maven report

Hi,
We are using soapUI pro trial version. We have a project which is created using soapUI pro. We integrated with maven. Do we have different plugin for pro version in order to generating a report in html format? (I'm using maven-soapui-plugin).
If we want to generate html report, what will values of reportFormat look like? ("html"?)

For Junit integration, is there API (Javadoc) that we could look at?
