tabbing in JTable

[lavanya subramanian]

hi guys,
i have a JTable in one JInternal Frame and set of textfields in the second JInternal frame.when i hit a insert button ,a new row will be added to the JTable and after entering a value for that cell and if i hit tab key,the focus should go to the first text field in the second JInternal frame.
i have tried adding a Key Listener and if the event was from tab key do,
table.setNextFocusableComponent(jTextField1);
this is not setting the cursor to the textfield instead setting it to the next element in the table.
i have tried extending JTable and overridding the isFocusTraversable() method,with returning false, but this time it takes the focus from the table itself.
i don't want this to happen,what i want want is that the should be intial focus on the JTable and if the selected row and column is the last and hitting the tab key, the focus should go the second JInternal frame.

is it possible,if so how,
thanks in advance,
lavanya
