Re: [jetty-users] Dynamic Servlet Registration

[Jan Bartel <janb@xxxxxxxxxxx>]

Hi Ken,

Wow, that's old! jetty-7 is up to 7.6.13, not to mention the whole
jetty-8 series, and jetty-9.0, and jetty-9.1 (for servlet 3.1).

Moreover, isn't it confusing for Grails users that the Tomcat version
in use supports servlet 3.0, but the jetty version doesn't??? Really
sounds like Grails needs to update a version - do you have any
contacts within Grails to advocate for that?

Certainly it would make a lot of sense for you if the jetty plugin was
updated to jetty-8 or jetty-9 so that your servlet 3.0 code will work
for both containers ....

If you're reaaaaaally stuck on jetty-7.x, then possibly the best thing
to do is to look at an example of using jetty in embedded mode, like
this one:
http://download.eclipse.org/jetty/stable-7/xref/org/eclipse/jetty/embedded/OneServletContext.html

This jetty doco page, whilst being for jetty-9, might still be of use
to you too: http://www.eclipse.org/jetty/documentation/current/embedding-jetty.html#d0e16410

Finally, please let me re-emphasise how useful it would be for Grails
to update to a more recent jetty version :)
