How to input id data in jtable column 1 and load the detail in other column

Dear all,
I am new to java, I am writing a POS using Java. I want to scan goods barcode into column 1 of a jtable, then the program will load the product's name and price in
column 2 and column 3 from database. And also I want to have another row available where the barcode is scanned in previous row, i.e. I can add multiple products. And then I need to write the good's barcode to database. Please suggest any related article or code example. Thanks.

Thanks.Your scanner will probably be a keyboard wedge, so any input from it will be equivalent to typing on the keyboard. You may be able to set it up to send a character, or sequence of characters that you can interpret as "move focus to the input cell, and input the remainder of the input there", if you can't do that, then you will have to just deal with the fact that people will end up scanning the bar codes into the quantity field.

How to Pass XML Data to a PDF Form and Load it into form fields

I have xml Form data in a string. I would like open a programatically launch a pdf document and pass the xml data as one of the parameters and this xml data needs to load all the form fields.
Any Idea as to how this can be done?

I have the same requirement as Daminu, but from the research I have been doing it seems your reply is only partially true.
If your PDF is an XFA PDF form, with Reader Extensions enabled, and you want to keep the Reader Extensions functionality for a user to use after your programmatic manipulation, then neither of these tools will work (FDFToolkit or iText).
Upon the user opening the file once it has been programmatically modified, the user will see the following:
From what I have read, this requirement can only be fullfilled by use of LiveCycle Reader Extensions Server? Please confirm?

How can I Move data from one column to another in my access table?

I have two columns, one that stores current month’s data and one that stores last month’s data. Every month data from column 2 (this month’s data) needs to be moved to column 1 that holds last month’s data. I then null out column 2 so I can accumulates this month’s data.
I understand how to drop a column or add a column, how do I transfer data from one column to another.
Here is my trial code:
<cfquery name="qQueryChangeColumnName" datasource="#dsn#">
ALTER TABLE leaderboard
UPDATE leaderboard SET points2 = points3
</cfquery>
Unfortunately, I get the following error:
Error Executing Database Query.
[Macromedia][SequeLink JDBC Driver][ODBC Socket][Microsoft][ODBC Microsoft Access Driver] Syntax error in ALTER TABLE statement.
How can I transfer my data with the alter table method?

I looked up the Access SQL reference (which is probably a
good place to start when having issues with Access SQL), and
it suggests you probably need a WHERE clause in there.
I agree the documentation is a good place to start. But you should not need a WHERE clause here.
Too few parameters. Expected 1.
If you run the SQL directly in Access, what are the results? At the very least, it should provide a more informative error message..

APEX CSS - How do I get data in report columns to wrap?

I found information here http://www.orafaq.com/wiki/APEX_FAQ
About How do I get data in report columns to wrap?
This works and another way to do it is by adding the CSS directly into the
Home>Application Builder>Application 137>Page 1>Report Attributes>Column Attributes page
in the Column Formatting area. I added 'white-space:normal' and this works in FF but in
IE it has a different behavior.
In FireFox
testasdgadhad
gadfadgadgadg
adgafhsrgjsgnsfg
nsdfbadfafhafha
dfhadfh
In Internet Explorer
testasdgadhad gadfadgadgadg adgafhsrgjsgnsfg nsdfbadfafhafha dfhadfh
Is there a way to force it so it display in IE the same way that it displays in FF?
The correct display format is FF.
Thanks,
Nestor :)

I have try this because I found it during a search and it makes no difference in IE.
This is what I am using now 'display: block; width: 100px;max-width:100px;white-space:normal'
I also tried 'display:block; width:500px'
If I use the values 'normal' or 'pre' for white-space' it works in FireFox but not in IE, The display block
does not seem to make a difference. It seems that all I need is 'white-space:normal' but again
it does not works on IE.
Thanks,
Nestor :-)

How to call a jsp file from an servlet and access the jsp file objects??

Hi everybody
I have an jsp file where it contains a vector object with some data and I have a servlet that needs to access this vector object . How can my servlet call for this jsp page and get the vector object. ?
then an applet will be calling this servlet to get some other object created with the data contained within this vector object...so each time Applet ask the servlet for the object the servlet need to call for this jsp page somehow
My main question is the communication servlet-jsp
please if u have any clue I will appreciate it
thanks

Hi
There are several ways to share objects between JSPs/Servlets.
You can share objects by putting them in the request-in which case the objects lifetime is limited by that of the request, Another way is to store them in the session, againg the lifetime is limited by the lifetime of the session. To have objects that have to persistent over the application life-span use the servletContext to store the objects.
Any good tutorial should help you get started. Please see the link below for a tutorial on Servlets/JSPs
Note: Local variables in the JSP cannot be shared with other components as their scope is limited to that particular Page/Servlet.

Good Luck!

How do I combine all my calendars into one and delete the others?

I have a work computer, a home desktop, and Apple air laptop and an 1phone 4s.
I use Outlook calendar for all my appointments and only need one calendar.
When I get notifications of my upcoming events on the Oulook page and on my iphone, I get multiple notifications, sometimes as many as 6 times.
How can I combine all my calendars into one and delete the others?

Your old account is the one you migrated, but it has been renamed because the new account had the same name. "Fixing" this is a bit complicated. It is possible to transfer data from one account to the other. See Transferring files from one User Account to another.
A cleaner solution is to do this:
Create a temporary new admin user account with a completely different username.
Log into this new account.
Delete the new account you created before migrating.
Delete the old account you migrated that has the changed name.
Re-migrate your old account from the Mini.
Log into the newly migrated account and delete the temporary account.
And, the simplest solution is to use the migrated account as-is and delete the account you originally made on the new computer.

You cannot. If it is in recovery mode, the data is already gone.
Did you fail to make sure everything was on your computer before updating?

I am using FCP 7.0.3 on my Mac Pro. I bought a new mac book pro and loaded the software on to the lap top but the software is 6.0.3. How do i get the update to the lap top?

.. and by the way, the jump from FCP 6.0.3 to FCP 7.0 (or higher) isn't an "update" It's a full version "upgrade" that has to be done using the install discs (or disc images).
