I can't resolv a problem, please help me...

Question

Hi,
The problem is in this code, I try create a Text File with bytearray, but the result doesn't expected :
The problem is on the part of sale.write(body).
I don't received the text correct in the file. The description of the problem is before the code. Please help me, with that problem.
Code:
javax.jms.BytesMessage bytesMessage = (javax.jms.BytesMessage) aMessage;
try
while (true)
int numBytesRead = bytesMessage.readBytes(buffer);
if (numBytesRead == -1)
break;
byte[] tmp = new byte[body.length + numBytesRead];
System.arraycopy(body,0,tmp,0,body.length);
System.arraycopy(buffer,0,tmp,body.length,numBytesRead);
body = tmp;
try
java.io.File file = new java.io.File("paso0409.txt");
java.io.FileOutputStream outputStream = new java.io.FileOutputStream(file);
java.io.DataOutputStream sale = new java.io.DataOutputStream(outputStream);
for(int i = 0; i < body; i++){
sale.write(body);
catch(java.io.IOException jaio)
catch (javax.jms.JMSException jsme)
The file, show me the next text:
qS ��ISO8859-1 � ������EDI_DC40
but the correct text is only ("EDI_DC40"), blank spaces and other text.
How I do, to see only text and not see bytes character ??
Thank's to help me !!

Is the line:
for(int i = 0; i < body; i++){
really supposed to be:
for(int i = 0; i < body.length; i++){
Assuming that's right, one problem I see is the method DataOutputStream.write(byte[] bytes) writes the whole array, but you have a loop that writes the same data body.length times.
On the other hand, it you are going to write a byte array to a file, then you can use the FileOutputStream directly, without using a DataOutputStream.
Your post does not show how the byte array body gets filled. My guess is that's where your problem lies. You might try putting a line in somewhere to display what the contents of the body array is.
System.out.println(new String(body));
should show you the character interpretation of the array of bytes.
