  • Cannot capture TouchEvent.UP in Blackberry

    - by Nandu
    I am working on a Scrollable Image field.I am handling TouchEvent.DOWN mTouchEvent.MOVE,TouchEvent.UP. Somehow control never goes to TouchEvent.UP section.How to capture the UP event. I have to findout the start and end points of the drag. My Code looks like this.. if (event == TouchEvent.DOWN && touchEvent.isValid()) { _xTouch = touchEvent.getX(1); _yTouch = touchEvent.getY(1); } else if(event == TouchEvent.UP && touchEvent.isValid()) { int x = touchEvent.getX(1); int y = touchEvent.getY(1); } else if (event == TouchEvent.MOVE && touchEvent.isValid()) { boolean result = scrollImage((touchEvent.getX(1) - _xTouch), (touchEvent.getY(1) - _yTouch)); _xTouch = touchEvent.getX(1); _yTouch = touchEvent.getY(1); //If scrolling occurred, consume the touch event. if (result) { return true; } else { return false; } } Thanks in advance.

  • Creating queries using Criteria API (JPA 2.0)

    - by Pym
    Hello there ! I'm trying to create a query with the Criteria API from JPA 2.0, but I can't make it work. The problem is with the "between" conditionnal method. I read some documentation to know how I have to do it, but since I'm discovering JPA, I don't understand why it does not work. First, I can't see "creationDate" which should appear when I write "Transaction_." I thought it was maybe normal, since I read the metamodel was generated at runtime, so I tried to use 'Foo_.getDeclaredSingularAttribute("value")' instead of 'Foo_.value', but it still doesn't work at all. Here is my code : public List<Transaction> getTransactions(Date startDate, Date endDate) { EntityManager em = getEntityManager(); try { CriteriaBuilder cb = em.getCriteriaBuilder(); CriteriaQuery<Transaction> cq = cb.createQuery(Transaction.class); Metamodel m = em.getMetamodel(); EntityType<Transaction> Transaction_ = m.entity(Transaction.class); Root<Transaction> transaction = cq.from(Transaction.class); // Error here. cannot find symbol. symbol: variable creationDate cq.where(cb.between(transaction.get(Transaction_.creationDate), startDate, endDate)); // I also tried this: // cq.where(cb.between(Transaction_.getDeclaredSingularAttribute("creationDate"), startDate, endDate)); List<Transaction> result = em.createQuery(cq).getResultList(); return result; } finally { em.close(); } } Can someone help me to figure this out? Thanks.

  • What is the best way to handle validity dates in applications ?

    - by user214626
    Hello, How do we model these objects ? Scenario 1: Price changes in a time period EffectiveDate ExpiryDate Price 2009-01-01 2009-01-31 800$ 2009-02-01 Null 900$ So, if the price changes to 910$ on 2009-02-15, then the system should automatically update the expiry date on the previous effective price to 2009-02-14, to keep it consistent. Scenario 2: No price specified between 2009-02-01 to 2009-02-28 EffectiveDate ExpiryDate Price 2009-01-01 2009-01-31 800$ 2009-03-01 Null 900$ So, if new price is specified for 2009-02-15 onwards , then the system should automatically set the expiry date on the record to be inserted to 2009-02-28, because already a record effective from 2009-03-01 exists. Please suggest an effective way to handle these scenarios to model my framework, or are there any frameworks around that can do this . Thanks

  • I create a JPanel and GridBagLayout within an object but when I get it in the main object, attributes are missing

When calling the functions in another file, it looks like I just get the JPanel (but without any labels or the layout or other GridBagLayout features). Help?

  • Is it possible to make web app proactive rather than reactive?

    - by Ari B.
    Web applications traditionally follow the request/response cycle, where a request is made by a user or another web app. However, I'm curious if it is possible to make a web app automatically initiate certain tasks upon it's deployment to a app server. For example, let's say we have a web app that retrieves and processes data. Is it possible to configure this app to automatically retrieve and process data when certain criteria are met, rather than needing a request from a user/another web app?

  • Get children count via HQL

    - by Thomas Lötzer
    Hi, I have a one-to-many mapping between a parent entity and child entities. Now I need to find the number of children associated with each parent for a list of parents. I am trying to do this with HQL but I am not sure how I can get the list of parents in there. Also, I don't know how I can return the entity itself and not just its ID. My current HQL query is: select new map(parent.id as parentId, count(*) as childCount) from Parent parent left join parent.children children group by parent.id but this only returns the ID and does not filter on specific parents. EDIT Based on Pascal's answer I have modified the query to select new map(parent as parent, count(elements(parent.children)) as childCount) from Parent parent group by parent That does work, but is prohibitively slow: 30 seconds instead of 400 ms on the same database.

  • How to prevent "Local transaction already has 1 non-XA Resource" exception?

    - by Zeratul
    Hi, I'm using 2 PU in stateless EJB and each of them is invoked on one method: @PersistenceContext(unitName="PU") private EntityManager em; @PersistenceContext(unitName="PU2") private EntityManager em2; @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW ) public void getCandidates(final Integer eventId) throws ControllerException { ElectionEvent electionEvent = em.find(ElectionEvent.class, eventId); ... Person person = getPerson(candidate.getLogin()); ... } @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW ) private Person getPerson(String login) throws ControllerException { Person person = em2.find(Person.class, login); return person; } Those methods are annotated with REQUIRES_NEW transcaction to avoid this exception. When I was calling these method from javaFX applet, all worked as expected. Now I'm trying to call them from JAX-RS webservice (I don't see any logical difference as in both cases ejb was looked up in initial context) and I keep getting this exception. When I set up XADatasource in glassfish 2.1 connection pools, I got nullpointer exception on em2. Any ideas what to try next? Regards

  • How to remove the file suffix/extension (.jsp and .action) using the Stripes Framework?

    - by Dolph Mathews
    I'm looking to use pretty / clean URL's in my web app. I would like the following URL: http://mydomain.com/myapp/calculator .. to resolve to: com.mydomain.myapp.action.CalculatorActionBean I tried overwriting the NameBasedActionResolver with: public class CustomActionResolver extends NameBasedActionResolver { public static final String DEFAULT_BINDING_SUFFIX = "."; @Override protected String getBindingSuffix() { return DEFAULT_BINDING_SUFFIX; } @Override protected List<String> getActionBeanSuffixes() { List<String> suffixes = new ArrayList<String>(super.getActionBeanSuffixes()); suffixes.add(DEFAULT_BINDING_SUFFIX); return suffixes; } } And adding this to web.xml: <servlet-mapping> <servlet-name>StripesDispatcher</servlet-name> <url-pattern>*.</url-pattern> </servlet-mapping> Which gets me to: http://mydomain.com/myapp/Calculator. But: A stray "." is still neither pretty nor clean. The class name is still capitalized in the URL..? That still leaves me with *.jsp..? Is it even possible to get rid of both .action and .jsp?

  • Emulating HTTP POST via httpclient 3.x for multi options

    - by Frankie Ribery
    I want to emulate a HTTP POST using application/x-www-form-urlencoded encoding to send a option group that allows multiple selections. <select name="groups" multiple="multiple" size="4"> <option value="2">Administration</option> <option value="1">General</option> </select> Does adding 2 NameValuePairs (NVP) with the same name work ? My serverside log shows that only the first NVP was received. e.g PostMethod method = ...; NameValuePair[] nvpairs = { new NameValuePair( "groups", "2" ); new NameValuePair( "groups", "1" ); }; method.addParameter( nvpairs ); Only the groups=1 parameter was received. Thanks

  • controlling threads flow

    - by owca
    I had a task to write simple game simulating two players picking up 1-3 matches one after another until the pile is gone. I managed to do it for computer choosing random value of matches but now I'd like to go further and allow humans to play the game. Here's what I already have : http://paste.pocoo.org/show/201761/ Class Player is a computer player, and PlayerMan should be human being. Problem is, that thread of PlayerMan should wait until proper value of matches is given but I cannot make it work this way. Logic is as follows: thread runs until matches equals to zero. If player number is correct at the moment function pickMatches() is called. After decreasing number of matches on table, thread should wait and another thread should be notified. I know I must use wait() and notify() but I can't place them right. Class Shared keeps the value of current player, and also amount of matches. public void suspendThread() { suspended = true; } public void resumeThread() { suspended = false; } @Override public void run(){ int matches=1; int which = 0; int tmp=0; Shared data = this.selectData(); String name = this.returnName(); int number = this.getNumber(); while(data.getMatches() != 0){ while(!suspended){ try{ which = data.getCurrent(); if(number == which){ matches = pickMatches(); tmp = data.getMatches() - matches; data.setMatches(tmp, number); if(data.getMatches() == 0){ System.out.println(" "+ name+" takes "+matches+" matches."); System.out.println("Winner is player: "+name); stop(); } System.out.println(" "+ name+" takes "+matches+" matches."); if(number != 0){ data.setCurrent(0); } else{ data.setCurrent(1); } } this.suspendThread(); notifyAll(); wait(); }catch(InterruptedException exc) {} } } } @Override synchronized public int pickMatches(){ Scanner scanner = new Scanner(System.in); int n = 0; Shared data = this.selectData(); System.out.println("Choose amount of matches (from 1 to 3): "); if(data.getMatches() == 1){ System.out.println("There's only 1 match left !"); while(n != 1){ n = scanner.nextInt(); } } else{ do{ n = scanner.nextInt(); } while(n <= 1 && n >= 3); } return n; } }

  • How to get IzPack tocheck for an existing version of the software?

    - by bguiz
    Hi, I have an application for which we use IzPack to create the installer. The installer is working fine in its current state, however, I need to add functionality that enables it to check whether an existing version of the software has been installed. I understand IzPack supports this out of the box using its CheckedHelloPanel, unfortunately that only works for Windows, as it appears to depend on the windows registry. Is there a way to configure IzPack such that it is able to detect existing installations? I need to be able to detect whether there is one and merely display a message notifying the user... Bonus points for how to give the user the option to trigger the uninstaller of the existing installation. Assume that the software will only be installed using the new installer IzPack only: please do not suggest alternatives, as we cannot change that now If you suggest using <validator>, please include a code sample of the validator class, because I have considered this, but don't know where to start

  • How can I Convert XML to an Object using Spring 3.0 mvc while making RESTful request

    - by brock
    Hi, I'm using the Spring 3.0 RC1 framework and I'm currently testing out Spring mvc. I wanted to use Spring mvc to handle restful requests. I have set up my controller to handle the URI request. I am passing in xml with the request. So on the controller I have a method like follows: public void request(RequestObject request) { doSomething(); } I am having a hard time converting the xml to the RequestObject. I haven't seen much documentation on this and I was wondering if anyone could point me in the right direction. I'm guess that you would have to annotate the RequestObject using JAXB or something in order to tell Spring to convert the xml file to RequestObject but I'm not sure. Thanks for all of your help!!

  • Why do transfer objects need to implement Serializable?

    - by smaye81
    I realized today that I have blindly just followed this requirement for years without ever really asking why. Today, I ran across a NotSerializableException with a model object I created from scratch and I realized enough is enough. I was told this was because of session replication between load-balanced servers, but I know I've seen other objects at session scope that do not implement Serializable. Is this the real reason?

  • Computing unique index for every poker starting hand

    - by Aly
    As there are 52 cards in a deck we know there are 52 choose 2 = 1326 distinct matchups, however in preflop poker this can be bucketed into 169 different hands such as AK offsuit and AK suited as whether it is A hearts K hearts or A spade K spades it makes no difference preflop. My question is, is there a nice mathematical property in which I can uniquely index each of these 169 hands (from 0 to 168 preferably). I am trying to create a look up table as a double[][] = new double [169][169] but have no way of changing a hand representation such as AKs (an Ace and a King of the same suit) to a unique index in this array.

  • HyperJAXB and IDREFs

    - by finrod
    I have eventually managed to fiddle HyperJAXB so that when XSD has complexType A and this has an IDREF to complexType B, then HyperJAXB will generate @OneToOne JPA annotations between the the two generated entities. However now I'm facing another problem: the XSD has complex type X that can IDREF to either complex type Y or complex type Z. In the end, I need instance of complex type X contain reference to either instance of class Y or class Z. Do you have any wild ideas how can this be done without manual alterations to the generated classes? And at the same time to make sure these entities are marshalled to a correct XML? How about using the JAXB plugin that allows generating classes so that they implement a particular interface? Could that lead anywhere?

  • Vehicle 2 Vehicle Communication Questions

    - by pinnacler
    I have a rare opportunity to meet the man in charge of implementing vehicle 2 vehicle communication for the US Department of Transportation with 2 others in a few hours. Do YOU have any questions for him? I know this is a little outside the normal, but this is a 'reverse' thread and I felt he has some great knowledge on the subject that I want to share with this community. I'll post his answers later today to his questions. Ask about V2V implementation, privacy issues, use cases, or if you've thought of a great way to use V2V and want me to share it with him, he can at least think about it. He is in charge of panel that creates the standard. Or anything else...
