  • Configure ehCache with Roo

    Hello:

    I am confused on how to configure the persistence.xml file for Read-only use of ehCache:

    I have modified the persistence.xml file as follows.:

    <?xml version="1.0" encoding="UTF-8" standalone="no"?>
    <persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
    <persistence-unit name="persistenceUnit" transaction-type="RESOURCE_LOCAL">
    <!--
    <provider>org.hibernate.ejb.HibernatePersistence </provider>
    -->
    <properties>
    <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect"/>
    <!-- value="create" to build a new database on each run; value="update" to modify an existing database; value="create-drop" means the same as "create" but also drops tables when Hibernate closes; value="validate" makes no changes to the database -->
    <property name="hibernate.hbm2ddl.auto" value="validate"/>
    <property name="hibernate.ejb.naming_strategy" value="org.hibernate.cfg.ImprovedNamingStrategy"/>
    <!-- Begin DIW 5/1/11 new properties for caching -->
    <property name="hibernate.cache.use_second_level_cache" value="true"/>
    <property name="hibernate.cache.use_query_cache" value="true"/>
    <property name="hibernate.cache.region.factory_class" value="net.sf.ehcache.hibernate.EhCacheRegionFacto ry" />
    <!-- End DIW 5/1/11 new properties for caching -->
    <!-- Uncomment the following two properties for JBoss only -->
    <!-- property name="hibernate.validator.apply_to_ddl" value="false" /-->
    <!-- property name="hibernate.validator.autoregister_listeners" value="false" /-->
    </properties>
    </persistence-unit>
    </persistence>


    But I am wondering if I should even be using persistence.xml. Do I need a ehcache.xml instead. If so, how is it referenced?

    When I start my server I get the following error:

    SEVERE: Servlet.service() for servlet MenuLyzer threw exception
    org.springframework.beans.factory.NoSuchBeanDefini tionException: No bean named 'entityManagerFactory' is defined
    at org.springframework.beans.factory.support.DefaultL istableBeanFactory.getBeanDefinition(DefaultListab leBeanFactory.java:527)
    at org.springframework.beans.factory.support.Abstract BeanFactory.getMergedLocalBeanDefinition(AbstractB eanFactory.java:1083)


    I commented out the following inside my applicationContext.xml file.:

    <!-- DIW commented out 5/1/11
    <bean class="org.springframework.orm.jpa.JpaTransactionM anager" id="transactionManager">
    <property name="entityManagerFactory" ref="entityManagerFactory"/>
    </bean>
    <tx:annotation-driven mode="aspectj" transaction-manager="transactionManager"/>
    <bean class="org.springframework.orm.jpa.LocalContainerE ntityManagerFactoryBean" id="entityManagerFactory">
    <property name="dataSource" ref="dataSource"/>
    </bean>

    Thanks,

    Dan
