lob, odbc, java and speed

Hi, I have DB2 Workgroup edition, version 7.2, fixpak 7 with a table
column of lob field, sizes of actual data in this field range from 50
to 100 mb. My java application takes FOREVER to query the table and
display the data in this lob column. Any suggestions on how to
increase the speed? Will stored procedures help? Will it help for the
java application to read the lob field in chunks instead of reading it
all at once? Right now for each lob field (contains image data in
binary format) the wait time is about 1-2 minutes which sadly will not
work at all.... :(
