    Default MongoDB (java driver) problem

    Hello, I am trying to record a specific entry into mongo db ( it`s running with the daemon ), so I`ve followed the simple steps:
    Java Code:
    public void run() {
    	try {
    		Mongo mg = new Mongo();
    		DB db = mg.getDB("testdb");
    				new BasicDBObject());
    		DBCollection tab = db.getCollection("workers");
    	        BasicDBObject doc = new BasicDBObject();
    		BasicDBObject[] workers = 
    					new BasicDBObject[store.getEmps().size()];
    				for (int i=0; i < (store.getEmps().size()); i++) {
    					workers[i].put("name", (store.getEmps().get(i)).getName());
    					workers[i].put("date", new Date());
    		doc.put("workers", workers);
    		BasicDBObject searchq = new BasicDBObject();
    		searchq.put("workers", "name");
    		DBCursor cursor = tab.find(searchq);
    		while ( cursor.hasNext() ) {
             } catch (UnknownHostException ukhe1) {
    When I compile it, it`s OK, but when I run the jar it gaves me over 50 exceptins mainly from the swing... Here is some of them:

    Default Re: MongoDB (java driver) problem

    I`ve spotted it, apparently bad defined Manifest.
