You could use a JSON intrepretter, like this one implemented in ANTLR, and output nested BasicDBObject's. The only remaining piece is parsing the db.collectionname.find(...), which should be relatively straightforward. Instead of ANTLR, you can also find one of probably many Java JSON parsers and instantiate the BasicDBObject's yourself.

Mr.slee Actually i dont know whether you have mis-understood the question? Actually i have to simulate "pgsql databasename -f file.sql" in mongoDB or just read the raw mongoDb queries from a .txt/.js file and execute them via the javacode.if the above solution is also doing the same please explain in detail or just guide me with any other simple tutorials its above my head.
