Well i'm not sure if I really understand. But after jfs_debug and xt 1 I got
[1] flag        0x03    BT_ROOT  BT_LEAF
[2] nextindex   2               [5] self.addr1  0x00
[3] maxentry    18              [6] self.addr2  0x00000000
[4] self.len    0x000000            self.addr   0
xtree: [m]odify, or e[x]it:

So I modify 1, then run jfs_fsck -fv
many many error, aFile inode  12 has been reconnected to /lost+found/.

Ater this I can mount filesystem and I see data in lost+found. That really wonderful, but i lost original directory tree. Maybe I want impossible, but can I safe this data better? 
But how I say, This result is really great and, I'm very grateful. If I can't get better result, after all I'm glad for this.

Thank you very much
