O.k., I figured it out - stupid mistake on my part :roll: - thanks for the hint Kalichar, it helped.
Jeff
Yes, please share what the problem was - I'm having the same thing happen. I can connect once with a client, but once I kill the client I have to restart the server to connect again.
Thanks,
Jeff
Probably not. As I understand it there are 2 versions of the FBN assignment - one where you are supplied a text file and you need to write a conversion routine to generate a binary file and one where the binary file is supplied. I have the first one and had to write the conversion program. In doing so, the field names are not specified and I could call them whatever I wanted, so that's why I think the example from Sun is just a guideline as far as the exact field names.

Rudy,
I think the Sun example was just that - an example. In my assignment (where we have to do a data conversion utility), the specific field names are specified by the developer anyway. Sam is correct in that the spec says when "an invalid field name being provided as part of the criteria the behavior of this method is the same as if no records matching correctly specified criteria" were found. Not sure about your "message" approach in that case, since if no records are found I would just return a null array not any type of message.
Jeff
I don't think this is a problem, since delete() doesn't actually remove the record, it just sets the record's attribute to DELETED_RECORD, so the record numbers will not change.

I did the data conversion utility generically, so you could specify the column names, sizes, etc. and generate a binary file. What I'm struggling with now is how best to inject some specifics into the database after the binary file is read. For example, if you wanted to reserve some seats on a flight, you would need to know which column contained the seat information. Likewise, to search for flights originating from a particular airport, you would need the originating airport column name (or you could derive it from the column number I suppose) for criteriaFind(). This also brings up the question of data validation: I would think that if the user generated a binary file without available seat information, you would want to error out when the binary file is read and not even display a way to try to reserve seats. I have thought about specifying a FBN required format that is used for validation and FBN specific database interaction (like in a Data subclass). How have other people handled putting specifics against the generically generated binary?
Thanks,
Jeff
Can you elaborate on "other relevant parameters"? In my conversion utility, I have only the 2 file names as parameters, which I kind of don't like since it's not very extensible. However, I didn't want to have a ton of required parameters like the field names and lengths, since that wouldn't be very user friendly. Any thoughts?

I just downloaded the SCJD test and I didn't see anything regarding collaboration in the instructions. Some previous postings said that Sun encouraged collaboration on the exam - can someone point me to where this is mentioned? I would like to work with some other folks on this if allowed, but I'd like to see Sun's blessing of this first.
Thanks.
Has anyone taken Sun's prep course for the Developer exam (SL-285) and then taken the Developer exam? I took SL-285 and found it to be pretty easy. I think my instructor was a little lame in the sense of not really covering a lot of stuff, but the material covered seems to be a lot simpler than what I have heard the test covers (and what's in the RHE book for instance). Any insight?
Thanks,
Jeff
