Illegal @PersistenceUnit? Help!

[mcjava1967]

Hi all. I'm a newbie trying to get JBoss to persist data into a MySql db, using an EJB3. You folks were kind enough to help me get JBoss set up to use MySql, which now seems set. I see new tables, like JMS_MESSAGES, in my MySql db. If it matters, I'm using the JBoss 4.2 Eclipse plugin.

Next, though, my EJB is failing to register when JBoss starts up. I'm getting an "Illegal @PersistenceUnit" message. I should say I'm also a newbie at EJB.

Below is the JBoss log. Below that is my EJB3. I'd really appreciate any help you folks could give me (again...). Thanks!

Post the output of the following command:

1) From the command prompt, cd to the deploy folder of JBoss.
2) Run this command:

jar -tf CMPStockListApp.jar

Post the output here. That will show us whether the jar has been packaged correctly. Also, post the contents of persistence.xml file which is packaged in your application.

By the way, you are using Java 6. I would recommend, using Java 5, since JBoss 4.2 is not fully qualified to run with Java 6.

[mcjava1967]

I actually getting an io exception trying to run the jar command. Might this be related to the packaging itself?

In addition to being a newbie at JBoss, I'm also on Vista for the first time. When I navigate using the file system to CMPStockListApp.jar, it shows as a normal FOLDER. I believe this would cause the io exception. I don't see a single FILE called CMPStockListApp.jar, like I was expecting.

Sorry to sound like SUCH a newbie, but could you recommend a next step? I'll continue working on it here, of course...

Thanks again...

When I navigate using the file system to CMPStockListApp.jar, it shows as a normal FOLDER.

Looks like the application is deployed in exploded form (http://wiki.jboss.org/wiki/Wiki.jsp?page=ExplodedDeployment) which is a valid form of deployment in JBoss.

Sorry to sound like SUCH a newbie, but could you recommend a next step?

Try this then:

- From the command prompt cd to C:/jboss-4.2.2.GA/server/default/deploy/CMPStockListApp.jar (remember the application is a exploded archive, so you will be able to 'cd' to this).
- Run the following command:

dir /b /s

Post the output here.

Hey! That I can do! Here it is:

[mcjava1967]

I couldn't find a persistence.xml file anywhere in my JBoss folders... I did find a persistence.properties. Would that help?

[jaikiran]

You will have to place a persistence.xml file under META-INF folder with the relevant entries in that xml. Go through this http://docs.jboss.org/ejb3/app-server/reference/build/reference/en/html_single/index.html for an introduction about EJB3.

Specifically, look at this http://docs.jboss.org/ejb3/app-server/reference/build/reference/en/html_single/index.html#entityconfig for entity configuration files.

[mcjava1967]

Will do. Trying to work on this tonight. Will post results. Thanks.

[mcjava1967]

OK. I'm getting close!

Within Eclipse, I selected the "JPA facet", which then generated the persistence.xml.

My next problem brings me to precisely the main point I've been trying to learn about--CMP! My example "Stock" class contains these annotions:

@Entity
@Table(schema="BrianDb")

The Eclipse editor is now showing this error message on the @Table line:

"Table 'Stock' cannot be resolved."

Unlike the dozens of previous errors solved to get to this point, this error makes me happy! I'm right at the crux of container-managed persistence now, right?

BrianDb is my MySql db, and the error message is correct: there is no table named "Stock" in it yet.

So next, I'm supposed to do some simple configuration, and that table will be magically created for me, right?

If you can tell me how to do that, I will send you a free six pack, and a big bowl of nacho Doritos.

Thanks!

I've found that if I manually create a table called "Stock", using the MySql Administrator, this error message goes away. So I assume my Eclipse project is correctly viewing my database. I just don't know how to have the tables created automatically on the basis of my annotations and configurations...

I changed persistence.properties, and that created the tables. Now my editor is happy. Last task: get the thing to actually run!

Thanks very, very much for your help. I was pretty lost without you.
