Hi.
My system is writen on php and java.
I started testing php and java drivers to communicate with GridFs.
I can store and get files with php, and so with java, but
when I store a file with php in GridFs and then want to get and write it to fs with java it fails:

java.lang.ClassCastException: org.bson.types.Binary cannot be cast to [B
at com.mongodb.gridfs.GridFSDBFile.getChunk(GridFSDBFile.java:89)
at com.mongodb.gridfs.GridFSDBFile.writeTo(GridFSDBFile.java:75)

but when with java and then with php, everything ok.

sample code i am using:

PHP WRITE CODE

$m = new Mongo();
$fs = $m->test->getGridFs();
echo $fs->storeFile("J:
1.avi", array('filename' => 'filename1'), array('safe' => true));

JAVA READ CODE

GridFS myFS;
try {
myFS = new GridFS(new Mongo().getDB("test"));
GridFSDBFile f = myFS.findOne("filename1");
if(f!=null)

{ f.writeTo("J:\\res.txt"); System.out.println("true"); }

else

{ System.out.println("false"); }

} catch (Exception ex)

{ Logger.getLogger(Ufs.class.getName()).log(Level.SEVERE, null, ex); }

ps

I danced a lot with this code, modified parameters, changed ids, php and java drivers on older versions. Nothing helped.
And java gets file by id fine, but when saving getting exception.

What I am doing wrong ?

Thanks.
