Now I want to store the image displayed in the jlabel into the database(oracle).From the above code I dont know how to get the absolute path of the images.
I want to store an image/file into oracle database using jsp.

I need to create a grocery store calculator in Netbeans GUI. It should function as follows:
1. Click "Checkout" 2. Enter item price screen pops up. 3. Input item price, and store price in Item price, subtotal and display in those text fields. Also store item number in number of items and display in text field, all after you click "Ok". 4. Enter item price screen should automatically pop back up. (Loop) 5. Once you are finished with all items, when you click "Ok" or "Cancel" with nothing in the text field. It should calculate sales tax/ total sale and display both. 6. Rest button should reset to the beginning and Exit button should exit program.

The good news is my program works right now. Although I do not believe I am using the setter/getter methods correctly. More importantly I do not fully understand them. I left out the Generated code due to the length.

I have completed an assignment for my university in which I had to make a Java NetBeans project. My project is now completed but now I have to make a setup of my NetBeans project and give the university the setup file, only.
My question is, the software I made has a database attached to it, meaning the purpose of the software is to be used with the database. Values must be saved in the database, deleted from the database etc.. I have used MySQL database connections with the JDBC driver
I have used exe4j to make the .exe file and Setup Factory to make the exe file and setup file respectively. Once I make the setup and run the setup, the application works, ON MY COMPUTER. The computer which made the software. But once I take it to a computer in which MySQL was not installed, the setup installed, but the software did not work.
I am new to java. is there any possibility to store parse tree in database such as mqsql, oracle, etc. My requirement is [URL] ..... I found some code about generating parse tree. my next step is store that tree in database.
So i wanted to try something new like find an image within an image. So for my "find" method I would like to take an image and use it to scan and compare sum of absolute differences with the bigger image. So that the smallest SAD would be the exact image that I am using to scan. What I am thinking is to put each pixel value of both images into two separate arrays and compare them via Math.abs(image1[i][j]-image2[i][j]); . My only problem is that I do not know how to put each pixel value into an array.
Also, If I only want to compare just the green in the picture. I saw that the Pixel class has a getGreen(); method. If I want to find the SAD of the green, would Math.abs(image1.getGreen()-image2.getGreen()); work? I was planning to have 2 nested loops running through each column and row for each image and just find the SAD of the green value.

We have web based application (Oracle DB, Weblogic middle tier) and a applet based application running on the browser.
We have a requirement to Load images from the database (stored as blob) to the client browser and the users can do the lookup on images when needed.
We need this to perform well, so there is no delay for the user experience. We have 2 options:
1. Load the images from the database to the Application Server and keep it. When the client request from the browser comes, download it from the application server.
2. Load the images (asynchronosly) when the user logs into the application and download them to the Client machine? Is this possible? Especially give that it is stored in the database as binary objects? And then load for the user from the client box itself, upon request.
If 2nd option is possible, which once is recommended?
Sir, I'am new to Swing Programming. I have to create an application where an image is displayed on one Label. The same image has to be split in parts and stored in database pert wise. Later the user has to retrieve the entire image by viewing a small part of the image. I have already displayed the full image on the Label, now i don't know how to split the image and store it part wise in the database.
I stored an image into MySQL database using swings and hibernate but I am struggling to retrieve that image from MySQL database and display same image in the jTable cell and same as on jLabel whatever I retrieve from the database using swings and hibernate .
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; }
I am trying to create a program in NetBeans GUI builder and I am having trouble creating the 2D array. Here is what I have come up with so far:
private void enterButtonActionPerformed(java.awt.event.ActionEvent evt) { // TODO add your handling code here: double time = 0; try{ time = Double.parseDouble(timeText.getText());
[Code] ....
Right now it is printing what i need but I need to separate columns, not rows.
Currently the while near the end is not working in netbeans. It is saying illegal start of type. This whole section was working before when it was within the public static void method. I moved it to a separate class to try and clear up a, static variable problem. My question is can i fix it to keep it structured this way. Or do I have to put it back into the main method and try to work out the static variable problem a different way.
public class InventoryProgram { double[] dvdprice; // defines variables int[] dvdnum; int[] dvdstock; String[] dvdnames; int count; double total;
