No, I was answering your question. I thought you'd be able to figure it =
out from the information that I shared already. But no worries, here are =
more details:

1. Download cayenne-project.jar from =
http://search.maven.org/#artifactdetails|org.apache.cayenne|cayenne-projec=
t|4.0.M2|jar and add it to your dependencies. Or if you are using Maven, =
simply include cayenne-project in your pom.

2. Add CayenneProjectModule to your runtime on startup. You are using =
CayenneFilter, so that would look something like this:

<filter>
   <filter-name>cayenne-project</filter-name>
        =
<filter-class>org.apache.cayenne.configuration.web.CayenneFilter</filter-c=
lass>
    <init-param>
      <param-name>extra-modules</param-name>
      =
<param-value>org.apache.cayenne.project.CayenneProjectModule</param-value>=

    </init-param>   =20
  </filter>

This would ensure CayenneProjectModule is loaded.

3. Use the API:

CayenneRuntime r =3D WebUtil.getCayenneRuntime(servletContext);
ProjectUpgrader u =3D =
r.getInjector().getInstance(ProjectUpgrader.class);
String version =3D =
u.getUpgradeHandler().getUpgradeMetaData().getSupportedVersion();
