Hi
Thanks for the reply, so just let me know if i understood it correctly
in myfirstwebapp i will have log4j.xml file as
<param name="File"
value="${myfirstwebapp}\\log4jXmlFilter.log" />
and in context listener i will set System.setProperty("myfirstwebapp",
rootpath);
and in mysecondwebapp i will have log4j.xml file as
<param name="File"
value="${mysecondwebapp}\\log4jXmlFilter.log" />
and in context listener i will set System.setProperty("mysecondwebapp",
rootpath);
does this look good
