Weblogic 12c - The session data could not be deserialized

[Spyridon Doulgeridis, modificado hace 8 años.]

Hi all,

We are using Liferay 6.2 EE and WLS 12.1.2. The WLS domain is a standalone in DEV mode.
We have created some portlets with Spring .4.1.5.RELEASE and Lifray JSP tags.
With Tomcat it works ok.

There are deployed ok, but we get the exception below when performing hte following scenario:
1. We are performing an ActionRequest in portlet.
2. in which we get a list of data which are displayed ok.
3. After that we get the exception below in the console

Hmmm maybe there are more than one Spring libraries in classpath.

If you are adding your own Spring libraries, maybe you want to add those in <prefer-application-packages>?

Hi Juan,

First of all, Thanx a lot for the quick reply.

We are using maven and we indeed declare our Spring dependencies. We did some attempts to add this in weblogic.xml of the portlet.

Do we need to put it in all wars: portlets and main portal war?

Thanx in advance!

It depends on which classloader that class was loaded from. To see that, it would be necessary to check the complete stacktrace at least.

Hello,

I would like to inform you that this error exists only in CE edition not in EE. I used the same portlet with the CE edition of liferay and I got the serialization error message that Spyros said.

<Jan 7, 2016 5:11:10 PM EET> <Error> <HTTP Session> <BEA-100028> <The session data could not be deserialized.

When I used the EE edition and I deployed the same portlet that message did not display on the console.
The tests that I did were with weblogic 12 and liferay-portal-6.2-ce-ga4-20150416163831865

Thank you,
Nikos

Have you found the origin of this problem? I have encountered exactly the same exception:

Caused by: java.io.InvalidClassException: org.springframework.ui.ModelMap; local class incompatible: stream classdesc serialVersionUID = 1954789964718618214, local class serialVersionUID = 5665110590241200972
