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.

Create virtual host with Webcache on OAS

By |2019-09-29T19:25:08+02:00June 12th, 2009|Categories: App. Server|Tags: , , , , |

Creating Virtual Host with Webcache and HTTP-server. Not that high-tech, but takes quite a lot of small steps, and must be done without taking risks in a production environment. I did this with Enterprise Manager, while I did not completely rely on my abilities on updating the $ORACLE_HOME/webcache/webcache.xml ..... , and eventually I had to hand it over to the production-DBA.

Headstart 10g installation/configuration 6.5.4

By |2019-09-29T17:38:36+02:00June 8th, 2009|Categories: App. Server|Tags: , , |

10 years ago the installation and configuration of Headstart was a lot of sweat(r)ing, mostly not automated installation-scripts with a lot of faults in it. And thank God it has not changed!! Scripts are Windows-oriented, never heard of Linux, documentation is not quite self-explainable.

Signing jar-files

By |2009-04-29T11:40:53+02:00April 29th, 2009|Categories: App. Server|Tags: , , |

A project is using Sferyx in Webforms, and the file HTMLEditorLight.jar is used. But 'copy and paste' from outside the form to the editor is not working. Cause: the jar-file need to be signed. To sign a jar-file the tools 'keytool' and 'jarsigner' is needed. But... why not use a script from e.g. webutil: With a few adjustments it's a quite common, usable script.

Several notes on Metalink about this:  602001.1, 430359.1, 550301.1
The issue does not occur when using Sun JRE version 1.4, […]

on Metalink is the best source by the way where it is explained what time-outs you can use best, in this kind of environments

Three parameters of vital importance:
