Blob Tutorial

[ccharpentier]

I try to use the blob tutorial and modify it.

I want to test with fileInput
in the bean to create from file, it 's working

public long create()
 {
 BlobEntity blob = new BlobEntity();

 File file = new File("D:\\data.dat");
 int fileLength = (int) file.length();
try {
 FileInputStream fileinp = new FileInputStream(file);

 blob.setBlobby(Hibernate.createBlob(fileinp));
 }
 catch (IOException e)
 {
 throw new RuntimeException(e);
 }
}

but Ican not manage to get my file from the blob

I try lot of thing, I get some Serialisation error
here the code to find blob

public InputStream findBlob(long id) throws Exception
 {
 BlobEntity blob = manager.find(BlobEntity.class, id);
 ObjectInputStream ois = new ObjectInputStream(blob.getBlobby().getBinaryStream());
 return (InputStream) ois.readObject();
 }

how I can get the file stream?
