Hi,

I am using alfresco 3.2r over jdk 6, tomcat & windows. I have integrated alfresco explorer as a iframe portlet in liferay 5.2.3 which is running on tomcat, jdk6 & windows on another machine.At times, i encounter the error on my iframe portlet:

HTTP status 500
The server encountered an internal error that prevented it from fulfilling the request.
exception
org.hibernate.exception.genericjdbc exception:could not load an entity:[org.alfresco.repo.domain.hibernate.nodeimpl…]
org.hibernate.exception.sqlstateconverter.handlenonspecificexception….
org.alfresco.repo.node.db.hibernate.hibernatenodedaoserviceimpl.getnodeornull(hibernatenodedaoserviceimpl…)
…..

On checking in alfresco.log, i see following exception:

I am not sure what is causing the error as this exception suddenly appears in perfectly running system when user clicks on a link provided for alfresco portlet.

Is this an alfresco issue? or a liferay issue? or some other generic issue?Any help will be highly appreciated.
