Java EE (Java Enterprise Edition) General Discussion

We are running into a problem where our generated SOAP XML contains non-UTF8 characters. These characters are not properly escaped and the XML encoding tag is set to:

<?xml version="1.0" ?>

Clients thus assume the encoding is UTF-8 which in turn causes the following exception to be thrown:

javax.xml.ws.WebServiceException: javax.xml.bind.UnmarshalException
- with linked exception:
[javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,38912]
Message: An invalid XML character (Unicode: 0x1a) was found in the element content of the document

Is there a way to configure JAX-WS (or JAXB) to escape non-UTF-8 characters? Or a way to configure JAX-WS (or JAXB) to have the proper character encoding set in the XML encoding tag?

Thanks for your help,
