Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere eXtreme Scale * * Version 7.0 who are using the HTTP session * * replication support. * **************************************************************** * PROBLEM DESCRIPTION: A DuplicateKeyException exception * * results when a Web application updates * * objectgrid.session.metadata map. * **************************************************************** * RECOMMENDATION: * **************************************************************** Certain Web applications make nested requests to different servlets using the same session. Nested calls to the getSession method should return the HTTP session that was created in the first request, but the eXtreme Scale HTTP session filter attempted to create a new HTTP session on each of the nested requests. Because these requests shared the same session ID, a DuplicateKeyException exception resulted.
Problem conclusion
The WebSphere eXtreme Scale HTTP session replication was corrected to process nested Web application requests in the proper order.
