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?
