Hi,
I have upgraded to cayanne 2.0.1 from 1.2.1
I have opened the cayenne.xml file with the new modeler and accepted to
upgrade.
then I have generated the dataobjects again and saved cayanne.xml.
I have copied the knew cayanne.jar file to my lib directory, but when I
try to run simple queries I get the following exception:
java.lang.NoClassDefFoundError: org/objectstyle/cayenne/query/Query
see details below.
it seems to be looking for the old Query class.
is it this a bug in the deployment of Cayenne or is it that I am doing
some thing wrong?
cheers
felipe
