Exception using fileupload on Tomcat5

I'm trying to develop and uploader servlet, and for that I'm using fileupload librery from Apache. I'm running my servlet on: Server Version: Apache Tomcat/5.5.36 Servlet Version: 2.4 JSP Version: 2.0

I'm getting the next exception and I have no idea what do more:

java.lang.NoSuchMethodError: org.apache.commons.fileupload.FileUploadBase.isMultipartContent(Lorg/apache/commons/fileupload/RequestContext;)Z
org.apache.commons.fileupload.servlet.ServletFileUpload.isMultipartContent(ServletFileUpload.java:71)
photoUploader.processRequest(photoUploader.java:48)
photoUploader.doPost(photoUploader.java:87)
javax.servlet.http.HttpServlet.service(HttpServlet.java:647)
javax.servlet.http.HttpServlet.service(HttpServlet.java:729)

It seems to be a trouble with the imports, but I'm not sure.

This is the code I'm using for doing that:

import java.io.File;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.List;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.FileUploadException;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;

public class photoUploader extends HttpServlet {

protected void processRequest(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");

        final String RUTA_LOCAL_APP = getServletContext().getRealPath("/");
        out.println("<!DOCTYPE html>");
            out.println("<html>");
            out.println("<head>");
            out.println("<title>Servlet photoUploader</title>");            
            out.println("</head>");
            out.println("<body>");
            out.println("<h1>Servlet photoUploader at " + request.getContextPath() + "</h1>");
            out.println("<h5>Versiones del Servlet: M->" + getServletContext().getMajorVersion() + 
                        "| m->" + getServletContext().getMinorVersion() + "</h5>");
            out.println("<h5>Adjunta MultipartContent?: " + ServletFileUpload.isMultipartContent(request) + "</h5>");
            }
        catch(Exception e)
        {
            out.println("<h3>Excepción: </h3>" + e.getMessage());
        }
        finally{
            out.println("</body>");
            out.println("</html>");
        }
    }

When I check if isMultipartContent out.println("<h5>Adjunta MultipartContent?: " + ServletFileUpload.isMultipartContent(request) + "</h5>"); is when I get the error.

Im sure I've got *.jar in right place:

            iText.jar
            mysql-connector-java-3.1.13-bin.jar
            poi.jar

Id like to know if:

Any help/idea is welcome, I've tried all solutions proposed on StackOverflow and no one worked for me, so I'm asking again.

Thanks

Finally I got it. I work with Genexus, and inside GXClassR.jar (library used by Genexus) there was another instance of the same *.class (aparently older and out of date). I deleted it and leaved only the new one and it worked.
