invalid stream header

[Parameswaran Thangavel]

Hi all
I am getting the below error when i tried to read the content form the byte[].
I am gettting the byte array from the services method (backend).

ByteArrayInputStream bos = null;
        ObjectInputStream oos = null;
        Object obj = null;
        try{
        System.out.println("b4 byte arra input stream");
            bos = new ByteArrayInputStream(bArr);
            System.out.println("b4 object input stream");
            oos=new ObjectInputStream(bos); //Getting the error here
            //obj = oos.readObject();
        } 
        /*catch(IOException e){
     throw e;
        } catch(ClassNotFoundException e){
            throw e;
        }*/
        finally{
            try{
                if (bos != null ) bos.close();
                if(oos != null) oos.close();
            }
            catch (java.io.IOException e){
            throw e;
            }
        }
        
        return obj;

stacktrace:

Any idea??

ObjectInputStream is used to convert the set of bytes into object. It cannot convert any arbitrary set of bytes into an object. It has its own format. Usually you would use ObjectInputStream on stream which is created by ObjectOutputStream. So here the stream you are using (bArr) not in a format expected by ObjectInputStream.
