Victor-Adrian Ichim updated CXF-3291:
-------------------------------------
Issue Type: Wish (was: Bug)
This is not a bug but rather an implementation detail.
For reproducing this problem, after the wsdl generation, change it manually by
adding nillable="true":
<xs:element minOccurs="0" name="id" nillable="true" type="xs:long"/>
If @XmlElement(nillable=true) is not also present on the id field, the problem
appears.
The same scenario tested with Glassfish and Metro implementation gives no error.
> Unmarshalling null value for java.lang.Long generates an empty string
> exception

> Key: CXF-3291
> URL: https://issues.apache.org/jira/browse/CXF-3291
> Project: CXF
> Issue Type: Wish
> Components: JAXB Databinding
> Affects Versions: 2.3.1
> Environment: Microsoft Windows 7 Enterprise, jdk1.6.0_23, JBoss 6.0
> final which contains 2.3.1 version of CXF.
> Intel Dual Core, 3GB RAM
> Reporter: Victor-Adrian Ichim
>
> java.lang.Long is not unmarshalled (while primitive long works)
> Steps to reproduce:
> 1. Create a RPC-LITERAL web service on a stateless session bean with a single
> method like this:
> public ResultDTO compute(FilterDTO filter)
> FilterDTO must contain a java.lang.Long id; property.
> Annotated FilterDTO with @XmlAccessorType(XmlAccessType.FIELD)
> 2. Generate the wsdl file with org.apache.cxf.tools.java2ws.JavaToWS
> 3. Deploy the ear by including the wsdl file also (wsdlLocation is specified
> on the bean for @WebService)
> 4. Start the server and use a client to call the method. Having RPC-LITERAL
> the parameter must be not null in the request.
> So FilterDTO must be instantiated. Do not assign any value to the id field
> (let it null).
> Result:
> 16:40:36,317 INFO [STDOUT] DefaultValidationEventHandler: [ERROR]: For input
