SOAPProxy throws SAXParseException when soapAction is missing in WSDL and message has attachment

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: 2011-07-05 12:44:49,823 WARN [org.jboss.soa.esb.actions.soap.proxy.SOAPProxy] (pool-41-thread-1) null binding for soapaction [""] ; parsing envelope to discover operation... 2011-07-05 12:44:49,838 ERROR [STDERR] (pool-41-thread-1) [Fatal Error] :2:1: Content is not allowed in prolog. 2011-07-05 12:44:49,840 ERROR [org.apache.catalina.core.ContainerBase.

https://issues.jboss.org/browse/SOA-3148 SOAPProxy threw a SAXParseException when the the WSDL was missing a soapAction and the message had attachment. A code fix has rectified this problem and, as a result, users will no longer encounter this exception.
