the very first step is installing the plugin.. just download the nbm from http://sourceforge.net/projects/soapui/files/soapui-netbeans-plugin/3.0 and follow the instructions at http://www.soapui.org/netbeans/installation.html
a simple demo http://www.soapui.org/netbeans/demos/soapui-netbeans-demo-3/soapui-netbeans-demo-3.html
so, end of the quick start..
Edit on 13/10/2009 at 11.12 :
btw, the command line tools of soapui does not come with the plugin.. so, if you want to use them, for instance launch testrunner inside netbeans or whatever, download soapui standalone version from http://sourceforge.net/projects/soapui/files/soapui/3.0.1 , run the executable for installation, and show the path
soapUI-3.0.1/binfor testrunner exe or something..
