Hi, I noticed that my app is commiting after each statement. Eg: | tx.begin(); | //some persistent modification | tx.rollback(); | tx.commit(); | The rollback does nothing. | <Context | debug="5" | reloadable="true" crossContext="false"> | <Resource | name="jdbc/myDB" | auth="Container" | type="javax.sql.DataSource" | driverClassName="com.mysql.jdbc.Driver" | defaulAutoCommit="false" | factory="org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory" | url="jdbc:mysql://localhos:3306/mydb?autoReconnect=true&autoCommit=false" | validationQuery="select current_date" | removeAbandoned="true" | removeAbandonedTimeout="30" | useNaming="true" | logAbandoned="true" | maxActive="5" | maxIdle="5" | maxWait="15000" | username="xxxxxx" | password="xxxxx"/> | </Context> | persistence.xml | <?xml version="1.0" encoding="UTF-8"?> | <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="myDatabase" transaction-type="RESOURCE_LOCAL"> | <provider>org.hibernate.ejb.HibernatePersistence</provider> | <jta-data-source>java:comp/env/jdbc/myDB</jta-data-source> | <properties> | | <property name="hibernate.hbm2ddl.auto" value="update"/> | <property name="hibernate.show_sql" value="true"/> | <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/> | <property name="hibernate.connection.autocommit" value="false"/> | <!-- <property name="hibernate.datasource" value="java:comp/env/jdbc/myDB"/> --> | <property name="hibernate.cache.provider_class" value="org.hibernate.cache.HashtableCacheProvider"/> | <property name="transaction.flush_before_completion" value="true"/> | <property name="transaction.factory_class" value="org.hibernate.transaction.JDBCTransactionFactory"/> | <!-- RESOURCE_LOCAL | <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup"/> | --> | <!-- alternative | <property name="jboss.entity.manager.factory.jndi.name" | value="java:/coollectBookingEntityManagerFactory"/> | --> | </properties> | </persistence-unit> | </persistence> | Any ideas?
