  • A Huge Opportunity in Small Things

    - by Tori Wieldt
    Addressing the strong demand for Java in the embedded market, Oracle is hosting a new Java Embedded @ JavaOne event in San Francisco October 3-4. The event allows decision makers to attend the Java Embedded @ JavaOne business-focused program, while their IT/development staff can attend the technically-focused JavaOne conference. [Obligatory comment about suits & ties vs. jeans & T-shirts removed.] The two-day event includes keynotes, sessions and demonstrations. In his keynote this morning, Judson Althoff, Senior Vice President of Worldwide Alliances and Channels and Embedded Sales, Oracle explained  Devices are all around us - on 24x7, connected all the time. The explosion of devices is the next IT revolution. Java is the right solution for this space. Java embedded solutions provide a framework to  provision, manage, and secure devices.  Java embedded solutions also provide the ability to aggregate, process and analyze multitude of data.  Java is one platform to program them all. Terrance Barr, Java Evangelist and Java ME expert is enthusiastic about the huge opportunity, "It's the right time and right place for Java Embedded," he said, "Oracle is looking for partners who want to take advantage of this next wave in IT." The Embedded space continues to heat up. Today, Cinterion launched the EHS5, an ultra compact, high-speed M2M communication module providing secure wireless connectivity for a wide variety of industrial applications. Last week, Oracle announced Oracle Java ME Embedded 3.2, a complete client Java runtime Optimized for resource-constrained, connected, embedded systems, Oracle Java Wireless Client 3.2, Oracle Java ME Software Development Kit (SDK) 3.2, and Oracle Java Embedded Suite 7.0 for larger embedded devices. There is a huge opportunity in small things.

  • How to solve JAVA menubar, layout and panel problem ?

    - by Berkay
    i'm not a java guy however i start implementing some security tools with java, in these days i'm creating a gui for my security tools : Here is the how my Gui looks: menuBar = new JMenuBar(); // construct menu bar // hash functions fileMenu = new JMenu("HASH FUNCTIONS"); // define file menu fileMenu.setMnemonic('H'); // shortcut hashes = new JMenuItem("Md5&Sha1"); // define file menu options hashes.setMnemonic('M'); hashes.addActionListener(this); fileMenu.add(hashes); menuBar.add(fileMenu); // add file menu to menu bar // symmetric encryption asMenu = new JMenu("SYMMETRIC ENCRYPTION"); // define format menu asMenu.setMnemonic('S'); // shortcut desItem = new JMenuItem("DES"); // define format menu options desItem.setMnemonic('D'); desItem.addActionListener(this); asMenu.add(desItem); ... ... menuBar.add(helpMenu); // add help menu to menu bar setJMenuBar(menuBar); // put menu bar on application textColor = Color.RED; when from the Menu desitem is selected, desvar is just for not showing the panel multiple times, it calls Panels () else if(e.getSource() == desItem && desvar ==1 ) { // make other panels unvisible. if(hashvar!=1) MyPanel.setVisible(false);//hash functions if(rsavar!=1) MyPanel3.setVisible(false);//rsa function if (dhvar!=1) MyPanel4.setVisible(false);//dh diffie hellman hashvar=1; rsavar=1; dhvar=1; ++desvar; desPanel=true; Panels(); } and in Panels() Method: if (hashPanel){ MyPanel.add("West",radioSHA1); MyPanel.add("West",radioMD5); MyPanel.add("Center", inputField); MyPanel.add("East",SubmitButton); MyPanel.add("South",resultHash); add(MyPanel); validate(); hashPanel=false; } i have many panels for example : -hash functions=mypanel1 , des=mypanel2, rsa functions= mypanel3 , dh= mypanel4 However in may other panals such as rsa function: i have to use some layout properties of the java:in this panel i selected to use gridbaglayout if (dhPanel){ System.out.println("rsa panel burda misin"); MyPanel3.add(pqLabel); MyPanel3.add(pLabel); MyPanel3.add(pTextArea); MyPanel3.add(qLabel); ... ... add(MyPanel3); generate_pqButton.addActionListener(this); calculate_nButton.addActionListener(this); ... ... GridBagLayout layout = new GridBagLayout(); GridBagConstraints gbc = new GridBagConstraints(); setLayout(layout); // x, y, w, h, wx, wy gbc.fill = GridBagConstraints.NONE; add (bit_length_label, gbc, 0, 0, 1, 1, 0, 10); add (p, gbc, 0, 1, 1, 1, 0, 10); add (g, gbc, 0, 2, 1, 1, 0, 10); add (a, gbc, 1, 3, 1, 1, 100, 10); add (x, gbc, 0, 4, 1, 1, 0, 10); add (gx, gbc, 0, 5, 1, 1, 0, 10); add (gxy, gbc, 0, 6, 1, 1, 0, 10); add (b, gbc, 1, 7, 1, 1, 100, 10); add (y, gbc, 0, 8, 1, 1, 0, 10); add (gy, gbc, 0, 9, 1, 1, 0, 10); add (gyx, gbc, 0, 10, 1, 1, 0, 10); add (sk, gbc, 1, 11, 1, 1, 100, 10); add (key, gbc, 0, 12, 1, 1, 0, 10); add (status, gbc, 1, 13, 1, 1, 100, 10); add (dhstart, gbc, 1, 14, 1, 1, 100, 10); add (bit_length_value, gbc, 1, 0, 1, 1, 100, 10); add (p_value, gbc, 1, 1, 1, 1, 100, 10); add (g_value, gbc, 1, 2, 1, 1, 100, 10); add (x_value, gbc, 1, 4, 1, 1, 100, 10); add (gx_value, gbc, 1, 5, 1, 1, 100, 10); add (gxy_value, gbc, 1, 6, 1, 1, 100, 10); add (y_value, gbc, 1, 8, 1, 1, 100, 10); add (gy_value, gbc, 1, 9, 1, 1, 100, 10); add (gyx_value, gbc, 1, 10, 1, 1, 100, 10); validate(); repaint(); rsaPanel=false; } Everthing seems okey however when i swith from one menu to another sometimes components are seen or apper in wrong places or mixed. where i'm doing wrong?

  • Problem receving in RXTX

    - by drhorrible
    I've been using RXTX for about a year now, without too many problems. I just started a new program to interact with a new piece of hardware, so I reused the connect() method I've used on my other projects, but I have a weird problem I've never seen before. The Problem The device works fine, because when I connect with hyperterminal, I send things and receive what I expect, and Serial Port Monitor(SPM) reflects this. However, when I run the simple hyperterminal-clone I wrote to diagnose the problem I'm having with my main app, bytes are sent, according to SPM, but nothing is received, and my SerialPortEventListener never fires. Even when I check for available data in the main loop, reader.ready() returns false. If I ignore this check, then I get an exception, details below. Relevant section of connect() method // Configure and open port port = (SerialPort) CommPortIdentifier.getPortIdentifier(name) .open(owner,1000) port.setSerialPortParams(baud, databits, stopbits, parity); port.setFlowControlMode(fc_mode); final BufferedReader br = new BufferedReader( new InputStreamReader( port.getInputStream(), "US-ASCII")); // Add listener to print received characters to screen port.addEventListener(new SerialPortEventListener(){ public void serialEvent(SerialPortEvent ev) { try { System.out.println("Received: "+br.readLine()); } catch (IOException e) { e.printStackTrace(); } } }); port.notifyOnDataAvailable(); Exception java.io.IOException: Underlying input stream returned zero bytes at sun.nio.cs.StreamDecoder.readBytes(StreamDecoder.java:268) at sun.nio.cs.StreamDecoder.implRead(StreamDecoder.java:306) at sun.nio.cs.StreamDecoder.read(StreamDecoder.java:158) at java.io.InputStreamReader.read(InputStreamReader.java:167) at java.io.BufferedReader.fill(BufferedReader.java:136) at java.io.BufferedReader.read(BufferedReader.java:157) at <my code> The big question (again) I think I've eliminated all possible hardware problems, so what could be wrong with my code, or the RXTX library? Edit: something interesting When I open hyperterminal after sending a bunch of commands from java that should have gotten responses, all of the responses appear immediately, as if they had been put in the buffer somewhere, but unavailable. Edit 2: Tried something new, same results I ran the code example found here, with the same results. No data came in, but when I switched to a new program, it came all at once. Edit 3 The hardware is fine, and even a different computer has the same problem. I am not using any sort of USB adapter. I've started using PortMon, too, and it's giving me some interesting results. Hyperterminal and RXTX are not using the same settings, and RXTX always polls the port, unlike HyperTerminal, but I still can't see what settings would affect this. As soon as I can isolate the configuration from the constant polling, I'll post my PortMon logs. Edit 4 Is it possible that some sort of Windows update in the last 3 months could have caused this? It has screwed up one of my MATLAB mex-based programs once. Edit 5 I've also noticed some things that are different between HyperTerminal, RXTX, and a separate program I found that communicates with the device (but doesn't do what I want, which is why I'm rolling my own program) HyperTerminal - set to no flow control, but Serial Port Monitor's RTS and DTR indicators are green Other program - not sure what settings it thinks it's using, but only SPM's RTS indicator is green RXTX - no matter what flow control I set, only SPM's CTS and DTR indicators are on. From Serial Port Monitor's help files (paraphrased): the indicators display the state of the serial control lines RTS - Request To Send CTS - Clear To Send DTR - Data Terminal Ready

  • What's wrong with this date behavior in C#?

    - by Jane McDowell
    If I output a formatted date as follows: DateTime.Parse("2010-06-02T15:26:37.789 +01:00").ToString("HH:mm:sszzz") I get the expected result: 15:26:37+01:00 However, if I parse the same date, convert to UTC and output with the same format as follows: DateTime.Parse("2010-06-02T15:26:37.789 +01:00").ToUniversalTime().ToString("HH:mm:sszzz") I get this: 14:26:37+01:00 Now those two dates, the local and UTC versions, should be exactly the same but the outputted text represents two different times. Why is this?

  • Exception: attempt to acquire a reference on a close SQLiteClosable

    I posted this back in May on the [android-developers] Google Group. I never heard back and was not able to reproduce the problem until one of my students did last week. I figured I'd post it here and see if it rang any bells for anyone. In one of my code samples, I have the following method: static Cursor getAll(SQLiteDatabase db, String orderBy) { return(db.rawQuery("SELECT * FROM restaurants "+orderBy, null)); } When I run it, sporadically, I get this: 05-01 14:45:05.849: ERROR/AndroidRuntime(1145): java.lang.IllegalStateException: attempt to acquire a reference on a close SQLiteClosable 05-01 14:45:05.849: ERROR/AndroidRuntime(1145): at android.database.sqlite.SQLiteClosable.acquireReference(SQLiteClosable.java:31) 05-01 14:45:05.849: ERROR/AndroidRuntime(1145): at android.database.sqlite.SQLiteProgram.<init>(SQLiteProgram.java:56) 05-01 14:45:05.849: ERROR/AndroidRuntime(1145): at android.database.sqlite.SQLiteQuery.<init>(SQLiteQuery.java:49) 05-01 14:45:05.849: ERROR/AndroidRuntime(1145): at android.database.sqlite.SQLiteDirectCursorDriver.query(SQLiteDirectCursorDriver.java:49) 05-01 14:45:05.849: ERROR/AndroidRuntime(1145): at android.database.sqlite.SQLiteDatabase.rawQueryWithFactory(SQLiteDatabase.java:1118) 05-01 14:45:05.849: ERROR/AndroidRuntime(1145): at android.database.sqlite.SQLiteDatabase.rawQuery(SQLiteDatabase.java:1092) 05-01 14:45:05.849: ERROR/AndroidRuntime(1145): at apt.tutorial.Restaurant.getAll(Restaurant.java:14) This makes no sense to me. The database is definitely open. The SQLiteClosable is the SQLiteQuery created by SQLiteQueryDriver, and I see no evidence that there is an object pool or something going on here that might explain how a "new" SQLiteClosable is already closed. The fact that it is sporadic (meaning the same UI operations sometimes trigger the exception, but not always) suggests some sort of pool, race condition, or something...but I'm not sure where. Thoughts? Thanks! UPDATE: The code in question is from the LunchList tutorials out of my Android Programming Tutorials book. It's a bit spread out and not terribly suitable for posting directly in SO. You can download the code for that book from the above link if you want to take a look at it. I do not recall exactly which edition of the tutorial the student was working on at the time, though it was in the Tutorial 12-Tutorial 16 range. I was mostly hoping to run across somebody who had tripped over this problem before and had a likely culprit. I'm fairly certain my database is open. Thanks again!

  • How to make a character jump, both on objects and just normal jump.

    - by haxerflaxer
    Hi, I'm kind of a beginner when it comes to java programming, and I have a project in school where I'm going to create a game much like Icy Tower. And my question is, how am I going to write to make the character stand on the ground and be able to jump up on objects? Here's my code so far: Part one package Sprites; import java.awt.Image; import java.awt.event.KeyEvent; import javax.swing.ImageIcon; public class jumper { private String jump = "oka.png"; private int dx; private int dy; private int x; private int y; private Image image; public jumper() { ImageIcon ii = new ImageIcon(this.getClass().getResource(jump)); image = ii.getImage(); x = 50; y = 100; } public void move() { x += dx; y += dy; } public int getX() { return x; } public int getY() { return y; } public Image getImage() { return image; } public void keyPressed(KeyEvent e) { int key = e.getKeyCode(); if (key == KeyEvent.VK_LEFT) { dx = -5; ImageIcon ii = new ImageIcon(this.getClass().getResource("oki.png")); image = ii.getImage(); } if (key == KeyEvent.VK_RIGHT){ dx = 5; ImageIcon ii = new ImageIcon(this.getClass().getResource("oka.png")); image = ii.getImage(); } if (key == KeyEvent.VK_SPACE) { dy = -5; } if (key == KeyEvent.VK_DOWN) { dy = 5; } } public void keyReleased(KeyEvent e) { int key = e.getKeyCode(); if (key == KeyEvent.VK_LEFT) { dx = 0; } if (key == KeyEvent.VK_RIGHT){ dx = 0; } if (key == KeyEvent.VK_SPACE) { dy = 0; } if (key == KeyEvent.VK_DOWN) { dy = 0; } } } Part two package Sprites; import java.awt.Color; import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.Toolkit; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.event.KeyAdapter; import java.awt.event.KeyEvent; import javax.swing.JPanel; import javax.swing.Timer; public class board extends JPanel implements ActionListener { private Timer klocka; private jumper jumper; public board() { addKeyListener(new TAdapter()); setFocusable(true); setBackground(Color.WHITE); setDoubleBuffered(true); jumper = new jumper(); klocka = new Timer(5, this); klocka.start(); } public void paint(Graphics g) { super.paint(g); Graphics2D g2d = (Graphics2D)g; g2d.drawImage(jumper.getImage(), jumper.getX(), jumper.getY(), this); Toolkit.getDefaultToolkit().sync(); g.dispose(); } public void actionPerformed(ActionEvent e) { jumper.move(); repaint(); } private class TAdapter extends KeyAdapter { public void keyReleased(KeyEvent e) { jumper.keyReleased(e); } public void keyPressed(KeyEvent e) { jumper.keyPressed(e); } } } Part three package Sprites; import javax.swing.JFrame; public class RType extends JFrame { public RType() { add(new board()); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setSize(800, 600); setLocationRelativeTo(null); setTitle("R - type"); setResizable(false); setVisible(true); } public static void main(String[] args) { new RType(); } } I really appreciate all the help I can get!

  • mint linux, DVD drive keeps randomly being accessed. unsure how to find culprit

    - by juicebox
    I have a workstation with mint linux 12. It seems like the DVD drive on the machine keeps randomly "activating". By activating it makes noise, the light turns on, and it seems like it is checking if a disk is in it. At first I thought I was being hacked and someone/something was trying to check if I had media in the DVDRom drive. I ruled that out with netstat and rkhunter. I checked my logs and the only thing I can find that might help point out the problem are these repeated chunks in syslog: Mar 24 17:47:31 rich-MINT kernel: [ 9846.551422] ata2.00: cmd a0/00:00:00:08:00/00:00:00:00:00/a0 tag 0 pio 16392 in Mar 24 17:47:31 rich-MINT kernel: [ 9846.551424] res 51/40:01:00:00:00/00:00:00:00:00/a0 Emask 0x10 (ATA bus error) Mar 24 17:47:31 rich-MINT kernel: [ 9846.551427] ata2.00: status: { DRDY ERR } Mar 24 17:47:31 rich-MINT kernel: [ 9846.551433] ata2.00: hard resetting link Mar 24 17:47:32 rich-MINT kernel: [ 9846.868012] ata2.01: hard resetting link Mar 24 17:47:32 rich-MINT kernel: [ 9847.344054] ata2.00: SATA link up 1.5 Gbps (SStatus 113 SControl 310) Mar 24 17:47:32 rich-MINT kernel: [ 9847.344067] ata2.01: SATA link up 3.0 Gbps (SStatus 123 SControl 300) Mar 24 17:47:32 rich-MINT kernel: [ 9847.376118] ata2.00: configured for PIO0 Mar 24 17:47:32 rich-MINT kernel: [ 9847.393047] ata2.01: configured for UDMA/133 Mar 24 17:47:32 rich-MINT kernel: [ 9847.397046] ata2: EH complete and again Mar 24 17:55:28 rich-MINT kernel: [10323.633268] sr 1:0:0:0: ioctl_internal_command return code = 8000002 Mar 24 17:55:28 rich-MINT kernel: [10323.633270] : Sense Key : Aborted Command [current] [descriptor] Mar 24 17:55:28 rich-MINT kernel: [10323.633275] : Add.

  • unable to access a NAT'ed IP via a VPN on Windows 7

    - by crmpicco
    I connect to a range of servers hosted by one provider via a VPN. I can connect to the VPN fine, however when I then go and try and connect to the server(s) it fails. A NAT'ed IP address that has worked up until today, has stopped working either via SSH/SFTP. As you can see below, if I try and ping the IP then it responds with Destination host unreachable, but, for some reason it says the reply is from 192.168.0.8? If it enter this IP address in my browser, I get nothing. Where is this IP coming from and is there any good reason why I cannot access the IP I am trying to ping?

  • Frequent and weird wifi disconnections

    - by Sidou
    How would you explain, troubleshoot (and solve) the following problem? Wifi ADSL modem router D-link 2640R installed in living room at about 1.8m height. Working fine, synchronising and getting/serving stable internet connection. First situation: -Laptop 01 in other end of the house, let's say in room01 southern to the living room, distant by about 15m. Getting stable signal of good to very good quality. No disconnection. -Laptop 02 in room02 opposite to room01 (5m West) which makes it almost at the same distance and direction from the router located 15m North. Getting stable signal of good to very good quality. No disconnection. Second situation: -Laptop 01 moved to room03 Northern to the living room (actually just 3m behind the wall where the router lies). Getting stable signal of excellent quality. No disconnection. -Laptop 02 still in room02 but now experiences frequent disconnections (actually almost impossible to get the Internet even though the signal level is still very good. Either no Internet with the wifi icon appearing connected to access point or no connection established at all which happens every 2 minutes and that means virtually no Internet at all as I can just get a timeframe of 1 minute or so to load any website or even get to the router's web based control panel. If Laptop 01 is completely shut down or its wifi adapters shut down or even still working but its wifi MAC address forbidden, then Laptop 02 has no problem at all. If Laptop 02 is moved to a nearer location to the router, in the living room for instance, then no connection problem occurs even if Laptop 01 is also connected. And also if we move back Laptop 01 to its original location (room 01), then no problem as well. I'm completely lost and don't know how to address this issue. I tried to change the Wifi channel and even tried the auto channel scan but that didn't solve it. I know that the problem is probably coming from Laptop 01 being in its new location or some sort of interference as the problem occurs only under the described condition but I have no idea how to solve it! I also scanned the neighborhood for wifi jam using InSSIDer, there are few other access points but they don't seem to affect the situation. Any ideas about the steps to follow or tools to use ?
