There is a detailed description of this issue in the Spring Portlet MVC FAQ:

I found the solution in the mailing list archives.  I needed to add
emptySessionPath="true" to the connector element in tomcat's server.xml
file.  So it looks like this:

 <Connector port="8080" maxHttpHeaderSize="8192"
               maxThreads="150" minSpareThreads="25"
maxSpareThreads="75"
               enableLookups="false" redirectPort="8443"
acceptCount="100"
               connectionTimeout="20000" disableUploadTimeout="true"
emptySessionPath="true"/>


Thanks,
Brice

        I would like to set a session variable in a servlet and retrieve it in
a portlet.  Both are in the same application, but it doesn't appear to
work.  I've set an attribute using the HttpSession in a servlet, but the
attribute is null when I try to get it using the PortletSession.  I've
tried it the other way also, setting a variable in a portlet and trying
to retrieve it in a servlet.  That also does not work.  Is there any way
to accomplish this?

Be sure you use PortletSession.APPLICATION_SCOPE, not PortletSession.PORTLET_SCOPE (this is a default for the second method argument).
