Re: [programmazione] Servlet Caching

[Luca Cicale]

Hi,
[EMAIL PROTECTED] is a static include, that is at compile time the compiled 
code
of the INCLUDED jsp is simply copied.
But if you change a included jsp/servlet after the INCLUDING page has been
compiled, well, nothing happens in the INCLUDING.
You have to touch (modify something) the including jsp to make it recompiled
with the included modified code.
An other option is to dinamically include the page using:

jsp:include

but it is really a different behaviour. Every time the including is called
it dinamically  recall the included one.

Regards
Luca Cicale

Hi there,

I am currently investigating a problem with our web app (Tomcat 5.5.23,
Java
1.5, JSF 1.2) where the servlet cache does not always get updated when a
JSF
include is changed. This happend after changing an included JSF. The
JSF-snippet that includes is:
html
[EMAIL PROTECTED] file=/pages/inc/head.inc%
f:view
[...]
body
[EMAIL PROTECTED] file=/pages/inc/bbs_header.inc%
h:form
[EMAIL PROTECTED] file=/pages/inc/menu.inc%
[...]

The JSPServlet config in web.xml:
   servlet
   servlet-namejsp/servlet-name
   servlet-classorg.apache.jasper.servlet.JspServlet/servlet-class
   init-param
   param-namefork/param-name
   param-valuefalse/param-value
   /init-param
   init-param
   param-namexpoweredBy/param-name
   param-valuefalse/param-value
   /init-param
   load-on-startup3/load-on-startup
   /servlet

Adding development=false and checkInterval=30 to the parameter list did
not
change anything.

Am I missing something or is there a limitation to the JSP Compiler with
checking the dependencies? Or is the problem based upon that [EMAIL PROTECTED] 
%
are not the way to include subviews in JSF?

If you want me to provide more infos, please tell me.

Thanks in advance for enlighten me,
Chris

Re: [programmazione] Servlet Caching

[Christian Poecher]

Thanks a bunch Luca. I inherited quite some messy code before the old
developer said goodbye. So far the big architectural issues in the Data
Access and Logic layers have been cleaned up, but the problems in the view
still exist. I will live with this issue for now and refactor the view later
to use JSF subviews instead of static includes.

Best regards,
Chris
