I am trying to make java application that counts number of prints for a document by user. let say user login to the program , he selects and prints one document, the program will register this print for this document by this user .Next time if the same user prints the same document , it will count second time , third time and so on. The problem here is that you cannot depend on  job.print(myDoc, aset) because not every job of printing will print the document, because simply the printer is either off , door open, no papers , or even the job itself on queue.  I have searched a lot I could not find how to make the printer responds back if the document is printed in java.  I have tried with PrinterStateReasons and I have tried with PrintJobWatcher class but no ways at all. how I will make sure the document is printed by the user.

*all my documents are in one copy only.

please help me how to do this.
here is my code
import java.io.ByteArrayInputStream; import java.io.IOException; import java.io.InputStream; import java.io.File; import java.io.FileInputStream; import javax.print.Doc; import javax.print.DocFlavor; import javax.print.DocPrintJob; import javax.print.PrintException; import javax.print.PrintService; import javax.print.PrintServiceLookup; import javax.print.SimpleDoc; import javax.print.attribute.HashPrintRequestAttributeSet; import javax.print.attribute.PrintRequestAttributeSet; import javax.print.attribute.standard.Copies; import javax.print.event.PrintJobAdapter; import javax.print.event.PrintJobEvent; public class PrintTextFile {  public static void main(String[] args) throws PrintException, IOException {     FileInputStream inputFileStream = new FileInputStream(new File("test.pdf"));      String defaultPrinter = PrintServiceLookup.lookupDefaultPrintService().getName();    System.out.println("Default printer: " + defaultPrinter);    //PrintService service = PrintServiceLookup.lookupDefaultPrintService();                    PrintRequestAttributeSet  pras = new HashPrintRequestAttributeSet();    pras.add(new Copies(1));    DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;    Doc doc = new SimpleDoc(inputFileStream, flavor, null);        PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();    PrintService[] services = PrintServiceLookup.lookupPrintServices(flavor, aset);        PrintService myPrinter = null;        for (int i = 0; i < services.length; i++){                        String svcName = services[i].toString();                  System.out.println("service found: "+svcName);                if (svcName.contains("HP Printer")){                myPrinter = services[i];                System.out.println("my printer found: "+svcName);                break;            }        }    DocPrintJob job = myPrinter.createPrintJob();    PrintJobWatcher pjw = new PrintJobWatcher(job);    job.print(doc, pras);    pjw.waitForDone();    inputFileStream.close();    // send FF to eject the page    InputStream ff = new ByteArrayInputStream("\f".getBytes());    Doc docff = new SimpleDoc(ff, flavor, null);    DocPrintJob jobff = myPrinter.createPrintJob();    pjw = new PrintJobWatcher(jobff);    jobff.print(docff, null);    pjw.waitForDone();  } } class PrintJobWatcher {  boolean done = false;  PrintJobWatcher(DocPrintJob job) {    job.addPrintJobListener(new PrintJobAdapter() {      public void printJobCanceled(PrintJobEvent pje) {        allDone();      }      public void printJobCompleted(PrintJobEvent pje) {        allDone();      }      public void printJobFailed(PrintJobEvent pje) {        allDone();      }      public void printJobNoMoreEvents(PrintJobEvent pje) {        allDone();      }      void allDone() {        synchronized (PrintJobWatcher.this) {          done = true;          System.out.println("Printing done ...");          PrintJobWatcher.this.notify();        }      }    });  }  public synchronized void waitForDone() {    try {      while (!done) {        wait();      }    } catch (InterruptedException e) {    }  } }

I have seen the code and explanation of printing PDF in java using DocPrintJob and PrintService here in this link. I am just wondering if the code can print a PDF document of different sizes. How about if the selected printer  according to below code is not able to print the PDF format of different sizes say A3 ,A5, because the printer is only printing paper size A4 what will happen in this case
PrintService myPrinter = null;        for (int i = 0; i < services.length; i++){            System.out.println("service found: "+svcName);            String svcName = services[i].toString();                      if (svcName.contains("selectedPrinterName")){                myPrinter = services[i];                System.out.println("my printer found: "+svcName);                break;            }        }

is there a way to print pdf pages automatically according to the page size ?. How to determine page size of type A3,A4,A5,...etc of pdf page . Is there a way if I got the page size of pdf page I can print that page in the appropriate format ?
please help me I am really confused.
thank you in advance

I have one jsp form that it has upload file input. The file is being uploaded to the servlet and servlet is reading the file successfully. The servlet is processing the data of file doing some stuff after reading the file. for me I can't assume how much time the servlet is going to take because as I told servlet is processing data of the file so it might be big data with other files and will take longer time. what I need is I want to show to user such progress bar that indicates to him the server is busy processing the uploaded file.  how is that ? anyone can help me please.

And what security problems would exist if the purchaser had the source code to your servlets? What assets of yours would be damaged or lost in that case?

. simply he can change the code or adjust it to what he needs and sell it to others as he is the owner of the program.

I undertsand of what you are saying about viewing the source code , but I have seen some web applications done in ASP that you cannot inspect the html element to view the source code . why I am trying to do that because I don't want anyone who is having an idea about JSP can find my servlets and do sql injection or whatever. how these people disable this functionality from web browser.

since the end user will never get to see the class files then there's nothing you need to concern yourself about with that

actually I am trying to sell my web application and distribute it so for that how can I secure my java classes from being retrieved to original source code. I have tried to use ProGuard and then check the classes after obfuscation process , it returns back with little bit change so someone if he set on it he can analyze and understand the code again. specially I cannot change the name of servlet classes because I need to link it to web.xml as below
<servlet> <description> this to the login page </description> <display-name>this is for login servlet</display-name> <servlet-name>loginServlet</servlet-name> <servlet-class> projectPackage.LoginServlet </servlet-class> </servlet>      <servlet-mapping> <servlet-name>loginServlet</servlet-name> <url-pattern>/loginServlet</url-pattern> </servlet-mapping>
here I don't want to obfuscate the "loginServlet" name to be xxx because "loginServlet" in my login form will not be exist any more.
please help me on this , how to secure my java servlet classes.

Hi experts , assume you create a web jsp application and now you want to make it online. how to secure or protect your web application like disable viewing source code or make it only running in Microsoft explorer with no toolbar options ( F2 is disabled and inspect element is also disabled). how also encrypt the servlet classes so no decompile java classes can be occurred. I want to know how much security I can achieve fro my application.

thanks a lot I will try that

Hi all , if I want to develop GUI application with fantastic interactive interface . I am good in java swing but when I see my friends creating their GUI applications using VB.net which is better than what I can do in java, even though both programs are functionally perfect and do the same job.   My question is do I have to learn VB.net for designing and creating good GUI application or I have to read a lot in how to design in java swing.

Hi experts, I have a JSP system I create for my company. It is like a library system . I need now to include the web mail system so users can exchange information among them easily inside the library system. it can do same as outlook , user  send , receive , & forward mails. why I need it in my application although I can use outlook mail as my alternative ? because I need users only exchange information about the library system no other subjects and I can track all users mail.
