I'm trying to generate a report using JaperReports, but when I click
generate the following error appears in eclipse:
[WARN] /seringueira/resumosafra

In class Impl I use the following:
if(bytes != null && bytes.length > 0) {
getThreadLocalResponse().setContentType("application/pdf");
getThreadLocalResponse().setContentLength(bytes.length);
try {
ServletOutputStream ouputStream =
getThreadLocalResponse().getOutputStream();
ouputStream.write(bytes, 0, bytes.length);
ouputStream.flush();
ouputStream.close();
} catch(Exception ex) {
ex.getMessage();
}
}
Does anyone have any idea what I might be doing wrong?
