Parallel to the 'spring' module is a module called samples. Inside that is a tiger project which contains the transaction Annotations stuff, including a unit test, as well as some more experimental JMX Annotation stuff that Rob did. Also inside samples is a tiger-samples/jpetstore-annotations project which is a version of the JPetstore that is almost identical to the commons-attribute version of the petstore, except it uses the Annotations code. The latter depends on the code from the 'tiger' project. The ant builds and Eclipse projects for these both use and expect JDK 1.5. There's no IDEA projects, since I don't use IDEA.
