Java util logging.properties: How to connect to two different files

I place logging.properties in the WEB-INF / classes tomcat directory

I would like to register in two different files. For example: org.pkg1 goes to one file, and org.pkg2 goes to a separate file.

I can configure one file, but not two. Is it possible?

I finally figured it out. In tomcat, they extend the java util ("JULI") protocols to enable this feature. Here is the logging.properties file that I entered in the WEB-INF directory, which finally completed what happened after ......:

handlers=1console.java.util.logging.ConsoleHandler, 2jsp.org.apache.juli.FileHandler, 3financials.org.apache.juli.FileHandler
.handlers=1a.java.util.logging.ConsoleHandler

jsp.level=ALL
jsp.handlers=2jsp.org.apache.juli.FileHandler
org.apache.jasper.level = FINE
org.apache.jasper.handlers=2jsp.org.apache.juli.FileHandler
org.apache.jsp.level = FINE
org.apache.jsp.handlers=2jsp.org.apache.juli.FileHandler

com.paypal.level=ALL

3financials.org.apache.juli.FileHandler.level=ALL
3financials.org.apache.juli.FileHandler.directory=${catalina.base}/logs
3financials.org.apache.juli.FileHandler.prefix=financials.

2jsp.org.apache.juli.FileHandler.level=ALL
2jsp.org.apache.juli.FileHandler.directory=${catalina.base}/logs
