Remote Client: What library?

[martinganserer]

Hello,

I just want to test a remote swing client on my EJB3 app.
I have a little problem:

When I run my swing app I get following error:

...
Caused by: java.lang.ClassNotFoundException: org.hibernate.collection.PersistentBag
...

Could please somebody tell me the library that I forgot to include?

hibernate3.jar or hibernate-client.jar

Hi,

I added hibernate3.jar but I still get an error! The log tells me that I can "open" the remote interface and that something works on the server.
But when I try to fetch the data the method comes back with following error message:

08:51:38,640 ERROR [ServerThread] failed

Hello,

any ideas about that? Is it maybe a jboss bug?

Thanks!

[delkant]

can you show us some code?

how do you make the client call?

[martinganserer]

Hi,

here it is:

java.util.Hashtable env = new java.util.Hashtable();
env.put(InitialContext.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
env.put(InitialContext.PROVIDER_URL, "jnp://mi01:1099");
env.put(InitialContext.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");

InitialContext ctx = new InitialContext(env);
System.out.println("Context opened!");

ArticleBSIRem articleManager = (ArticleBSIRem)ctx.lookup(ArticleBSIRem.class.getName());

System.out.println("Business service interface opened!");

Article article = null;

article = articleManager.getArticleById("01023-0000-17-2");

Do you need further fragments?

Thank you in advance!

Hi martin,

i arranged a list of all jar which are needed by a remote client.
Just have a look at my wiki

Feel free to add your remarks.

Hello,

thank you for giving me your link. I added the libraries that were missing, but it didn't work! I still get the same error message! :-(

Hello guys,

I made it!!! :-)

It was the commons-logging.jar that was missing!

Thank you all for your help!
