Doing BMP with EJB3. JNDI problems?

[jgf1]

Hi again.
Stuck on what I think is an ideosyncrasy in the way JBoss implements JNDI lookups. I was wondering if someone could shed some light?
Following along with Beginning Java EE 5 book again...
I have an application with following directory structure:

BMP
 +beans
 1 StockList.java
 2 StockListBean.java
 +beans_2x
 3 Stock.java
 4 StockBean.java
 5 StockHome.java
 +client
 6 StockClient.java
 +META-INF
 7 Application.xml
 8 Ejb-jar.xml
 9 Jboss.xml
10 StockList2xBmp.jar (contains 8,9, classes for 3,4,5)
11 StockListBmpApp.ear (contains 7 & 10)
12 StockListApp.ejb3 (contains 1 & 2)

11 Gets deployed first, followed by 12.
6 is run with following command:
java -Djava.naming.factory.initial=org.jnp.interfaces.NamingContextFactory -Djava.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces -Djava.naming.provider.url=localhost client.StockClient

I have already had to modify the source of StockClient to conform
to the JBoss way in the getStockList method.

1) I am really surprised JBoss doesn't use the method that is commented out because the current method could lead to class name conflicts if you don't use package prefix...

 private StockList getStockList() {
 StockList stockList = null;
 try {
 // Get a naming context
 InitialContext ctx = new InitialContext();

 // Get a StockList object
 stockList
 = (StockList) ctx.lookup("StockListBean/remote");
 // = (StockList) ctx.lookup(StockList.class.getName());
 } catch(Exception e) {
 e.printStackTrace();
 }
 return stockList;

I think the error is in here somewhere:

private StockHome getStockHome()
 throws NamingException {
 // Get the initial context
 InitialContext initial = new InitialContext();

 // Get the object reference
 Object objref = initial.lookup("beans_2x.Stock");
 StockHome home = (StockHome)
 PortableRemoteObject.narrow(objref, StockHome.class);
 return home;
 }

But I am not sure what to do because I am not sure out JBoss is interpretting
ejb-jar.xml in the node

<entity>
 <ejb-name>StockEjb</ejb-name>
 <home>beans_2x.StockHome</home>
 <remote>beans_2x.Stock</remote>
 <ejb-class>beans_2x.StockBean</ejb-class>
 <persistence-type>Bean</persistence-type>
 <prim-key-class>java.lang.String</prim-key-class>
 <reentrant>false</reentrant>
 <resource-ref>
 <res-ref-name>jdbc/StockDB</res-ref-name>
 <res-type>javax.sql.DataSource</res-type>
 <res-auth>Container</res-auth>
 <res-sharing-scope>Shareable</res-sharing-scope>
 </resource-ref>
 <security-identity>
 <use-caller-identity/>
 </security-identity>
 </entity>

Following on from the pattern I used on StockClient...
2) Do I just use Stock/remote?

Should read
"But I am not sure what to do because I am not sure of how JBoss is interpretting ejb-jar.xml in the node."

Alas this didn't work either.
Just saying Stock not bound now instead!

[jgf1]

In case anyone wants to build/run this here are commands to run from BMP folder:
javac -d . beans_2x\*.java
javac -d . beans\*.java
javac -d . client\*.java

jar vcf StockListApp.ejb3 beans/*.class

jar vcf StockList2Bmp.jar META-INF/ejb-jar.xml META-INF/jboss.xml beans_2x/*.class
jar vcf StockListBmpApp.ear META-INF/application.xml StockList2xBmp.jar

Set up database:
http://localhost:8080/jmx-console/

Follow Hypersonic URL

DROP TABLE stock if exists;
cretae table stock
(
tickerSymbol VARCHAR(10),
name VARCHAR(50),
CONSTRAINT pk_stock PRIMARY KEY (tickerSymbol)
);

Have also tried
Object objref = initial.lookup("beans_2x.Stock/remote");

[jgf1]

Is there is a way to view the JBoss JNDI registry, so I can ascertain the syntax I need?

Thanks for feedback.
Looking at that list the only registered references with "Stock" in them were in the
Global JNDI Namespace:

StockListBean (class: org.jnp.interfaces.NamingContext)
 | +- remote (proxy: $Proxy94 implements interface beans.StockList,interface org.jboss.ejb3.JBossProxy)

I'm in the dark here.

Looking at log messages when archives are deployed everything looks fine.
So why don't I have other JNDI references.
Is there a trailblazer for BMP you can point me to?
Cheers. Jeremy

[alrubinger]

Jeremy:

BMP (Bean-Managed Persistence) is an EJB2 construct (noted by the "beans_2x" package in your sample).

So for this you'd have to construct a valid EJB2.0 deployable unit complete with ejb-jar.xml and other descriptors. Been a long while since I went this route.

What exactly are you trying to accomplish, just work through the book? As a practical measure, using an EJB3/JPA EntityManager with transaction-type="RESOURCE_LOCAL" might be more a line with giving you the finer-grained control of BMT within an EJB3 realm.

I've been scouring throughmy code again and noticed application5.xsd should be application_5.xsd according to book.
I've missed an underscore...
But then in the code download they use _1_4.xsd.
What version should I use with JBoss 4.2.2.GA?

[alrubinger]

I'm not familiar with this book, but I'm not sure about it's aims for you. :)

Application 1.4 is for JEE1.4 == EJB2, Application 5 is for JEE5==EJB3.

My aim is to become familar enough with Java EE to hopefully get a job at some point. In the book they show BMP and describe there may be instances when you need to resort to this such as a database that doesn't support JDBC, or legacy database.
I hope I don't need to do this too often, as it seems an awful lot of effort..
But they say EJB3 is still backwardly compatible with EJB2 for the BMP part.
For me the book didn't cover in enough detail the reason for all that XML plumbing and the relationship between all the artifacts.
If you know of a good online reference for this type of stuff, so I can get a better insight, I'd appreciate it.
I'm hoping the typo in the DTD for application was the reason JNDI lookup wasn't working.
I'm going to have to dig a little deeper to understand the relationship between EJBObject, EntityBean and EJBHome base classes/interfaces.

I am particularly interested in understanding the correlation between the ejb-jar.xml entity node and the getStockHome method in StockListBean and how it relates to JBoss.
I'll try redeploing everything with the fixed application.xml and see if it makes more sense...

I am afraid things still aren't working.

Still saying beans_2x.Stock not bound arising from call to getStockHome() in StockListBean...
1) Should JNDI entries have appeared when the original EAR is deployed?
2) Should I change the headers for:
jboss.xml javaee -> j2ee
ejb-jar.xml 3.0 -> 2.1
application.xml v5 -> 1.4
Or do you think this is going to be irrelevant?
