PostgreSQL 7.3 and JDBC3

Hello!

Tomorrow a tried to compile new postgres with JDBC3 support. I used
J2SDK 1.3.1_04, 1.4.0_01 and 1.4.1_01 and ant 1.5.1. Unfortunately, i
receive error messages from ALL jdk versions. Here my classpath:
.:/usr/local/j2sdk1.4.1_01:/usr/local/j2sdk1.4.1_01/jre/lib/ext.

This is an error messages:

Please, help me to compile it with JDBC3.
