SEAM 1.2.1.GA JBOSS 4.0.5.GA Trying to exec a DAO method in a Seam-gen'd Seam app using JSF (MyFaces xhtml), SFSB, DAO, and Entity bean. getting following stack trace when I click the commandLink on JSF to exec the action method on the SFSB: Caused by: org.hibernate.HibernateException: Hibernate Dialect must be explicitly set | at org.hibernate.dialect.DialectFactory.determineDialect(DialectFactory.java:57) | at org.hibernate.dialect.DialectFactory.buildDialect(DialectFactory.java:39) | at org.hibernate.cfg.SettingsFactory.determineDialect(SettingsFactory.java:409) | at org.hibernate.cfg.SettingsFactory.buildSettings(SettingsFactory.java:119) | at org.hibernate.cfg.Configuration.buildSettings(Configuration.java:1933) | at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1216) | at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:691) I added the line "hibernate.dialect" line to the persistence.xml below and still getting the same exception after restarting the server and deploying app. I viewed the persistence.xml file in the JAR's meta-inf folder and it matches the one below. Why is it not reading/picking up the new version??? thx. <?xml version="1.0" encoding="UTF-8"?> | <!-- Persistence deployment descriptor for dev profile --> | <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="SHIMS"> | <provider>org.hibernate.ejb.HibernatePersistence</provider> | <jta-data-source>java:/SHIMSDatasource</jta-data-source> | | <properties> | <!-- commented hibernate auto validate due to errors upon deployment (validates the db structure at start-up) --> | <!-- <property name="hibernate.hbm2ddl.auto" value="validate"/> --> | <!-- AS 09-24-07 - added hibernate.dialect property due to error during runtime stating "Hibernate Dialect must be explicitly set" --> | <property name="hibernate.dialect" value="org.hibernate.dialect.SQLServerDialect"/> | <property name="hibernate.cache.use_query_cache" value="true"/> | <property name="hibernate.show_sql" value="true"/> | <property name="jboss.entity.manager.factory.jndi.name" value="java:/SHIMSEntityManagerFactory"/> | <property name="hibernate.default_catalog" value="boSHIMS"/> | <property name="hibernate.default_schema" value=""/> | </properties> | | </persistence-unit> | | </persistence> SHIMSDatasource.xml: <?xml version="1.0" encoding="UTF-8"?> | <datasources> | | <local-tx-datasource> | <jndi-name>SHIMSDatasource</jndi-name> | <connection-url>jdbc:sqlserver://CORG0DV01:1433;databaseName=boSHIMS</connection-url> | <driver-class>com.microsoft.sqlserver.jdbc.SQLServerDriver</driver-class> | <user-name>_AppUser_JavaTestAcct</user-name> | <password>JavaTestAcct</password> | <!-- | <exception-sorter-class-name> | org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter | </exception-sorter-class-name> | <metadata> | <type-mapping>mySQL</type-mapping> | </metadata> | --> | </local-tx-datasource> | | </datasources> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4088112#...
