Session bean and util:map : NotSerializableException

[werdex]

Hi all,
I have a session bean where map is inserted using util:map namespace:
<beans:bean id="mySuperBean"
class="com.SuperBeanImpl"
scope="session">
<aop:scoped-proxy proxy-target-class="false"/>
...
<beansroperty name="superMap">
<util:map>
</util:map>
</beansroperty>

The bean failed to serialize on tomcat stop:
Caused by: java.io.NotSerializableException: org.springframework.beans.factory.config.MapFactor yBean
at java.io.ObjectOutputStream.writeObject0(ObjectOutp utStream.java:1164)

Is it possible to make util:map serializable? How to apply aop:scoped-proxy to it?

Solved the problem by defining util:map beans separately

<beans:bean id="mySuperBean"
class="com.SuperBeanImpl"
scope="session">
<aop:scoped-proxy proxy-target-class="false"/>
...
<beansroperty name="superMap" ref="myMap1"/>

<util:map id="myMap1">
</util:map>

<util:map id="myMap2">
</util:map>
