Tom Purcell updated SM-1307:
----------------------------
Attachment: RestProviderMarshaler.java
A cleaner version of the RestProviderMarshaler included in the zip file. It
also packages the HTML headers in the response into vanilla XML so that the
information, like the Location response on a POST, can be returned to the
caller.
> DefaultHttpProviderMarshaler: Make it possible to extract the XML content
> from the NMR.

> The current implementation of DefaultHttpProviderMarshaler the it is possible
> to construct the location URI by specifying an XPath
> expression(locationURIExpression). Make it possible to extract the XML
> content as well. In order to do this JAXPXPathExpression must change.
> In the SMX JAXPXPathExpression class the evaluateXPath(Object object) method
> calls the javax.xml.xpath.XPathExpression evaluate(object) method. There are
> four implementations of that method in XPathExpression. The one being called
> in the SMX JAXPXPathExpression class returns a String. This String contains
> the VALUEs only, not the tags. This is great when you need a value to build a
> URL but not when you need the actual XML. You need the NodeSet. Another
> version of the XPathExpression evaluate method, evaluate(object, returnType),
> allows you to control the return type by specifing one of the
> javax.xml.xpath.XPathConstants but the SMX JAXPXPathExpression does not
> expose a way to call it.
> The attached file contains the following
> An SVN diff of JAXPXPathExpression in which:
> - Changed:
> protected Object evaluateXPath(Object object) throws
> XPathExpressionException
> To:
> protected Object evaluateXPath(Object object, QName returnType) throws
> XPathExpressionException
> - Added:
> public Object evaluate(MessageExchange exchange, NormalizedMessage
> message, QName returnType) throws MessagingException
> - Changed:
> public Object evaluate(MessageExchange exchange, NormalizedMessage
> message) throws MessagingException
> To call the new version above. It passes in XPathConstants.STRING as the
> QName to provide backward compatibility.
> The RestProviderMarshaler which:
> - Extends DefaultHttpProviderMarshaler and makes use of the nes functionality
> - Adds HttpStatus.SC_CREATED to the check for valid response codes in
> handleResponse(MessageExchange exchange, SmxHttpExchange httpExchange). This
> is to support valid responses to a RESTful POST call.
> Below is a sample XBean config for the new http:provder:
> <http:provider service="wile:wileRestService"
> interfaceName="wileCreate"
> endpoint="wileRestCreate"
> marshaler="#createMarshaler"/>
> <bean id="createMarshaler" class="com.jbi.marshal.RestProviderMarshaler">
> <property name="locationURIExpression">
> <bean
> class="org.apache.servicemix.expression.JAXPStringXPathExpression">
> <constructor-arg
>
> value="concat('http://localhost:8080/wile-www/assetmanagement/assetservice/',/assetRequest/perspective)"/>
> </bean>
> </property>
> <property name="method"
> value="POST"/>
> <property name="contentType"
> value="application/x-www-form-urlencoded"/>
> <property name="contentExpression">
> <bean
> class="org.apache.servicemix.expression.JAXPStringXPathExpression">
> <constructor-arg value="//asset"/>
> </bean>
> </property>
> </bean>
