I have an JTabpane which i use to show the different files in the tabs. I am storing the index no of the tab and the file assciated with it in an hashMap. when i remove one tab obviously the index of the other tabs change. So when i try to change the index of other tabs in the tab.containerListeners removed Event i get an error as Concurrent Resource exception.. can any one let me know how to go about this.. Ie how to change the index of my hash map when the tab is removed..
It's hard to be specific since you haven't showed us the code that is causing the problem.
If you are getting a ConcurrentModificationException (which I can't quite tell from your post) then you are modifying a Collection while you are iterating through it, which is (usually) forbidden.
[edit: Your title says "concurrentAccess Exception", which I think is an EJB thing. Your post says "Concurrent Resource exception", which which I am not familiar.] [ March 20, 2007: Message edited by: Brian Cole ]
