Which database should we use ?

Hi,
I am a beginner to J2ME and developing an application for PDA,
(where OS = palm ).
in which, I have to manage record of individuals in agroups, so which Database is most suitable.
thanks

If you are talking about storing the data locally on the device, then you son't have any choice: you have to use the RMS (Record Management System). This is part of the MIDP API used to store data persistently on the device. You can look at the API documentation, check out the javax.microedition.rms.* package.
If the data is going to be stored in a real database on a server, then it doesn't really matter (from the MIDP perspective) what database you use, since the client will be accessing it through an http proxy anyways (ASP, JSP, a servlet, a cgi app, etc.), and won't be doing any direct access to the database. In this case you can choose whatever you feel most comfortable with (be it because it's cheaper, better, open-source, you already own a license, etc.).

You could use Microsoft Office for Mac, but I would recommend iWork! It's a better set of applications for a much better price. I have used both and I prefer it over Office. And Pages can not only open Word documents, you can also save documents in Word format. My brother and I both used iWork as an Office substitute when we were in college (I graduated a few years ago and he just graduated last night) and haven't had any compatibility issues.

I have down loaded Aurora,Beta4,firefox. Which one should i use

I have down loaded Aurora,Beta4,and Firefox. Which won should i use.'

That is up to you to decide. For some details about the different versions see https://developer.mozilla.org/devnews/index.php/2011/04/07/new-development-channels-and-repositories-for-rapid-releases/
If you have not used to testing software you should stick with the release version (Firefox 4.0.1).

Which CPU should I use

Hello,
our company want to buy new computers for the developers.
We have to use Windows XP as our OS because of third party products.
We develop J2SE + J2EE.
So my question:
Which CPU should we use?
I searched at google but didn't found any usefull sides about benchmarking an J2SE VM or J2EE VM.
Intel or AMD?
Are there some issues to be regarded?
Is the behavior of the VM different if you use an Intel or an AMD? (X86)
Our AppServer is JBoss 3.2.3.
Has Intel ore AMD some magic improvements for the SUN Java VM?
Any answer would be appreciated.
Thanks,
Oliver

Olli_ger,
Thanks for asking. To add more to the question, what about dual- and
multi-processors, such as Opteron 2xx and 8xx processors?
That is, can, and to what extent, does the Java compiler and the JVM
utilize multi-processors? And how is this done? Threads parceled out?
Using what algorithms? Are there "best practices" for writing code
that can exploit these chips?
Given the recent emergence of dual-core processors from both AMD and
Intel I would think Sun would have a white paper on this, but I've not
been able to find anything.
As I'm about to build a new system, and am looking at a dual processor
board that could take two dual-core chips, I'd really like to know.
Thanks again for opening the issue.

Which listener should be used for JTextArea

Hi,
I need to add a listener for JTextArea particualy when
the text in the jtextarea is changed. I don't think
mouse listener is enough, since the user can use tab to
get to the jtextarea and edit the text. In this case,
which listener should I use. Sample code would be
helpful.
In addition, I have a problem with the jtextarea that
when user uses tab to go to different gui components,
such as jtextfield, jcombobox, jtextarea, jlist, etc, the
tab stays in the jtextarea and keeps appending to it. It does
not go to next component, such as jlist. How can I make it
work?
Thanks in advance,
Pin

It doesn't work. Are you using 1.4 or 1.3? I am using
1.4.
In the 1.4 API, it says that isManagingFocus is
"Deprecated".
Here is what I have:
JTextArea descrptArea = new JTextArea() {
public boolean isManagingFocus() {
return false;
descrptArea.setRows(3);
descrptArea.setLineWrap(true);
descrptArea.addKeyListener(new KeyAdapter() {
public void keyTyped(KeyEvent e) {
// DO SOMETHING
I found the following code which says it will do it.
However, I got the exeception:
java.lang.ClassCastException:
n: javax.swing.KeyStroke
at java.util.TreeMap.compare(TreeMap.java:1081)
at java.util.TreeMap.put(TreeMap.java:459)
at java.util.TreeSet.add(TreeSet.java:205)
Set forwardTraversalKeys = new TreeSet();
forwardTraversalKeys.add(KeyStroke.getKeyStroke('\t'));
forwardTraversalKeys.add(KeyStroke.getKeyStroke(KeyEven
.VK_TAB,
InputEvent.CTRL_MASK));
textArea.setFocusTraversalKeys
(KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS,
forwardTraversalKeys);
Set backwardTraversalKeys = new TreeSet();
backwardTraversalKeys.add(KeyStroke.getKeyStroke(KeyEve
t.VK_TAB,
InputEvent.SHIFT_MASK));
backwardTraversalKeys.add(KeyStroke.getKeyStroke(KeyEve
t.VK_TAB,
InputEvent.SHIFT_MASK |InputEvent.CTRL_MASK));
textArea.setFocusTraversalKeys(
KeyboardFocusManager.BACKWARD_TRAVERSAL_KEYS,
backwardTraversalKeys);
Any idea???
PinI'm not using 1.4 but the class cast exceptions look like they come from : Set forwardTraversalKeys=new TreeSet() etc
try : TreeSet forwardTraversalKeys=new TreeSet()
you cant cast from a Set to a TreeSet because a TreeSet is a Set but a Set is NOT a TreeSet.
hope this helps.

Which situation should we use the text item with the item category TATX

Dear experts!
Thank you for your attention!
I am confused with text item (TATX).
which situation should we use the text item with the item category TATX????
Someone told me that the text item is dummy and should be used as a manual of certain standard item. But the manual may be a book or several papers and it also takes up some inventory not a dummy.
So, could some body tell me what the text item (TATX) exact is and what function it has.
Best regard!
Tangdark

Hi,
you can use TATX if you like to enter a text and to print some information between the item lines.

Which object should i use ?

Hi,
I have a methode that returns several values of different types. Which objet should I use to return these values ? I thought of Vector but somebody told me that there is a better object than Vector.
thanks for your help !
Tex

First, always use an interface over an object if it exists. So, your code should always declare the instance variable as List, not ArrayList or Vector or LinkedList. This allows the implementation to be optimized for the task at hand (e.g. LinkedList for arbitrary insertions or deletions of data, ArrayList for better Iterator performance, etc.) while using the interface for the common List methods (e.g., get(), add(), remove(), iterator(), etc.)
Second, avoid Vector. Sun specifically states in the Collections tutorial that ArrayList is preferred over Vector.

What database should i use for a flash application which i need to record score and name for a scoreboard.

Hi. I wrote down the summary of my project so that you can
understand and answer me more easily:
I have to build an application (a little flash game) in which
I record the number of clicks. I want the player to choose a nick
at the beginning and when he finishes one or all the four choices
of target, i want the application to write his nick and final score
in a database for displaying in a scoreboard (hall of fame). All
the new entries should be sorted according to the score. If the
same nick appears again, it's final score will be modified in the
scoreboard only if is higher then the previous.
I was thinking of creating a variable for the name that is
chosen at the beginning and a variable for the score that is
recorded. When the player finishes the game i want the application
to write his data in the database, and then to display the
scoreboard (let's say top 10 players in the database from the
highest to the lowest score).
I never did this before so i am asking what database shoud i
use? I need a programmer to create one for me? Or can flash
generate the database?
Is the variable the good way or should I aproach the problem
by other means? And if a programmer creates a database in MySql is
that good or he should convert it to XML, or Flash generates the
XML?
Thank you.

I did areal photography one time. What you have listed would not be on my short list for lenses to take at all.
Maybe you could supply a little more info of the 50-100mm ? I am going to guess you have the first version of the Canon EF-S 75-300mm? It is a faily slow lens but if these two are the only possibility, I'd choose it.
It and the XTi will work as a mattter of fact I took two XTi's on my flying photo experience. But I had the fantastic EF 70-200mm. Another thing, there is NOT a lot of room on these aircraft.
EOS 1Ds Mk III, EOS 1D Mk IV EF 50mm f1.2 L, EF 24-70mm f2.8 L,
