We conducted the several test cases on file locking mechanism of JLan3.7.5 in three scenarios with different applications, including MS Office Word2003, Photoshop, OpenOffice. the interesting thing is  : there is different result with different application on the file locking. three testing scenarios are:
1. Remote Lock/Local Open   
2. Local Lock/Remote Open
3. Remote Lock/Remote Open

here is the results listed below:
Application                         RemoteLock/LocalOpen              LocalLock/RemoteOpen                  RemoteLock/RemoteOpen
MS Office Word2003(MNP)       S(Batch oplock granted)                         S                                            S(Batch oplock granted)
MSOffice Word2003(JLan)      F(No oplock granted)                           S                                      F(No oplock granted)
PhotoShop(MNP)                         F(Pessimistic Lock)                 F(Pessimistic Lock)                    F(Pessimistic Lock)
PhotoShop(JLan)                         F(Pessimistic Lock)                 F(Pessimistic Lock)                     F(Pessimistic Lock)
OpenOffice(MNP)                        S(Batch oplock granted)                      S                                                         S
OpenOffice(JLan)                 S(No oplock granted)                F(after selection of the file type ,   F(No oplock granted)
                                                                                                  the file can’t open with a error
                                                                                                 coming out.)
