Steps to Reproduce: Use quickstarts/webservice_proxy_basic

1) Open a command prompt and cd to quickstarts/webservice_proxy_basic. Run ant deploy to deploy webservice_proxy_basic. Run ant runtest to test it deployed correctly and works.

2) Use the soapUI testing tool and create a new project with the wsdl: http://127:0.0.1/Quickstart_webservice_proxy_basic/http/Proxy_Basic/Proxy?wsdl

3) Open Request1 and add a value to the toWhom element and send the message. Should get a valid response.

4) Now use soapUI to add an attachment (I added a pdf file). Resend the message. Should still get a valid response. Notice in the soa-p console that the attachment is printed out (as a bunch of giberish).

5) Copy the HelloWorldWSService7545491345617367911.wsdl in server/default/data/wsdl/Quickstart_webservice_proxy_basic_ws to somewhere convenient (I copied it to root), and rename it to HelloWorldWSService.wsdl. Open this file and remove the soapAction="" in the soap:operation element.  

  <binding name="HelloWorldBinding" type="tns:HelloWorld">
    <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
    <operation name="sayHello">
      <soap:operation />


6) Edit jboss-esb.xml in quickstarts/webservice_proxy_basic to use a different wsdl value in the SOAPProxy configuration:

				<action name="proxy"
						class="org.jboss.soa.esb.actions.soap.proxy.SOAPProxy">
						<!-- <property name="wsdl" value="internal://jboss.ws:context=Quickstart_webservice_proxy_basic_ws,endpoint=HelloWorldWS"/> -->
	<property name="wsdl" value="file:///HelloWorldWSService.wsdl"/>

				</action>

7) Use ant deploy to re-deploy the quickstart.

8) Use soapUI to resend the message with attachment. You should see an exception:

9) Remove the attachment in soapUI and resend the message. It should work:

         <!--Optional:-->

SOAPProxy throws SAXParseException when soapAction is missing in WSDL and message has attachment. If the soapAction ="" in the WSDL, then the message is not parsed. If there is no soapAction in the WSDL, then SOAPProxy attempts to parse the document to find the operation in the message, and throws a SAXParseException. See Steps to Reproduce below for more details.
