Ron Gavlin commented on SMXCOMP-78:
-----------------------------------
Now that the smx-utils refactoring is complete, would it be possible to
re-apply the patch in this JIRA. Also, would it be possible to backport this
patch to the 3.2.x branch?
REST support is becoming a major issue and the camel-rest component cannot be
used within smx 3.2.x since it requires Spring 2.5.x.

> 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>
