Answer 1

you have to define a new appender:

<appender name="jasper" class="org.apache.log4j.RollingFileAppender">
    <param name="append" value="true" />
    <param name="maxFileSize" value="10MB" />
    <param name="maxBackupIndex" value="10" />
    <param name="file" value="${catalina.home}/logs/jasperReports.log" />
    <layout class="org.apache.log4j.PatternLayout">
    <param name="ConversionPattern" value="[%d{dd-MM-yyyy HH:mm:ss}] [%c{1}] %-5p:%L - %m%n" />
    </layout>
</appender>

And a new category with have the apender as reference:

<category additivity="false"  name="net.sf.jasperreports">
    <priority value="debug" />
    <appender-ref ref="jasper"/>
</category>
