EJB 3.0 AND Eclipse

Hi,
I'm looking for a good tutorial on eclipse and ejb 3.0. I started using the book Beginning Java EE 5: From Novice to Professional:
http://www.apress.com/book/view/1590594703
however I have come across a problem. I cant seem to get the example for a setting up a simple stateless session bean running. I'm using eclipse so I thought I could refer to this tutorial on eclipse;
http://www.eclipse.org/webtools/community/tutorials/ejbtutorial/buildingejbs.html
however this tutorial seems to be using a different version of eclipse or wtp and as a result it has many different options. I'm left a bit uncertain as to what I'm supposed to do to build an EJB.
Can someone give me an extremely simple example of creating a stateless session bean in EJB 3.0?

Check this one:

Building J2EE Applications using JBOSS and ECLIPSE 3.0

Hi all
i am trying to deploy a J2EE application using JBOSS3.2.5 and Eclipse 3.0.
I have written the EJB bean, home, remote and a test JSP page. Can someone tell me the exact procedure...step by step ways to deploy the JBOSS server and run my application.
My package structure is
MyProject
ejb
client
Servlet.java
server
Bean.java
shared
home.java
remote.java
please tell the various jar files that i must include. Kindly give information about the directory structure, the xml file details and the WAR file generation
Thankz in advance
Arun :)

That is a lot of stuff! At a basic level, you can create an EAR file and put it in the JBoss auto-deployment directory. In the EAR file you should have a WAR file for the web component and a JAR file for the EJB component. And inside each archive there should be a valid deployment descriptor that contains configuration data for the component. When you start up JBoss, the application will be deployed and accessible via web browser, or there will be error messages written to the server log.

JBoss and Eclipse Problem

Hi @ all,
i'm trying to learn J2EE technology with jboss and eclipse dev.kit.
I use the Jboss/eclipse tutorial (http://prdownloads.sourceforge.net/jboss/Tutorial-1.3.0.pdf)
but there are several problems with the ear-file.
This error will be processed if I try to deploy the package to the jboss

Hi, I ran into Sam problem. I have the Eclipse 3.1.0, JBOSS 4.0.1sp1, JBoss-IDE 1.3.0 running under JDK 1.5.0.02. It appers for sum resion that the jboss-web.xml is not getting the name of the �<ejb-ref-name></ejb-ref-name>�. if I manually add the name so it looks like this: �<ejb-ref-name>ejb/Fibo</ejb-ref-name>� the project deploys. I am new to this as well and am not shore what needs to be changed to fix this in the build. I am thinking it�s a problem in the way XDoclet parses the source for the META DATA.

Problem with "package-info.java" using EJB 3.0 and OC4J

Hi all.
I already posted this question on JDeveloper forum, but didn't get any answer,
so I'll try posting here.
Anyway, I'm new both to JDeveloper and J2EE,
so I'm trying out examples for EJB 3.0, and I got stuck at "Use Security Annotations with EJB 3.0"
(http://www.oracle.com/technology/tech/java/oc4j/ejb3/howtos-ejb3/howtoejb30security/doc/how-to-ejb30-security-ejb.html).
Example code is working perfectly, if one builds it using Ant, but I'm importing all examples into JDeveloper (or at least I'm trying to :))
JDeveloper can't build file "package-info.java" containing following code:
@javax.annotation.security.SecurityRoles(roleNames={"superuser", "user"})
package oracle.ejb30;I'm getting following output in "Compiler - Log" window:
Error(2,1): 'class', 'interface', or 'enum' expected.
Help much appreciated...
platform used:
Windows XP SP2
JDeveloper Studio (Version 10.1.3, Build 3412)
JDK 1.5_06
OC4J 10.1.3 developer preview 4 (standalone version)

Since you're using EJBs, you can use JTA and can skip the getTransaction() calls. If you want to use getTransaction().begin() and commit(), then make sure that your EntityManager is resource-local. The configuration for this is in persistence.xml. Set a transaction-type of RESOURCE_LOCAL rather than JTA.

Ejb 3.0 and JDeveloper

If I drag and drop tables with One to one mapping in an ejb diagram in JDeveloper (one table have having the foreign key as the primary key). If I create ejb 2.1 beans it makes makes a One To One mapping between the entity beans created and if I drop them as ejb 3.0 it makes a OneToMany mapping. this is what I get for the same tables.
for ejb 2.1
<ejb-relation>
<ejb-relation-name>Envincidents - Incidents</ejb-relation-name>
<ejb-relationship-role>
<ejb-relationship-role-name>Envincidents has one Incidents</ejb-relationship-role-name>

<multiplicity>One</multiplicity>

for ejb 3.0
Envincidents

@ManyToOne(targetEntity="mypackage.Incidents")
@JoinColumn(name="ENVINCIDENTS.INCIDENTS_ID", referencedColumnName="INCIDENTS.ID")
public Incidents getIncidents() {
return incidents;
public void setIncidents(Incidents incidents) {
this.incidents = incidents;
Incidents
@OneToMany(targetEntity="mypackage.Envincidents")
@JoinColumn(name="ENVINCIDENTS.INCIDENTS_ID", referencedColumnName="INCIDENTS.ID")
public Collection<Envincidents> getEnvincidentsCollection() {
return envincidentsCollection;
public void setEnvincidentsCollection(Collection<Envincidents> envincidentsCollection) {
this.envincidentsCollection = envincidentsCollection;
public Envincidents addToEnvincidentsCollection(Envincidents envincidents) {
getEnvincidentsCollection().add( envincidents );
envincidents.setIncidents( this );
return envincidents;
public Envincidents removeFromEnvincidentsCollection(Envincidents envincidents) {
getEnvincidentsCollection().remove( envincidents );
envincidents.setIncidents( null );
return envincidents;
this causes the following problem.
Exception Description: Multiple writable mappings exist for the field [ENVINCIDE
NTS.INCIDENTS_ID]. Only one may be defined as writable, all others must be spec
ified read-only.
which I have already reported.
I know this is a minor inconvenience and I can hand edit the entity beans and make them one to one for ejb 3.0. But would be to good advantage to have a consistent "dropping of tables" for ejb 2.1 and 3.0. So one can have a similar behavior of entity beans created from tables using ejb 2.1 and 3.0.

I guess this could be desirable if migrating from ejb 2.1 to 3.0 if one has already designed the database.

Ejb 3.0 and webservices

Hello everybody?
Does everybody know if i can create a web service from an ejb 3.0 stateless session inside jdeveloper 10 g 10.1.3 (using a wizard for example)?
Thank you

It's almost too easy to need a wizard - try this:
Trhough your project properties add the JSR-181 Web Service library
In your session bean type @Web (at the top of the class or above a method) and you'll be prompted to import javax.jws.WebMethod (using Alt-Enter) then you can select the appropriate tag (@WebService for all methods to be published, @WebMethod at the individual method level, etc.)
Then deploy your EJB as normal and voila! See the deployed EJB and Web Service

Ejb-jar.xml and orion-ejb-jar.xml configuration issue

Chris,
We have an application that uses the Oracle 10g Application Server and WebSphere MQ v5.3 w/ fixpack 9.
Our application is a J2EE messaging system which essentially consists of Message Driven Beans, the EJB
realization of the J2EE Java Message Service (JMS) API. Our application has Message Driven Beans which
listen to queues and send messages to queues -- a simple messaging system. Currently we can listen to queues, but
cannot send messages to queues in the Oracle 10g Application Server environment.
Any J2EE application server has its own implementation of Java Naming Directory Interface (JNDI) API that
deployed J2EE applications utilize to lookup resources such as Data Sources, JMS Destinations (i.e. MQ Queue),
JMS QueueConnectionFactories (i.e. MQ QManagers).
Our application uses the 3rd party JMS Provider, WebSphere MQ.
MQ ships with a JMSAdmin tool which allows one to create JMS administered objects (i.e. objects a java
application searches for in some JNDI directory) that reside in some JNDI context. We create a JNDI context for
MQ resources, queues and QManagers. We configure the MQ provided
JMSAdmin tool with two property name/value pairs:
PROVIDER_URL=file:/opt/mqm/JNDI-Directory
INITIAL_CONTEXT_FACTORY=com.sun.jndi.fscontext.RefFSContextFactory
A resultant .bindings file is created in /opt/mqm/JNDI-Directory which represents our JDNI context
containing our JMS administered objects. A standalone java application that needs to directly access this
JNDI context can simply conduct a JNDI lookup on the following context: "java:comp/resource/MQSeries/". An
example of how a standalone application would lookup a JMS administered object named "qNumber1" would be to
lookup "java:comp/resource/MQSeries/qNumber1". This lookup would result in the standalone java application
having a JMS reference to an MQ Queue.
There is a major difference in how an enterprise EJB application deployed into a J2EE Container (Oracle 10g App Server)
conducts a JNDI lookup on a 3rd party resource such as MQ as a JMS Provider. A typical EJB application deployed
into a J2EE container as an .ear (enterprise archive) file has implicit access to the application server's own
JNDI context. This JNDI context is usually "java:comp/env/". Looking up the Application Server's own Data Source or
it's own JMS Resources is easy. An application that needs references to these Application Server provided resources
simply conducts a lookup for "java:comp/env/jms/someQ" or "java:comp/env/jdbc/myDataSource".
The problem we face is mapping our MQ JNDI context to the Oracle App Server's own JNDI context. We believe this is
accomplished through mappings defined in both the ejb-jar.xml (EJB Descriptor) and the application server specific
counterpart, orion-ejb-jar.xml. Note that Oracle 10g Application Server uses the popular orion J2EE container for
hosting J2EE enterpise applications.
Our Message Driven Beans (MDBs)currently listen to the Queue at the JNDI location "prodQ". Our problem is that we cannot
get our MDB to send messages to any queues. Note that the MQ implementation of the queues and Queue Managers work
flawlessly with standalone java applications. It's safe to say that the MQ objects are working.
We are looking for a solid example of how the ejb-jar.xml and the orion-ejb-jar.xml map 3rd party JMS provider
JNDI locations to the App Server's JNDI context.
Below is how we have attempted to configure our own ejb-jar.xml and orion-ejb-jar.xml:

If you look at the contents of a deployment plan (Plan.xml) when you have it generated

    </module-descriptor>
</module-override>
</deployment-plan>You can see which files can be external and which can be not. The weblogic-ejb-jar.xml can be external
but in this case you need a deployment plan to point weblogic to the file. The ejb-jar.xml cannot be
external (see external=false)
The benefit of storing the weblogic-ejb-jar.xml is that your administrator can fine tune certain
configurations by using a deployment plan, instead of having to extract the contents from the jar file
and then repackage it again.
No need to worry about a clustered environment, you can place the jar and the deployment plan
on the server where the admin server is located, when you deploy an application you deploy it to
the cluster and everything is taken care off.

RoboHelp and Eclipse

Hi,
We have been generating XML Help and then with a script changing tag names so that we can incorporate the Help into Eclipse.
However, in RoboHelp 9, RoboHelp adds BOM characters to the html files and Eclipse doesn't seem to handle these characters correctly (even though they are legal).
Is there a way to prevent RH from adding these characters?
I also saw that RH9 supports Eclipse Help - it has the same BOM characters so we couldn't really try it out. Is there any details somewhere on how to integrate the Eclipse Help that RH generates with Eclipse? Wehn we just add the files it doesn't seem to work. Are there instructions anywhere?
Thanks,

Looking up Identical EJB both locally and remotely

prior to posting this request, i have read and
attempted multiple solutions to this problem
suggested in the forums to no avail.
if i have the same EAR, which contains both
an EJB Component and a WAR, deployed to multiple
servers, is it possible to look up an EJB both
locally and remotely?
for instance, on the server performing the lookup,
EJB A is deployed. i successfully look it up
via the following call:
InitialContext context = new InitialContext();
Object ref = context.lookup(name);
return javax.rmi.PortableRemoteObject.narrow("EJBA", EJBAClass.class);
subsequently, i try to lookup the same ejb
on a remote server by performing the following
calls:
Properties environment = new Properties();
environment.put("java.naming.factory.initial", "com.evermind.server.rmi.RMIInitialContextFactory");
environment.put("java.naming.provider.url",
"ormi://remoteserver:23791/application");
environment.put( "java.naming.security.principal", "user");
environment.put( "java.naming.security.credential", "password");
jndiContext = new InitialContext(environment);
Object ref = context.lookup(name);
return javax.rmi.PortableRemoteObject.narrow("EJBA", EJBAClass.class);
however, i either receive an authentican exception, saying "user"
doesnt have access to allication "application", or a null pointer
exception int the RMIInitialContext.
on my local application, i have defined my ejbs in the web.xml
as defined by the spec. the ejb component is marked as remote="false"
in my orion-application.xml as well.
the version of oc4j is 1.0.2.2.1.
any directinon on this would be greatly appreciated.
thanks,
ted rice

as a follow up to my own question, using a application
client, outisde of the web application i can
successfully look up my ejbs locally and remotely.
however, from within the web application, i constantly
receive a ClassCastException.
if no one can tell me how to resolve this, could someone
let me know if they have in fact looked up the
same EJB, both deployed locally and remotely, from the
same web application.
thanks,
ted

Difference between ejb 3.0 and hibernate

Hi, I'm new at ejb 3.0 and I've read a little about Hibernate too, but there's one thing I don't understand. Could you tell me what's the difference between using ejb 3.0 and Hibernate, both of them are for persistence, and What about toplink?

Configuring blazeds, spring, flex and eclipse ide

Hi,
Can you please suggest me in configuring blazeds, spring, flex and eclipse ide. I have tried hard googling, but couldnt get solution for configuring all the four.
thanks in advance

Hi jvk180:
Firstly, you should either need to define the destination in remoting-config.xml or in app-context.xml, but and in both places.
Secondly, the error indicates that it is missing the channel information.
Option 1:
Assuming your bean "helloServiceDestination" uses other Spring beans, then:
1. The right place to declare the destinations is in app-context.xml.
2. In that case, you need to also define the channels that the destination will be exposed over. See documentation for how to do that.
3. In your remote object declaration, you need to pass the channel set that gets used as well.
<mx:ChannelSet id="cs">
<mx:AMFChannel url="http://<yourServerName>:<yourServerPort>:/<yourContextRoot>/messagebroker/amf"/>
</mx:ChannelSet>
<mx:RemoteObject id="ro" destination="helloServiceDestination" channelset="{cs}" result="resultHandler(event)" fault="faultHandler(event)"/>
Option 2:
If you declare your destination, in remoting-config.xml, then you need to compile your swf with services-config.xml. Refer to documentation for how to do that.
Hope that helps.

because JDev has created definitions of the setCoursesDTO function like this:
public void setCoursesDTO(Collection<courseEJBLocalDTO> coursesDTO)
this.coursesDTO = coursesDTO;
and ditto for the setPupilsDTO method, taking a Collection as argument too.
I can fix this code manually, but next step, generating a session Facade with added methods for handling the entity beans isn't exactly any better...
One M:N relation is pretty basic, am I doing something wrong here?

My Question is similar to the question in the cvs and eclipse thread, how can you know on the *.<file_extension>, v the date it was created? thank you very much to those who will reply

Hey wspearman,
Thanks for the question. Genius is still a great feature of iTunes 11, it may be that you simply need to turn it on. To do so, click Store > Turn On Genius
iTunes 11 for Windows: Use Genius Shuffle, Genius playlists, or Genius Mixes

Thanks,
