Hello,
I am trying to create a schema, and I am receiving the error below, which to me looks like the MappingException class cannot be found. Problem is, I am positive I have all jars from 2.1.3_extensions, and 3-0.download.
I tried yesterday also, with newer versions. I am running a simple ant script posted below error, and the xml to create schema below that.
Any ideas?
