LGPL GPL question...

[carl]

Hello, 

I would like to release an application (in java) under the GPL. It uses a
small part of a library that was released under the LGPL. It is my
understanding that this is acceptable since the product I am releasing is
an application and not a library. However, it is not clear to me whether I
am required to include the complete source of the LGPL library I am using,
or if I can just include the source for the small parts I am using? Also,
how are Icons handled? If an icon was LGPL'd, can I just include the icon
or is there a 'source'?

Any help in clarifying these issues is appreciated.
