Enforcing adherence to WSDL bindings in JAX-WS web services
You can add binding extensions in the WSDL document, an then apply the extensions into your applications with JAX-WS support on Liberty.
About this task
Liberty supports the use of the wsdl:binding extension that is required in the JAX-WS 2.2 specification. This topic describes how to define the WSDL extensions, and bind them with the customized extensibility element in Liberty.
Procedure
- Define an extensibility element and map it to the user
that is defined in the WSDL extension. The following example
shows how to bind with the WSDL extension {http://server.respectbinding.jaxws22/}goodBinding.
@XmlRootElement(name = "goodBinding", namespace = "http://server.respectbinding.jaxws22/") public class GoodBindingElement implements ExtensibilityElement, Serializable { private String uri; private QName elementType = null; private Boolean required = null; @XmlAttribute(name = "uri") public String getUri() { return this.uri; } @Override public QName getElementType() { return this.elementType; } @XmlAttribute(name = "required", namespace="http://schemas.xmlsoap.org/wsdl/") public Boolean getRequired() { return this.required; } public void setUri(String uri){ this.uri = uri; } @Override public void setElementType(QName elementType) { this.elementType = elementType; } @Override public void setRequired(Boolean required) { this.required = required; } }
- Add the extensions.xml file into the /META-INF directory of your web or EJB application. This
file defines where the extensions can be used in the WSDL document. In the following example, an entry to set the javax.wsdl.Binding property as the parent type of the goodBindingElement class is added in the extensions.xml file.
The entry also means that the extension {http://server.respectbinding.jaxws22/}goodBinding can be only added under the binding element in
the WSDL document.
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd"> <properties> <!-- XML Binding --> <entry key="org.apache.cxf.bindings.xml-1">javax.wsdl.Binding=jaxws22.respectbinding.server.common.GoodBindingElement</entry> </properties>
- Add the extension {http://server.respectbinding.jaxws22/}goodBinding under the binding element as follows:
... <binding name="EchoPortBinding" type="tns:Echo"> <soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="document"/> <tns:goodBinding wsdl:required="true" uri="http://good/good" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" /> <operation name="echo"> <soap:operation soapAction=""/> <input> <soap:body use="literal"/> </input> <output> <soap:body use="literal"/> </output> <fault name="Exception"> <soap:fault name="Exception" use="literal"/> </fault> </operation> </binding> ...
