Stored procedure calling in soapUI using jdbc request step

hi,
please give me the syntax to call stored procedure in JdbC test step request which is having output parameters and fetch me with the reqult set...
example :
I have created a stored procedure and call it as :
call Sp_name('aa',@value);
select @value;

which would fetch me with a result set in mysql statement.

Same thing i want to call in soapui using JDBC test step:
plese help me.

Note: this is used in my project we are implementing in trial license, if it works fine we would go ahead and buy licensed version, soapUI pro.


Thanks
