The documentation below is a combination of DocBook and Javadoc. The docbook is a Maven module in our source tree. If you download or check out our source code from GitHub, you will find it under the 'docbook' directory. Javadocs are generated automatically from the maven build.
In release 3.1.0.Final, most of the classes deprecated in the 3.0.x generation of releases are deleted or moved to an optional module. For some guidance in upgrading, see Upgrading from Resteasy 2 to Resteasy 3.
