List ax = new ArrayList();

try

{

Connection Conn = DBConn.getConn();

Statement stmt = null;

Statement stmt1 = null;

ResultSet rs=null;

ResultSet res = null;

String sql="select * from JK_BBS order by bbsid desc";

stmt=Conn.createStatement(1004,1007);

stmt1=Conn.createStatement(1004,1007);

rs = stmt.executeQuery(sql);

while (rs.next())

{

ForumForm ff = new ForumForm();

ff.setBbsid(rs.getInt("bbsid"));

ff.setBbsname(rs.getString("bbsname"));

String sqla="select * from JK_BBSCLUB where forumint= " + ff.getBbsid() + " order by forumid desc";

res = stmt1.executeQuery(sqla);

while (res.next())

{

ff.setForumname(res.getString("forumname"));

ff.setForumid(res.getInt("forumid"));
