Tnx Dain,
it's in JDBC request, that's where I need it.
I added this driver into JDBC Driver Properties (soapUI Preferences) manualy and it's working.
For others, it goes something like this:
Driver: SOLID/solid.jdbc.SolidDriver
Conn String template: jdbc:solid:://<HOST:127.0.0.1>:<PORT:1325>/<USER>/<PASSWORD>
After this, new Data Connection has to be created in Project Properties.
That's all.
I don't know if there is an even easier way to do it.
I though that driver will just appear after i copied it into \bin\ext\, but it didn't (Build soapui-pro-3.6.2-daily-2010-11-10-[2], Build Date 2010/11/10 02:52).
