The PVM includes a framework to allow the injection of services and objects that will be leveraged during the process definition and execution. Objects and services required in Orchestra are defined through an XML file. A dedicated parser and wiring framework in the PVM is in charge of creating those objects.
A default environment file (environment.xml) is provided in the installed package.
Currently, following objects are required for the execution environment :
servicePublisher
deployer
serviceInvoker
languageProcessor_XPath
queryExecutor_XPath
expressionExecutor_XPath
processRepository
DOMGetVariablePropertyFunction
Example of implementation classes for these objects are embedded into the Orchestra jar and defined into the environment.xml file.
