JRLoader: Error Loading Object from URL

2004-08-17 11:29



I'm writing an applet, based on the PrinterApplet in the webapp sample.


When I'm calling JRLoader.loadObject(), I'm getting the following error:


net.sf.jasperreports.engine.JRException: Error loading from URL:file:/D:/Data/java/report.pdf

at net.sf.jasperreports.engine.util.JRLoader.loadObject(JRLoader.java:186)


So, it's failing at this statement:


jasperPrint = (JasperPrint)JRLoader.loadObject(fileUrl);


fileUrl is the URL object that I've created from getCodeBase() and getParameter("REPORT_URL") -- just like in the original PrinterApplet.java.


I know I'm getting values back from the getCodeBase() and getParameter() calls -- hence the 'file:/D:/Data/java/report.pdf ' in the error.


Could anyone please tell me what I'm missing? Any help would be greatly appreciated.


Thank you,


Ken Hollister

well, according to your post, the filename that you are generating is for a PDF. The line of code that you pointed out as causing the error is expecting a *.jrprint file.


I would expect the pdf filename to be the OUTPUT file. The call that you are making appears to be looking for the input file.

Thanks for the explanation... apparently I've mistunderstood the purpose of the PrinterApplet sample.


As I already have a report in PDF format, I'll just use iText to open the file and print it.


Thanks again,
