XML/XSLT Question - Help!
I have a question regarding the use of XML/XSLT. Please correct me if I am wrong, but it is my understanding that XML does not directly support graphics. Apparently, a new XML standard called SVG is currently being reviewed by w3 for approval (hasn't been adopted yet) which uses scalable vector graphics to display a page, which is pretty cool, but even that doesn't directly support the use of gifs and jpgs unless you convert all the graphics to vector graphics (svg format) Is this true, or can I place graphics in XML and then define them in the XSL doc? If so, is this an acceptable technique? -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
The Struts-way Problem......
I was just thinking about how the Struts-way is to have everything go through an Action class first and then redirect to a jsp. If you do this, then the following problem could occur: If you are on Page A which contains a list of users and one of the columns is Gender for example, and you leave the page to another to change the gender of user X, and then use the Browser's back button to go back back to the list page. If you then hit refresh, the user list will still show the old Gender for user X. This is because the Action is not called at this point, only the jsp is refreshed. Does anyone know of a Struts-way to fix this? -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Depending on which browser
you use, and the data on the page, the back
button may cause (or ask) the page to
reload. However, some browsers (like IE) only
display a snapshot of what the last page
rendered to. Therefore, you
cannot use scriptlets or the action class. However, you are able to kick-off
javascript. If you can gaurantee that your users
will have javascript enabled, you can
write a simple test to see if this page was
already displayed to the user. You could
check a flag (hidden field) when the page loads.
If the flag is true, then use the javascript to reload to your desired page. HTH, Pete

Re: Unchecking radio buttons?
I know. Struts doesn't handle unchecked boxes very well. In fact, it doesn't understand them at all.

Re: Unchecking radio buttons?
All you really have to do is to manually set the checkbox value to false after you display the current value: ie: html:checkbox property=mycheckbox / // notice that no value is set % MyForm.setMycheckbox(false) %// do this after you display the above line in same JSP where: protected boolean mycheckbox;// mycheckbox is of type boolean (small b) and you're in business. If the checkbox is already checked it will still be checked when you do a submit, because it will read the value on the page. If you uncheck it though, it will be false which is correct too. :-) - Original Message - From: Laine Donlan [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, May 08, 2001 2:30 PM Subject: RE: Unchecking radio buttons? Here is some code that I submitted to the dev list a while back. It might be useful as it solves the problem of the 'unchecked' checkbox submit. Hope it helps. Laine - In order to capture the act of a user unchecking checkboxes and to initialize the checkbox as checked/unchecked with non boolean values I made a couple of changes to the org.apache.struts.taglib.html.CheckboxTag. Basically the changes consisted of: 1) Using the supplied value attribute to match against the bean property value and generating the 'checked' attribute accordingly. If the value is not supplied then the previously implemented method of checking 'on', 'true', or 'yes' is performed. So I do not think that default behavior should be affected. 2) Added support for two new attributes - submitUnchecked (boolean) and uncheckedValue (String). Neither of these attributes are required and the submitUnchecked defaults to 'false'. If a user chooses to submit unchecked values then two form inputs will be generated that facilitate this function. See below for an example: Tag notation - html:checkbox name=bean property=indexedBean.property submitUnchecked=true uncheckedValue=0 value=1/ Generated HTML - input type=checkbox name=indexedBean.property_checkBox value=1 onclick=(this.checked?this.form['indexedBean.property'].value='1':this. form['indexedBean.property'].value='0') input type=hidden name=indexedBean.property value=0/ (where 0 is the current value of the bean property) So in this scenario the actual checkbox param in the request will be ignored and the hidden input will be used to maintain the bean property that the user wishes. In the case where the user does not provide the two new attributes the html will be generated as it is today with the exception of the determination of the checked or unchecked mentioned above. I could not see how this functionality was present in the current checkbox tag without explicitly declaring two tags and adding javascript to the checkbox tag. Even then some scripting may be required to differentiate between the two inputs and to initialize the hidden one. If I missed something could someone point me in the right direction. I have attached the CheckboxTag.java file for review and use if anyone is interested. Thanks. Comments would be appreciated.

Re: Drop-down list
Trying to use Multiple="true" attribute for html:select
Help!
O.k. so I declare it like so:
protected String[] providerName;
Then I get it:
public String[] getProviderName()
{
return (providerName);
}
Then I set it:
public void setProviderName(String providerName[]) {
{ this.providerName = providerName; }
}
What am I missing?

Add the attribute to your tag like so:
html:select ... multiple="true" ...
and make sure the corresponding property in your form bean is an array of
values.
See the docs for more details:
http://jakarta.apache.org/struts/struts-html.html#select
Hope this helps.

I'd remove all the square brackets. If you want to keep them, the
parameter
type in setProviderName should be String[].
I don't know for sure though.

Nick Pellow wrote:
I was considering an approach where coders wrote validation code in Java
(we all know java!)
yet the Struts framework executed it. You would extend or implement a
common java class/interface defining a single method,
public ValidationErrors validate(); say.
That is then mapped to the form field in an xml file somewhere.
Struts, however could ship all the standard validations (such as Strings
to ints)
together.
It is something I have not given much thought to yet, but would be
interested in
exploring further.
Beyond the thinking expressed so far on this thread, I've had two
additional ideas
for functionality that should be included here:
* Optional generation of client-side JavaScript code to do the kinds
of validations that make sense (required fields, number formats, etc.)
closer to the user.
* The JavaBeans spec includes the concept of a PropertyEditor, which
lets you define a custom conversion between String and a bean data type.
JSP 1.2 supports this when doing attribute conversions -- we should look
at whether it can help us in the conversion/validation arena as well.

Re: Volunteer for Validation Framework
I have a lot of experience using validation. I am of the opinion that if possible validation should be done client-side using javascript. Is there a way to implement this by extending Struts? If so, I would be very interested in helping. Currently, I am working on expanding Struts Custom Tag Library. I've added Pattern, IsRequired, and errorMessage to Struts-html.tld and modified the Struts source files to accomodate for this. It uses pattern because I am using Perl5 regular expressions to send the validation parameterss to the Form bean.

I added some basic support for constants (global and on the Locale level). I also made the validations more configurable. You can define what class and method should do a type of validation. I added a depends attribute to the validation definitions so you could say that checking for an integer shouldn't be done until required validations are done. It's probably needs some work on the logic, but it seems to be working on the basics. Also a number of objects could be created and cached somewhere. I also started on some methods to do basic type checking. It's just some numeric primitives right now and a date. I added an example page to the sample webapp doing the type checking. The code and sample web app is on my site. I have a basic explanation, but I think it's lacking since I've added so much, but the examples should help. http://home.earthlink.net/~dwinterfeldt/ David __ Do You Yahoo!?
