seam-gen for me has been buggy so i use this now http://chiralsoftware.com/master-sauce/ Master Sauce for mysql connection in the resources folder in the **ds.xml i have this <?xml version="1.0" encoding="UTF-8"?> | | <!DOCTYPE datasources | PUBLIC "-//JBoss//DTD JBOSS JCA Config 1.5//EN" | "http://www.jboss.org/j2ee/dtd/jboss-ds_1_5.dtd"> | | <datasources> | | <local-tx-datasource> | <jndi-name>sdeskoneDatasource</jndi-name> | <connection-url>jdbc:mysql://localhost:3306/test</connection-url> | <driver-class>com.mysql.jdbc.Driver</driver-class> | <user-name>root</user-name> | <password></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> | | and in META-INF/persistence*.xml i have this <?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="sdeskone"> | <provider>org.hibernate.ejb.HibernatePersistence</provider> | <jta-data-source>java:/sdeskoneDatasource</jta-data-source> | <properties> | <property name="hibernate.hbm2ddl.auto" value="validate"/> | <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:/sdeskoneEntityManagerFactory"/> | </properties> | </persistence-unit> | | </persistence> | seems to do the work but really seam-gen wasted "days/weeks" of my time.
