wsimport uses JAXB RI's XJC tool internally to achive XML Schema to Java binding. The default behaviour is strictly as per JAXB 2.x specification. However it does not work for everyone, for example if you want to map xs:anyURI to java.net.URI instead of java.lang.String (default mapping).
There is a JAXB global customization that can help you achieve these tasks:
<?xml version="1.0" encoding="UTF-8"?> <jaxb:bindings xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" jaxb:version="2.0" xmlns:xjc= "http://java.sun.com/xml/ns/jaxb/xjc" jaxb:extensionBindingPrefixes="xjc"> <jaxb:globalBindings> <xjc:simple /> </jaxb:globalBindings> </jaxb:bindings>
Then simply run your wsimport and pass this binding customization file
wsimport -p mypackage -keep -b simple.xjb myservice.wsdl
