java.io.NotSerializableException error

[igod]

Hi,

I modify Contacts sample to use EhCacheBasedAclEntryCache,

   <bean id="aclCacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"/>
    
   <bean id="aclCacheBackend" class="org.springframework.cache.ehcache.EhCacheFactoryBean">
      <property name="cacheManager">
         <ref local="aclCacheManager"/>
      </property>
      <property name="cacheName">
         <value>aclCache</value>
      </property>
      <property name="timeToIdle">
      	<value>1800</value>
      </property>
      <property name="timeToLive">
      	<value>1800</value>
      </property>      
   </bean>
   
   <bean id="aclCache" class="net.sf.acegisecurity.acl.basic.cache.EhCacheBasedAclEntryCache">
   		<property name="cache"><ref local="aclCacheBackend"/></property>
   </bean>  
   
   <bean id="basicAclProvider" class="net.sf.acegisecurity.acl.basic.BasicAclProvider">
      <property name="basicAclDao"><ref local="basicAclExtendedDao"/></property>
      <property name="basicAclEntryCache"><ref local="aclCache"/></property>
   </bean>

when I try to execute, with 10000 contacts I obtain following error:

[DEBUG,ContactManagerBackend,http-8080-Processor25] Returning all contacts

I see ehcache documentation and objects in cache have to be serializable.

I do anything wrong, or AclEntry has to serializable ?

Thanks,
Paulo

Just a quick look at the source - it doesn't appear to implement Serializable, so I'd post a bug.

Fixed in CVS.

Nice turnaround time.
