I'm experiencing a strange problem. When deploying my Tapestry 4 application directly in Tomcat 5.5.20, it runs perfectly, and my localized messages (rendered using ) are output as UTF-8 strings, and the HTTP response headers and HTML headers says that the content type is "text/html;charset=UTF-8". So far, so good. BUT, when I fire up my JBoss 4.0.5GA which has an embedded Tomcat 5.5.20 and I deploy my Tapestry application, the localized messages suddenly render as iso-8859-1 but the HTTP response headers and HTML headers still tell the same content type, namely UTF-8. This means that all non-ascii characters show up as ? in my browser because my iso-8859-1 output is parsed as UTF-8 by the browser. Do anyone have any past experiences on what causes my problem? Do anyone have a solution? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3983839#...
