Re: JavaLangNullPointerException with SQLJ example

Date: Jan 6, 2000
With JDK 1.1.7b and Oracle JDBC thin driver 8.1.5.0.0 this SQLJ example works correctly. The correct port is 1521, btw.

However, with JDBC Driver 8.1.6.0.0 it does not work correctly:

java.lang.NoClassDefFoundError: java/sql/Ref at
oracle.sqlj.runtime.OraDynamicClosure.classForName(OraDynamicClosure.java:81 )
et cetera
et cetera
et cetera
