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

I am trying to see whether MarkLogic Java API can be used to create a content database and REST Server?
I went through te Java API but I dont see any reference.
Is it possible to create a REST Server through MarkLogic Java API?
I appreciate any links or pointers regarding this.
No, that's beyond the scope of the Java Client API. The Java Client API must connect to a REST Server after it's already created. You can, however, use the /rest-apis service on port 8002 via your favorite generic REST client API for Java. To see an example of how to do this with Apache HttpClient, see Bootstrapper.java. You can use it directly like the unit tests setup util TestServerBootstrapper.java does with this code:
Bootstrapper.main(new String[] {
"-configuser", username,
"-configpassword", password,
"-confighost", host,
"-restserver", "java-unittest",
"-restport", ""+port,
"-restdb", "java-unittest"});
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 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.
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:
I am working on building a web service from scratch with JDBC for postgreSQL. thing is that the operations given in the wsdl file do not show the corresponding database relation (Schema was provided by the client). i.e. for a message like
message name="loginRequest">
part name="in0" type="xsd:string"/>
part name="in1" type="xsd:string"/>
/message>
I cannot find out the corresponding column or what the parameters map on to.
Any solution?
P.S.I had to remove "<"
JDBC is an interface for databases. It can be used for both WebService server and client, but it cannot be used to parse WebService queries etc. You will have to use other library/technology like axis2.
In axis2 there is wsdl2java utility which can create server or client code "skeleton". In those sources you can use JDBC libraries to make database queries.
