Hello there,
I know that this is not an ideal time (Friday afternoon and all that), but I
have a problem migrating from 1.4.18 to 1.5.0.
I have a business class which reads properties from its .xml properties
file. I used org.apache.wicket.markup.html.PackageResource to start doing
this, but I find that this class is now in a different package
(org.apache.wicket.request.resource.PackageResource) without the methods
that I use.
Does anyone know a good way to read an .xml properties file in 1.5? (I set
out a code summary followed by a fuller code extract below.)
Any help would be much appreciated,
Ian
