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: Bug
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. JDK
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).
