Question about JamaMatrix in Visad

Hi, Bill and all,

Do we need to install the Jama package from NIST before using
JamaMatrix in Visad? When I tried to use JamaMatrix, the error message
said that Jama package needs to be installed. I reviewed the matrix
subpackage in Visad and it alreay includes all classes in Jama package
from NIST, and the only difference is that class name Matrix is
changed to JamaMatrix.

Can somebody help me out on this?

Thanks a lot
