XSP tag-libs reload
Is there any way to develop and debug a library of logic tags (XSL with XSP
tags) without deleting the XSP repository and reseting cocoon?
This issue is only a little inconvenient, but think in changing a tag-lib in
a production environment with JServ in automatic mode (controlled by Apache).
Perhaps I'm in a big mistake, but by now I must kill the Jserv process.
Other big problem: the stability of the system with big loads. Try to put a
apache bench (ab) or a JMeter with 10 threads, and simultaneously do a
request from your browser. The application of the XSL isn't correct.
This is a great product, let's work to make it better... :)
Thanks in advance.
Rober
BTW, I'm curious on real experiences in production environments with Cocoon,
like http://www.exoffice.org, I think I must ask in another forum... ;)

Maybe you have two references to one class repository.
I had the same problem because I got two equal classpath entries : one in the
jserv.properties and other in the servlet-zone conf file.

I can't achieve the expected behaviour.
I must delete the repository an reset Jserv.
Can someone send me a working configuration (servlet-zone file,
cocoon.properties file, xsp taglib and xml file) with dynamic taglib
reload?
Thanks in advance.

Cocoon1 doesn't work well under heavy load because of memory issues. No
secrets about it.
But Cocoon2 will make a difference.

Mostly touching the XML file helps with reloading associated XSP files,
but XSL files only reload when restarting cocoon.
