  • PNG Textures not loading on HTC desire

    - by Matthew Tatum
    Hi I'm developing a game for android using OpenGL es and have hit a problem: My game loads fine in the emulator (windows xp and vista from eclipse), it also loads fine on a T-Mobile G2 (HTC Hero) however when I load it on my new HTC Desire none of the textures appear to load correctly (or at all). I'm suspecting the BitmapFactory.decode method although I have no evidence that that is the problem. All of my textures are power of 2 and JPG textures seem to load (although they don't look great quality) but anything that is GIF or PNG just doesn't load at all except for a 2x2 red square which loads fine and one texture that maps to a 3d object but seems to fill each triangle of the mesh with the nearest colour). This is my code for loading images: AssetManager am = androidContext.getAssets(); BufferedInputStream is = null; try { is = new BufferedInputStream(am.open(fileName)); Bitmap bitmap; bitmap = BitmapFactory.decodeStream(is); GLUtils.texImage2D(GL10.GL_TEXTURE_2D, 0, bitmap, 0); bitmap.recycle(); } catch(IOException e) { Logger.global.log(Level.SEVERE, e.getLocalizedMessage()); } finally { try { is.close(); } catch(Exception e) { // Ignore. } } thanks

  • Configure multiple keystores in JBoss depending on requested hostname

    - by Mo
    Hello, I have my J2EE application deployed into a JBossAS. My Application has to respond to two different hostnames (https://foo.com/myApp and https://bar.com/myApp). It is the same instance of the app serving those two hostnames. But I don't know how to configure the keystores. I need different keystores for each hostname. Is there a way to tie a virtual host in JBoss' server.xml to a specific connector? Or do I have to use two different IP-addresses and create a connector for each? A solution that does not require a second IP-address would be greatly appreciated.

  • Tomcat memory issue

    - by user305210
    Hello, I have noticed that my application that is running on Tomcat 5 starts with 1gig of memory and as soon as it starts receiving requests from client, the memory starts dropping until it is down to 100MBs and troubles start from there. I am looking at /manager/status page of tomcat under JVM section where "Free Memory", "Total Memory", "Max Memory" is listed. Is this an indicator of memory leak? Memory does not seem to be freed-up automatically even if there are no requests coming from client machines.

  • JDOQL Any way to avoid multiple .contains() calls in the query when searching for the presence of on

    - by Finbarr
    The question pretty much says it all. If I have a class Class A public class A { ... private List<String> keys; ... } And I want to select all A instances from the DataStore that have atleast one of a List of keys, is there a better way of doing it than this: query = pm.newQuery(A.class); query.setFilter("keys.contains(:key1) || keys.contains(:key2) || keys.contains(:key3)"); List<A> results = (List<A>)query.execute(key1, key2, key3); This has not yet been implemented, so I am open to radical suggestions.

  • Testing a quadratic equation

    - by user1201587
    I'm doing a code testing for a program that calculate the results for a quadratic equation I need to have test data for the following situation, when a is not zero and d positive there is two possibilities which are in the code below, I need to find an example for the first satiation when Math.abs(b / a - 200.0) < 1.0e-4 , all the values that I have tried, excute the second one caption= "Two roots"; if (Math.abs(b / a - 200.0) < 1.0e-4) { System.out.println("first one"); x1 = (-100.0 * (1.0 + Math.sqrt(1.0 - 1.0 / (10000.0 * a)))); x2 = (-100.0 * (1.0 - Math.sqrt(1.0 - 1.0 / (10000.0 * a)))); } else { System.out.println("secrst one"); x1 = (-b - Math.sqrt(d)) / (2.0 * a); x2 = (-b + Math.sqrt(d)) / (2.0 * a); } } }

  • Split string into sentences based on periods

    - by rookie
    Hi all, I have written this piece of code that splits a string and stores it in a string array:- String[] sSentence = sResult.split("[a-z]\.\s+"); However, I've added the [a-z] because I wanted to deal with some of the abbreviation problem. But then my result shows up as so:- Furthermore when Everett tried to instruct them in basic mathematics they proved unresponsiv I see that I loose the pattern specified in the split function. Its okay for me to loose the period, but loosing the last letter of the word disturbs its meaning. Could some one help me with this and in addition also could someone help me with dealing with abbreviations? Like because I split the string based on periods, I do not want to loose the abbreviations. Thanks in advance

  • Is there a file diff tool that allows for exceptions?

    - by Kevin
    We currently use Beyond Compare 3.0 and I am quite pleased with it. However, it would be great if I could easily specify an exclusion for a specific one-time case. This is needed when I am doing a code review of some refactoring. For instance: Old code doSomething(ConstantsInterface.FOOBAR); New code: doSomething(BetterEnumeration.FOOBAR); In this case, I have hundreds of changes that I am reviewing that are essentially all the same exact change and I just want to see the exceptions. It would be great if I could easily specify an exception that indicates these two cases are equal. I know of a way to do it in the grammar, but it is tedious and cumbersome in the case where there are ten or so exceptions. Any other tips?

  • Hibernate Many-To-One Foreign Key Default 0

    - by user573648
    I have a table where the the parent object has an optional many-to-one relationship. The problem is that the table is setup to default the fkey column to 0. When selecting, using fetch="join", etc-- the default of 0 on the fkey is being used to try over and over to select from another table for the ID 0. Of course this doesn't exist, but how can I tell Hibernate to treat a value of 0 to be the same as NULL-- to not cycle through 20+ times in fetching a relationship which doesn't exist? <many-to-one name="device" lazy="false" class="Device" not-null="true" access="field" cascade="none" not-found="ignore"> <column name="DEVICEID" default="0" not-null="false"/>

  • how to make an array of arrays

    - by yuliya
    hi, how would you write an array of values to other array. In instance, I have a list of IPs and list of requests. I want to have something like [{ip1, request1}, {ip2, request2}, ....]. It's how I would do it, but sure obj will change every time and array will have all the time the same values. ArrayList array = new ArrayList(); Object[] obj = new Object[2]; for (int i=0; i<listSize; i++){ obj[0] = ipList.get(i).toString(); obj[1] = requestList.get(i); array.add(obj);

  • HTML Dynamic Number of Dropdowns

    - by Evilsithgirl
    I have this form on which I would like to create a dynamic number of dropdowns. I have a list of categorized applications which I would like each to have its own dropdown that submits data for each dropdown. The dropdown options will be the same for each. Here is my code. I am not sure how to pass the unique data to the server. As you can see I currently have an iteration over a list of applications that I would like to make each select in that iteration its own dropdown. Thanks in advance. <html:form action="/CategorizeApps.do"> <h3>Uncategorized</h3> <br/> Categorize each application using the dropdown menu then click categorize.<br/> <table class="list"> <thead> <tr class="controls"> <td><input type="submit" name="btnAction" value="Categorize"/></td> </tr> <tr class="fields"> <td>ID</td> <td>Name</td> <td></td> </tr> </thead> <tbody> <logic:iterate id="uncat" name="appsUncat" scope="session"> <tr class="hlist"> <td><bean:write property="id" name="uncat" scope="page"/></td> <td><bean:write property="name" name="uncat" scope="page"/></td> <td><select id="category" name="category"> <logic:iterate id="categories" name="Categories" scope="session"> <option value="<bean:write name="categories" property="id" scope="page"/>"><bean:write name="categories" property="name" scope="page"/></option> </logic:iterate> </select></td> </tr> </logic:iterate> </tbody> </table> </html:form>

  • Is it possible to establish default values for inherited fields in subclasses?

    - by Christian Mann
    I'm trying to establish a default value for inherited fields from superclasses. So, my class hierarchy is thus: Character - Enemy - Boss                 \                   - Hero Each Character has a public static char avatar to represent him on an ASCII playing field. How do I set a default value for the avatar of each class inherited from Character? Thank you!

  • Wicket: Where to add components? Constructor? Or onBeforeRender?

    - by gmallett
    I'm a Wicket newb. This may just be my ignorance of the Wicket lifecycle so please enlighten me! My understanding is that Wicket WebPage objects are instantiated once and then serialized. This has led to a point of confusion for me, see below. Currently I have a template class which I intend to subclass. I followed the example in the Wicket docs demonstrating how to override the template's behavior in the subclass: protected void onBeforeRender() { add(new Label("title", getTitle())); super.onBeforeRender(); } protected String getTitle() { return "template"; } Subclass: protected String getTitle() { return "Home"; } This works very well. What's not clear to me are the "best practices" for this. It seems like onBeforeRender() is called on every request for the page, no? This seems like there would be substantially more processing done on a page if everything is in onBeforeRender(). I could easily follow the example of the other Wicket examples and add some components in the constructor that I do not want to override, but then I've divided by component logic into two places, something I'm hesitant to do. If I add a component that I intend to be in all subclasses, should I add it to the constructor or onBeforeRender()?

  • Session scoped bean as class attribute of Spring MVC Controller

    - by Sotirios Delimanolis
    I have a User class: @Component @Scope("session") public class User { private String username; } And a Controller class: @Controller public class UserManager { @Autowired private User user; @ModelAttribute("user") private User createUser() { return user; } @RequestMapping(value = "/user") public String getUser(HttpServletRequest request) { Random r = new Random(); user.setUsername(new Double(r.nextDouble()).toString()); request.getSession().invalidate(); request.getSession(true); return "user"; } } I invalidate the session so that the next time i got to /users, I get another user. I'm expecting a different user because of user's session scope, but I get the same user. I checked in debug mode and it is the same object id in memory. My bean is declared as so: <bean id="user" class="org.synchronica.domain.User"> <aop:scoped-proxy/> </bean> I'm new to spring, so I'm obviously doing something wrong. I want one instance of User for each session. How?

  • Obtaining memory available to JVM at runtime

    - by Bo Tian
    I'm trying to sort a bunch of data such that that the size of data input to the program can be larger than the memory available to the JVM, and handling that requires external sort which is much slower than Quicksort. Is there any way of obtaining memory available to the JVM at runtime such that I could use in place sorting as much as possible, and only switch to Mergesort when data input is too large?
