Slide logging, usage of servlet filters and Servlet_23 requiremen t

["Nevermann, Dr., Peter" <Pe...@softwareag.com>]

Hi,

I'm planning to remove logging from the Slide servlet (mainly coded in the
service() method of org.apache.slide.webdav.WebdavServlet.java) and provide
adecuate servlet filters instead.

The first filter (which is already running on my PC :) ) would be
org.apache.slide.webdav.filter.LogFilter.java which would log one line per
request. It wouldn't make use of Log4J. By means of init-param's in web.xml
(where the filters have to be installed) the following could be configured:

a) logFormat (e.g. 
   "[%t], [%p], %m, %s \"%l\", %i, %u"
   where t=thread, p=principal, m=method, s=status, l=long-message,
i=time-elapsed, u=uri
   would yield log lines of the form
   [Thread-4], [localhost/xdav], CHECKOUT, 405 "Method Not Allowed", 156 ms,
/mycoll/a.xml)

b) output (e.g. console, servlet log file, custom file)

Another filter would replace the detailed XML-based request/response logging
once added by Hardy Kiefer.

Maybe there are ideas for more useful filters to deliver with Slide?

Comments, suggestions, objections?


Also, I would like make Servlet 2.3 a prerequisite for Slide 2.0. We could
remove the servlet22/servlet23 handling from build.xml and get rid of the
nasty (not compiling) sources named *22.java, *23.java. So, it would mean
that Slide 2.0 requires Tomcat 4.x.

Comments, suggestions, objections?

Thanks,
Peter

This would be cleaner as it is now : Log code would be pluggable.

Tomcat 4.x seems to be quite stable now and has much better performances
than older so I think it is not a big problem to make it a prerequisite,
considering that only few people seems to use Tomcat 3.x.
But are latest stable versions of other servlet containers (JBoss,
Weblogic) implementing Servlet API 2.3 ?
