Remote access from PC using JDBC

[Cavo Vincent Civ AFRL/SNRT]

I am trying to access a remote Mysql database resident on Linux from my PC
via JDBC. I can successfully access the Mysql database from a computer
running Linux and also from a Sun running Solaris 8 both via JDBC. However,
when I try to access the database from my PC I receive the error 'Invalid
authorization specification: Access denied for user: 'xxxx@PCaddress' <Using
password: YES>'. I installed Java, JDBC and the Java code on my PC which run
on the other computers. The only difference is that I had to install Java
1.1.8 from Sun on my PC. I set the CLASSPATH as before except for the use of
backslash in place of slash and uses of ; instead of :. Permissions for user
xxxx are also set on the computer running the Mysql data base in both the
user, db, and host tables. The Mysql logs on the remote computer running
Mysql and Linux do not indicate any access attempt from my PC.

This problem has really got me baffled!! Does anyone know what is wrong??
Thanks.
