compile and create pdf on fly

[boomramada]

Hello,

Im new to jasper, just a quick question, do i have to compile and save to file before convert to the pdf.

or could able to compile and run on the fly from the jrxml.

eg:

byte[] cr = JasperCompileManager.compileReportToFile(
                   path + "Report.jrxml").getBytes();

ByteArrayInputStream is = new ByteArrayInputStream(cr);

 JasperRunManager.runReportToPdfStream(is,
                    servletOutputStream, new HashMap(), new JREmptyDataSource());

 

Is it possible? however, that gives an net.sf.jasperreports.engine.JRException: Error loading object from InputStream

compileReportToFile returns the name of the compiled file.

What you can do is to call compileReport to return a JasperReport instance, save it to a file using JRSaver and use it directly in JasperRunManager.

HTH,
