As my requirement I am storing the image link in database and through that link I need to access the image in the webpage. For this, I am storing images in my workspace. But the problem is, since my workspace is in C drive, I dont want to store those images in workspace because of the space matter. Can I store those images outside C drive and save the link in database? After that how can I access those in webpage?

View Replies View RelatedEmbedding an executable .jar file on a webpage. I am not a programmer and we use Blackboard Publish to package our Blackboard sessions into a standalone executable .JAR file which gives the user the full Blackboard experience. We want to embed this file on our webpage, so I did some research and I understand I have to use a Japplet (?). I have tried putting the basic (J)applet code I found on the web (modified of course) onto the webpage (see code below) but I get a 'ClassNotFoundException' error. I don't have the ability to define the files that are in the .JAR created by Blackboard Publish. How I would go about embedding this file? I can look at the files within the .jar with Winzip but there seem to be loads of .class files and I am unclear which one my webpage is trying to find!

I want to develop a dynamic webpage (using JSP & tomcat hosted on windows server) which will connect to unix server and on button "Show Files" click on dynamic webpage it should display all the files present in the unix server.
The button click should display the files which i can see when i run "ls -ltr" in unix server home directory.
So, I've seen in google mail that the webpage will automatically update whenever a new mail arrives without the user manually refresh the gmail webpage. I'm curious how this is done. Is it polling? or is it something else? how is this done in java web app?

I successfully added a background image on the Panel but I can't create my JButton image on top of my background image.
ImageIcon piano = new ImageIcon("src/img/piano_backgrd.png");
JLabel backlabel = new JLabel(piano);
panel.add(backlabel, new Integer(Integer.MIN_VALUE));
backlabel.setBounds(0, 0, piano.getIconWidth(), piano.getIconHeight());
JButton volup = new JButton(new ImageIcon("src/img/volup.png"));
volup.setLocation(10, 0);
panel.add(volup);
I'm trying to make a method that takes an image and turns it into a tile image. So if the original image looks like this:
[URL] ....
then the output image should look like this:
[URL] ....
Here's a method that's supposed to do that but for some reason the output image looks the same as the original:
public static int[][] tile(int[][] arr){
int[][] tile = new int[arr.length][arr[0].length];
for (int i = 0; i < arr.length; i++) {
tile[i]=arr[i];
}
return tile;
}
I recently changed the method and the error message I'm getting is "bad operand types for binary operator '+'. Here's the method:
public static int[][] tile(int[][] arr){
int[][] tile = new int[arr.length][arr[0].length];
for (int i = 0; i < arr.length; i++) {
for(int j=0; j<arr[i].length;j++){
tile[j]=(tile[j])+(arr[i]);
}
}
return tile;
}

View Replies View RelatedI'm using MS Access database. What I want to do, is to get all names of my tables in database.My SQL query :
SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES
is it correct? I found it in one example and didn't change anything.
I could of course execute this and check, but the problem is, that it returns ResultSet(I'm using Java), and I do not know how to manipulate this object in this situation.Cause usually ResultSet contains columns and rows, I think now I should get only bunch of String values.
I am trying to make a program where a ball moves up continuously when you press space, then begins to move down when you reach a certain point. My method for this is to have a timer, and have a method that does this: When you press space, add 10 y coords every second (using a timer), and if you reach 470 y, then begin to drop 10 y coords. I made a method to hold the keylistener, and am running that method inside the actionPerformed method which is within another class. However, since it is a method, I cannot add my keylistener to my frame in the main method.
