Basic Spring+AMQ+XBean+embededbroker problem
Ok, well I'm officially stumped, but I can't get a basic Spring+AMQ
4.1.1+XBeans with embedded broker test harness to work using the
configuration outlined here:
http://activemq.apache.org/how-do-i-embed-a-broker-inside-a-
connection.html
I get a ClassNotFoundException (see [1]). Now, _obviously_ I'm
missing something in the class path, but I cannot work out what is
missing. I looked at the AMQ pom.xml to see if something jumped out,
but I can't work it out. I'm familiar with Maven and Spring
recently getting on board the bandwagon, but definitely no expert, so
I'm sure this is related to that.
My test harness has these dependencies in it's pom:
<dependencies>
<dependency>
<groupId>org.apache.activemq</groupId>
<artifactId>activemq-core</artifactId>
<version>4.1.1</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring</artifactId>
<version>2.0.5</version>
</dependency>
<dependency>
<groupId>org.apache.xbean</groupId>
<artifactId>xbean-spring-v2</artifactId>
<version>2.8</version>
</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.2</version>
<scope>test</scope>
</dependency>
To maximize my chances of help, I've even created a simple mavenized
test project to demonstrate:
http://people.apache.org/~psmith/activemqspringtestbed.tar.gz
What am I missing? I'm fully prepared to be slapped in the face with
the obvious.

You're welcome :)
We should maybe create a maven artifact for a java project using
ActiveMQ with the pom set just right etc...

ahhhhhhhh. I mean I spent _ages_ searching mvnrepository.com.
There's unfortunately about 400 million different options with search
terms 'xbean' and 'spring', and I have to swear I thought I tried
that combo (maybe not 2.8 version).
Thanks muchly for your help.

Try adding this dependency...
<dependency>
<groupId>org.apache.xbean</groupId>
<artifactId>xbean-spring</artifactId>
<version>2.8</version>
</dependency>
As xbean-spring was built to support both spring 1.x and 2.x so its in
2 modules, the core and the spring 2 specific stuff.
>From 3.x onwards, xbean-spring just depends on spring 2 so AFAIK its one module
