Compiling Postgres 7.2.3 - problem with JDBC

Hi,

I having been trying to compile v7.2.3 with JDBC interface on Solaris
x86, unfortunately I get the following error messages. I am currently
using Java2 v1.4.1_02 and get the following errors.

-- driver:
[available] DEPRECATED - <available> used to override an existing
property.
[available] Build file should not reuse the same property name for
different values.
[available] DEPRECATED - <available> used to override an existing
property.
[available] Build file should not reuse the same property name for

[available] DEPRECATED - <available> used to override an existing

[echo] Configured build for the JDBC2 Enterprise edition driver

compile:
[javac] Compiling 53 source files to
/tmp/postgresql-7.2.3/src/interfaces/jdbc/build
[javac]
/tmp/postgresql-7.2.3/src/interfaces/jdbc/org/postgresql/xa/XAConnectionImpl.java:57:
cannot resolve symbol
[javac] symbol : class RollbackException
[javac] location: package transaction
[javac] import javax.transaction.RollbackException;

..... {contd]

Can anyone suggest how to get JDBC interface compiled.

TIA
