Error when generating columns in jasper report in Java

0

I am developing an application in Java to generate a list in Jasper Report, from a Json file, which can change its structure, that is, change columns and number of them ... that is, it can print a list of clients and the same application a list of articles with their header and report footer data .... After much I have managed to decipher everything and generate the application to the point where using the command "fastReportBuilder.addColumn" .. I am creating the columns .. The code is like that ...

package javaapplication11;
 
import ar.com.fdvs.dj.domain.DynamicReport;
import ar.com.fdvs.dj.domain.builders.FastReportBuilder;
import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.util.Scanner;
 
public class Reportejav {
 
    public static DynamicReport buildReport() throws ClassNotFoundException, FileNotFoundException, IOException {
        FastReportBuilder fastReportBuilder = new FastReportBuilder();
        int contador = 0 ;
         String cadena;
         Scanner scanner = new Scanner(System.in); 
        FileReader f = new FileReader("c:/tools/estructura.Json");
        BufferedReader b = new BufferedReader(f);
        while((cadena = b.readLine())!=null) {
            contador = contador + 1;
            System.out.println(b.readLine());
 
        fastReportBuilder.addColumn(cadena, cadena, String.class.getName(), 50);
           }
        fastReportBuilder.setPrintBackgroundOnOddRows(true).setUseFullPageWidth(true);
          return fastReportBuilder.build();
      }
 
 }

The problem is that compiling it gives me ...:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/collections/list/UnmodifiableList

C:\tools\jasperreports-5.0.1\JavaApplication11\nbproject\build-impl.xml:805: Java returned: 1
BUILD FAILED (total time: 20 

and it no longer follows .. this program is called from another .Java .. but it gives the problem in the line that says.:

return fastReportBuilder.build();

Can someone explain to me what happens or why it gives that error .. I would appreciate it ...

Thank you all!!
