Image pic = Toolkit.getDefaultToolkit().createImage(_fnSrcCom);
int width=pic.getWidth(null);
int height=pic.getHeight(null);

Hi all,
A bit of advice required. I have been contacted by a client who has an iPhone application that talks to web services hosted on a J2EE Application Server. We are entertaining the idea of offering him a hosting solution on our existing server.
Our server is Windows 2003 Standard running IIS6 and Sql Server 2005. We already host a nubmer of websites (all .NET).
Firstly, are there any implications for trying to run a J2EE application server alongside IIS, and does anyone have any recommendation for an application server.
I know this question is vague but I'm just trying to figure out if its even worth pursuing at this point.
Thanks
The only thing unpredictable about me is just how predictable I'm going to be.

Of course, IIS & J2EE application server reside in the same host. You may install - Apache Tomcat 6.x or GlassFish.

{7,5},{6,6},{5,7},
{6,7},{7,6},
{7}
}
i use this in java..
//the initiation
protected int zigzag[][] = {
{0, 1, 5, 6,14,15,27,28},
{2, 4, 7,13,16,26,29,42},
{3, 8,12,17,25,30,41,43},

{35,36,48,49,57,58,62,63},
};
//the method
public void zigZagScan(int blkIn[][],int buffOut[])
/* Desk: Method for zigzag scanning as a pattern of scanning in RLE
I.S : array 2D of 8x8
F.S : array 1D of 64
*/
{
int row, col;
for (i=0;i<64 ;i++ )
{
row = zigzag[i]; //i want to use row = zigzag[i].row
col = zigzag[i]; //i want to use col = zigzag[i].col
buffOut[i]=blkIn[row][col];
}
}
could any one tell me what is the suitable sintax in java?
thanx

In a Class, I have a move method. This Class is going to draw a graphic by lines using drawOval() and drawLine(). When the graphic is still, it is drawn correctly. When I try to use the move(), hide(), draw() methods it doesn't hide it completely, it leaves a few lines in its trail. Is there a way I can group it all before I start moving it? otherwise how do I go about making sure it's all hidden before moving?

What do your methods do?
How does the repaint get called?
Some code snipits might just help in getting an answer. There are some very clever people here, but no-one can second guess the code you have written.

I take it you didn't write this because if you did you would know how to do it.
What letters are given to the axes on 2d graphs?
X and Y.
Which axis controls horizontal movement?
The X axis.
Which axis controls the vertical movement?
The Y axis.
How would someone go about stopping the vertical movement of an object on a graph?
Remove the commands(lines of code) which control the Y axis.

i found the code for sending e-mail , but my problem is that mail is not received by the recipient .
public void postMail(String recipients[], String subject, String message, String from) throws MessagingException {
boolean debug = false;
Properties props = new Properties();
props.put("mail.smtp.host", "smtp.gmail.com");
System.out.println("step 1 ");
Session session = Session.getDefaultInstance(props, null);
session.setDebug(debug);
Message msg = new MimeMessage(session);
InternetAddress addressFrom = new InternetAddress(from);
msg.setFrom(addressFrom);
InternetAddress[] addressTo = new InternetAddress[recipients.length];
for (int i = 0; i < recipients.length; i++) {
addressTo[i] = new InternetAddress(recipients[i]);
}
msg.setRecipients(Message.RecipientType.TO, addressTo);
msg.addHeader("MyHeaderName", "myHeaderValue");
msg.setSubject(subject);
msg.setContent(message, "text/plain");
Transport.send(msg);
}
i call this method with
String [] st = new String[1];
st[0] = "nuwan";
this.postMail(st, "test", "prasadbuddhika42@gmail.com", "prasadbuddhika42@gmail.com");
can anyone tell me what is wrong in this code ?

Gmail SMTP server requires authentication and uses SSL.
You should add following to your properties:
mail.transport.protocol=smtps
mail.smtps.host=smtp.gmail.com
mail.smtps.user=your gmail username
mail.smtps.password=your gmail password
mail.smtps.auth=true

Please, check carefully the code, I'm a bit rusty with Java...
public class Main {
static String []_keys= {"abc", "def", "ghi", "jkl","mno","pqrs","tuv","wxyz"};
static char [] _out;
public Main() {
}
static private void comb(int [] iKeys, int iIndex)
{
int i;
int iKey = iKeys[iIndex]-1;
for (i=0; i<_keys[iKey].length(); i++)
{
_out[iIndex] = _keys[iKey].charAt(i);
if ( iIndex == iKeys.length-1)
{
System.out.println(_out);
}
else
{
comb(iKeys, iIndex+1);
}
}
}
public static void main(String[] args) {
_out = new char[100];
int [] iKeys = {1,2,3};
comb(iKeys, 0);
}
}

Just add the method StringToArray and change a bit main , for instance:
public static void StringToArray(String sKeys, int [] iKeys)
{
int i;
for (i=0; i<sKeys.length(); i++)
{
iKeys[i] = (int)(sKeys.charAt(i)-'0');
}
}
public static void main(String[] args) {
int [] iKeys;
String s = "123";
iKeys = new int[s.length()];
StringToArray(s, iKeys);
_out = new char[100];
comb(iKeys, 0);
}

Why?
Is it an assignment (i.e. homework?)?
Anyway you can easily figure out the necesary modifications, I suppose

This sounds like school work to me.

The idea is that your actually ment to learn how to do this, not pass other peoples work as your own.
IMO your a lazy cheat.

What have you done so far?
Have you troubles with the Java language or with program logic?
Please be specific.
