Deploying a Javascript service in Axis2
---------------------------------------
Key: AXIS2-625
URL: http://issues.apache.org/jira/browse/AXIS2-625
Project: Apache Axis 2.0 (Axis2)
Type: New Feature
Environment: Operating system used in the devlopment: Ubuntu Breezy Badger
Software platform: JDK 1.5
Reporter: Oshani Seneviratne
Priority: Trivial
It is now possible to deploy a web service written entirely in javascript on
Axis2. When implementing the javascript service, the user will have the option
of using E4X syntax, which extends the semantics of familiar Javascript
operators and manipulate the XML data with ease.
This feature needs 2 classes (org.sample.javascript.JavaScriptReceiver and
org.sample.javascript.JavaScriptEngine) and the js.jar library from Mozilla
Rhino in addition to the Axis2 libraries.
The JavaScriptReceiver processes the incoming message and extracts the
javascrtipt function name[1] , the arguments / payload to be sent to the
javascript service and the javascript source stream[2]. It then calls the
JavaScriptEngine which uses the Mozilla Rhino API to process the javascript
file. The JavaScriptEngine returns an xml string object to the
JavaScriptReceiver and the latter encodes the result and sends the outMessage.
[1] The operation the client requests.
[2] This is similar to the ServiceClass in a Java service.
