So I've deployed my app to GAE, but all I get is a 500 error on the index page, which is just a plain crossroads site. Since I am not at all an expert on Java, I need some help with decoding the error log. Do you have any idea what to do in order to make the app work again (it has been working already)?

I got this same error, and it went away when I disabled WADL in my web.xml file (see init-param stanza under the servlet-class tag). The logs hinted at this, where you see wadl references before the crash. I made this change and restarted, and it worked.
<servlet>
<servlet-name>jerseywebapp</servlet-name>
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.feature.DisableWADL</param-name>
<param-value>true</param-value>
</init-param>
