This is not a bug. The problem is with the URIEncoding. If you are using Tomcat or JBoss all you have to do is either set useBodyEncodingForURI="true" which will use your page's character encoding to encode URIs or set URIEncoding to whatever character encoding you are using for the tomcat Connector in the server.xml. The default encoding is ISO-8859-1 for Tomcat if not set explicitly. <Connector port="8080" ..... useBodyEncodingForURI="true" ..../> <Connector port="8080" ..... URIEncoding="UTF-8" ..../> Ramazan YILDIRIM View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4054383#...
