Hello all,
 
Disclaimer: I'm relatively new to the Java platform, so, please forgive
me if I am making any obvious rookie mistakes.  
 
Summary: I am working with dnsjava to write some classes to replace our
DDNS PERL libraries (NET::DNS).  I can successfully connect to my
nameservers, run queries, extract zone transfers, and even add "A
Records", however, I am having trouble adding an MX record to a zone.  
 
1)  Here is a snippet of the code I am using to add an A record (that
works):
 
                Name Nzone         = Name.fromString(zone);
                Name Nhost         = Name.fromString(host, Nzone);
 
                Update update      = new Update(Nzone);
                //System.out.println("Update: " + Nhost + " " +
typeValue + " " + ttl + " " + ip);
                
                Record r = Record.newRecord(Nhost, typeValue, dclass); 
 
                update.add(Nhost, typeValue, ttl, ip);
                
                Resolver res       = new SimpleResolver(this.master);
                                     res.setTSIGKey(this.keyName,
this.keyValue);
                                     res.setTCP(true);
                     
                Message msg = res.send(update);
                
                if (doesRecordExist(r, res))
                    return true;                          
 
2)  Here is the snippet of code based on the above that tried to adapt
to add MX records (does not work yet):
 
                Name Nzone         = Name.fromString(zone);
                Name Nhost         =
Name.fromString(Nfqdn.getLabelString(0), Nzone);
 
                MXRecord m         = new MXRecord(Nfqdn, dclass, ttl,
pref, Ntarget);
                
                System.out.println("m: " + m.toString());
                
                Update update      = new Update(Nzone);
                //System.out.println("Update: " + Nhost + " " +
typeValue + " " + ttl + " " + ip);
                
                Record r = (Record) m; 
                
                System.out.println("r: " + r.toString());
 
                update.add(r);  //I've tried both update.add(r) and
update.add(m)
                
                Resolver res       = new SimpleResolver(this.master);
                                     res.setTSIGKey(this.keyName,
this.keyValue);
                                     res.setTCP(true);
                     
                Message msg = res.send(update);
                
                if (doesRecordExist(r, res))
                    return true;                            
 
 
 
3)  When i call the toString() method of my MX record objects, they do
appear to be correct:
 
m: wwwwww.zzogy.com.    3600    ANY     MX      10 mail.yahooo.com.
r:   wwwwww.zzogy.com.    3600    ANY     MX      10 mail.yahooo.com.

(these are just tests)
 
 
Thanks in advance for any assistance/pointers you can offer.
 
I have programmed mostly PERL for the last 10 years or so, but I am
really liking Java.  It's much cleaner and organized.
