1. Re: Possible JBoss Bug. Please suggest.
newbeeuser Apr 29, 2004 3:39 PM (in response to newbeeuser)I am now very sure that this is a bug in jboss. I tried deploying the application on jboss 2.4.10. It worked fine. I wonder why the guys from jboss are quiet. Just so that interested people can try this out. I am attaching the code too.
Remote interfacepackage com.ws; import javax.ejb.*; import java.rmi.*; public interface HelloRemote extends EJBObject { public abstract String performTransaction(java.lang.String uri) throws RemoteException ; }
Home Interfacepackage com.ws; import javax.ejb.*; import java.rmi.*; public interface HelloHome extends EJBHome { /** Creates a new instance of HelloHome */ public HelloRemote create() throws CreateException, RemoteException ; }
Session Beanpackage com.ws; import javax.ejb.*; import java.rmi.*; public class HelloBean implements SessionBean { public String performTransaction(java.lang.String uri) throws RemoteException { return "Hello World"; } public void ejbCreate() { } public void ejbRemove() { } public void ejbPassivate() { } public void ejbActivate() { } public void setSessionContext(SessionContext sessioncontext) { ctx = sessioncontext; } SessionContext ctx; }

darranl Apr 30, 2004 4:23 AM (in response to newbeeuser)What happens if you replace
<?xml version="1.0"?>
with<?xml version="1.0" encoding="UTF-8"?>
?
That is the main diference that I can see between mine and yours. -

jonlee Apr 30, 2004 5:00 AM (in response to newbeeuser)JBoss 3.2.x is more strict about the XML checking for deployment descriptors than the 2.4.x series. Most likely, the XML parser is getting upset with the lack of encoding attribute. The DOCTYPE might also be wrong and this can also cause problems but your DOCTYPE example looks OK to me.

sesques Apr 30, 2004 5:30 AM (in response to newbeeuser)I use JBoss 3.2.3 and I can say that:
- JBoss don't care about encoding as much as you do not use UNICODE characters.
- I copy and paste your file header (xml processing instruction and DOCTYPE declaration) in my ejb-jar.xml and I have no problem in deployment.
It can be practical to blame JBoss and its team but useless to solve that problem. I suggest you to avoid theses comments if you want we help you.
Back to the problem, your ejb-jar seems OK. Perhaps the ejb-jar you deploy is not the same you post in this forum (already seen).
Also, you can enable more traces:
Add<category name="org.jboss.ejb.plugins"> <priority value="DEBUG" class="org.jboss.logging.XLevel"/> </category>
in the log4j.xml file and look at the server log file.
Keep cool, newbeeuser -

newbeeuser Apr 30, 2004 2:16 PM (in response to newbeeuser)Thanks for all the replies. Just want to say one thing. My intentions were to malign Jboss. I just want to get the problem solved. Which is still the same. My deployment descriptors are exactly what I have posted here.
I am not denying the fact the I could be possibly missing on some initial configuration the software needs. So, any pointers in that direction will be appreciated. -

mikefinn Apr 30, 2004 4:03 PM (in response to newbeeuser)Are we all looking at the same XML?
The one posted at the start of this thread won't even validate against the DTD. Text where it can't be, no , classnames outside of home and remote tags, etc. I don't know how it could have deployed anywhere.
Something like this might work better:
<?xml version="1.0"?>
<!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN"
"http://java.sun.com/dtd/ejb-jar_2_0.dtd">

<ejb-name>HelloBean</ejb-name>
com.ws.HelloHome

newbeeuser Apr 30, 2004 4:14 PM (in response to newbeeuser)Hi,
I think the forum's GUI parses the home and remote interface to display this. If you compare, both our home and remote interfaces appear the same way.

mikefinn Apr 30, 2004 4:19 PM (in response to newbeeuser)Hehehe. Sorry - it looks like nukes is stripping out *some* of the XML - weird - so what I thought was bad XML maybe was OK? Imagine my surprise when my 'good' xml was the same as the 'bad' xml....
Even the jboss-user-mirrored version I got was hammered.
Sorry for the confusion....

jonlee Apr 30, 2004 10:03 PM (in response to newbeeuser)You might try XDoclet to help you generate the deployment descriptors. We know that works and the XML generated is 100% acceptable by JBoss. I'm suspecting that there is perhaps some (hidden) characters the parser does not like or something to that effect.

11. Re: Possible JBoss Bug. Please suggest.
sesques May 1, 2004 3:16 AM (in response to newbeeuser)In fact, it can be usefull you describe your environment.
You says that the application works fine on JBoss 2.4.10.
With the same hello.jar ?
Or do you re-package it ?
If any "bad character" was in the file, I don't think that the deployment was OK on any version of JBoss. But why not ?
Try activate more traces like I tell you before. Perhaps we got more infos.

newbeeuser May 1, 2004 8:56 PM (in response to newbeeuser)Hi,
Thanks for the pointers and the replies. Yes, the application gets deployed successfully on the 2.4.10. . I drop the same file in the jboss3.2.3. it gives deployment errors.
As far the jboss installation goes. I downloaded the jboss application and i didnt do any configuration on it.
given is the structure of the jar file
com
META-INF
com package contains the java files and META-INF contains the ejb-jar.xml
I am using thejar cvf hello.jar com META-INF
command to create the jar file.
I there any way I can upload the file or it will be great if you guys can email me the sample of the jar file that works fine( a simple hello world jar).
Thanks

Hi,
I am using jboss 3.2.3. I am trying to deploy a simple ejb on it however it gives me the deployment errors. The same bean however deploys successfully on the jboss version 2.4.4.
Given below is the deployment descriptor of the bean.

Looking more precisely at your descriptor and your code (because I want to help you), someting surprises me:
Your says that its a simple EJB and this EJB is a stateless session bean. What is this reference to an entity bean with the same name ?
without an ejb-link.
How is your jboss.xml ?
Why this reference ? -
14. Re: Possible JBoss Bug. Please suggest.
newbeeuser May 3, 2004 11:15 AM (in response to newbeeuser)My jboss reference looks like
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE jboss PUBLIC "-//JBoss//DTD JBOSS 3.2//EN" "http://www.jboss.org/j2ee/dtd/jboss_3_0.dtd"> <jboss> <secure>false</secure> <enterprise-beans> <session> <ejb-name>HelloBean</ejb-name> <jndi-name>HelloBean</jndi-name> <ejb-ref> <ejb-ref-name>HelloBean</ejb-ref-name> <jndi-name>HelloBean</jndi-name> </ejb-ref> </session> </enterprise-beans> </jboss>
The exceptions are being thrown around the DOCTYPE element. So, I am assuming that there is some thing wrong around that tag only.
