Re: JSTL Question
David:
The 'field'(s) are defined in RestaurantBean.java if they're not there
nothing happens. cuisine and city field's are exact matches. The name
field is user input and is case insensitive and will any partial part of
a matching name.
What I want to do is to have param.field or ${restaurant[param.field]}
evaluated only once at the beginning of the table. param.field only
needs to be evaluated once as it becomes the name of the table.
Thanks,
Jack

It's a little hard to tell exactly what you're trying to do here, but it
might be helpful to know that '${restaurant.cuisine}' is the same as
'${restaurant[param.field]}' if param.field is equal to cuisine.
With this, you would need only the single case. This strategy is only
useful if you really can guarantee that you know all the possible values
of param.field. If you can't be certain, then this could produce
unexpected problems down the road.

Subject: JSTL Question
I have the following 'working' code to produce a table. The value of
${param.field} determines which field will be displayed in column 3.
Can I move this out of the c:forEach loop and assign a temp
variable to
it using c:if/c:set so that I only need to evaluate the value of
${param.field} once and not on every line? ${param.field}
will always
equal city, cuisine or name.

That way you don't need access to a ServletContext instance.

JSTL - c:if test Question
I am using the following line of code to test strings for equailty.
In most cases I'm just trying to compare a city name in an array to
user input for the name of a city i.e. Seattle.
c:if test=${restaurant.filterValue eq param.value}
If the user enters seattle instead of Seattle I don't get a response.
Is there a way to alter this statement to make it case insensitive?
Is there a way to alter it to respond like a SQL %LIKE% query?

Re: Custom Taglib /JSTL 1.1.2/JBoss4.0.1 Problem - Unparseable date
This code worked just fine under JSTL 1.0.x and JBoss3.0.x/3.2.x.
When I moved it to and about a dozen other tags to JSTL 1.1x I just
chaned the DD to allow RT. The error seem to be from:
org.jboss.util.propertyeditor.DateEditor.getValue(DateEditor.java:42)
For some reason the JBoss DateEditor is overriding java.util.Date and
java.text.SimpleDateFormat.
The properties-service.xml is supposed to be able to set a default
DateParser but none of the combinations I've tried ahas worked. Is
there a specific DateParser in the JSTL package that you know of? I
haven't been able to find one.
Apparently something like this is supposed to be used. Anyone have any
ideas on what to do here?
Thanks,
Jack

It seems to affect any call to java.util.Date in a jsp page. The exception is
coming from a custom tag library that I use for scheduling when date/time
sensitive persistant content should be displayed. This code works fine in
v3.0.7, v3.2.7 but not in v4.0.1. I tried several different combinations in
the 'properties-service.xml' file, all of which generated mbean errors.
I don't have a clue as to what should be used here. Is the a way to disable
the default date parser?
Any help would be appreciated.

JSTL/JSP/regexp Question
I'm using the following code to return results from drop down menues and
user input text.
It works fine as long as the text is an exact case sensitive match to
the data record.
What I want to do is evaluate the output the results of a user input
search based on
'param.field' in figure 3. i.e. If 'param.field' = 'name' use a regex
or some other method
to return all records that are a partial, case insensitive match to the
input 'value' that
was submitted in the search request. Is this possible to accomplish in
JSTL? If so I'd
like to know how.
Thanks,
Jack

JSTL Formatting Question
I'm using the following jsp page to display tide tables. How can I
separate the days using the retrieved date field so the date only
appears on the first line of the result set and only appears again when
the date changes. There are usually 6-7 lines of data for each day.
I'd like to achieve something that looks like this:
2004-05-08 2:57AM 7.27 feet Low Tide
5:38AM Sunrise
6:44AM 8.45 feet High Tide
2:43PM -2.81 feet Low Tide
8:37PM Sunset
10:55 PM 9.98 feet High Tide
2004-05-09 4:13AM 7.28 feet Low Tide
5:36AM Sunrise
The page can be seen here:

TDL problem

The attrib 'amount' comes from a session variable holds the total purchase amout. I'm not sure what else to try. Any suggestions would be appreciated.

Re: TDL problem
I tried all theses, just forget to put that in my origianl message.
The problem seems to be that what the error says:
According to TLD or attribute directive in tag file,
attribute amount does not accept any expressions
If if use a hard coded value for 'amount' i.e. 75.00 it works.
If I use the existing value of ${grandTotal} it causes the error.
I don't know what changed between the versions that would cause
this to happen.
Any suggestions?

Assuming you've actually got the JSTL 1.1 JAR files in WEB-INF/lib, the next
thing to verify is your taglib URIs. They've changed from 1.0 to 1.1:
1.0
%@ taglib prefix=c uri=http://java.sun.com/jstl/core; %
1.1
%@ taglib prefix=c uri=http://java.sun.com/jsp/jstl/core; %
Just to add something new to this FAQ, I've gotten in the habit of creating a
file called taglib.jspf that contains:
%@ taglib prefix=c uri=http://java.sun.com/jstl/core; %
%@ taglib prefix=fmt uri=http://java.sun.com/jstl/fmt; %
%@ taglib prefix=sql uri=http://java.sun.com/jstl/sql; %
%@ taglib prefix=x uri=http://java.sun.com/jstl/xml; %
%-- plus other taglib directives --%
And my JSPs contain:
%@ include file=taglib.jspf %
So, if I need to change something, like, oh, the URI to move from JSTL 1.0 to
1.1, I only have to change one file. YMMV...

SQL / Date query
I'm trying to create a JSP page the will display rows of a table beginning on the current date and ending at a total of 7 days. The following query works in MySQL but returns the following error when attempting to run the jsp: org.apache.jasper.JasperException: SELECT date, time, am_pm, height, cond FROM cherry_point_tides WHERE date BETWEEN CURDATE and CURDATE() + INTERVAL 6 DAY : Column not found, message from server: Unknown column 'CURDATE' in 'where clause' at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:254) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:295) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:241) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Formatting question
Is it possible to create a jsp template with two or maybe three tables containing three fields each and populate them from a SQL query with am maximum depth of 30 lines in successive order? i.e. populate the first table with 30 lines then populate the second table with the next 30 lines starting with the 31st result, etc. I've seen this done but I'm not sure how to go about it.
