I'm trying to get a Seam 2 app working under OC4J 10.1.3. It's going mostly OK, but I'm getting some exceptions regarding my EntityManagerFactory that I can't seem to figure out. Here are my persistence.xml and components.xml files: | <persistence xmlns="http://java.sun.com/xml/ns/persistence" | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" | xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" | version="1.0"> | <persistence-unit name="em" transaction-type="RESOURCE_LOCAL"> | <provider>org.hibernate.ejb.HibernatePersistence</provider> | <jta-data-source>jdbc/Dev</jta-data-source> | <!-- Snip --> | <exclude-unlisted-classes>true</exclude-unlisted-classes> | <properties> | <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/> | </properties> | </persistence-unit> | </persistence> | and <?xml version="1.0" encoding="UTF-8"?> | <components xmlns="http://jboss.com/products/seam/components" | xmlns:core="http://jboss.com/products/seam/core" | xmlns:persistence="http://jboss.com/products/seam/persistence" | xmlns:security="http://jboss.com/products/seam/security" | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" | xsi:schemaLocation= | "http://jboss.com/products/seam/core http://jboss.com/products/seam/core-2.0.xsd | http://jboss.com/products/seam/persistence http://jboss.com/products/seam/persistence-2.0.xsd | http://jboss.com/products/seam/security http://jboss.com/products/seam/security-2.0.xsd | http://jboss.com/products/seam/components http://jboss.com/products/seam/components-2.0.xsd"> | | <core:init debug="false"/> | | <core:manager conversation-timeout="120000" | concurrent-request-timeout="500" | conversation-id-parameter="cid"/> | | | <persistence:entity-manager-factory name="entityManagerFactory"> | </persistence:entity-manager-factory> | <persistence:managed-persistence-context name="entityManager" | auto-create="true" | entity-manager-factory="#{entityManagerFactory}" /> | </components> The exception I get varies, but currently I'm getting "org.hibernate.HibernateException: Hibernate Dialect must be explicitly set" but it looks to me like it is being set. What am I missing? Thanks! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4064134#...
