Hi Baptiste, how is your "filter-mapping" defined in web.xml ? This looks like you map the filter to all URLs, including images, css, non-database-dependent HTML and so on ... you should map the filter only to those URLs which actually use the hibernate session. This is a little difficult, though, as web.xml url-patterns are not very powerful. "See SRV.11.2 Specification of Mappings" from the servlet spec., V 2.3, for more info, if this turns out to be the problem.
Regards, Johannes
