How to make autoincrement element start from 1?

[John]

Hi all,
In my application , there is a table, see bellow.
  <table name="MSGNODE" idMethod="idbroker">
    <column name="ID" required="true" primaryKey="true" type="INTEGER" 
autoIncrement="true"/>
    <column name="TYPE" required="true" type="INTEGER"/>
    <column name="GROUPID" required="true" type="INTEGER"/>
    <column name="NAME" required="true" size="255" type="VARCHAR"/>
    <column name="OWNER" size="255" type="VARCHAR"/>
    <unique>
      <unique-column name="NAME"/>
    </unique>
  </table>
The start value of ID is 1000, how to make the value start from 0 or 1?
I am using turbine2.2, window2000 and oracle 8.1.6.
