Java.io.CharConversionException:Not an ISO 8859-1 character:

Java.io.CharConversionException:Not an ISO 8859-1 character:xxx

This problem may be due to the effect of outputstream output Chinese characters.

Response.setcontenttype ("Text/html;charset=utf-8");
Response.getoutputstream (). Print ("Chinese text"); The guild went wrong.
Response.getwriter (). Print ("Chinese text"); Just change it.
Response.getwriter (). Close ();

The reason I personally think is because OutputStream is output string in bytes, it needs to conform to that ISO 8859-1 encoding, but the string to be output is UTF8 encoded, so there is a problem. But the root of the problem, I really did not figure out.

It would be nice to change into writer. Maybe it's the difference between the InputStream and the Reader,outputstream and writer.
