EJAX recognises two kinds of resources: static ones, for example an HTML page but also anything made available outside the EJAX frame. A static resource looks like this:

<resource name="quote">
<url>/quote/car.html</url>
<get>
  <representation content-type="text/html">
    <static-page>
      <filename>car.html</filename>
    </static-page>
  </representation>
</get>
</resource>

Note the representation option. Clients can request a resource in various formats, for example HTML for people and XML for machines.

The opposite of a static resource is a dynamic resource. Such representations are created dynamically. Example:

<resource name="quote">
<url>/quote/car.html</url>
<get>
  <representation content-type="text/html">
  <dynamic-page>
    <html-template>car.html</html-template>
    <response-collection>
      <response-name>car-detail</response-name>
      <response-name>options</response-name>
    </response-collection>
  </dynamic-page>
  </representation>
</get>
</resource>

Not a lot is going on here, and that is on purpose. The real work happens in the creation of the individual response. In EJAX a page resource is just replacing elements in an HTML file with parts received elsewhere.
