Resolution
To configure logging for an application, you should edit needed Host/Context section in server.xml to add Logger:
<Logger className="org.apache.catalina.logger.FileLogger" prefix="domain.com_examples_log." suffix=".txt" timestamp="true"/>
For example logging directived for the examples application on domain.com should looks like:
<Host name="domain.com" debug="0" appBase="webapps" unpackWARs="true">
<Context path="/examples" docBase="examples" debug="0" reloadable="true">
<Logger className="org.apache.catalina.logger.FileLogger" prefix="domain.com_examples_log." suffix=".txt" timestamp="true"/>
</Context>
</Host>
After that, "examples" application for "domain.com" will write log into "domain.com_examples_log.*" files.
