Hi Bill,

We don't want an instance per request. It doesn't matter at moment actually.
The problem is that it isn't working even with everything singleton (which
is the default scope in singleton). Do we have to do anything special to
flag the RESTful beans as singleton?

The main problem is the a dependency of the RESTful bean is not being
injected sometimes, although the bean itself is always there, thus giving us
NullPointers. In the example Fabio sent it would be the field "Seci" that
would end up being null.

[]s,
