我如何使用log4j.xml在stuts2中创建日志文件，并为不同级别和不同的Web项目创建单独的日志文件

Question

i have tried to built something but it stores the data in a single file and only when server starts and i pass some argument.

the file created is same like the server.log file. there is one more thing is I'm using jboss server . and the xml file is placed under /home/stpl/Desktop/jboss-4.2.2.GA_new/server/default/conf folder . .

here is my xml:

<?xml version="1.0" encoding="UTF-8"?>

Answer 1

i have done this by writing the log configuration in server.log file inside jboss/server/conf folder.

The log file are separated by there levels. Following is my xml code:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<!-- ===================================================================== -->
<!--                                                                       -->
<!--  Log4j Configuration                                                  -->
<!--                                                                       -->
