Hi,

My application has only EJB project and no Web tier.
I want to implement spring declarative transaction management using AOP.
How to load the spring context xml?

Thanks in advance,

Unfortunately, the only solution with EJBs is to have your EJBs extend the Spring class that makes EJB Spring App Context aware.

Good Luck

Mark

I am NOT using EJBs (Session beans) for Transaction Management. I want to use Spring POJO Declarative Transaction Management using AOP. Only entry point to the application is MDB.
Since there is not web project, I am not sure how to load the application context xml where the transaction attributes are defined and let the container be aware of it.

<bean id="sampleManager" class="test.SampleManager">
<property name="dataAccessor" ref ="dataAccessor"/>
<property name="dataSource">
<ref local="dataSource"/>
</property>
</bean>

<tx:advice id="txAdvice" transaction-manager="txManager">
<tx:attributes>
<tx:method name="get*" read-only="true"/>
<tx:method name="*" propagation = "REQUIRED"/>
</tx:attributes>
</tx:advice>

<aop:config>
<aop:pointcut id="testOp" expression="execution(* test.SampleInterface.*(..))"/>
<aop:advisor advice-ref="txAdvice" pointcut-ref="testOp"/>
</aop:config>

<bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
</beans>

SampleManager implements SampleInterface.


Could you please help on this? Thanks.

you can try this, have a web.xml and define a servlet in it like:


then define a main class like:

Thanks Vivek. But want to know, Can we use web.xml in EJB project?
How this web.xml will be triggered. I dont have any web module/project at all. My application is triggered using MDB.

yes you can do that: http://www.eclipse.org/webtools/community/tutorials/ejbtutorial/buildingejbs.html

Also, there are other ways to do this as well. You can have a main method to load the Spring beans. Where to trigger it from can be a bit tricky...

Thanks. I will try this option.
Once loaded using the above method, the container will take care of the transaction using the attributes in the context xml right ?
