When I "translate" the sample SQLJ program (with slight modifications for hostname) found on pages 47ff. in the Java Developers Guide, using the following commandline options,

SQLJ -user=scott/tiger_at_jdbc:oracle:thin:@tr:5521:orcl d:\work\MySQLJExample.sqlj

I get an error. Here is the output:

---

Ora8i> java -version
java version "1.2"
Classic VM (build JDK-1.2-V, native threads)

I've also tried 1521 as the listener port, which is the value that appears in my tnsnames.ora and listener.ora files, but got the same error.

What could be causing the NullPointerException? Any suggestions on how I can narrow this down?
