looping on a list of lists (or accessing custom attributes of a list)

Hi guys, here is my big problem today. I have a list the items of two kinds (with and without icons) which gets turned into a list of lists. [x , x, y, x,y, y, y, y,x, x,y] becomes [[x,x],[y],[x],[y,y,y,y],[x],[y]] When I render the list of lists in my JSP, I need to understand which kind

Re: looping on a list of lists (or accessing custom attributes of a list)

Martin Cooper wrote: Hmm... ;-) Two suggestions: 1) Instead of extending ArrayList, just encapsulate it. In other words, add a property to LinkWithIconList for the list, so that you can access the list explicitly using ${sub_list.list} or something. This seems like the simplest

Weblogic 9.0 and JSTL 1.1 ${variable} expansion

Hello, I'm involved in a distributed project. I develop a web app using Tomcat5, JSTL 1.1, Struts, Java 1.5 (but compiling for 1.4) and when I am done, someone somewhere else re-builds my app for Weblogic 9.0 and integrates with the back-end. Unfortunately, things are not going 100% smooth.

Re: Pagination source code

I asked a similar question a few months back. It appears that pagination is considered business-logic by some and view by others. Personally, I found that the following approach worked really well for me (it was a struts application): - I considered pagination part of the business logic - I

random numbers and JSTL

is there a JSTL trick to generate a random number? my problem is that I am desperate about disabling a cache and I need to make sure that a certain URL is perceived as different from a browser by adding stuff to the URL: href=http://url.do?d=c:out value=? / I could do this with a

JSTL, struts and pagination

people, what's the elegant way to do pagination with JSTL? I am using struts, my Action generates a LinkedList which a JSP page is supposed to visualize: c:forEach var=item items=${content_list} c:out value=${item.name}/br / /c:forEach I'd like the JSP to recognize long lists and

Hi there, here is my big problem today. I am using JSTL in some JSPs. SInce this is a struts project, I would like to keep my views totally separated from the Java APIs. For this reason, I need your advice about the most elegant to compare a given object type (an int constant) with the

Martin, Rahul thanks a lot to you both for answers in both threads. Very instructive. Unfortunately I have to support both versions of JSPs, so SimpleTag is out of question. I found a neat trick (used in another tag-lib) which prevented me to support two versions of my code while supporting

TagSupport vs BodyTagSupport

Hello, I would love to hear about some taglib theory here. My understanding is that, when creating a new tag, I can inherit from either TagSupport or BodyTagSupport depending on whether I need to manipulate the tag content or not. For this reason, most of my tags (WALL library) inherit from

Optimizing tag-lib performance

Hello again, I would like to improve the performance of a tag-lib I have created. Some obvious optimizations would be to turn things like: --- out.print( href=\+href+\); //title is optional if (!title.equals()) { out.print( title=\+title+\); } ---
