Hi ! I have the same problem as littleprince. Streaming a PDF through a portlet with resourceServing works fine with the JSPHelloUserPortlet Example. (I'm using the bundle JBoss AS 4.2.3 + Portal 2.7.0 CR 1) But if it put the code in a Richfaces Example i get the same nonesense as littleprince wrote: the result i got is | %PDF-1.4 %âã Where lies the problem ? Is ist the jboss portlet bridge ? I am using the RBasic RichFaces Project from the Wiki JBoss Bridge Getting Startet http://www.jboss.org/community/docs/DOC-12740.
