Re: More validation woes
In both cases, you're returning an ActionForward that has no idea of the
environment in which it was created. So, why not forward to another
page (like error.jsp)?
Yansheng Lin wrote:
That's what
return (new ActionForward(mapping.getInput());
returns. An ActionForward to the jsp that generated the error.
Ok, take a look at the following code. You see the difference? findForward can
forward you to any page, but not mapping.getInput().
public ActionForward execute() {
...
if (!errors.isEmpty())
{
saveErrors(request, errors);
//return (mapping.findForward(error));
return new ActionForward(mapping.getInput());
}
}

I don't think it works. An Action.execute() returns an ActionForward.
ActionMapping.getInput() returns a string. Type conflict.
Or, am I doing something really dumb?

OT: struts-user archive question
I need to solve a problem associated with the Validator. If I use the online search engines, I either get too little or too much info -- and I have yet to find anything that pertains to my question. Is there a mechanism whereby I can grab a tarball (or zip) of the last 10,000 messages? I know about struts-user-get.min_max@jakarta.apache.org, but that is limited to 100 messages per query... - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Validator problem?
While I'm waiting for an answer to my OT: ?, I figured I'd come out and ask the question that's been bothering me for a few days. First, the setup: Form: Contains a number of fields. Indirectly extends ValidatorForm. There are some processes in place not necessary for this discussion, but cool enough for me to talk about. I use EJBGen to take the Entity bean and produce a ValueObject. I then use a custom generator that works off of the *VO to produce a *FormBase that decorates the VO (composition, not inheritance) and allows full Struts integration (handles Date-StringDate conversions). The end Form extends the FormBase and adds any requirements needed by the JSP (like readonly lists for dropdowns, boolean-String converters for Y/N database columns, etc.) For the purposes of this discussion, there are 36 attributes. JSP: Contains a block of the common fields, followed by some nested:equals tags to add type-specific information. NOTE: This is *not* a wizard -- there is no page-by-page progression. Only one page (as the user requires). The nested:equals tag relies on one of the form attributes. Struts: validation.xml contains one form with a number of field definitions. Some of these are required. Some are 'at least one of 2 checked' required (for which I added a custom Validator method and associated validator JavaScript). Problem: When I submit, Struts returns an error on the server side because fields that aren't included in the JSP are marked as required. The solution I'd like to see is a Validator that only validates on fields that are included in the Submit. A solution that I'm trying to avoid (and may fail) is to duplicate all of the common validation rules in validation.xml for each 'type' of form. In struts-config, I'd just add more actions with the same form base. Though I don't know if that would be enough. I really don't want to move away from the single DispatchAction tied to a single Form with only 2 struts action defs (w/ and wo/ validation). Any suggestions? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Struts: a Graphic Artist blessing or curse?
My last JSP job did not suffer that problem -- the graphics designer also did 100% of the JSP work. This on a post 1.0.2 nightly with integrated nested extensions (I had convinced the client on the benefits of the nested extension and they prefered integrated rather than in a separate package). The data architect did 100% of the database work (and some of the use case work -- he was quite good at high-level analysis). The programmers did 100% of the coding. The only aberration was me (the chief architect) -- not only did I do analysis through detailed design (using TogetherJ for class and sequence diagrams), I also did a fair amount of coding. Contrast that with my last .NET job: The graphics designers did strictly static HTML work. The converion to dynamic HTML, database work and coding was shared by everyone else (not much of a design to start with). [EMAIL PROTECTED] wrote: Haha!

Dear Struts supporter, There seems to be a real world problem with using Struts (well, not really Struts, but JSP Tag Libraries). It seems despite zero java coding on the JSP pages, those 'funny' tags are still not digest-able by average graphic designers. I mean, if they were to use Macromedia DreamWeaver, it would not've rendered the look and feel if the tags were something like this: - html:img page=/nice.gif altKey=Nice/ html:html locale=true /html:html html:link page=/another.jspbean:message key=another.title//html:link As opposed to the native standard HTML tags? I'm really not sure whether Macromedia or any other popular graphic artiste tool would render these Struts JSP pages properly. Anybody here has any experience solving this real world problem? Thanks.

Let's take it one step further and make the Map a 1st-class object.
After all, shouldn't all knowledge of how to recognize a driver's
license be localized to a single class? Then the external interface can
be a simple as isValidLicense( state, licenseString );

Subject: [OT - Java] How can I do this in Java?
OK - off topic, but Sun's java forum sucks, and there are an incredible
number of Java guru's on this list, so I thought I'd throw this out here.
(That and I am using this in a custom validation routine :-))Any help
would be GREATLY appreciated!
Here's the scenario - I've got a series of static constants that represent
Java regular expressions. These RE's are used to validate driver license
formats for the 50 states + DC. The strings look like this:
public static final String AK = ^[0-9]{1,7}$;
public static final String AL = ^[0-9]{7}$;
public static final String AR = ^[0-9]{8,9}$;
public static final String AZ =
^[0-9ABDY][0-9]{8}$|^[A-Z][0-9]{3,6}$|^[A-Z]{2}[0-9]{3,5}$;
public static final String CA = ^[A-Z][0-9]{4,7}$;
public static final String CO =
^[A-Z][0-9]{1,6}$|^[A-Z]{2}[0-9]{1,6}$|^[0-9]{9}$;
etc. etc. etc.
On my form I have a drop-down box of states, and a field for the license
number. In my custom validator routine, I pick up the value of the state,
and build a string to represent the constant - i.e.
private static boolean validateDriversLicenseNumber(String
licenseState, String licenseNumber)
{
String licenseConstant = Constants. + licenseState;
I then want to use licenseConstant in a Pattern / Match:
Pattern p = Pattern.compile(licenseConstant,
Pattern.CASE_INSENSITIVE);
Match m = p.matcher(licenseNumber);
return (m.find());
}
Obviously the line String licenseConstant = Constants. + licenseState;
does not give me the value of Constant.state name; the question I have
is,
is there a method (or something) that will allow me to build such a
string,
and return the value (i.e. the regular expression)? Or is there a better
way of doing this?
TIA!
