Monitoring Enterprise Beans 

Use

The J2EE Engine provides options for displaying and storing information in files about all enterprise beans that are deployed on the server, their containers, JAR files, descriptions, types, applications, and so on.

Activities

Visual Administrator

The Runtime tab of the EJB Container Service displays a tree structure of all EJB applications that are deployed on the server, the JAR files that they contain, and all enterprise beans in these JARs. By selecting an enterprise bean, you can modify some of its properties at runtime. For more information, see Runtime Changes in Deployed Enterprise Beans.

Console Administrator

The EJB group of shell commands provides the following shell commands for viewing and storing information about deployed enterprise beans:

·        LIST_BEANS

You can use this shell command to:

¡        View on the command line in a tree structure all enterprise beans, their JAR files and applications

¡        View on the command line the enterprise beans in a specified JAR or application

¡        Store this information locally in a text file

·        BEAN_INFO

You can use this shell command to:

¡        View on the command line information about all bean containers on the server (such as the name of the application, the JAR name, the name of the bean and other bean properties)

¡        View on the command line the container properties of a specified bean

¡        View on the command line information about all bean containers in a specified JAR and/or application

¡        Store this information locally in a text file

For more information about these shell commands, see the EJB group of shell commands (in the Reference Manual).

For more information about how to execute these shell commands, see Connecting and Working Using Telnet.
