I found the reason for the non-deployment, and I know hope to get some tips on how to fix it. According to the trailblazer: anonymous wrote : All the EJB 3.0 libraries and server-wide configuration files are located in the [server_installation]/server/default/deploy directory... | * The ejb3.deployer/META-INF/persistence.properties file configures the default database for all entity beans and EntityManager in this server. The default is the server's embedded HSQLDB database. | * The ejb3-clustered-sfsbcache-service.xml file contains the MBean configuration for the JBoss Cache service that replicates stateful session beans in a cluster. | * The ejb3-entity-cache-service.xml file contains the MBean configuration for the JBoss Cache service that caches and replicates entity bean objects in a cluster. | When you run the 'all' configuration on the installer, this is not a part of the deployment. I get the ejb3.deployer if I run the ejb configuration on top of the all configuration, but then there is error logging of components allready beeing deployed... I do not need the cluster service and the caching is not necessary, but could be an asset. How do get the all configuration working with ejb3 but with the all configuration?
