JDBC in postgresql

Hi:
     I install postgresql in Windows NT and I'm able to query simple
database. I try to configure JDBC in the postgresql package under the
interface directory. I reconfigure the system (JDBC and the rest of the
postgresql) over again using ./configure --with-java. When I compile the
source code using make, I get an error. It says that jakarta/ant not
found. I did see ant under the bin directory of the ant home. I also check
the path. The bin directory containing the cat is in the path. I've no
idear of what's wrong with my configuration. Is there any way that I can
intall JDBC driver with re-configure the rest of the postgresql? The
documentation only menstion that there is such way, but it does not give
any instruction. Thank you for any one that help me. I'm very appreciate.
      Thank you and please give me suggestions or help.
