I implemented a small webservice from wsdl using JAX-WS. I'm trying to deploy it to JBOSS app server and getting the error below. I didn't specify any bindings neither in sun-jaxws.xml nor in service implementation class with annotations. What could be the reason for this? I use JBOSS 4.2.2_GA and JAXWS 2.1.3 anonymous wrote : SEVERE: WSSERVLET11: failed to parse runtime descriptor: java.lang.Error: javax.xml.soap.SOAPException: Unable to create SAAJ | meta-factoryorg.jboss.ws.core.soap.SAAJMetaFactoryImpl | java.lang.Error: javax.xml.soap.SOAPException: Unable to create SAAJ meta-factoryorg.jboss.ws.core.soap.SAAJMetaFactoryImpl | at com.sun.xml.ws.api.SOAPVersion.(SOAPVersion.java:166) | at com.sun.xml.ws.api.SOAPVersion.(SOAPVersion.java:68) | at com.sun.xml.ws.api.BindingID.(BindingID.java:304) | at com.sun.xml.ws.transport.http.DeploymentDescriptorParser.createBinding(DeploymentDescriptorParser.java:281) | at com.sun.xml.ws.transport.http.DeploymentDescriptorParser.parseAdapters(DeploymentDescriptorParser.java:222) | at com.sun.xml.ws.transport.http.DeploymentDescriptorParser.parse(DeploymentDescriptorParser.java:133) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4124206#...
