Yes exploded means than instead of deploying a WAR/EAR file to your application server to test your application you point your application server at a folder containing the unzipped (exploded) contents of what would be inside the WAR/EAR file. This makes development quicker as most application servers support Hot Deploy where you can change the … Read more
For EJB and JAR packaging you should place the beans.xml in src/main/resources/META-INF/. For WAR packaging you should place the beans.xml in src/main/webapp/WEB-INF/. Remember that only .java files should be put in the src/main/java and src/test/java directories. Resources like .xml files should be in src/main/resources.
I too couldn’t see the tutorial files in the update tool. The download link given by shurik2533 are the tutorial files for JavaEE5, not JavaEE6. Working on what John put I downloaded the files from the svn repository using: $ svn export https://svn.java.net/svn/javaeetutorial~svn JavaEE6tutorial/ To download only the examples: $ svn export https://svn.java.net/svn/javaeetutorial~svn/branches/javaee-tutorial-6/examples/ JavaEE6TutorialExamples
If your class does not have an @XmlRootElement annotation then you can wrap it in an instance of JAXBElement. If you generated your classes from an XML Schema then the generated ObjectFactory may have a convenience method for you. I have written more about this use case on my blog:
It depends on how you configured it (or lets say, you can configure a different behaviour). In a Web application you will use the ThreadLocalSecurityContextHolderStrategy which interacts with SecurityContextPersistenceFilter. The Java Doc of SecurityContextPersistenceFilter starts with: Populates the {@link SecurityContextHolder} with information obtained from the configured {@link SecurityContextRepository} prior to the request and stores it … Read more
Furthermore, @Resource annotation might not work. Try this @javax.ws.rs.core.Context ServletContext context; The injection doesn’t happen until you hit the service method public class MyService { @Context ServletContext context; public MyService() { print(“Constructor ” + context); // null here } @GET @Path(“/thing”) { print(“in wizard service ” + context); // available here
Let me take a crack at this. First of, I’ve written some on this subject in Using an ORM or plain SQL?. Specifically to address your points: Learning Curve/Ease of Use Ibatis is about SQL. If you know SQL the learning curve for ibatis is trivial. Ibatis does some things on top of SQL such … Read more
How about this? public enum RoleType { STUDENT(Names.STUDENT), TEACHER(Names.TEACHER), DEANERY(Names.DEANERY); public class Names{ public static final String STUDENT = “Student”; public static final String TEACHER = “Teacher”; public static final String DEANERY = “Deanery”; } private final String label; private RoleType(String label) { this.label = label; } public String toString() { return this.label; } } … Read more
To set a session-timeout that never expires is not desirable because you would be reliable on the user to push the logout-button every time he’s finished to prevent your server of too much load (depending on the amount of users and the hardware). Additionaly there are some security issues you might run into you would … Read more
I am the author of SimpleCaptcha. While I would recommend — for humanity’s sake — using ReCaptcha where you can, I provided SimpleCaptcha because some organizations have policies which prohibit libraries like ReCaptcha. SimpleCaptcha is meant to be entirely stand-alone, with no external dependencies: as long as you are in a J2EE container, you should … Read more
