customized log4j.property location by adding system property

I put log4j.properties in classpath, but it is not located classpath root directory. I put all properties into properties directory to keep root classpath organized clean structure. Since I moved the log4j.properties file, log4j makes error when process start up. I had to put below line which add system property.
-Dlog4j.configuration="properties/log4j.properties" then it works well now.
