Lately I came across the problem that I needed to call some REST resources from within an Jakarta EE 7 application running on a JBoss EAP 7.2 application server inside a company network. For this purpose proxies are used to permit access to specific URLs but block all other request to foreign servers due to security policies. However, the obvious ways to make JAX-RS use a proxy wouldn’t work.

WeiterlesenDue to regulatory requirements, there is an increasing need to log the actions of users. Critical actions might even need to be checked for correctness. This article shows how such auditing of actions in an Adabas database can look like. Therefore, the logs produced by Adabas will be transformed into human readable log files. Afterwards they will be sent to an Elasticsearch or OpenSearch cluster for further processing.

Ein wichtiger Bestandteil bei der Entiwcklung einer Anwendung ist das automatisierte Testen. Hierfür wurden verschiedenste Framworks entwickelt, um neben einfachen Unit-Tests noch weitere Komponenten untersuchen zu können, beispielsweise durch Mocking oder Stubbing. In diesem Artikel möchte ich eine Bibliothek vorstellen, mit der die gesamte Architektur einer Anwendung geprüft werden kann: ArchUnit.
WeiterlesenAt my working place I had the task to develop an Jakarta EE web application where LDAP users from the company can log in and do some stuff. This article is not about what the app was capable of but about the SSO authentication part. One requirement was that the users do not have to log in independently, but that this happens automatically in the background. In the following I would like to explain how I have achieved this.

Since my Raspberry is standing around relatively unused at home, I am constantly looking for ideas to use it sensibly. Then I had the idea to connect the Raspberry to my boxes in my room and use it as a Spotify Connect Client. This allows me to listen to music via the system without having to connect my mobile phone directly to it.

Bei mir war es immer so eine nicht ganz ausgereifte Sache, wie ich meine offenen Aufgaben geregelt habe. Seit einiger Zeit habe ich aber eine zumindest für mich zufriedenstellende Lösung gefunden.
Ein Vorteil von WordPress gegenüber anderen Content Management Systemen sind die vielen, oft auch kostenfreien Plugins. Für meine Installation habe ich aktuell keine kostenpflichtigen Plugins heruntergeladen. Um welche es sich dabei handelt, stelle ich in diesem Artikel vor.
A while ago I was part of a project team with the task to intodruce Oracle Application Express in our company. This tool is used to simply present database querys graphically in a browser application. While most installation and administration steps are well documented, we couldn’t find anything to have an authorization within an APEX app based on LDAP groups. And that’s why I want to present with which solution we came up. In this article I’m referring to APEX in version 5.1.
