What will it cost to adopt the JMX specification as my standard for instrumenting Java technology-based functions?

The JMX specification is being developed according to the Java Community Process, and will comprise a separate package for each tier of the management architecture. The Instrumentation tier will be absolutely free. Other tiers can be built from the public specifications or from reference implementations available under Sun Community Source License. Alternatively, you can purchase commercially supported products such as Sun`s Java Dynamic Management Kit (Java DMK), that also offer more tools for developing and deploying management solutions. See Sun for Java DMK licensing information.
