I have few server running same version of web application.
These application run from One of the server always show "funny" results,which likely due to cache/memory/session problem.
For example,
1)delete/change certain data then save to database,database update data successfully.However come to screen still showing old result.
2)I search result of certain document from Internet Explorer,then I log out and login to previous search document.Those search criteria and result still REMAIN there.
Fine,I login with different browser,such as mozila firefox,those search criteria and result showing on screen.

If I leave this issue few hours,then come back to previous screen or document,it was show uptodate info.
I have tried delete server cache,browser cache,db cache.problem still persisted.

P/S:Other 3 server runnig same version of web application no such issue.

for example:
want to program an e-dictionaty

key is A,B,C ........untill Z
value would be serial of word based on key.

if the user select "Z",i want to get related value directly without loop 26 times from A till Z.

for my case(not e-dictionary),the hashmap might have thousand of keys.it is time consuming and effect the performance.

thank you

my program can debug and run completely at JCreator compiler.
however,when i shift my project to netbean compiler,it can't found "keyStoreLib" file.
i have copied "keyStoreLib" to ..\NetBeansProjects\key\build\classes or ..\NetBeansProjects\key\build\classes\key
i guess the error message caused by netbean compiler cant find "keyStoreLib" file from the correct directory path

what the correct directory path for the "keyStoreLib" file?

[solved]no idea,may somebody give me some hints for the question?

Write a method to display a pattern as follows:

2 1
3 2 1
N n-1 3 2 1

The method header is
public static void displayPattern(int n) //Assumption: n <= 99
