Java-Driver: Encountering JAVA-66

[mr.kschan]

i'm encountering the problem as in http://jira.mongodb.org/browse/JAVA-66

What could i do to fix my driver v1.2 copy? checkout the nightly-build
for version 1.2 from git?

Many thx.

The fix went into 1.2 - so if your'e seeing an error that's something else.
Are you sure you're object just isn't too big?
What's the error?

git hash of that .jar is
"9905326f38dcd6ab667b3c6e6a7995b90acfc415" ...

fyi, my binary is a 5.9Mb file upload pdf via http.

Well that's the problem. The max object size is 4mb.
If you want to store a 5.9mb file you should use GridFS

oops... thx for telling this ... so my app should use GridFS for those
collections (or entire db?) that will hv >4mb ...

Is this >4mb information better be placed in the tutorial on
http://www.mongodb.org/display/DOCS/Java+Language+Center =]

thx.

I would only put the files in gridfs.

Its in the general docs - maybe not java section itself.

After reading the gfs-spec from the wiki, i wonder whether i should
store the bin by

GridFSInputFile f = gfs.createFile((byte[]) desc);
f.setContentType("sometype");
f.setFilename("somename");
f.save();

and ...

BasicDBObject o = new BasicDBObject();
o.put("something", something);
o.put("file", f);
coll.insert(o);

Or.. there should be some proper way to do so? Shall i just use o.get
("file") to retrueve that GridFSInputFile ??

thx

I would just store the _id of the grid fs file.
so o.put("file", f.getId() )
