Hey guys,
I have just shifted to OpenJPA and with a bit of fiddling around I have just
managed to get it compiling and make it to runtime, atleast briefly :)
I am quickly greeted with the error message of
Could not locate metadata for the class using alias "Country". This could
mean that the OpenJPA enhancer or load-time weaver was not run on the type
whose alias is "Country". Registered alias mappings: "{Country=null}"
<openjpa-1.0.0-r420667:568756 fatal user error>
org.apache.openjpa.persistence.ArgumentException: Could not locate metadata
for the class using alias "Country". This could mean that the OpenJPA
enhancer or load-time weaver was not run on the type whose alias is
"Country". Registered alias mappings: "{Country=null}"
The catch is with toplink libraries, it works fine.... so far my setup has
been pretty straight forward with all the openJPA libraries added AND the
persistence library configured to the following...
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
