  • Link to audio in XHTML/EPUB

    - by wxs
    I'm looking into synchronizing an ebook in epub format (so the content is in XHTML) to an audio file. I'm thinking of putting something along the lines of: <a class="audiolink" href="sound.ogg?t=1093"></a> into the body of the document, and then have a custom epub reader that recognizes those tags and synchronizes the audio accordingly. That does seem like a bit of a hack to me though, especially the use of a special class name. Does anyone have any pointers to how this may be done in a more standards-compliant manner (or somewhere where it has been done before)? Ebooks with audio annotation seem like an idea that may already be out there.

  • Strange problem with SEAM stateful session bean

    - by John
    Hi, I've got a staeful session bean. @Scope(ScopeType.SESSION) @Name("chuckNorrisBean") public class ChuckNorrisBean implements Serializable, ChuckNorris with some function public void roundHouseKick() { ... } interface @Local public interface ChuckNorris { public void roundHouseKick() { ... } } and calling them on a jsf .xhtml page using #{chuckNorrisBean.roundHouseKick} which works perfectly fine. However if I add the @Stateful annotation to the bean so it becomes @Stateful @Scope(ScopeType.SESSION) @Name("chuckNorrisBean") public class ChuckNorrisBean implements Serializable, ChuckNorris and the page will load with exceptions complainig about Exception during request processing:Caused by javax.servlet.ServletException with message: "#{chuckNorrisBean.roundHouseKick}: javax.el.MethodNotFoundException: //localhost/universe/earth.xhtml @41,65 action= "#{chuckNorrisBean.roundHouseKick}": Method not found: ChuckNorrisBean:a6gkg-w6das4-g8wmgh0y-1-g8woy0wo-4b.roundHouseKick()" Any advice on what might've went wrong with my chuckNorrisBean? The system is built on SEAM/richfaces. Thanks!

  • how can i unmarshall in jaxb and enjoy the schema validation without using an explicit schema file

    - by ekeren
    I am using jaxb for my application configurations I feel like I am doing something really crooked and I am looking for a way to not need an actual file or this transaction. As you can see in code I: 1.create a schema into a file from my JaxbContext (from my class annotation actually) 2.set this schema file in order to allow true validation when I unmarshal JAXBContext context = JAXBContext.newInstance(clazz); Schema mySchema = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI).newSchema(schemaFile); jaxbContext.generateSchema(new MySchemaOutputResolver()); // ultimately creates schemaFile Unmarshaller u = m_context.createUnmarshaller(); u.setSchema(mySchema); u.unmarshal(...); do any of you know how I can validate jaxb without needing to create a schema file that sits in my computer? Do I need to create a schema for validation, it looks redundant when I get it by JaxbContect.generateSchema ? How do you do this?

  • Django many to many annotations and filters

    - by dl8
    So I have two models, Person and Film where they're in a many to many relationship. My goal is to grab a film, and output the persons that have also appeared in at least 10 films. For example I can get the count individually by: >>> Person.objects.get(short__istartswith = "Matt Damon").film_set.count() 71 However, if I try to filter all the actors of a particular film out: >>> Film.objects.get(name__istartswith="Saving Private Ryan").actors.all().annotate(film_count=Count('film')).filter(film_count__gte=10) [] it returns an empty set since if I manually look at everyone's film_count it's 1, even though an actor such as Matt Damon (as seen above) has been in 71 films in my db. As you can see with this query, the annotation doesn't work: >>> Film.objects.get(name__istartswith="Saving Private Ryan").actors.all().annotate(film_count=Count('film'))[0].film_count 1 >>> Film.objects.get(name__istartswith="Saving Private Ryan").actors.all().annotate(film_count=Count('film'))[0].film_set.count() 7 and I can't seem to figure out a way to filter it by the film_set.count()

  • Hibernate Validator - Using properties in the constraints xml

    - by Avi Y
    Hi, I have just started using hibernate validator. I am creating the constraints in an XML file(not annotations). The only problem I am having is that I would like to use properties inside the constraints. For example: <bean class="MyBean" > <constraint annotation="javax.validation.constraints.Min"> <element name="value">{myProperty}</element> </constraint> </bean> and I would like to define these properties in a separate file. Do you think that's possible? Any help would be appreciated.

  • Session Management in Axis1.2

    - by venkat
    Hi, In our application we are using Axis1.2. Our service has one instance variable profileDataManager which is responsible to return set of profiles. The application has pagination to display only 25 profiles at a time. My requirement is the profileDataManager should be instantiated only once for respective client. On subsequent calls, it should use the existing object. For this i need the one service object should be created for user session.If a client sends another request, the service object created in previous call should be returned. On client side i am using Flex. In CXF webserice, my requirement is fulfilled with an annotation '@HttpSessionScope'. Is there away that i can get the abovementioned behavior in Axis? I have given the following trials. but no success added and modified the java client stub.setMaintainSession(true); The above didn't work for me.

  • BigDecimal precision not persisted with javax.persistence annotations

    - by dkaczynski
    I am using the javax.persistence API and Hibernate to create annotations and persist entities and their attributes in an Oracle 11g Express database. I have the following attribute in an entity: @Column(precision = 12, scale = 9) private BigDecimal weightedScore; The goal is to persist a decimal value with a maximum of 12 digits and a maximum of 9 of those digits to the right of the decimal place. After calculating the weightedScore, the result is 0.1234, but once I commit the entity with the Oracle database, the value displays as 0.12. I can see this by either by using an EntityManager object to query the entry or by viewing it directly in the Oracle Application Express (Apex) interface in a web browser. How should I annotate my BigDecimal attribute so that the precision is persisted correctly? Note: We use an in-memory HSQL database to run our unit tests, and it does not experience the issue with the lack of precision, with or without the @Column annotation.

  • Using Mapkit to create a local searchable Map

    - by Digital D
    Using MapKit as a base, I'm planning on adding a map to a project with 'local search' capabilities. I think 'local search' describes the feature I want to design into the map. Here is my vision. The map is displayed on the bottom half of a view. The user's current location is highlighted by default. When the user pushes the 'search' button annotation pins drop onto the map. The search is programmatically fixed to a certain item....for example supermarkets. So supermarkets in a 5 mile radius of the user's current location will populate the map. How would I add this local search feature to the already amazing MapKit? I've learned an incredible amount as a new developer in the last few months, and look forward to learning googles...correction googols more. Thanks in anticipation.

  • Are there macro facility for Java or C#?

    - by h2g2java
    Macros are useful. Therefore, I occasionally bemoan the absence of macros in Java and C#. Macros allow me to force in-line but allow me the code-manageability of non-macro code. Is there any Java- or C#-based project/product somewhere out there that effectively allow macros or specifying in-line expansion. I am thinking of something like @macro public void hello(int x){ ... } or when I call a method, an @inline annotation preceding the call would effect the called-method to be in-lined. or, should I need to know that I should just trust the compiler to make the best the decision for me that at the best of its analysis it might in-line a call. I hope this question will not lead to debating the pro/cons/usefulness of macros.

  • How can I specifiy JUnit test dependencies?

    - by Egon Willighagen
    Our toolkit has over 15000 JUnit tests, and many tests are known to fail if some other test fails. For example, if the method X.foo() uses functionality from Y.foo() and YTest.testFoo() fails, then XTest.testFoo() will fail too. Obviously, XTest.testFoo() can also fail because of problems specific to X.foo(). While this is fine and I still want both tests run, it would be nice if one could annotate a test dependency with XTest.testFoo() pointing to YTest.testFoo(). This way, one could immediately see what functionality used by X.foo() is also failing, and what not. Is there such annotation available in JUnit or elsewhere? Something like: public YTests { @Test @DependsOn(method=org.example.tests.YTest#testFoo) public void testFoo() { // Assert.something(); } }

  • Configure Hibernate validation for bean

    - by sergionni
    Hi. I need to perform validation based on SQL query result. Query is defined as annotation - as @NamedQuery in my entity bean. According to Hibernate documentation(doc), there is possibility to validate bean on following operations: pre-update pre-insert pre-delete looks like: <hibernate-configuration> <session-factory> ... <event type="pre-update"> <listener class="org.hibernate.cfg.beanvalidation.BeanValidationEventListener"/> </event> <event type="pre-insert"> <listener class="org.hibernate.cfg.beanvalidation.BeanValidationEventListener"/> </event> <event type="pre-delete"> <listener class="org.hibernate.cfg.beanvalidation.BeanValidationEventListener"/> </event> </hibernate-configuration> The question is how to connect my bean with the validation configuration, described above.

  • Django and conditional aggregates

    - by piquadrat
    I have two models, authors and articles: class Author(models.Model): name = models.CharField('name', max_length=100) class Article(models.Model) title = models.CharField('title', max_length=100) pubdate = models.DateTimeField('publication date') authors = models.ManyToManyField(Author) Now I want to select all authors and annotate them with their respective article count. That's a piece of cake with Django's aggregates. Problem is, it should only count the articles that are already published. According to ticket 11305 in the Django ticket tracker, this is not yet possible. I tried to use the CountIf annotation mentioned in that ticket, but it doesn't quote the datetime string and doesn't make all the joins it would need. So, what's the best solution, other than writing custom SQL?

  • Visualize compiler warnings

    - by christoffer
    I'm looking for a way to visualize compiler warnings and remarks, by annotating or otherwise showing which lines cause a report. This is much like a modern IDE like NetBeans or Eclipse already does, but I'd like to take output from several compilers (and other static code analysis tools) at once, and create one single annotation in order to get a better overview. The rationale is that we've seen some problems go completely undetected by, say, Visual Studio 2005, but accurately detected with a proprietary ARM compiler, and vice versa. Cross-referencing warnings could potentially locate problems better, but doing so completely manually is infeasible. Have you heard of such a tool? Could an open-source IDE like Eclipse be extended to use several compilers at once, or has it already been done?

  • How to serialize Java primitives using Jersey REST

    - by Olvagor
    In my application I use Jersey REST to serialize complex objects. This works quite fine. But there are a few method which simply return an int or boolean. Jersey can't handle primitive types (to my knowledge), probably because they're no annotated and Jersey has no default annotation for them. I worked around that by creating complex types like a RestBoolean or RestInteger, which simply hold an int or boolean value and have the appropriate annotations. Isn't there an easier way than writing these container objects?

  • How do I prevent JAXB from binding superclass methods of the @XmlRootElement when marshalling?

    - by Matt Fisher
    I have a class that is annotated as the @XmlRootElement with @XmlAccessorType(XmlAccessType.NONE). The problem that I am having is that the superclass's methods are being bound, when I do not want them to be bound, and cannot update the class. I am hoping there is an annotation that I can put on the root element class to prevent this from happening. Example: @XmlRootElement @XmlAccessorType(XmlAccessType.NONE) public class Person extends NamedObject { @XmlElement public String getId() { ... } } I would expect that only the methods annotated @XmlElement on Person would be bound and marshalled, but the superclass's methods are all being bound, as well. The resulting XML then has too much information. How do I prevent the superclass's methods from being bound without having to annotate the superclass, itself?

  • ASP.NET MVC & ADO.NET Entity Framework clientside validation

    - by JK
    Using aspnet mvc2 with the model auto-generated by entity framework: Is it possible to tell entity framework to auto-annotate all fields? eg: If database field says not null then add [Required] If DB field is a nvarchar(x) then add [StringLength(x)] And so on? What if the field name contains the string "email" eg CustomerEmail - can I get EF to auto-annotate that with an appropriate annotation ([Regex()] maybe) As I understand it, if the model fields are annotated, and I use both Html.ValidationMessageFor() and use if (ModelState.IsValid) in my controller, then that is all I need to do to have basic clientside input validation working? Thanks

  • Specifying distinct sequence per table in Hibernate on subclasses

    - by gutch
    Is there a way to specify distinct sequences for each table in Hibernate, if the ID is defined on a mapped superclass? All entities in our application extend a superclass called DataObject like this: @MappedSuperclass public abstract class DataObject implements Serializable { @Id @GeneratedValue(strategy = GenerationType.SEQUENCE) @Column(name = "id") private int id; } @Entity @Table(name = "entity_a") public class EntityA extends DataObject { ... } @Entity @Table(name = "entity_b") public class EntityB extends DataObject { ... } This causes all entities to use a shared sequence, the default hibernate_sequence. What I would like to do is use a separate sequence for each entity, for example entity_a_sequence and entity_b_sequence in the example above. If the ID were specified on the subclasses then I could use the @SequenceGenerator annotation to specify a sequence for each entity, but in this case the ID is on the superclass. Given that ID is in the superclass, is there a way I can use a separate sequence for each entity — and if so, how? (We are using PostgreSQL 8.3, in case that's relevant)

  • Exceptions and web services

    - by Schildmeijer
    Im using the standard java ws implementation shipped with e.g. java6 (javax.jws.*). I have the following: import javax.jws.*; @WebService(name="Widget") public interface Widget { @WebMethod public @WebResult String getGadget(@WebParam(name = "id") long id) throw MyOwnException; } Is this possible? Do I have to annotate MyOwnException with e.g the @WebFault annotation? During my initial tests I also noticed that, on the client side, the autogenerated MyOwnException was renamed to MyOwnException_Exception and wrapped the "original" MyOwnException. Or if this is a bad idea, are there any recommended Exceptions to throw from a webservice like this?

  • iOS6 MKMapView using a ton of memory, to the point of crashing the app, anyone else notice this?

    - by Jeremy Fox
    Has anyone else, who's using maps in their iOS 6 apps, noticing extremely high memory use to the point of receiving memory warnings over and over to the point of crashing the app? I've ran the app through instruments and I'm not seeing any leaks and until the map view is created the app consistently runs at around ~3mb Live Bytes. Once the map is created and the tiles are downloaded the Live Bytes jumps up to ~13mb Live Bytes. Then as I move the map around and zoom in and out the Live Bytes continuos to climb until the app crashes at around ~40mb Live Bytes. This is on an iPhone 4 by the way. On an iPod touch it crashes even earlier. I am reusing annotation views properly and nothing is leaking. Is anyone else seeing this same high memory usage with the new iOS 6 maps? Also, does anyone have a solution?

  • Calculated property with JPA / Hibernate

    - by Francois
    My Java bean has a childCount property. This property is not mapped to a database column. Instead, it should be calculated by the database with a COUNT() function operating on the join of my Java bean and its children. It would be even better if this property could be calculated on demand / "lazily", but this is not mandatory. In the worst case scenario, I can set this bean's property with HQL or the Criteria API, but I would prefer not to. The Hibernate @Formula annotation may help, but I could barely find any documentation. Any help greatly appreciated. Thanks.

  • Scala and the Java Memory Model

    - by Ben Lings
    The Java Memory Model (since 1.5) treats final fields differently to non-final fields. In particular, provided the this reference doesn't escape during construction, writes to final fields in the constructor are guaranteed to be visible on other threads even if the object is made available to the other thread via a data race. (Writes to non-final fields aren't guaranteed to be visible, so if you improperly publish them, another thread could see them in a partially constructed state.) Is there any documentation on how/if the Scala compiler creates final (rather than non-final) backing fields for classes? I've looked through the language specification and searched the web but can't find any definitive answers. (In comparison the @scala.volatile annotation is documented to mark a field as volatile)

  • org.hibernate.annotations.Entity not being picked up by Hibernate 3.6

    - by user1317764
    I am using hibernate 3.6.7 I am using annotated classes. My classes were annotated with org.hibernate.annotations.Entity. Added the classes to configuration using configuration.addAnnotatedClass() method. Hibernate does not seem to pick it up. Stuff works fine if I use the standard jpa Entity annotation. What am I missing? I know that the classes have been deprecated in the Hibernate 4.x releases with the advent of newer annotations to configure stuff like dynamic-insert and dynamic-updates. I am not using any XML configuration file. I am setting up configuration with a properties file and using java apis.
