Transaction, AOP and my own aspects

[MmarcoM]

hi all,
i have written a PersistenceManager component that uses HibernateDAOSupport to interact with the database.
Following some examples on a tutorial, i have declared transaction in applicationContext.xml, like following

<code>
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<!--
- Application context definition for JPetStore's business layer.
- Contains bean references to the transaction manager and to the DAOs in
- dataAccessContext-local/jta.xml (see web.xml's "contextConfigLocation").
-->
<beans>

so i have declared my PersistenceManager as a TransactionProxyFactoryBean.
the problem is that i have also written my own advisors to be applied to persistenceManager, and i am receiving the following exception when my application is started:

2005-02-17 21:59:04,515 ERROR [org.jboss.web.localhost.Engine] StandardContext[/budget-web]StrutsActionServlet: null
org.springframework.beans.factory.BeanCreationExce ption: Error creating bean with name 'persistenceManager' defined in resource [/WEB-INF/applicationContext.xml] of ServletContext: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyExcep tion: Invalid property 'interceptorNames' of bean class [org.springframework.transaction.interceptor.Transa ctionProxyFactoryBean]: Property 'interceptorNames' is not writable
org.springframework.beans.NotWritablePropertyExcep tion: Invalid property 'interceptorNames' of bean class [org.springframework.transaction.interceptor.Transa ctionProxyFactoryBean]: Property 'interceptorNames' is not writable


Question is: how can i declare interceptorNames and
transactionAttributes on the same bean? which type of class will it be?

thanx in advance and regards
marco

Try:

<property name="preInterceptors">
<list>
<ref local="beforeAdvisor"/>
<ref local="queryAdvisor"/>
</list>
</property>
<property name="postInterceptors">
<list>
<ref local="afterAdvisor"/>
</list>
</property>

Take a look at the API for TransactionProxyFactoryBean (http://www.springframework.org/docs/api/org/springframework/transaction/interceptor/TransactionProxyFactoryBean.html). You can see what properties can be set there and in its superclasses
