Administering the JBoss 5.x Application Server

Transcription

1 Administering the JBoss 5.x Application Server JBoss Application Server (AS) is one of the most popular open source Java application server on the market. The latest release, JBoss 5, is a Java EE 5 certified platform for developing and deploying enterprise Java applications and Web applications. While rich in functionality, administering JBoss AS can be somewhat challenging, as it often requires you to manipulate multiple XML configuration files that are located in multiple locations in a JBoss installation. JBoss AS 5 also differs in a number of ways from previous versions. This course covers all the important administrative tasks that are required to administer this new version of JBoss AS. It starts with installation, architecture, and basic configuration and monitoring, covers deployment and configuration of Web and Enterprise applications, and then moves on to configuration of the many other services that JBoss AS supports, such as the Tomcat-based Web container, JDBC and JMS. It also includes coverage of the many details of securing JBoss AS, as well as advanced topics such as tuning and clustering. It is written to version 5.1.x of JBoss AS, but is in large part consistent with all 5.x versions. The course is focused and informative, and created by experts in the JBoss AS. It will demystify the many, sometimes obscure, details of running and maintaining the JBoss AS, and leave you well prepared to manage JBoss AS installations. Audience: Administrators and web masters who need to maintain applications on the JBoss Application Server. Prerequisites: Familiarity with basic Windows operational skills is required. A basic knowledge of web-based applications, web server, Java, and XML is recommended. Number of Days: 3 days 1.
