google app engine and mongodb

Question

I'm using Java and MongoDB on google app engine but I cant find any reference on how to connect to MongoDB with Java.

I've tried with the following:

Maven:

    <dependency>
        <groupId>org.mongodb</groupId>
        <artifactId>mongo-java-driver</artifactId>
        <version>2.6.3</version>
    </dependency>

Java:

String serverName = ""; //provided external and internal ip addresses as well as name of mongoDB instance,
Mongo mongo = new Mongo(serverName); //com.addsapp.dao.MongoDB.initDB1(MongoDB.java:39)

And got the following result:

Uncaught exception from servlet
    java.lang.ExceptionInInitializerError
    at com.mongodb.Bytes.<clinit>(Bytes.java:215)
    at com.mongodb.MongoOptions.reset(MongoOptions.java:32)
    at com.mongodb.MongoOptions.<init>(MongoOptions.java:28)
    at com.mongodb.Mongo.<init>(Mongo.java:175)
    at com.mongodb.Mongo.<init>(Mongo.java:140)
    at com.addsapp.dao.MongoDB.initDB1(MongoDB.java:39)
    ...

Does anyone have a good Java reference on how to do this? Couldn't find anything on tzhe netz.

Thanks.

You can't. You have to use the storage options given, like the datastore. You could connect via a web interface of course to an external instance, but I don't think that's what you are asking.

Take a look at compute http://googlecloudplatform.blogspot.co.uk/2014/06/running-mongodb-on-google-compute-engine.html
