  • Writing low latency Java

    - by user997112
    Are there any Java-specific techniques (things which wouldnt apply to C++) for writing low latency code, in Java? I often see Java low latency roles and they ask for experience writing low latency Java- which sometimes seems a little bit of an oxymoron. The only think I could think of is experience with JNI, outsourcing I/O calls to native code. Also possibly using the disruptor pattern, but thats not an actual technology. Are there any Java specific tips for writing low latency code? I am aware there is a Real Time Java Spec, but I have been warned real-time is not the same as low latency....

  • Is Java free/open source or not?

    - by user1598390
    On November 13, 2006, Sun released much of Java as free and open source software, (FOSS), under the terms of the GNU General Public License (GPL). On May 8, 2007, Sun finished the process, making all of Java's core code available under free software/open-source distribution terms, aside from a small portion of code to which Sun did not hold the copyright. OpenJDK (Open Java Development Kit) is a free and open source implementation of the Java programming language. It is the result of an effort Sun Microsystems began in 2006. The implementation is licensed under the GNU General Public License (GNU GPL) with a linking exception. Why there are still people that say Java is not open source or free as in free speech ? Am I missing something? Is Java still privative ?

  • Whats the best way of learning how to Develop Java Games

    - by Shaun
    As the Title says, the question is Whats the best way of learning how to Develop Java Games? Indeed there's over thousands of tutorials explaining and teaching you the basic's of Java and how It works but they are usually and majority of the tutorial's teaching you Java basic's are boring and don't push you as you could do. Basically, is there any tutorials out there that push you so and give you problems you have to solve and push your knowledge so you get a much better understanding of creating java games. This seems a ideal question for new people learning Java and hopefully should help newbie's learning Java. (Sorry if this sounds noobish).

  • Project Jigsaw: On the next train

    - by Mark Reinhold
    I recently proposed to defer Project Jigsaw from Java 8 to Java 9. Feedback on the proposal was about evenly divided as to whether Java 8 should be delayed for Jigsaw, Jigsaw should be deferred to Java 9, or some other, usually less-realistic, option should be taken. The ultimate decision rested, of course, with the Java SE 8 (JSR 337) Expert Group. After due consideration, a strong majority of the EG agreed to my proposal. In light of this decision we can still make progress in Java 8 toward the convergence of the higher-end Java ME Platforms with Java SE. I previously suggested that we consider defining a small number of Profiles which would allow compact configurations of the SE Platform to be built and deployed. JEP 161 lays out a specific initial proposal for such Profiles. There is also much useful work to be done in Java 8 toward the fully-modular platform in Java 9. Alan Bateman has submitted JEP 162, which proposes some changes in Java 8 to smooth the eventual transition to modules, to provide new tools to help developers prepare for modularity, and to deprecate and then, in Java 9, actually remove certain API elements that are a significant impediment to modularization. Thanks to everyone who responded to the proposal with comments and questions. As I wrote initially, deferring Jigsaw to a Java 9 release in 2015 is by no means a pleasant decision. It does, however, still appear to be the best available option, and it is now the plan of record.

  • JOGL: cannot run java on compiled class file

    - by John Goche
    I am running ubuntu Linux 11.10. I have followed the instructions on the site http://jogamp.org/jogl/www/ and downloaded everything with git to $HOME/jogamp and built everything with ant (although I would have prefered the files installed somewhere under /usr/local). I am trying to run a simple application with JOGL found on the Wikipedia site: http://en.wikipedia.org/wiki/Java_OpenGL In order to compile the file I had to add: export CLASSPATH.:$HOME/jogamp/jogl/build/jogl/classes in order to compile the code.

  • Java Scanner - next String until a | is found

    - by user1375883
    Currently I'm trying to read through some basic cells, in this format: +-------+-------+ | | | +-------+-------+ Now I need to get the string representation of the cell's contents and send it off to another method. The problem is that the cells have no pre-defined length. I'm reading these from a file, so my easiest option should be to just use the Scanner I already have set up. Problem is, I don't really know how for this case. I have a strong feeling that I need to use the pattern somehow, but I'm at a complete loss on how to do it. I could also probably just build it up somehow, but that strikes me as being painfully slow.

  • Upgrading to Java 7u65 breaks my Deployment Rule Set for Oracle applications

    - by Don Atreides
    My company uses an older version of an Oracle application that requires Java 6u45. Naturally we want to be secure, so we use a Deployment Rule Set to specify 6u45 for that internal application and let other applications use 7u60. Now that we're ready to upgrade the Java 7 half to 7u67, the Oracle application breaks with "Deployment Rule Set required version 1.6.0_45 not available." Of course it is available, it just can't find it for some reason. As a test, I specified that JavaTester.org should use 6u45 also and it works fine with no issues. But when I try to use the same configuration (7u67 and 6u45) against the Oracle application it fails every time. If I downgrade to 7u60, it works. 7u65 or higher, it breaks. The Oracle application hasn't changed so it must be something different in how 7u65+ is handling Deployment Rule Sets or pathing or something. I'm at a complete loss. ruleset.xml: <?xml version="1.0"?> -<ruleset version="1.0+"> -<rule> <id location="*.mycorp.com"/> <action version="1.6.0_45" permission="run"/> </rule> -<rule> <id location="http://javatester.org"/> <action version="1.6.0_45" permission="run"/> </rule> </ruleset>

  • Error accessing a Web Service with SSL

    - by Elie
    I have a program that is supposed to send a file to a web service, which requires an SSL connection. I run the program as follows: SET JAVA_HOME=C:\Program Files\Java\jre1.6.0_07 SET com.ibm.SSL.ConfigURL=ssl.client.props "%JAVA_HOME%\bin\java" -cp ".;Test.jar" ca.mypackage.Main This was works fine, but when I change the first line to SET JAVA_HOME=C:\Program Files\IBM\SDP\runtimes\base_v7\java\jre I get the following error: com.sun.xml.internal.ws.client.ClientTransportException: HTTP transport error: java.net.SocketException: java.lang.ClassNotFoundException: Cannot find the specified class com.ibm.websphere.ssl.protocol.SSLSocketFactory at com.sun.xml.internal.ws.transport.http.client.HttpClientTransport.getOutput(HttpClientTransport.java:119) at com.sun.xml.internal.ws.transport.http.client.HttpTransportPipe.process(HttpTransportPipe.java:140) at com.sun.xml.internal.ws.transport.http.client.HttpTransportPipe.processRequest(HttpTransportPipe.java:86) at com.sun.xml.internal.ws.api.pipe.Fiber.__doRun(Fiber.java:593) at com.sun.xml.internal.ws.api.pipe.Fiber._doRun(Fiber.java:552) at com.sun.xml.internal.ws.api.pipe.Fiber.doRun(Fiber.java:537) at com.sun.xml.internal.ws.api.pipe.Fiber.runSync(Fiber.java:434) at com.sun.xml.internal.ws.client.Stub.process(Stub.java:247) at com.sun.xml.internal.ws.client.sei.SEIStub.doProcess(SEIStub.java:132) at com.sun.xml.internal.ws.client.sei.SyncMethodHandler.invoke(SyncMethodHandler.java:242) at com.sun.xml.internal.ws.client.sei.SyncMethodHandler.invoke(SyncMethodHandler.java:222) at com.sun.xml.internal.ws.client.sei.SEIStub.invoke(SEIStub.java:115) at $Proxy26.fileSubmit(Unknown Source) at com.testing.TestingSoapProxy.fileSubmit(TestingSoapProxy.java:81) at ca.mypackage.Main.main(Main.java:63) Caused by: java.net.SocketException: java.lang.ClassNotFoundException: Cannot find the specified class com.ibm.websphere.ssl.protocol.SSLSocketFactory at javax.net.ssl.DefaultSSLSocketFactory.a(SSLSocketFactory.java:7) at javax.net.ssl.DefaultSSLSocketFactory.createSocket(SSLSocketFactory.java:1) at com.ibm.net.ssl.www2.protocol.https.c.afterConnect(c.java:110) at com.ibm.net.ssl.www2.protocol.https.d.connect(d.java:14) at sun.net.www.protocol.http.HttpURLConnection.getOutputStream(HttpURLConnection.java:902) at com.ibm.net.ssl.www2.protocol.https.b.getOutputStream(b.java:86) at com.sun.xml.internal.ws.transport.http.client.HttpClientTransport.getOutput(HttpClientTransport.java:107) ... 14 more Caused by: java.lang.ClassNotFoundException: Cannot find the specified class com.ibm.websphere.ssl.protocol.SSLSocketFactory at javax.net.ssl.SSLJsseUtil.b(SSLJsseUtil.java:20) at javax.net.ssl.SSLSocketFactory.getDefault(SSLSocketFactory.java:36) at javax.net.ssl.HttpsURLConnection.getDefaultSSLSocketFactory(HttpsURLConnection.java:16) at javax.net.ssl.HttpsURLConnection.<init>(HttpsURLConnection.java:36) at com.ibm.net.ssl.www2.protocol.https.b.<init>(b.java:1) at com.ibm.net.ssl.www2.protocol.https.Handler.openConnection(Handler.java:11) at java.net.URL.openConnection(URL.java:995) at com.sun.xml.internal.ws.api.EndpointAddress.openConnection(EndpointAddress.java:206) at com.sun.xml.internal.ws.transport.http.client.HttpClientTransport.createHttpConnection(HttpClientTransport.java:277) at com.sun.xml.internal.ws.transport.http.client.HttpClientTransport.getOutput(HttpClientTransport.java:103) ... 14 more So it seems that this problem would be related to the JRE I'm using, but what doesn't seem to make sense is that the non-IBM JRE works fine, but the IBM JRE does not. Any ideas, or suggestions?

  • Joystick input in Java

    - by typoknig
    Hi all, I am making a 2D game in Java and I want to use a joystick to control the movement of some crosshairs. Right now I have it so the mouse can control those crosshairs. My only criteria for this is that the control for the crosshair must stay in the game window unless a user clicks off into another window. Basically I want my game to capture whatever device is controlling the crosshairs much like a virtual machine captures a mouse. The joystick I am using (Thrustmaster Hotas Cougar) comes with some pretty advanced features, so that may make this easier (or harder). I have tried the solution listed on this page, but I am using a 64bit computer and for some reason it does not like that. I have also tried to use the key emulation feature of my joystick, but with little success. Here is what I have so far, any pointer would be appreciated. Main Class: import java.awt.Color; import java.awt.Cursor; import java.awt.event.MouseEvent; import java.awt.event.MouseMotionListener; import java.awt.Graphics; import java.awt.Image; import java.awt.image.BufferStrategy; import java.awt.image.MemoryImageSource; import java.awt.Point; import java.awt.Toolkit; import javax.swing.JFrame; public class Game extends JFrame implements MouseMotionListener{ private int windowWidth = 1280; private int windowHeight = 1024; private Crosshair crosshair; public static void main(String[] args) { new Game(); } public Game() { this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); this.setSize(windowWidth, windowHeight); this.setResizable(false); this.setLocation(0,0); this.setVisible(true); this.createBufferStrategy(2); addMouseMotionListener(this); initGame(); while(true) { long start = System.currentTimeMillis(); gameLoop(); while(System.currentTimeMillis()-start < 5) { //empty while loop } } } private void initGame() { hideCursor(); crosshair = new Crosshair (windowWidth/2, windowHeight/2); } private void gameLoop() { //game logic drawFrame(); } private void drawFrame() { BufferStrategy bf = this.getBufferStrategy(); Graphics g = (Graphics)bf.getDrawGraphics(); try { g = bf.getDrawGraphics(); Color darkBlue = new Color(0x010040); g.setColor(darkBlue); g.fillRect(0, 0, windowWidth, windowHeight); drawCrossHair(g); } finally { g.dispose(); } bf.show(); Toolkit.getDefaultToolkit().sync(); } private void drawCrossHair(Graphics g){ Color yellow = new Color (0xEDFF62); g.setColor(yellow); g.drawOval(crosshair.x, crosshair.y, 40, 40); g.fillArc(crosshair.x + 10, crosshair.y + 21 , 20, 20, -45, -90); g.fillArc(crosshair.x - 1, crosshair.y + 10, 20, 20, -135, -90); g.fillArc(crosshair.x + 10, crosshair.y - 1, 20, 20, -225, -90); g.fillArc(crosshair.x + 21, crosshair.y + 10, 20, 20, -315, -90); } @Override public void mouseDragged(MouseEvent e) { //empty method } @Override public void mouseMoved(MouseEvent e) { crosshair.x = e.getX(); crosshair.y = e.getY(); } private void hideCursor() { int[] pixels = new int[16 * 16]; Image image = Toolkit.getDefaultToolkit().createImage(new MemoryImageSource(16, 16, pixels, 0, 16)); Cursor transparentCursor = Toolkit.getDefaultToolkit().createCustomCursor(image, new Point(0, 0), "invisiblecursor"); getContentPane().setCursor(transparentCursor); } } Another Class: public class Crosshair{ public int x; public int y; public Crosshair(int x, int y) { this.x = x; this.y = y; } }

  • Spring/RMI server error

    - by 4herpsand7derpsago
    We have a Spring MVC web app (WAR) deploying to Tomcat (6.0.35) that launches a thread inside a separate JVM at deploy time (don't ask why - not my design) and then communicates with that thread via RMI over port 8888. Despite being totally convoluded, this was working perfectly fine up until yesterday, and now the thread is failing at startup and despite our best efforts to add logging into the mix, we are hitting a wall. This is the only exception we are able to find in the logs: Jun 12, 2012 3:11:36 AM com.ourapp.ImageController destroy SEVERE: Shutdown Error: Lookup of RMI stub failed; nested exception is java.rmi.ConnectException: Connection refused to host: localhost; nested exception is: java.net.ConnectException: Connection refused Jun 12, 2012 3:11:37 AM org.apache.catalina.core.StandardContext listenerStop SEVERE: Exception sending context destroyed event to listener instance of class org.springframework.web.context.ContextLoaderListener java.lang.NoClassDefFoundError: org/springframework/web/context/ContextCleanupListener at org.springframework.web.context.ContextLoaderListener.contextDestroyed(ContextLoaderListener.java:80) at org.apache.catalina.core.StandardContext.listenerStop(StandardContext.java:3973) at org.apache.catalina.core.StandardContext.stop(StandardContext.java:4577) at org.apache.catalina.startup.HostConfig.checkResources(HostConfig.java:1165) at org.apache.catalina.startup.HostConfig.check(HostConfig.java:1271) at org.apache.catalina.startup.HostConfig.lifecycleEvent(HostConfig.java:296) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:119) at org.apache.catalina.core.ContainerBase.backgroundProcess(ContainerBase.java:1337) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.processChildren(ContainerBase.java:1601) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.processChildren(ContainerBase.java:1610) at org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor.run(ContainerBase.java:1590) at java.lang.Thread.run(Thread.java:662) Caused by: java.lang.ClassNotFoundException: org.springframework.web.context.ContextCleanupListener at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1387) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1233) ... 12 more The ImageController is the Spring MVC Controller that is responsible for kicking off this daemon/spawned RMI thread. Based on the verbage of this error, does anybody have any idea what might be causing this "connection refused" error? Running a netstat -an | grep 8888 (this is a Linux machine) produces no output which means nothing is listening on that port. Thanks in advance for any ideas/suggestions that lead to a fix.

  • Web services, Java EE, Spring, DB integration project ideas - maybe data mining related?

    - by saral jain
    I am a graduate Computer Science student (Data Mining and Machine Learning) and have good exposure to core Java (3 years). I have read up on a bunch of stuff on the following topics: Design patterns, Java EE Web services (SOAP and REST), Spring, and Hibernate Java Concurrency - advanced features like Task and Executors. I would now like to do a project combining this stuff -- over my free time of course -- to get a better understanding of these things and to kind of make an end to end software (to learn the best design principles etc + SVN, maven). Any good project ideas would be really appreciated. I just want to build this stuff to learn, so I don't really mind re-inventing the wheel. Also, anything related to data mining would be an added bonus as it fits with my research but is absolutely not necessary since this project is more to learn to do large scale software development.

  • Java: implementation of simple commands

    - by HH
    I have created a pkg for my regular simple commands. They are non-static, to be more extensible, but somewhat more time-consuming to use because of creating object to use one. My other classes use them. $ ls *.java CpF.java IsBinary.java RmLn.java Tools.java F2S.java IsRoot.java SaveToDisk.java WordCount.java Filters.java ModRelativePaths.java SetWord.java WordNumber.java Find.java powerTools.java Sort.java Which option would you choose to use them easier? to develop a small interface like 'powerTools.java' for the pkg. to create a class with static methods for them. to add a static method to each class to stop overusing 'creating too many files' and centralising some? sthing else?
