How to call a javabean with more argumets?

Question

I've create a javabean with more arguments,i've used fbean.add_arg:
arglist := FBean.Create_Arglist;
FBean.add_arg(arglist,'c:\dev10\esdir.fmb');
FBean.add_arg(arglist,wdata);
FBean.add_arg(arglist,wtime);
wprova:=FBean.invoke_char('BEAN_IMAGE',1,'getDATA',arglist);
but the javabean isn't invoked, where is my error?
the javabean's code is:
package oracle.forms.fd;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.Toolkit;
import java.io.*;
import java.net.URL;
import java.sql.*;
import java.lang.Long;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import oracle.forms.properties.ID;
import oracle.forms.ui.VBean;
public class LeggiDir extends VBean
private URL url;
private Image img;
public LeggiDir()
super();
System.out.println("prova");
public void paint(Graphics g) {
// draw the image
g.drawImage(img, 0, 0, this);
public void DisplayImage( String sFileName )
// load image file
System.out.println("prova 2");
img = getImage(sFileName);
repaint() ;
public static Image getImage(String imageURL)
// URL imageURL = null;
boolean loadSuccess = false;
Image img = null ;
//JAR
// imageURL = imageName;
if (imageURL != null)
try
img = Toolkit.getDefaultToolkit().getImage(new java.net.URL(imageURL));
loadSuccess = true;
System.out.println("prova 3");
return img ;
catch (Exception ilex)
System.out.println("Error loading image from JAR: " + ilex.toString());
else
System.out.println("Unable to find " + imageURL + " in JAR");
if (loadSuccess == false)
System.out.println("Error image " + imageURL + " could not be located");
return img ;
public static String getList(String directory)
String result = null;
String element = "";
File path = new File( directory );
File files[] = path.listFiles() ;
String[] list = path.list();
File p ;
long lSize ;
SimpleDateFormat data_formato = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
for(int i = 0; i < list.length; i++)
p = files[i] ;
lSize = p.lastModified();
// System.out.println(data.toString());
element = element + data_formato.format(new Date(p.lastModified()))+' '+ list[i] + ' '+ '|';
return element;
public static String getFile(String filename)
String result = null;
String element = "";
File p = new File( filename );
long lSize ;
SimpleDateFormat data_formato = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
lSize = p.lastModified();
System.out.println(lSize);
element = data_formato.format(new Date(p.lastModified()));
return element;
public static String getData(String filename,String datafile,String orafile)
System.out.println("entrato");
String element = "";
String data_costr = "";
File p = new File( filename );
SimpleDateFormat data_formato = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
data_costr = datafile + ' '+orafile;
System.out.println(data_costr);
Date date = null;
boolean success = true;
try
date = data_formato.parse(data_costr);
long datacorr = date.getTime();
success = p.setLastModified(datacorr);
} catch (ParseException e) {
success = false;
if (success)
element = data_formato.format(new Date(p.lastModified()));
return element;
else
element = "data errata";
return element;

Hello,
Java is case sensitive. you call a getDATA function from Forms, but there is a getData() in the bean.
