Jetty and/or Servlet-api in JavaFX breaks deployment

I try to embed (use) Jetty into my JavaFX 2.2 applet (which runs in a browser).

My problem is that, to host servlets I need to include the servlet-api-3.0.jar also (for javax.servlet namespaces) besides jetty-server.jar, jetty-servlet.jar and jetty-util.jar.

enter image description here

If I include the servlet-api.jar, my project compiles, but when I run it inside the browser, the deployment fails with the "JavaFX application could not launch due to system configuration (show error details). See java.com/javafx for troubleshooting information." error message.

If I remove the servlet-api.jar (and remove the relevant source) it deploys again.

For the JavaFX project the Java Platform is set to "Default JavaFX Platform", and it would be good to keep it this way to reduce the minimum footprint required.

I'm not a java(fx) expert (I come from .NET world), so I'd appreciate any help!

What are the error details? – Puce
I don't know how to get them, because if I click on the 'show error details' link then the JVM console appears which contains nothing. I don't know how to set this up properly to show errors :/ – Csabi
Does it work when running as "normal" application (not as an Applet)? – Puce
Yes it does run as a normal app :( If I switch it back to "Run in Browser" it fails again. – Csabi
Hm, can you check if the generated JNLP file contains all necessary JARs and that the location of the JARs is correct? – Puce

You have an issue with signing the JARs. I'm not very familiar with signing JARs for JavaFX but here is the documentation:

servlet-api-3.0.jar is what's known as a provided dependency.

It is not needed to be included in your war file, as the web app container (in this case Jetty) provides it for you. In your build tool, just exclude the servlet-api.jar from being bundled in your war file.

Note: jetty-server-9.0.0.M5.jar is also a provided dependency and has the same rules.
