NullPointerException thrown when using RSS binding on a Java component
implementation class that does not have a get() method
-----------------------------------------------------------------------------------------------------------------------------
Key: TUSCANY-3111
URL: https://issues.apache.org/jira/browse/TUSCANY-3111
Project: Tuscany
Issue Type: Bug
Components: Java SCA RSS Binding Extension
Affects Versions: Java-SCA-1.5
Environment: SVN Revision 786928
Linux
Reporter: Mark Combellack
Assignee: Mark Combellack
Fix For: Java-SCA-Next
The RSS binding can support two types of Java implementation classes that
* extend org.apache.tuscany.sca.binding.rss.collection.Collection
* Do not extend org.apache.tuscany.sca.binding.rss.collection.Collection but
have a getAll() method that uses the Tuscany Data API
The support for this is provided in the getFeed() method of
RSSBindingListenerServlet in the binding-rss-rome module.
Unfortunately, currently if you attempt to add an RSS binding to a Java
component implementation that does not have a get() method then the following
NullPointerException is thrown:
Exception in thread "main" java.lang.NullPointerException
