Thai C. Tran wrote:Have you tried package java.util.zip ? http://www.exampledepot.com/egs/java.util.zip/CreateZip.html

Hi, thanks for you reply.

I have read the example, but is that means i need to do following:
1. transforms the blob data in the database to a set of files?
2. then packs the files into zip?

is there a way to avoid creating the files, and creates only the zip file

questions about console.info()

Bear Bibeault wrote:Personally, I remove them before a build.

Another tactic I've seen is to create your own wrapper method that does nothing if the symbol console is undefined, and performs logging if it is.

thanks for your suggestion!

questions about console.info()

Bear Bibeault wrote:The console methods are supported by a wide range of browsers, but will cause problems if the browser does not support then or if debugging is turned off. Besides, do your customers really want to see your debugging messages on their consoles?

hi bear,

I dont know whether my client likes it or not.

my question is, how do you handle all these console debugging codes? we need to remove it one by one when the code is committed?

questions about console.info()

I am using "console.info()" together with firefox firebug to debug js code,

i have following question:

can i leave all these console debugging code in the js file, and if my client is using IE, what will happen? is that going to produce any unhappy outcomes?

in other words, Is "console.info()" for firefox/firebug only, or it is a js built in function?

a very weird defect raised by our client

olivier dutranoit wrote:Hi!

Are you using the j2ee form-based authentication framework?

in a system like that, following can happen :

-you request a servlet, jsp, whatever...
-you are not logged in yet, so the system shows you the login page first.
-after login, the system returns your original request...

could be something...

Yes, i am using j2ee form-based authentication framework.

as you said, after login the system should return my original request, but i HAVE clicks on the menu item, so the list() method should be called in theory.

questions about method overriding

Say I have Class A as super class, and it has method "caller()" which uses "callee()"

Then I have Class B inherits from A, and now I rewrites "callee()", and in the drived class version of "caller()", simple calls "super.caller()"

When Object B's caller() is invoked, is the new version of callee() going to be invoked too?

a very weird defect raised by our client

my client reported a problem that maybe created by session (our project is using a framework which based on struts). the defect is described as followed:

1. Client A logins in, and clicks on menu item, list() method is called in the backend to list a set of products

2. now the client B logins using the same user name with another browser or machine (client A is forced to log out ) .

3. client A tries to click on the 'search' button, but it is routed to the login page, so client A re-login with the user name

4. and client A clicks on the same menu item, BUT now "search" method is called unexpectedly (rather than the list() method)

Can anyone suggest what is the possible reason to the defect?

text alignment

<div class="item">
<label>Bank name:</label>
<span class="value">BNPP MALAYSIA COMMERCIAL BANKA</span>
</div>

on the page, the "BNPP MALAYSIA COMMERCIAL BANK" string is too long, so that the "BANK" goes to second line, but not aligned properly with the first line.

how do i make sure that the two lines are left-aligned properly?? thanks

multiple eclipse projects want to use same set of jar files

Hi folks,

I am using eclipse to do a series of hibernate examples,

each of them is an independent project under same workspace,

but all of them are referring to same set of jar files, e.g. hibernate core jars, jdbc, etc.

currently i need to configure the build path for each of them, which is very tedious, is there any better way to do it?

thanks
