JSON JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with JSON web services.



Use Arkobi Digital's low-code cloud native platform RunMyProcess's DigitalSuite EnterpriseConnect (DSEC) to connect to JSON.

The CData JDBC Driver for JSON implements JDBC Standards and enables a applications ranging from BI to IDE to connect with JSON. In this article, we describe how to connect to JSON services from Arkobi Digital RunMyProcess's DSEC and connect to JSON in RunMyProcess.

Setting up EnterpriseConnect Agent

Configure the EnterpriseConnect Agent following the EnterpriseConnect page in the RunMyProcess documentation.

Setting up JDBC Adapter

The JDBC Adapter section describes the steps to connect to RDBMS through JDBC. Follow the steps and open the JDBC.config file.

  1. Create a JSON entry for the CData JDBC Driver for JSON, e.g. JSON = { "sqlDriver" : "...", "sqlSource" : "...", "sqlDriverPath" : "..." }
  2. Set the "sqlDriver" field to the Class name for the CData JDBC Driver, e.g.
    cdata.jdbc.json.JSONDriver
  3. Set the "sqlSource" field to a JDBC URL for connecting to JSON, e.g.
    jdbc:json:URI=C:/people.json;DataModel=Relational;

    Built-in Connection String Designer

    For assistance in constructing the JDBC URL, use the connection string designer built into the JSON JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

    java -jar cdata.jdbc.json.jar

    Fill in the connection properties and copy the connection string to the clipboard.

    See the Getting Started chapter in the data provider documentation to authenticate to your data source: The data provider models JSON APIs as bidirectional database tables and JSON files as read-only views (local files, files stored on popular cloud services, and FTP servers). The major authentication schemes are supported, including HTTP Basic, Digest, NTLM, OAuth, and FTP. See the Getting Started chapter in the data provider documentation for authentication guides.

    After setting the URI and providing any authentication values, set DataModel to more closely match the data representation to the structure of your data.

    The DataModel property is the controlling property over how your data is represented into tables and toggles the following basic configurations.

    • Document (default): Model a top-level, document view of your JSON data. The data provider returns nested elements as aggregates of data.
    • FlattenedDocuments: Implicitly join nested documents and their parents into a single table.
    • Relational: Return individual, related tables from hierarchical data. The tables contain a primary key and a foreign key that links to the parent document.

    See the Modeling JSON Data chapter for more information on configuring the relational representation. You will also find the sample data used in the following examples. The data includes entries for people, the cars they own, and various maintenance services performed on those cars.

  4. Set the "sqlDriverPath" field to the name of the CData JDBC Driver JAR file, e.g.
    cdata.jdbc.json.jar

Sample JDBC.config File

#DBAgent Configuration JSON = {"sqlDriver" : "cdata.jdbc.json.JSONDriver", "sqlSource" = "jdbc:json:URI=C:/people.json;DataModel=Relational;","sqlDriverPath" = "cdata.jdbc.json.jar" }

Put the JDBC driver JAR file (cdata.jdbc.json.jar) into the same directory as unified-adapter-[version].jar.

Note: Make sure to put the CData license file (cdata.jdbc.json.lic) into the same directory. Since the license is generated based on the unique identifier of the machine where the product in installed, you will need an offline activation if you want to put the file on another machine.

Starting DigitalSuite EnterpriseConnect Agent

In Windows, start RunMyProcess DigitalSuite EnterpriseConnect Agent in Windows services. To start the application through command line, see Starting the EnterpriseConnect Agent in the RunMyProcess documents.

Starting the JDBC Adapter

Start the JDBC Adapter from runAdapter.bat. Once the Adapter is running, you can access the application through the agent address (e.g. 127.0.0.1:8080). Below is an example executing the command in Windows.

... > java -Djava.util.logging.config.file=./log.properties -cp lib/* org.runmyprocess.sec2.AdapterHandler : 2021-06-09 14:37:58|INFO|correlationId=|Searching for config file... 2021-06-09 14:37:58|INFO|correlationId=|Adapter Handler started with [JDBC] configuration 2021-06-09 14:37:59|INFO|correlationId=|agent address: 127.0.0.1:8080 2021-06-09 14:38:00.251:INFO::ConnectionThread: Logging initialized @1820ms to org.eclipse.jetty.util.log.StdErrLog 2021-06-09 14:38:00|INFO|correlationId=|onConnect() websocket connection between Agent and Adapter established

Once the DigitalSuite EnterpriseConnect Agent and JDBC Adapter are running, access http://localhost:(specified-port-number)/ through your browser to open the page shown below.

Check the availability of the JDBC Adapter using tools such as Postman or cURL. Here, we use Postman to send the HTTP POST request.

Configure the RequestHeader as follows:

Content-Type application/json

Configure the RequestBody as follows:

{ "protocol":"JDBC", "data":{ "DBType":"JSON", "sqlUsername":"", "sqlPassword":"", "sqlStatement":"SELECT * FROM people" } }

If the JDBC.config file contains credential information, sqlUsername and sqlPassword can be left empty. If you are not sure of the table name, you can retrieve the list of tables using the request SELECT * FROM sys_tables

The request is successful if the Status is 200 and the Body contains JSON services in JSON format.

Connect to JSON through DSEC Agent in DigitalSuite Studio

Create a DigitalSuite Studio project and then create a Provider in the project.

  • URL: The URL for accessing JDBC Agent (e.g. http:localhost:8080/)
  • Authentication Scheme: Login/password
  • Login: The value from agent.user in the application.properties file
  • Password: agent.password in the application.properties file
  • Secured: Checked
  • Use DigitalSuite EnterpriseConnect: Checked
  • With domain: The value from agent.domain in application.properties file

Next, create a Connector in the Provider.

  • Connector URL: Leave this empty
  • Architecture: REST/XML-RPC
  • Method: POST
  • Result format: JSON
  • Accept media type: application/json
  • Character set: Automatic
  • Content: Same as the Request body used in the JDBC Adapter
  • Content type: application/json

The JSON data we used as the Request body in JDBC Adapter:

{ "protocol":"JDBC", "data":{ "DBType":"JSON", "sqlUsername":"", "sqlPassword":"", "sqlStatement":"SELECT * FROM people" } }

Open Launch Test to perform the test. The test is successful if JSON services is shown in Result on the right pane.

Now you can use JSON services in RunMyProcess DigitalSuite Studio through DSEC.
