When i uploaded file with non ASCII character, i have error:
HTTP JVM: error: java.io.CharConversionException: Not an ISO 8859-1 character: ?
[08420:00022-3033504624] 01/16/2013 19:05:14 HTTP JVM: com.ibm.xsp.webapp.FacesServlet$ExtendedServletException: java.lang.IllegalStateException: Can't get a Writer while an OutputStream is already in use
So, where i can change encoding?
