Generating Printout File And Sending It To Printer
Mar 29, 2014
I am designing simple app which would store data about users and generate standard letter and print sun ray card for this user. I know how to build UI, how to validate it etc. I know how to store data in database, but I don't know how to deal printing.
I have MS doc template documents they contain jpg pictures, and unusual formatting Is there a way of actually pulling those templates and do the merge and perform print operation? If it is not easily done, what else I could do? I would need to have option to easily edit those templates in case of any changes.

Am facing a very strange issue. While trying to compile a very simple Hello World java program, the compilation completes successfully without any error or warning, but it does not generate the class file.
It happens when I compile with a particular jar file, otherwise compiling only the program (or with any other jar) does generate the class file. I am using java 1.7.0_45.

I have two programs that I'll post below, one is a Server and the other is a Client. The ChatServer runs once and many clients can run ChatClient from separate computers and talk together in their GUI's. The the client program comes with two buttons, one that's simulates the sending of a message to a single user ; "Send Message To User", and one that just generally sends a message ; "Send Message To All". Although now the Clients on the server seem to be able to selectively send messages to an individual by giving the recipient name, all the clients can see that message, which is not exact what I am aiming for. What I am going for is having the "Send Message To User" button click to send a message to the named user without all other users seeing the message.
The Server Program Code
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.ArrayList;
[Code] ....
Now I have tried thing like having various input output streams and trying to connect those, but no luck. Tried fiddling with having the names arraylist directing the messages to one client versus all but that did not work out either. How I what I would need to do to go about doing this?

Well I want to generate a license key for my software product. I'm aware of Google's Guava Libraries for generating alpha numeric license keys. But I'm thinking it to do in a different way without using any such libraries or specifically guava libraries. Till now this is my plan that,
1. Get a MAC ID / IP Address of the system in which the application will be installed and ready for it's first use.
2. Store that MAC ID in a UNCOMMON File format in client's PC only.
3. And what should be the next step.?

When you "system.out.print(arraylist)" an arraylist, it will give you something like [item1, item2].
Im wondering how I can remove the "[" and "]" brackets fromt he printout, or even if i pass it in as another variable.

I have an application and I would like it to send a file to a web page using POST method.
I've found the HttpClient from Apache, but I had no luck. All the tutorials and samples I can find on the net are for 3.x. I've tried adopting the samples with the HttpClient 4.1 docs, but I failed.
I have a target url of a page and source file path. I get the basic idea of what needs to happen, I am just finding it hard to implement it.

I am working on some enhancement on application. I have a requirement. The flow is as below
In a jsp file one selection dropdown exists and a body. Selection dropdown is written as custom tag library and is included in jsp file eg tag.tld whose code exists in tag.java code for other parts of jsp are written in that *.jsp file itself. eg test.jsp
i.e test.jsp calls tag.tld to include selection dropdown
I now want a hashmap created in tag.java to be available in jsp file and I want to use it in one of the javascript function available in same jsp file for validation
How can I achieve this....

I 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.

I 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!

I'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.

My project is writing a program that generates a series of numbers to appear like a social security number (XXX-XX-XXXX). My code runs.. But any number below 10 it just shows one number (XXX-X-XXXX). What do I need to enter in to my code so that if the number is <10 it will show (00,01,02,03....)?
Java Code:
import java.util.Random;
public class IDnumber
{
public static void main (String[] args) {
Random generator = new Random()
int num1 = (generator.nextInt(7) + 1) * 100 + (generator.nextInt(8) * 10) + generator.nextInt(8);
int num2 = generator.nextInt(74);
int num3 = generator.nextInt(10000);
String IDnumber = num1 + "-" + num2 + "-" + num3;
System.out.println(IDnumber);
}
} mh_sh_highlight_all('java');
