Clarification on writing an object to and reading from a database

Question

I am trying to write an object to a relational database, sql server type nvarchar.
Here is my code;
/*create ObjectOutputStream
and ByteArrayOutputStream
ObjectOutputStream formulaOut;
ByteArrayOutputStream out = new ByteArrayOutputStream();
formulaOut = new ObjectOutputStream(out);
/* write my object to the ObjectOutputStream
formulaOut.writeObject(formula);
rq.parameters[0][0] = Integer.toString(formula.getFormulaID());
rq.parameters[1][0] = Integer.toString(formula.getFormulaNumber());
rq.parameters[2][0] = Integer.toString(formula.getInvoiceID());
rq.parameters[3][0] = Integer.toString(formula.getLineItemID());
* place my byteArray into a string array which is a parameter for my stored procedure
rq.parameters[4][0] = out.toString();
out.close();
// the stored procedure complets successfull and I get data in the database
//Here is the code to read the object:
// read a string into an input Byte Array
ByteArrayInputStream in = new ByteArrayInputStream(((String)rowInstance.get(4)).getBytes());
try{
//I get a StreamCorrupted Exception: Caught EOF while reading the stream
objectInput = new ObjectInputStream(in);
singleObject = (LineItemFormula)objectInput.readObject();
catch(Exception e){
System.out.println(this.getClass().getName() + " Class:");
e.printStackTrace();
Any Ideas?

Answer 1

I was able to find a solution: My problem was caused from a loss of data when trying to save it to the databse. I eneded up placing a byte[] into a "|" delimited string and then saving it to the database. I could have probably used Java encoding and decoding but I was loosing time.
Any thoughts on how to save a serialized object to a MSSQL database?
What data type should the database use?
What is the best way to the class to the database without loosing data?
