Hi Gavin, I made it works for FileUpload on Seam + myface/tiles + myface(tomahawk). What I did is as follows: 1) Follow seam wiki fileUpload all steps, except the tomahawk.jar. 2) Put the tomahawk.jar into jboss-4.0.4.GA\server\default\deploy\jbossweb-tomcat55.sar\jsf-libs; 3) Modify the web.xml under jboss-4.0.4.GA\server\default\deploy\jbossweb-tomcat55.sar\conf:<init-param> | <description>MyFaces tlds</description> | <param-name>tagLibJar0</param-name> | <param-value>jsf-libs/myfaces-impl.jar</param-value> | </init-param> | <!-- I added the tomahawk --> | <init-param> | <description>MyFaces tlds</description> | <param-name>tagLibJar1</param-name> | <param-value>jsf-libs/tomahawk.jar</param-value> | </init-param> 4)Put the struts.jar into jboss-4.0.4.GA\server\default\deploy\jbossweb-tomcat55.sar. Thank you, Gavin. Gus View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3959752#...
