Scope Session Bean Problem

[roninken]

Hi

I am developing a J2EE application with Spring MVC, ZK, and ACEGI, and I have next problem:

I need inject a Session bean (new Spring Scope) in other bean that is not session, (maybe singleton), the applicationContext.xml source is:



<bean id="testBean" class="scope.TestBean" scope="session">
<aop:scoped-proxy/>
</bean>
<bean id="testBean2" class="scope.TestBean2">
<property name="testBean" ref="testBean"/>
</bean>


I set the web.xml file and i put the correspondig listener:



<listener>
<listener-class>
org.springframework.web.context.request.RequestCon textListener
</listener-class>
</listener>


The previous code i think is ok, even, the tomcat server running well, but, when I create the bean Instance whit zk Event:



private ITestBean2 testBean2 = (ITestBean2) SpringUtil.getBean("testBean2");
private ITestBean testBean = testBean2.getTestBean();
public void TestBean()
{
testBean2.setId(1);
testBean.setId(1);
System.out.println("["+testBean2.getClass().getName()+"] Id: "+testBean2.getId());
System.out.println("["+testBean.getClass().getName()+"] Id: "+testBean.getId());
}


the application shows the next error:

What happen?

Ahh, my english is wrong, excuse me plase.

I think you must configure a RequestContextFilter in your web.xml:


<filter>
<filter-name>requestContextFilter</filter-name>
<filter-class>org.springframework.web.filter.RequestContextFilte r</filter-class>
</filter>
<filter-mapping>
<filter-name>requestContextFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

Thanks, but the RequestContextFilter is in the web.xml file.

I think that are acegi's filters the responsible of problem.

and you?


Please, help me !!

Maybe you want to take a look of this regarding ZK and Spring Framework.
http://www.zkoss.org/javadoc/3.0.3/zkplus/org/zkoss/zkplus/util/ThreadLocalListener.html

[roninken]

Thanks, this is the true Solution !!!

Hi roninken,

If you don't use ZK's Modal window, you can "disable" ZK's event thread mechanism entirely (so you don't have to add that ThreadLocalListener for such case). And ZK shall run faster since that avoid the thread switching overhead.

Add following line in WEB-INF/zk.xml and it will disable ZK's event thread mechanism (but it will also disable the Modal window mechanism since Modal window is based on event thread mechanism) :

<system-config>
...
<disable-event-thread/>
...
</system-config>

Hi Roninken,

I wonder if you had solved your problem about failing session scope bean failing to be created...

I know have the same problem, using ZK and Spring... I try adding the listener, the filter, both or them, and nothing worked :(
I try to add the "ThreadLocal" preference in ZK configuration but it didn't worked either...

Please if you succeeded in creating session scoped bean, tell me how, this is running me mad...

(My english is not too good either, sorry...)

Ok, I solved that... I hadn't specified "<aop:scoped-proxy/>" in the definition of the bean...

BTW, do you know what exactly this mean ?
