Re: Custom tag question
The first thing this makes me think of is why don't you just use an iterate
tag over the bean tag. Can you say more about what you are trying to accomplish?

Custom tag question
Hi,
I have a question pertaining intregrating a custom tags with a struts
tag. I want to know if there exists a "best practise" when trying to do
what I'm doing (other than not doing it).
I am trying to write a custom tag which wraps another tag in the
following way:
HTML Written:
Desired Output: "printout" number of tags
Code to do it:
--
void doStartTag() ... {
...
for(int i=0 ; iHave you guys come across a situation where you had to do something like
this? and if so, what is the best way of creating such a custom tag?
Would you use a .tag to produce the effect described above?
Thanks.
Aladin

POSSIBLE OT: localised hashtable custom tag question
Ok here's the scenario
My (opensource) application is going to be available in the users
language.
All my struts localisation stuff is working fine, all the labels and
stuff are stored in property files etc.
I am using hibernate for persistance.
JSTL does not allow you to call functions on objects.
It only allows you to access the properties of beans. ie you cannot
do ${object.getDesctription("fr")}
One of my hibernate POJO's house has got a hash of descriptions inside it.
The descriptions are going to be referenced by java.util.Locale objects
The reason is so that the description of the house itself is going to be
localised.
--
So what I want to do is either create or use a tag which will allow me
to do the
following.
or
The tag will then access the struts session and see what Locale the
person is
using.
If there is a description that matches that locale it will be outputted ,
if not the description matching the default locale will be used.
Perhaps I am looking in completely the wrong direction.
If I am being stupid here please feel free to alert me
I've been trying to decide the best approach for about 2 weeks.
I don't really think this belongs in the DAO or hibernate layers
as it is kinda a presentation issue.
Is anyone else working with something similar ? Or do I have to
build up a tag lib from scratch ?
Thanks
Bryan

In your "B" caes you're trying to nest double quotes inside double
quotes, which is not valid syntax. change the outer set to single
quotes and this should work fine.

Thanks again!,

Subject: Re: OFF-TOPIC - Paging Results
A question that I wondered for long. AFAIK, there are 2 paging policies:
- paging in app server memory, in session scope to enable paging in
clustered environments, or
- paging in dababase, using scrollable resulsets or related.
I guess, paging in app server, can overload server memory if query results
are long, so database paging should be better, in such a cases. However, I
do not know if state of arts in database paging is technologically ready.
I would appreciate comments further on this first impressions.
Regards,
Adolfo.

Hello!
Sorry for the off-topic message.
I would like to know if you recommend any good component for paging
results
and presenting it in a JSP page. I'm using struts, so if you know a
component that integrates well with struts, that's perfect.
Thanks for your help.
For working directly with Struts, Matt Raible's display tag is quite
popular.
http://displaytag.sourceforge.net
If you are using the JavaServer Faces integration library with Struts, the
standard component handles paging quite nicely. In addition,
it lets you do input fields in the table, not just output.
