ejb client jndi problem
I deploy ejb jar in geronimo2.0.1, this is a ejb2 test
http://www.nabble.com/file/p12813817/simple-ejb2-1.0.jar simple-ejb2-1.0.jar
, and this is a ejb3 test
http://www.nabble.com/file/p12813817/simple-ejb3-1.0.jar simple-ejb3-1.0.jar
.
Both of them deploy no error.
My client is a standalone application. Test code:
public class ClientTest {
public static EchoRemote getEchoService(String url,
String contextFactory) throws Exception {
Context context = getInitialContext(contextFactory, url);
Object obj = context.lookup("Echo");
return (EchoRemote) obj;
}
public static CounterRemote getCounterService(String url,
String contextFactory) throws Exception {
Context context = getInitialContext(contextFactory, url);
Object obj = context.lookup("SuperCounterBusinessRemote");
return (CounterRemote) obj;
}
private static Context getInitialContext(String initContextFactory,
String url) throws Exception {
Properties properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY, initContextFactory);
properties.put(Context.PROVIDER_URL, url);
return new InitialContext(properties);
}
public static void main(String[] args) throws Exception{
String url = "ejbd://localhost:4201";
String factory = "org.openejb.client.RemoteInitialContextFactory";
EchoRemote echo = getEchoService(url, factory);
assert("cba".equals(echo.echo("abc")));
// CounterRemote counter = getCounterService(url, factory);
// assert(counter.reset()==0);
// assert(counter.increment()==1);
// assert(counter.increment()==2);
// assert(counter.reset()==0);
}
}
exception:
Exception in thread "main" javax.naming.NameNotFoundException: /Echo does
not exist in the system. Check that the app was successfully deployed.

What's the right jndi name?
I see some other messages talk about ejb jndi, but still can't resolve my
problem.
I deploy ejb2 test in geronimo 1.x, client lookup no problem.

Hi,
David has put a sample out here that does pretty much what you want to do -
http://people.apache.org/~dblevins/tmp/examples/SimpleApp/src/test/java/org/apache/openejb/examples/counter/EchoImplTest.java
You might want to modify your code a bit and try again. I was able to
run the EchoImplTest on g 2.0.1.

Re: ejb client jndi problem
Posted by wanyna <wa...@hotmail.com>.
By using jndi name like
"simple-ejb3/Echo/org.apache.openejb.examples.counter.ejb3.EchoRemote",
client lookup success both ejb2 and ejb3 test.
I feel what's talk about in http://openejb.apache.org/jndi-names.html is not
easy to understand.
And the default jndi name mentioned in this page not match my test.
How can I use same jndi name of a ejb in a web app or a standalone app?

Re: AW: ejb client jndi problem
Posted by wanyna <wa...@hotmail.com>.
Thanks.
In my test simple-ejb2-1.0.jar wrapped in an ear, test passed with jndi name
"simple-ejb2-1.0.jar/Echo/org.apache.openejb.examples.counter.ejb2.Echo".
I am used to configure jndi name in openejb-jar.xml or other j2ee server's
application description file. Whaterver ejb wrapped in, and what type client
is, the same is jndi name. I feel it's simple and easy to use.
I'm glad to hear you will make this consistent in next version.
But can you tell me why openejb3's jndi name was designed more complex now?

(I could be wrong in my answer). In an ear, the first component of
the jndi name is the ejb jar name. So if your ejb jar is called
simple-ejb3.jar, the jndi name would be
simple-ejb3.jar/Echo/org.apache.openejb.examples.counter.ejb3.EchoRemote
For a standalone ejb jar, the first component is the artifactId
specified in the geronimo plan for the app. If you don't supply a
plan or don't supply a moduleId for the plan (it might be required,
I'm not sure), the default is the name of the jar with the extension
removed, in this case simple.ejb3.
So, you can get the same name in and out of the ear by setting the
artifactId to simple-ejb3.jar in the geronimo plan.
We're considering if and how to make this more consistent in 2.0.2
and/or 2.1

Thanks.
By using jndi name like
"simple-ejb3/Echo/org.apache.openejb.examples.counter.ejb3.EchoRemote",
client lookup success both ejb2 and ejb3 test.
But when I wrap this ejb jar in an ear, my test application failed again.
What's correct jndi name in this case?

AW: ejb client jndi problem
Posted by "Ueberbach, Michael" <mi...@dbh.de>.
Hi,
I don't know exactly your situation, please check the following conditions:
- you deployed a EJB 3.0 application in an xxx-ejb.jar
- you configured an openejb-jar.xml deployment plan where you set an artifactId for your app, let's say "MyApp"
- you have a session bean you want connect to, let's say "MySessionBean"
- you have build a remote interface for your session bean (EJB 3.0 means a simple interface), let's say "MySessionRemote"
then the following is the right jndi name to get a connection to your bean
"MyApp/MySessionBean/my.package.MySessionRemote"
You have to use the fully qualified class name for the Interface!
Regards
Michael

Betreff: ejb client jndi problem
I deploy ejb jar in geronimo2.0.1, this is a ejb2 test http://www.nabble.com/file/p12813817/simple-ejb2-1.0.jar simple-ejb2-1.0.jar , and this is a ejb3 test http://www.nabble.com/file/p12813817/simple-ejb3-1.0.jar simple-ejb3-1.0.jar .
Both of them deploy no error.
My client is a standalone application. Test code:
public class ClientTest {
public static EchoRemote getEchoService(String url,
String contextFactory) throws Exception {
Context context = getInitialContext(contextFactory, url);
Object obj = context.lookup("Echo");
return (EchoRemote) obj;
}
public static CounterRemote getCounterService(String url,
String contextFactory) throws Exception {
Context context = getInitialContext(contextFactory, url);
Object obj = context.lookup("SuperCounterBusinessRemote");
return (CounterRemote) obj;
}
private static Context getInitialContext(String initContextFactory,
String url) throws Exception {
Properties properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY, initContextFactory);
properties.put(Context.PROVIDER_URL, url);
return new InitialContext(properties);
}
public static void main(String[] args) throws Exception{
String url = "ejbd://localhost:4201";
String factory = "org.openejb.client.RemoteInitialContextFactory";
EchoRemote echo = getEchoService(url, factory);
assert("cba".equals(echo.echo("abc")));
// CounterRemote counter = getCounterService(url, factory);
// assert(counter.reset()==0);
// assert(counter.increment()==1);
// assert(counter.increment()==2);
// assert(counter.reset()==0);
}
}
exception:
Exception in thread "main" javax.naming.NameNotFoundException: /Echo does not exist in the system. Check that the app was successfully deployed.

at test.ClientTest.getEchoService(ClientTest.java:17)
at test.ClientTest.main(ClientTest.java:40)
What's the right jndi name?
I see some other messages talk about ejb jndi, but still can't resolve my problem.
I deploy ejb2 test in geronimo 1.x, client lookup no problem.
