Why not --with-java?

Hi all,

I'm trying to compile PostgreSQL 7.2.1 "--with-java" and get errors in the
JDBC-driver. Compilation without java works, and the resulting db-system
works.

My configuration:
    * Debian GNU/Linux 3.0 "woody" (fsn.hu's i386 Binary-1 (20020125))
    * jakarta-ant 1.5
and one of:
    - SUN j2sdk1.4.0_01 (worked best)
    - j2sdk1.3.1 (from elsewhere)
    - SUN jdk1.3.1_02

When using the JAVA 1.4.0, compilation stopped with the missing class(es)
    "javax.transaction.RollbackException"
ANT was compiled anew with ever choice of JAVA and is reported not to work
with the later to JAVAs by PostgreSQLs "configure".

Please tell me a known working configuration, or where to get the
"javax.transaction.RollbackException"-classes

Best Regards,

Armin Faltl
