This sections explains where all the relevant jar files are located. It also lists Cayenne dependencies.
Cayenne Runtime Framework
The following runtime jars are included in Cayenne distribution "lib" directory:
- cayenne-server-x.x.jar - contains full Cayenne runtime WITHOUT dependencies. Most applications will use only this file.
- cayenne-client-x.x.jar - a subset of cayenne-server.jar trimmed for use on the client in an ROP application.
- cayenne-tools-x.x.jar - Ant tasks
- cayenne-agent-x.x.jar - a Java instrumentation agent that is used to enhance POJO persistent classes.
- cayenne-modeler-x.x.jar - CayenneModeler runtime library. Most applications won't ever use it. It is only needed for the local JNDI hack.
When using cayenne-server-x.x.jar you'll need a few third party jars (all included in "lib/third-party" directory of the distribution):
- ObjectStyle Ashwood Graph Library, version 2.0
- Apache Velocity Template Engine, version 1.3 (and all its dependencies bundled with velocity-dep)
- Apache Commons Collections, version 3.1
- Apache Commons Logging, version 1.1
ROP client dependencies are explained here.
