[Q] Performance of SQL tags?

Is the SQL tags (in JSTL) performance acceptable? I'm populating tables and was wondering if it would be better to read the data in normal Java code and then populate the table with td%= row.getItem1() %/td td%= row.getItem2() %/td etc. I'm not too worried about trying to keep java code out

RE: taglibs i/o or jstl core library

thanks, i tried this on opera 6 for windows and it does not compute the base URI of the document per Section 14.14 of rfc2616. i tried using the jstl redirect tag but the app doesn't recognise it the header returns a blank and whats within the body tags takes up the space. it looks like a

Re: [Q] Performance of SQL tags?

Just guessing, but I doubt it will be faster performance-wise, just faster to develop. It lets you treat JSP as a scripting language and remove the compile/deploy stage. Hen On Thu, 5 Feb 2004, Riaan Oberholzer wrote: Is the SQL tags (in JSTL) performance acceptable? I'm populating tables

RE: taglibs i/o or jstl core library

yes. i have an application with an include header.jsp file, and its using the c:redirect/ tag to go to the remote site then nothing happens in terms of header.jsp tag, this is missing from the browser page and appears to return nothing. in terms of the c:import tag it works ok if the url is

Re: [Q] Performance of SQL tags?

When you're talking about read the data, what type of object would you be reading from? If it's a Result generated by one of the tags, then any significant performance hit will already have been taken. In other words, the *potentially* slow and memory intensive part of the SQL tags is in

EL not being evaluated?

I've installed JDK 1.4.2_03, Tomcat 5.0.18 and Apache's JSTL 1.1 on RH Linux 9. My XHTML JSP contains a simple construct: p1 + 2 + 3 = c:out value=${1+2+3}//p But the expression is not being evaluated, yet the c:out tag is being processed fine. The output just looks like: 1 + 2 + 3 =

RE: how to use methods with parameters

There a several different ways to calculate days, based on the definition of day; e.g. should 23:59 - 00:01 count as a day? Nevertheless, once you decide on those rules, you can write your own custom tag (I don't believe JSTL has such a function). my:days start=%= startDate % end=%= endDate % /

Re: how to use methods with parameters

Depends. If you're using a JSP 2.0 container, you can create EL functions that map to public static Java methods. See section 2.6 of the JSP 2.0 Spec. JSTL 1.1 provides a basic set of EL functions, see section 15 of the JSTL 1.1 Spec. However, if you're using JSTL 1.0 (JSP 1.2), then you're kind

RE: EL not being evaluated?

el has been incorporated into JSP 2.0 which is what Tomcat 5 implements. So, you no longer need the c:out tag. Just do: p1 + 2 + 3 = ${1+2+3}/p Check out Tomcat's default pages to see more cool things you can do with Tomcat 5 (JSP 2.0/Servlet2.4). -Ben From: David Wall [EMAIL PROTECTED]

Since you're using a JSP 2.0 container, you should be able to just do: p1 + 2 + 3 = ${1+2+3}/p Make sure you're using a Servlet 2.4 deployment descriptor. That didn't work for me. Perhaps it's your last comment. What does it mean to have a 2.4 deployment descriptor for the JSP page? Maybe

Re: EL not being evaluated?

I think you need to indicate in the web.xml that this is a jsp version 2 web application, otherwise the container assumes the web application is written for an old jsp version where not the container but the taglib does the EL evaluation (you would need the 1.0.5 taglib version for this).

AW: how to use methods with parameters

thanks to you all. Unfortunately I am stuck to JSTL 1.0 since I use Tomcat 4 with JSP 1.2. I am aware now that JSP 2.0 offers a lot improvements. However, I do not feel very comfortable with the idea to setup static methods for each el function. I am also very interested in the technical aspects:

Re: [Q]i18n

Section 8.3 of the JSTL 1.0 Spec provides the details of how a basename and set of preferred locales are used to determine the resource bundle. Give it a look and post back if you still have questions. You should notice that the set of preferred locales can either be taken from the client/browser
