If one wants to have the conf\logging.properties read one must (see also here) dump this file into the Servers\Tomcat v7.0 Server at localhost-config\ folder and then add the lines :
-Djava.util.logging.config.file=”${workspace_loc}\Servers\Tomcat v7.0 Server at localhost-config\logging.properties” -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
to the VM arguments of the launch configuration one is using.
This may have taken a restart or two (or not) but finally I saw in the console in bright red :
FINE: No TLD files were found in [file:/C:/Dropbox/eclipse_workspaces/javaEE/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/ted2012/WEB-INF/lib/logback-classic-1.0.7.jar]. Consider adding the JAR to the tomcat.util.scan.DefaultJarScanner.jarsToSkip or org.apache.catalina.startup.TldConfig.jarsToSkip property in CATALINA_BASE/conf/catalina.properties file. //etc
I still don’t know when exactly this EDIT: from the comment by @Stephan: “The FINE warning appears each time any change is done in the JSP file”.FINE warning appears – does not appear immediately on tomcat launch
Bonus: To make the warning go away add in catalina.properties :
# Additional JARs (over and above the default JARs listed above) to skip when
# scanning for TLDs. The list must be a comma separated list of JAR file names.
org.apache.catalina.startup.TldConfig.jarsToSkip=logback-classic-1.0.7.jar,\
joda-time-2.1.jar,joda-time-2.1-javadoc.jar,mysql-connector-java-5.1.24-bin.jar,\
logback-core-1.0.7.jar,javax.servlet.jsp.jstl-api-1.2.1.jar
