The curious case of the left-handed mouse in webforms

In OAS (, webforms, when using a left-handed mouse to expand a menu, the tree node is not expanding. No error is given. For example, in 'Material Workbench' select the '+' to expand 'Organizations' in the menu. Left and right button does not do anything. Also, the left handed users are having difficulties in moving

Creating PDF’s with PL/SQL and itext

There are several ways to create PDF's, on the client (e.g. PDFCreator) or on the middletier. But to create PDF's merely with packages in the database, that's another story. Even Apex uses some Java on the middletier. The product PLPDF on the other hand is a well known utility which provides this functionality (using open-source 'itext'), but.. you have to pay for this. So why not do it ourselves with itext, open-source (answer: a lot of work and knowledge of Java...).

Internet Explorer crashes with Oracle forms / Jinitiator

Problem: when running form modules using Internet Explorer and JInitiator 1.3.1.x, the browser window opens and crashes immediately before the applet starts.

Sun JRE instead of Jinitiator with Forms and Webutil

Running Forms and Webutil with Sun Java 5.0.6 instead of Jinitiator. And you know what:  it’s faster and has more functionality I’ve been told… First you need the java-file. In this case: jre15006.exe. Initially I found it hard to find on the site of Sun – didn’t even know the name of the file I
