Hi Malaka, That didn't work either but your comment put me into the right direction. I was able to get it working by using importClass(Packages....JSUtils); in the javascript.
Thanks a bunch for responding! Thought of documenting everything in case someone else faces the same issue. Here is my ESB API <?xml version="1.0" encoding="UTF-8"?> <api xmlns="http://ws.apache.org/ns/synapse"; name="MySampleAPI2" context="/MySampleAPI2"> <resource methods="GET"> <inSequence> <send> <endpoint> <address uri="http://demo3177833.mockable.io/students"/> </endpoint> </send> </inSequence> <outSequence> <property name="messageType" value="application/json" scope="axis2"/> <class name="org.example.JSONParseMediator"> <property name="createJSONPayload" value="true" /> </class> <script language="js" key="MyLocalJSEntry2" function="executeMain"/> <send/> </outSequence> </resource> </api> And here is my JS function executeMain(mc){ importClass(Packages.org.example.JSUtils); var obj = {}; var myJSUtilsTest = new JSUtils(); obj.foo = myJSUtilsTest.getTestMessage("echo 123"); obj.tee = myJSUtilsTest.getMessage(); } Your class mediator can be anything but you need to have a plain simple class like JSUtils with public methods which you want to expose to JS engine. Make sure to package everything into the final jar file. Deploy this jar file in <ESB_HOME>/repository/components/lib and restart ESB. public class JSUtils { private static final Log logger = LogFactory.getLog(JSUtils.class.getName()); private ScriptEngineManager manager = new ScriptEngineManager(); private ScriptEngine scriptEngine; public JSUtils() { manager.registerEngineExtension("jsEngine", new RhinoScriptEngineFactory()); scriptEngine = manager.getEngineByExtension("jsEngine"); } public String getTestMessage(String test) { return "Testing JSUtils with " + test; } public Object getMessage() { return "Testing JSUtils with getMessage()"; } public Object parseJSON(String jsonStr) { try { return scriptEngine.eval("(" + jsonStr + ")"); } catch (Exception e) { logger.error("Error when creating native object", e); } return null; } public Object stringifyJSON(Object jsonObject) { try { Object returnObj = ((Invocable) scriptEngine).invokeMethod(this.scriptEngine.eval("JSON"), "stringify", jsonObject); return returnObj; } catch (Exception e) { logger.error("Error when creating native object", e); } return null; } } This should work with ESB 4.8.0 and 4.8.1. Hope this will be useful. Thanks.
