  • using java.util.Scanner to read a file byte by byte

    - by openidsucks
    I'm trying to read a one line file character by character using java.util.Scanner. However I'm getting this exception": Exception in thread "main" java.util.InputMismatchException: For input string: "contents of my file" at java.util.Scanner.nextByte(Scanner.java:1861) at java.util.Scanner.nextByte(Scanner.java:1814) at p008.main(p008.java:18) <-- line where I do scanner.nextByte() Here's my code: public static void main(String[] args) throws FileNotFoundException { File source = new File("file.txt"); Scanner scanner = new Scanner(source); while(scanner.hasNext()) { System.out.println((char)scanner.nextByte()); } scanner.close() } Does anyone have any ideas as to what I might be doing wrong? Edit: I realized I wrote hasNext() instead of hasNextByte(). However if I do that it doesn't print out anything.

  • How to detect filesystem has changed in java

    - by Alfred
    Hi all, I would like to know how to efficiently implement filesystem changes in java? Say I got a file in a folder and modify that file. I would like to be notified by java about this change as soon as possible(no frequently polling if possible.). Because I think I could call java.io.file.lastModified every few seconds but I don't like the sound of that solution at all. alfred@alfred-laptop:~/testje$ java -version java version "1.6.0_18" Java(TM) SE Runtime Environment (build 1.6.0_18-b07) Java HotSpot(TM) Server VM (build 16.0-b13, mixed mode) Many thanks, Alfred

  • using Java enums or public static fields in MATLAB

    - by Jason S
    I'm wondering how in MATLAB you can get a reference to a Java enum or static public field. In MATLAB, if you are trying to use Java objects/methods, there are equivalents to Java object creation / method call / etc.: Java: new com.example.test.Foo(); MATLAB: javaObject('com.example.test.Foo'); Java: com.example.test.Foo.staticMethod(); MATLAB: javaMethod('staticMethod', 'com.example.test.Foo'); Java: SomeEnum e = com.example.test.SomeEnum.MY_FAVORITE_ENUM; MATLAB: ????? Java: int n = com.example.test.Foo.MAX_FOO; MATLAB: ?????

  • Can I connect to SQL Server using Windows Authentication from Java EE webapp?

    - by KG
    I am currently investigating how to make a connection to a SQL Server database from my Java EE web application using Windows Authentication instead of SQL Server authentication. I am running this app off of Tomcat 6.0, and am utilizing the Microsoft JDBC driver. My connection properties file looks as follows: dbDriver = com.microsoft.sqlserver.jdbc.SQLServerDriver dbUser = user dbPass = password dbServer = localhost:1433;databaseName=testDb dbUrl = jdbc:sqlserver://localhost:1433 I have zero problems with connecting to a SQL Server database in this fashion when using SQL Server authentication. Is there any way I can retrieve the credentials of the user's Windows Authentication and use that authentication for SQL Server? UPDATE: I know in ASP.net there is a way to set up Windows Authentication for access to the webapp, which is exactly what I am looking for, except I want to pass that token off to SQL Server for access to the database.

  • Java - getClassLoader().getResource() driving me bonkers

    I have this test app: import java.applet.*; import java.awt.*; import java.net.URL; public class Test extends Applet { public void init() { URL some=Test.class.getClass().getClassLoader().getResource("/assets/pacman.png"); System.out.println(some.toString()); System.out.println(some.getFile()); System.out.println(some.getPath()); } } When I run it from Eclipse, I get the error: java.lang.NullPointerException at Test.init(Test.java:9) at sun.applet.AppletPanel.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Classpath (from .CLASSPATH file) <classpathentry kind="src" path="src"/> In my c:\project\src folder, I have only the Test.java file and the 'assets' directory which contains pacman.png.

  • java vs python. In what way is Java Better?

    - by oxinabox.ucc.asn.au
    What are the advantages of Java over Python? What are the disadvantagesof Python, over Java? Why isn't Java more like Python? Like why don't java have an command line iterpretor? I beleive Java must have some advantages, but...I'm yet to see them. Logically all languages have an advantage afaict: I learnt java before python, - a 6 month unicourse. I spend a couple of weeks using python (writting a script to make a C source file). I hated it at first (as it was so differnt from C). I realised I had fallen in love it it, when I noticed that when I went to do a follow on Java Course at uni, I'ld stopped giving my variables types, and was tryign to multiply strings.

  • Communication between java server and matlab client

    - by user272587
    I'd like to establish a server(Java)/client (Matlab) communication using socket. They can send messages to each other. An example shows how to do this in Java server and Java client, http://java.sun.com/docs/books/tutorial/networking/sockets/clientServer.html. When I try to rewrite the client part in Matlab, I only can get the first message that the Java server sends and display it in the Matlab command window. When I type a message in the Matlab command window, I can't pass it to the Java Server. Jave code: kkSocket = new Socket("localhost", 3434); Matlab equivalent: kkSocket = Socket('localhost', 3434); Java code for client: out = new PrintWriter(kkSocket.getOutputStream(), true); in = new BufferedReader(new InputStreamReader(kkSocket.getInputStream())); What would be a Matlab equivalent for this? Thanks in advance.

  • What should I learn to improve my Java skills ?

    - by hory.incpp
    Hello, I currently know Java SE and I want to learn something more 'enterprise'. I would like something more distributed (app server, server programming, web, content management system ...) but any suggestion is ok. There are many frameworks which I've heard: spring, hibernate, persistence, ejb, jsp, servlet, jsf, jboss, glassfish, ant etc etc etc etc. I'm very confused where to start. So the question is: Can somebody explain to me what actually there frameworks are; and which one should I start with ? Thank you.

  • Make a USB Device, Control It In Java

    - by yar
    I'm thinking about making a physical controller (device?) with knobs, buttons, and LEDs. I'd like to interact with it using Java (respond to the knobs, light up LEDs, etc). The reason I mention Java is two-fold: first, I know Java well1. Second, I've written the rest of the program I need to interface with in Java (though there are ways to talk to the Java program from another language). I would like the device to connect via USB and be (computer-)platform independent. I haven't the slightest idea of where to start, except to start reading the Arduino website. Is this my best/only option? Is there something better suited for communicating with Java? Note: I know that Arduino has something to do with Java (not sure what), but it seems like code must be written in a subset of C. How would I get moving on this topic? 1 - No laughter, please.

  • java.lang.NullPointerException exception in my controller file (using Spring Hibernate Maven)

    - by mrjayviper
    The problem doesn't seemed to have anything to do with Hibernate. As I've commented the Hibernate stuff but I'm still getting it. If I comment out this line message = staffDAO.searchForStaff(search); in my controller file, it goes through ok. But I don't see anything wrong with searchForStaff function. It's a very simple function that just returns the string "test" and run system.out.println("test"). Can you please help? thanks But this is the error that I'm getting: SEVERE: Servlet.service() for servlet [spring] in context with path [/directorymaven] threw exception [Request processing failed;

  • "state is undetermined" when starting Grails app on CloudFoundry

    - by SeattleStephens
    I have a Grails app that has been running on CloudFoundry for months. I updated the app from Grails 2.0.4 to 2.1.0 and also updated a few plugins I have been using.

  • Problem with Java Mail : No provider for smtp

    - by user359198
    Hello all. I am using JavaMail to do a simple application that sends an email when it finds some files in a directory. I managed to get it worked from Eclipse. I Run the application and it sent the email with no errors. But, when I created the jar, and executed it, it fails in the email sending part. It gives this exception. javax.mail.NoSuchProviderException: No provider for smtp at javax.mail.Session.getProvider(Session.java:460) at javax.mail.Session.getTransport(Session.java:655) at javax.mail.Session.getTransport(Session.java:636) at main.java.util.MailManager.sendMail(MailManager.java:69) at main.java.DownloadsMail.composeAndSendMail(DownloadsMail.java:16) at main.java.DownloadsController.checkDownloads(DownloadsController.java:51) at main.java.MainDownloadsController.run(MainDownloadsController.java:26) at java.lang.Thread.run(Unknown Source) I am using the library in this method: public static boolean sendMail(String subject, String text){ noExceptionsThrown = true; try { loadProperties(); } catch (IOException e1) { System.out.println("Problem encountered while loading properties"); e1.printStackTrace(); noExceptionsThrown = false; } Properties mailProps = new Properties(); String host = "mail.smtp.host"; mailProps.setProperty(host, connectionProps.getProperty(host)); String tls = "mail.smtp.starttls.enable"; mailProps.setProperty(tls, connectionProps.getProperty(tls)); String port = "mail.smtp.port"; mailProps.setProperty(port, connectionProps.getProperty(port)); String user = "mail.smtp.user"; mailProps.setProperty(user, connectionProps.getProperty(user)); String auth = "mail.smtp.auth"; mailProps.setProperty(auth, connectionProps.getProperty(auth)); Session session = Session.getDefaultInstance(mailProps); //session.setDebug(true); MimeMessage message = new MimeMessage(session); try { message.setFrom(new InternetAddress(messageProps.getProperty("from"))); message.addRecipient(Message.RecipientType.TO, new InternetAddress( messageProps.getProperty("to"))); message.setSubject(subject); message.setText(text); Transport t = session.getTransport("smtp"); try { t.connect(connectionProps.getProperty("user"), passwordProps .getProperty("password")); t.sendMessage(message, message.getAllRecipients()); } catch (Exception e) { System.out.println("Error encountered while sending the email"); e.printStackTrace(); noExceptionsThrown = false; } finally { t.close(); } } catch (Exception e) { System.out.println("Error encountered while creating the message"); e.printStackTrace(); noExceptionsThrown = false; } return noExceptionsThrown; } I am loading these values from properties files. mail.smtp.host=smtp.gmail.com mail.smtp.starttls.enable=true mail.smtp.port=587 mail.smtp.auth=true I have tried to change the host by ssl://smtp.gmail.com, the port by 465 (just for trying something different), but it doesn't work either. Anyway, if it works fine from Eclipse with the original parameters, I guess that the values are correct, but the problem is creating the jar. I don't know very much about the possible results or changes when creating a jar. Could the JavaMail libraries someway go wrong when the jar is created? Do you have any ideas? Thank you very much for your help.

  • Making a app show inside a GUI in Java

    - by José
    Hello. I have one problem I've been dealing with for this week. You see, I'm new to Java, so that's probably it... Anyways, I've started a project out of pure curiosity. I had it done in Java, but in plain CMD-style, which is not very pretty. It calls one of my ten programs, chosen by the user using "Case". Eg.: If you type 1, it will go to program 1. After you finish it, it goes back to selection until the user press 0. After that, I've been trying to make a GUI for it. I've been able to create the selector alone and make it respond to the numbers chosen. If you press 1 and click ok, it will tell you you've chosen program 1. I, however, have not been able to make it run the program. I've been trying to make the program show up in a jPanel, part of the main GUI. I failed miserably. The program runs in separate but I can't make them run together like the CMD one. The apps were made in Eclipse SDK 3.5.2 The GUIs were made in Netbeans IDE 6.8 Here's the code for the GUI only (the prints are in PT-BR, my native language): Main program: /* * To change this template, choose Tools | Templates * and open the template in the editor. */ /* * ProgramasGUI.java * * Created on 31/01/2010, 22:56:19 */ package Main; import Main.Prog1; /** * * @author Zeh® */ public class ProgramasGUI extends javax.swing.JFrame { /** Creates new form ProgramasGUI */ public ProgramasGUI() { initComponents(); } /** This method is called from within the constructor to * initialize the form. * WARNING: Do NOT modify this code.

  • How to use Java on Google App Engine without exceeding minute quotas?

    - by Geo
    A very simple java code inside a doGet() servlet is getting more than a second of cpu time on GAE. I have read some quota related documentation and apparently I am not doing anything wrong. //Request the user Agent info String userAgent = req.getHeader("User-Agent"); I wanted to know what was using the CPU the most, I use a google help recommendation. //The two lines below will get the CPU before requesting User-Agent Information QuotaService qs = QuotaServiceFactory.getQuotaService(); long start = qs.getCpuTimeInMegaCycles(); //Request the user Agent info String userAgent = req.getHeader("User-Agent"); //The three lines below will get the CPU after requesting User-Agent Information // and informed it to the application log. long end = qs.getCpuTimeInMegaCycles(); double cpuSeconds = qs.convertMegacyclesToCpuSeconds(end - start); log.warning("CPU Seconds on geting User Agent: " + cpuSeconds); The only thing that the code above tells me is that inspecting the header will use more than a second (1000ms) of cpu time, which for Google is a warning on the log panel. That seems to be a very simple request and still is using more than a second of cpu. What I am missing?
