/**
* SOAP Client action processor.
* <p/>
* Uses the soapUI Client Service to construct and populate a message
* for the target service. This action then routes that message to that service.
*
* <h2>Endpoint Operation Specification</h2>
* Specifying the endpoint operation is a straightforward task. Simply specify the "wsdl" and
* "SOAPAction" properties on the SOAPClient action as follows:
* <pre>
* <action name="soapui-client-action" class="org.jboss.soa.esb.actions.soap.SOAPClient">
* <property name="wsdl" value="http://localhost:18080/acme/services/OrderManagement?wsdl"/>
* <property name="SOAPAction" value="http://www.acme.com/OrderManagement/SendSalesOrderNotification"/>
* </action></pre>
* The SOAP operation is derived from the SOAPAction.
*
* <h2 id="request-construction">SOAP Request Message Construction</h2>
* The SOAP operation parameters are supplied in one of 2 ways:
* <ol>
* <li>As a {@link Map} instance set on the <i>default body location</i> (Message.getBody().add(Map))</li>
* <li>As a {@link Map} instance set on in a <i>named body location</i> (Message.getBody().add(String, Map)),
* where the name of that body location is specified as the value of the "paramsLocation" action property.
* </li>
* </ol>
* The parameter {@link Map} itself can also be populated in one of 2 ways:
* <ol>
* <li><b>Option 1</b>: With a set of Objects that are accessed (for SOAP message parameters) using the
* <a href="http://www.ognl.org/">OGNL</a></li> framework. More on the use of OGNL below.
* <li><b>Option 2</b>: With a set of String based key-value pairs(<String, Object>), where the
* key is an OGNL expression identifying the SOAP parameter to be populated with
* the key's value. More on the use of OGNL below.
* </li>
* </ol>
* As stated above, <a href="http://www.ognl.org/">OGNL</a> is the mechanism we use for selecting
* the SOAP parameter values to be injected into the SOAP message from the supplied parameter
* {@link Map}. The OGNL expression for a specific parameter within the SOAP message depends on that
* the position of that parameter within the SOAP body. In the following message:
* <pre>
* <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
* xmlns:cus="http://schemas.acme.com">
* <soapenv:Header/>
* <soapenv:Body>
* <cus:<b color="red">customerOrder</b>>
* <cus:<b color="red">header</b>>
* <cus:<b color="red">customerNumber</b>>123456</cus:customerNumber>
* </cus:header>
* </cus:customerOrder>
* </soapenv:Body>
* </soapenv:Envelope>
* </pre>
*
* The OGNL expression representing the customerNumber parameter is "<b color="red">customerOrder.header.customerNumber</b>".
* <p/>
* Once the OGNL expression has been calculated for a parameter, this class will check the supplied parameter
* map for an Object keyed off the full OGNL expression (Option 1 above). If no such parameter Object is present on the map,
* this class will then attempt to load the parameter by supplying the map and OGNL expression instances to the
* OGNL toolkit (Option 2 above). If this doesn't yield a value, this parameter location within the SOAP message will
* remain blank.
* <p/>
* Taking the sample message above and using the "Option 1" approach to populating the "customerNumber" requires an
* object instance (e.g. an "Order" object instance) to be set on the parameters map under the key "customerOrder". The "customerOrder"
* object instance needs to contain a "header" property (e.g. a "Header" object instance). The object instance
* behind the "header" property (e.g. a "Header" object instance) should have a "customerNumber" property.
* <p/>
* OGNL expressions associated with Collections are constructed in a slightly different way. This is easiest explained
* through an example:
* <pre>
* <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
* xmlns:cus="http://schemas.active-endpoints.com/sample/customerorder/2006/04/Customer..."
* xmlns:stan="http://schemas.active-endpoints.com/sample/standardtypes/2006/04/Standard...">
* <soapenv:Header/>
* <soapenv:Body>
* <cus:<b color="red">customerOrder</b>>
* <cus:<b color="red">items</b>>
* <cus:item>
* <cus:<b color="red">partNumber</b>>FLT16100</cus:partNumber>
* <cus:description>Flat 16 feet 100 count</cus:description>
* <cus:quantity>50</cus:quantity>
* <cus:price>490.00</cus:price>
* <cus:extensionAmount>24500.00</cus:extensionAmount>
* </cus:item>
* <cus:item>
* <cus:<b color="red">partNumber</b>>RND08065</cus:partNumber>
* <cus:description>Round 8 feet 65 count</cus:description>
* <cus:quantity>9</cus:quantity>
* <cus:price>178.00</cus:price>
* <cus:extensionAmount>7852.00</cus:extensionAmount>
* </cus:item>
* </cus:items>
* </cus:customerOrder>
* </soapenv:Body>
* </soapenv:Envelope>
* </pre>
* The above order message contains a collection of order "items". Each entry in the collection is represented
* by an "item" element. The OGNL expressions for the order item "partNumber" is constructed as
* "<b color="red">customerOrder.items[0].partnumber</b>" and "<b color="red">customerOrder.items[1].partnumber</b>".
* As you can see from this, the collection entry element (the "item" element) makes no explicit appearance in the OGNL
* expression. It is represented implicitly by the indexing notation. In terms of an Object Graph (Option 1 above),
* this could be represented by an Order object instance (keyed on the map as "customerOrder") containing an "items"
* list ({@link java.util.List} or array), with the list entries being "OrderItem" instances, which in turn contains
* "partNumber" etc properties.
* <p/>
* Option 2 (above) provides a quick-and-dirty way to populate a SOAP message without having to create an Object
* model ala Option 1. The OGNL expressions that correspond with the SOAP operation parameters are exactly the same
* as for Option 1, except that there's not Object Graph Navigation involved. The OGNL expression is simply used as
* the key into the {@link Map}, with the corresponding key-value being the parameter.
*
* <h2>SOAP Response Message Consumption</h2>
* The SOAP response object instance can be is attached to the ESB {@link Message} instance in one of the
* following ways:
* <ol>
* <li>On the <i>default body location</i> (Message.getBody().add(Map))</li>
* <li>On in a <i>named body location</i> (Message.getBody().add(String, Map)),
* where the name of that body location is specified as the value of the "responseLocation" action property.
* </li>
* </ol>
* The response object instance can also be populated (from the SOAP response) in one of 3 ways:
* <ol>
* <li><b>Option 1</b>: As an Object Graph created and populated by the
* <a href="http://xstream.codehaus.org">XStream</a> toolkit.
* <li><b>Option 2</b>: As a set of String based key-value pairs(<String, String>), where the
* key is an OGNL expression identifying the SOAP response element and the value is a String
* representing the value from the SOAP message.
* </li>
* <li><b>Option 3</b>: If Options 1 or 2 are not specified in the action configuration, the raw SOAP
* response message (String) is attached to the message.
* </li>
* </ol>
* Using <a href="http://xstream.codehaus.org">XStream</a> as a mechanism for populating an Object Graph
* (Option 1 above) is straightforward and works well, as long as the XML and Java object models are in line with
* each other.
* <p/>
* The XStream approach (Option 1) is configured on the action as follows:
* <pre>
* <action name="soapui-client-action" class="org.jboss.soa.esb.actions.soap.SOAPClient">
* <property name="wsdl" value="http://localhost:18080/acme/services/OrderManagement?wsdl"/>
* <property name="SOAPAction" value="http://www.acme.com/OrderManagement/GetOrder"/>
* <property name="paramsLocation" value="get-order-params" />
* <property name="responseLocation" value="get-order-response" />
* <property name="responseXStreamConfig">
* <alias name="customerOrder" class="com.acme.order.Order" namespace="http://schemas.acme.com/services/CustomerOrder.xsd" />
* <alias name="orderheader" class="com.acme.order.Header" namespace="http://schemas.acme.com/services/CustomerOrder.xsd" />
* <alias name="item" class="com.acme.order.OrderItem" namespace="http://schemas.acme.com/services/CustomerOrder.xsd" />
* </property>
* </action>
* </pre>
* In the above example, we also include an example of how to specify non-default named locations for the request
* parameters {@link Map} and response object instance.
* <p/>
* To have the SOAP reponse data extracted into an OGNL keyed map (Option 2 above) and attached to the ESB
* {@link Message}, simply replace the "responseXStreamConfig" property with the "responseAsOgnlMap" property
* having a value of "true" as follows:
* <pre>
* <action name="soapui-client-action" class="org.jboss.soa.esb.actions.soap.SOAPClient">
* <property name="wsdl" value="http://localhost:18080/acme/services/OrderManagement?wsdl"/>
* <property name="SOAPAction" value="http://www.acme.com/OrderManagement/GetOrder"/>
* <property name="paramsLocation" value="get-order-params" />
* <property name="responseLocation" value="get-order-response" />
* <property name="responseAsOgnlMap" value="true" />
* </action>
* </pre>
* To return the raw SOAP message as a String (Option 3), simply omit both the "responseXStreamConfig"
* and "responseAsOgnlMap" properties.
*
* <h2>Transforming the SOAP Request Message</h2>
* It's often necessary to be able to transform the SOAP request before sending it. This may be to simply
* add some SOAP headers.
* <p/>
* Transformation of the SOAP request (before sending) is supported by configuring the SOAPClient action
* with a Smooks transformation configuration property as follows:
* <pre>
* <property name="smooksTransform" value="/transforms/order-transform.xml" /></pre>
*
* The value of the "smooksTransform" property is resolved by first checking it as a filesystem based resource.
* Failing that, it's checked as a classpath resource and failing that, as a URI based resource.
*
* <h3>Specifying a different SOAP schema</h3>
* <pre>
* <property name="SOAPNS" value="http://www.w3.org/2009/09/soap-envelope"/>
* </pre>
* This is an optional property and can be used to specify the SOAP schema that should be
* used by OGNL.
