> When you generate Seam project in Seam-gen, it will create build.xml inside your new project. In this build.xml file there is handled "puJndiName" variable, which is then referenced in components.xml. The problem is that this variable is not set properly, because it depends on value of variable "seamBootstrapsPu" and this variable is assigned based on availability of ${jboss.home}/lib/jboss-vfs.jar file, which does not exist in AS7.
> So the problem is this line (69) in build.xml:
> <available file="${jboss.home}/lib/jboss-vfs.jar"/>
> When the entityManager could'nt be found, following exception occurs:
> {noformat}
> Caused by: javax.naming.NameNotFoundException: entityManager -- service jboss.naming.context.java.entityManager
> 	at org.jboss.as.naming.ServiceBasedNamingStore.lookup(ServiceBasedNamingStore.java:97)
> 	at org.jboss.as.naming.NamingContext.lookup(NamingContext.java:178)
> 	at org.jboss.as.naming.InitialContext.lookup(InitialContext.java:119)
> 	at org.jboss.as.naming.NamingContext.lookup(NamingContext.java:214)
> 	at javax.naming.InitialContext.lookup(InitialContext.java:392)
> 	at org.jboss.seam.persistence.ManagedPersistenceContext.getEntityManagerFactoryFromJndiOrValueBinding(ManagedPersistenceContext.java:257)
> {noformat}
