<param name="File" value="C:\\logs\\cle_error.log" />

My server name is App_Admin and path where i want to generate debug.log file is /waslib/appadmin/uat/logs.

Answer 1

You could use System property for this like:

<param name="File" value="${mylog.path}" />

And when you start your application, you could just pass system property like:

java -Dmylog.path="/waslib/appadmin/uat/logs" ...
