Setting SoapUI Runner test case

Hi, I'm working on my first LoadUI project. Basically, what I'm trying to do is create a misc component that will receive some inputs from the user and depending on the received value, use a SoapUI Runner to send a request to a web service. In other words, I would like to be able to dynamically set which SoapUI project/TestSuite/TestCase will be run by the SoapUI Runner from my misc component rather than using the built in project selection of the SoapUI Runner (maybe use an InputTerminal message?). Searching around in the forum, I discovered that the SoapUI Runner is java based and I found this link to download the component

svn://svn.eviware.com/soapui/trunk/loadui-soapui-plugin

However, it doesn't seem to be available anymore. I guess I need the runner code to modify it in order to do what I want. So is there other way to obtain the SoapUI Runner code? More importantly, I would like to read your opinions about what I'm trying to do. As I mentioned, this is my first Load UI project and maybe the approach I'm using is not the best one.

Thanks in advance,

Alejandro
