EnterpriseDB JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with EnterpriseDB.



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

The CData JDBC Driver for EnterpriseDB implements JDBC Standards and enables a applications ranging from BI to IDE to connect with EnterpriseDB. In this article, we describe how to connect to EnterpriseDB data from Arkobi Digital RunMyProcess's DSEC and connect to EnterpriseDB 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 EnterpriseDB, e.g. EnterpriseDB = { "sqlDriver" : "...", "sqlSource" : "...", "sqlDriverPath" : "..." }
  2. Set the "sqlDriver" field to the Class name for the CData JDBC Driver, e.g.
    cdata.jdbc.enterprisedb.EnterpriseDBDriver
  3. Set the "sqlSource" field to a JDBC URL for connecting to EnterpriseDB, e.g.
    jdbc:enterprisedb:User=postgres;Password=admin;Database=postgres;Server=127.0.0.1;Port=5444

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.enterprisedb.jar

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

    The following connection properties are required in order to connect to data.

    • Server: The host name or IP of the server hosting the EnterpriseDB database.
    • Port: The port of the server hosting the EnterpriseDB database.

    You can also optionally set the following:

    • Database: The default database to connect to when connecting to the EnterpriseDB Server. If this is not set, the user's default database will be used.

    Connect Using Standard Authentication

    To authenticate using standard authentication, set the following:

    • User: The user which will be used to authenticate with the EnterpriseDB server.
    • Password: The password which will be used to authenticate with the EnterpriseDB server.

    Connect Using SSL Authentication

    You can leverage SSL authentication to connect to EnterpriseDB data via a secure session. Configure the following connection properties to connect to data:

    • SSLClientCert: Set this to the name of the certificate store for the client certificate. Used in the case of 2-way SSL, where truststore and keystore are kept on both the client and server machines.
    • SSLClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
    • SSLClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
    • SSLClientCertType: The certificate type of the client store.
    • SSLServerCert: The certificate to be accepted from the server.
  4. Set the "sqlDriverPath" field to the name of the CData JDBC Driver JAR file, e.g.
    cdata.jdbc.enterprisedb.jar

Sample JDBC.config File

#DBAgent Configuration EnterpriseDB = {"sqlDriver" : "cdata.jdbc.enterprisedb.EnterpriseDBDriver", "sqlSource" = "jdbc:enterprisedb:User=postgres;Password=admin;Database=postgres;Server=127.0.0.1;Port=5444","sqlDriverPath" = "cdata.jdbc.enterprisedb.jar" }

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

Note: Make sure to put the CData license file (cdata.jdbc.enterprisedb.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":"EnterpriseDB", "sqlUsername":"", "sqlPassword":"", "sqlStatement":"SELECT * FROM Orders" } }

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 EnterpriseDB data in JSON format.

Connect to EnterpriseDB 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":"EnterpriseDB", "sqlUsername":"", "sqlPassword":"", "sqlStatement":"SELECT * FROM Orders" } }

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

Now you can use EnterpriseDB data in RunMyProcess DigitalSuite Studio through DSEC.
