This artifact provides a single jar that contains all classes required to use remote EJB and JMS, including
all dependencies. It is intended for use by those not using maven, maven users should just import the EJB and
JMS 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).

/**
* Implementation of DynaBean
that wraps a standard JavaBean
* instance, so that DynaBean APIs can be used to access its properties,
* though this implementation allows type conversion to occur when properties are set.
* This means that (say) Strings can be passed in as values in setter methods and
* this DynaBean will convert them to the correct primitive data types.
*
* IMPLEMENTATION NOTE - This implementation does not
* support the contains()
and remove()
methods.
