JBOSS Seam 2.1.1GA on JBOSS AS 5.0.1GA: Table is not mapped

Thu, 07 May 2009 18:37:46 GMT

I created sample JBOSS Seam project in Eclipse and decided to generate entity code from existing database. It worked fine, but when I try to run it, it shows me that Hibernade is not able to map entity beans to the corresponding tables. The error message is like this:

org.hibernate.hql.ast.QuerySyntaxException: <your table> is not mapped

I spent around three hours trying to read all available information on it, but most of it just useless – it looks like people don’t know whats happening, so they recommend bizarre tricks. Like, for example, having empry seam.settings file in each folder, meh.

Finally, I found the solution in Seam Jira: https://jira.jboss.org/jira/browse/JBSEAM-3821

They rocemmend to to force Hibernate to use Seam’s EntityManager by changing two files:

1. components.xml

<persistence:entity-manager-factory name="bookingDatabase" installed="false"/>
    
    <persistence:managed-persistence-context name="em" auto-create="true"
       entity-manager-factory="#{bookingDatabase}" persistence-unit-jndi-name="java:/bookingEntityManagerFactory"/>

2. persistence.xml

<property name="jboss.entity.manager.factory.jndi.name" value="java:/bookingEntityManagerFactory"/>

Hope that Google will find that page and the proper solution would be much more easily found!
