  • Detect car acceleration in Android app?

    - by Stud33
    I want to incorporate some Accelerometer code into a Android application im working and want to see if this is possible. Basically what I need is for the code to detect car acceleration motion. I am not wanting to determine speed with the code but just distinguish if the phone is in a car and has accelerated motion (Hence the car is moving for the first time). I have gone through many different accelerometer applications to see if this motion produces a viable profile to go off of and it appears it does. Just looking for something that popups a "Hello World" dialog when it detects your in the car and its moving for the first time down the street. Any help would be appreciated and a simple yes or no its possible would work. I would also be interested in compensating anyone that is capable of doing this as well. I need this done like yesterday so please let me know. Thank You, JTW

  • JPA and MySQL transaction isolation level

    - by armandino
    I have a native query that does a batch insert into a MySQL database: String sql = "insert into t1 (a, b) select x, y from t2 where x = 'foo'"; EntityTransaction tx = entityManager.getTransaction(); try { tx.begin(); int rowCount = entityManager.createNativeQuery(sql).executeUpdate(); tx.commit(); return rowCount; } catch(Exception ex) { tx.rollback(); log.error(...); } This query causes a deadlock: while it reads from t2 with insert .. select, another process tries to insert a row into t2. I don't care about the consistency of reads from t2 when doing an insert .. select and want to set the transaction isolation level to READ_UNCOMMITTED. How do I go about setting it in JPA?

  • Eclipse RCP: Making use of configuration directory

    - by Dot
    Hello, My Eclipse RCP application requires a configuration file that contains some information to connect to a remote database. Where is the best location to store this configuration file? Can I use the default configuration directory (where 'config.ini' is usually stored) for this purpose? If so, how can I get a File instance to this location programmatically? I also note that this directory does not exist in my Eclipse IDE. Thanks.

  • How to modularize a b2b webservice transformation application

    - by hstoerr
    How would you modularize a large application that has some incoming (SOAP) webservices, some outgoing webservices, transformations between them and internal formats, internal logging services, accesses external archiving webservices, delays stuff and works on this asynchronously and so forth? One way is to split the functionality into a collection of WAR, deploy all of them on one application server and have them communicate with internal webservices. This has some overhead, especially if the messages are large, and you might run into performance problems due to thread count restrictions and so forth. Another way would be to put everything into a giant WAR, such that you can communicate directly. Not exactly modularization. What would you do?

  • Standard Place for an Empty String Array in the JDK

    - by Simon B
    Hi is there a standard place for accessing empty array constants in the JDK 1.5. When I want to do a conversion from a String Collection (e.g. ArrayList)to a String Array I find myself using my own which is defined in my own Constants class: public static final String[] EMPTY_STRING_ARRAY = new String[0]; And then in my client code something like: String[] retVal = myStringList.toArray(Constants.EMPTY_STRING_ARRAY); return retVal; I was wondering if this is the "idiomatic" of doing it or if I'm missing something I get the impression from the brief search I did that this kind of thing is prevalent in many people's code. Any ideas, answers, comment (aside from that I shouldn't really use String Arrays) greatly appreciated, Cheers Simon

  • Setting fonts in a JTextArea

    - by vuj
    I've got a JTextArea which has the following text "Text1 Text2 Text3". Is there a way I can make all of them different fonts? E.g. "Text1" is bold, "Text2" is italic and "Text3" is normal? I know I can create a Font object, however I can only apply it the JTextArea object. Thanks.

  • Restlet/Jackson works differently when object implements Serializable

    - by ravyoli
    I am sending an object with some primitive fields using Restlet with Jackson converter. Up until now it worked great. But then I needed my object to implement Serializable, because I need to store it in memcache of GAE. For some reason - when the class implements Serializable, things stop working. Restlet sends a different string representation from before, and I can't even print that string in the server. I tried printing its byte value, char-by-char and the first numbers are: 0xfffd 0xfffd 0x0000 0x0005 0x0073 0x0072 Thanks a lot!

  • disable scrolling to cell in focus

    - by Victor
    I have a jtable inside of a scrollpane. how can i stop the scrollpane from scrolling up or down when a cell that is partly out of view gains focus? the problem is i am setting the cells to editable when the user mouses over them, so when you mouse over a cell that's partly out of view, the view changes suddenly. I don't like this behaviour. any ideas on how to change it?

  • Difference in output from use of synchronized keyword and join()

    - by user2964080
    I have 2 classes, public class Account { private int balance = 50; public int getBalance() { return balance; } public void withdraw(int amt){ this.balance -= amt; } } and public class DangerousAccount implements Runnable{ private Account acct = new Account(); public static void main(String[] args) throws InterruptedException{ DangerousAccount target = new DangerousAccount(); Thread t1 = new Thread(target); Thread t2 = new Thread(target); t1.setName("Ravi"); t2.setName("Prakash"); t1.start(); /* #1 t1.join(); */ t2.start(); } public void run(){ for(int i=0; i<5; i++){ makeWithdrawl(10); if(acct.getBalance() < 0) System.out.println("Account Overdrawn"); } } public void makeWithdrawl(int amt){ if(acct.getBalance() >= amt){ System.out.println(Thread.currentThread().getName() + " is going to withdraw"); try{ Thread.sleep(500); }catch(InterruptedException e){ e.printStackTrace(); } acct.withdraw(amt); System.out.println(Thread.currentThread().getName() + " has finished the withdrawl"); }else{ System.out.println("Not Enough Money For " + Thread.currentThread().getName() + " to withdraw"); } } } I tried adding synchronized keyword in makeWithdrawl method public synchronized void makeWithdrawl(int amt){ and I keep getting this output as many times I try Ravi is going to withdraw Ravi has finished the withdrawl Ravi is going to withdraw Ravi has finished the withdrawl Ravi is going to withdraw Ravi has finished the withdrawl Ravi is going to withdraw Ravi has finished the withdrawl Ravi is going to withdraw Ravi has finished the withdrawl Not Enough Money For Prakash to withdraw Not Enough Money For Prakash to withdraw Not Enough Money For Prakash to withdraw Not Enough Money For Prakash to withdraw Not Enough Money For Prakash to withdraw This shows that only Thread t1 is working... If I un-comment the the line saying t1.join(); I get the same output. So how does synchronized differ from join() ? If I don't use synchronize keyword or join() I get various outputs like Ravi is going to withdraw Prakash is going to withdraw Prakash has finished the withdrawl Ravi has finished the withdrawl Prakash is going to withdraw Ravi is going to withdraw Prakash has finished the withdrawl Ravi has finished the withdrawl Prakash is going to withdraw Ravi is going to withdraw Prakash has finished the withdrawl Ravi has finished the withdrawl Account Overdrawn Account Overdrawn Not Enough Money For Ravi to withdraw Account Overdrawn Not Enough Money For Prakash to withdraw Account Overdrawn Not Enough Money For Ravi to withdraw Account Overdrawn Not Enough Money For Prakash to withdraw Account Overdrawn So how does the output from synchronized differ from join() ?

  • Invert linear linked list

    - by ArtWorkAD
    Hi, a linear linked list is a set of nodes. This is how a node is defined (to keep it easy we do not distinguish between node an list): class Node{ Object data; Node link; public Node(Object pData, Node pLink){ this.data = pData; this.link = pLink; } public String toString(){ if(this.link != null){ return this.data.toString() + this.link.toString(); }else{ return this.data.toString() ; } } public void inc(){ this.data = new Integer((Integer)this.data + 1); } public void lappend(Node list){ Node child = this.link; while(child != null){ child = child.link; } child.link = list; } public Node copy(){ if(this.link != null){ return new Node(new Integer((Integer)this.data), this.link.copy()); }else{ return new Node(new Integer((Integer)this.data), null); } } public Node invert(){ Node child = this.link; while(child != null){ child = child.link; } child.link = this;.... } } I am able to make a deep copy of the list. Now I want to invert the list so that the first node is the last and the last the first. The inverted list has to be a deep copy. I started developing the invert function but I am not sure. Any Ideas? Update: Maybe there is a recursive way since the linear linked list is a recursive data structure. I would take the first element, iterate through the list until I get to a node that has no child and append the first element, I would repeat this for the second, third....

  • Python code translation to JVM

    - by jldupont
    Is there such a thing as a "translator" (for lack of a better word in my mind now) that translates Python code directly to JVM / Dalvik bytecode? Would be great for writing Android applications in Python! NOTE: I know about the scripting capabilities of the Android platform but I am looking for something that would generate a '.apk' without having to install the 'scripting' package... annoying for end-users.

  • Swing - how to mix JTextField and JTextAreas and have same visual appearance?

    - by I82Much
    I am using miglayout to create a form in which there are JTextFields (short input answers) as well as JTextAreas (Longer answers). The problem is twofold. The border placed around a Scrollpane wrapped text area does not match that of a Text Field. The width and placement of the textarea/textfield differ, causing them not to line up correctly. Source code: package test2; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.JScrollPane; import javax.swing.JTextArea; import javax.swing.JTextField; import net.miginfocom.swing.MigLayout; public class Test extends JPanel { private static final int NUM_CHARACTERS_WIDTH = 20; private static final int NUM_ROWS = 5; public Test() { setLayout(new MigLayout( "wrap 2", // Align text labels on the so their right edge meets left edge of the text fields "[right][left]" )); add(new JLabel("Text field:")); add(new JTextField(NUM_CHARACTERS_WIDTH)); add(new JLabel("No scrollpane text area:")); add(new JTextArea(NUM_ROWS, NUM_CHARACTERS_WIDTH)); add(new JLabel("Scrollpane text area:")); add(new JScrollPane(new JTextArea(NUM_ROWS, NUM_CHARACTERS_WIDTH))); add(new JLabel("Text field:")); add(new JTextField(NUM_CHARACTERS_WIDTH)); } public static void main(String[] args) { JFrame frame = new JFrame(""); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel panel = new Test(); frame.add(panel); frame.pack(); frame.setVisible(true); } } What's the preferred way to mix and match jtextfield and jtextareas, while still maintaining visual harmony? I notice now that the text field has a blue highlight around it when focus is in it, as opposed to the text area... another source of visual discontinuity.

  • Accessing Spring beans from a Tiles view (JSP)

    - by Sinuhe
    In Spring MVC I can access my beans in JSP using JstlView's exposedContextBeanNames (or exposeContextBeansAsAttributes). For example, then, in my JSP I can write (${properties.myProperty). But when the same JSP is a part of a tiles view, these properties aren't accessible. Is possible to configure Tiles properly or access these properties in another way? I'm using Spring MVC 3.0.2 and Tiles 2.2.1. Here's a bit of my configuration: <bean id="tilesViewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver"> <property name="order" value="1"/> <property name="viewClass" value="org.springframework.web.servlet.view.tiles2.TilesView" /> </bean> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/> <property name="order" value="2"/> <property name="prefix" value="/WEB-INF/views/"/> <property name="suffix" value=".jsp"/> <property name="exposedContextBeanNames"> <list><value>properties</value></list> </property> </bean>

  • Background settings for a JDesktopPane

    - by EricR
    I'm using a self-made DesktopPaneUI for a JDesktopPane, I've written the proper methods for the class, and I'm running into trouble. When I resize the JDesktopPane, the background image doesn't resize with the frame. The image appears to be clipped at the size it was when the window initially opened. I'm giving it an image larger than the window, and I'm still having this problem. Here's my method call inside the constructor of my desktopUI class. super(); this.background = javax.imageio.ImageIO.read(new File(fileName)); Is there a way I can change my main class where I set the UI, or the myDesktopPaneUI class such that the background still fills the window when the JDesktopPane changes size? setUI(new myDesktopPaneUI("media/bg.jpg"));
