Problem updating BLOB with Hibernate?
- by JohnSmith
hi, i am having problem updating a blob with hibernate. (i am using Hiberante 3.3.1-GA)
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) {
}
}
my hibernate mapping for the blob looks like
<property name="logoBinaryBlob" column="LOGO_BINARY" type="blob" />
