Defining resource base for scalatra with embedded Jetty

Question

I have a scalatra based app with embedded jetty.

My final output structure is /lib /bin /etc and webapp is located under etc.

When launching the webapp there is the line which sets the resourceBase - what is this supposed to be set to in this case?

val context = new WebAppContext()
context setContextPath "/"
context.setResourceBase(???)

When you use a WebAppContext as your chosen ContextHandler in Jetty, you are constrained under all of the requirements for a WebApp.

Namely:

${resourceBase}/WEB-INF/classes/ is the primary source of classes
${resourceBase}/WEB-INF/lib/*.jar is the secondary source of classes and webapp configuration
${resourceBase}/WEB-INF/web.xml is the webapp descriptor (optional in Servlet spec 3.0+)
${resourceBase}/ is the lookup point for various methods in javax.servlet.ServletContext such as:
- String getRealPath(String path)
- URL getResource(String path)
- InputStream getResourceAsStream(String path)
- Set<String> getResources(String path)
Requested resources that don't match any of your servlets or filters, will then be handled by the DefaultServlet, which might serve static resources (such as *.html, *.css, *.js) from the specified ${resourceBase}

This just to name a few of the reasons to properly define your resourceBase.

Good Luck,
