You can set VM argument : -Dlog4j.configuration='path_to_log4j.xml'

or programatically :

String logFilePath = new File();
if (logFilePath == null || "".equalsIgnoreCase(logFilePath)) {
    URL file = this.getClass().getResource(DEFAULT_CONF);
    DOMConfigurator.configure(file);
} else {
    DOMConfigurator.configure();   
}
