Test data:



<pre>

{

	"database" : "mkyongDB",

	"table" : "hosting",

	"detail" : 

		{

			records : 99,

			index : "vps_index1",

			active : "true"

		}

	}

}

</pre>



BasicDB object:



<pre>

	BasicDBObject document = new BasicDBObject();

	document.put("database", "mkyongDB");

	document.put("table", "hosting");



	BasicDBObject documentDetail = new BasicDBObject();

	documentDetail.put("records", 99);

	documentDetail.put("index", "vps_index1");

	documentDetail.put("active", "true");

	

	document.put("detail", documentDetail);



	collection.insert(document);

</pre>



BasicDBObjectBuilder example:



<pre>

	BasicDBObjectBuilder documentBuilder = BasicDBObjectBuilder.start()

		.add("database", "mkyongDB")

		.add("table", "hosting");

		

	BasicDBObjectBuilder documentBuilderDetail = BasicDBObjectBuilder.start()

	.add("records", 99)

	.add("index", "vps_index1")

	.add("active", "true");

	

	documentBuilder.add("detail", documentBuilderDetail.get());

	

	collection.insert(documentBuilder.get());

</pre>



To insert a Map object into a database:



<pre>

	Map<String, Object> documentMap = new HashMap<String, Object>();

	documentMap.put("database", "mkyongDB");

	documentMap.put("table", "hosting");

		

	Map<String, Object> documentMapDetail = new HashMap<String, Object>();

	documentMapDetail.put("records", 99);

	documentMapDetail.put("index", "vps_index1");

	documentMapDetail.put("active", "true");

	

	documentMap.put("detail", documentMapDetail);

	

	collection.insert(new BasicDBObject(documentMap));

</pre>



To parse JSON in a String in Java:



<pre>

	String json = "{'database' : 'mkyongDB','table' : 'hosting'," +

	  "'detail' : {'records' : 99, 'index' : 'vps_index1', 'active' : 'true'}}}";



	DBObject dbObject = (DBObject)JSON.parse(json);

			

	collection.insert(dbObject);

</pre>
