i need more documentation on applicationContext.xml
hi, i've been reading and studying
http://struts.apache.org/2.0.14/docs/struts-2-spring-2-jpa-ajax.html.
i want to know what is actually going on in applicationContext.xml.
for example, what do these two lines do? please explain or refer me to
better documentation.
<bean id="transactionManager"
class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
<tx:annotation-driven transaction-manager="transactionManager" />

thanks Martin. that gives me a little more confidence. that takes a
little mystery away from that XML file.
by the way, do you know any books that discusses Struts 2 (the latest
latest version 2.1.x)? i would purchase it in a heartbeat.

a listing of persistence-providers
//notice the vendorAdapter changes for every vendor
Toplink: <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
vendorAdapter
<bean class="org.springframework.orm.jpa.vendor.TopLinkJpaVendorAdapter">
<property name="database" value="HSQL"/>
<property name="showSql" value="true"/>
<property name="generateDdl" value="true"/>

</bean>
TransactionManager: ?
Hibernate: <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="jpaVendorAdapter">

<property name="database" value="HSQL"/>
<property name="showSql" value="true"/>
<property name="generateDdl" value="true"/>
</bean>
</property>
TransactionManager: ?
//Spring SharedEntityManager supports EntityManagerFactory thru transactionManager:
<bean id="entityManager" class="org.springframework.orm.jpa.support.SharedEntityManagerBean">
<property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>
//transactionManager
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory"/>
<property name="dataSource" ref="dataSource"/>
</bean>
conclusion seems to be we can implement both the entityManager and transactionManager
but only if wholly configured to use entityManagerFactory's (based on jpaVendorAdapter vendor specific configuration)

Hi Jake,
the <tx:annotation-driven /> simply tells Spring to put transactional
advice on any class or method that has an @Transactional annotation on it.

Stephen,
i know it is a spring xml file. i can tell that with the <bean
id="transactionManager".../> element, they are defining a transaction
manager. however, what does <tx:annotation-driven transaction-manager
.../> do? to me, intuitively, it defines a transaction manager that
will process by annotations.
the tutorial that gives this applicationContext.xml shows us how to
get things working, but doesn't really explain in detail "why" we are
doing what we are doing. that's kind of what i meant.

Hi Jake,
This file holds the Spring configuration. You'll need to read up on Spring
- they have excellent documentation at:
