Hello, I'm working with jBoss-4.0.5.GA, jbpm-bpel-1.1.Beta3 and jBossws.1.0.3.SP1. I have developed a simple bpel process with and invocation to a external web service. I deploy the process without problems but when I test it I have the following problem: The SOAP message to the web service is : <env:Envelope xmlns:env='http://schemas.xmlsoap.org/soap/envelope/'> | <env:Header/> | <env:Body> | <defaultNS:CapitalCity xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/' xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:defaultNS='null'>ES</defaultNS:CapitalCity></env:Body></env:Envelope> | And the external server answer me with this: <soap:Envelope xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'> | <soap:Header/> | <soap:Body> | <env:Fault xmlns:env='http://schemas.xmlsoap.org/soap/envelope/'> | <faultcode>soap:Server</faultcode> | <faultstring>Error processing request: Invalid namespace 'null' expected 'http://www.oorsprong.org/websamples.countryinfo'</faultstring> | <detail/> | </env:Fault></soap:Body></soap:Envelope> | The problem is that the process set the property 'DefaultNS' to null, but I don't know how to change this. How can I set the DefaultNS different from null? Maybe in the bpel-application.xml file? Should I use the latest version of jbossWS? The web service what I want to invoke is this http://www.oorsprong.org/websamples.countryinfo/CountryInfoService.wso and the operation is CapitalCity. Any idea??
