Storing image to rms as bytes

Question

hi, here imtrying to save image into rms and load the same from rms but i couldnt able to display the code
size of byte im getting is 1
import javax.microedition.rms.*;
import javax.microedition.midlet.MIDlet;
import javax.microedition.lcdui.*;
import java.io.*;
public class RMSImage extends MIDlet
{Form frm=null;
  private Display display;
RecordStore rs;
public RMSImage(){
                    rs=null;
                    //      InputStream is=null;
                    display = Display.getDisplay(this);
frm = new Form("Imageshow");
public void startApp(){
try{
          rs=RecordStore.openRecordStore("imagefile",true);
          System.out.println("record store created");
     catch(RecordStoreException r){r.printStackTrace();}
save();
     display.setCurrent(frm);
public void save(){
// System.out.println(imgdata);
try{
ByteArrayOutputStream baos = new ByteArrayOutputStream();
DataOutputStream dos = new DataOutputStream(baos);
byte data[]= null;
          try{
                    System.out.println("hi");
               DataInputStream dis = new DataInputStream(this.getClass().getResourceAsStream("/Duke.png"));
     System.out.println("check for image length");
     /* for(int j=0;j<3524;j++){ System.out.println("loop entering");data[j] = dis.readByte();System.out.println(data.length);
          System.out.println("datalength"+data.length);
          for (int i = 0; i < data.length; i++)
          dos.writeByte(dis.readByte());
          catch(Exception e){System.out.println(e);}
//System.out.println(imgdata);
int x=baos.toByteArray().length;
int r=rs.addRecord(baos.toByteArray(),0,baos.toByteArray().length);
System.out.println("length is"+x);
load(r);
catch(RecordStoreNotFoundException rsnfe){}
catch(RecordStoreException rse){}
catch(Exception ioe){}
System.out.println("sucess");
public void load(int i){
try{
byte data[]=rs.getRecord(i);
System.out.println(data.length);
Image.createImage(data,0,data.length);
}catch(RecordStoreException e){}
public void pauseApp(){}
public void destroyApp(boolean flag){
//System.out.println(save());
}

Answer 1

i kept that in for loop
even then i cudnt get the image n length same as i mentioned in the loop
response------>
Project "saveimage" loaded
Project settings saved
Building "saveimage"
Build complete
Running with storage root DefaultColorPhone
record store created
hi
check for image length
java.io.EOFException
length is2869
2869
sucess
Execution completed.
955248 bytecodes executed
28 thread switches
742 classes in the system (including system classes)
3980 dynamic objects allocated (134324 bytes)
2 garbage collections (90936 bytes collected)
But actual length is 3524 but length displayed is another
more over if i need multiple images to store what shal i do then
