Exception on MongoDB

[Anders Nilsson Plymoth <an...@telhoc.se>]

Hi,

I am just starting using MetaModel, and I am trying to connect to a
MongoDB 3.0.0 DB.

UpdateableDataContext dataContext =
DataContextFactory.createMongoDbDataContext("dude.myserver.com",
27017, "mydb", "mongodb", null);

Output:
Mar 06, 2015 12:05:45 AM com.mongodb.diagnostics.logging.JULLogger log
INFO: Cluster created with settings {hosts=[dude.myserver.com:27017],
mode=SINGLE, requiredClusterType=UNKNOWN,
serverSelectionTimeout='30000 ms', maxWaitQueueSize=50}
Exception in thread "main" java.lang.NoSuchMethodError:
com.mongodb.DB.authenticate(Ljava/lang/String;[C)Z
    at org.apache.metamodel.DataContextFactory.createMongoDbDataContext(DataContextFactory.java:545)
    at org.apache.metamodel.DataContextFactory.createMongoDbDataContext(DataContextFactory.java:578)

The issue seems to be that MetaModel uses the deprecated
DB.authenticate method that was removed in MongoDB 3.0. Looks like
DataContextFactory needs to be rewritten.

Thanks,
Anders

Hi Anders,

Thank you for the notice! Yes we should upgrade the dependency to make sure
we use best practices as prescribed by the MongoDB guys. For a short term
fix I suggest that you use the constructor way of instantiating the
datacontext. That should allow you to do the DB authentication yourself:

DB db = ...;
new MongoDbDataContext(db);

Best regards,
Kasper
