I think BSF does not support generics (<...>) you need to stick to Java 1.4
syntax.
{{MongoCollection collection = database.getCollection("customer");}}

> I'm trying to access a MongoDB collection from a java code to be 'eval' by
> BSF.
> I tried configure the MongoDB connection in both ways coding the driver
> connection and following the tutorial
> [https://mongodb.github.io/mongo-java-driver/3.10/driver/tutorials/jndi/] ,
> but in both cases the same error.
> Below the code to be executed by BSF:
>
> {code:java}
> import javax.naming.InitialContext;
> import com.mongodb.MongoClient;
> import com.mongodb.client.MongoDatabase;
> import com.mongodb.client.MongoCollection;
> import org.bson.Document;
> InitialContext cxt = new InitialContext();
> if ( cxt == null ) {
> throw new Exception("Uh oh -- no context!");
> }
> MongoClient ds = (MongoClient) cxt.lookup(
> "java:/comp/env/mongodb/MongoClient" );
> if ( ds == null ) {
> throw new Exception("Data source not found!");
> }
> MongoDatabase database = ds.getDatabase("ssp");
> //MongoCollection<Document> collection = database.getCollection("customer");
> {code}
>
> The code above runs fine, but If I uncomment the last line
> *MongoCollection<Document> collection = database.getCollection("customer")* ,
> the BSF throw a exception. See the attached *exception.txt* file.
