Java JAXWS Web Service Consumer - Error Resolution

We seek a Java programmer proficient in JAXWS 2.1.7 to rectify web service definitions within an existing project. The task involves incorporating new methods introduced in the web service by updating the WSDL definition file and associated *WebService.java and *PortType.java files. The specific error pertains to a javax.xml.ws.Service.getPort(Service.java:119) call, resulting in a com.sun.xml.internal.ws.spi.db.DatabindingException. The error message indicates an issue with the XmlSchemaType annotation, which is not permitted on a certain property type. Notably, the Java Archive (JAR) runs within a Domino server environment.
