Jboss Embed for Junit testing

[dhartford]

hey all,
I'm trying to get jboss embed setup for unit testing. I'm running into this problem:

java.lang.RuntimeException: Failed to bootstrap
at org.jboss.embedded.junit.BaseTestCase.bootstrap(BaseTestCase.java:103)
...
Caused by: java.lang.IllegalStateException: Failed to create schema loader: java.lang.ClassCastException org.apache.xerces.dom.DOMXSImplementationSourceImpl cannot be cast to org.w3c.dom.DOMImplementationSource
at org.jboss.xb.binding.Util$2.run(Util.java:517)
at java.security.AccessController.doPrivileged(Native Method)
at org.jboss.xb.binding.Util.getXSImplementation(Util.java:488)
at org.jboss.xb.binding.Util.loadSchema(Util.java:387)
...


If there is a better source of how to use jboss embed for unit testing, that would be nice. I'm using these:

http://www.devx.com/Java/Article/30496/1954

http://docs.codehaus.org/display/MAVENUSER/How+to+use+the+JBoss+Embedded+EJB3+Container+for+Unit+testing

http://wiki.jboss.org/wiki/EmbeddedAndJUnit

Items like the bootstrap-beans.xml is causing grief (don't know what it's supposed to look like), and making sure all the necessary libs are on the classpath, and the right libs (there are like 3 different groups for jboss-embed, different versions).

My maven pom.xml:

jboss
jboss-embedded-all
2.0.0.BETA1
test


trove
trove
2.1.1
test



Any help to get on the right track would be greatly appreciated. I just want to unit test entity, stateless, stateful, mdb in that order of priority with the normal *-ds.xml config files.

oops - target platform is Jboss 4.0.X, hopeful migration to 4.2.x.

EJB3 beans, with JPA 1.0/hibernate implementation (some hibernate Criteria API calls may be made).

For those interested, this weekend I still haven't had much success trying to get Jboss Embed up and running.

However, to coincide with this post:

http://www.jboss.com/index.html?module=bb&op=viewtopic&t=140340

I did get OpenEJB up and running to test my code in a Junit fashion in about an hour.

I don't use Andromda, but found this reference from an Andromda user on how they did it and their own frustrations with Jboss Embed:

I, too, got OpenEJB working for the purposes of unit testing, after two days of tinkering. One thing you should know is that OpenEJB uses OpenJPA as its default persistence provider, so your persistence.xml has to be modified. Also, under OpenEJB, EntityManager#getDelegate() returns a Hibernate EntityManagerImpl instead of a SessionImpl, so you have to call getDelegate twice to get a Hibernate Session. I have not yet been able to make database based authentication or quartz based MDBs working, but they're not necessary for unit testing.
