No you don't. You have a function that returns setof
Proc_ConferenceSummary which is different than returning record or setof
record. There is a difference in calling conventions in that you must
specify the output type of a function that returns record when calling it.
This difference is not essential to the problem at hand though.

This only works for functions that return refcursor. Instead of using a
CallableStatement you should just use a regular PreparedStatement and a
SELECT query:
Connection conn = DriverManager.getConnection(...);
PreparedStatement pstmt = conn.prepareStatement("SELECT * FROM
myfunction(?,?)");
pstmt.setInt(1,12);
pstmt.setString(2,"abc");
ResultSet rs = pstmt.executeQuery();
