Create minimal report with only detail band with a simple barcode (barcode4j) code128 with fixed code "123456789"
Link org.krisalis barcode4j.jar ver2.1 in lib directory of web application
After compile and fill the report the servlet out with:
and error in tomcat is:
getOutputStream() has already been called for this response
seem that are no stream in response.
If i delete barcode component and add a simple text component all run correctly and servlet response with pdf stream in browser
