EJB 3.0, JBoss 4.2, JPA, JNDI, and Web Services

[mikemurz]

I'm having trouble getting a very simple web service to work. My WSDL is generated correctly, but when I try to invoke one of my web methods with a SOAP request, I get this response back:

<faultcode>env:Server</faultcode>
<faultstring>Endpoint cannot handle requests in state: UNDEFINED</faultstring>

I am fairly certain that this code is very closely related to the problem:

@PersistenceContext(unitName = "bship")
private EntityManager manager;

Because when I comment that code out, all of the sudden my service will send back valid responses. So I'm assuming that means my problem has something to do with JNDI or JPA.

Here is the entity i'm trying to persist in the web method:
http://devk.it/ec0DhwS7NB

Here is my persistence.xml:
http://devk.it/37vCj4EReq

Here is my ds.xml (which is in my /deploy/ folder):
http://devk.it/f13G5pC7xq

Here is the Service Bean:
http://devk.it/6b0451wccr

And here is my Remote interface:
http://devk.it/14etOF2X0O

When I debug my EJB project, an exception similar to the invalid response comes up:

I've been researching away trying to get my EJB setup working, but things are moving very slow because of this problem. All help is very appreciated!

Thank you,

Mike,

Can you please post the console logs when your application is being deployed?

[mikemurz]

Hey Jaikiran,
Thanks for the quick reply. I sifted through my console and grabbed the part that looks like it's effecting my problem. If you need to see the entire log let me know.

So it says:
Cannot find service endpoint target: jboss.j2ee:name=ServiceBean,service=EJB3,jar=Battleship.jar

Does that mean its not deploying my EJB at all? I was pretty sure that the EJB was being deployed correctly. Like I said before, when I comment out the entity manager the add web method works perfectly.

I'm pretty confused while it's getting that exception in the first place. As you can see in my Bean (http://devk.it/6b0451wccr), I've annotated endpointInterface="org.battleship.ejb.ServiceRemote", which is the correct class name of my Remote interface.

It looks like everything may be because of this guy:

--- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM ---
ObjectName: jboss.jca:name=bshipDs,service=DataSourceBinding
State: NOTYETINSTALLED
Depends On Me:
persistence.units:jar=Battleship.jar,unitName=bship


And I noticed that my DS is listed under "packages waiting for a deployer" with a state of INIT_WAITING_DEPLOYER. Did I deploy my DataSource incorrectly?

All I did was put ds.xml in /deploy/ and add the mysql jdbc drivers to /lib/, are there more steps that I'm missing?

[jaikiran]

C:/Users/MMURRAY/Applications/jboss-4.2.3.GA/server/default/deploy/ds.xml

Rename your ds.xml to *-ds.xml. Example: my-ds.xml.

The datasource filenames are expected to end with the -ds.xml name.

[mikemurz]

Thank you jaikaran! That completely fixed it!

I must have mis-read that part of the process.
