Further Reading

If you have not yet read it, I'd advise you read the JDBC API Documentation (supplied with Sun's JDK), and the JDBC Specification. Both are available on JavaSoft's web site.

My own web site contains updated information not included in this document, and also includes precompiled drivers for v6.4, and earlier.
