I have a working Rest web service that use JBoss Resteasy however when I tried to port it to use GAE I\'m getting this error when executing:
java.lang.ClassN
I used resteasy successfully on GAE. As csturtz mentioned make sure your project has the resteasy dependency.
If yo uare using Maven this should be something like:
org.jboss.resteasy
resteasy-jaxrs
${resteasy.version}
And optionally you also would like to use:
org.jboss.resteasy
resteasy-hibernatevalidator-provider
${resteasy.version}
org.jboss.resteasy
resteasy-jackson-provider
${resteasy.version}
