关于jboss中取得连接数据库中的记录的超级问题!!!!!!!!!

我用jdbc连接oracle9
取得记录7000条其中含有oracle的long的类型存到vector中
出现以下错误
java.sql.SQLException: 用尽的 Resultset
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.jav

我该怎么半我用一个星期的时间都没解决这个问题
我的原程序如下
mytable(
id char(4),
content long)
/////////////
stmt=conn.createStatement();
ResultSet rs=stmt.executeQuery("select * from mytable");
while(rs.next()){
mybean mb=new mybean();
mb.setid(rs.getString("id"));
mb.setcontent(rs.getString("content"));


}
