Hi,
I think that you should be able to have a.so resolve func_b() from b.so but
it will depend on where b.so is placed. For sure the so have to be position
independent (-fPIE option). Can you send us error you are seeing (I presume
you are).
As far as Java goes you either use -jar and then you can only point to
single jar (this is simply how java works) or use -cp to point to list of
directories or jar. You cannot do java -jar a.jar -cp b.jar. You either
have to combine b.jar with a.jar or do java -cp a.jar:b.jar
<name-of-class-with-main>.
Hope it helps,
Waldek
