Class EmbeddedScriptingService

com.adaptris.core.services.EmbeddedScriptingService

All Implemented Interfaces:

AdaptrisComponent, ComponentLifecycle, ComponentLifecycleExtension, DynamicPollingTemplate.TemplateProvider, MessageEventGenerator, Service, StateManagedComponent

@ComponentProfile(summary="Execute an embedded JSR223 script",
                  tag="service,scripting",
                  branchSelector=true)
public class EmbeddedScriptingService
extends ScriptingServiceImp

Supports arbitary scripting languges that are supported by JSR223.

You should take care when configuring this class; it can present an audit trail issue when used in combination with DynamicServiceExecutor if your script executes arbitrary system commands. In that situation, all commands will be executed with the current users permissions and may be subject to the virtual machines security manager.

The script is executed and the AdaptrisMessage that is due to be processed is bound against the key "message" and an instance of org.slf4j.Logger is also bound to key "log". These can be used as a standard variable within the script.

Note that this class can be used as the selector as part of a BranchingServiceCollection. If used as such, then you need to remember to invoke AdaptrisMessage.setNextServiceId(String) as part of the script and ScriptingServiceImp.setBranchingEnabled(Boolean) should be true.

In the adapter configuration file this class is aliased as embedded-scripting-service which is the preferred alternative to the fully qualified classname when building your configuration.
