This artifact provides a single jar that contains all classes required to use remote Jakarta Enterprise Beans and Jakarta Messaging, including all dependencies. It is intended for use by those not using maven, maven users should just import the Jakarta Enterprise Beans and Jakarta Messaging BOM's instead (shaded JAR's cause lots of problems with maven, as it is very easy to inadvertently end up with different versions on classes on the class path).

There is a newer version: 35.0.0.Beta1

/**
 * Simple implementation {@link KeyDeserializers} which allows registration of
 * deserializers based on raw (type erased class).
 * It can work well for basic bean and scalar type deserializers, but is not
 * a good fit for handling generic types (like {@link Map}s and {@link Collection}s
 * or array types).
 *
 * Unlike {@link SimpleSerializers}, this class does not currently support generic mappings;
 * all mappings must be to exact declared deserialization type.
