Extending the struts config
Eddie,
you said once (if I remeber correctly), that you extended the
struts-config.xml to accommodate your own configuration settings.
I would appreciate it if you took a minute or two in answering my
questions :-) :
Did this involve a lot of overhead?
Are you having to change the dtd? - which would require you to update
every time you installed a new struts-version.
Is there an easy way to retrieve the values from you action?
I would be equally happy if you directed me to a good documentation that
might be of some help.
Thanks in advance,
Regards,
Michael

Add a Collection to your form bean. Add getter and setter methods to the
form bean. Add code to your action class (usually a prepare-type action) to
look up the data (or call the appropriate facade/delegate method) and
populate the collection on the form. Modify your resultant jsp to use the
Collection in an <html:options> tag within an <html:select> tag. Check the
docs on the struts site for specific details or reply with more specific
questions.

I don't know what <html:optionsCollection> is, but for your purposes, I
would use <html:options> backed by a Collection as I mentioned earlier.

Not worried.
But something I'm planning for the future should help everyone with API's
jar versions and examples. A little project I'm dreaming up. I'm sure If ask
ask for a show of hand I'll get this project off the ground.
Still I've made progress.
Not sure what's the difference with:
<html:optionsCollection
<html:options
But if I dig I might find out.

Don't worry, Mark. If there were an adequate example in the Struts docs, you
would have a better idea how to start and what questions to ask. However,
you have to use this list or scour the internet for examples.

Eddie Don't do my research um - I got a PhD in Molecular Physics and
Nanotechnology for doing some very good research. Oh and then there was Bell
Labs.
Oh never used Google whats that ?
With 52,000 mails and a very poor interface, a.k.a you can't even order by
date ?
I'll know not to post so fast in future for fear of being made an example of
by Eddie.
However if the framework is so simple why is there 52,000 mail comparable
with Tomcat ?

Regarding menus, I use struts - menu from sourceforge.
You can see struts menu runing at baseBeans.com live.

Try "Struts html:option" - works super. I actually did try it :-) I
didn't get as good of a return as I expected though :-/ I'm sure I
could refine it better and get a better return, but, as I was just doing
it to ensure I was getting back relevant data, I didn't investigate it
thoroughly.
The point is valid though :-) Far too few people actually take the time
to do any research on their question before asking. Chances are, if you
have a problem, someone has already run into it and likely solved it as
well. The first thing I do when I hit a "rough spot" is look around -
Google is my first stop. I'll try a few (anywhere from 3-5) different
permutations of relevant keywords (doing things such as removing that
troublesome colon) and see what I get. Most of the time that's ...
plenty :-) There are times it does not suffice.

When you put "html:option" in the search box it doesn't work. At least, it
never has for me. The ':' screws it up and searching on "option" or "html
option" is not viable. I'm going to reiterate that if the Struts docs had
good examples of implementation, a lot of repetitive questions could be
avoided. I would gladly update the documentation if I had the time.

Re: Dynamic select menu in JSP
Posted by Eddie Bush <ek...@swbell.net>.
That's a very valid point. Did you, in the course of asking to be put
on the list, actually read:
http://www.tuxedo.org/~esr/faqs/smart-questions.html
... or just look for the link that said "sign me up!" ? :-) Not trying
to be difficult - I'm just honestly curious ;-) I would be willing to
wager (and I'm not a betting man) that if you searched for html:option
you'd find several suggestions to "use html:options instead" - and some
of even those likely have explicit details as well :-)
I'm not in the habit of holding grudges, so don't feel *too bad*.
You're far from the first to ask a repetitive question, and I doubt
you'll be the last. It would be nice if folks exercised their
STFW-related brain cells though :-)
(Sorry - not trying to single you out - this particular question is
occassionally asked and answered as many as three times in a single day
though - I can't remember the last week that passed without at least a
single query on it.)
Peace ;-)

*sigh*
There have been a number of topics going on about doing such things
lately. Obviously, using the <html:option> tag is less than ideal.
Have you looked at <html:options/> yet? I think you'll find a much
better implementation possible using it instead of <html:option/>.
STMA (Search the Mail Archive) - most notably the last 7 days. You're
guaranteed to find a message that gives explicit usage instructions. A
hint: populate the property that represents your options in an action.
If that doesn't make sense now, it will once you do some research on
how to use <html:options/>. If it doesn't, just let us know.

Re: Dynamic select menu in JSP
Posted by John Owen <jo...@hotmail.com>.
Here's an example of the jsp code :
<html:select property="defaultEmployee">
<html:options property="employeeValues"
labelProperty="employeeLabels"/>
</html:select>
defaultEmployee is a String representing the 'selected' value,
employeeValues is a Collection that contains the values for each option,
employeeLabels is a Collection that contains the labels displayed in the
drop-down. These variables are all defined in the form bean used by the jsp
defined in the action mapping in your struts-config.xml. The Collections are
populated in an action class that is used to prepare the form before the
user sees the jsp page.

Dynamic select menu in JSP
Posted by Mark Ayad <ma...@javamark.com>.
I would like to know the best method to populate a form in a JSP page with
dynamic select menu, where the number of options in the select depends on a
query to the database. Specifically where is best to place the functionality
?
<html:select property="singleSelect" size="10">
<html:option value="Single 0">Single 0</html:option>
<html:option value="Single 1">Single 1</html:option>
.......
.......
<html:option value="Single n">Single n</html:option>
.......
</html:select>
Previous to Struts I would have looped aropund a resultsset.
What do people use ?

I believe that the warnings are still issued, but Struts works
anyway. Here's the CVS log for ActionServlet:

So it may be that you need to disable the validating parse in the web.xml file.

Hi,
wow - that´s just the kind of answer I was looking for! I´ve been long
enough in this list to know who to ask if I want a long and thorough answer
;-) !! Thanks very much!
Ok, so obviously I didn´t remember every detail, but I knew it was something
along those lines.
I think that your approach is a good one and I will certainly have a go at
it! My requirements are infact also pretty view-centric so I think the
plugin idea is quite sufficient.
> commons-digester is supercalafragilisticexpealedociously cool.
Ok.... sounds good to me ;-) ! I will certainly give it a go. Now if there
is one thing I have learnt, then it is this: It´s just a matter of getting
your head down and learning the stuff! I don´t believe in something being
too hard (in terms of programming anyway :-) ), it´s just a question of
wether it makes sense or not. I remembered that you had mentioned doing
something similar and was hoping that you would share your experience - so,
thanks for that!

With the latest nightly builds (i.e. since 1.1b2) you actually *can* do
this. You have to set the servlet init parameter "validating" to false,
because otherwise your extended struts-config.xml file will not pass DTD
validation (which is on by default).
You'll still need to parse the struts-config.xml file yourself in order to
read the extra elements; the standard parse will simply ignore them.
Digester is useful for that.

See org.apache.struts.action.PlugIn for how you'll do your
initialization. There are several digester examples in the Struts
code-base. Look at the PlugIn implementations available in Struts and
then if you still have questions I can shoot you a skelleton. In fact,
I think I posted one to the list some time back. I've been intending to

commons-digester is supercalafragilisticexpealedociously cool. If
you're looking at adding some custom "thing" to Struts, I highly
recommend it. I can't imagine a simpler approach to making your
configuration declarative (versus programatic - ack - do you really want
to change code to change your config? Not me!) The rules you setup can
be a bit difficult to understand at first, but, with some requisite
amount of tinkering (doesn't take a lot) you'll figure it out fast. If
you do hit problems just yell.
Game Plan:
1 - Conceive an XML representation of the structure you wish to create
(structure = composition of objects - ApplicationConfig contains
ActionConfig etc).
2 - Generate a set of rules for digester that will do what you want with
the structure you've conceived.
3 - Write an implementation of the o.a.s.a.PlugIn interface that will
actually load things and put them into scope.
4 - Include your PlugIn implementation in your struts-config.xml
5 - Sit back and radiate pride for having built an add-on component that
can be included in each module.
Notes:
- *could* take one config file for the entire application
- *should* (probably) allow one config file per module (using a
scheme akin to what Struts does - or something else that guarantees
uniqueness)
- There's really no rule here - do what makes sense for *your*
application
My approach was to just programatically setup the rules in the PlugIn by
calling various digester.addXXX methods (you'll see). You can also use
plugable rulesets. For what I'm doing I just didn't see the advantage.
My stuff was pretty view-centric (and Struts-centric, at that), so I
don't really envision it ever being useful outside of Struts - or a
servlet container, for that matter.
If what you're doing is web-centric, but not Struts-centric, you may
wish to use a ContextListener instead of a PlugIn implementation. If
what you're doing requires some information from the Struts config (as
mine did), then you'll most certainly find a PlugIn implementation a
cleaner solution.
I did not provide a DTD for my XML config. You may wish to. Digester
supports this (though I can't speak to how easy it is to implement - my
guess is that part is easy too).
Good Luck! Yell back if you have problems.
