I have a Grails 2.4.4 app that is using MongoLab as it's database. I was previously connecting to the db using a mongo plugin for GORM (see plugin here). That has been less then a good experience, so I am in the process of switching over to Morpia and away from GORM for mongodb.

I currently have morphia library version 1.0.1 as a compile time dependency in the project. I have created a user in Mongolab with username: username, and password: pass (not actual creds...)

I am attempting the connect to the database using MongoClient. I have been looking at the documentation (documentation here) and I have also referenced this question but it is using the old way of connecting.

Here is my error, even though I don't see a reason why this error is being thrown because the format of my string appears to be correct:

Here is a code snipplet that I have in resources.groovy where I am attempting the register the MongoClient, Morphia, and my datastore as spring beans.

beans = {

String databaseUrl = "mongodb://username:pass@ds053251.mongolab.com:12345/trendapp" //fake port
String databaseName = "trendapp"

mongoClient(MongoClient, databaseUrl)
morphia(Morphia)

datastore(Datastore, ref('mongoClient'), databaseName) { bean ->
    bean.factoryBean = 'morphia'
    bean.factoryMethod = 'createDatastore'
}
}

Any help is appreciated, thank you.

You should provide the MongoClient with a MongoClientURI

MongoClientURI mongoClientURI = new MongoClientURI("connection string");
MongoClient mongoClient = new MongoClient(mongoClientURI);

So I did not figure out why this error was being thrown, but I was able to connect to my database by using a different constructor of the MongoClient, specifically the one that takes (ServerAddress, List<MongoCredential>).
