If this is related to browser caching, this may be the way to fix:
The new file isn't loading because the browser is using the older one stored in a cache.
1) go to Internet options and turn the length of days to keep files in your history to zero.
2) go to 'Advanced' and check the box where it says 'Empty Temporary Internet Files folder when browser is closed'.
And I suppose you are using no-cache statements in your jsp
response.setHeader("Cache-Control","no-cache");
response.setHeader("Pragma","no-cache");
response.setDateHeader ("Expires", 0);
