Examples of org.apache.catalina.Wrapper.allocate()

org.apache.catalina.Wrapper.allocate()
Allocate an initialized instance of this Servlet that is ready to have its service() method called. If the servlet class does not implement SingleThreadModel, the (only) initialized instance may be returned immediately. If the servlet class implements SingleThreadModel, the Wrapper implementation must ensure that this instance is not allocated again until it is deallocated by a call to deallocate(). @exception ServletException if the servlet init() method threwan exception @exception ServletException if a loading error occurs
