I am trying to use the java mongo driver with Play!. So I read though: http://www.playframework.org/documentation/2.0.2/SBTDependencies http://www.mongodb.org/display/DOCS/Java+Tutorial I added the buildpath in eclipse. But play can't find the dependency. So there is an example on the playframework homepage but I still can't figure it out. val appDependencies = Seq( "org.scala-tools" %% "scala-stm" % "0.3", "org.apache.derby" % "derby" % "10.4.1.3" % "test" ) Why are der two% signs?

There is an option i see about mongoClientOptions but i dont see options to set connection pool You can build your own MongoClient instance using the MongoClientOptions.Builder . MongoClientOptions.Builder builder = new MongoClientOptions.Builder(); MongoClientOptions options = builder.connectionsPerHost(10).build(); MongoClient client = new MongoClient(listOfServers, options); As another option(and

After reviewing this page , specifically this query db.scores.find( { results: { $elemMatch: { $gte: 80, $lt: 85 } } } ) I used the following imports import static com.mongodb.client.model.Filters.and; import static com.mongodb.client.model.Filters.elemMatch; import static com.mongodb.client.model.Filters.eq; import static com.mongodb.client.model.Projections.excludeId; import static com.mongodb.client.model.Projections.fields; import static com.mongodb.client.model.Projections.include; And came up with the following code to perform a similar operation ( ARRAY_FIELD_NAME = "myArray" )

I have a JUnit rule called as MongoRule looks like public class MongoRule extends ExternalResource { private static final Logger LOGGER = LoggerFactory.getLogger(MongoRule.class); private final MongoService mongoService; public MongoRule() throws UnknownHostException { mongoService = new MongoService(getConfiguredHost(), getConfiguredPort(), getConfiguredDatabase()); } @Override protected void before() throws Throwable { LOGGER.info(" Setting up Mongo Database - " + getConfiguredDatabase()); } @Override protected void after() { LOGGER.info("Shutting down the Mongo Database - " +
