Subject [jira] [Commented] (JUDDI-537) NPE when deleting servicebinding
Date Thu, 05 Jan 2012 15:17:40 GMT

    [ https://issues.apache.org/jira/browse/JUDDI-537?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13180456#comment-13180456
] 

Kurt T Stam commented on JUDDI-537:
-----------------------------------

I'm not sure why this returns null. We have a test that also creates and deletes a binding:
http://svn.apache.org/repos/asf/juddi/scout/trunk/src/test/java/org/apache/ws/scout/registry/qa/JAXR050ServiceBindingTest.java
which runs fine.

Can you add the steps to reproduce?

Thx,

--Kurt

> JAXBMarshaller.marshallToElement(result, "org.uddi.api_v3", element);
> {code}
> which causes the jaxb assertion to fire because result is null (see stacktrace for further
code). I don't know if it is normal that the result is null. If so, the result should not
be marshalled. If it is not unnormal for the result to be null, I don't have an idea why it
is so. :) Hope you have an idea.
