>  JDBC LOB . getBtypes methods are not implemented in any Derby version to date: there
is a "place-holder" method that throws a SQLException reporting that the methods are not implemented.
> It would be excellent to have any efficient Derby implementation of the getBytes LOB
methods that provide "random-access" to the binary // character content of database large
objects. The specific context is implementing a Lucene Directory interface that stores indexing
data (index files) and other binary data in a local encrypted Derby instance. 
>  A work around is to write an encrypted RandomAccessFile implementation as a file-sdystem
buffer, perhaps writing to the database on closure. An efficient Derby implementation of LOB
. getBytes would avoid this an make for a clean design. I can think of several reasons why
random-access to LOBs would be valuable in a "hostile"  client environment.
