--------------------------------------

             Summary: WADL generation does not correctly support query parameters
                 Key: CXF-6137
                 URL: https://issues.apache.org/jira/browse/CXF-6137
             Project: CXF
          Issue Type: Bug
          Components: JAX-RS, Tooling
    Affects Versions: 3.0.2
         Environment: Windows/Linux; Red Hat JBoss EAP 6.2.2; Java 7u40
            Reporter: Michael Schechter


I have created a REST API that takes a bean as its only parameter, and specifies the GET method. This converts the bean fields to query parameters. Two of the bean fields are {{java.util.Date}} instances.

When the WADL is generated for this service, the {{Date}} objects are rendered as beans instead of {{xs:dateTime}} instances, which means our clients cannot use the WADL for code generation. 

As far as we can tell, this issue has the same root cause as CXF-5988; it appears that the {{WadlGenerator.doWriteBeanParam(...)}} method on line 807 needs to have the same fix applied where {{java.util.Date}} is treated as a special case.
