I have deployed my web app in Tomcat container.Below is my app context,
<bean id="entityManagerFactory"
class="org.springframework.orm.jpa.LocalContainerE ntityManagerFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.OpenJpaV
endorAdapter">
<property name="showSql" value="false"/>
<property name="generateDdl" value="true"/>
<property name="databasePlatform"
value="org.apache.openjpa.jdbc.sql.OracleDictionar y"/>
</bean>
</property>
<property name="jpaPropertyMap">
<map>
<entry key="openjpa.jdbc.DBDictionary"
value="org.apache.openjpa.jdbc.sql.OracleDictionar y"/>
<entry key="openjpa.Log" value="DefaultLevel=WARN,
Runtime=TRACE, SQL=TRACE"/>
</map>
</property>
<property name="loadTimeWeaver">
<bean class="org.springframework.instrument.classloading
.SimpleLoadTimeWeaver"/>
</property>
</bean>
<bean id="jpaTemplate" class="org.springframework.orm.jpa.JpaTemplate">
<property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>
<bean name="transactionManager"
class="org.springframework.orm.jpa.JpaTransactionM anager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
<property name="dataSource" ref="dataSource"/>
</bean>
<tx:annotation-driven />
I am using Spring's OpenEntityManagerinView filter as below in my web.xml,
<filter>
<filter-name>JpaFilter</filter-name>
<filter-class>org.springframework.orm.jpa.support.OpenEnti
tyManagerInViewFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>JpaFilter</filter-name>
<url-pattern>*.do</url-pattern>
</filter-mapping>
All my service implementation methods are marked @Transactional.
I get a TransactionRequiredException when calling entityManager.lock(entity);
method
I am able to successfully merge() entities and my persistence context type is
the default "Transaction..."
When i debug, entitymanager.getTransaction() throws a
IllegalStateException and entityManager.getTransactionalObjects()
returns an empty collection.
Is the Transaction never started ?
How do check this?
Any help will be greatly appreciated.
