Hi Zhanming,
Are you sure you copied the resource classes from the Bookstore
project? The log states that scanning did not find any resources in
the package "com.sun.jersey.samples.bookstore.resources" indicating
that there are not root resource classes (classes annotated with
@Path) in that package.
The following is incorrect:
> filter("/*").through(ServletContainer.class, params);
it needs to be:
filter("/*").through(GuiceContainer.class, params);
I cannot explain why startup is slow. Perhaps you can send me a maven
project and i can investigate further? I am not sure it is an issue
with Jersey because the two logging statements do not originate from
Jersey.
Paul.
