Hi, I'm running Tomcat 5.5 under Eclipse 3.5. I want to see some access logging because for instance it silently ignores imported style sheets it can't find. I saw a reference somewhere to org.apache.catalina.valves.AccessLogValve so I tried uncommenting that in server.xml but it makes no difference. Nothing extra to the console, nothing to any log file in the workspace.

This is all I get in the console window:

    Created MBeanServer with ID: 635da44f:126e1e2f13c:-8000:Dylan:1

As a quick test, I tried uncommenting the AccessLogValve with Tomcat
5.5.28 and it worked for me. Note that the server.xml you need to
modify is the one under the appropriate subfolder of the Servers project
in your workspace. Even though the comment in server.xml says the
"logs" directory is relative to CATALINA_HOME, it is really relative to
CATALINA_BASE, which is how it should work. The CATALINA_BASE (actually
the catalina.base system property in the launch configuration) defaults
to
"<your_workspace>/.metadata/.plugins/org.eclipse.wst.server.core/tmp? "
when a new Tomcat server is created. Make sure you that is where you
are looking for the "logs" directory if you haven't changed the server
configuration from the default.

Though unrelated to seeing the AccessLogValve output, to configure JULI
logging, see:

http://wiki.eclipse.org/WTP_Tomcat_FAQ#How_do_I_enable_the_J ULI_logging_in_a_Tomcat_5.5_Server_instance.3F

Cheers,

Hi, thanks. I figured it out in the end. Like you say for a fresh project that works. What I did though was make the server.xml change after a few server start/restart iterations. What I had to do to fix it - which I think I found on the web somewhere - was right click on the server in the bottom pane and then do "Clean...". Odd really because you make a change to a servlet and it Just Works but make a change to server.xml and it's very obscure...

If it helps in the future, for "Clean..." to fix the behavior suggests
that something went wrong with the "delta" publishing. The "delta"
publishing that the Tomcat support uses relies on a cache of data
storing the files and their dates for what has been included in past
publishes. If during publishing, the project file to be published is
found in the cache and it's date hasn't changed, then that file is not
published again. If that file, for some unknown reason, is no longer
present in the published webapp, "delta" publishing won't make it
reappear. Using "Clean..." deletes this cache and forces a full
publish, fixing any such disappearances. So far, I haven't identified
any usage scenario, other than deliberately deleting the webapp's file,
that would account for the mysterious disappearance of published files.
Let us know if you happen to find one.

Cheers,
Larry
