Hi,

I'm not sure if this the correct way to store files in DB. Why don't you just take the bytes with the correct encoding, save them in the DB. When you want to extract the String from the DB, you could read the bytes in byte array, write them in file or create a string with the proper encoding.

You could encode String as a BigInteger but this is highly ineffective.

Hi Sunil,

I got your problem, you need to convert the <b>String</b> to a <b>Document</b> object. Use the following code to do it,

String str  = "<xml></xml>"; 
InputStream is = new StringBufferInputStream(str);
DocumentBuilderFactory dBF = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = dBF.newDocumentBuilder();
Document doc = builder.parse(is); 

I'm sure that'll help you.

Hi Sumit,

Can you elaborate on the method (post some code snippet as well) that you used in the conversion. That will help me in solving your problem.

Hi Guru,

This is the code :

String d = writtenDocument.toString();

byte[] bytes = d.getBytes("US-ASCII");

BigInteger bi = new BigInteger(bytes);

String s = bi.toString(16);

if (s.length() % 2 != 0) {

// Pad with 0

s = "0" + s;

}

Here writtenDocument is org.w3c.dom.Document.

Thanx & Regards

Sumit
