HELP : loading jasperPrint object from URL

2006-02-08 19:24

When I enter this URL to the address bar, it does display a PDF report :

http://localhost:8080/LePere0.1/jasperreport/rpt_Applet?reporttype=PDF

with 'jasperreport' is the servlet mapping parameter pointing to a servlet, and that servlet works correctly.

But when I try to pass the above URL from the applet :

jasperPrint = (JasperPrint)JRLoader.loadObject(new URL("http://localhost:8080/LePere0.1/jasperreport/rpt_Applet?reporttype=PDF"));

then it throws these exceptions :

net.sf.jasperreports.engine.JRException: Error handling object from URL :http://localhost:8080/LePere0.1/jasperreport/rpt_Applet?reporttype=PDF

and

java.io.StreamCorruptedException: invalid stream header

Could anyone tell me why all these happen and the solution(s) for the problem? I highly appreciate all your helps.

Thanks
