What does the blob represent, an image?

ResultSet rs = s.executeQuery("SELECT image FROM myImageTable");
if (rs.next())
    Blob blob = rs.getBlob("image ");
    long n = blob.length();
    byte[] bytes = blob.getBytes(1, n);
    Image i = Toolkit.getDefaultToolkit().createImage(bytes);

Although you will need to use a callable statement for the stored proc:

CallableStatement stmt =  con.prepareCall( "{call spu_get_image()}");
ResultSet rs = stmt.executeQuery();

>>how to get a blob from stored procedure

Sorry but what do you mean. You write a stored procedure that performs a select statement that returns a resultset. In the resultset is a blob which you then use as in my first example.
