Question

I have a client and server setup to run with JBoss AS 7.1.1 and I have a question about my persistence.xml. Currently it looks like this:

<persistence>
    <persistence-unit name="GrahamsProj">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <jta-data-source>java:jboss/datasources/WorkCenterDS</jta-data-source>
        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
            <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
            <property name="hibernate.connection.driver_class" value="oracle.jdbc.OracleDriver"/>
        </properties>
    </persistence-unit>
</persistence>

I have persistence.xml in the META-INF folder of my server. I must be missing some properties though because I’m getting this error when I try to query the database I’m connected to.

11:35:07,840 ERROR [org.jboss.ejb3.invocation] (EJB default - 1) JBAS014134: 
EJB Invocation failed on component GrahamsProjBean for method public abstract 
void grahamsprojserver.session.interfaces.GrahamsProjBeanRemote.test(): javax.ejb.EJB
Exception: java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: 
Schemas is not mapped [FROM Schemas s]

Is there something I’m missing?

Answer 1

you need to include all your model classes in persistence.xml. example:

<persistence>
    <persistence-unit name="GrahamsProj">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <jta-data-source>java:jboss/datasources/WorkCenterDS</jta-data-source>
        <class>your.class.model.Example</class>
        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
            <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
            <property name="hibernate.connection.driver_class" value="oracle.jdbc.OracleDriver"/>
        </properties>
    </persistence-unit>
</persistence>
