13.9.6. Object Graph Navigation Library (OGNL)

The Object Graph Navigation Library is an open source language developed by the Apache Foundation. It is an expression language for obtaining Java object properties. The JBoss Enterprise SOA Platform uses it as the mechanism used for selecting the SOAP parameter values to be injected into the SOAP message from the supplied parameter map. The OGNL expression for a specific parameter within the SOAP message depends on the position of that parameter within the SOAP body.
