Please give my advise about connection to mssql by SoapUI. Please pay attention that I have trial version of tool.
In company we use mssql ando I downloaded appropriate jdbc driver. After that I put jar file to directory: soapui/bin/ext
Finally I restart Soap and create jdbc request with following options:
Driver: com.microsoft.sqlserver.jdbc.SQLServerDriver
Connection string: jdbc:microsoft:sqlserver://server_name:1433;databaseName=db_name?user=user_na me&password=pass
SoapUI log tells me:
Tue Mar 26 16:49:33 MSK 2013:INFO:Adding [D:\soapUI-4.5.1\bin\ext\sqljdbc4.jar] to extensions classpath
Tue Mar 26 16:49:35 MSK 2013:INFO:Used java version: 1.7.0_02
But when I press Test Connection error occurs: Can't get the Connection for specified properties; java.sql.SQLException: No suitable driver found

What I do wrong?
Thanks in advance
