http://issues.apache.org/bugzilla/show_bug.cgi?id=37072 Summary: Encoding mismatch in error condition Product: Tomcat 5 Version: 5.5.9 Platform: Other OS/Version: other Status: NEW Severity: normal Priority: P2 Component: Catalina AssignedTo: tomcat-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] I found a possible bug in the class org/apache/catalina/connector/Response.java. I try to explain the problem with steps of the request flow (I use a filter, a servlet and a JSP page): 1. Tomcat gets a request from outside 2. The filter gets the response and does the following: 2.1 Sets the character encoding to UTF-8 2.2 Gets the writer with response.getWriter() and writes out a message if the content type is text/html. This locks the writer which means you can not set the character encoding later anymore. 3 The servlet gets the request and an exception occurs (this is a simulated exception) 4 Tomcat gets back the request and processes the error 4.1 The response is reset: 4.1.1 the response itself is reset 4.1.2 the outputstream is reset 4.1.1+2 both are reset to ISO-8859-1 which is the default value. 5 The error page is called which has the encoding UTF-8. 5.1 BUG: The encoding of the page is not used because the writer is still locked but the encoding in the writer is set to default which is ISO-8859-1 My suggestion is to let the character encoding be untouched in the error case because in the error case the encoding was already set somewhere before (e.g. filter or servlet). 1. Tomcat (ISO-8859-1, writer unlocked) 2. Filter (-> UTF-8, writer locked) 3. Servlet (UTF-8, exception raised, writer locked) 4. Tomcat (ISO-8859-1, writer locked) 5. JSP (UTF-8 <-> ISO-8859-1 conflict because writer still locked -> setCharacterEncoding is locked) With regards Udo Walker -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
