Example 1 with Handler

use of org.apache.synapse.rest.Handler in project wso2-synapse by wso2.

the class APIFactory method defineHandler.

private static void defineHandler(API api, OMElement handlerElt) {
    String handlerClass = handlerElt.getAttributeValue(new QName("class"));
    if (handlerClass == null || "".equals(handlerClass)) {
        handleException("A handler element must have a class attribute");
    }
    try {
        Class clazz = APIFactory.class.getClassLoader().loadClass(handlerClass);
        Handler handler = (Handler) clazz.newInstance();
        api.addHandler(handler);
        for (Iterator it = handlerElt.getChildrenWithName(PROP_Q); it.hasNext(); ) {
