Enclosed is some code which uses jakarta commons-attributes to do the same thing as JDK1.5 annotations does with javadoc (the code is not tested but it is fairly simple so it should work).
BTW: Maybe the ProxyInjector could take an array of IObjectLocatorFactory and takes the first one which does not return null. This way you could combine different IObjectLocatorFatories in one place?

I would be very interested in a 1.4 port of this. Do you think it could use the same annotation based approach, but using Qdox to process instead of the built in 1.5 annotation functionality?

For the cglib proxy you should definately not forward the call to finalize(), because when the proxy gets GC it willcall finalize() on the target and that is not what you want. I think samereasons apply for the other Object methods except equals, hasCode and toStrign. JDK proxies do not forward them as well. Serializing: CGLIB proxies. I think the problem if you just plainlyserialize them withotu writeReplace/readResolve is that if the proxy getsdesiarialized in another VM than the dynamically create class of CGLIB could not be yet there. So this could make problems in clusters etc. Christian On Fri, 11 Nov 2005 00:50:13 -0800, Igor Vaynberg <[EMAIL PROTECTED]> wrote: > more refactoring/tests and some new things: >> SpringWebApplicationFactory - which will pull the webapplication subclass> out of spring application context > > SpringInjector/SpringWebApplica tion - make it very simple to inject > objects > using @SpringBean annotation with lazy-init proxies >> SpringWebPage - autoinitailizes its subclasses using the SpringInjector> > I also deprecated all the old stuff and moved it into > wicket.contrib.spring.old package.
