try {

			String url = "jdbc:odbc:driver={Microsoft Access Driver (*.mdb)};DBQ=E://AccessDb//gf.mdb";

			Connection conn = DriverManager.getConnection(url);

String sql =new String("insert into wxwcb (bh,czr,lxdh,fwzl,fwjg,jzmj,Jbrsj,gfph,wxxm,jbr,wxsj,shyj,shsj,ksyj,"

					+"kssj,fgsyj,fgsz,fgsj,xhyear,xhnum) VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)"); 

			PreparedStatement ps=conn.prepareStatement(sql,1);  //出错了

ps.setString(1,((WxwcForm) form).getBh());

...

ps.setString(1,((WxwcForm) form).getxhnum()); 

			ps.executeUpdate();

			ResultSet rs = ps.getGeneratedKeys();

PreparedStatement.RETURN_GENERATED_KEYS

就是1 所以我上面用了;
出错是这样的:
