I am using Mule 3.6 and would like to use the bulk insert option on the Generic Database Configuration to load data into mongodb 3.0.8.
I have entered the URL as:
jdbc:mongo://localhost:27017/test
and have tried a number of different Mongo and JDBC drivers but keep receiving the message "Test connection failed. Error trying to load driver..."
How can I configure the Generic Database Connector in Mule to connect to Mongo?
As already stated in this post, there is no official JDBC driver for MongoDB but one the suggested alternatives is using UnityJDBC.
If you decide to follow the UnityJDBC approach, then:
Download and install the driver by executing the following command:
java -jar UnityJDBC_Trial_Install.jar
Go to the installation folder and copy mongodb_unityjdbc_full.jar to the classpath of your Mule app.
Configure the URL and Driver in the Global Element of your Generic Database component (the values you provided are OK):
URL: jdbc:mongo://<host>:<port>/<database>
Driver Class Name: mongodb.jdbc.MongoDriver
If not, use the MongoDB Connector as suggested by #JoostD.
You need to use the MongoDB connector, it should be included in studio.
Otherwise install it from the Anypoint Exchange:

Also see some example on it:

I have quarkus2.0 application running with mongodb database.
To run my tests, I am depending on devServices option if I am not configuring quarkus.mongodb.connection-string for test profile Quarkus will start mongod docker container for tests.
Issue I have how to pass mongodb connection string options (ex: uuidRepresentation=standard). I am using uuidRepresentation=standard option for application.
Connection-String format as per below:
mongodb://username:password#localhost:27017/dbname?authSource=admin&uuidRepresentation=standard
Have you tried the property 'quarkus.mongodb.devservices.properties' ?
I did not try it but sound like the way to go for your use case. It's avaiable on the 2.1.0 (at least, did not check with 2.0)
Yaml configuration example:
"%dev":
quarkus:
mongodb:
devservices:
properties:
uuidRepresentation: standard
I have a need to dynamically create databases in code via the OrientJS driver. I see an example of how to create an encrypted DB using the Java API but nothing in the JS api/OrientJS.
Sorry, this is not available through remote OrientDB binary protocol, so you cannot do that via JS but also Java API and Console if you use remote protocol.
My application uses both OrientDB and PostgreSQL databases for different purposes.
It seems they were able to coexist before, but today my code stopped working. Upon debugging, it seems that the OrientDB driver is attempting to connect to my PostgreSQL database when I'm expecting the PostgreSQL driver to connect instead.
Here is the sequence of events:
OrientDB connection is made (using OrientGraphFactory.setupPool()), transaction is started.
Connection attempt is made on PostgreSQL database, error occurs when trying to create the Connection object.
Here is the segment of code that creates the PostgreSQL connection:
Class.forName("org.postgresql.Driver");
Connection connection = DriverManager.getConnection(
"jdbc:postgresql://" + [...]);
return connection;
An InvocationTargetException is thrown at the DriverManager.getConnection() line. Here is the stack trace, clearly indicating that the OrientDB driver was the one trying to connect:
Error on opening database 'jdbc:postgresql://[hostname]/[db_name]'

Indeed it seems the JDBC drivers are clashing.
I don't actually need JDBC functionality with OrientDB in this case. However, I can't find the OrientDB JAR that doesn't contain JDBC. The home page lets you download JDBC-all or JDBC-only. Where can I find a JAR with all dependencies bundled into a single JAR, but without JDBC?
This is probably not caused by the drivers themselves but by the DriverManager getting "confused" which driver handles which URL.
You can bypass the DriverManager by asking the driver directly for a connection:
Driver drv = new org.postgresql.Driver();
Properties props = new Properties();
props.put("username", "foo_user");
props.put("password", "database_password");
Connection connection = drv.getConnection("jdbc:postgresql://dbhost/db_name", props);
Unrelated, but: Class.forName("org.postgresql.Driver"); is longer necessary with current Java and driver versions.
I solved the problem here:
https://github.com/orientechnologies/orientdb/commit/8e0f4bed41999cf68ae9de229b3ff6a4260813da
It was a misunderstanding on how the DriverManager registers drivers and then calls the getConnection method.
Solutions.
My suggestion is to not use the orientdb-jdbc-all jar at all. If you don't need to work with orient embedded in your app AND access to it via JDBC it is really too big.
Instead, use your dependency management framework (maven, gradle?) to import orient jars, maybe only the orientdb-client if you need to interact with a remote db, maybe more if you need to embed orient in your app.
If you need to interact to a remote Orient Server via JDBC, use only che orientdb-jdbc. But you need the fixed one, so you should build it from source, or wait for next 2.1.8 release.
If you want to stay with the jdbc fat jar, again you can build it from source right now, or you can wait next hotfix release (2.1.8).
hope this help,
best regards
I am trying to create a jdbc connection to a postgresql database. I would like to use a datasource. In the documentation of postgresql is stated that one should not use their own implementations of the datasource, but use the implementations of org.apache.commons.dbcp instead. The SharedPoolDatasource looks perfect to me.
The jdbc driver must be postgresql. Glassfish v3.1 offers the opportunity to create a jdbc connection pool. I would like to use that one, but do not know how to make the connection between the commons datasource implementation and the jdbc driver. When I fill in the document on the glassfish server that particular field blanks out forcing me to use the postgresql datasource implementation.
Is this impossible to achieve or do I have to enter data manually in config files? So far I did not have any luck nor feedback. Exceptions should appear in the server.log, but the server.log currently does not show anything (it did show exceptions deploying jsf and ejb applications).
Should be possible....
1. Create a new JDBC Connection Pool:
2. Choose your desired Datasource Implementation Class:
You'll have to setup the details for databasename, user and password in the additional properties tab.
3. Create a new JDBC Resource:
How do I add new Database support (MongoDB) in 2.6.3 version of WSO2 Data Service Server.
You can use DSS (2.6.3) with any database type if the database connectivity is exposed via JDBC. In other words, if your preferred database type exposes a JDBC driver/adapter for the users to connect to it via JDBC then you can use DSS to expose your data stored in your data store as a web service. Similarly, if MongoDB too has a JDBC adapter you wouldn't have any (or too many :) ) issues integrating that with DSS. However, there are some exceptions when it comes to exposing flat files such as google spreadsheeets, excel sheets, csv files as DSS uses the relevant client APIs such as Google gdate client API, Apache POI, etc to connect to those datasources and extract data. However, if we consider the general case is you need to have an adapter or a similar mechanism to connect to your datasource via JDBC.
But in the upcoming version of DSS (v3.0.0), it is planned to introduce custom datasource support so you can easily write an adapter to any datasource and use it with DSS.

I am not sure about this, but I suppose that if is not supported by default you can always download the jar library for MongoDB and put it in CARBON_HOME\repository\components\lib and restart. For example for mysql I have the mysql-connector-java-5.1.7-bin.jar in that folder.
Hope this help
