Jasper will raise an error like /WEB-INF/tags/sampletaglib/sampletag.tagx(3,99) Page-encoding specified in XML prolog (iso-8859-1) is different from that specified in page directive (ISO-8859-1) if the encoding specified within the XML prolog and the page directive use different casing: <?xml version="1.0" encoding="iso-8859-1"?> <jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.0"> <jsp:directive.tag display-name="sampletag" pageEncoding="ISO-8859-1" /> This is a sample tag! </jsp:root> Proposed solution: Compare the encodings case-insensitive. For example: iso-8859-1 and ISO-8859-1 are both valid identifiers for the same encoding.
Looks like I missed a case when I fixed 44986. Trunk has been fixed and the patch proposed for 6.0.x
This has been fixed in 6.0.x and will be included in 6.0.19 onwards.
