ejb-transaction - convert to 2.1 fails

[x490812]

I have a seam project built with maven for seam 2.0.2.sp1. works fine. I do the following to convert over to seam 2.1.0.GA

1) change version of jboss-seam to be 2.1.0.SP1

2) change all schema locations in components.xml from 2.0.xsd to 2.1.xsd

3) change pages.xml doctype from pages-2.0.dtd to 2.1.dtd

The result is that at jboss 4.2.0.GA startup I get the below error. Is there some other conversion step I am missing?

Hello!

I have the same problem. Does anyone have a solution for that problem?

I have also tried to update JBoss AS from 4.2.2.GA to 4.2.3.GA but nothing changed.

My error was not EjbTransaction but Identity because it came before EjbTransaction in the components.xml. I also tried to change the order. Then I got the same exception but with EjbTransaction: name and class are null.

Generally spoken: is the order in components.xml important?

Could it be that this exception is thrown because components.xml is initialized before all components tagged with @Name are loaded??? This is only my opinion, perhaps it is absolutly wrong... :)

Let's have a look in the source code, perhaps this will help...

Nice greetings.

I got this once because I had jboss-seam.jar in two places...once in WEB-INF/lib, and once in the top level of the ear.  The @Namespace annotation class was found in the WEB-INF/lib one, and cached by the jdk annotations support,  and therefore the transaction pkg-info.class didn't look like it had a @Namespace annotation to the seam scanning code, so the namespace descriptor wasn't built correctly.

Hello again!

Thank you very, very much. I had this issue with duplicated JAR files that often...
Indeed, jboss.seam.2.1.0.SP1.jar was in my EAR file AND in lib folder of my WAR file. So I added exclusions for this dependency on the following dependencies of the pom-File in my WAR-Project:
- my own EJB project (has also seam as dependency)
- jboss-seam-ui
- jboss-seam-mail
- jboss-seam-pdf

But then I got another error, because a certain class (sorry cant remember since yesterday, bad brain...) was not found during JBoss startup. I also had to add org.jboss.el.jboss-el.2.0.2.CR1 to my EAR file (I have JBoss 4.2.2.GA). I dont know exactly but I think this dependency exists  already in JBoss 4.2.3.GA.

I hope this post was helpful also for others which are going to update to the new version.

Nice greetings.

Hey, i have similar type of problem, but it is because of Error loading element HotDeployFilter with component name null and component class null

I am using seam 2.1.0SP1 and jboss-4.2.3.GA

jboss-seam.jar is only in ear

stacktrace is

Is there anything wrong with my component.xml ??
