Hi guys,

I'm using Spring and Hibernate in my Web application. When I try to access a hibernate object from my struts action class or my JSP page, I get an exception stating:

Uncaught exception thrown in one of the service methods of the servlet: action. Exception thrown : javax.servlet.ServletException: could not initialize proxy - the owning Session was closed

Does anyone know what I'm doing wrong and how to solve the problem.

Here's my code:


/////WEB.XML//////////////

<!-- =================== Define Spring Bean Definition Files to be loaded ================== -->

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:com/PBCoreApp/architecture/applicationContext.xml</param-value>
</context-param>
<!--
<context-param>
<param-name>parentContextKey</param-name>
<param-value>pb.model</param-value>
</context-param>
-->
<filter>
<filter-name>hibernateFilter</filter-name>
<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
<init-param>
<param-name>singleSession</param-name>
<param-value>true</param-value>
</init-param>
</filter>

<filter-mapping>
<filter-name>hibernateFilter</filter-name>
<url-pattern>*.do</url-pattern>
</filter-mapping>



<!-- =================== Spring Context Loader Servlet ================== -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>


////JAVA CODE//////

BusinessServiceCbo businessServiceCbo = new
BusinessCbo businessCbo = new BusinessCbo();
businessCbo = businessDao.findById(businessId);

List serviceList = new ArrayList( businessCbo.getBusinessServices());
businessDetailsDto.setServiceList(serviceList);

//////ACTION CLASSS///

System.out.println("Service List: " + businessDetailDto.getServiceList()); //error occurs here!!!


///APPLiCATION Context.xml /////

<bean id="businessBSTarget" class="com.PBCoreApp.business.impl.BusinessBSImpl">
<property name="businessDao"><ref local="businessDao" /></property>
</bean>
<bean id="businessBS" class="org.springframework.aop.framework.ProxyFactoryBean">
<property name="proxyInterfaces">

</property>
<property name="target">
<ref local="businessBSTarget" />
</property>
<property name="interceptorNames">
<list>
<value>hibernateInterceptor</value>
</list>
</property>
</bean>


/////STRUTS-CONFIG//////

<!-- ============================= Spring Plugin ================================== -->

<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property
property="contextConfigLocation"
value="/WEB-INF/presentationContext.xml classpath*:com/PBCoreApp/architecture/applicationContext.xml" />
</plug-in>


Pls...HeLP!!!
