RE: TC4, does it reuse / pool custom tags?
TC can reuse tag instances (since TC 3.3 I think), but doesn't by default. Look for TagPoolManagerInterceptor / in server.xml to turn that feature on.

Re: TC4, does it reuse / pool custom tags?
Just to clarify, it's really Jasper that does the JSP compiling and determines whether or not custom tags get reused. There's not much difference, as I understand it, b/w the TC4 and TC3.x versions of Jasper. Here's a message Craig sent a while back (on the Struts list): = Yes. For example, Tomcat (more precisely, the Jasper component) does not currently recycle custom tag instances -- this is in the process of being addressed. Also, the code generator is very simplistic, does essentially no optimizations, and generates more code than it really needs to. This is not surprising, given Tomcat's heritage as being a reference implementation for the specs, rather than a high performance production environment. To the extent that people want to turn Tomcat into the latter, it will improve. = Donnie [EMAIL PROTECTED] 11/26/01 03:17PM Ulf == Ulf Dittmer [EMAIL PROTECTED] writes: Ulf TC can reuse tag instances (since TC 3.3 I think), but doesn't Ulf by default.

RE: TC4, does it reuse / pool custom tags?
This feature was added to Tomcat 3.3 after Tomcat 4.0 had branched off into its own develoment. I am not aware that these changes were ever ported to the Tomcat 4.x branch. This feature hasn't received a lot of testing, so you will need to do your own to insure it is working properly for your application.

Hello, I was wondering if TC4 ever reuses instances of custom tags. It looks like I get a new instance each time. At the moment, it does not reuse custom tag instances. There is some work going on to improve the overall performance of the code generated for JSP pages, and this is one of the areas being investigated. -- Peter Mutsaers | Dübendorf| UNIX - Live free or die [EMAIL PROTECTED] | Switzerland | Sent via FreeBSD 4.4-stable Craig -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]
