Struts bean:define to JSTL EL
Hi all. I'm new at JSTL, I hope someone can help me here. I have struts bean:define which looks like this: bean:define name=UIManager property=collection(tab) / UIManager bean has getCollection(String) property. What is the equivalent syntax for JSTL? Thanx.

Are you trying to do an entry form that stores the data in the db? Please
clarify.
As for Struts: I am not familiar with those. I am actually not that
familiar with JSP itself. That is why i decided to start with JSTL (it
makes things easier). Sorry.

You can pass the value from your search form to the page which you
have
listed in your email. For example: You have a search form with a
text
box
titled search
Here's what the page that queries the db would look like now
sql:query var=productQuery dataSource=${productDS}
SELECT * FROM CD WHERE CDTITLE = ?
sql:param value=${param.search}/
/sql:query
You can also expand on this by using the OR statement in your query.
For
example:
sql:query var=productQuery dataSource=${productDS}
SELECT * FROM CD WHERE CDTITLE = ? OR ARTIST = ?
sql:param value=${param.search}/
sql:param value=${param.search}/
/sql:query
For every condition in your query you must add a sql;param/ tag.
Hope this helps. I really do recomend that you get Shawn Bayern's
book
titled JSTL in Action. It explains all this in great detail, plus
everything else.

Re: Tag List
Thanks I will look at Maverick. Why is Maverick and Struts considerd MVC,
when the idea of JSP is part of MVC?

Yes, if you're using JSTL then you will be a whole lot better off with
an MVC framework like Struts or Maverick. I recommend Maverick - it's
considerably simpler than Struts, yet offers more features. Also,
unlike most other similar frameworks (Struts, WebWork, etc), Maverick
never started out with a now-crufty set of specialized set of JSP tags -
JSTL works great.
The core distribution includes a sample application that uses JSTL.

Re: Tag List
Scott,
Is this kinda what you mean? Are you trying to add the
search/edit/remove/add functionality to the jsp page? This could easily
be captured with forms which submit back to the jsp plus a choose block
to designate which operation is being performed. I bet this'll really
irk those Struts/Maveric MVC folks out there with its use of the JSP
page as both the Controller and View. But it is relatively easy to
accomplish using JSTL without such heavy MVC frameworks.
Here is the example:
%@page contentType=text/html%
%@ taglib prefix=c uri=http://java.sun.com/jstl/core; %
%@ taglib prefix=sql uri=http://java.sun.com/jstl/sql; %
sql:setDataSource var=productDS
url=jdbc:postgresql://localhost:5432/recruitment
driver=org.postgresql.Driver
user=scott password= /

c:when test=${request.operation == 'Add'}
sql:update... sql tags to support the add request
/c:when
c:when test=${request.operation == 'Remove'}
sql:update... sql tags to support the remove request
/c:when
c:when test=${request.operation == 'Edit'}
sql:update... sql tags to support the edit request
/c:when
/c:choose
%-- query to load the html page contents --%

%-- EXPAND YOUR QUERY WITH SEARCH TERMS HERE --%

If you want to encapsulate the functions for adding/removing/editing
the content and not have them in this View/Controller, you could
include them from separate JSP's or Servlets. or likewise submit the
forms directly to those JSP's or Servlets and then redirect back to
this jsp once the work was done.
It stays pretty independent and light without too much dependency on
any particular framework other than the JSP/JSTL tags. Which results in
less research and development effort to accomplish the same task. All
you need to know is JSP/JSTL.

Re: EL Functions
From what little I know, JSP 2.0 introduces the concept of functions to EL. I doubt these equate to ECMAScript, but is rather the ability to define your own functions.

Re: EL Functions
JSP 2.0 provides tag-library developers with the ability to expose static methods as functions in their TLDs. These functions will be accessible to authors of any pages that import the containing tag library. This facility also allows JSTL to expose a set of standard functions. The precise set of functions that JSTL 1.1 will expose is still being debated, but it will likely include a limited set of string-manipulation functions and a handful of targeted solutions (such as a 'size' function). Future versions of JSTL can expose more functions as necessary. -- Shawn Bayern JSTL in Action http://www.manning.com/bayern On Sun, 16 Feb 2003, Henri Yandell wrote: From what little I know, JSP 2.0 introduces the concept of functions to EL.
