[EJB 3.0] - "An SLSB doesn't have a home interface anymore" ?

by christophe.laumond

Hi all, I'm using Seam1.0.1GA with the JBoss AS 4.0.4GA provided with JEMSInstaller and for testing I'm using the testng-jdk15.jar provided with the TestNG Eclipse plugin. I have found this article describing EJB 3.0 in general : http://www.javaworld.com/javaworld/jw-08-2004/jw-0809-ejb-p2.html Below the part this post is about : anonymous wrote : | An SLSB doesn't have a home interface anymore?in fact, no EJB type requires it. The bean class may or may not implement a business interface. If it does not implement any business interfaces, a business interface will be generated using all the public methods. When I read that I think : "This is wonderful !" I have generated DAO class using the Hibernate tools in Eclipse. For example : | @Stateless | public class AccountantHome { | | private static final Log log = LogFactory.getLog(AccountantHome.class); | | @PersistenceContext | private EntityManager entityManager; | | public void persist(Accountant transientInstance) { | ... | } | | public void remove(Accountant persistentInstance) { | ... | } | | public Accountant merge(Accountant detachedInstance) { | ... | } | | public Accountant findById(long id) { | ... | } | } | So this generated class is perfect according to what it said in the article. But when I deploy it I get : anonymous wrote : | bean class has no local, webservice, or remote interfaces defined and does not implement at least one business interface | I don't understand why this occure. It fails in both JBoss AS and the Microcontainer + Embeddable EJB3 of TestNG. I had to create an interface and add the annotation @Local to the interface in order to get a correct deploy. Could you tell me what I have missed please ?

by gavin.king＠jboss.com

In the CVS version of Seam there is a new kind of @Factory method which can be used like this. Check the docs in CVS.

[JBossWS] - How do you set the transfer-encoding

by alanjonesbath

Is it possible to set what transfer-encoding that JBoss uses for its web service responses. Currently, all our responses appear to use chunked encoding, but we'd prefer to use something else that doesn't add extra characters into the response sent down the wire. If it is possible, could you suggest how, or point me in the direction of somewhere that explains it.

[Installation, Configuration & Deployment] - Re: Rolling over JBoss console log

by kaobe

Hi Ramdas, there are some errors in your configuration. First you finish the opening appender tag with "/>". That brings a SaxParseException. Then you have the param "Target" that is not possible for the FileAppender. Apart from that your configuration works for me.

[Beginners Corner] - Re: Looking up MessageDrivenBean/MessageListener

by kaobe

Hi Gabriel, may be that I misunderstand you, but you seem to mix MBean with Message Driven Bean. An MBean is a Managed Bean in the jmx server. The Message Driven Bean is an EJB used for message based communication. You should lookup your MBean with something like this: http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossMQ (look for the examples). There is an explanation of how to get an MDB and trigger it. I hope it helps!

[JBoss Seam] - Re: performance issues when using variables in business cont

by SunFire

weeee, that did it. Thanks alot! Maybe put a little note into the docs that in some cases where you combine business context with lots of component calls in a JSF page is it highly recommended that SeamManagedTransactions are used since else the container will open up a whole lot of small pointless transactions? Anyways, thanks again! :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3971488#3971488 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3971488

[Persistence, JBoss/CMP, Hibernate, Database] - JoinColumn annotation order

by rajuanye

Hi all :) I have been using ManyToMany annotation to connect two tables. I thought the order of 'JoinColumn', does not matter, however when I wrote: @ManyToMany(cascade = {CascadeType.PERSIST, CascadeType.MERGE}, fetch=FetchType.LAZY) @JoinTable(name="profile_group_link" , inverseJoinColumns = {@JoinColumn(name = "group_id")}, joinColumns = { @JoinColumn(name = "profile_id"),@JoinColumn(name = "population_id")}) It did not work ,so I changed the order: joinColumns = {@JoinColumn(name = "population_id"), @JoinColumn(name = "profile_id")}) and it worked perfect!!! Does any one knows why that happens? Do the order of the annotation change things? thanks Very confused individual View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3971487#3971487 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3971487

by mkislina

Scott, is it valid only for web-access? Is it possible to use connectors for EJB application clients access from different networks? Help is very appriciated.

[EJB 3.0] - Re: Persistence Manager in the JNDI

by roeladriaensens

the second problem is probably related to EJBTHREE-628 (Redeployment doesn't work with E-EJB3), which is already fixed for RC9.

[JBoss Seam] - Re: Multiple roles and accessing the DataModel

by denis-karpov

You should use it like this #{list}, because when you use @DataModel Seam outjected wrapper into the current context with name of the property (list in your case) Another way you should wrap it by yourself, only then you can use it the way #{YourBean.YourModel} View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3971484#3971484 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3971484
