ejb-3.0

I would like to know how can I access the file system from an EJB 3 bean? I searched the Internet on the subject and haven't found a good answer. Some suggest using the java.io/java.nio even though the specification prohibits this usage. Most application servers seem to allow the access to this API anyway. Another idea would be to use an JCA connector to access the file system or a LDAP directory. What I want to do this to avoid the use of BLOB in the database when a simple file would be a much better solution in terms of performance and used resources. How would you solve this problem? The

Using Glassfish, I can setup a string jndi entry: JNDI name: "com/xyzcompany/echo/EchoServiceBean/viewName" Factory Class: org.glassfish.resources.custom.factory.PrimitivesAndStringFactory Properties: value="Testing123" I can then inject this container configured string into my EJB: @Resource(lookup = "com/xyzcompany/echo/EchoServiceBean/viewName") String viewName; The lookup= appears to internally do an InitialContext.lookup(...). However, this uses ejb3.1, but unfortunately my prod environment is only ejb3.0. I guess i'm trying to figure out is there a way to use @Resource(name=) or

I have a stateless bean something like: @Stateless public class MyStatelessBean implements MyStatelessLocal, MyStatelessRemote { @PersistenceContext(unitName="myPC") private EntityManager mgr; @TransationAttribute(TransactionAttributeType.SUPPORTED) public void processObjects(List<Object> objs) { // this method just processes the data; no need for a transaction for(Object obj : objs) { this.process(obj); } } @TransationAttribute(TransactionAttributeType.REQUIRES_NEW) public void process(Object obj) { // do some work with obj that must be in the scope of a transaction this.mgr.merge(obj); // ..

Starting a new project using EJB 3 / JPA, mainly stateless session beans and batch jobs. I've used JUnit in the past on standard Java webapps and it seemed to work pretty well. In EJB2 unit testing was a pain and required a running container such as JBoss to make the calls into. Now that we're going to be working in EJB3 / JPA I'd like to know what companies are using to write and run these tests. Are Junit and JMock still considered relevant or are there other newer frameworks that have come around that we should investigate? ewernli IMHO, yes they are still relevant. With EJB3, you can test

Which online resources , tutorials or books can you recommended to get started with unit testing J2EE / EJB3 applications? So far I have found ejb3unit , Jakarta Cactus (retired 2011/08) and the Maven Cargo plugin . It would be helpful if there are complete working examples, ready to run. Target containers are the open source products GlassFish , JBoss and Apache OpenEJB .

We have some staleless EJBs (EJB3) deployed on a GlassFish 2 server that expose some of their methods as webservices via the @Webmethod annotation. Now we want to secure these webservice methods so that only authenticated clients can call it. What would be a good way to achieve this? Like the good reverend said. Example below uses a file realm for authentication. @Stateless @WebService(name = "MyAppServices") @RolesAllowed({"user"}) public class ItemEJB { ... } You will also need sun-ejb-jar.xml e.g. <sun-ejb-jar> <security-role-mapping> <!-- as defined in @RolesAllowed --> <role-name>user<

I've made a mavenized web application with spring, spring security... Now, I want to add ejb module for database access, I was looking on the internet but I didn't find something clear because it's my first time with EJB. I want to use something like @EJB in my controller like" @Stateless(name = "CustomerServiceImpl") public class CustomerServiceImpl implements CustomerService @EJB private MyEjb myEjb; and how can I configure it in spring context if there is a tutorial or any other help. It will be great and thank you Vishal Akkalkote To inject your ejb 3 bean in spring bean you can follow
