| Re: [jetty-users] GWT+Jersey+Embedded Jetty+war files query |
Hi
Thanks for responses, but no joy. Trying to be experimental, I set up a single file with configuration as below, to try a number of variants. Seems that anything (so to speak) without GWT will work on the embedded Jetty, so plain Jersey app works OK embedded (so Annotation scanning is ok), but app with GWT and Jersey fails; A plain GWT app without backend server code works OK also; however the GWT 'Web Application Starter Project' fails in embedded but runs in Jetty stand alone. The GWT starter project uses RMI/RPC to manage backend connection, which differs from Jersey REST. All the .war files were created the same way, project cleaned, GWT compiled, etc.
Nothing in the embedded examples seems useful. But since all GWT examples obviously run fine in SuperDevMode which uses an older version of Jetty Embedded the matter seems to be some kind of configuration problem.

Quoting Joakim Erdfelt <joakim@xxxxxxxxxxx>:
Did you configure your embedded-jetty to use the appropriate webapp
configurations?
Of particular interest is the AnnotationConfiguration (which scans bytecode
and looks for annotated classes).

Hi,
Hoping someone can help with a problem I have not been able to solve.
I have a simple GWT application, with a simple Jersey REST server. I am
able to compile and succesfully run it on Eclipse IDE using SuperDev Mode.
I am able to created a .war file from my project, and drop this .war file
into an unmodified stand-alone Jetty (9.4.6) webapps folder, and again it
runs as expected. The .war File Size is 95981747 bytes containing the
appropriate GWT and Jersey jars (if that is relevant).
But when I try to load the .war file into an Embedded Jetty (9.4.2), the
server-side programs will not work at all, as if the server side programs
did not exist. The welcome page is however available, just that it appears
there is no backend. (I am able as well to write and run simple Jersey REST
applications with no dependency on GWT; also able to run simple GWT apps in
embedded mode.) GWT's JettyLauncher.java (which starts embedded Jetty in
Dev Mode) provides no clue. From my reading of the documentation a .war
file should just work with embedded Jetty. I can't understand why one .war
file works in embedded Jetty and another fails, or why a .war file works in
Jetty stand-alone mode, but seriously fails in Jetty embedded mode. Maybe
it's a configuration problem? If so is there a document that shows how to
configure embedded Jetty to work like the stand-alone Jetty?
