Configure sonar and maven to analyze Webapp

We need to analyze a webapp using Sonar The webapp has been developed
using java, ejb's and adf. The structure is as below - Root directory with
main workspace .jws Subdirectories with individual project .jpr's, each
having its own pom.xml
A
|
| a.jws
| pom.xml
|
| - B
| - B/b.jpr
| - B/pom.xml
| - B/src
|
| - C
| - C/c.jpr
| - C/pom.xml
| - C/src
|
We build the Ear for the webapp with maven from the root directory
containing the main .jws and main pom.xml
Looking for pointers on how to get the data for all projects in the
workspace on the dashboard with one maven run, similar to the ear build
for webapp
