NPE with DBF 2.0

I currently have your DBF 2.0 driver. It has worked great in the past, but in trying to do some new development, have run into a NullPointerException:

16:06:07,489 ERROR [STDERR] java.lang.NullPointerException
16:06:07,490 ERROR [STDERR] at java.lang.String.getBytes(
16:06:07,491 ERROR [STDERR] at com.hxtt.b.l.a(Unknown Source)

16:06:07,496 ERROR [STDERR] at com.hxtt.sql.f.a(Unknown Source)
16:06:07,497 ERROR [STDERR] at Source)

The query is a simple:

select c.C_SUITE, c.C_STREET, c.C_CITY, c.C_STATE, c.C_ZIP from 'p-master' p, 'c-master' c where c.C_NUMBER = '211263' and c.C_DEPT is null

It seems to work intermittently. This is HXTT DBF 2.0 running in JDK 1.5.0_12.

Any suggestions?

You can use HXTT DBF JDBC 3.0 package with JDK 1.5.X . You're using a very old package. Please read Released Version Log.

How much is the upgrade? Is it USD$291, or does purchasing support for the year at USD$131 allow us to get DBF 3.0?

Thank you.

Purchasing support is enough.
