jasper report problem

[realosso]

Hi,
I've created a report in jasperReport. I want to view and print this report from my java code. But it gives exception. Code as follows, where there are errors?

public void runReport() {
      try{
          st = connectDB();
          res = st.executeQuery("SELECT * FROM Kayitlar");

          JRResultSetDataSource jrRS = new JRResultSetDataSource( res );
          Map parameters = new HashMap();

          (Line 158) JasperReport jasperReport = JasperCompileManager.compileReport("report1.jrxml" );
          JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, jrRS);
          JasperExportManager.exportReportToPdfFile(jasperPrint, "report1.pdf");

          closeDB();
     }

     catch(Exception e) { 
          Logger.getLogger(ProgramRaporlama.class.getName()) .log(Level.SEVERE, null, e);
     }
}

Exception occurred during event dispatching:
java.lang.NoClassDefFoundError: org/apache/commons/digester/Digester
at net.sf.jasperreports.engine.JasperCompileManager.c ompileReport(JasperCompileManager.java:146)
at programkayit.ProgramRaporlama.runReport(ProgramRap orlama.java:158)

Check on tomcat lib installation folder that commons-digester.jar is exist or not.

I did not install tomcat. I did not understand why it should, sorry I'm using for the first time jasperrepots.

If you don't install then you've to added relevant libraries into your classpath. VM cannot find required libraries on your system, that's what compiler says.
