JBossWS minOccurs Annotation Question

Issue

    private java.lang.String arg0;

Issue

We create our web services via the 'bottom up' approach by annotating our classes with @WebService.

However, this generates stuff like:

   <xs:complexType name="addUser">
    <xs:sequence>
     <xs:element minOccurs="0" name="arg0" type="xs:string"/>
     <xs:element minOccurs="0" name="arg1" type="xs:string"/>
     <xs:element minOccurs="0" name="arg2" type="xs:string"/>
    </xs:sequence>
    ...

Is there a way to manage the minOccurs value?  Each of these arguments are required exactly once.

Environment

• JBoss Enterprise Application Platform (EAP)
  • 4.3
  • 5.x
• JAX-WS

Resolution

There is no annotation that will directly control the 'minOccurs' attribute, but you can use a JAXB annotation to omit the minOccurs attribute (which defaults to "1").  The key is "required=true":

@javax.xml.bind.annotation.XmlElement(required=true,nillable=false,name = "arg0")
private java.lang.String arg0;

This annotation is added to a class-level field in the transfer object that contains the field with the minOccurs attribute.  Note that this may be in one of the JAX-WS wrapper classes.

As an alternative, once you generate the WSDL, you can manually edit the WSDL and then make your web service use your customized WSDL via the @WebService annotation:

@javax.jws.WebService(wsdlLocation="path/to/your/customized.wsdl")
