Well, I tried running some Seam examples. I proceeded like suggested in the 
getting started section 
(http://labs.jboss.com/portal/jbossseam/gettingstarted/index.html). But it 
didn't work out that easy, cause I'm running from one error into the other.

After installing JBoss 4.0.4 AS via the JEMS installer 
(jems-installer-1.2.0-BETA.jar) with EJB3 profile I deployed some of the Seam 
1.0.1 (fetched via CVS) examples (namely booking and blog - each one 
individually). But after starting the AS I get an exception and deployment 
fails:

java.lang.NoClassDefFoundError: Lorg/jboss/ejb3/embedded/EJB3StandaloneDeployer;

So I put jboss-ejb3-all.jar (8.019 KBytes for comparison) from EJB3.0 RC8 into 
$JBOSS_HOME/server/default/lib (as recommended here by Gavin: 
http://www.jboss.com/index.html?module=bb&op=viewtopic&t=85604). Well, now 
there's a new very nice exception:

java.lang.NoSuchMethodError: 
org.jboss.resource.adapter.jdbc.local.LocalManagedConnectionFactory.getValidateOnMatch()Z

This one occurs 18 times in the logfile. And I found no solution for that, so I 
decided to ignore it for now.

However, another Exception told me there's no embedded-jboss-beans.xml. So I 
copied it from the Seam directory embedded-ejb/conf to 
$JBOSS_HOME/server/default/conf. After restarting the AS there's a new 
Exception:

java.lang.RuntimeException: org.jboss.xb.binding.JBossXBException: Failed to 
parse source file: file:/C:/Programme/jboss-4.0.4.GA/server/default/conf/[EMAIL 
PROTECTED],45
  | ...
  | Caused by java.lang.NullPointerException
  | at 
org.jboss.kernel.plugins.deployment.xml.BeanSchemaBinding.configureValueBindings(BeanSchemaBinding.java:1158)

Well, the embedded-jboss-beans.xml looks like this (where *** shows 5,45, the 
position where the error occured)

<?xml version="1.0" encoding="UTF-8"?>  
  |    
  |   <deployment xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";  
  |               xsi:schemaLocation="urn:jboss:bean-deployer 
bean-deployer_1_0.xsd"  
  |               xmlns="urn:jboss:bean-deployer">*** 
  |      <bean name="Naming" class="org.jnp.server.SingletonNamingServer"/>  
  | 
  | ...

And this is where I'm stuck.

Well, maybe I overlooked something in my procedure, and I must confess I'm not 
a JBoss AS expert... but I think this shouldn't be necessary just to get some 
Seam examples to work.

Maybe someone could tell me what's wrong.
