hi, i am having problem updating a blob with hibernate.

my model have these getters/setters for hibernate, i.e. internally i deal with byte[] so any getter/setter convert the byte[] to blog.

I can create an initial object without problem, but if I try to change the content of the blob, the database column is not updated. I do not get any error message, everything looks fine, except that the database is not updated.

/** do not use, for hibernate only */
public Blob getLogoBinaryBlob() {
    if(logoBinary == null){
        return null;
    }
    return Hibernate.createBlob(logoBinary);
}

/** do not use, for hibernate only */
public void setLogoBinaryBlob(Blob logoBinaryBlob) {

    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    try {
        logoBinary = toByteArrayImpl(logoBinaryBlob, baos);
    } catch (Exception e) {
    }
  }
