[解决办法]
insert 时把Statement.RETURN_GENERATED_KEYS去掉
[解决办法]
是不是连接字符串写错了，贴出来看下
[解决办法]
conn=DriverManager.getConnection(DBURL,DBUSER,DBPASSWORD);
22: conn.setAutoCommit(false);
23: String sql="insert into article values (auto.nextVal,0,-1,?,?,sysdate,0)";
24: PreparedStatement pstmt=conn.prepareStatement(sql,Statement.RETURN_GENERATED_KEYS);
25: pstmt.setString(1,title);
26: pstmt.setString(2,cont);
27: pstmt.executeUpdate();
楼主的意思好像是用到Statement.RETURN_GENERATED_KEYS 让主键自动增长吗，可以在数据库设置自动增长阿，这样这里就不用显示插入字段了
[解决办法]
看jdbc的doc就知道了，到底支不支持，有什么依赖
