Cactus results in JUnit XML format?

I want to execute Cactus tests on my app server and import the generated =
test report into Sonar (qualitiy monitoring tool). Sonar is able to =
import test reports in JUnit XML format. So the question is: is there a =
known way to get (or transform) the Cactus test report in JUnit XML =
format?

I already found issue CACTUS-179 =
(http://issues.apache.org/jira/browse/CACTUS-179) which does not seem to =
be implemented by now. But anyhow - I have not even yet figured out how =
to activate this support for the JUnitReport XML in Cactus. =20

Thank you for help and best regards
