Can some one let me know is it possible to pass array or list to a log4j
appender property via log4j.xml or log4j.properties?

Something like below in appender I want to populate via log4j.xml or
log4j.properties

private List<String> validPackages;
public List<String> getValidPackages() {
        return buildVersionFile;}
public void setValidPackages(List<String> validPackages) {
        this.validPackages = validPackages}
