that program id. The user can then select a sheet to edit, via radio button, and submit that request. With this request, I need to pass the program id that was selected (via hidden field). I can't rely on the program id in the drop down box because if a user performs a search, changes the drop down box and then selects a sheet to edit, we have a mismatch between the intended program id to edit and the actual program id to edit (if that makes any sense). ~ Andrew Tomaka On 7/7/05, Wendy Smoak [EMAIL PROTECTED] wrote: From: Andrew Tomaka [EMAIL PROTECTED] My problem is that I have a PreAction to do the processing on the form.

Re: Refresher for newbies...
Thanks Rick,
I'd like to clarify something here.
UserActionForm userForm = (UserActionForm)form;
//userID is set in this form when the user
clicked on the link
So, even though the jsp containing the list of users
and the links to edit each of them doesnot contain a
form tag, your userForm will still be created and
assigned a userID? I guess that is the case due to the
fact that the UserForm is defined for the
DispatchUserAction and has a request scope so the form
will always be created when the action is invoked.

Re: Two Forms, Two Form Beans, One JSP
Does the ActionForm for the bottom form only come into play when a selection is made in the upper form? If so, you could always instantiate the ActionForm yourself, populate it as appropriate in the Action that fires when that selection is made, shove it in request and deal with it manually. One exceedingly hacky way to do this, and I'm not sure it would work but it would be a neat experiment, is something like this: In the Action: -- MyLowerActionForm m = new MyLowerActionForm(); // Populate ActionForm as appropriate request.setAttribute(m, m); (of course you wouldn't use m as the key, but you get the idea!) Then in your JSP, have the upper form that is exactly like it probably is now, then, right before the lower form, add this line: % request.setAttribute(, request.getAttribute(m)); % is the key that the ActionForm would be found under if the lower form was the only one involved. Then code your form as usual. What I'm thinking is that you'd want to use the same usual tags for both forms, and allow Struts to do its thing as far as populating and such goes... this obviously won't work if the upper form requires a different ActionForm than the bottom, but if you overwrite the ActionForm that would be in request at that point for the upper form with the one you manually added to request for the bottom form, that might work. *IF* that does work, I'm not at all sure it's a good idea, but it's an intersting thought. -- Frank W.

Andrew, if the data being edited in the two forms are related, then for the child data you could use a nested bean as an attribute on the form.

Frank W. Zammetti wrote the following on 7/7/2005 12:43 PM: Any reason in getUsers() that you are going directly to request to get the companyID parameter, as opposed to getting it from the form? For a full blown app, I'd probably have a CompanyActionForm which would hold companyID and I'd use that to be consistant. But you aren't required to use an ActionForm for 'everything.' For a single ID nothing 'that' bad about pulling it straight from the Request. It might be worth noting that some people dislike the use of DispatchAction in most cases, me included. This is a fairly minor point as the actual code you wrote would be essentially unchanged without DispathAction, just housed in individual classes. Agreed. I think I mentioned you could use invidual Actions just as easily, if I didn't I apologize. (If using separate related Actions I still 'might' inherit from a BaseUserAction though to keep certain things like a prep() method in the Base, but that's not a firm requirement). (For any newbies reading this, the difference that matters is that with a DispatchAction, you have a single entry in struts-config, but you have to pass a parameter with each request. With plain Actions, you would have multiple mappings like /setupForAdd, /setupForEdit, /add, /delete and so on in this case, but no parameter to pass around. There are pluses and minuses to each approach, but they get you to the same basic place in the end.) Yup. Both have plusses and minuses. Since so little really goes on in the methods of the dispatch action, I just tend to prefer it but I also the valid claim that separate Actions are good and 'maybe' more OO as well (although that could be debated). -- Rick - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

klute wrote the following on 7/7/2005 12:56 PM: UserActionForm userForm = (UserActionForm)form; //userID is set in this form when the user clicked on the link So, even though the jsp containing the list of users and the links to edit each of them doesnot contain a form tag, your userForm will still be created and assigned a userID? I guess that is the case due to the fact that the UserForm is defined for the DispatchUserAction and has a request scope so the form will always be created when the action is invoked. More specifically it's due to the fact that the URL path for the link is defined in the struts-config action mapping, so yes the ActionForm will be instantiated by Struts. This is a good point to bring up because many think you 'have' to use a html form in order to get an ActionForm populated, but as you have noticed, this is NOT the case. A URL will work just as well.

Re: Two Forms, Two Form Beans, One JSP
Using a nested form bean may actually be a viable solution that I'll have to look in to. Ideally though, I'd be able to treat the two different forms as two separate pages that just happen to share the same screen space.

I posted this in reply to Tony's post, but figured this stuff comes up
all the time and to those new to Struts, this below might help
You can accomplish 99% of what you want with this simple design
Ok, Rick, lets pull out and compare :-) But before I go into
presenting my approach, could you tell me, what happens in your app
when a user clicks Refresh? Or Back?
For the sake of this discussion I'm going to assume you are using a
DispatchAction. In case you don't know, a DispatchAction just lets you
combine similar types of behaviors into one Controller... so rather than
have an UpdateUserAction, DeleteUserAction, etc.. you have one Action...
UserAction with methods in it update(..), delete(...), etc.
I will use my DialogAction, which subclasses DispatchAction, adding an
important feature to it: two-phase request processing aka
Redirect-after-Post. It helps to avoid resubmits, and makes the whole
process of input/change state/render view much easier.
So typically here's what I do and it covers 'almost' all of my
scenarios. I find it easier to work with examples and your User is a
good example to work with. Lets say we want to CRUD (create, retrieve,
update, delete) for a User.
1) Step 1 Create a UserActionForm
For simplicity it has just two main properties...
String userName;
Integer userID;
Fine with me. I use abstract items with ID, strvalue and numvalue.
Also though we are going to provide the dispatch (or action) as
a property to give it default value of add
String dispatch = add
This way if we go right to the page it'll have 'add' by default
My DialogAction or its subclass CRUDAction (thanks for this great
example, I have action exactly for this use case) does not have any
default values. If you navigate to the action, it simply shows current
data for current state. So, as you see, my actionform has session
scope to be stateful.
2) Step 2 Have a BusinessObject back reprsenting your User. I like to
pass Business objects (not tied to Struts to my backend), so you'll have
in this case a simple:
UserVO (value object.. could just call it User but for this
discussion seeing VO helps you understand what it is)
String userName;
Integer userID;
//NOTE: it helps if the properties of the VO and the ActionForm have
the same name. Not a requirement but makes things easier which I'll show
I don't care much about how VO/BO is mapped to actionform. Basically,
if you want values to be populated from request, and to be used in
JSP, either create setter/getters in the actionform, or set VO/BO as
nested property of the actionform.
3) Create a UserDispatchAction
This will have the following methods:
(all with signature public ActionForward methodName (ActionMapping
mapping, ActionForm form, HttpServletRequest request,
HttpServletResponse response)
setUpForEdit(..)
setUpForAdd(..)
add(...)
edit(...)
delete(...)
getUsers(...)
I have generic CRUDAction, which has create(), duplicate(), edit(),
view() and delete() methods. And of course, getView(), which renders a
proper page.
Before I get to the setUpForEdit() lets just handle the others...
In all cases you will be submitting either a form or a link
DispatchAction and its subclasses accepts input as form submission
only (POST), because it detects input phase or render phase by request
type. I think, this is a reasonable limitation.
but in
the struts-config file this will map to our UserAction where we also
include the name of our UserActionForm, so our UserActionForm is always
populated.
So our Add method in our Action...
//**ADD
public ActionForward add(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws Exception {
UserActionForm userForm = (UserActionForm)form;
UserVO user = new UserVO():
//copy our form properties into the VO
PropertyUtils.copyProperties( user, userForm );
ourBackendDelegate.addUser( user );
return mapping.findForward(to_form);
}
The corresponding create() method in CRUDAction from Struts Dialogs
looks like this:
public ActionForward onCreate (ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
// Action Form must implement ICRUDForm
ICRUDForm crudForm = (ICRUDForm) form;
// Create new business object (item), and get back errors if any
ActionMessages messages = crudForm.crudCreate();
// Successfully created new object and initialized action form
if ((messages == null) || messages.isEmpty()) {
// Need to handle this forward object in struts-config.xml
return

public String getFirst_name() {
return first_name;
}
public void setFirst_name(String first_name) {
this.first_name = first_name;
}
}
In my JSP, I have the following:
html:form action=/processRequestAccess method=POST
table border=1

tdhtml:text property=institution_name //td
tdbean:message key=title //td

tdbean:message key=address1 //td
td/td
tdbean:message key=first-name //td
tdhtml:text property=dnaForm.first_name //td !-- DOESN'T LIKE THIS

/tr
.
/html:form

Re: Two Forms, Two Form Beans, One JSP
You can have multiple forms on the same page. I am using Tiles. I put some forms in the header/footer and they work just fine. I had to use different actions for the two forms, and I had to use session scope for one of them in order to retain state for it.

Re: Refresher for newbies...
Typo: I wrote DispatchAction and its subclasses accepts input as form
submission
only (POST). Must read as DialogAction and its subclasses accepts
input as form submission only (POST)
Also, two other methods for completeness. This one is called when a
user submits new/updated item to persist it. This is input phase.
public ActionForward onSave (ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
HttpSession session = request.getSession();
ICRUDForm crudForm = (ICRUDForm) form;
// Validate input data
ActionMessages messages = form.validate(mapping, request);
// Input data is not valid
if (messages != null messages.size() 0) {
session.setAttribute(Globals.ERROR_KEY, messages);
return mapping.findForward(CRUDConstants.MAPPING_ON_INVALID_DATA);
// Input data is valid
} else {
// Try to persist form data
ActionMessages storeMessages = crudForm.crudStore();
// Could not persist form data
if (storeMessages != null storeMessages.size() 0) {
session.setAttribute(Globals.ERROR_KEY, storeMessages);
return
mapping.findForward(CRUDConstants.MAPPING_ON_STORE_FAILURE);
// Successfully persisted
} else {
return
mapping.findForward(CRUDConstants.MAPPING_ON_STORE_SUCCESS);
}
}
}
Another forwards to a proper page, this is render phase. This
particular implementation uses CRUD mode for page mapping.
public ActionForward getDialogView(ActionMapping mapping,

HttpServletRequest request,
HttpServletResponse response)
throws Exception {
ICRUDForm crudForm = (ICRUDForm) form;
String uiMode = crudForm.getCrudUIMode();
return mapping.findForward(uiMode);

Re: Getter/Setter
If you mean writing a single method that handles multiple elements, then the way to handle this is with DynaBeans. Struts uses BeanUtils to populate the forms, and the DynaBean interface provides support for a set of generic set/get methods that can handle normal, indexed, and mapped properties. Thus, you can build a bean backed by a map, a result set, etc. To make this work for a form see DynaForm and override some of the get/set methods, or use it as an example and make your own variant.

on a user record to say Hey, I want to edit this guy's user
information So imagine a case where we have a list of users and
'userID for each in the list, they click on the link and they'll come
to this method which will get our user and then forward them to a page
to do the editing. The method will look like...
public ActionForward setUpForEdit(ActionMapping mapping, ActionForm

//userID is set in this form when the user clicked on the link

Re: Refresher for newbies...
This is exactly what I mean. If you recall the definition, Location != URL. Instead, Location == URL + request params. Most browsers build up page history using locations, of the browsers known to me, only Opera uses actual responses. That means, that if you load the same page five times in Opera, it will put five entries into page history. But most other browsers do not do that, they put only one entry in page history, because all pages has the same location. Another trick is using redirection. Browsers forget location, which preceds redirected request. If you redirect from each POST to result page, result page is loaded with GET, this is how browsers work. Say, you submit the same form three times, you have the following request sequence: POST-GET-POST-GET-POST-GET, right? Three pairs of POST-GET What goes to the page history? The answer is, that requests preceding redirected request do not go, so it would be GET-GET-GET. This is what sucky Opera is doing. They explain this by 13.13 chapter of HTTP1.1 spec. Whatever. Other browsers do not do that, and also consider themselves compliant to HTTP spec. So, other browsers see that all GET in the GET-GET-GET point to the same location (see definition above). So, they just throw all of them but one, because they consider it the same resource. Now you get your page history: -GET- That is all! Now, combine that with non-cachable pages, and you can serve different content from the same locaiton, which is stored in the same history slot.

dialog stuff (was) Re: Refresher for newbies...
(moved to new topic heading, but keeping seem referenceID for those
threading)..
Michael Jouravlev wrote the following on 7/7/2005 1:40 PM:
Ok, Rick, lets pull out and compare :-) But before I go into
presenting my approach, could you tell me, what happens in your app
when a user clicks Refresh? Or Back?
Sure. No problem. It depends on the application. If it's a requirement
that data does not get submitted twice I simply use the token approach
that is very easy to implement. It doesn't take much at all to ensure
duplicate entries do not get entered. If the user hits 'back' on their
browser button most of the time that page info displayed is cached by
the browser. If it's critical that the page always show fresh data
(which usually it is not) then ther are ways to ensure that also (doing
the pragma, no-cache stuff like you do in your DialogAction).
I will use my DialogAction, which subclasses DispatchAction, adding an
important feature to it: two-phase request processing aka
Redirect-after-Post. It helps to avoid resubmits, and makes the whole
process of input/change state/render view much easier.
Like I said if resubmits are in issue just use the Token approach. It's
super easy and documented.
My DialogAction or its subclass CRUDAction (thanks for this great
example, I have action exactly for this use case) does not have any
default values. If you navigate to the action, it simply shows current
data for current state. So, as you see, my actionform has session
scope to be stateful.
My DispatchAction doesn't have default values either. I'm not sure what
you are talking about here. If I want to keep state, I simply give my
ActionForm session scope and or if I want list of users to have state I
put it in session scope. What's new about giving an ActionForm session
scope?
I don't care much about how VO/BO is mapped to actionform. Basically,
if you want values to be populated from request, and to be used in
JSP, either create setter/getters in the actionform, or set VO/BO as
nested property of the actionform.
Agreed. I often do the same (nest a VO/BO in my ActionForm, although
this wouldn't be the initial approach I'd give someone just starting out).
I have generic CRUDAction, which has create(), duplicate(), edit(),
view() and delete() methods. And of course, getView(), which renders a
proper page.
Yes I see that.
DispatchAction and its subclasses accepts input as form submission
only (POST), because it detects input phase or render phase by request
type. I think, this is a reasonable limitation.
Not true. I pass stuff with a get all the time using a URL.
The corresponding create() method in CRUDAction from Struts Dialogs
looks like this:
public ActionForward onCreate (ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
// Action Form must implement ICRUDForm
ICRUDForm crudForm = (ICRUDForm) form;
// Create new business object (item), and get back errors if any
ActionMessages messages = crudForm.crudCreate();
// Successfully created new object and initialized action form
if ((messages == null) || messages.isEmpty()) {
// Need to handle this forward object in struts-config.xml
return mapping.findForward(CRUDConstants.MAPPING_ON_CREATE_SUCCESS);
// On error save messages into session. Struts 1.2.6+ has
// a special method for it; this code saves errors directly
// to session for compatibility with older Struts versions.
} else {
HttpSession session = request.getSession();
session.setAttribute(Globals.ERROR_KEY, messages);
// Handle this forward object in struts-config.xml
return mapping.findForward(CRUDConstants.MAPPING_ON_CREATE_FAILURE);
}
}
Yes, I saw this in the code I download. I see what you are doing -
basically have a generic Action that tells the form to update, delete,
etc. Again, I think this is pretty 'cool' but I don't think it is that
much of a time saver and it is definitely a totally different paradigm
from all the Struts stuff out there. Not saying it's not a good concept,
I'm just stating that is more difficult to grasp at first since it's not
how Struts was desgined. You are free to mold it however you want and
that's the beauty of open source, but I don't see your solution as that
much more of a time saver or any easier to understand than the basic
approaches.
ALSO I will amost GUARANTEE you that in reality you will almost always
end up having to do other things when an update/edit/delete takes
place... maybe you'l have requirements that you need to stuff something
else into the request, maybe something else into the session - you'll
say do this all in your the CRUDForm

execute instead of get and post
Is there a good reason why Struts does not distinguish between GET and POST requests and tunnels both through execute()? It seems like it would make sense to have both so that you can use GET to set up a particular form and POST to process that form. Instead, I'd have to look at the request to see what was invoked and then conditionally do some processing. James Sell on Yahoo! Auctions no fees.

Re: Shale Users
Things in Shale are going pretty well -- with David's checkin of the integration with standalone Tiles (from the Struts sandbox), Shale is now pretty much feature complete with respect to Struts 1.x, while offering some ease of development benefits due to JSF and it's own features. The only functional areas I still want to flesh out some more before a milestone release are: * Making it possible to have multiple dialogs active at the same time (for a dialog in each Tile, for popups, etc) * On the remoting support, make the JSF lifecycle available so you can use things like value binding and method binding expressions while creating the response. I don't anticipate that either of these changes will cause any fundamental breakage in the APIs, so it's definitely worth some experimentation time.

RE: Two Forms, Two Form Beans, One JSP

Or Back? Sure. No problem. It depends on the application. If it's a requirement that data does not get submitted twice I simply use the token approach that is very easy to implement. It doesn't take much at all to ensure duplicate entries do not get entered. Yes, it does not take much. But it is not the best solution. Token works *after* POST request has been resubmitted. It can help to prevent *data resubmission* on business/persisntence layer, but it does nothing to prevent browser message: Do you want to resend POSTDATA? What? What is POSTDATA? I don't care what it is, and I don't know do I want to resend it or not, just show the damn page. The simple send POST, get page approach results in horrible UI, like I had to go through when I was ordering parts for my car. Car make-POST form. Model-POST form. Year-POST form. Suspension part-POST form. Struts (no put intended)-POST form - (looking for Tokico struts, don't see any). Go Back. Do you want to resend POSTDATA? - No - I see the same page. Back again. Do you want to resend POSTDATA? - Yes - The previous page is reloaded with the same POST, running the same query on the server. Same happens three or four more times. I wanted to strangle the programmer who desinged that. Right, if pages were cachable, it would help. Or if I used Opera. But this is only one example of many. In other cases Opera does not help, it gets in the way. Another example. You want to log in. You enter name, it is incorrect, it is redisplayed. Again, and again, and again. You decided to drop the idea, and to return back. How many times you need to click Back? Also, token does knows nothing about your business data. You are shopping in the online store. You selected item, clicked Add to cart, it was added, and you forwarded to another page. Then you realised that you need two of them. You click Back, see the same item again and click Add to cart. Now it tells you that you cannot do this, because you are resubmitting the same request, apparently by mistake. Your webapp can prove it to you, it has the token. But it is not a mistake, you actually want to add the same item again. So, tokens better than nothing, like Yugo comparing to bike. But it is still a Yugo.

What I have a problem with is ... 1) The inconsistency in what is protected. For example everyone today talks about tolerance. But what does this mean? What it ends up meaning is There are no moral absolutes so the only valid belief system protected is one that doesn't espouse moral judgments. But what about being tolerant to the idea that someone might feel otherwise? Why is state sanctioned secularism the only valid religion (and yes secularism is a belief system - a religion). It's sort of funny that those whom often claim to be the most 'tolerant' are often the most vicious when it comes to attacking someone that disagrees with their view of tolerance. There are many views I could state that would get me labeled as being 'intolerant,' yet, somehow it's supposedly not offensive to state All views on X,Y,orZ are equally acceptable. To me, and many others, that later position can be considered extremely offensive. Why is only one view (secular humanism) considered 'non offensive' but other religious views are some how bigoted and intolerant. It's pure hypocrisy. In Germany, in a major part thanks to the US (I mean it!), religious freedom, for instance, is granted to everyone in our Constitutional Law (Art. 4 GG). Getting fired just because of one's religious views is impossible by law. So I, who believes in Jesus Christ as my personal saviour and follows the Bible as his above-all-worldly-wisdom guide can happily work together with Hindus and common atheists, in- cluding my boss. I can even tell them if they're on the road to eternal doom, the same as they may tell me I'm ridiciously wrong, and still keep my job. And in fact, the Bible is quite intolerant when confronted with modern secularism, but what's my choice? As for general opinions and secular beliefs, we have Art. 5 GG which grants freedom of speech. So there's no need for hypocrisy here at all. On the other hand, I definitely never would use a company e-mail address for anything other

What do you mean when you say it doesn't work?
I compared your code with something I have that's working and they

nested:text property=ssNumber size=9 maxlength=9/
nested:text property=salary size=12/

field property=birth indexedListProperty=employees
depends=required,date
arg0 key=employeeform.birth.displayname/
var
var-namedatePatternStrict/var-name
var-valueMM/dd//var-value
/var

field property=ssNumber indexedListProperty=employees
depends=required,integer
arg0 key=employeeform.ssnumber.displayname/
/field
field property=salary indexedListProperty=employees
depends=required,mask
arg0 key=employeeform.salary.displayname/
var
var-namemask/var-name
var-value^\$?\d+(,\d{3})*(\.\d{2})?$/var-value
/var
/field
This app is using Struts 1.2, though. If you want to try it out, it's
available at http://www.rabago.net/struts/formdef/dev/nested.war .
It's using FormDef (which is a Struts plugin) but FormDef doesn't
affect validation, so the same rules apply. Using nested tags also
don't affect validation. In fact, you could use plain old HTML tags
and still use Validator, as long as you name your fields correctly
and/or populate your form beans properly.

This does not work, although as far as I can tell, this is how the

However, in the jsp, the values are collected using the nested tag,
not the logic/bean tags.
nested:iterate property=jobs

Would this interfere with the validation, or are the two tags
identical when it comes to validation?

You said it would be an enterprise j2ee application, right? So there is a chance it would be distributed once? In this case using ActionForms as VO is an absolute NO GO ! Besides, if you want a clear architectural separation of layers its a NO GO also! The VO Objects are parts of your business logic interface (I hope you have one) and ActionForm have nothing to do with business logic or, even worse, DAOs. A typical enterprise architecture is 3 layered: Presentation with Actions / ActionForms / jsps Business with business interfaces and VOs or DTOs (name it as you like it) Persistence with DAOs And, from practical experience, your Forms may seem to be mirrors of the database at the beginning, but this will change as soon as your application start to live (Think about collections for drop-downs for example).

The VO Objects are parts of your business logic interface (I hope you have one) and ActionForm have nothing to do with business logic or, even worse, DAOs. A typical enterprise architecture is 3 layered: Presentation with Actions / ActionForms / jsps Business with business interfaces and VOs or DTOs (name it as you like it) Persistence with DAOs And, from practical experience, your Forms may seem to be mirrors of the database at the beginning, but this will change as soon as your application start to live (Think about collections for drop-downs for example).

Re: Using struts forms as Value Objects: your opinion?
An alternative would be to have your form class extend your value object class. However, this approach doesn't work for me. My form class fields are always Strings (because of HTTP), while my value object fields are whatever types make sense (such as Date). I always have value object classes that look very similar to my forms, but the types vary. It doesn't bother me. Check out Jakarta BeanUtils for auto-conversion of field data between form class and value object class.

Re: Using struts forms as Value Objects: your opinion?
Also you could economize your development by using Struts Dyna-flavored forms (generated from xml) instead of writing your own form classes. Instead, I use a class I wrote that scans a properties file which has a comma-separated list of fields and their types, and some other data such as desired class name, default access modifier, etc. The class produces source files with typed fields (or an all-String version if I'm making a form class) and all the getters and setters. Saves all that unnecessary typing. All I do is write a properties file for each form and/or value object class I want. You can go a step further and create value object classes based on database metadata . . .

Re: Using struts forms as Value Objects: your opinion?
I usually build my ActionForm classes with the VO on it as a property. The String properties can be just refered to as bean.property on the jsp. Any non-string properties I map to the bean in the action form, with the translation - so if there is a date, for instance, the property on the action form might be someDate, and in it's setter, i store the string, parse it using a dateformat object, and store it into the bean if it is a valid format. If the format is bad, i keep the string for display back to the user. That way, by the time the action gets the form the bean has all the properties and the types are correct.

Fw: Re: Using struts forms as Value Objects: your opinion?
Sorry, Michael, I accidentally sent this directly to you . . . I'm not sure why you say save a call to the backend unless by backend you mean anything outside of the web tier. In my applications, it would typically save a call to the manager layer, which I consider the middle, not the backend. It would not typically save a call to the persistence layer -- the backend -- as managers usually don't need to access a persistent store to perform manager-layer validation (I suppose there are exceptions). So, different layer, as you say, but same VM usually. For a much-distributed application, I could see the argument about saving the call to any other layer, but, I would need another solution for that problem, such as a local manager. I don't typically have any classes that resemble what you are describing as a business object. I typically have managers, value objects, helper objects (mini-managers if you will), and data access objects. Value objects are the only ones that cross tier boundaries, and they are completely dumb. This creates weak coupling, which I prefer. I don't recall having any business object classes that had the same fields as value objects plus business logic. I suppose back when I was writing entity beans there might have been some. Now, I have managers which operate on the other object types. Business logic is in the managers. Data is elsewhere (generally).

RE: Refresher for newbies (part 2)
Thanks Rick for the example. It has really helped me as I am certainly a noob. I'd love it if you (or anyone) could clarify something for me. Firstly, some basic info on my system: I have system wide settings including an SMTP server and a list of users that can access the system. These are stored in a SystemSettings class. I took your advice and used a DispatchAction for system-related updates. I called it SystemAction. It contains 2 methods: setUpForEdit() and edit(). My related form bean contains a dispatch property which defaults to setUpForEdit. This seems to work fine. My system configuration JSP lists users in a select box. Your example lists users as static text with an edit link for each user. This allows you to use c:url to figure include the user ID. However, I have one edit link next to my select box. I understand I have to use javascript to set the user ID and then submit / forward to my user JSP. My questions are: 1. Is there some standard way of handling this with struts / other tag libraries? 2. Assuming not, I would like to develop my own (I will have a lot of select boxes with add / edit / delete links alongside them in my application). Would this be possible, given the reliance on embedding javascript and knowing what parameters to pass to the target page? I know these are kind of general questions but I'm finding it hard to be more specific since I am such a noob. Hopefully you'll be able to confirm that what I'm attempting to do is fairly common and maybe point me in the right direction. Thanks, Kent -Original Message- From: Rick Reumann [mailto:[EMAIL PROTECTED] Sent: Friday, 8 July 2005 1:45 AM To: Struts Users Mailing List Subject: Re: Refresher for newbies (part 2) After reading the initial newbie post, you then might come across a situation where you need to have some things like lists on the page that aren't related to your ActionForm. For example, in the User example just given, imagine you need the person using the form to select a Department that the user belongs in. You thus need a way to make sure that a List of department is available on the page for the user to select from. Now before we get a ton of responses about how here's why I came up with this for Struts, and here's my solution..., I understand that many of the ideas that many of you have come up with our very ingenious and very practical once you understand the framework. I believe, however, for someone new to Struts that it's better to Keep Things Simple and keep things fairly consistent with what they are used to. For this reason I suggest you do things this way In your DispatchAction simply provide a prep( HtttpServletRequest request) method. In there you simply do any preparation of things your form might need. *NOTE* *NOTE* NOTE*: This is NOT, NOT, NOT where you do things like populate the form with user information etc. This is only where you would do things like provide lists for drop down so they are in scope. The next more advanced question is well what happens if you are using validation and validation fails, how are these going to be in scope? I believe the answer is quite simple... just call validate from your Action class versus relying on Struts to call it based on your struts config setting! I have more on this here http://www.reumann.net/struts/articles/request_lists.jsp The benefit to the prep() and the calling validate manually is everything is quite simple... you are using a standard DispatchAction which is easy for people to understand PLUS everything is all in one place. When dealing with editing Users you can look in your UserDispatchAction and see what's going on. No need to look at a bunch of xml config settings, AspectJ inserts, or some other hidden stuff. Granted yes, the newer frameworks handle all of this more gracefully, but the problem is not that big of a deal with Struts. I've written some pretty complex applications and the above has been working fine and it becomes so simple to do. -- Rick - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Which request is used in automatic Validation when the requirements aren't met?
Thai Dang Vu wrote: Perhaps I stated it unclearly. I am using automatic validation, not manual validation (which uses validate method of the form bean). If the requirements aren't met, Struts will lead us to the input page (in my case the /WEB-INF/provider/addprovider.jsp) without going to the execute method of the AddProviderAction class. So my question is: is there any place I can interrupt the request before the addprovider.jsp appears and displays the errors (I use html:errors/ in that page)? You weren't unclear, but Jeff's response was correct. He pointed out that your input can be an action, which can then do whatever you need, instead of a JSP. You just need to change your action mapping so the 'input' attribute names the mapping for your AddProviderAction rather than pointing at a JSP directly.
