[Gamedevlists-brew] porting a database file from BREW to J2ME

[Aaron I. <ais...@ap...>]

Hello,
 
Well I figure I might as well take advantage of our new freedoms...

I'm doing a port of our Spanish/English dictionary and phrase book
application from BREW to J2ME, and I'm a bit annoyed there is no file i/o
functions in J2ME, just a stream reading function.  The compressed database
was designed to be very efficient in BREW, but I think it needs to be
redesigned from the ground up to be efficient in J2ME.  One small advantage
is that I can rely on the built in zip/jar support to do some of the
decompression work.  The database is read-only, so I don't need to mess with
RecordStores.

1) Has anyone noticed a phone that completely decompresses the JAR,
including non-class files, into memory when the app is first loaded?  That
is, do all known J2ME phones keep the resources compressed until requested?

2) Do any phones degrade in performance when large numbers of small files
are stored in the jar file?

Thank you!
