java.util.Enumeration mystr=request.getParameterNames();
int i;
try{
while(mystr.hasMoreElements()){
String e=mystr.nextElement().toString();
if(e.indexOf("group")==-1) {
String[] add=request.getParameterValues(e);
for(i=0;i<address.length;i++) myaddr.addaddr(add[i]);
}
}
}catch(Exception e){
System.err.println(e.getMessage());
