Subject Re: tomcat 6.0.18 clustering.. session getting replicated partially
Date Tue, 25 Nov 2008 16:14:38 GMT
Hi Filip,

   All I did was to modify sessions application that comes with tomcat. It's
just two simple changes shown below.

   1) Replace the DummCart.class in
<tomcat-home>\apache-tomcat-6.0.18\webapps\examples\WEB-INF\classes\sessions
with the attached one.
   2)mark the web.xml in
<tomcat-home>\apache-tomcat-6.0.18\webapps\examples\WEB-INF as distributable
by adding </distributable> tag
   3)then access this by using
https://localhost/examples/jsp/sessions/carts.jsp

Please let me know...Thanks for doing this
Rohit
