Class ScriptReceiver

org.apache.axis2.receivers.AbstractMessageReceiver

org.apache.axis2.receivers.AbstractInOutSyncMessageReceiver

org.apache.axis2.scripting.ScriptReceiver

All Implemented Interfaces:

MessageReceiver

public class ScriptReceiver
extends AbstractInOutSyncMessageReceiver

An Axis2 MessageReceiver for invoking script language functions. The scripting support uses the Apache Bean Scripting Framework (BSF) so the script may be written in any language supported by BSF. There are two ways of defining the script, either in a seperate file or embedded in-line within the services.xml file. This example shows a services.xml using a seperate script file: ... scripts/myScript.js This example shows a JavaScript function embedded within a services.xml file: ... The script language is determined by the file name suffix when using scripts in seperate files or the script parameter name suffix when using inline scripts.

Method Detail

invokeBusinessLogic

public void invokeBusinessLogic(MessageContext inMC,
                                MessageContext outMC)
                         throws AxisFault

Invokes the service by calling the script function

Specified by:

invokeBusinessLogic in class AbstractInOutSyncMessageReceiver

Throws:

AxisFault

getBSFEngine

protected org.apache.bsf.BSFEngine getBSFEngine(MessageContext mc)
                                         throws AxisFault

Gets the BSFEngine for the script service. The first service invocation creates the BSFEngine and caches it in the Axis2 ServiceContext for reuse by subsequent requests.

Throws:

AxisFault

initScript

protected org.apache.bsf.BSFEngine initScript(MessageContext mc)
                                       throws AxisFault

Initializes the script service by finding the script source code, compiling it in a BSFEngine, and creating an OMElementConvertor for the script.

Throws:

AxisFault

readScript

protected java.lang.String readScript(java.lang.ClassLoader cl,
                                      java.lang.String scriptName)
                               throws AxisFault

Reads the complete script source code into a String

Throws:

AxisFault
