Use JAVA In Oracle To Send Blob To Printer?
Sep 18, 2014I used the PLPDF software to generate a blob in PDF format in PL/SQL. I can open it in a browser but I would rather send it directly to a printer from PL/SQL.
I know I can use tools like BI and Jasper but I want this particular solution to be 100% database solution.
I was wondering of I can use JAVA in Oracle to send the blob to a printer.
Java 1.8 - Rendering Images To Printer / Result Is Not Good
Feb 10, 2015I have some troubles rendering images to the printer, any resolution does not work, even 72 in PDF printer does not work, the image is crappy.
I use the following code but the result is not good. I mean the image quality is not acceptable.
img=new ImageIcon("c:\test\m.jpg").getImage();
scale=72/300d;
g.scale(scale,scale);
g.drawImage(img, 0, 0, (int) (img.getWidth(null)/scale), (int) (img.getHeight(null)/scale), null);
I've also tried :
img=new ImageIcon("c:\test\m.jpg").getImage();
AffineTransform aft=g.getTransform();
double scale=aft.getScaleX();
g.scale(scale,scale);
g.drawImage(img, 0, 0, (int) (img.getWidth(null)/scale), (int) (img.getHeight(null)/scale), null);
The result is the same even if I change the image, very poor and unacceptable!
How To Print PDF In Java - Send Document To Printer Upon User Request
Apr 24, 2008I've been googling information on how to print a pdf in java, and it seems that the java print api is used more for printing from a swing app. What I'm needing to do is send a pdf document to the printer upon user request. I would like my app to work as follows - User selects pdf to be printed- Program determines pages to be printed and deducts amount from user account- If sufficient money, program sends job to printer automatically without popping up the print screen.- If printed successfully, then program tells user it was printed. I'm able to figure out the rest of the pieces, in regards to user input and determining pages of the pdf, except I don't see how I will be able to print the pdf.
I've tried to use this code
PrintService defaultPrintService = PrintServiceLookup.lookupDefaultPrintService();
DocPrintJob printerJob = defaultPrintService.createPrintJob();
File pdfFile = new File("c://myPdf.pdf");
SimpleDoc simpleDoc = null;
try {
simpleDoc = new SimpleDoc(pdfFile.toURL(), DocFlavor.URL.AUTOSENSE, null);
[Code] ....
But all that I get is junk characters spread across 15 or so pages, for a pdf file that simply says "Hello World". I can open the pdf file on my computer, and print it ok, but when using the above code, it just prints out junk. How I might need to format or setup the pdf so that I can print it correctly. My program could be run on any number of Linux systems, with a multitude of printer types.
How To Get Size Of Array From Textfile
Feb 15, 2015I have the textfile which has lines:
A B 2 midterm 100
C D 1 final 90
C D 1 midterm 90
A B 2 final 80
**NO ARRAYLIST IS ALLOWED!** And the textfile is passed into the method. How to get the size for the array non-randomly inside the method from the passed Scanner file?? What if you have lots of numbers of lines, so how could that be done?
I have doubts about this line Exam[] object = new Exam[12];

DAO Based Application - Replacing Old Textfile
Apr 16, 2014I'm currently trying to build a DAO based application where you use a text file as a data source. It have worked out well until I tried to delete lines from the file.
public void delete(DTOBil dtobil) {
try{
reader = Files.newBufferedReader(Paths.get("databilar.txt"),charset);
writer = Files.newBufferedWriter(Paths.get("temp.txt"), charset, StandardOpenOption.CREATE_NEW);
String line = null;
while((line = reader.readLine()) != null){
[Code] ....
I've managed to fill out the temp file with everything except the line I wanted to remove, but when I try to replace the original file with the temp file it won't work. It casts the error: "temp.txt -> databilar.txt".
I've also tried to use the renameTo method without any success...

Java Loses Focus When Printing
Aug 1, 2014I am working on a Java program to monitor meal consumption by members of an organization. They swipe their ID cards, enter PIN, and number of meals they want. System knows if dining room is open and what meal based on time. The system then prints out a receipt on an Epson TM-T88IV receipt printer.
The system is running in console mode. My problem is that when the system prints, a Notepad window pops up for milliseconds and then the Java program loses focus. The screen reverts back to Windows home screen. I'm using Windows XP, SP3 and the latest Java build.
How to prevent the loss of focus?
