2005-11-11 05:00

Hi! Sorry for my English.

I create a report with a subreport in Ireport.

I compile and run it and it's ok

After i create a java class to can print master report

but when i compile i receive this error

Error loading object from file : c:test.jasper

Test.jasper is subreport jasper file

My Java code is

public void print_report(ResultSet tmp_res)

{

 

String xmlFileName =

"c:\test.jrxml";

jasperFileName =

"c:\test.jasper";

JRDataSource jrds = new JRResultSetDataSource(

tmp_res);

try {

JasperCompileManager.compileReport(xmlFileName);

// JasperCompileManager.compileReportToFile(xmlFileName,

// jasperFileName);

}

catch (JRException ex1)

{

System.out.println(ex1.getMessage());

}

 

HashMap map = new HashMap();

 

 

net.sf.jasperreports.engine.JasperPrint print = null;

try {

 

 

print = JasperFillManager.fillReport(report, map, jrds);

new JasperPrintManager().printReport(print, true);

 

}

catch (JRException ex) {

System.out.println(ex.getMessage());

}

 

 

}

Can help me?

Thanks

what line throws the exeption?

 

this line:

JasperCompileManager.compileReport(xmlFileName);

 

try this:

JasperReport report; //out of the try

report = JasperCompileManager.compileReport(xmlFileName);
