Hi all, linked to my pull request #19 to fix ARIES-1023 and ARIES-1079, I'd like to discuss with you another feature. In my system I'm using spring-orm to create an EntityManagerFactory to be injected into my data service. I use a persistence.xml with only classes list and NO properties declared. I use the spring file to define the jpa properties in this way
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns:context=" http://www.springframework.org/schema/context"; xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd";> <osgix:cm-properties id="dataSourceProperties" persistent-id="sensormix.jpa.persistenceunit"> <prop key="sensormix_db.driverClassName">org.hsqldb.jdbcDriver</prop> <prop key="sensormix_db.url">jdbc:hsqldb:mem:sensormix_db</prop> <prop key="sensormix_db.username">sa</prop> <prop key="sensormix_db.password"></prop> </osgix:cm-properties> <context:property-placeholder properties-ref="dataSourceProperties" /> <bean id="emf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="persistenceUnitName" value="sensormix_db" /> <property name="jpaVendorAdapter"> <bean class="org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter"> <property name="showSql" value="true" /> </bean> </property> <property name="jpaProperties"> <props> <prop key="eclipselink.ddl-generation">create-tables</prop> <prop key="eclipselink.logging.level">INFO</prop> <prop key="eclipselink.weaving">false</prop> <prop key="javax.persistence.jdbc.driver">${sensormix_db.driverClassName}</prop> <prop key="javax.persistence.jdbc.url">${sensormix_db.url}</prop> <prop key="javax.persistence.jdbc.user">${sensormix_db.username}</prop> <prop key="javax.persistence.jdbc.password">${sensormix_db.password}</prop> </props> </property> </bean> <!-- Beans of Test Application --> <bean id="sensormixService" class="com.google.developers.gdgfirenze.dataservice.SensormixServiceJpaImpl"> <property name="entityManagerFactory" ref="emf" /> </bean> </beans> As you can see, some values are parameters that are set using the property-placeholder. I think this is a very convenient way to manage the dynamic change of jpa properties. I try to do the same with Aries Jpa, in this way <?xml version="1.0" encoding="UTF-8"?> <blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"; xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0"; xmlns:jpa="http://aries.apache.org/xmlns/jpa/v1.0.0"; xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.osgi.org/xmlns/blueprint/v1.0.0";> <cm:property-placeholder persistent-id="sensormix.jpa.persistenceunit" update-strategy="reload" > </cm:property-placeholder> <bean class="com.google.developers.gdgfirenze.dataservice.SensormixServiceJpaImpl"> <jpa:unit property="entityManagerFactory" unitname="sensormix_db" /> <jpa:context property="entityManager" unitname="sensormix_db"> <jpa:map> <entry key="eclipselink.ddl-generation" value="create-tables" /> <entry key="eclipselink.logging.level" value="INFO" /> <entry key="javax.persistence.jdbc.driver" value="${sensormix_db.driverClassName}" /> <entry key="javax.persistence.jdbc.url" value="${sensormix_db.url}" /> <entry key="javax.persistence.jdbc.user" value="${sensormix_db.username}" /> <entry key="javax.persistence.jdbc.password" value="${sensormix_db.password}" /> </jpa:map> </jpa:context> </bean> </blueprint> but it seems that the NSHandler class is not able to resolve the parametric value. I think this is because the properties map is in the jpa namespace. Do you think that this is a new feature that we can add to Aries Jpa? Regards Giuseppe
