使用Weblogic JMS监控log4j的日志
配置CLASSPATH下的log4j.properties:# This is the configuring for logging displayed in the Application Server;delete ,stdout
log4j.rootCategory=INFO,R,A1
log4j.appender.A1=org.apache.log4j.net.JMSAppender
log4j.appender.A1.providerURL=t3://localhost:7001
#log4j.appender.A1.userName=weblogic
#log4j.appender.A1.password=weblogic
log4j.appender.A1.topicConnectionFactoryBindingName=jms/JNDI_JMS_Connection_Factory
log4j.appender.A1.topicBindingName=jms/JNDI_LOG_TOPIC
log4j.appender.A1.initialContextFactoryName=weblogic.jndi.WLInitialContextFactory
注意：
1,应该是消息主题（TOPIC），下面的配置和代码也应该为topic，而不是queue
2,Log4j的版本是log4j-1.2.15.jar，并且应该将log4j-1.2.15.jar拷贝到%WL_HOME%\user_projects\domains\base_domain\lib下。
