How to store HTML data in MongoDB?

问题

I'm trying to crawl the web and store HTML data on MongoDB using Java. Unfortunetely while storing data, MongoDB drivers nulling the data and stores empty field for HTML data.

When I get the first 500 chars of HTML data, I can store/upsert it without a problem so I think something in HTML (or Javascript in it) corrupts the command sent to MongoDB and MongoDB stores empty data instead of HTML. (EDIT: Also I've tried with 40.000 and 50.000 chars and 40.000 was OK but 50.000 char data didn't show up on MongoDB) Should I use something else for storing HTML/JavaScript data?

Here is my code snippet

BasicDBObject savedDoc = new BasicDBObject();
savedDoc.put("url_ID", objURL.get("_id"));
savedDoc.put("cnt", content); //Content field
savedDoc.put("st", 0);
collection.update(new BasicDBObject().append("url_ID", objURL.get("_id")), savedDoc, true, false);
