Unable to download/compile postgresql.jar for PG 7.3 with JDK 1.4.1

All:
This is a brand new installation of PG 7.3 (i.e., no old versions of the
JDBC jar file exist).

I've tried several methods of getting a working driver. First, I
obtained pg73jdbc3.jar from the d/l site. In trying to test it with
DatabaseMetaData, I get the following odd error on a getColumns() call:

Exception in thread "main" java.sql.SQLException: ERROR:  No such
attribute a.oid

         at org.postgresql.Connection.ExecSQL(Connection.java:393)
         at
org.postgresql.jdbc2.DatabaseMetaData.getColumns(DatabaseMetaData.java:1880)
         at com.sysd.sql.SchemaInfo.main(SchemaInfo.java:639)

If I'm interpreting the comments on the JDBC 2.0 Compliance site
correctly, column-type metadata should be supported in PG 7.3.

Next, I tried compiling from source using the --with-java flag to
configure. The 1.4.1 compiler complains about uses of deprecated
classes/methods and missing symbols, and finally craps out:

-----------end extract---------------

I'm guessing these problems are due to the compile problems mentioned in
the archive for jdk 1.4 back in mid-November.

What am I doing wrong? What should I do next? Any hints appreciated.
