No puedo utilizar la funcion String.replaceAll, una funcion similiar??

[kreutz]

public String replaceString(String source, String p0, String p1) {
String result = source;
int p = 0;
while ((p=result.replaceAll(p0,p1).indexOf(p0, p))>-1){
result=result.substring(0,p)+p1+result.substring(p +p0.length());
p=p+p1.length();
}
return result;
}
