RE: Struts Validator / dynamically enabling/disabling
I tend to use the DispatchAction mechanism for forms that are used to do
create/update/delete of objects. The pattern I have fallen into is having
cancel be another one of the dispatch methods in this case. I have
validation turned on for the form, but, conditionally disable the validation
both on the client-side and on the server-side based upon the setting of the
dispatch method.
It is actually quite easy to do for the client-side implementation. You
already have to explicitly provide the onSubmit event handler for the form
anyway. No one is forcing you to call the JavaScript function generated by
the html:javascript/ tag. So, I have my own JavaScript function that
conditionally calls the validateYourFormNameHere() function based on the
setting of the dispatch method. An example of mine looks like this:
function handleFormValidation(form) {
result = true;
if (form.dispatchMethod.value == save) {
result = validateModifyUserForm(form);
}
return result;
}
On the server-side, this does require a form class where you can put the
conditional logic in your validate() form function override. However, this
doesn't prevent me from using DynaForms for the tedious getters and setters.
It just means I have to extend the flavor of DynaForm I am using depending
on whether action-based or form-based validation is being used. In the form
class, you only override the validate function and conditionally call the
super.validate() based upon the setting of the dispatch method in the form.
You can still define all the form properties in your Struts configuration
file.
I'm not thrilled with this approach, but, it does work within the current
architecture to make the validation somewhat dynamic without being overly
complex. Your mileage may vary. :-)

P.S. Having the cancel method in the same DispatchAction subclass that
handles creates/updates/deletes has worked nicely for workflows that are
multiple steps too. I tend to use session scope beans in that case both for
the form and for related workflow data. So, I can have common logic for
releasing session scope resources for the workflow in one common action for
create/update/delete/cancel.

Subject: Struts Validator / dynamically enabling/disabling
Hi.
I am using the Struts Validator in conjunction with a
ValidatorForm. My html
form has two submit buttons, one for saving without
validation, another one
with validation.
Is it possible to dynamically switch on and of the validator
depending on
which button is pressed?
I could of course dynamically set the action attribute of the
form tag,
using JavaScript. But I don't want to depend on JavaScript
being switched
on/off in the clients browser.
Another possibility, that didn't convince me up intil now, is
writing a
custom validate method, that checks for the value of the
clicked button.
This method could be called before every other validate
method and return
false in the case no validation is necessary and an empty ActionErrors
Object to make the framework assume everything is OK. Would this work?
Any suggestions?

Unless I'm missing something here, you simply use: request.getParameter(fieldid); in scriptlet code in any of your leaf JSPs to access this request parameter.

RE: Tiles and parameters...
Craig, Yes, I am relatively new to Tiles. This is my first major project using it and we make extensive use of Tiles in our webapp. We also use the display taglib and take advantage of its column sorting support. Sorting of table data is handled automatically by this taglib using request parameters and it works fine in our webapp. For example, the default display of our user list is sorted in ascending order based on the values in the 4th column (zero based sort offset in example below) of the listing like so: /portal/admin/users/list.dbm?order=ascsort=3 This will trigger the following action mapping in our struts-config.xml file: actionpath=/portal/admin/users/list type=com.verisign.dbms.portal.ListUsersAction forward name=success path=portal.admin.users.list/ /action And the following tile definitions are interpreted when the success forward is used: definition name=portal.admin.users.list extends=portal.admin.users put name=menu value=portal.menu.admin.users.modify / put name=body value=portal.body.admin.users.list / /definition definition name=portal.body.admin.users.list extends=portal.body.admin.users put name=bodyContent value=/portal/admin/users/list.jsp / /definition And the list.jsp usings the display taglib tags: display:table width=90% name=%=UserMgmtBean.KEY% property=users scope=session requestURI='%=request.getContextPath() + /portal/admin/users/list.dbm%' ... /display:table In the layout JSP that ultimately includes the bodyContent value above, we are using: tiles:insert attribute=bodyContent/ which is comparable to the example that you suggest I try. So, I can honestly say that I have tried it and it works. :-) Without rummaging through the display taglib source, the traversal through action mapping to action with forward to the tile definition that ultimately displays our master page layout containing the leaf listing JSP is working to control sorting. So, the request parameters are getting through to the leaf listing JSP. Otherwise, the display tags wouldn't be responding to the request parameter settings that control how to sort the list contents. We are working with the version of Tiles integrated in Struts 1.1-b2. Maybe you are working with a different version of Struts/Tiles. If so, that might explain why something similar isn't working for you.

Validation DTD bug?
Before submitting a bug report on this, I wanted to verify that I am doing
this correctly. This isn't causing any real runtime problems at this point.
I just discovered the problem when I turned on DTD validation in my IDE. I
am working with the 1.1-b2 release, but, I checked and the same problem
exists in the 20021206 nightly build. The validation_1_1.dtd file has the
following element definition for field elements:
!ELEMENT field (msg?, arg0?, arg1?, arg2?, arg3?, var* )
Shouldn't this be:
!ELEMENT field (msg*, arg0*, arg1*, arg2*, arg3*, var* )
Unless I am missing something, the DTD should allow for multiple definitions
of each subelement in a field element definition. As an example of why
this is so, I have a validation definition for a field that has both minimum
and maximum length validations specified. The error messages for both of
these validations want to insert the number for the minimum or maximum
length as the arg1 value. So, I need more than one arg1 definition
inside the 'field definition. The example from my working application is:
field property=zip depends=required,minlength,maxlength,mask
msg name=mask key=msg.zip.invalid/
arg0 key=prompt.zip/
arg1 name=minlength key=${var:minlength} resource=false/
arg1 name=maxlength key=${var:maxlength} resource=false/
var
var-nameminlength/var-name
var-value5/var-value
/var
var
var-namemaxlength/var-name
var-value10/var-value
/var
var
var-namemask/var-name
var-value${zipLong}/var-value
/var
/field
This example from my code only requires multiple arg1 definitions, but,
the same principle applies to the other arg fields. Similarly, I could
contrive an example that would require multiple definitions for msg. The
convention in the examples provided with the release always reserve arg0
for the display name of the field. So, I suppose you could make an argument
for not needing support for multiple arg0 elements. Still, the DTD
probably shouldn't rely on that convention.

RE: [OT] Learning Curve Management or Confusions of a Newbie
I think the Java Tutorial trail approach would be a good fit for this: http://java.sun.com/docs/books/tutorial/reallybigindex.html For example, there already is a Creating a GUI with JFC/Swing trail: http://java.sun.com/docs/books/tutorial/uiswing/index.html Similar to this in concept, there could be a Building a webapp with Struts trail. Granted, this may not belong in the reallybigindex maintained by Sun because Struts is under the Apache umbrella. However, it might be time to setup a reallybigindex for an online Apache Tutorial comprised of trails similar to the way trails are used in Sun's online Java Tutorial. Specifically with respect to learning Struts though, there is already a significant amount of online learning material to be found directly or indirectly from here: http://jakarta.apache.org/struts/learning.html Still, I do see the value in having trails that organize some of the online information in various trails to follow through this wealth of information.

I've been a C/C++ programmer for 20 years, but after dinking around for a few months with ASP, VBScript, PHP and a few other technologies, I decided that Java was the language to build my web apps in. A month ago I was completely cold. Didn't know the first thing about any of this stuff. But I knew I wanted to learn it, so off I went, marching into the high weeds. First I had to learn Java. Then came servlets and JSPs and Tomcat. And along that path I also had to absorb Ant. And JUnit. And Log4J. And then there was a bunch of time lost exploring NetBeans/Eclipse/WebSphere before settling on JEdit as my environment of choice. Then came Struts, and all the various taglibs. An experiment with Cayenne. And Cactus. And god-knows what else I've explored. And through it all, I am continually amazed at the strength and breadth of the resources and support available. And equally frustrated by it. I can never remember where I saw a particular bit of information. So when I finally learn enough to understand what Ted was talking about in his monograph on Connection Pooling, I can't remember where I saw it. And when I want to learn enough about EJBs to figure out if I need to care about them, or if they are relevant to my planned project, I have to wade through another day of voluminous coverage before I have enough of a handle on what they are to make some intelligent guesses about where to look next. My point is that I believe the Apache/Java/Struts/... universe is quickly reaching a point where its very breadth is becoming a barrier to entry for people who don't have a couple of months to devote to bootstrapping themselves. Is there any thought being given to creating a higher-level resource interface that could serve as a single point of reference for all things Apache? (I realize that all things java would be going way too far.) As a simple solution, if every document in the Apache infrastructure had a meta tag that listed the questions answered by the document, then a very powerful, automated FAQ could be maintained. And such a system would make it much easier (I believe) to find things quickly than simply searching the site for key words. This may not be the best (or only) solution, but I do believe that for all the very specific support and discussions there are, there is really very little over-view material to assist

RE: validator plugin
Michael,
I ran into this problem myself and the online review chapters of Chuck
Cavaness' Struts book provided the answer. According to the chapter on the
Struts Validator,
There was some confusion in one of the earlier beta releases for the
Validator that used multiple set-property elements. That is no long
supported and you should use a single set-property element that specifies
multiple Validator resource files, separated by a comma. Also notice that
the property value is the plural *pathnames*.
Your example code indicates you are using the deprecated form with separate
set-property elements. Try this instead:
plug-in className=org.apache.struts.validator.ValidatorPlugIn
set-property property=pathnames
value=/WEB-INF/conf/validator-rules.xml,/WEB-INF/conf/validation.xml/
/plug-in
Assuming you are working with the latest beta release or a recent nightly
build, this should help.
Good luck,

Hi,
I´m having problems using the validator plugin. When leaving fields blank,
I expect struts to take me back to the registration form. I copied most of
the code from an example and read the chapter concening this topic in the

For some reason though it appears that nothing is happening! Well, I added
my own version of the validation mehod in my form bean just to see if it
goes in there at all and it does. However the ActionErrors is always empty.

System.out.println(VALIDATING!! + errors.size()); // this always
returns 0

==
I´ve rechecked the files about 10 times and I just don´t seems to be able to
get it to work.
Another question I have is, when validation is false, do I get redirected
back to the form automatically or do I have to specify this in the Action
class using:
return mapping.findForward(registrationForm); ?
Any help on this matter would be greatly appreciated,
Thanks,

RE: Why html:javascript failed?
I had this same symptom when trying to use client-side validation with deprecated form of plug-in specification for the Validator plug-in. If you are using separate property elements to specify multiple xml files for your validator plugin, you need to use a single set-property with plural property name of "pathnames" and the multiple files comma separated in the value field. In my installation, the correct configuration looks like this: plug-in className="org.apache.struts.validator.ValidatorPlugIn" set-property property="pathnames"value="/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml"/ /plug-in Just because you are having similar symptoms, it doesn't necessarily mean it is being caused by the same problem.

Hi,
In our application we use a similar concept :
- we have a class like this :
public abstract class BaseAction extends Action
What about DispatchAction and LookupDispatchAction? Anyone have a good
solution for reuse of common action logic across these multiple action base
classes provided by Struts?
In this class :
- we added some usefull field like a logger an a pointer to a
singleton that
retains application's data
protected Log log = LogFactory.getLog(this.getClass());
protected static final Infos infos = Infos.getInstance();
- We change the modifier of the execute Method so as to be
sure nobody use
it directly:
public final ActionForward execute(ActionMapping
_mapping, ActionForm
_form, HttpServletRequest _req, HttpServletResponse _res)
throws Exception {
- In this method we check the user session and log in information
- At the end of this method we call
return executeAction(_mapping, _form, _req, _res);
- This method executeAction is defined as this :
public abstract ActionForward executeAction(ActionMapping
_mapping,
ActionForm _form, HttpServletRequest _req,
HttpServletResponse _res) throws
Exception;
- So when we create a new action, we extend BaseAction and
implement the
abstract method executeAction
This way, we have automatic user login check, and a logger at
disposition.

Subject: Right way to extends Action
I want all my Actions to extend BaseAction.
In BaseAction I want to check user session and to put some
data in it, if
that data doesn't exist.
Is it good way:
public class SomeAction extends BaseAction {
public ActionForward execute( ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response ) {
super.execute( mapping,form, request, response);
OK, proceed ...
public class BaseAction extends BaseAction {
public ActionForward execute( ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response ) {
if (userSession is wrong) {
-try -- put data in session
-catch -- return mapping.findForward(wrongSession);}
else return null; //everything is OK
What you think about this way and is there better way to
extend Action?
Thanks.

Since we have the source of these helper actions, I think it is cleaner to have common action logic in one base action class of my own and then extend all my application actions from this one base action class. I'm good at cut/paste. So, it is easy to create my own versions from Struts sources for the helper classes that extend from my own base action class. :-) Still, that means I need to track changes made in these helper actions as Struts improves over time. I would hate to miss out on any refinements/improvements made over subsequent releases.

RE: PHP version of Struts

RE: PHP version of Struts
Wow! A lot of discussion about this in less than 24 hours. I'm still catching up and haven't read all the messages yet. So, I apologize if someone else already addressed what I am about to say. First of all, I am neither for or against this initiative personally. I have not done any PHP development myself and probably never will. Still, I thought this would be interesting to the person asking the original question about PHP and Struts. Secondly, the initial thrust for a reference implementation is around PHP because of the wide adoption of PHP as a web page scripting language. However, my best understanding of the brief announcements I have seen at JavaOne suggest the real focus is opening up web page development to any reasonable web page scripting language out there with PHP as the initial proof of concept. Personally, I wouldn't get hung up on whether PHP is a good fit with Struts or not. The real take home message is they are taking a serious look at better support for the commonly used scripting languages out there today for web page development. - Van Mike Van Riper mailto:[EMAIL PROTECTED] -Original Message- From: Van Riper, Mike Sent: Wednesday, June 11, 2003 4:05 PM To: Struts Users Mailing List Subject: RE: PHP version of Struts At JavaOne this week one of the announcements about future plans was for scripting language support, specifically in the context of web pages, that will focus initially on PHP support.

July 2nd meeting at 7pm in Mountain View
We had a nice turnout for the Struts User gathering in San Francisco last week. It was good to see several of our group members in attendance. Our next meeting is scheduled to take place in Mountain View at 7pm on Wednesday, July 2nd. A demonstration of Exadel Struts Studio, by Igor Shabalov, will show why you need more than just a Java IDE to be a productive Struts User. Please refer to the online announcement for the details and directions to the meeting site: http://www.baychi.org/calendar/20030702/ It is important that I get an accurate headcount in advance for meeting facility planning purposes and for determining how much pizza and soft drinks to order. So, please do RSVP in advance per the instructions in the online announcement. I'll make sure that the facilities and food are adequate for all that RSVP by noon on the day of the event.

RE: FW: Validation DTD bug? (impacts my use of Struts Console)
James,
I never received any feedback, but, they did address this problem in the
just announced release of the 1.0.1 version of the Commons Validator. The
DTD in this version has the following DOCTYPE specification:
!DOCTYPE form-validation PUBLIC
-//Apache Software Foundation//DTD Commons Validator Rules
Configuration 1.0//EN
http://jakarta.apache.org/commons/dtds/validator_1_0.dtd;
And the ELEMENT definition in the DTD for field elements has been changed to
this:
!ELEMENT field (msg|arg0|arg1|arg2|arg3|var)*
Until a future release of your tool that supports this new version of the
Commons Validator, I can continue to hand edit my validation.xml files
directly. My main concern was that the DTD allow for the necessary field
validation definitions going forward and this has been dealt with. So, I'm a
happy camper now. It would have been nice for someone to let me know they
were taking care of it when I asked though. Oh well.
Cheers,
Mike Van Riper

I'm guessing your Validator config file issue is
similar.
I don't think it is. The DOCTYPE in that case was
already using the 1.1
versioning like so:
!DOCTYPE form-validation PUBLIC
-//Apache Software Foundation//DTD
Validation Configuration 1.1//EN
http://jakarta.apache.org/struts/dtds/validation_1_1.dtd;
I believe this has more to do with the original
issue I posted on the
struts-user list. My validation.xml file doesn't
validate successfully
against this DTD requirement:
!ELEMENT field (msg?, arg0?, arg1?, arg2?,
arg3?, var* )
because when you use both the minlength and
maxlength validations on a
single field, you end up with more than one arg1
element inside the field
element definition like so:
field property=zip
depends=minlength,maxlength
arg0 key=prompt.zip/
arg1 name=minlength
key=${var:minlength} resource=false/
arg1 name=maxlength
key=${var:maxlength} resource=false/
var
var-nameminlength/var-name
var-value5/var-value
/var
var
var-namemaxlength/var-name
var-value10/var-value
/var
/field
Unless the arg1 is defined separately for
minlength and maxlength
validations, it is not possible to generate the
correct validation error
message with the appropriate minlength or maxlength
value inserted in the
error message. This is why I suggested that the DTD
needed to change like
so:
!ELEMENT field (msg?, arg0*, arg1*, arg2*,
arg3*, var* )
This way, you are allowed to specify different
argx values for
substitution in the error message when different
validation rules are
violated. I realize this is a validation DTD issue
and not a Struts Console
issue. However, it is preventing me from using the
Struts Console in the
recommended fashion with validation turned on and I
do believe this is a
validator DTD bug.
I've already changed my local copy of the DTD so I
can validate against it
in my IDE, IntelliJ. However, this doesn't help me
when I try to use the
Struts Console on my validation.xml file. I'm
surprised that I didn't get a
single response when I posted this on the
struts-user list before. Should I
have posted this on the struts-dev list instead?

RE: Placing a Scriptlet inside bean:message
I believe support for this depends upon whether the custom tag is configured in the tag library descriptor file to support runtime expressions for the attribute in question. I just looked at the struts-bean.tld for B2 and the key attribute of the message tag has the rtexprvalue set to true. So, it should support this sort of thing. I believe the docs for the various Struts custom tags also state whether runtime expressions are supported for particular tag attributes. However, the tag library descriptor information is used by the JSP engine. So, you can definitely count on that information whether the docs say it is so or not.

RE: iterate question
I have a similar need to the one expressed by Kirby. I have not used the nested extension, but, I have read through the online primer. I saw nothing there that would indicate it would handle *dynamic* tree structures. Yes, you can use the nesting custom tags to any depth you want. Yes, you don't need to know in advance how many items there are in a collection at a particular level. However, it looks like you need to know in advance what depth to go to. When the tree is being generated dynamically and the depth can not be known in advance, I don't see how to use the nesting extension to handle it. I hope that I am wrong about that because I'd love to just use the nesting extension rather than write something on my own. If the nesting extension can handle this situation, please point me to the right part of the docs or an existing example that will help me figure that out. Assuming I am right and the nesting extension doesn't handle what I need yet, my sense is there might be a way to enhance the nesting extension to handle this for recursive structures. For example, consider a Node object that had some instance data and a collection of child Node objects and a getChildNodes() method. What if nested:iterate took an additional parameter which was recurseProperty=childNodes? It should be possible to implement tail recursion in the implementation of nested:iterate that would repeat the execution of the body of the nested:iterate tag with the new collection being the one returned from the getChildNodes() call on the current node. This would do a depth first recursion of nodes outputting the same information for each node. Assuming there is a way to get depth information, I could use that information in the body of my nested:iterate and dynamically reflect that in the formatting of the nodes for display too. Of course, it is not that simple. There would be intermediate state to maintain and correctly return to and continue on from for each time a recursion to another level happened. The nesting extension does quite a bit already and this may not be the best way to solve my recursive structure handling problem. Then again, maybe it would make sense.

RE: iterate question
Of course, I immediately found an example for handling dynamic nesting as soon as I posted that I hadn't. Figures. There are some example projects that use the nested custom tags in the resource section of the Jakarta Struts site. One of them uses a relatively simple trick (once you have seen it, it seems simple :-)) with dynamic inclusion of a JSP to handle node data.

You must specify a key attribute in all but your default message-resources elements. In order to pull messages from non-default properties files, you have to specify this key attribute of the message-resources element as the bundle attribute of the bean:message tags you are using in your JSP pages. If you have this in your struts-config file: message-resources parameter=MyResources key=MY_RESOURCES_KEY/ You would insert messages from the specified properties file like this: bean:message bundle=MY_RESOURCES_KEY key=prompt.contact.name/ At least, this is how I am doing it and it is working for me.

Actually, it is called in BaseFieldTag.java for the text tags which extend from it and additionally in a few other tags that don't extend from it (e.g., TextareaTag.java). So, it doesn't matter so much whether the request parameters are filtered/converted when populating form beans because on the way back out to populate the form field values in the JSPs it will happen automatically as long as I am using the Struts html custom tags.

RE: set a value from a form to a form
One way is to use the html:hidden tag in addition to whatever you are doing to display the uneditable form data. It works like all the other form tags. So, all you have to do is set the property attribute to match the name of the uneditable form property and it should work. This is the Struts custom tag equivalent for specifying input type=hidden ... directly in HTML. If you do decide to use an HTML form element to display the uneditable value and set the disabled attribute on it, you will want to also include a html:hidden element for the same property. From my own experimenting on this, I found that the value for my disabled text input fields were not being submitted with the form. Adding the hidden form element for the same property does preserve any incoming form data when the form is submitted. - Van -Original Message- From: Michael Lee [mailto:[EMAIL PROTECTED]] Sent: Tuesday, September 10, 2002 4:14 PM To: Struts Users Mailing List Subject: set a value from a form to a form I have a form object that populates html fields.

International Struts Meetup Day
When I was looking into starting a Silicon Valley Struts User Group back in March, I put in a proposal to meetup.com for a new topic area for Struts. Meetups happen at local cafes (and other places) in 586 cities across 43 countries. When I didn't hear back from them after a few weeks, I went ahead on my own to get the Silicon Valley group up and running. Well, it turns out that they did accept my proposal and were just slow in getting around to it. I no longer need what they provide now that the Silicon Valley Struts User Group is up and running. However, I thought that people in other areas that do not yet have a local user group to participate in might find this interesting. The Meetup folks have established the 3rd Thursday of every month as an International Struts Meetup Day. You can register your interest in participating with other Struts Users from your local area and participate in an online vote for the local bar or restaurant where you will meet. See http://struts.meetup.com/ for details!

RE: Button labels and DispatchActions mix?
Actually, I think the least amount of work (assuming you don't object to adding a small amount of trivial JavaScript logic to the JSP page) is to change your html:submit to an html:button and then add an onclick JavaScript event handler that sets a hidden form field with the desired submit action value before submitting the form. You can even embed the event handler logic directly in the HTML button definitions like so: html:hidden property=action value= / html:button property=dontCare1 onclick=this.form.action.value='reset1';this.form.submit(); bean:message key=search.button.reset / /html:button html:button property=dontCare2 onclick=this.form.action.value='reset2';this.form.submit(); bean:message key=search.button.reset / /html:button This should work even with two separate forms being used in the same JSP for the two identically named buttons. Of course, you would then need two instances of the html:hidden tag to include the action property in the two separate HTML forms. Note: I haven't tested this exact code snippet above. So, there could be some minor typo in it. However, I have used this technique successfully in the past.

RE: Struts Validator-nextreleasewhen (was validwhen)
With great trepidation, I must inquire as to the likelihood of a next release of the commons-validator in the near term future. (ducking for cover now as the flames telling me to read the Apache release process policy on the web site are fired off in my direction ;-)). Seriously, I did look in the bug database already. If my search was setup correctly, I only saw 5 open bugs against Validator (amazingly low number given that it is supposed to be crap) and they were all categorized as enhancement requests. I suspect that not too much has changed since the version that shipped with Struts 1.1. So, you may not want to push out a new release at this time. However, it is unfortunate that the ability to modularize development of larger apps with multiple struts-config files and multiple application resource files is pretty much there in the Struts 1.1 release except for mutliple resource files support in Validator. Since it looks like the support for bundle attributes was added at least at the arg level, a dot release now of just the commons-validator would make it possible to use multiple resource files to some degree with the Validator in a Struts 1.1 webapp. I'm not looking for a fixed date commitment. I realize it is all volunteer efforts on this stuff that can't be held to any particular schedule. I'll totally understand if there are no plans to move towards a dot release of Validator anytime soon, but, I am curious as to whether plans to move towards a dot release are imminent or not even on the horizon. -Van Mike Van Riper mailto:[EMAIL PROTECTED] http://www.baychi.org/bof/struts -Original Message- From: Steve Raeburn [mailto:[EMAIL PROTECTED] Sent: Thursday, August 14, 2003 8:41 AM To: Struts Users Mailing List Subject: RE: Struts Validator-validwhen It's not in Struts 1.1 but it's available in the nightly build and will be in the next release.

RE: using modules versus simply using multiple struts-config files
-Original Message- From: Bailey, Shane C. [mailto:[EMAIL PROTECTED] Sent: Wednesday, August 13, 2003 3:01 PM To: 'Struts Users Mailing List' Subject: RE: using modules versus simply using multiple struts-config files I think if you are going to use messages like that then one place you may run into problems is with the Validator. I can't remember if not all or none of the elements in the Validator (which had the key attribute) didn't have a bundle attribute (so I don't know how it would determine which bundle to look up and I can't imagine it goes through every one automatically). At least I ran into a problem when I first started using Validator and attempting something similar. If you are not using Validator (or it works differently now or I just was not using it right) then disregard, of course. I do plan to use Validator and you are right. I just checked and the commons version of validator that shipped with Struts 1.1 doesn't allow for the bundle attribute. Coincidentally, it appears that the DTD (and I assume the related source code too) in the commons validator project were updated within the last week to add the bundle attribute. So, I could probably pick this change up in a recent nightly build of the commons-validator.jar. Unfortunately, I can't use nightly builds of anything in my project. It was hard enough for me to get approval to use the 1.1-b2 release of Struts for a project last year. It worked out great by the way. WebApp has performed flawlessly in production since December of last year. I'm not even going to try to get approval to use an open source nightly build. :-( Which leads me to my next question. Are there plans for an official release of an updated commons validator module that could be used with Struts 1.1 where I'd be able to use the bundle attribute any time soon? I'm not expecting an answer to that question on this list. I think there is a separate commons-user list or some such thing like that where I will have to direct that question. In the meantime, I'll have to put all my field name prompts and any validation messages in the default resource file. This was exactly the kind of info I was looking for.

I think this is where one of the differences in my approach comes in.

using modules versus simply using multiple struts-config files
I did search the archives and there is information about using multiple config files and separately about using full-blown modules too. There may have been a comparison of the two approaches somewhere in the archives too, but, I was not able to find it. Thus, my reason for posting this to the group. I'm setting up the webapp infrastructure for a new project. This is the first opportunity I have to use the new module support in Struts 1.1. As I am investigating it, it seems like the new capability to specify multiple struts-config files in your default module configuration in the web.xml file gets you most of the modularity advantages that multiple modules provide. Sure, you do get to leave the module leading subdirectory out of your action mapping definitions when you define separate modules in web.xml for each struts-config file. Other than that, I'm not seeing the advantages of using full-blown modules when I could just setup separate struts-config files for each logical module. On the flip side, you have to deal with properly switching between modules when you use modules. Also, every request must go through an action mapping to use modules. Right now, I'm leaning towards setting up separate struts-config files for each logical module and simply specifying them as a comma separated list in the default module configuration in my web.xml. This is a relatively small webapp which can be logically partitioned in to about 5 areas. Also, there will be three of us working in parallel on a tight schedule. So, it seems to me that I get the modularity benefits without the module restrictions by simply setting up separate struts-config files. Before going too far down this path, I was interested in any feedback from others on the list about this approach.

Since there will be a direct one-to-one mapping between each subsection of the webapp and the resource file specific to that subsection, I think this will be something that will be easy to remember. For example, a logical report module would specify the report bundle in bean:message tag instances that used the report module resource file like so: bean:message key=report.header bundle=report / I am inferring this from the main Struts 1.1 example application where an alternate resource file is accessed like so in logon.jsp: bean:message key=prompt.password bundle=alternate / I think you should be able to do the inverse of this when using separate module configurations. For your module related property lookups, you could use the default resource file configured for that module. For the common ones that you wanted to use across all modules, you would have a configuration entry for the default resource file in each module struts-config file and make that your alternate resource file for the module. So, for you it would be the property lookup of a shared resource that would need to supply the bundle attribute to the bean:message tag. Assuming you used common as the key for your shared properties, your lookups in the common resource file would be the ones that needed to supply the bundle attribute: bean:message key=app.copyright bundle=common / This isn't as transparent as a patch to Struts that supports inheriting common properties into the default resource file for each module, but, it would allow reuse of common properties across multiple modules. At least, this is my understanding of how it could work. I haven't tried modules yet. So, I can't be certain of that. Sadly, since I am using modules, I can't think of any advantages of modules if you can have multiple struts config, tiles def and resource files and no modules. -Original Message- From: Van Riper, Mike [mailto:[EMAIL PROTECTED] Sent: Wednesday, August 13, 2003 2:02 PM To: List Struts-User (E-mail) Subject: RE: using modules versus simply using multiple struts-config files -Original Message- From: Van Riper, Mike Sent: Tuesday, August 12, 2003 5:55 PM To: List Struts-User (E-mail) Subject: using modules versus simply using multiple struts-config files I did search the archives and there is information about using multiple config files and separately about using full-blown modules too.

I'd rather not have to deal with that myself let alone training the other Struts newbies on my current tightly scheduled project. So, I guess I'll go ahead with my current plan to use multiple struts-config files associated with one entry in my web.xml file. The way I'll be setting it up makes it easy to switch to true separate module definitions later on anyway. Each logical module will already have its own subdirectory below the web root.

Starting point for a little test app (was: Suggestions for Calendar Popup taglib?)
In working on this, I've come up with a couple of things that would be very handy to have: 1) A simple dummy struts app which would be ready for me to plugin my taglib to test. I know that creating a little app won't take long, but a nice little starting point would be convenient. For an Intro to Struts seminar at my work, I extricated the struts-example webapp sources from the full source release for Struts 1.1. You would have to configure one build.properties file with the location of the external jars required to build the webapp. This is mostly just the ones in the Struts 1.1 binary release plus the servlet API jar. However, I added logging support for a rolling log file using log4j. So, you would have to provide the location of your own local copy of the log4j jar file too (or change the build file). Also, I did tweak the sources slightly to make it a better example of using multiple struts-config and message resource files for my own purposes. Other than that, it is pretty much the same mail reader example that ships with Struts 1.1. The zip file is just under 100K in size.

RE: How to set charset UTF-8
I added the following to test what encoding my Struts app is using % response.setContentType(text/html; charset=UTF-8); System.out.println(response.getCharacterEncoding()); % But it still print out the ISO-8859-1, why? How can I set the contentType to text/html; charset=UTF-8 This is just a hunch, but, I suspect you can't change the character encoding after you have started writing content to the stream. In that case, your best bet is to do this at the very top of the JSP page: %@ page contentType=text/html;charset=UTF-8 language=java % Also, there is another consideration if you are using Tiles. Again this is just a hunch, but, I suspect that you would have to have that directive as the first line of your Tiles master layout template JSP. The concept mentioned above for a single page applies to a Tiles page generated dynamically from multiple JSPs all writing to the same response stream. We ran into something like this using the Struts template custom tags with Struts 1.0 back in 2001. We were correctly setting the character encoding using the page directive on individual content JSPs, but, had left it off our master page layout template JSP. So, it never took until we tracked that down. Duh!

RE: logic forward problem
-Original Message- From: David G Friedman [mailto:[EMAIL PROTECTED] Sent: Thursday, September 11, 2003 8:18 AM To: Struts Users Mailing List; [EMAIL PROTECTED] Subject: RE: logic forward problem Your path looks like a tile. I wrote about this problem a week or two ago and you should've been able to find it in the archives of this group. It is documented on the logic forward tag as: Note: forwarding to Tiles definitions is not supported from this tag. You should forward to them from an Action subclass. Doing what the documentation suggests would work, but, it is not necessary to do the forward from an Action subclass. You can define an action mapping that your global forward points to that directly forwards to the tile definition without having to invoke an action class. This does work. I do this for the welcome JSP of my current webapp that needs to forward to the initial webapp tile definition like so: welcome.jsp: %@ taglib uri=/WEB-INF/struts-logic.tld prefix=logic % logic:forward name=welcome / struts-config.xml: global-forwards forward name=welcome path=/welcome.do / /global-forwards action-mappings action path=/welcome forward=page.welcome/ /action-mappings The page.welcome reference is a tiles definition reference. Granted, it is annoying to have to define the global-forward/action pairing to make this work. However, this is much simpler than going to the trouble of defining an action subclass just to do this where you would still need to define an action mapping anyway.

RE: Evil characters causing mischief in textarea and value attrib ute contents
Not 100% certain, but, I believe the default for the HTML form property tags was to *not* filter (i.e., filter=false) in Struts 1.0 and that was changed to default to do filtering (i.e., filter=true) in Struts 1.1. I am certain that the default for 1.1 is to do filtering. Original post did not say which version of Struts was being used. If my recollection of 1.0 behavior is correct, then that could explain the difference in behavior described here for similar JSP logic. In that case, you simply need to explicitly set filtering on in all your Struts 1.0 html:xxx form property tags. The filter utility function (can't recall from memory the class name/package, but, check the source for the html:xxx tags to find where it is defined in Struts sources) converts the quote character and less-than and greater-than characters to their character entity equivalents.

RE: No Keys Loaded For Validation
-Original Message- A really strange thing also is that if I copy the: registration.validation.missingCurrentCustomer=Please indicate if you are a current customer. into my default resource bundle, all messages display properly. Anyone have any idea what is going on? Since there is no way right now to specify the bundle for the message resource lookup, the default resource bundle is always used for these message resource lookups in the commons-validator packaged with the Struts 1.1 release. I'm not certain, but, one way around this in Struts 1.1 could be the use of modules. I do use multiple resource files, but, I don't use modules as of yet. I'm not suggesting you convert something to use modules just for this, but, you would have a separate default bundle for each module in that case. If that did work though, it would mean that you would have to replicate the common error message resources to the default bundle for each module. Which is the flip side of the same problem given the inability to specify the bundle for validations right now. What you really want is the bundle attribute in your validation elements that specify keys for message resources. I wouldn't be surprised if adding the ability to specify the bundle optionally when specifying message resources in your validation.xml is on the near future roadmap for the validation framework. I do know this issue has been raised before. Cheers, Van P.S. Heck, I'd even be willing to work on this particular feature myself in the commons-validator. I took great care in setting up my last project with separate config files and resource files for individual sections of the app only to find out that all validation messages had to go in the one default resource file for the app. :-( - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: RT expr value in custom tag
Eric,
What you are trying to do doesn't really require the JSTL expression
language. All you need to do is specify that runtime expressions are to be
evaluated for the parameter attribute of your custom tag in your TLD file.
If you were to look at any of the TLD files that come with Struts, you would
see plenty of examples of this. For example, here is the html:base tag TLD
definition that enables runtime expression evaluation for both the target
and the server optional attributes for the tag:
tag
namebase/name
tagclassorg.apache.struts.taglib.html.BaseTag/tagclass
bodycontentempty/bodycontent
attribute
nametarget/name
requiredfalse/required
rtexprvaluetrue/rtexprvalue !-- This is what I think is needed! --
/attribute
attribute
nameserver/name
requiredfalse/required
rtexprvaluetrue/rtexprvalue
/attribute
/tag
Runtime expression evaluation is what allows you to evaluate Java
expressions inside of %= ...% for your custom tag parameters. If you use
the JSTL expression language (EL), you don't use the Java expression tag.
They are two separate ways to refer to dynamic content for custom tag
attributes. To use the JSTL EL, you have to build your custom tag such that
it has EL support in it. If you really want to go that route, I haven't done
that yet myself. So, I can't help you with that. However, you can look at
how the contributed taglib (html-el) that extends the HTML taglib of Struts
1.1 to add EL support for the parameters of the Struts HTML custom tags does
just that.
Also, your example used the %= ...% tag correctly for a custom tag
parameter. However, many people initially stumble on getting this to work
correctly even when runtime expression evaluation is enabled because they
try to define only part of the custome tag attribute with the tag. For it to
work even when properly enabled for the attribute in the TLD, you have to
define the entire contents of the custom tag attribute value to be the %=
...% Java expression. If there is static content you want to include as
part of the attribute value, you typically use string operations inside the
JSP expression to concatenate and build up the final attribute value merging
your dynamic and static data.
Hope this helps, Van

Subject: RT expr value in custom tag
Good morning...
I'm trying to write my own custom tag library for Struts.
I've had some
initial success, but now I'm having some trouble.
I want to set an attribute value from the value of a bean
get. But what I
end up with in my tag is JSP code, not the value in the bean.
I.e.:
v:properties template=inputmode parameter=%=
UserSessionBean.getInputMode() %/
is not translated.
How do I get the result of UserSessionBean.getInputMode() in
my tag? Do I
need to implement Expression Language? Is there already a
utility class
somewhere in Struts 1.1 that would evaluate something like
${UserSessionBean.inputMode} for me?
Thanks.

RE: Problems Redirecting To Input Page After Vaildation Fails
Ciaran, When all else fails, cut and paste. :-) Seriously, I don't know of a way to make the input value dynamic. I wish it could be done like tile definitions with one action mapping extending another, but, I know that is not supported. So, the simplest solution is to have two separate action mappings for the one action class that supports both adds and updates like so: action path=/clientaction/add type=ie.sentenial.application.actions.ClientAction name=clientForm scope=request input=/pages/addClient.jsp attribute=clientForm /action action path=/clientaction/update type=ie.sentenial.application.actions.ClientAction name=clientForm scope=request input=/pages/updateClient.jsp attribute=clientForm /action You still get code reuse of your action class, but, you have to duplicate the action mapping specification. If you want to avoid duplicating the action mapping, the other way to go is to have a single JSP that supports both adds and updates with conditional logic in the JSP based on a mode parameter which indicates whether it is being used for an add or an update. - Van Mike Van Riper mailto:[EMAIL PROTECTED] http://www.baychi.org/bof/struts/ P.S. You don't need to specify both name and attribute values in your action mappings unless you want to store the form under a different name at request/session scope than the form configuration name. What you have done doesn't hurt anything, it is just not necessary to specify an attribute value unless the value specified for it is different than the name value. -Original Message- From: Ciaran Hanley [mailto:[EMAIL PROTECTED] Sent: Tuesday, January 27, 2004 10:57 AM To: Struts User Mailing List Subject: Problems Redirecting To Input Page After Vaildation Fails Hello can anybody help me with this problem I'm having please?

RE: Question on Frames within Tiles
Shitij, You can't insert a frameset document inside of a DIV element in the middle of a regular HTML page. The fact that this is not working has nothing to do with Tiles. It is simply invalid HTML. You can nest frameset documents, but, you would still need to reference the nested frameset document as the SRC attribute for a frame in an outer frameset document. In case it might help, here is a brief explanation of how tiles and framesets are successfully used together in the webapp that I am currently working on. I use framesets with tiles in a limited fashion. The bulk of my current application doesn't require the use of frames, but, I need to use them to integrate a third party solution as if it were a part of our application. I do this by displaying the responses from their server in a frame where the body content tile would normally be for a regular page. I have a separate master layout tile definition for normal pages and a different master layout tile definition for frameset pages. The master layout tile definition for the frameset pages has a PATH attribute that refers to a frameset document. The tricky part is that the SRC attribute in your frame definitions within the frameset have to make a separate request. Obviously, you can't have a tile attribute referring to another tile to insert at that point. Plus, I do everything through action mappings with no direct JSP references client side. So, this means that I end up with a lot of cookie cutter action mappings for the various frames that then simply forward to the tile definition for each frame. I was able to at least get some code reuse by inserting the same tiles for menus, footer, etc... into a page tile for each frame. For example, inserting the same menu tile into the header frame of the frameset as I use to insert the menu into the master page layout for the rest of the regular pages. There is probably a more elegant solution, but, I haven't invested much time or energy into this because I only need to use it for this one special case. So, I wouldn't necessarily emulate what I have done. However, you clearly can mix the use of framesets with Tiles.

Both these also need to be scrollable separately. My intention is to somehow include these frames within a Body tile. The other issue is that there is also a footer tile, which might need to include a frameset. The reason being the the control buttons need to always be visible(without having to scroll to view them).

RE: Questions about debug and info messages
Eric,
If you are using log4j, then you can configure it with a properties file. As
an example (minus some of my project specific settings), here is a simple
log4j configuration file that establishes a rolling log file. Notice near
the bottom where I set the struts and commons packages to the WARN log
level. This suppresses the INFO and DEBUG log messages for these packages.
# Usage: Specifies the configuration properties for log4j.
#
# Notes: This properties file should be placed somewhere
#inside the WEB-INF/classes directory.
# Create two appenders, one called stdout and the other called rolling
log4j.rootLogger=WARN, stdout, rolling
# Configure the stdout appender to go to the Console
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
# Configure the stdout appender to use the PatternLayout
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
# Pattern to output the caller's file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n
# Configure the rolling appender to be a RollingFileAppender
log4j.appender.rolling=org.apache.log4j.RollingFileAppender
# Configure the name of the logout for the rolling appender
# For Tomcat:
# log4j.appender.rolling.File=../logs/app-rolling.log
# For Weblogic:
log4j.appender.rolling.File=/logs/app-rolling.log
# Set up the maximum size of the rolling log file
log4j.appender.rolling.MaxFileSize=5120KB
# Keep two backup files of the rolling appender
log4j.appender.rolling.MaxBackupIndex=2
# Configure the Layout pattern and conversion pattern for the rolling
appender
log4j.appender.rolling.layout=org.apache.log4j.PatternLayout
log4j.appender.rolling.layout.ConversionPattern=%d{ISO8601} - %p %c - %m%n
# Set Struts/Commons log level
log4j.logger.org.apache.struts=WARN
log4j.logger.org.apache.commons=WARN
---
Of course, you have to configure your installation to read the properties
file. The simplest way is to include it inside the war at the root of your
class package structure where it gets picked up by default. However, you can
explicitly point to a properties file outside the war using command line
arguments to the JVM startup command for your servlet container. This is how
we have it setup for our production webapps so that we can reconfigure the
logging options without having to redeploy the war file again. See the log4j
docs for more information:

Subject: RE: Questions about debug and info messages
Thanks for the advice, but I'm using log4j. The API doc you
to which you
linked doesn't offer much help. I hacked a solution by
setting the message
level on the struts logger to warning in one of my
servlet's init method,
but surely there's a configuration setting (like a parameter
to the Action
servlet?) that will set the message level.

If you are using JDK 1.4 and not using log4j, then look in
JAVA_HOME/jre/lib for a file called logging.properties. Set
the .level to
OFF. The levels in descending order are: SEVERE (highest
value) WARNING INFO
CONFIG FINE FINER FINEST (lowest value) In addition there is
a level OFF
that can be used to turn off logging, and a level ALL that
can be used to
enable logging of all messages.
I haven't used log4j. Here is the struts docs:

Subject: Questions about debug and info messages
We have a torrent of debug and info messages coming out of
struts. I can't
find any documentation about how to turn them off. Two questions:
1. How do I turn off debug and info level messages?
2. Where is that documented?
Thanks,

RE: Pls help me in configuring common logger

You can either remove the commons logging properties file or explicitly configure it to use log4j. As long as you setup log4j properly in your runtime environment, the commons logging logic will use it by default unless you have a commons logging properties file that explicitly specifies a different logger implementation.

RE: Pls help me in configuring common logger
Sougata, I can point you in the right direction, but, I don't have time to spell everything out for you. I think you need to do some work on your own reading the commons logging docs. You need to understand the commons logging package and how to configure it to use log4j or the native logging facilities in JDK 1.4. When I mentioned the simple logger, I was referring to this implementation of org.apache.commons.logging.Log: org.apache.commons.logging.impl.SimpleLog If you are using the commons logging package, it has a properties file you can use to specify which Log interface implementation to use. I could be wrong, but, when this file is not provided my experience has been that it will automatically detect the presence of a properly configured log4j and instantiate a org.apache.commons.logging.impl.Log4JLogger. If a properly configured log4j is not detected, it will default back to the SimpleLog implementation.
