  • AdMob Android integration - what permissions to ask for?

    - by AngryHacker
    In the various videos on the AdMob integration, I've seen that only permission to access the internet is asked for: <uses-permission android:name="android.permission.INTERNET" /> Not that I am an expert in advertising, but wouldn't AdMob need the user's geographic location as well, so that they can serve location specific ads? Or avoid serving certain ads based on a location, like maybe not offering me a Big Mac if I am in India or not adverting a ham sandwich if I am in an Arab country? If AdMob needs those permissions, how do I ask for them?

  • How to click through JGlassPane With MouseListener to UI behind it

    - by Epicmaster
    I have a JFrame and a bunch of JComponents on top of the JFrame. I need to make use of the JGlassPane and I used this implementation to set it up. JPanel glass = new JPanel(); frame.setGlassPane(glass); glass.setVisible(true); glass.setOpaque(false); After doing so I can't select any JButtons or other JComponents under the JGlassPane. Is there a way to have only the components on the GlassPane selectable while still having the ability to select components under the GlassPane? Edit I forgot to mention (not knowing this would be relevant) that I did attach both a MouseListener and a MouseMotionListener to the glass pane. Is there a way to pass the Mouse Events to other components and only use them when needed?

  • JUnit Rule TemporaryFolder

    - by Jeff Storey
    I'm creating a TemporaryFolder using the @Rule annotation in JUnit 4.7. I've tried to create a new folder that is a child of the temp folder using tempFolder.newFolder("someFolder") in the @Before (setup) method of my test. It seems as though the temporary folder gets initialized after the setup method runs, meaning I can't use the temporary folder in the setup method. Is this correct (and predictable) behavior? thanks, Jeff

  • How do I correctly decode unicode parameters passed to a servlet

    - by Grant Wagner
    Suppose I have: <a href="http://www.yahoo.com/" target="_yahoo" title="Yahoo!&#8482;" onclick="return gateway(this);">Yahoo!</a> <script type="text/javascript"> function gateway(lnk) { window.open(SERVLET + '?external_link=' + encodeURIComponent(lnk.href) + '&external_target=' + encodeURIComponent(lnk.target) + '&external_title=' + encodeURIComponent(lnk.title)); return false; } </script> I have confirmed external_title gets encoded as Yahoo!%E2%84%A2 and passed to SERVLET. If in SERVLET I do: Writer writer = response.getWriter(); writer.write(request.getParameter("external_title")); I get Yahoo!â„¢ in the browser. If I manually switch the browser character encoding to UTF-8, it changes to Yahoo!TM (which is what I want). So I figured the encoding I was sending to the browser was wrong (it was Content-type: text/html; charset=ISO-8859-1). I changed SERVLET to: response.setContentType("text/html; charset=utf-8"); Writer writer = response.getWriter(); writer.write(request.getParameter("external_title")); Now the browser character encoding is UTF-8, but it outputs Yahoo!â?¢ and I can't get the browser to render the correct character at all. My question is: is there some combination of Content-type and/or new String(request.getParameter("external_title").getBytes(), "UTF-8"); and/or something else that will result in Yahoo!TM appearing in the SERVLET output?

  • ClassLoader exceptions being memoized

    - by Jim
    Hello, I am writing a classloader for a long-running server instance. If a user has not yet uploaded a class definition, I through a ClassNotFoundException; seems reasonable. The problem is this: There are three classes (C1, C2, and C3). C1 depends on C2, C2 depends on C3. C1 and C2 are resolvable, C3 isn't (yet). C1 is loaded. C1 subsequently performs an action that requires C2, so C2 is loaded. C2 subsequently performs an action that requires C3, so the classloader attempts to load C3, but can't resolve it, and an exception is thrown. Now C3 is added to the classpath, and the process is restarted (starting from the originally-loaded C1). The issue is, C2 seems to remember that C3 couldn't be loaded, and doesn't bother asking the classloader to find the class... it just re-throws the memoized exception. Clearly I can't reload C1 or C2 because other classes may have linked to them (as C1 has already linked to C2). I tried throwing different types of errors, hoping the class might not memoize them. Unfortunately, no such luck. Is there a way to prevent the loaded class from binding to the exception? That is, I want the classloader to be allowed to keep trying if it didn't succeed the first time. Thanks!

  • Good programming style when handling multiple objects

    - by Glitch
    I've been programming a software version of a board game. Thus far I have written the classes which will correspond to physical objects on the game board. I'm well into writing the program logic, however I've found that many of the logic classes require access to the same objects. At first I was passing the appropriate objects to methods as they were called, but this was getting very tedious, particularly when the methods required many objects to perform their tasks. To solve this, I created a class which initialises and stores all the objects I need. This allows me to access an object from any class by calling Assets.dice(), for example. But now that I've thought about it, this doesn't seem right. This is why I'm here, I fear that I've created some sort of god class. Is this fear unfounded, or have I created a recipe for disaster?

  • Grails Deployment - Fastest way to get deployed?

    - by gav
    Hi All, If anyone has or is running a Grails application on their server I would appreciate some details on where to go after creating the WAR. Background I chose grails because with Google App Engine and the App Engine Plugin deployment should have been trivial. This issue is that there is a bug which makes any application pretty much unusable, I wish this had been more prominent so I didn't have to get to the point of seeing the error myself before I was aware of it. The next option was EC2 and the Cloud Tools plugin, it seems Cloud Tools worked with grails 1.0 but doesn't work with the current 1.2.1 due to issues getting the JAR dependencies. It also seems that Cloud Tools has been succeeded by Cloud Foundry which is in beta, will cost extra money and has limited places (I signed up but haven't got an e-mail). Question My application is painfully trivial, it has a small load, small data requirements and doesn't need to scale past 5 users. How can I deploy my grails app as quickly and painlessly as possible? Specifically: Are there any hosting companies that have tomcat installed on their servers out of the box that I can sign up to and use that will just work? Do you know of any simple tutorials for getting a grails application deployed to EC2 without Cloud Tools? Thanks in advance, Gav Side-note: I picked grails because of good advice from SO, it should have been a very short time from development to deployed product except the tools for auto-deployment aren't that mature and I've never configured a server before.

  • jsp get ip address

    - by Alan
    Hello, whats the best way of preventing someone from voting twice? How do i get the users ip address? What if they are on a large network? will everyone on that network show the same ip? thanks UPDATE: request.getRemoteAddr() and request.getRemoteHost() return the Server names, not the client's host name and ip. Anyone else got any bright ideas? Ok, so lets forget about the voting twice thing. Im just trying to get the users ip address? i tried request.getRemoteAddr() and request.getRemoteHost() and think im getting the servers address. I have access to two separate networks and am getting the same IP address :(

  • Using Google Common Collection in GWT

    - by Jeeyoung Kim
    This is a simple problem, but I'm having problems with it... I'm trying to use Google common collection's Objects.equal() method in a GWT client code, but I'm keep getting the error "20:12:10.001 [ERROR] [gwt_regex] Line 39: No source code is available for type com.google.common.base.Objects; did you forget to inherit a required module?" Tried to Google for the answer, but couldn't find any answer regarding this - everyone just said "Google collection should work off the box with GWT".

  • Pause and resume thread drawing to SurfaceView

    - by fhucho
    I am developing a chess game for Android (http://androidchess.appspot.com), using SurfaceView for the chessboard. I have a drawing Thread, that draws the chessboard in a loop. The problem is that when there are no active animations (this is more that 90% of time), it makes no sense to waste CPU and battery for drawing. How should I solve this? Maybe somehow pausing and resuming the drawing Thread?

  • Why is the EntityManager in my GAE + Spring (+graniteds) project reset to null?

    - by prefabSOFT
    Hi all, I'm having a problem with autowiring my EntityManager. Actually at server startup I can see that the injection works ok, though when trying to use my EntityManager it appears to be null again. @Component public class DataDaoImpl { protected EntityManager entityManager; @Autowired public void setEntityManager(EntityManager entityManager) { System.out.println("Injecting "+entityManager); //works! this.entityManager = entityManager; } public void createData(String key, String value) { System.out.println("In createData entityManager is "+entityManager); //entityManager null!? ... Output: Injecting org.datanucleus.store.appengine.jpa.DatastoreEntityManager@a60d19 The server is running at http://localhost:8888/ In createData entityManager is null So somehow the autowired entityManager is reset to null when trying to use it. It's a graniteds powered project though I don't think this is graniteds related. Any ideas? Thanks a lot in advance, Jochen

  • String Manipulation: Splitting Delimitted Data

    - by Milli Szabo
    I need to split some info from a asterisk delimitted data. Data Format: NAME*ADRESS LINE1*ADDRESS LINE2 Rules: 1. Name should be always present 2. Address Line 1 and 2 might not be 3. There should be always three asterisks. Samples: MR JONES A ORTEGA*ADDRESS 1*ADDRESS2* Name: MR JONES A ORTEGA Address Line1: ADDRESS 1 Address Line2: ADDRESS 2 A PAUL*ADDR1** Name: A PAUL Address Line1: ADDR1 Address Line2: Not Given My algo is: 1. Iterate through the characters in the line 2. Store all chars in a temp variables until first * is found. Reject the data if no char is found before first occurence of asterisk. If some chars found, use it as the name. 3. Same as step 2 for finding address line 1 and 2 except that this won't reject the data if no char is found My algo looks ugly. The code looks uglier. Spliting using //* doesn't work either since name can be replaced with address line 1 if the data was *Address 1*Address2. Any suggestion?

  • Break a while loop without using If or Break

    - by Justin
    I need to create a program that uses while to find the volume of a cylinder. I need the while loop to break if the user inputs a negative value for the height. My code looks like this: double sentinel=1, h=1, v=0, r, count=0; // declares all variables needed final double PI=3.14159; boolean NotNegative=true; while(NotNegative){// && count==0){ // while both the height is positive AND the total times run is 0 System.out.print("Enter height (Use negative to exit): "); // has the user input the height h=Double.parseDouble(br.readLine()); sentinel=h; // save sentinel as the inputted height while(sentinel>0){ System.out.print("Enter radius: "); // have the user input the radius r=Double.parseDouble(br.readLine()); v=PI*(r*r)*h; // find the volume System.out.println("The volume is " + v); // print out the volume count++; // increase the count each time this runs NotNegative=true; sentinel=-1; } } Any help?

  • Spring MVC- several parts/views from a controller

    - by leeeroy
    i'm looking into using Spring MVC - how would I structure the fact that a page can be composed of several different views Consider a controller that's basically: public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { List<Post> posts = repository.getNewPosts(); return new ModelAndView("posts", "posts", posts); } However, I decide that on every page, I'd also want a side "pane" that shows data based on some logic. That "pane" would just be a .jsp that gets included from the above "posts" view, and I could change my controller to: public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { List<Post> posts = repository.getNewPosts(); List<Items> items= repository.getItems(); return new ModelAndView("model", "model", new MyCommonViewModel(posts,items)); } But then I'd have to change every controller to also do List<Items> items= repository.getItems(); , and change everything again the next time I come up with something new. This seems messy. How do I structure this ? `

    I used myPanel.setLayout(new BoxLayout(myPanel, BoxLayout.Y_AXIS)); to order panels vertically (one under another one). But myPanel defined in the shown way change the included panel. In more details, it tries to set the same hight and width for the included panels. Can it be changed? Can BoxLayout adopt size of the included elements?

  • How can I stop my application?

    - by Roman
    I have the main thread from which I start a window using invokeLater. I run my application from command line. So, when application is running I see the window and my command line is "blocked" by the application. I can stop the application either by closing the window (as a result the command line is unblocked) or by typing Ctrl-C in the command line (as a result the window disappear). I wanted to be able to stop the application by clicking on a button in the window of the application. I used setVisible(false) for that. But in this way I can achieve the goal only partially. My window really disappear but the command line is still blocked. So, the software is still running. Well, I assume it's because some other threads are still running. But how can I easily close all these threads (like I do by closing the window of the application manually).
