Cannot resolve Struts2 NotSerializableException ev

Question

I currently doing a work with struts2 and this error suddenly appears. Some cache of my objects is not working.

I use JBoss 5 and struts2 : struts2-core-2.3.4.1.jar xwork-core-2.3.4.1.jar

The stack trace is here : http://pastebin.com/QpPV01wX

this is some snippet :

I would love suggestions or might be something wrong I did.

Thank you very much in advance,

I tried to remove token session interceptor that I used in my struts.xml and the problem is gone. Still, I dont know why it went wrong if I use token. At least in my case, it is solved by removing token session interceptor.

I remove following line on struts.xml

<interceptor-ref name="tokenSession">
  <param name="excludeMethods">list</param>
  <param name="includeMethods">save,update</param>
</interceptor-ref>

Answer 1

Seems you have put Objects into the cache or your session that do not implement java.io.Serializable.

Answer 2

I also meet the same problem, but I finnaly find my struts2-spring-plugin-2.0.14.jar doesn't match my struts2-core.2.2.3.jar, so I replaced the struts2-spring-plugin with the corresponding version and it's working~ good luck~ hope this helpful for other people~

Answer 3

I solved that problem by switching to tokenInterceptor in place of tokenSessionInterceptor. tokenInterceptor is ok for most of the cases.

Answer 4

Ran into this issue with struts-2.3.32 as well. The com.opensymphony.xwork2.DefaultActionInvocation class has a reference to the Action.
If your action extends com.opensymphony.xwork2.ActionSupport then it references the com.opensymphony.xwork2.inject.Container.
The workaround is to remove the dependency on ActionSupport.
