MyEclipse: EJB 3 Tutorial with JBoss

Post subject: EJB 3 Tutorial with JBoss

Hello,
I have just added an free EJB 3 tutorial to my website. It shows the complete setup with MyEclipse.

The use of entity beans and a stateless beans is explained step by step.
I am going to add a Ant setup, a setup for other application server as soon as possible.

Another tutorial showing Struts and EJB 3 is nearly finished as well.

Best Regards

Sebastian,
This is excellent news, a lot of our users rely on your tutorials to help them learn technologies and tools which is no small feat.

Do you have a direct link to the tutorial? I checked the English Tutorial section and didn't see one from March '06 for EJB in the EJB section, maybe I missed it?

Thanks for the tutorial! I've learned a lot from the LaLiLuna site. One recommendation I'd make is to add the import (import javax.persistence.*;) to the Book class since it says "this is our full source code now". Since I didn't download the source code at first, I was confused by the errors MyEclipse was giving me before adding the import statement.

Also, for MySQL, you can use @GeneratedValue(strategy = GenerationType.AUTO) and remove the @SequenceGenerator annotation - that worked for me.

You can get by with a lot less included libs - I couldn't find some of them, like qdox.jar, but it worked without them.

Thanks again!

Post subject:

Just a little info on which libs are needed... My "EJB3" user lib only has ejb3-persistence.jar and jboss-ejb3x.jar - for Entity and Session beans, this is all I've needed so far. For my "JBoss4-Client" user lib, I've got a screenshot here: http://www.market-assist.com/~osterday/pics/screenshots/ejb3-userlibs.png.

Thanks again for the great work Sebastian! (I hope to donate soon!)

First of all, thank you for a nice tutorial. I am sure I would have not gotten up the learning curve without your insight.

I am working through your EJB3.0 Ant Tutorial. I have been successful in getting this EJB project to deploy properly in JBOSS4.0.3SP1. In one case I had to strip out the EJB 2.1 jars and conf xml file and drop in the EJB3.0 stuff to make the server work. I know it was not part of your tutorial and JBOS gives some clear instructions on what to do. :-)

Here are some things you might want to look at when you update your tutorial.

1. Creating a Java Project vs. an EJB Project. Your instructions call for creating a Java Project, but your Screen shot shows you created an EJB Project.

2. The Book class is missing the import statments for the javax.persistence.* classes.

3. In the session bean add the unitName attribute in the annotation. I changed my around some, just to be different ;-)

Code:

@PersistenceContext(unitName="Ejb3Demo")

I sure these errors are just the difference between the current code today and the code you used back when you originally created the tutorial.

Again, thank you for putting together a nice aritcle. I look forward to finishing it and moving onto others.

Russ

Russ,

Thanks very much for the feedback; you've provided some valuable insights. We'll be sure the authors see it when we update it next.

Post subject: Problem with annotations

Hi,

I have problemes with annotations ...

I have problemes with :

Code:

@Entity
@Table(name="book")
@SequenceGenerator(name = "book_sequence", sequenceName = "book_id_seq")
public class Book implements Serializable {

Error is :

Code:

Entity cannot be resolved to a type

But I haven't with

Code:

@Override
public String toString() {

Why ? strange ...

Can you help me ?

Thanks !!

I can't see my Bean in JNDI View

I have look source but ...

Problems with XDoclet ?

Post subject:

laguiz, check your jboss log file to make sure your deployment was successful - sometimes jboss problems don't show up in the console window and you have to check the log. With ejb3, I'm pretty sure there is no need to run XDoclet.

I work with MySQL.
Wy we can't use GenerationType.SEQUENCE with MySQL (if probleme is MySQL) ?

jboss-EJB-3.0_Embeddable_ALPHA_8-patch2 libraries available
MySQL DBMS 4.1.7
MySQL driver Connector/J 3.1.13 copied in the server/default/lib directory

I have not created "by hand" any tutorial database in the DBMS.

I created an EJB project in Eclipse and followed the FirstEjb3Tutorial notes, downloaded from the laliluna website.

My persistence.xml file is

--
<persistence>
<persistence-unit name="FirstEjb3Tutorial">
<jta-data-source>java:/ejb3ProjectDS</jta-data-source>
<properties>
<property name="hibernate.hbm2ddl.auto" value="create-drop" />
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLInnoDBDialect"/>
</properties>
</persistence-unit>
</persistence>
--

My mysql-ds.xml in the server/default/deploy dir is

--
<datasources>
<local-tx-datasource>
<jndi-name>ejb3ExampleDS</jndi-name>
<connection-url>jdbc:mysql://localhost:3306/ejb3Example</connection-url>
<driver-class>com.mysql.jdbc.Driver</driver-class>
<user-name>omissis</user-name>
<password>omissis</password>

<metadata>
<type-mapping>mySQL</type-mapping>
</metadata>
</local-tx-datasource>
</datasources>

..and the ejb-jar.xml is

---
<?xml version="1.0" encoding="UTF-8"?>
<ejb-jar>
<enterprise-beans>
</enterprise-beans>
</ejb-jar>

When I deploy the tutorial I get the following log from JBOSS

Read carefully the quoted output. It says that a deployer is missing the ejb3ProjectDS datasource. There can be two reasons for that:

1. Youre datasource is named something different. Make sure that your *-ds.xml datasource descriptor file really declares this name.

Code:

<jndi-name>ejb3ProjectDS</jndi-name>

2. The *-ds.xml file is not deployed. Copy the file to the jboss/server/default folder

Don't forget to restart jboss

Post subject: Problem with the persistance unit

Hi, i try to test the tutorial but i have a problem with the persistance unit.
I can't see the jndi name corresponding to my ejb in the web-console.
My persistance.xml file is:

Quote:

<persistence>
<persistence-unit name="FirstEjb3Tutorial">
<jta-data-source>java:/ejb3ProjectDS</jta-data-source>
<properties>
<property name="hibernate.hbm2ddl.auto"
value="create-drop"/>
</properties>
</persistence-unit>
</persistence>

I also have deployed a file mysql-ds.xml which is:

Code:

<?xml version="1.0" encoding="UTF-8"?>




<datasources>
<local-tx-datasource>
<jndi-name>MySqlDS</jndi-name>
<connection-url>jdbc:mysql://localhost:3306/examples</connection-url>
<driver-class>com.mysql.jdbc.Driver</driver-class>
<user-name>root</user-name>

<min-pool-size>1</min-pool-size>

<max-pool-size>4</max-pool-size>

<metadata>
<type-mapping>mySQL</type-mapping>
</metadata>
</local-tx-datasource>
</datasources>

When i start my jboss server i have the following erros:

I tried to edit my persistance.xml but i always have erros.
Do you know where is the problem with my persistance unit ?

Hm.. I have the same error when trying to deploy the example. The persistence.xml file seems to be ok...

jeromy - Jun 09, 2007 - 05:09 AM
Post subject: How to fix the example

The example at http://www.laliluna.de/ejb-3-tutorial-jboss.html does not work if you copy-and-paste the code because the datasource name in persistence.xml is "ejb3ProjectDS" but the datasource name in myFavouriteName-ds.xml is "ejb3ExampleDS".

The mismatch will cause the error:

Code:

--- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM ---
ObjectName: jboss.jca:name=ejb3ProjectDS,service=ManagedConnectionFactory
State: NOTYETINSTALLED

because ejb3ProjectDS is not defined.

To fix it ensure the datasource name in your persistence.xml file matches the jndi name of the datasource in your *-ds.xml file. Use any name you like.

Sorry to hijack EJB3 tutorial but this is the closest I could find to post my question.

I'm try to run setup my EJB2 project from http://www.myeclipseide.com/documentation/quickstarts/firstejb/.

My problem is w/XDoclet. I'm using JBOSS 4.3.2.GA and the message I get from the compiler is this:
