jaxws client proxy validation error after recreation [Virus checked]

[jan . minaroviech]

Hello,

I have a strange error and don't know what could be a reason. Maybe 
someone has an idea.

i'm using spring 2.5.x, jboss 4.0.4, application is bundled as EAR and 
using CxfServlet and default cxf configuration.
 <value>classpath:META-INF/cxf/cxf.xml</value>
 <value>classpath:META-INF/cxf/cxf-extension-soap.xml</value>
 <value>classpath:META-INF/cxf/cxf-servlet.xml</value>

When service is invoked, its implementation is calling another webservice 
using client fetched using following code:
                        JaxWsProxyFactoryBean factory = new 
JaxWsProxyFactoryBean();
                        factory.setServiceClass(serviceInterface);
                        factory.setAddress(address);
                        factory.setWsdlLocation(wsdlLocation);
                        factory.setServiceName(QName.valueOf(serviceName
));
                        factory.setProperties(new HashMap<String, 
Object>());
                        factory.getProperties().put(
"schema-validation-enabled", new Boolean(schemaValidationEnabled));
                        T port = (T) factory.create();

It's working perfectly until i call this code again (even if with the same 
parameter values). After second and later initilialization i always ends 
with error:

any idea why?

i tested the same process of creating client proxies for client of 
"wsdl_first" sample, and there it's working without problems (but of 
course, it's completly different setup)

best regards
