How to store image into postgres database using hibernate

I want to store image into database using hibernate and Java. I am using postgres database

I tried bytea data type to store image and byte[] data type in hibernate pojo.

I used the following code,

CREATE TABLE photo
(
  "photo_name" bytea
)
WITH (OIDS=FALSE);
ALTER TABLE photo OWNER TO postgres;

Hibernate Pojo

public class PhotoEntity {

byte[] name;

public byte[] getName() {
    return name;
}

public void setName(byte[] name) {
    this.name = name;
}

}

but it gives error at time of mapping.
please give me any reference to do this.

If you are using Hibernate via JPA2, you may need the @Lob annotation, though I'm not sure if that's for oid or bytea fields. See:

proper hibernate annotation for byte[]

There's also a Hibernate dev blog post that's quite informative.

If you're using Hibernate via XML mappings or its own annotations dialect, please show your exact code and error message(s).
