--------------------------------------------

Added our implementation, usage example:

<component name="wordUtils" scope="event" auto-create="true" bypass-interceptors="true" class="org.apache.commons.lang.WordUtils" />

> It would be very convenient to be able to define a "component" in components.xml without actually having it be wrapped in a proxy, in cases where I just want to have an object put into application context and have a few setters called on it, but don't need any interceptors installed.
> For a use case, see http://www.jasypt.org/hibernate3.html (the "Providing the encryptor to Hibernate" section) - instructions are given for a convenient way to configure the library using Spring, even though the classes in question (StandardPBEStringEncryptor and HibernatePBEStringEncryptor) were not written as Spring beans. The equivalent code in Seam components.xml does not work, since Seam attempts to proxy the objects, and the classes are final (Javassist throws a CannotCompileException). Since none of the functionality offered by proxies is required, in principle the only requirement to make this work would be a way to turn off proxying. (Presumably Spring does so automatically here.)
> Naturally, there is a perfectly good workaround, which would be to use a @Factory or @Unwrap method on a Seam component and include setter methods to do the configuration. But this is a lot of tedious glue code, and I find the idea of directly configuring the objects in components.xml to be much more elegant.
