JasperReports and RMI

2005-06-16 16:28

What I'm trying to do is have my server program generate the JasperPrint object and then return it to my client program which will display the report. The problem occurs on the server side when I try to fill the report with data. No exception is thrown. The program just hangs at the line JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, conn);

 

Here is a sample of the rest of the code running on my server.

 

 

public JasperPrint getReport()

{

try

{

URL fileURL = new URL("http://.../TestReport2.jasper");

Map parameters = new HashMap();

JRLoader jrLoader = new JRLoader();

JasperReport jasperReport = (JasperReport)jrLoader.loadObject(fileURL);

Class.forName(driver).newInstance();

Connection conn = DriverManager.getConnection(url, login, password);

JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, conn);

return jasperPrint;

}

catch(Exception ex)

{

System.out.println(ex);

return null;

}

}

 

Any help will be greatly appreciated. Thank you.

Well, I'd use "ex.printStackTrace" or throw the exception. I don't believe that there isn't ANY exception at all. So just throw it or use the printStackTrace, that should appear in your Server.log of (e.g. JBoss)

Wouldn't the try and catch block display any exception? It looks like processing just stops once it reaches the JasperFillManager.fillReport(..) command.
