Hi !!

My configuration is :
Eclipse 3.1.2
jboss-4.0.4.GA
JDK 1.5

I'm experencing MyEclipse plugin for a school project. I followed the first-ejb3-ant tutorial and I dident succeded to deploy the application. this is what I get in JBOOS while running it:

Code:

17:17:46,107 ERROR [URLDeploymentScanner] Incomplete Deployment listing: --- MBeans waiting for other MBeans --- ObjectName: persistence.units:jar=FirstEJB3Tutorial Ant.jar,unitName=FirstEjb3Tu torial   State: FAILED   Reason: org.hibernate.HibernateException: Hibernate Dialect must be explicitly  set   I Depend On:     jboss.jca:service=ManagedConnectionFactory,name=ejb3ExampleDS   Depends On Me:     jboss.j2ee:jar=FirstEJB3Tutorial Ant.jar,name=BookTestBean,service=EJB3 ObjectName: jboss.j2ee:jar=FirstEJB3Tutorial Ant.jar,name=BookTestBean,service=E JB3   State: NOTYETINSTALLED   I Depend On:     persistence.units:jar=FirstEJB3Tutorial Ant.jar,unitName=FirstEjb3Tutorial --- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM --- ObjectName: persistence.units:jar=FirstEJB3Tutorial Ant.jar,unitName=FirstEjb3Tu torial   State: FAILED   Reason: org.hibernate.HibernateException: Hibernate Dialect must be explicitly  set   I Depend On:     jboss.jca:service=ManagedConnectionFactory,name=ejb3ExampleDS   Depends On Me:     jboss.j2ee:jar=FirstEJB3Tutorial Ant.jar,name=BookTestBean,service=EJB3

Anyway I tried to lunch the application but it didnt work (naturally)

Code:

Please help because I must make a demo this monday to my schoolmates

Thanks in advance

Hi again I resolved my problem I forgot to put the driver cause I reinstalled Jboss :oops:

Thanks In Advance

Not sure but you may be missing something on your classpath.

I did not get the example working with 4.0.4 GA.

I had to add the project name in front of the jndi name:

public static final String RemoteJNDIName = "TestEJB3App/" + BookTestBean.class.getSimpleName() + "/remote";

public static final String LocalJNDIName = "TestEJB3App/" + BookTestBean.class.getSimpleName() + "/local";


Greetings,

Hi, I am an EJB3 newbie. I'm trying to deploy laliluna EJB3 tutorial but I came across problems.

Here are my settings
__
MS Win Xp pro SP2
Java 1.5.0_07
Eclipse 3.2 with JBoss Eclipse IDE 1.6.0.GA plugin installed
JBoss 4.0.4 GA installed and running
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>
<exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>
<!-- should only be used on drivers after 3.22.1 with "ping" support
<valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLValidConnectionChecker</valid-connection-checker-class-name>
-->
<!-- sql to call when connection is created
<new-connection-sql>some arbitrary sql</new-connection-sql>
-->
<!-- sql to call on an existing pooled connection when it is obtained from pool - MySQLValidConnectionChecker is preferred for newer drivers
<check-valid-connection-sql>some arbitrary sql</check-valid-connection-sql>
-->

<!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) -->
<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

---------------------------------------------------------------------------------------

I can't go further in the exercise, is there anyone can help me do succeed?

thanks

G.

idtech,
Be sure to email Sebastian over at LaLiLuna and please post your findings here if you get the issue resolved (off hand I don't know what is wrong, I'm sorry)

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

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"?> <!-- $Id: mysql-ds.xml 41016 2006-02-07 14:23:00Z acoliver $ --> <!--  Datasource config for MySQL using 3.0.9 available from: http://www.mysql.com/downloads/api-jdbc-stable.html --> <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>     <password></password>     <!-- the minimum size of the connection pool -->     <min-pool-size>1</min-pool-size>     <!-- The maximum connections in a pool/sub-pool -->      <max-pool-size>4</max-pool-size>           <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>     <!-- should only be used on drivers after 3.22.1 with "ping" support     <valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLValidConnectionChecker</valid-connection-checker-class-name>     -->     <!-- sql to call when connection is created     <new-connection-sql>some arbitrary sql</new-connection-sql>       -->     <!-- sql to call on an existing pooled connection when it is obtained from pool - MySQLValidConnectionChecker is preferred for newer drivers     <check-valid-connection-sql>some arbitrary sql</check-valid-connection-sql>       -->     <!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) -->     <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...

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.

I am getting the following error. Can someone please tell me which jar file has this NamingContextFactory class?
Thanks

hi all

I am on the full subscription of MyEclipse IDe with the latest one is 6

so I rely more on the help search for tutorial of project called SampleEJBProject . The one now is ejb3. I followed all the steps .but only difference that I use Jboss.so Please read the error I get. in numbers.

1 - last four lines of deploying

4 - I use MyEclipse 6, Jboss 4.2 windos 2000

I have error too in Mr Sabastian's tutorial but he uses entity which I like to get a seesoin only to work first also I use mysql which needs different annotaions that I do not know where to palce too. moreover I like Myeclipse help tutorials more

please guide to the problem of if any good guy would email me the working code zipped or I send hih/her mine to very slightly amendment or JBoss slight setting.

my email alhakim55@yahoo.com or PM.

kinds to all

I

I am trying to deploy this sample application to jboss ejb container.
jmx console is not showing BookTestBean deployed, but I can see datasource ejb3ExampleDS.

Also I am not getting any error message on system console and jboss log.

log message:
2008-02-26 16:54:39,703 DEBUG [org.jboss.ejb.EjbModule] Started jboss.j2ee:service=EjbModule,module=FirstEJB3Tutorial.jar

I am totally new to ejbs, I have never tried provious version of ejb.
am I missing anything?
any pointer will be greatly appreciated...

Thanks

Sachin.

hello,
thanks for your post. can you post a EJB 3 tutorial with glassfish ???
