My gateStyle bean and my gate bean is annotation with @(protected) fields correctly. My
components.xml is I believe correct:
| <?xml version="1.0" encoding="UTF-8 (See http://UTF-8.ora-code.com)"?>
| <components xmlns="http://jboss.com/products/seam/components"
| xmlns:core="http://jboss.com/products/seam/core"

"java:/amazinggatesEntityManagerFactory"/>
| <component name="org.jboss.seam.ui.EntityConverter">
| <property name="entityManager">#{em}</property>
| </component>
| </components>
|
Here is my persistence.xml for safe measure:
| <?xml version="1.0" encoding="UTF-8 (See http://UTF-8.ora-code.com)"?>
| <persistence>
| <persistence-unit name="amazinggates">
| <jta-data-source>java:/amazinggatesDS</jta-data-source>
| <properties>
| <property name="hibernate.dialect" value="org.hibernate.dialect
.MySQLDialect"/>
| <property name="hibernate.hbm2ddl.auto" value="update"/>
| <property name="jboss.entity.manager.factory.jndi.name" value=
"java:/amazinggatesEntityManagerFactory"/>
| </properties>
| </persistence-unit>
| </persistence>
|
