More howto's on JDev

This is a link to OTN which has a whole load of howto's for JDeveloper - check it out.

TIFF to PDF (on-the-fly)

I saw this iText come up on a list feed this morning. Someone was looking for a way to store TIFF-Data in the database and present it via a pdf. It's available from SourceForge under an MPL 1.1 license.

iText is a library that allows you to generate PDF files on the fly. The iText classes are very useful for people who need to generate read-only, platform independent documents containing text, lists, tables and images. The library is especially useful in combination with Java(TM) technology-based Servlets: The look and feel of HTML is browser dependent; with iText and PDF you can control exactly how your servlet's output will look. iText requires JDK 1.2.

Understanding the Cost-Based-Optimizer

This OTN article explains why it is sometimes difficult for people to grasp the paradigm of writing good SQL which the Cost-Based-Optimized (CBO) can break down effectively. Often SQL-Statements are still written with the Rule-Based-Optimizer (RBO) in mind and that makes life very difficult for the CBO. This article helps to bring you up to date with what you should be thinking of when writing SQL statements for Oracle10g.

If you are already using or thinking of using JDeveloper10g in your development process and what to enforce Code Auditing then you should take a look at the above press release on OTN.
