RE: Handling Date objects in ActionForm gracefully
Since I just wrestled greatly with this particular beast, my $.02 follows.
Subclass whatever flavor of ActionForm you use, and give it a method with a
footprint like-
java.util.Date StringToDate(String)
{
}
This way you can do something like this in your action:
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception
{
Myform mf = (Myform) form;
BizObject bo = new BizObject();
String dateText = mf.getDateString();
bo.setDate(mf.StringToDate(dateText);
// etc
}
This works very well unless internationalizing your app because the converter
needs a DateFormat defined to read the String correctly. And I am, so I need
to come up with something.
I don't suppose there is a version of BeanUtils that lets the user pass a
DateFormat into copyProperties :-)???

I also suggest this approach to keep the date as string
during posts and convert them to date object when porcessing
the entered dates, surely not in the Form.
Depends on what you really want to achieve. Would suggest
the KISS rule..:-)

DynaForm Type Conversion
I have a bean I persist with Hibernate. It's properties are: 2 Floats 1 Integer (the key) 2 Dates Now, relying on my handy dandy copies of Struts KickStart, Struts In Action, and all of the Web, I'm apparently supposed to declare these methods in the Form I am using as Strings since automatic type conversion can fubar them. But Since the JSP I am using is getting these fields with html:text fields, I apparently am supposed to have methods in form to do the type conversion for me. Okay, that's light years better than putting this in the business layer, but fine. Is there an Automatic way I can get a DynaBean to do this for me? Maybe a Get (prop, type) and get(prop, type, value) for the types youd find in java.lang? If not, there should be, because it limits what a DynaBean can do in a big kinda way. Why have a type declaration in the DTD if youre only ever going to want to use String and String[] ? :-) I mean, it's not like I couldnt add such a set of methods to my DynaValidatorActionForm subclass, but what I'd want is for the framework to use them for me without me needing to know about it. (I dont ask for much, do I???). If not, I'd like to continue to use my Subclassed DynaValidatorActionForm anyway, but I am wondering if it is going to be self-defeating to declare custom getters and setters for properties that are declared in struts config? Should I just use it as a non-dyna form? Maybe I've been up too late (okay, I have) but it's the little things like this that makes me feel like Struts is creating work for me rather than saving me from it.

Re: Dynaform Type Conversion
Well, I was using copyProperties...or rather I\'d want to. I\'m just trying to avoid having to declare my Transfer Objects the hard way. Say I use Mark Lowe\'s idea of the Nested Form Bean (makes sense in alot of ways), but I want to do it dynamically. i.e. DynaForm A has a List property of what will be a bunch of DynaBean B\'s. So riddle me this, how do I instantiate a DynaBean myself as it is defined in the struts-config.xml? When it\'s passed in to the Action as the form, it\'s all prepped and ready to go. If I instantiate an instance of the class myself, it\'s got no dynaproperties. I know BeanUtils will provide functionality to do this, but I would hope there\'s an exposed method that does based straight out of the contents struts-config. Does Struts provide a method where I provide it the name of the bean defined in the struts-config.xml and it return me an instance of the appropriate class, with all the dyna properties set up? -Joe -Original Message- From: Hubert Rabago [mailto:[EMAIL PROTECTED] Sent: Thursday, March 25, 2004 8:38 AM To: Struts Users Mailing List Subject: Re: DynaForm Type Conversion Take a look at BeanUtils.copyProperties. By default, though, it doesn\'t support conversion of dates, since it wouldn\'t know how you\'d want your dates formatted. Check the archives of this list, there\'s been some discussion on that. Another archive you can check is that of the commons-user list. If you\'re looking for further reduction in code, take a look at http://www.rabago.net/struts/formdef which I\'m working on. It\'s alpha, but an initial release is coming real soon (and I\'m looking for folks to help me develop/maintain it). I believe the Struts dev team has plans to include functionality like this in a future version of Struts. For now, we either make do with BeanUtils, or do the conversion ourselves, or through third party plugins like what I\'m working on. If you feel strongly enough about it, you can rant some more on http://nagoya.apache.org/bugzilla/show_bug.cgi?id=27321 though like I said, the dev team has plans for supporting this functionality in a future version.

Re: There *has* to be an easy way to do this..
In a word, Doh! I'm using a DynaForm, and frankly, wanted this as a form property, but well...Let's just say I was brainwashed by my previous paradigm. Rather than using a List in the dynaform, I'm going to create a bunch of String[] properties. Not even so much for the decoupling aspect (which isn't AS big of a deal as it usually is because this JSP by definition is going to be a maintenance screen for this particular Object regardless) but I'm going to need sic the validator onto the fields on the screen, so string arrays it is. JOC, is it kosher for me to be setting the form properties in the Action that leads into the JSP, or should I be doing it somewhere in the form's class. (This seems like a basic question, but in the home grown framework I was raised on, this concept was a bit of a no-no. Much like chaining actions is in Struts.

Re: SV: Form Validation
Check the Bugzilla. I believe it works in the html:errors tag, but you
won't get a javascript popup.
If memory serves, there's a security concern about using minlength in
password fields -- basically the logic goes something like, Do you really
want to be providing a front end validation that tells a cracker how long his
randomly guessed password attempts must be.
If you *really* want this though, you can just go ahead and modify the
javascript you'll find in the validation-rules.xml file.

RE: [OT] Looking for junior Java/Struts developers
Herndon is a pretty sweet place. I used to work in Reston, actually on the top floor at Reston Town Center, and that area is tops. It sure does beat this place that I'm at now, hands down! A salary of $50K would be pretty meager living though, especially in that area. You'd most likely have to live elsewhere and commute. I grew up in Reston (and you've made me nauseous by calling it tops! tyvm :- ). I mean, any place that has zoning laws telling you you cannot paint your house the color you want, can fine you for not mowing your lawn, has outlawed street lights and tells McDonalds it cannot have Golden Arches, and that Convience Stores must not face the roads (all in the name of keeping property values up), it a little bit up uptight for me. Anyway, I live in the area still. To give people an idea of price points: Fairfax County VA is a Washington DC suburb and has gone through a huge population growth in the last few years. Something like 1/9 of all the people in the entire state live there. Fairfax is ranked like #3 in the US for median family income, and has housing prices to match. It's no San Francisco, but still pricy. Rent on a nice single family home costing $2000 a month is probably only a little on the pricy side for the area, and certainly isn't outrageous by local standards. What's affordable in the area? Money Magazine recently rated Sugarland Run, a community about 10 miles away in Sterling, VA as being one of the best places to live in the US because it had good schools (by US stds), near Civil War landmarks, more or less reasonable housing prices for the area, and proximity to good employment. TownHomes in this community run about 150-170K, Single Family Homes push 300K and thats after a *significant* run-up in the last few years. On the plus side, you can by a Camry for the low $20K range I believe, and gas (like all places in the states is cheap) cost me $1.69/gal for regular the other day. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

5. I have html:errors property=errors.required / in the JSP.
My error messages never appear if I call any method other

DynaFormBean property list retrieval
Based upon choices the user makes, he finds himself at a one of four possible screens with fields for him enter. Once he enters his stuff, I take the data and then, using BeanUtils, dump it all into a nicely formatted string and email it. The data all comes in on a DynaValidatorActionForm- All four screens use the same form, just displaying a various subset of the range of possible properties). All four screens send the user into the same action. My problem is that the properties of the dynabean don't come in any logical order. By logical, I don't mean sorted alphabetically or some such. I want them in the order that makes sense for them to appear, which is the order that they appear in my struts-config. The Map returned by form.getMap() doesn't give me what I want. The array of DynaProperties returned by form.getDynaClass.getDynaProperties() isn't in the order I want either. How do I get back what I told struts at config time? Do I need to declare set- properties in struts-config to tell me the order and sort it myself? I'd be surprised if I was the only one with this problem. Ideas?

RE: DynaFormBean property list retrieval
Scuse me, I *wanted* to use BeanUtils. It doesn't do this though. I've tried two ways of doing this. 1) Getting the keySet from form.getMap() and using an iterator from it to get the corresponding value from the form.getMap() 2) Using the getDynaClass.getDynaProperties() method of my dynaform, and adding each of the DynaProperty.getName()'s into a Vector or List, so I can use the same code from 1) that gets an iterator. The order I get them out seems consistent. Just wrong. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

validate() method???
Just based on instinct. I suspect the problem may be in the
JSP tags vs what errors you are returning. What happens when
you change the jsp to have the html:errors / tag instead?

Hi
I have a problem with the validator framework. The
procedure
I am following is
1. I have code like this in the form
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request){
System.out.println( \The requested operation is
\ + getOperation() );
if( getOperation().equals( \showRuleByStatus\)
|| getOperation().equals(
\addRule\)
||
getOperation().equals( \showRuleDetail\) || getOperation().equals(
\init\)){
return new ActionErrors();
}
return super.validate( mapping, request );
}
2. My form extends BaseValidatorForm extends ValidatorForm
3. I have
plug-in className=\org.apache.struts.validator.ValidatorPlugIn\
set-property property=\pathnames\
value=\/WEB-INF/validator-rules.xml,
/WEB-INF/rule_validation.xml\/
/plug-in
in the config.
4. I have bean:message tags and resource properties file which is
working.
5. I have html:errors property=\errors.required\ / in the JSP.
My error messages never appear if I call any method other
than those
mentioned in the validate method.
What could be the problem ?

Re: Validator
Mohan-
This means that Struts is unable to find the definition for errors.required
in your Message Resources.
I suspect it's going to be something on this order. Cant find the file. The
Locale it's using isn't the one you specified. Something like that.
Based on my experience, I'd suggest double checking that the property file
with the messages is actually in the location Struts really thinks it is.

Re: JSP to static html...
I had a requirement like this once, but the reports were generated by Seagate Crystal. It generated the static HTML. JSP seems like the wrong tool to be using here. I would think (speaking out of my hat here) if the report itself was a JSP page what you MAY be able to do is something like, in your action, making an HTTP request yourself to the JSP, receive the HTML that gets generated in response into a text buffer, save it some place, and then send the user to it. If he pushes the button, you have an HTML file you can send him to. It's a complete and utter hack, but hey. - Original Message - From: Jacob Wilson To: Struts Users Mailing List Sent: Friday, January 23, 2004 12:30 PM Subject: JSP to static html... Hi All...

RE: Action to JSP
Craig, I agree with everything you said, but would absolutely love a clarification from you on the following: Other folks will disagree with me on this, of course, but in my general response is show me where the back button and bookmarks window are in a Swing app, and I'll make them available in my web app. :-) I share your philosophy about how web^H^H^H applications should work, but there's a place where this philosophy abandons me. So I respond: If it's supposed to work like a swing app, then get rid of the bookmarks window and back button. Either that or make them unobtrusive. And now you know why I hate Web UI design. :-/ As such, this makes me an utter newb for the more esoteric front end issues involving a browser. So since my pre-struts experience put me mostly on the back end of web applications, what would you say are the best options for dealing with these things (struts or not) in a web application? I mean, I don't care if the back button still exists, but I don't want the user cursing my name every time he presses it without thinking about it. I personally _really_ hate it when this happens to me on my bank's site. TIA, Joe - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Please Help - ClassCastException
Not at all.
First off, set(String, String) is predefined for you. You don't need to
create any of that. In fact, what you will find in a DynaValidatorForm is
that your form classes start to get very sparse. Here's really what it could
look like.
public class PostForm extends BaseDynaForm {
public void reset(ActionMapping actionMapping, HttpServletRequest
httpServletRequest) {
// throw new UnsupportedOperationException(Method is not
implemented);
}
public PostForm () {
}
}
In your ActionForm itself, beanUtils would work something like this. All you
need is to get the right formBean object.
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws Exception {
PostForm pForm = (PostForm) form;
// other code you write here
BeanUtils.copyProperties(yourBean, pForm);
// etc
Doing it yourself without beanUtils?
Instead of calling getSender() and having a String returned, you call get
(sender) and it will return an Object (cast it yourself to whatever type
the sender form property really is). I made a base form class with a
getString method that calls get() and does the String cast for me to save the
tediom.
Making sense now?

Well, first off:

set(myPropertyName, myString)

This is the Dyna part of
DynaForms. It's much less tedious IMHO.
In your action, you absolutely want to cast the form

the form variable has no way to know properties are

I think that there are a lot more mistakes in my code
than I originally thought. The root of the problem is
that I do not know how to use DynaValidatorForm. If
you could help me in learning how to code when I am
working with DynaValidatorForm.
1. in my struts-config.xml, I have:
form-bean
name=postForm
type=org.apache.struts.validator.DynaValidatorForm
form-property
name=receiver
type=java.lang.String/
form-property
name=sender
type=java.lang.String/
.
.
/form-bean
2. My PostForm.java is like:
import org.apache.struts.validator.DynaValidatorForm;
import org.apache.struts.action.ActionMapping;
public class PostForm extends DynaValidatorForm {
private String receiver;
private String sender;
..
public void setReceiver( String receiver )
{
this.receiver = receiver;
}
public void setSender( String sender )
{
this.sender = sender;
}
public String getReceiver()
{
return receiver;
}
public String getSender()
{
return sender;
}
.
.
}
3. in my action class (see the code below)
3.1. do I cast the form to DynaActionForm? or I should
cast the form to DynaValidatorForm?
3.2. Can I use the copyProperties() method of the
BeanUtils to convert the form to a bean?
BeanUtils.copyProperties( threadBean, postForm );

}

}
4. the action mapping in my struts-config.xml is like:

Annoying Validation issue
I am passing in an object my JSP page needs in with request scope. Works fine. I'm also using the Validator, which also, individually, works fine. They however, fight with eachother. Here's how: When you use the validator and put a depends=required on a form's select box, the check isn't caught by the generated javascript. It's caught in the validator's back end logic. This would be fine except that said back end logic has no way to know my JSP page needs some things passed in on the request. I'd like to keep it out of the httpSession if at all possible. Is there a place to tell the validator what it needs to do to generate data the page needs before it tries to send the user back there??

Re: .NET: We are just like Struts... only better.
It was left handed bashing. To paraphrase- Bill was announcing .NET when Struts was only a glimmer in Craig's eye. Microsoft is committed to .NET and therefore .NET is Windows. With Struts/J2EE you are at the mercy of whoever develops the implementation of the Servlet Container, et al, or maybe one day does a bad job, or stops entirely maybe. I chuckled at the 2nd line of thought. Most of us consider this a benefit of J2EE Dev. But it also implies this wasn't potentially a problem with .NET and Windows. To para-paraphrase, We ARE the implementation, therefore however it works it how it works. We dont need no stenking BugZilla. Grunt Grunt. Competition bad.. I didn't notice any bashing going on.

Are httpSessions thread safe?
Not sure how OT this question is. My current plan (unless this is bad for some reason, but if so, Ted H should change his example app :-) is to stash the hibernate Session for a user into his httpSession, and reuse it on each request. A Hibernate Session instance isn't threadsafe. I imagine if two really quick http requests got generated out of the same browser, all hell could break out. I guess I want to know if mortals like me need to worry about this. Does Struts (or the Servlet container FAIK) prevent this from occuring, or do I need to ensure this doesn't happen? If so, how? With a token or is there a better strategy? TIA -Joe - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Are httpSessions thread safe?
Yuck. And may I say, Yuck, again?
It's not the Session object per se, as much as it is the particular
attribute I want to store there.
It does strike me that the storage of a Hibernate Session in the
httpSession is a fairly common thing, so I doubt this bites people very
often. It does seem to have the potential to do so.
In the real world why is this not too big of a deal? Or should it be
considered one?
I suppose that unless you've got time consuming requests, or the user
hits some button on the browser twice in rapid succession, it's probably
okay. A token could effectively prevent this type of condition I
suppose.

Synchronizing on the session object may cause you all sorts
of grief...or it may not. It all depends on your container.
The spec makes no guarantees about the identity of the object
returned by methods like PageContext.getSession or
HttpServletRequest.getSession. For example, here's a test JSP:
%@ page contentType=text/plain %
%
out.println(session: + session);
out.println(pageContext.getSession: + pageContext.getSession());
out.println(request.getSession: + request.getSession(false));
out.println(request.getSession: + request.getSession(false));
%
Here's the output from TC 4.1.24:
session:

pageContext.getSession:
[EMAIL PROTECTED]
request.getSession:
[EMAIL PROTECTED]
request.getSession:

And that's just within the same thread! I'm pretty sure TC
4.1.29 does return the same instance, but just remember it's
not guaranteed.

There's nothing in the specs that guarantee threadsafe access to
session attributes.
A pattern I've become quite fond of is to create a single object (we
call it a shell, analogous to an operating system shell) which
encapsulates everything you want in session context for a
given user;
then put just this object into session scope, and use methods on it
to do everything else. This helps you apply synchronization where
appropriate. There's still a risk of a race condition
involving the
initial creation of the shell (assuming you do something like check
the session to see if there's a value under the key you use for the
shell) -- you can put that in a block synchronized on the session
object:
MyAppShell shell = null;
synchronized (session)
{
shell = (MyAppShell) session.getAttribute(SHELL_KEY);
if (shell == null)
{
shell = new MyAppShell ();
session.setAttribute(SHELL_KEY, shell);
}
}
If the shell concept seems like high overhead to you, you
can still
synchronize accesses on the session object along those
lines; you may
just have more trouble keeping track of all the places it needs to
happen.

RE: Are httpSessions thread safe?
I saw these. I just had this grand idea of minimizing the Hibernate
connections by doing what Ted did in his example -- not actually
discarding a user's Hibernate Session until his httpSession expired.
I've never messed with ThreadLocals before but I suspect that the
attempt to put a ThreadLocal into a httpSession I suspect would be funny
to watch.

A pattern I've become quite fond of is to create a
single object
(we call it a shell, analogous to an operating system shell)
which encapsulates everything you want in session context for a
given user;
then put just this object into session scope, and use
methods on
it
to do everything else. This helps you apply
synchronization where
appropriate. There's still a risk of a race condition
involving the
initial creation of the shell (assuming you do something like
check
the session to see if there's a value under the key you
use for the
shell) -- you can put that in a block synchronized on
the session
object:
MyAppShell shell = null;
synchronized (session)
{
shell = (MyAppShell) session.getAttribute(SHELL_KEY);
if (shell == null)
{
shell = new MyAppShell ();
session.setAttribute(SHELL_KEY, shell);
}
}
If the shell concept seems like high overhead to you, you
can still
synchronize accesses on the session object along those
lines; you may
just have more trouble keeping track of all the places
it needs to
happen.

RE: Are httpSessions thread safe?
I guess creating Hibernate Sessions and Destroying them on every request isn't as bad as I imagine it is? I figured creating the session when the user showed up, destroying it when his httpSession expired, and reconnecting/disconnecting on each request was strictly better. I guess doing this isn't quite worth the effort? No one else seems to mind :) -Joe -Original Message- From: David Erickson [mailto:[EMAIL PROTECTED] Sent: Thursday, December 18, 2003 12:27 PM To: Struts Users Mailing List; [EMAIL PROTECTED] Subject: Re: Are httpSessions thread safe?

Subject: Newbie can't get saveErrors() working
Hi folks,
I'm in love with the validation framework included with
Struts. The fact that I can do validation with regular
expressions and have client-side JavaScript created for me
automatically is fantastic.
However, there's one error that I have to catch on the
server-side in some cases: an attempt to create a duplicate
entity. In this case, I'd like an error message to appear
close to the form input for which it applies.
So I'm creating an ActionError in my Action and saving it as follows:
} catch (DuplicateDomainAliasError e) {
ActionErrors errors = new ActionErrors();
ActionError error = new
ActionError(error.domainAliasName.exists);
errors.add(domainAliasName, error);
saveErrors(request, errors);
}
I have error.domainAliasName.exists in my message bundle:
error.domainAliasName.exists=A domain alias with that name
already exists.
Because domainAliasName is a property of the ActionForm
associated with the html:form/ I have in my JSP, I expect
the message to be displayed with the following tag:
html:errors property=domainAliasName/
However, that tag renders the empty string.
Can someone point out what I'm doing wrong here? I can get
the error displayed at the top of the page by using
declarative exception handling, but the page has a lot of
stuff on it, and I'd like the error displayed close to the
form input that it relates to.
Thanks,
Sheldon.

Subject: Very Troubled in Finding Ways to Pass a
Variable to a Class
I have a class FindEditorData.java. I want to
pass a
vairable 'username' to this class for some
processing.
This class is invoked from a JSP:
html:form action=/find/Category
html:submitView Articles/html:submit
and the value of the 'username' is obtained this
way:
String username = request.getRemoteUser();
Due to my limited knowledge in Struts, I cannot
figure out what to do. Let me explain the
problem:
1. This class has this method:
public Object execute() throws Exception { ...
}
I do not make this class extends HttpServlet or
extends Action. I cannot nest a method inside a
doGet/doPost or the
Action's excute().
2. The action mapping in the struts-config.xml is
this
way:
action
roles=editor
path=/find/Category
type=org.apache.struts.scaffold.ProcessAction
parameter=org.XYZ.article.FindEditorData
name=articleForm
validate=false
forward
name=success
path=.article.Result/
/action
I am stuck because I do not know how to pass
'username' to the FindEditorData.java. I cannot
state:
String username = request.getRemoteUser();
or
String username = (String)session.getAttribute( EditorName );
because the FindEditorData is not a servlet and
does not extend Action.
I cannot pass a hidden variable from the JSP
because I
do not know how to retrieve the value of a hidden
variable in a Java class.
Need clever ideas. Please help.

pass a
vairable 'username' to this class for some
processing.
This class is invoked from a JSP:
html:form action=/find/Category
html:submitView Articles/html:submit
and the value of the 'username' is obtained this
way:
String username = request.getRemoteUser();
Due to my limited knowledge in Struts, I cannot
figure out what to do. Let me explain the
problem:
1. This class has this method:
public Object execute() throws Exception { ...
}
I do not make this class extends HttpServlet or
extends Action. I cannot nest a method inside a
doGet/doPost or the
Action's excute().
2. The action mapping in the struts-config.xml is
this
way:
action
roles=editor
path=/find/Category
type=org.apache.struts.scaffold.ProcessAction
parameter=org.XYZ.article.FindEditorData
name=articleForm
validate=false
forward
name=success
path=.article.Result/
/action
I am stuck because I do not know how to pass
'username' to the FindEditorData.java. I cannot
state:
String username = request.getRemoteUser();
or
String username = (String)session.getAttribute( EditorName );
because the FindEditorData is not a servlet and
does not extend Action.
I cannot pass a hidden variable from the JSP
because I
do not know how to retrieve the value of a hidden
variable in a Java class.
Need clever ideas. Please help.

I was writing to you about that but you found your solution faster than I could type (my poor aching fingers at 2AM!). When you said your 'formName=UserLoginForm', that suggests you're keying off the action's ActionForm name 'name='UserLoginForm' for your validation. That's why you would use DynaValidatorForm. Using DynaValidatorActionForm is just like a DynaValidatorForm with one exception: it validates of the name of the action. So if your action is called /edit.do, it would need a form name of '/edit' such as: form name=/edit field ... ... /field /form I also got stuck on this when I first started using the Struts Validator.

Struts Developed Sites and Google
URL's with session state information will cause search engines problems in trying to index the content. (Makes sense -- the generated URLs wont be valid for anyone else). Google isn't about to store cookies as it indexes content, I'm sure. So doesn't this make Struts a poor choice for developing a site when Search Engine visibility is important? As I understand it, if your client doesn't support cookies, you will get a jsessionid in your urls, which is the embodiment of the above scenario.

RE: DynaValidator can't get validation to work
Marc, I'm doing largely the same thing as you are and having a bit more success, but not complete success. Some thoughts: 1) Are you *really* sure that validator.xml is loading? Your depends=required,minLength makes me wonder since the identifier is really minlength. 2) I can't get minLength to work for password fields at all. Yes, it's not supposed to generate javascript for it (so BugZilla says), but I don't even get a backend validation error. (Anyone able to explain this???) 3) dynamic=true is deprecated. You using struts 1.1? 4) Put an html:errors / tag on the page at least to test with for now. If the JS works, at least you'll know that youre not going crazy. I'm using Hibernate too.

I have used the debugger to step through the chain of events. In org.apache.commons.validator.Validator in the validate method at line 577, it returns null for the form. As far as I can see, this means that it doesn't get any validation rules for the form from the framework. I also noticed that some locale issues with the validator were reported on Bugzilla . My locale is nl (for the Netherlands). Could this be it? I tried adding the locale and country variables to my formset key in validator.xml. To no avail. Any ideas? I'm getting a bit desperate here.

RE: Hibernate plugin
Scuse me. I typoed. I meant to say, Havent shut me down cold. The
happen, and I'd like to know why, but for now, I'm not complaining.
The reason I didn't go to the Hibernate site (don't laugh too loud) is
that I had problems getting the one from the hibernate site to work too,
and there are things in the struts hibernate example that 1) Need it and
2) I don't feel confident enough to mess with.
Specifically, it uses a DispatchAction class, but defines execute() to
do all of it's hibernate related stuff (again, which I don't feel I
understand terribly well). I scratch my head every time I see this. Why
would you have execute in a DispatchAction? Does it get called before
you do super.execute()?
I'd prefer to go to the one from Hibernate if I knew what I was doing
better :-/

So I googled (imagine!). This changed since in the final release, to be part of struts-html.tld, did it not? If so, can errata get posted to Manning's site? I tried to report it on Author Online, but couldn't reach it. See, without newbies like me, what would you guys do? :-) -Joe - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

So I googled (imagine!). This changed since in the final release, to be part of struts-html.tld, did it not? As I understand it is in org.apache.struts.resources and it is called validation_1_1.dtd So why you have to copy in WEB-INF? Do not use books without thinking about it! I think the point is that, wherever it wound up, the usual config brought it along for the ride, but you raise an interesting point -- does validator-rules.xml need to go there (again like the book said) or are you saying that's wrong too? One way or another, errata is needed. I think youre mistaken about something though. Without googling, reading a book, or asking here, what set of thoughts would have made that particular factoid clear to a new struts user? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
JBuilder Servlet path issue
I'm using JBuilder 8 Enterprise and Tomcat 4.1. Whenever you use JB to build a servlet application, it defaults to building the project such that the root directory is named after the project itself. This is especially annoying in struts as I'm finding I need to name all my actions /projectname/ActionMappingName.do Anyone have experience with how to get JBuilder to let me have the root tree for my web app, or if there is a way to make a generic prefix for my ActionMappings?

RE: how to create an error message with a filter
Suggestion: In your filter, stick the current timestamp as an attribute in the httpSession. Before you do that though, check the timestamp that got stuck there on the last request. If the delta threshold, bounce the user to the right page. If you *really* wanted, you could generate an ActionError inside of the filter I suppose, so the login page displays the reason he wound up there, but I've never tried that, and my newbie self kind of shudders at that. -Joe -Original Message- From: Arne Brutschy [mailto:[EMAIL PROTECTED] Sent: Thursday, November 20, 2003 4:11 AM To: [EMAIL PROTECTED] Subject: how to create an error message with a filter Hello, I want to create a error message with my authentication filter. The filter checks for an idle timeout. If this occours, it invalidates the session. At this point, the filter should create a error message, i.e. you have been idle for too long!. After that the filter redirects to the login jsp (as always if the session is not valid). The jsp page should use the common struts tags, to display this error message. How can I do this? how can I store such a message in my request? How can I forward that to my redirect?

RE: JBuilder Servlet path issue (solved)
The directory JBuilder makes is named after the WebApp, (which isn't necessarily the project name, but it was for me (and probably your colleague). The WebApp Name is actually optional. RightClick on the node for the WebApp, select properties, clear out the name field and press the Okay Button. (For a new WebApp, just don't name it to begin with) You'll see node for the WebApp in the project tree will now say Default WebApp instead of the name you had before. The behavior will be what you expect. I'm glad it wasn't such a newbie question after all. I kinda felt like an ACE Certified Mechanic who couldn't get the hood opened. -J -Original Message- From: James Neville [mailto:[EMAIL PROTECTED] Sent: Thursday, November 20, 2003 4:56 AM To: Struts Users Mailing List Subject: Re: JBuilder Servlet path issue (solved) Joe, If you have any tips on how to configure this, I have a colleague experiencing the same issue.

RE: Large scale Internationalization using struts
The problems/questions I can see are: As a single textfile is used, when there are several thousand entries it will become difficult to manage. Can updates be made, during operation, to the content ? What happens if a user requests the files content while it is being edited ? Why would a large web site be configured such that maintenance happened in such a fashion?? Is the textfile cached for performance, or will concurrent calls compete for the same file-resource ? I would *think* it's loaded at servlet.init() time, but that's me guessing. Like you say, for performance reasons, I'd kind of hope so. Should be easy enough to test. As I'm probably not the first person who is trying to use Struts on a larger scale for internationalization issues I thought someone might have a better solution. Suggestions ? In this case, you shouldn't be putting everything into one file. I'd be creating message bundles that corresponded to various sections of the web site. If nothing else, it's easy on the CM System if you've got a lot of developers. -Joe - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Utter Newbie Question
I'm making using struts for more or less than first time. I read the FAQ on how to handle logins to an application and I'm left with one question: Why stop a storing a Boolean in the session to determine logged-inness? Why not just store the (validated) User object in the session and check for it's presence? That way, if it's there, one can utilize the data in the User object for whatever sordid little purpose said developer comes up with. Is this a good idea? If so, how do I go about doing this in the view? (I told you I was a newbie!). I mean using bean:write tags of the User object seems straightforward enough, but what about the List of Children objects that is part of the User object?
