OpenEJB does not restrict you to just these data types or require you to use an ejb-jar.xml to declare them.

• You may install your own PropertyEditors and package them with your app.
• Java Generics are supported (e.g. List<URI> myURIs)

The source for this example is the "custom-injection" directory located in the openejb-examples.zip available on the download page.

$ mvn clean install

Which should create output like the following.
