i was trying seam 1.3.0. i created a new seam project, added a few entity classes. it has successfully deployed. After that i wanted to try pdf component. therefore i made these changes: in components.xml: added a pdf name space and this declaration <pdf:document-store use-extensions="true" /> in web.xml: added these lines <servlet-name>Document Store Servlet</servlet-name> <servlet-class>org.jboss.seam.pdf.DocumentStoreServlet</servlet-class> <servlet-mapping> <servlet-name>Document Store Servlet</servlet-name> <url-pattern>*.pdf</url-pattern> </servlet-mapping> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4054593#...
