Shane said that the SeamMultipartFilter has been replaced with a universal Seam filter, but in the s:fileUpload section in 1.1.7 RC1 docs, the SeamMultipartFilter is still there: For multipart requests, the Seam Multipart servlet filter must also be configured in web.xml: | | | <filter> | <filter-name>Seam Multipart Filter</filter-name> | <filter-class>org.jboss.seam.servlet.SeamMultipartFilter</filter-class> | </filter> | | <filter-mapping> | <filter-name>Seam Multipart Filter</filter-name> | <url-pattern>*.seam</url-pattern> | </filter-mapping> Should it be replaced by <filter> | <filter-name>Seam Filter</filter-name> | <filter-class>org.jboss.seam.web.SeamFilter</filter-class> | </filter> | | <filter-mapping> | <filter-name>Seam Filter</filter-name> | <url-pattern>/*</url-pattern> | </filter-mapping> In addition, it seems that s:fileUpload attributes missed the fileSize attribute in 1.1.7 docs of s:fileUpload section.
