[JDBC] New to pgsql-jdbc

Hi, I am new to PostgreSQL. We are using XBow wireless motes with PostgreSQL database(8.0 version). Since XBow already provides DB's structure and we don't have to develop pgsql DB. For our needs, we want to bind pgsql with our database called "Cache" which also support with standard JDBC and Java proxy classes mapping. I wonder which driver I should download and how to develop Java bindings for XBow's pgsql?  How could we generate proxy classes for XBow's pgsql? Can somebody post some links for starter? I am using windows XP sp2/ windows 2003 server. Thanks
