Session Replication in Cluster Environment

[Subhasis Roy，修改在9 年前。]

Hi,

I have used PortletSession in APPLICATION_SCOPE in liferay, but its not working in cluster environment.

Error in Cluster Environment:
Caused by: java.lang.IllegalArgumentException: JBAS018062: 'employeeBean' attribute with type 'com.test.portlet.command.data.EmployeeBean' cannot be replicated
at org.jboss.as.web.session.ClusteredSession.setAttribute(ClusteredSession.java:824)
at org.apache.catalina.session.StandardSessionFacade.setAttribute(StandardSessionFacade.java:130)
at com.liferay.portlet.PortletSessionImpl.setAttribute(PortletSessionImpl.java:200)

"employeeBean" is a POJO object stored in the session and used in all the portlets. As per my understanding this issue is caused because Session is not replicated properly in all the nodes in the cluster.
Please correct my understanding, if wrong.

Is there any draw backs if we configure session replication in cluster environment for Life ray portal.

Thanks,
subhasis

Hi Subhasis,

Since its a clustered environment.Please make sure "Sticky Session" enabled in that environment.

The whole point of using Session Replication is that the session does not necessarily have to stick to one node in the cluster.

Hi Subhasis,

all session objects should implement Serializable, please check that.

Hi Juan,

All the all the bean objects are serializable and also added <distributable/> tag in the web.xml

but still its giving same issue.

Check if all attributes of that POJO are implementing Serializable too, all the clues points to that direction.

Hi Juan,

It worked. Thanks a lot.

Making the POJO class Serializable and adding the <distributable/> tag in web.xml file worked.

I had cleared the tmp folder of the JBOSS and made a fresh deployment. It's working fine.
