Here is a simple example with which you can compare
public class ExportXML {
StreamResponse onActivate(){
return new StreamResponse() {
@Override
public String getContentType() {
return "text/xml";
}
@Override
public InputStream getStream() throws IOException {
String xml = "<?xml version='1.0'?>\n" +
"<message>Hello</message>";
ByteArrayInputStream in = new ByteArrayInputStream(
xml.getBytes()
);
return in;
}
@Override
public void prepareResponse(Response response) {
}
};
}
}
BTW what tapestry version are you using( just to ensure we are dealing with
tapestry5 :))
Also I remember one case where a developer had implemented StreamResponse as a
public class in the pages sub-package. That can also lead to this issue.
