I'm using the following stack of technologies *JBoss Server:* jboss4.3CP09/jboss-as *Frameworks:* Spring 2.5.5 + Metro 2.1.7 (jaxws-rt) This is the error I've been gettin (I'm sumaryzing the most important lines): *javax.xml.ws.WebServiceException: Unable to load Provider: Failed to load javax.xml.ws.spi.Provider: com.sun.xml.ws.spi.ProviderImpl* *Caused by: java.lang.IllegalStateException: Failed to load javax.xml.ws.spi.Provider: com.sun.xml.ws.spi.ProviderImpl* *        at javax.xml.ws.spi.ProviderLoader.loadProvider(ProviderLoader.java:96)* *        at javax.xml.ws.spi.Provider.provider(Provider.java:90)* *        ... 171 more* *Caused by: java.lang.NoClassDefFoundError: Ljavax/xml/bind/JAXBContext;* This is how I'm creating the client with Spring <bean id="pcWS" class="org.springframework.remoting.jaxws.JaxWsPortProxyFactoryBean">         <property name="serviceInterface" value="${pc.interfaceName}" />         <property name="endpointAddress" value="${pc.endpoint}" />         <property name="wsdlDocumentUrl" value="${pc.wsdl}" />         <property name="namespaceUri" value="${pc.namespace}" />         <property name="serviceName" value="${pc.serviceName}" /> </bean> *It is worth mention that I ran into another issue with another set of applications using Spring and CXF hosted under the same jboss installation, where the solution was to remove jaxb-api.jar from ${jboss.lib.url}/lib/endorsed directory and that is working good.* Thanks on advance your comments. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/721054#721054] Start a new discussion in JBoss Web Services at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
