Re: Java questions

[owner-java400-l@xxxxxxxxxxxx]

I'm a listener.  Don't know the first thing about Java, but was hoping to
pick up some usefull information by following the list.  That hasn't
happened as there is nothing to follow!  Perhaps all the AS/400 Java
developers are using the IBM-sponsored Java news groups.

I'm not supprised the toolbox doesn't offer a method to position to the end
of a file, or read the last record.  As far as I know, traditional DB
access (e.g., RPG + DDS) doesn't offer these functions either.  I'd expect
to position using what is assumed to be the largest possible key value,
then read forward until EOF, just to be sure, followed by read previous to
get the last record.

Subject:  Java questions




     I have two questions.  First, there seems to be very little activity
on
this java mail list. Could anyone who subscribes to this list identify
yourself.  I promise I won't start mailing you questions.  I just want to
find out how many people are out there listening.
     Second, if anyone is trying to develop applications using the AS/400
Toolbox for Java, I'm disappointed by the methods provided for the
KeyedFile class.  Does anyone have a different opinion? The class does
not seem to provide the capabilities that would be useful for positioning
and reading through a keyed file.  I know the class provides about a
dozen methods for accessing records, but when I try to actually start
using them in a real application, I find them to be lacking.  As an
example, there does not seem to be a method to simply position you to the
end of a file or to read the last record in a file. You can use the
methods provided to attempt to simulate these functions, but I find
myself starting to need to make assumptions about the data to easily
accomplish these tasks and others.  Any comments or suggestions would be
greatly appreciated. Thanks.
