Memo: log4j in tomcat (备忘:Tomcat中配置log4j)

March 9th, 2015

In a tomcat project, we can configure log4j to write logs in a file with:
This will put all the log files in the /log dir under tomcat root dir.

Here is a full version of the sample

### direct log messages to stdout ###
# log message format: 10:48:40,399 INFO Test:36 - [3, 2, 1]
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
### direct log messages to file ###
log4j.appender.rollingFile.layout = org.apache.log4j.PatternLayout
# log message format: INFO main wp.newsbag.Test - message ...
#log4j.appender.rollingFile.layout.ConversionPattern=%p %t %c - %m%n
log4j.appender.rollingFile.layout.ConversionPattern=%d{dd MMM yyyy HH:mm:ss,SSS} %5p %c:%L - %m%n
#log4j.rootLogger=debug, stdout
log4j.rootLogger=debug, rollingFile

Location of tomcat work dir in eclipse (Eclipse中tomcat工作目录)

March 9th, 2015

The default dir for eclipse to publish we apps in tomcat is WORKSPACE\.metadata\.plugins\org.eclipse.wst.server.core\tmpX, where X could be 0, 1, 2, depending on how servers you have configured. Of course, the dir can be changed as shown in the Server project, as shown in the pic below:

备忘:Eclipse中tomcat的默认工作目录为:WORKSPACE\.metadata\.plugins\org.eclipse.wst.server.core\tmpX,X可能为0,1,2….。当然,这个目录可以在Server Project中修改,如上图所示。

Here are some common used configurations of tomcat.

  • Add a new tomcat host. In server.xml, add these lines:
    		<Host name="" appBase="/var/www/domain_webapps_dir"
                    unpackWARs="true" autoDeploy="false">
                    <Context path="" docBase="/var/www/domain_webapps_dir/proect_name" reloadable="true" />
                    <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
                            prefix="xxx_access_log." suffix=".txt"
