NoSuchMethodException (JRBaseFiller.java:424)

2002-08-16 11:44

Trying to load, compile and run an XML file we created. Here's the code:

 

FileOutputStream outStream = new FileOutputStream("C:/Program Files/IBM/Application Developer/centurn_exp.pdf");

 

// connection = DataAccess.getConnection("billing");

String driverName = "oracle.jdbc.driver.OracleDriver";

String url = "jdbc:oracle:oci8:@STARDEV.WORLD";

String userName = "conversion";

String password = "conv2java";

 

connection = DBConnection.getConnection(driverName, url, userName, password);

 

Map parameters = new HashMap();

parameters.put("fromDate", "'07-01-2001'");

parameters.put("toDate", "'06-30-2002'");

parameters.put("svcNumString", "'07','16'");

 

JasperReport jr = JasperManager.compileReport(getJasperDesign());

 

JasperPrint jp = JasperManager.fillReport(jr, parameters, connection);

 

if (jp.getPages().size() < 1) {

fail("Report Empty");

}

 

byte[] reportAsPdf = JasperPrintManager.printReportToPdf(jp);

 

outStream.write(reportAsPdf);

 

outStream.close();

 

 

And here's the stack trace:

NOTE: We have checked and rechecked that we have tools.jar, xerces.jar, etc., in the classpath. We are trying it with jdk1.3.1_04. Running the same XML file within the JasperEdit application seems to work just fine (which is almost the exact same code we are trying to use).

 

Thanks in advance!!!

Found the problem.

 

When running JUnit, the ClassLoader is screwing things up. Not sure why...guess we'll have to figure out a different way to test it. :)
