Hi All,
I figured I would follow up my questions with a fix that seems to work
and my findings to maybe help somebody down the road.
What the Jersey filter does is look at the incoming path and tries to
matches it against the WebPageContentRegex regex. If it matches it
sends the request to the default servlet and stops any processing. I
think the reason this does not work when the Jersey-Guice plugin is in
place is because the GuiceConfig Servlet is being served so the
default servlet does not come into play so when Jersey defers
processing a 404 error occurs. My understanding of how exactly this
is working is not perfect so please correct me if I am wrong.
The fix I put in place was to use the Guice servlet plugin to serve
the regex for static files and never even send them to Jersey. To do
this I changed the Guice ContextListener code to look like:
//////////////////////////////////////////
// bind web resources
bind(GuiceResource.class);
// this serves the static content
serveRegex("/(images|css|jsp)/.*").with(DefaultWrapperServlet.class);
// setup Jersey
Map<String, String> params = new HashMap<String, String>();
params.put("com.sun.jersey.config.feature.ImplicitViewables", "true");
params.put("com.sun.jersey.config.feature.Redirect", "true");
params.put("com.sun.jersey.config.property.packages",
"net.cknudsen.jerseyexample.web");
serve("/*").with(GuiceContainer.class, params);
/////////////////////////////////
For the DefaultWrapperServlet.class above for now I basically use the
example found on the page
http://stackoverflow.com/questions/132052/servlet-for-serving-static-content
which simply wraps the default servlet of the container. However any
servlet should work.
Anyway I hope that helps somebody eventually, and is not painfully
obvious to everyone but me. Also if what I did looks incorrect or has
issues please let me know.
