Well, really not so much. I'd already found it and I'm not seeing where (in what file) to register the filters. Is that in web.xml? I went to the LoggingFilter java doc and tried to click through to the com.sun.jersey.api.container.filter link to try to learn more about the base class but the link is dead. At this point I don't understand how to associate the filter with a particular URL or even how to write the filter. Is it essentially a standard servlet filter? That's why I was hoping for a more in depth explanation.

I don't want to change the generated files unless it is absolutely necessary to do so because the database is being modified often and consequently I often have to regenerate the files and don't want to lose work that had been done to them.

I'm trying to handle this by using a servlet filter before/after the Jersey web services and testing the response code after chain.dofilter(). If I get a 404 then I download the requested data from Apple and insert it into my database. At this point I would like to do a redirect/refresh/modify the response object/whatever so that I can return the new data to the client. I've pretty much hit a brick wall. At this point the response object has been marked as committed so I can't alter it do a redirect or anything else. I've tried using wrappers but it contains an internal CoyoteResponse that I can't get to and that's where it is marked as committed.

It describes how to register a logging filter at https://jersey.dev.java.net/nonav/apidocs/1.0.3.1/jersey/com/sun/jersey/api/container/filter/LoggingFilter.html. This isn't all that helpful to me - I could really use some more complete examples on how to create and use the filters, especially as part of a Glassfish EE 6 web services project.
