Java Class Adapter overview
Use the Java Class Adapter to instantiate a Java™ object and to invoke a sequence of methods on the object.
This adapter accesses Java™ classes from maps. This means, that maps can be created to instantiate objects of a specified class, set values of the public fields for that object and invoke the specified class methods with the specified arguments and retrieve the results that these methods return (as well as public field values that can be modified) so that they can be reused in the map.
You can use the adapter with a Command Server, Software Development Kit, or map in a map rule.
