JDBC RowSet DML Sample

Question

Hello,
Excuses for school English + google,
With javac : error: AirlinesDML.java:42: unreported exception java.sql.SQLException; must be caught or declared to be thrown private static RowSet rowset = new OracleJDBCRowSet();
With Java version "1.5.0_06".
I am deroute because the throws SQLException east declares in the code!
If a person can m help that would be sympathetic nerve.
Thank,
Claude
