[jira] Updated: (TUSCANY-2757) Top down round trip problem where
wrapper elements are marked as nillable by JAXB during WSDL generation
[ https://issues.apache.org/jira/browse/TUSCANY-2757?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Simon Laws updated TUSCANY-2757:
--------------------------------
Attachment: 2757-temp.patch
Here is a patch I'm using to get round this issue. I basically set and nillable attributes found on global elements to "false". I'm not sure is there are configurations where global elements can validly be nillable so want to discuss be committing this work around.

> With a top down scenario where a java interface is generated from WSDL, for example, by using wsimport, and is then used in Tuscany the Tuscany code regenerates the WSDL from the Java interface and in doing so creates XSD based on the generated Java types. In this situation JAXB appears to assumed that the wrapper element types are nillable. This breaks the JAXWS wrapped algorithm that explicitly states that wrapped interface elements should not be nillable. If I remove the generated wrapped element classes and have Tuscany generated the WSDL based on the interface itself then it works.
