The object with the @Inject setter is instantiated within a servlet.
The servlet is configured in web.xml.
Example:
class Foo {
String attrib;
@Inject
public void setAttrib(String attrib) { this.attrib = attrib }
}
class BarServlet extends HttpServlet {
Foo foo;
public void init(ServletConfig initialConfig) {
foo = new Foo();
}
}
