I think I just found the reason for the "transaction not enabled". I had removed the "java:" part from the datasource as described in the https://community.jboss.org/thread/204068 thread. Inserting "java:" in front of the datasources at least let me access the repository through the modeshape-rest service without the encountering the "transaction not enabled" exception. Instead I now get tons of exceptions and warnings in the console about transaction problems so there is still something  wrong with the config.

Some parts of the standalone.xml:

The driver

Yes I did see that thread and the https://community.jboss.org/thread/204068 thread and that was the reason

I didn't include the "java:" part in my initial config. But I seem to get further by actually specifying

the "java:" part in the datasource attribute. Might this be something that has changed in the latest releases

(I'm using 3.1.2.Final)?

/Pontus

After reading this thread https://community.jboss.org/thread/206688 i decided to skip the JBoss 7.1.1 & Modeshape 3.1.2 combination. I also noticed that theres a 7.1.3.Final tag availbale at https://github.com/jbossas/jboss-as/tags and that version at least seem to use Infinispan 5.1.7.Final.

I did try to use 3.1.2 in 7.1.3 and it almost to works. Modeshape starts with no exceptions and it is possible to access the file based repositories. Accessing a repository using an Infinispan cache with a JDBC loader will still fail but in this case it fails since it hasn't been able to fully initialize the repository (after 10 minutes).

If anyone else want to try the JBoss 7.1.3.Final + Modeshape 3.1.2.Final combination then you will probably encounter a ClassNotFoundException where a Hibernate annotation class is missing. The reason for this is that the annotation classes has been moved to its own module in 7.1.3. The fix for this seem to be to replace the dependency

{code:xml}<module name="org.hibernate"/>{code}

in /modules/org/hibernate/search-engine/4.1/module.xml with

{code:xml}<module name="org.hibernate.commons-annotations"/>{code}

Also notice that the standalone-modeshape.xml included in the modeshape-3.1.2.Final-jbossas-71-dist.zip probably can't be used directly since there's other changes in the 7.1.3 standalone.xml. The fix for this is to add the Modeshape stuff to your own standalone.xml based on the one included in 7.1.3.
