wadi clustering - jetty7

[Trygve Hardersen <tr...@jotta.no>]

Hi

I'm trying to get WADI clustering to work with Jetty7 and the latest
Geronimo 2.2 snapshot. I package our application as a WAR inside an EAR
which is then deployed as a CAR to Geronimo. With Jetty6 the difference
between the non-clustered and WADI-clustered plugins were:

1. Switch the Maven dependency and car-maven-plugin deploymentConfig from
org.apache.geronimo.configs/jetty6-deployer to
org.apache.geronimo.configs/jetty6-clustering-builder-wadi in pom.xml
2. Add <clustering-wadi/> to plan.xml

When I do this with Jetty7 I get the following build time error:

I looked a bit in the source and it seems to me like the
WADIJettyClusteringBuilder is unable to find the WAR module (which is also
what it is saying). Am I missing something here, or could this be a bug
somewhere in Geronimo? I've tried many different dependency configurations
but I'm always getting the same error.

I have a sample application, used in GERONIMO-4756, that shows the problem.
It simply tries to deploy the web-plugin module using WADI clustering as
described above. Please let me know if I should create a bug for this.

Many thanks for your help and effort!
