Article on combining GlassFish AMX and Management Rules

GlassFish doesn't trade enterprise features such as management and monitoring for Open Source. Masoud Kalali's recent article on java.net is a good illustration of this. It shows how the JMX-based administration infrastructure can be accessed to dynamically change the behavior of the HTTP load-balancer. The article first goes into what JMX and GlassFish AMX's are before introducing GlassFish v2's Management Rules mechanism. The rest is a detailed explanation of how to create and deploy the MBean to manage the weight of the load-balancer algorithm and the corresponding management rule.

Masoud had previously written detailed blog entries about:
- How to Secure GlassFish installation.
- GlassFish version 2 monitoring capabilities
