  • Java focus question

    - by Albinoswordfish
    This may be a silly question I don't know. Is there a way to remove the highlighter to represent focus in a Java GUI? For example when you click on a button the text will have a slight rectangle around the text. Thank you

  • hibernate column uniqueness question

    - by Seth
    I'm still in the process of learning hibernate/hql and I have a question that's half best practices question/half sanity check. Let's say I have a class A: @Entity public class A { @Id @GeneratedValue(strategy=GenerationType.AUTO) private Long id; @Column(unique=true) private String name = ""; //getters, setters, etc. omitted for brevity } I want to enforce that every instance of A that gets saved has a unique name (hence the @Column annotation), but I also want to be able to handle the case where there's already an A instance saved that has that name. I see two ways of doing this: 1) I can catch the org.hibernate.exception.ConstraintViolationException that could be thrown during the session.saveOrUpdate() call and try to handle it. 2) I can query for existing instances of A that already have that name in the DAO before calling session.saveOrUpdate(). Right now I'm leaning towards approach 2, because in approach 1 I don't know how to programmatically figure out which constraint was violated (there are a couple of other unique members in A). Right now my DAO.save() code looks roughly like this: public void save(A a) throws DataAccessException, NonUniqueNameException { Session session = sessionFactory.getCurrentSession(); try { session.beginTransaction(); Query query = null; //if id isn't null, make sure we don't count this object as a duplicate if(obj.getId() == null) { query = session.createQuery("select count(a) from A a where a.name = :name").setParameter("name", obj.getName()); } else { query = session.createQuery("select count(a) from A a where a.name = :name " + "and a.id != :id").setParameter("name", obj.getName()).setParameter("name", obj.getName()); } Long numNameDuplicates = (Long)query.uniqueResult(); if(numNameDuplicates > 0) throw new NonUniqueNameException(); session.saveOrUpdate(a); session.getTransaction().commit(); } catch(RuntimeException e) { session.getTransaction().rollback(); throw new DataAccessException(e); //my own class } } Am I going about this in the right way? Can hibernate tell me programmatically (i.e. not as an error string) which value is violating the uniqueness constraint? By separating the query from the commit, am I inviting thread-safety errors, or am I safe? How is this usually done? Thanks!

  • Regular expressions and the question mark

    - by James P.
    I'm having trouble finding a regular expression that matches the following String. Korben;http://feeds.feedburner.com/KorbensBlog-UpgradeYourMind?format=xml;1 One problem is escaping the question mark. Java's pattern matcher doesn't seem to accept \? as a valid escape sequence but it also fails to work with the tester at myregexp.com. Here's what I have so far: ([a-zA-Z0-9])+;http://([a-zA-Z0-9./-]+);[0-9]+ Any suggestions?

  • Quick top level server language question.

    - by Shane
    Right, so if you have to decide on a server-side language for a distributed Linux-based server backend, would you choose: PHP Mono ASP.net Java As a C++ programmer, I'm thinking Java+Tomcat, but I'd love to hear experienced thoughts here, especially relating to debugging and IDE (likely Eclipse). Also, please, it's not a flame question. I'm seeing excellent sites written in all, I'm just thinking about the compile/debug/release cycle. Cheers, Shane

  • Android - Question on postDelayed and Threads

    - by Chris
    I have a question about postDelayed. The android docs say that it adds the runnable to the queue and it runs in the UI thread. What does this mean? So, for example, the same thread I use to create my layout is used to run the Runnable? What if I want it as an independent thread that executes while I am creating my layout and defining my activity? Thanks Chris

  • An interview question on conditional operator

    - by nthrgeek
    I recently encountered with this question: How to reduce this expression: s73?61:60;. The hint given was that Instead of using conditional operator we could use a simple comparison which will work fine. I am not sure but I think it is possible with some GCC extension,although I am unable to figure it out myself. EDIT:The whole expression is this : s-=s73?61:60
