Overall characteristics of the Decision Service node

The Decision Service Node is implemented as a Java™ User Defined Node. If you follow the installation instructions, add the node from the IBM® App Connect Toolkit palette as a Decision Service element to a flow. This node can be included in message flows and sub flows.

You have to configure some properties to use the node. The section User interface for developers describes the properties and the section Input and Output Message Format shows the construction of a valid input tree.

The Java Virtual Machine (JVM) of the execution group caches the JMX connection to the application server and decision server. The key for a specific decision server in the name of the configurable service.

Valid message domains for the input tree are XML, XMLNS and XMLNSC. The domain for the output tree is always the one of the input domain. It is highly recommended to use the XMLNSC parser to avoid any namespace conflict.
