I'm using JBoss on a server with french locale. All the pages displayed (JSP, servlets) are displaying correctly. However, the error pages have a strange encoding (it is (correctly) interpreted by firefox as UTF-8). For example, the 404 error page displays: anonymous wrote : Etat HTTP 404 - /SIT/index.j | | type Rapport d'�tat | | message /SIT/index.j | | description La ressource demand�e (/SIT/index.j) n'est pas disponible. | JBoss Web/2.1.3.GA Thus it seems all pages directly generated by tomcat have the wrong encoding (encoded twice ?). The logs from JBoss about tomcat shows the same behaviour: anonymous wrote : | 13:53:11,780 INFO [Http11Protocol] D�marrage de Coyote HTTP/1.1 sur http-localhost%2F127.0.0.1-8080 | 13:53:11,858 INFO [Http11Protocol] D�marrage de Coyote HTTP/1.1 sur http-localhost%2F127.0.0.1-8443 Note: previewing this post, the special characters are re-interpreted and doesn't look the same as displayed in firefox.
