In the course Java for Application Managers the foundations of the Java SE and EE platform, the Java language and the options to manage and monitor Java software are discussed.
The participants become familiar with Java applications and their data types, the object oriented nature of Java, the packaging of Java applications, the principles of garbage collection and the Java thread model.
A key module in the course treats the various logging mechanisms in Java software and the configuration of logging.
Also attention is paid to principles of exception handling in Java and how stack traces can be interpreted.
The Jakarta EE standard is discussed and attention is paid to Jakarta EE Web Components like servlets and JSP's. In this respect the reference implementation for Web Components Tomcat is treated.
The participants also become familiar with Java Management Extensions (JMX) as a standard and API for the (remote) management and monitoring of Java Applications. The principles of memory management in Java and the various options to configure garbage collection are discussed as well.
The final subject of the course is the performance monitoring and performance tuning of Java applications. Optional appendixes about Java Database Connectivity (JDBC) and the Java Messaging Service (JMS) are provided and will be discussed if this is the desire of the class.
The course Java for Application Managers is intended for persons responsible for the monitoring, management and troubleshooting of Java Applications and for other interested persons.
General basic knowledge of computer systems and software development. Programming experience is an advantage in following this course.
In this hands-on course the theory is treated by means of presentation slides and is interchanged with exercises. Demos are used to clarify the theory. The course material is in English. The course times are from 9.30 up and to 16.30.
Participants receive an official certificate Java for Application Managers after successful completion of the course.
