Which API should i use... ???

I want to store an image into databse. Which API is used for this purpose.

JDBC. There's a forum for that too if you have more specific questions about it.

Which API can be used to write to an XML file(web.xml) programmatically

Hi,
I wish to write to the web.xml file programmatically.Could anyone point me to the
API that is to be used.
I am aware of the API to be used for extracting the node and the tag values - com.bea.p13n.xml.util.DomHelper
but this class has only getters and I wish to know which API should be used to set
the xml nodes.
It is important and am looking forward to pointers.
Thanks in advance!

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.

I am a student and need to do my assignments in word. Which application should I use as I have to save all of them in older word version like 2003 to send it to my teacher?

I am a student and need to do my assignments in word. Which application should I use as I have to save all of them in older word version like 2003 to send it to my teacher?

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 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.
