ActionErrors problem...
I have this in my code:
errors.add(ActionErrors.GLOBAL_ERROR,
new
ActionError(error.key.invalid-value.dummy,keyname,value,expected);
I have this in application.properties:
error.key.invalid-value.dummy=DUMMY: key:{0} Value:{1} expected:{2}
However, using html:errors/ in my page, the only thing that gets
displayed is:
DUMMY: key: Value: expected:
i.e. the replacement values I give are swallowed.
Any idea on what I am doing wrong? I tried calling new ActionError(..,a)
where a is an Object[] with the values I want. This did not work either.
I imagine I must be missing something obvious...
Thanks for any hint...

Problems with modules and message resources
I have an application that has used bean:message for quite some time. I have had multiple struts-config files and each one defined message-resources that it needed. This all worked correctly I just changed my application to use Struts Modules. I confirmed that I have everything working correctly with tiles and my navigation, but when I use a bean:message tag that references a message-resource definition in one of the module config-files, I get an error stating that Cannot find message resources under key managementMessages Where managementMessages is the name of the key in the message-resources declaration The page being rendered is in the same Struts Module that the message-resource being requested is defined Also, If the bean:message tag references a message-resources in the default module, then it works correctly Anyone come across this before? I am ready to ditch modules if I cannot get this working. Thanks __ Do you Yahoo!? Protect your identity with Yahoo!

Re: validation occuring before form is loaded, why?
On 11/17/2003 08:04:21 PM Janice wrote: Hi Gang, I was having problems getting validation to work at all. I've read every post on getting it to work, followed all step-by-steps, and nothing would ever do it. Today I yanked all the .jar files out of my lib directory and updated it with the .jar files from the latest release version of struts (1.1). Well... something started to happen all right, just not what I expected. What it looks like its doing is validating my form before its even loaded (execute() does not get called, and my print statements in validate() show that super.validate() is returning errors.) What my code is trying to do is: 1) a list of widgets are displayed. Each widget has a link to an edit page. There is also an add widget option. Both the edit and the add call the same action with a request parameter like addEdit=add or addEdit=edit. Just keeping it simple, you've got something like this? displayWigetsAction (mapping validate=false) -- displayWigets.jsp user clicks add button or edit link -- setupAddEditAction (mapping validate=false) -- addEdit.jsp user submits form -- saveAddEditAction (mapping validate=true) Susan Currently, when either of these links are clicked, I get a 'page cannot be displayed' and my log tells me that there was a validation error. I don't know why validate() is being called in the first place, I have no explicit calls to it, and didn't expect it to get run until the next form was submitted and my struts-config.xml said validate=true. 2) the next step should be that the action builds the form object with either the reset() values for an add, or a database-retrieved set of values for an edit. Ideally, when this form is submitted, the form should be validated. If I change my validate() method on my form object to return a new ActionErrors(), then things work better, but still don't validate. I hope this is enough information. I can post a bunch of code if its not. I really appreciate any and all help, this validation stuff is taking s long to get working!

ModuleConfig Question
Hello all, I have been asked to create an Action that would dynamically modify struts-config.xml and ModuleConfig in order to avoid restarting the app server to read the new struts.config.xml. I did some research and looking at the code in the ModuleConfig implementation, it always checks the value of the configured flag, if it is set to true, no modification is allowed. My first question: is what I am trying to do possible?? if the answer is yes, how would I go about accomplishing it?? Here are my thoughts. First, I have to create my own implementation of ModuleConfig that allows modification after the initial setup. Next, I have to let struts use that implementation. That can probably be done by using the ModuleConfigFactory class. However, how do I make struts pass my class instead ofthe default implementation to the Factory?? I came across a message that mentioned something about adding a parameter to web.xml which specifies the implementation class for ModuleConfig but that is not in the current release. Any help/advice/insight into this will be greatly appreciated. Thanx. - Marwan - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Different session handling between websphere and tomcat
Hi, I´m running Struts 1.1 with Tomcat 4.1.24 and also with Websphere (wsad) 5. I have a tiny application developed under wsad running fine under tomcat. When I try to deploy the same app to websphere I´m constantly getting nullpointer exception for the objects I try to pass from my action class to a jsp via the session (session.setAttibute()). After a search at google and list archives I found out that lots of guys seem to have kind a problem like this. It seems that in websphere I get a new session (I checked it with session.geId()) every time I call my jsp. The session I added my object to as a session attribute is not reachable anymore. I also detected that tomcat is passig the session id via the url like this: http://myserver:8080/myJsp.jsp;jsessionid=DSFSD98DFSDF... Websphere just calls: http://myserver:8080/myJsp.jsp I didn´t find a workaround for this problem yet! What is the recommended way of passing an object (not necessarily a bean, in my case a collection) from an action class to a jsp? Is this a configuration or an programming issue?

If you do not require the collection after the page is rendered, you could put it into request scope. This is what I do to populate listboxes, tables, etc..

Re: jsp:include'd struts action closes stream, and thus breaks page
I found that Tomcat bug 21440 regards this. Basically JSP included pages have direct access to the out stream, an naturally this is transparent to the included page, so the struts framework closes the out stream (prematurely seen in perspective of the including page). Any suggestions for alternative include mechanims? Any interesting taglibs out there that does this in a more predictable manner? Thanks, Morten Morten wrote: Hi, running Tomcat 4.1.27.

I don't know if you can directly link to a tile, because the web container will still need a way to get to your tile from a URL.

RE: validation occuring before form is loaded, why?
Hi. 1.What version of struts are you working with ? 2.If the action map's validate attribute is set to true, the form.validate() method is called *before* the action is executed. If there are errors it will forward back to the input page (value of the input attribute). 3.To avoid having struts call validate for addEdit=add, you need to either (a) forward to a different action that has validate=false or (b) check the value of addEdit in your form and don't call the super unless its 'edit', or (c) use one action map for add and edit and another for submitting the changes (the latter is the one that should have validate=true). Note that you can have multiple actions can be mapped to the same action class. HTH, Rich -Original Message- From: Janice [mailto:[EMAIL PROTECTED] Sent: Monday, November 17, 2003 8:04 PM To: [EMAIL PROTECTED] Subject: validation occuring before form is loaded, why? Hi Gang, I was having problems getting validation to work at all. I've read every post on getting it to work, followed all step-by-steps, and nothing would ever do it. Today I yanked all the .jar files out of my lib directory and updated it with the .jar files from the latest release version of struts (1.1). Well... something started to happen all right, just not what I expected. What it looks like its doing is validating my form before its even loaded (execute() does not get called, and my print statements in validate() show that super.validate() is returning errors.) What my code is trying to do is: 1) a list of widgets are displayed. Each widget has a link to an edit page. There is also an add widget option. Both the edit and the add call the same action with a request parameter like addEdit=add or addEdit=edit. Currently, when either of these links are clicked, I get a 'page cannot be displayed' and my log tells me that there was a validation error. I don't know why validate() is being called in the first place, I have no explicit calls to it, and didn't expect it to get run until the next form was submitted and my struts-config.xml said validate=true. 2) the next step should be that the action builds the form object with either the reset() values for an add, or a database-retrieved set of values for an edit. Ideally, when this form is submitted, the form should be validated. If I change my validate() method on my form object to return a new ActionErrors(), then things work better, but still don't validate. I hope this is enough information. I can post a bunch of code if its not. I really appreciate any and all help, this validation stuff is taking s long to get working! Thanks in advance, Janice

Array of html:checkbox / html:multibox not retaining state after validation
Hi, I have a scenario where I have an array of checkboxes along with other data displayed in a table format on a JSP. I have to keep track of which checkbox is checked or unchecked when a user submits the form. I use the validate() method of my ActionForm to do validation. However, the values of the checkboxes are not retained when a validation error occurs. I have tried the following in vain: a. Array of html:checkbox I have used a boolean array for the form data type corresponding to the checkbox. Also, I set all the values of the boolean array to false in the reset() method. b. Array of html:multibox In this case, I have a String array for the form data type, and the array is not populated initially. The value of the html:multibox is obtained from a bean stored in the session, i.e html:multibox property=formProperty value=%=someValue% /html:multibox which is inside a logic:iterate loop. Also, in the reset method of the form, I set the value of the String array to null (this has worked for me in the past). I'm not sure how to set the array length to 0. Unfortunately, both of the above approaches don't help in retaining the states of the checkboxes when a validation error occurs. I also tried using Javascript to populate a hidden variable with the values of the checkboxes on form submission, and setting the checkbox array with the hidden variable array when a validation error occurs. This didn't work either. Could somebody tell me what I'm doing wrong? Any help/pointers will be greatly appreciated. Thanks, Shyam __ Do you Yahoo!? Protect your identity with Yahoo!

(obviously, i can just specify a php page instead of a jsp, but how do i get dynamic data without relying on the jsp tags?) As soon as you leave the Java world, the only means of passing dynamic content is the 'traditional' way, i.e. parameters. You lose everything from page to application scopes and won't be able to use attributes (Objects) in particular, as those reside inside the VM's memory and thus are inaccessible from PHP. If you absolutely have to pass complex information between the PHP app and the Java part, one possible suggestion might be to use a database or other third-party serialization target both of them can access (in lack of a database, an XML file, perhaps). Generally, I won't recommend this, for there may be all kinds of synchronization and security issues involved. Don't know if PHP can handle this, but this also might be a situation where Web Services may be helpful. Anyway, the overhead involved in both cases is much too big for a private site. IMHO it's better to look for a Java-based blog solution. is this incredibly easy? impossible? is there some weird chaining process that i have to go through? or is there another blogging tool which doesn't use php which i should use instead? Admitting I kind of hate both blogs and PHP in general, I'm still pretty sure there are Java-based blog solutions around.

Complex Form Validation
We are trying to perform some complex form validaion with the new Validator plugin. Here is what we are trying to do: 1 -- validate a form field based on other form fields 2 -- validate a form field based on div style settings I know that I could solve the first problem with the old validation architecture, but is there a way to do that through the validator.xml? I'm not sure about the second problem. The code looks something like this div id=myDiv style=display: none //my form element here /div So is it possible to only validate the form element above only if the enclosing div display is block? I've looked, but couldn't find anything explaining how to go about this. Any ideas?

Re: Complex Form Validation
George,
I have done something similar to this. I haven't looked at browser
compatability yet(we're currently using this with ie6), but the concept
that I use is that I look at the parents of the form field, trying to find
out if the element is hidden. If I find that a parent that is hidden, then
I take appropriate action.
My javascript loop looks like this:
var hiddenParent = false;
for(parent=formField.parentElement; parent != null hiddenParent ==
false; parent = parent.parentElement) {
if(parent.currentStyle.display == none) {
hiddenParent = true;
}
}
if(hiddenParent) {
etc, etc
}
Hope this helps a little. If there are better ways to do this, I'd love to
get the feedback :-)

Re: Complex Form Validation
Nick,
Thanks for your response. I'm doing something similar with javascript. What would be
better is if we could validate the form serverside with the validation framework... I
think we would have to write a custom validator that somehow would get the div parent
of the form field and check that before checking the actual field.

RE: Complex Form Validation
George,
You can't do the validation server-side as you proposed because the browser
only sends HTML form elements. It will not send any information regarding
the div tag. You would have to have a hidden form variable and use
JavaScript to populate it with any values of interest when the form is
submitted.

Richard

Re: Disable URL-rewriting?
First, check out a tutorial on Servlet 2.3 filters. One at: http://java.sun.com/j2ee/tutorial/1_3-fcs/doc/Servlets8.html Essentially, it'll boil down to creating two classes: a filter (implements javax.servlet.Filter) and a response wrapper (extends javax.servlet.http.HttpServletResponseWrapper).

Re: Disable URL-rewriting?
Am Dienstag, 18. November 2003 18:29 schrieb Brice Ruth:
If anyone knows a solution to this matter, I'm definitely interested
in hearing about it, too. From all what I can tell, some search
engines don't care (Altavista's Scooter, for example), while
some do (Google, in particular) and go away when they detect
a session. I experimented for quite some time, but to no
real avail. One approach I tried is having a custom action
explicitly killing all sessions when entering the main page
and invoking that one from my index.jsp. This works, but
I couldn't keep to this approach when porting (my private
site) to Tiles some time ago, didn't look further into the
possible reasons behind this. Plus, Struts also stores
some info in session scope, the user's locale, for example.
When I had to decide between sessions and Google
(in fact, I only need sessions for pages 'beyond' authen-
tication stage; my provider doesn't grant me access to
resin.conf, so I had to write a filter for that task), I decided
to better stick to the framework and have Google satisfied
otherwise (ah, robots.txt doesn't make any difference
in this direction, too). Gone bad already, I chose the
cloaking approach (don't try this at home :-), so I changed
my index.jsp to something like:
%@ page contentType=text/html; charset=ISO-8859-1 session=false %
% String userAgent = request.getHeader(User-Agent);
if (userAgent.indexOf(oogle) == -1) { %
jsp:forward page=/main.do /
% } else { %
jsp:forward page=/static/index.html /
% } %
and just saved a static snapshot of the main page in
/static with Cookies enabled, so the jsessionid things are
not appended to the links. Google won't be able
to tell the difference because of the forward.
Considering 'brute' means as disabling URL
rewriting in general, I'd rather guess this is a
server-specific thing. In Java, you don't have
any means of telling the server how to maintain
session state, the only thing you can say is
'request.getSession()' and check for an existing
session if you give 'false' as a parameter to
the overloaded version, and you can
programmatically kill sessions via
session.invalidate(). This is all Struts can do,
too. So I think you have to check your
server's manuals on this matter. If it's Tomcat,
I can rather reliably tell that you can decide
whether to use cookies or not, but the same
is not true for the URL-rewriting approach
as a 'fallback' means, and then, the server
has to adhere the Servlet specification, after
all. Now. As you can't determine *how* sessions
are maintained, you can still determine to some
degree *when* they're created. One thing I
can tell from my experiences with Struts is that
using the standard forward Action will auto-
matically result in having a session around
afterwards, but if you write a custom one
that just says 'return mapping.findForward(success);,
things are quite different. And so on. I really
have to look further into this if my time allows.
Note this is just telling from my experiences
when developing my private site. On the
job, the landing sites usually are static
HTML pages, not so much because of
session handling or search engines,
but because of the general vulnerability
of dynamic pages to DoS attacks and
high traffic volumes in general.

Is there any way to disable URL rewriting (with jsessionid) in Tomcat

Re: Disable URL-rewriting?
Got it.
Simple as pie, actually. Created the Wrapper class, no-op'd the
encodeUrl/encodeURL and put it into the Filter that was already setup to
handle all incoming requests ... piece of cake :)
Sweet!
Here's the wrapper code:
public class StripSessionIdWrapper extends HttpServletResponseWrapper {
public StripSessionIdWrapper(HttpServletResponse response)
{
super(response);
}
public String encodeUrl(String url) { return url; }
public String encodeURL(String url) { return url; }
}
and here's the couple lines I have in my Filter:
StripSessionIdWrapper wrapper = new
StripSessionIdWrapper((HttpServletResponse)response);
and then, instead of passing response to the chain.doFilter, I pass
wrapper
Nice ... clean, I like it.

If it's really just the *.do ending, it's eas to map Struts to *.html (assigning a .htm ending to truly static pages), use mod_rewrite or the rewrite filter available in Resin 3.0. But didn't check all that yet. NAFAIK, but that's by no means definitive. I *do* know that you can configure a TC context (or default context) to do the opposite. In other words, turn off cookies and only use rewriting. Hm, what if you create a filter to wrap the response with an HttpServletResponseWrapper that no-ops encodeUrl and encodeURL? Quoting Brice Ruth [EMAIL PROTECTED]: Is there any way to disable URL rewriting (with jsessionid) in Tomcat or via struts-config.xml or anything? I'm about at my wits end with this jsessionid thing - now our search engine which indexes by crawling the site (and doesn't support cookies) can't index properly because of the jsessionid property ... and frankly, I'm not really caring at this point if the 3-5% of visitors to our site can't use sessions (there's practically no functionality that depends on it anyway - mainly a performance improvement, where it is being used). I'd like to leave sessions via cookies enabled, but disable URL rewriting for sessions. -- Brice D.

Re: avoid proxy-caching by generating changing urls
Hi, I'm using Struts with Tomcat 4.1. If you disable cookies in your tomcat context, all your ULR will be rewritten with a jsessionid. So the proxy issue should be solve. However I don't know If there is a way to enable cookies AND be sure that the proxy's cache is disable. In my project I use this in all jsp I won't be in any cache : % response.setHeader(pragma, no-cache); response.setHeader(Cache-control, no-cache, no-store); response.setHeader(Expires, 0); % head meta http-equiv=pragma content=no-cache meta http-equiv=cache-control content=no-cache /head It seems to work for me but I'm sure there are more élégant solutions. Using Struts, you see on the bean:header tag. I still haven't found time to explore it. Let me know if it's work for you. Carl Christine Gerstenmayer wrote: Hi all !

Form data vs request attributes
I've been fiddling around with Struts for a while now and am still a little puzzled as to whether JSPs should be getting their data from my DynaActionForm or from the session/request context. For example, if my JSP contains: html:select property=selectedCustomer size=5 html:options collection=customers property=id/ /html:select html:text property=suburb size=16 maxlength=18/ The way I have this working currently is by adding customers to the request context and by having suburb declared in my DynaActionForm. I don't appear to have to declare customers in the form, but if I don't declare suburb, I get an error... what is the difference? P.S. If it helps clarify things, the JSP I have displays a list of customers and some input fields. The user can update the input fields, press submit and they see the same page (with the new details displayed in the list).

Re: initializing properties for Actions
Carl,
That didn't work, but thanks anyway. I also tried changing the data type for
passwordDisabled to a String and have the normal get/set methods but that didn't
seem to change the outcome either.
I think the real problem is that it is trying to call setPasswordDisabled on
org.apache.struts.action.ActionMapping instead of my LoginAction class. Not sure
if this is a known you can't do that or a known bug or whatever (I'm using
struts 1.1.0). I was unable to find any info on this topic either in the
archives or on jakarta.apache.org.

I think have determined that it happens when attempting to process this tag:
% System.out.println (got here);%
tdhtml:text property=city maxlength=50 size= 20//td
% System.out.println (got here2);%
(only the first print statement appears in catalina.out)
I am definately able to find the struts-html taglib (as I am already
inside an html:form tag by this point).
I think I really have a situation where html:form can be found but not
html:text for the following reasons:
Here is the jasper generated code:
67out.write(hr\n\n);
68if (_jspx_meth_html_form_0(pageContext))
69 return;
70out.write(\n);
71out.write(table border=\0\\n);

80out.write(/td\n);

snip .
127out.write(/html\n);
128 } catch (Throwable t) {
129out = _jspx_out;
130if (out != null out.getBufferSize() != 0)
131 out.clearBuffer();
132if (pageContext != null) pageContext.handlePageException(t);
133 } finally {
134if (_jspxFactory != null)
_jspxFactory.releasePageContext(pageContext);
135 }
snip .
154private boolean
_jspx_meth_html_text_0(javax.servlet.jsp.PageContext pageContext)
155throws Throwable {
156 JspWriter out = pageContext.getOut();
157 /* html:text */
158 org.apache.struts.taglib.html.TextTag _jspx_th_html_text_0 =
(org.apache.struts.taglib.html.TextTag)
_jspx_tagPool_html_text_size_property_maxlength.get(org.apache.struts.taglib.html.TextTag.class);
159 _jspx_th_html_text_0.setPageContext(pageContext);
160 _jspx_th_html_text_0.setParent(null);
161 _jspx_th_html_text_0.setProperty(city);
162 _jspx_th_html_text_0.setMaxlength(50);
163 _jspx_th_html_text_0.setSize(20);
164 int _jspx_eval_html_text_0 = _jspx_th_html_text_0.doStartTag();
165 if (_jspx_th_html_text_0.doEndTag() ==
javax.servlet.jsp.tagext.Tag.SKIP_PAGE)
166return true;
167
_jspx_tagPool_html_text_size_property_maxlength.reuse(_jspx_th_html_text_0);
168 return false;
169}
So I am willing to suppose that out.write() isn't throwing the
exception, which leaves only _jspx_meth_html_text_0(pageContext).
Looking into that method, I see 3 candidtates:
_jspx_tagPool_html_text_size_property_maxlength.get(org.apache.struts.taglib.html.TextTag.class);
_jspx_th_html_text_0.doStartTag();
_jspx_th_html_text_0.doEndTag()
_jspx_tagPool_html_text_size_property_maxlength.reuse(_jspx_th_html_text_0);
The question is why does one of these throw a Servlet exception when
form doesnt? Though the form tag hasn't closed yet so it could still be
the form tag, when I misname the taglibrary in the JSP I get a different
error.

Re: problem with html:text bean throwing exception
Have you a vaild formBean define for this html:form in your struts
config file ?
form-bean name=myForm type=org.myForm/
Is this bean called in your action mapping ?
action path=/htmlForm type=org.myAction name=myForm
scope=request validate=true input=/page.jsp
forward name=success path=/succes.do redirect=true/
/action
I've faced a similar issue for these reasons.

I think have determined that it happens when attempting to process this

% System.out.println (got here);%
tdhtml:text property=city maxlength=50 size= 20//td
% System.out.println (got here2);%
(only the first print statement appears in catalina.out)
I am definately able to find the struts-html taglib (as I am already
inside an html:form tag by this point).
I think I really have a situation where html:form can be found but not
html:text for the following reasons:
Here is the jasper generated code:
67out.write(hr\n\n);
68if (_jspx_meth_html_form_0(pageContext))

128 } catch (Throwable t) {
129out = _jspx_out;
130if (out != null out.getBufferSize() != 0)
131 out.clearBuffer();
132if (pageContext != null) pageContext.handlePageException(t);
133 } finally {
134if (_jspxFactory != null)

135 }

154private boolean
_jspx_meth_html_text_0(javax.servlet.jsp.PageContext pageContext)
155throws Throwable {
156 JspWriter out = pageContext.getOut();
157 /* html:text */
158 org.apache.struts.taglib.html.TextTag _jspx_th_html_text_0 =
(org.apache.struts.taglib.html.TextTag)
_jspx_tagPool_html_text_size_property_maxlength.get(org.apache.struts.taglib.html.TextTag.class);
159 _jspx_th_html_text_0.setPageContext(pageContext);
160 _jspx_th_html_text_0.setParent(null);
161 _jspx_th_html_text_0.setProperty(city);
162 _jspx_th_html_text_0.setMaxlength(50);
163 _jspx_th_html_text_0.setSize(20);
164 int _jspx_eval_html_text_0 = _jspx_th_html_text_0.doStartTag();
165 if (_jspx_th_html_text_0.doEndTag() ==

166return true;
167
_jspx_tagPool_html_text_size_property_maxlength.reuse(_jspx_th_html_text_0);
168 return false;
169}
So I am willing to suppose that out.write() isn't throwing the
exception, which leaves only _jspx_meth_html_text_0(pageContext).
Looking into that method, I see 3 candidtates:
_jspx_tagPool_html_text_size_property_maxlength.get(org.apache.struts.taglib.html.TextTag.class);
_jspx_th_html_text_0.doStartTag();
_jspx_th_html_text_0.doEndTag()
_jspx_tagPool_html_text_size_property_maxlength.reuse(_jspx_th_html_text_0);
The question is why does one of these throw a Servlet exception when
form doesnt? Though the form tag hasn't closed yet so it could still be
the form tag, when I misname the taglibrary in the JSP I get a different
error.

RE: Form data vs request attributes
I don't appear to have to declare customers in the form, but if I don't declare suburb, I get an error... what is the difference? 'suburb' is a form property, Struts will call get/setSuburb as it populates the Form Bean and generates the HTML. 'customers' is a collection of things to be used to populate a select list. It may or may not be a property of this particular form. It can live anywhere-- request scope, application scope, session scope. I don't consider the contents of a select list to be a property of the form, so I don't put it in the form bean. The way you're doing it is fine. If 'customers' never changes, consider using Application scope (a Context attribute). If it varies by user, session scope might work for you. That way you don't have to put it in request scope repeatedly. -- Wendy Smoak Applications Systems Analyst, Sr. Arizona State University, PA, IRM - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: initializing properties for Actions
Frank,
I think you are on to something here. Why don't you subclass ActionMapping
and in your subclass put your member variable and getter and setter. You can
then access the value from your action class's excecute method's mapping
parameter after you cast it to your ActionMapping subclass?

Carl,
That didn't work, but thanks anyway. I also tried changing the data type for
passwordDisabled to a String and have the normal get/set methods but that
didn't
seem to change the outcome either.
I think the real problem is that it is trying to call setPasswordDisabled on
org.apache.struts.action.ActionMapping instead of my LoginAction class. Not
sure
if this is a known you can't do that or a known bug or whatever (I'm using
struts 1.1.0). I was unable to find any info on this topic either in the
archives or on jakarta.apache.org.

Re: Form data vs request attributes
ActionForm objects are representation of a form and the data in the form. It holds the values of your INPUT, SELECT, TEXTAREA and other form controls. The options of a SELECT control are only used to help the user choose a value; its only purpose is to give the SELECT control a value and isn't itself a value of the form. Think of it this way: the form doesn't lose any data by changing your SELECT into an INPUT type=text. Confused? Think of it another way: The OPTION values don't get submitted, only the value of the SELECT. So: 1) The ActionForm helps you get to the values submitted with the form, and so suburb is required there because it's part of the form. 2) The ActionForm doesn't hold OPTION values, only the value of the SELECT. 3) You need a way to tell html:options what to show, and you can do it by specifying a collection that's in scope (doesn't have to be the request scope).

bean:message MessageFormat and number formating
Hi,
I've recently switch to a resource.properties file to externalize all
text from jsp (in the perspective of translation of the site)
The site is a classic e-commerce web site, so I dsiplay a Cart and the
amount of the products in the custumer's cart.
In my old jsp I wrote :
fmt:formatNumber value=${total} type=CURRENCY/
in order to format the price in a sentence like Total amount $ 150.
Now I'm writting
cart.amount=Total amount {0}.
in the resource.properties.
And in the JSP :
bean-el:message key=cart.amount arg0=${user.amount}/
finally I loose the price formatting porvided by the fmt:formatNumber
tag.
Is there a way to use a MessageFormat and have the parameters formatted
like fmt:formatNumber do ?
Thanks for all suggestions,
Carl

RE: initializing properties for Actions
From: Frank Maritato [mailto:[EMAIL PROTECTED] I think the real problem is that it is trying to call setPasswordDisabled on org.apache.struts.action.ActionMapping instead of my LoginAction class. I remember being confused about this, too. When struts-config.xml gets run through the Digester, an action tag causes the creation of an ActionMapping object. So any properties you specify in action are part of an ActionMapping object. An ActionMapping has a 'type' property that is the class name of the Action that will be created. (Type actually comes from ActionConfig.) Later, some other part of Struts will call getType() on the ActionMapping object and will instantiate your Action class. How do you create your own ActionMappings? I know I read it somewhere... It's covered in chapter 7 of Struts in Action but I can't find more than this in the Struts docs: http://jakarta.apache.org/struts/userGuide/building_controller.html I generally just use context-param (in web.xml) and context.getInitParameter(). -- Wendy Smoak Applications Systems Analyst, Sr. Arizona State University, PA, IRM - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

JSTL DynaValidatorForm
Hi,
For x and y reasons I've to create my own version of the c:out tag.
Everything is working great for everything BUT DynaValidatorForm where I get Unable to
find a value for value in object of class
org.apache.struts.validator.DynaValidatorForm using operator .
I'm using the evaluate method part of
org.apache.taglibs.standard.lang.support.ExpressionEvaluatorManager to obtain the EL
values.
I tried the jars part of the Jakarta TagLib, and the ones provided within the Struts
EL. Both with the same result.
I bet it's a stupid thing I overlooked.
Now here is the funny part: the c:out tag, which is supposedly using the same code,
doesn't seem to have the same issue...
Here is the exception stack:
javax.servlet.jsp.JspException: An error occurred while evaluating custom action
attribute value with value ${manageForm.value}: Unable to find a value for value

This is the call crashing:
value = ExpressionEvaluatorManager.evaluate(value, value_, Object.class, this,

Thanks the help,

RE: Form data vs request attributes
The reason I don't do this is because if the form is in session scope, it hangs around consuming memory until the session goes away. As a caching mechanism, this bites rocks, because it is cached for each user. :-/ By putting this type of stuff in request scope instead of on the form, it becomes transient regardless of where the form resides. But if you use a DAO layer with caching (like iBATIS), one copy of this stuff can be cached (globally) so you are not hitting the database all the time.

Re: Including multiple servlets from a jsp page.[Now: Tiles Help]
Thank you very much! That was exactly what I needed. Now I just need a little advice on working with Tiles. Do I need to have a tiles definition for every single different view? I will give a small example. definition name=page.default path=/templates/index.jsp put name=head value=/common/head.jsp / put name=centersection value=center.section / put name=bottomtable value=/common/bottomtable.jsp / /definition definition name=center.section path=/templates/centersection.jsp put name=leftbar value=left.bar / put name=mainsection value=/common/mainsection.jsp / /definition definition name=left.bar path=/templates/leftbar.jsp put name=first value=/common/navigation.jsp / put name=second value=list.events / /definition This will give me the look for my front page. But lets say once you log in, you have a different 'left.bar'. So I would have to add: definition name=login.page.default extends=stinkytoe.default put name=centersection value=login.center.section / /definition definition name=login.center.section extends=center.section put name=leftbar value=login.left.bar / /definition definition name=login.left.bar extends=left.bar put name=second value=/common/userinfo.jsp / /definition That seems like a ton of work for each new view. If my 'mainsection' is my content area, that means I need to add 2 definitions for each new content page? Is there a way to dynamically insert a page as the 'mainsection' Am I missing something here?

RE: initializing properties for Actions
Frank,
I tried subclassing ActionMapping and setting the type attribute in the
struts config action-mappings tag.
The runtime error goes away but the setter method never gets called. It
could be a bug.

Frank,
I think you are on to something here. Why don't you subclass ActionMapping
and in your subclass put your member variable and getter and setter. You can
then access the value from your action class's excecute method's mapping
parameter after you cast it to your ActionMapping subclass?

Carl,
That didn't work, but thanks anyway. I also tried changing the data type for
passwordDisabled to a String and have the normal get/set methods but that
didn't
seem to change the outcome either.
I think the real problem is that it is trying to call setPasswordDisabled on
org.apache.struts.action.ActionMapping instead of my LoginAction class. Not
sure
if this is a known you can't do that or a known bug or whatever (I'm using
struts 1.1.0). I was unable to find any info on this topic either in the
archives or on jakarta.apache.org.

I'm not sure that this will solve your pb, but I think you should use

Re: Form data vs request attributes
In article [EMAIL PROTECTED], [EMAIL PROTECTED] says... The options of a SELECT control are only used to help the user choose a value; its only purpose is to give the SELECT control a value and isn't itself a value of the form. Think of it this way: the form doesn't lose any data by changing your SELECT into an INPUT type=text. Confused? Think of it another way: The OPTION values don't get submitted, only the value of the SELECT. Ahh, that make sense. Thanks. A followup question if I can... The ActionMapping that my XXXAction returns forwards to the same XXX.jsp that was used as the original input for XXXAction. I have noticed that, in XXXAction, if I change the value of one of the ActionForm variables, the JSP will plug the new value into the INPUT when it serves it back to the user. That's sort of neat, but it makes me wonder what will happen if an ActionMapping from another unrelated Action forwards to XXX.jsp. The other action may well have setup the customers variable in the context, but it is unlikely that it will have the same form as XXXAction. What happens in this case? Thanks again. -- Craig Edwards Sydney, Australia - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

OO Struts
I am designing my first struts application, but I have been a java developer for about 5 years. I am actually refactoring a survey app. I wrote. The way struts was explained to me was my ActionForms were like my Transfer objects and my actions were just that, the action that was requested... storing in the database. With that said, how would I handle building a survey object (surveyForm) that had N number of question objects which in turn had N number of answer objects? I am really confused. Thanks for any insight. travis - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
anyone using jstl side by side with the strut taglibs?
Hi, I'm nearing the end of a prototype for my first Struts application. At first, I used JSTL to handle most of my iteration, declarations, and conditional operations. Then, as I learnt more about the Struts taglibs, I decided to simply use the Struts libraries, for the sake of consistency with the framework. Does anyone regularly combine JSTL and Struts taglib usage? I'm curious as to whether or not it's an effective approach; I think it could perhaps lead to confusion when developers first begin working on an application using both libraries.

what is the right way to test whether execute() is called after validate()?
I'm sorry if this is too basic, I'm still really green.
I'm validating a form. This form is used for adding and editing widgets. I
use the same actionHandler, where I test a request parameter and set up the
form accordingly. It builds my form object and either resets it for an add,
or retrieves a widget from the DB and sticks it in my object.
What I found was, when my validation failed on add or edit, it was still
going thru the execute() method of my actionHandler and was therefore
reset()ing on add or re-building my form object on edit.
So, I put in something like this instead:
if ((request.getParameter(Submit) == null) ||
(!request.getParameter(Submit).equals(Submit))) {
if (request.getParameter(addEdit).equals(edit)) {
form = buildCompanyForm(request.getParameter(id), request);
} else {
form = new CompanyForm();
form.reset(mapping, request);
}
}
And it works, but testing whether Submit has been pressed seems kinda nasty.
I'd like to learn a better way.
Thanks in advance,
Janice
