Subject RE: Issue with Falcon API 0.9 - Creating a BundleApp
Date Fri, 05 Aug 2016 03:33:02 GMT
Hi Chandra,    Please check to see if bundle app xsd is in class path. Normally these aren't
external facing APIs of Falcon. Am curious to know what you are attempting. Understanding
that might help us suggest the right fix.
