Re: Using Tiles outside of an ActionServlet
Doh - I guess I wasn't clear enough. I want to have the Requests for the html pages (Section2) forwarded to a standardLayout page which uses tiles to provide consistent screens. The originally targetted html page needs to be included/embedded within the standardLayout page. David, I guess I could be missing something (wouldn't be the first time), but I don't think your solution will give me that will it? Its more about allowing the html files to themselves contain a tile. If I could somehow get the html requests to be forwarded to a single page, then I could do it. But I can't see how to do this without using a 2nd ActionServlet which brings me back in the original pain. William - Original Message - From: David G.

Re: Multiple input forms - one action - one validator, how?
If you want different types of validation to be performed before the Action is executed, then assuming you are using the Struts Validator I recommend that you : 1) ensure your Forms extend from ValidatorActionForm, 2) Create separate ActionMappings for each type of validation you want to perform (each ActionMapping uses the same Action class). 3) Create the various validation specifications in validation.xml, each keyed to the new ActionMappings.

[OT] Re: Need an alternative to bean:define
Many times newer developers don't care so much about the academics of what is proper. For example, they see the Struts tags and like them, and then become attached to them. It can be disconcerting to them to find out that they are using an outdated technology so soon after they have discovered something that made development more efficient and more fun than it had been before. The Java community at large should remain aware of this phenomenon. I say, if a tool is proven to work well for a particular job, it belongs in the box. In the context of programming, this presupposes some level of support and acceptance for the tool in the community. I have been doing Swing/AWT development for about three years now. Over and over again I have implemented the same types of interface devices, scouring the Swing source code, examining stack traces and ever perfecting my use of Threads. I am just now beginning to get good at it. Every time a new Swing release comes out, I can't wait to find out what bugs have been fixed, what new devices are available for Linux that have been taken for granted on Windows, and the like. At the same time I see libraries emerge that promoters claim are the result of Swing's shortcomings, and I mostly find it ridiculous, given the context (time) and my own experience (Swing and Graphics 2D can do all sorts of amazing things). I hope Sun isn't affected much by it and continues on building and documenting Swing. Everyone is in too much of a hurry to go on to the next tool. Programmers who end up building things of substance reach for their trusted tools, devices, paradigms, etc., when they are inspired and want to get something done with confidence. Some of the best Java GUI applications I have seen will run on a (pre-Swing) 1.1 JVM, and here there are people saying Swing is a wash. Based on what I have read as a subscriber to this list, I conclude that many Struts users feel the same way about Struts as I do about Swing. They (myself included) greatly appreciate James' taglib tests, the ongoing efforts to build a better dispatch action and the work of all other contributors (not only committers). They breathe a collective sigh of relief when they see that Craig is writing papers about Struts 2. Erik P.S. This is no attack on Eddie's advice to prefer JSTL to the Struts tags. I often give the same advice. James Mitchell wrote: As an FYI. I don't think it is wise to say that the Struts taglibs will be going away.

Re: Struts Best Practices
hi rajagopal, dynaforms are useful for putting something together quickly, but I find them less useful than hardcoded form classes sometimes, especially if there are many form fields. The way to access some data from the form submit in your action is usually so for a dynaform: addressDTO.setLine3((String) accommForm.get(line3)); and for a hard-coded formbean: addressDTO.setLine3(accommForm.getLine3()); If find that the hard-coded formbean is easier to code with in IDEs like Eclipse, due to better auto-completion, less room for typo mistakes etc. hth Adam On 11/05/2004 06:32 AM Y, Rajagopal wrote: Ok...Fine..

Re: How use the BeanUtils and interface converts
Writing a date converter is pretty simple; the
only reason there isn't one included in the
beanutils distribution is that there's not a very
easy way to configure the date format in a
universal way.
Below is an example. This one is implemented as
a static inner class within the only class which
uses it, but you could do it differently:
static class SimpleDateFormatDateConverter
implements org.apache.commons.beanutils.Converter
{
String dateFormat = null;
SimpleDateFormatDateConverter(String dateFormat)
{
this.dateFormat = dateFormat;
}
public Object convert(Class clazz, Object obj)
{
if (obj == null) return null;
if (obj instanceof java.util.Date) return obj;
String toParse = obj.toString();
if (toParse.trim().length() == 0) return null;
java.text.SimpleDateFormat fmt = new
java.text.SimpleDateFormat(dateFormat);
try
{
return fmt.parse(obj.toString());
}
catch (Exception ex)
{
throw new org.apache.commons.beanutils.ConversionException(ex);
}
}
}
Then, elsewhere in your Java code, you would
register the converter doing something like this:
String dateFormat = -MM-dd;
ConvertUtils.register(new
SimpleDateFormatDateConverter(dateFormat),
java.util.Date.class);
Since this code was written, beanutils has made
good progress away from using static methods for
everything, which makes it easier to have
Converters in different parts of your app that
behave differently. See
http://jakarta.apache.org/commons/beanutils/api/index.html
and more specifically
http://jakarta.apache.org/commons/beanutils/api/org/apache/commons/beanutils/BeanUtilsBean.html#BeanUtilsBean(org.apache.commons.beanutils.ConvertUtilsBean,%20org.apache.commons.beanutils.PropertyUtilsBean)
for the doc details.

Re: [****] Including a Struts action in a JSP - IllegalStateException / truncated response issue
Thanks for the information, Jeff. Unfortunately, though the Tiles Advanced Features Guide indicates it is possible to include multiple Struts actions (using tiles:insert) on one page, I _still_ get the IllegalStateException Response has already been committed. We often need to prepare data to be shown by a JSP page. In the MVC framework, the controller prepares data (in the model) to be shown by the view. Translated to Tiles and Struts, we can use a Struts Action as a controller, a JSP page as a view, and combine both in a Tile. So, when you insert the Tile, the Action is called before the JSP page is displayed. Now, your complex web page can be made of Tiles fed by controllers (one sub-controller for each Tile). This approach is better than one single controller for all Tiles of the page, because it really allows building autonomous Tiles, without worrying about how to fed (sic) them all. - Tiles Advanced Features Guide (http://www.lifl.fr/~dumoulin/tiles/tilesAdvancedFeatures.pdf) This is describing exactly what I want to accomplish and the reason for it but I keep running into the same committed response problem. Is it possible that this is a container issue rather than being a Struts issue? Can someone else confirm that c:import and tiles:insert both cause an IllegalStateException when including more than 1 (actually try 3 or 4) Struts action on the same JSP?

So I thought I have to do it by using getServletConfig().getServletContext( ).getResourceAsStream(/WEB-INF/config-file.xml) but I did not figure out how to do that because getServletCofig only works in Servlets, not in static beans. Can you help me? Thanx in Advance, Lukas - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: [****] Including a Struts action in a JSP - IllegalStateException / truncated response issue
Can't really comment on Tiles since I don't use it, but this recent thread may be of interest: http://marc.theaimsgroup.com/?t=10976831933 Quoting Parke Jeff [EMAIL PROTECTED]: Thanks for the information, Jeff. Unfortunately, though the Tiles Advanced Features Guide indicates it is possible to include multiple Struts actions (using tiles:insert) on one page, I _still_ get the IllegalStateException Response has already been committed. We often need to prepare data to be shown by a JSP page. In the MVC framework, the controller prepares data (in the model) to be shown by the view. Translated to Tiles and Struts, we can use a Struts Action as a controller, a JSP page as a view, and combine both in a Tile. So, when you insert the Tile, the Action is called before the JSP page is displayed. Now, your complex web page can be made of Tiles fed by controllers (one sub-controller for each Tile). This approach is better than one single controller for all Tiles of the page, because it really allows building autonomous Tiles, without worrying about how to fed (sic) them all. - Tiles Advanced Features Guide (http://www.lifl.fr/~dumoulin/tiles/tilesAdvancedFeatures.pdf) This is describing exactly what I want to accomplish and the reason for it but I keep running into the same committed response problem. Is it possible that this is a container issue rather than being a Struts issue? Can someone else confirm that c:import and tiles:insert both cause an IllegalStateException when including more than 1 (actually try 3 or 4) Struts action on the same JSP? Thanks again for anyone who can help, Jeff I think that it is unusual to directly include Struts actions in JSP files. When composing pages of different parts, Tiles is the much more common approach. The standard usage of Tiles is to include JSP files directly, but you can use tiles to include Struts actions in JSP files. (See Section 5.2 of the Tiles Advanced Features guide, a PDF file, at http://www.lifl.fr/~dumoulin/tiles/tilesAdvancedFeatures.pdf.) -- Jeff Parke Jeff wrote: I'm still having trouble including a Struts action into a JSP (c:import url=/someAction.do /). I've tried using absolute URLs, passing the jsessionid to ensure that the session is not lost, but the request context is different between the JSP and the included action, so this not suitable for many situations. I've also tried upgrading to Struts 1.2.4. This does not resolve the Response has already been committed issue when including more than one Struts action in a JSP. The app server is using JRE 1.4.1_03-b02. Can anyone tell me whether they have seen this situation before? How common is it? Is it unusual to include Struts actions in JSPs? Anyone?

Struts html:checkbox
Hi,
Sorry if this problem has already been solved, I cannot seem to find
anything in the Struts List Archive...
I have an Action class that sets, in the ActionForward method of the
said Action class, an attribute of an object in the request scope to
push it to the presentation layer (JSP). In the JSP form, I use
exclusively Custom Struts Tag to display data from the object in the
request scope.
Everything works greatly except for that
html:checkbox property=propName
value=${boolValue}/html:checkbox which doesn't seem to render the
checked=checked attribute. The value of the value attribute is
set to true... but for some reason, I can't seem to get it render
checked on load.
Is there a way to get a html:checkbox render as checked upon JSP load?

Re: Multiple input forms - one action - one validator, how?
Hi Can! actually, i can't think of any other 'standard' solution (using the actionValidator you still would need the single input attribute) Maybe you could use a combined change of ActionMapping and ValidatorActionForm. Subclass those and set them in your config files. Change the ActionMapping so that getInputForward returns the forward you want. In validation of the form set this to what you want it to be. Let me know if it works ;) hth, axel On 2004-11-05 at 12:10:01 +0100, Can Gencer wrote: Hello, I have multiple forms that point to the same action.

RE: Struts html:checkbox
Set the corresponding form property to true prior to loading the page.
If the actual form property value equals the ${boolValue}, then the
checkbox should render as checked. That is, it should produce the
appropriate HTML which should render the checkbox as checked.

I'd like to try to bring all the relevant information from these posts together and then ask for help in identifying a viable workaround. I apologize in advance if this issue is well known and understood and I just missed the best resources on the subject. Goals: 1) To build a Struts application where _every_ request to the application goes through a Struts action that collects and packages data then forwards (using Struts ActionForward's) to a JSP. 2) To be able to include one or more Struts actions in any given JSP (ie: c:import url=/someAction.do /). Behavior when implementing these goals: 1) Usually, when executing a single include of a Struts action on a JSP, everything works fine though sometimes there are problems (as listed below). 2) When including more than one Struts action on a JSP I get an IllegalStateException - Response has already been committed. 3) Sometimes, when a JSP only includes one Struts action, the first x bytes of the response will be missing when it is returned (without exception) to the client. Relevant issues (correct me where I'm wrong): 1) Including (jsp:include, c:import, etc.) a JSP/Servlet on a JSP sometimes (always?) causes the response to be committed because includes use RequestDispatcher.include() which in turn commits the response. 2) Forwarding a request using an ActionForward from a Struts action to a JSP can not be done when a response has been committed. 3) Increasing the response buffer size has no effect on these issues. 4) Using the include directive (%@ include file=filename %) won't work because that includes source a translation time. 5) It has been reported that using tiles:insert does not (fully/always?) resolve the problematic behavior. 6) Using absolute URLs with c:import prevents the response from being committed because the context of the request is assumed to be independent. The visibility of an authenticated, populated session can be affected by passing the jsessionid in on the URL. This seems to be the only viable workaround though I haven't tested it thoroughly yet.

This approach is better than one single controller for all Tiles of the page, because it really allows building autonomous Tiles, without worrying about how to fed (sic) them all. - Tiles Advanced Features Guide (http://www.lifl.fr/~dumoulin/tiles/tilesAdvancedFeatures.pdf) This is describing exactly what I want to accomplish and the reason for it but I keep running into the same committed response problem. Is it possible that this is a container issue rather than being a Struts issue? Can someone else confirm that c:import and tiles:insert both cause an IllegalStateException when including more than 1 (actually try 3 or 4) Struts action on the same JSP? Thanks again for anyone who can help, Jeff I think that it is unusual to directly include Struts actions in JSP files. When composing pages of different parts, Tiles is the much more common approach. The standard usage of Tiles is to include JSP files directly, but you can use tiles to include Struts actions in JSP files. (See Section 5.2 of the Tiles Advanced Features guide, a PDF file, at http://www.lifl.fr/~dumoulin/tiles/tilesAdvancedFeatures.pdf.) -- Jeff Parke Jeff wrote: I'm still having trouble including a Struts action into a JSP (c:import url=/someAction.do /). I've tried using absolute URLs, passing the jsessionid to ensure that the session is not lost, but the request context is different between the JSP and the included action, so this not suitable for many situations. I've also tried upgrading to Struts 1.2.4. This does not resolve the Response has already been committed issue when including more than one Struts action in a JSP. The app server is using JRE 1.4.1_03-b02. Can anyone tell me whether they have seen this situation before? How common is it? Is it unusual to include Struts actions in JSPs? Anyone?

Re: Hi
Hi,
I am able to display the text field for phoneNumber now. The code i wrote is
logic:iterate name=autoForm property=menuEntries id=menuEntries indexId=idx
tr
td valign=middle
bean:write name=menuEntries property=key/
html:hidden name=menuEntries property=key/
/td
td valign=middle
html:text name=menuEntries property=description size=15
maxlength=15/
/td
td valign=top
html:select name=menuEntries property=menuAction
onchange='%=showOrHidePhoneNumber(this.value, +idx+);%'
html:option value=Select A Action/html:option
html:options name=actionNames labelName=actionNames/
/html:select
/td
td
div id=%=idx% style={display:inline}
html:text property=phoneNumber size=15 maxlength=15/
/div
/td
!-- /tr --
/logic:iterate
function showOrHidePhoneNumber(actionselected,index) {
alert(index);
alert(actionselected);
if(actionselected==Transfer with prompt) {
document.getElementById(index).style.display = inline;
} else {
document.getElementById(index).style.display = none;
}
}
I have to call showOrHidePhoneNumber(actionselected,index) when the page loads.
And it should not display the textfield for phoneNumber for all 11rows as the default
option is not Transfer with prompt. Help me figure out this function.
Thanks,
Latha

So, what should i change this to.
Thanks.

Hi,
i tried using indexed=true for
id=menuEntries
indexed=true/
size=15 maxlength=15 indexed=true/
indexed=true
Select A Action
labelName=actionNames/
maxlength=15/
I have a menuentry[] menuEntries property in formbean.
so i need to index for description and key also.
There is indexed attribute for html:text but not for bean:write
So i used html:hidden indexed=true
I have get and set methods in menuEntry class for key, description and
menuaction.
MenuEntry[] menuEntries = form.getMenuEntries(); in action class.
tried retrieving the menuEntries[] in the action class.
I get java.lang.NullPointerException
at
org.apache.commons.beanutils.PropertyUtils.getIndexedProperty(PropertyUtils.
java:515)
so if I use indexed, should there be 11 different get and set methods
because name of the property changes name=menuEntries[5].menuAction.
Is there anyother way without using indexed, but send index of the
property to the onchange method.
Thanks,
Latha.

Hi,
I have a logic:iterate tag in my jsp.
size=15 maxlength=15/
Select A Action
labelName=actionNames/
I have 11 rows to iterate.
for each html:select i have to invoke onchange method such that
depending
on the selection(for example if have options a,b,c,d in dropdownlist, i
have
to display a textfield called phonenumber only for options a,c.). My
problem
is i have to send some parameter in the onchange method, but since it is
iteration every iteration has same propertyname,
I have menuAction as property name for htmlselect.
I should be able to get the phonenumber only for the options i sent when
i load the page.(Iike edit page)
I would appreciate if anyone can help me.

struts tiles tab and border
For page or summary tab, a tab is label of words. Can I change it to an image file? If not, can I add an image file? Moreover, there is a purple border after clicking a tab. Can I change the border color and even remove it? Thanks - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Authentication and Authorization
There used to be (haven't checked on it for a while) a project called Security Filter that was a security database implementation you could package with your application. I believe it was a SourceForge project. One of the projects I'm currently architecting has need for specialized security - above and beyond what our CMS will do (CMS will handle it to the application on a per-user bases). I'm implementing this through use of a Filter and a HTTPRequestWrapper. Oh, and I've tossed in a custom implementation of Principal to make things nice and tidy. Once complete I'll be able to leverage standard calls like isUserInRole and getUserPrincipal to deal with my users. The nice thing is, because of the nature of filters, once I'm done with this I can jar it up, drop it in any application I write (and add to the web.xml of that app) and use the exact same thing for many other applications (I have at least 2 to get out this quarter ... they seem to be finding new ones for me to write all the time)! Gotta love real reuse in actual practice! ;-) Filters fit a lot of problems really nicely - even if you don't build a request/response wrapper to go along with them. They're extremely handy for the problems that they do solve.
