Hi.
According to the interface, findByCriteria(String [] criteria) will return the record numbers that match any non-null element of the criteria array. It also says null fields are treated as wild cards. I'm not sure what this means. Sounds like if the criteria array contains a null element, then every record number in the database will be returned. Am I intepreting this right?


May you tell me what do the criteria array contains? I'm confused after reading your question and the supplied doc.
Thanks.

Why not read the definitive reference for design patterns (GoF book)? wrapper = decorator and you can find a whole chapter on this pattern in the book.
Hi,
There is a problem in interface DBMain. The first parameter (key) in the find(String key, boolean lock) method is not defined. I thought it represents the name of the subcontractor.
What do you think?

P.S. I have written to who2contact@sun.com and will post the reply here.

I guess it's pretty clear, though I'm wondering how they'll set up their automatic testing without providing that d**n data file. Well... :roll:


Agree... they don't even give us the "Magic Number" that is included in the data file. And the interface (DBMain) they give us have many problems..
BTW, I have written to who2contact@sun.com some days ago and still do not get a reply from them. Next time I will mail to Monica instead.

Hi,
Did anyone get a "database file" (as stated in "Package of Submissions", pt 2 in instruction.html) in the .jar provided by sun? Mine is missing.
