Connect to JD Edwards Data from PowerBuilder via JDBC

The CData JDBC driver for JD Edwards is a standards-based control that can be used from any platform or development technology that supports JDBC, including PowerBuilder. This article shows how to use the CData JDBC Driver for JD Edwards in PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData JDBC Driver for JD Edwards to retrieve data.

Connect to JD Edwards Data from PowerBuilder

Follow the steps below to use the Database Painter tool to create a database profile based on an JDBC URL for JD Edwards. You can use a database profile to save connection properties. In the Database Painter, you can graphically manipulate data as well as execute SQL queries.

1. Add the driver JAR to the PowerBuilder classpath. Set the CLASSPATH system environment variable to the path to the driver JAR, located in the lib subfolder of the installation directory.

   Note: If you are using PowerBuilder Classic, you can also add the path to the driver JAR by clicking Tools -> System Options -> Java.

2. Click Tools -> Database Painter.
3. Right-click the JDBC node and click New Profile.
4. In the Database Profile Setup dialog, enter the following:
   • Profile Name: Enter a user-friendly name for the profile.
   • Driver Name: Enter the class name of the driver, cdata.jdbc.jdedwards.JDEdwardsDriver
   • URL: Enter the JDBC URL.

     The driver connects to JD Edwards through your Application Interface Services (AIS) Server. Set the following connection properties:

     • URL: The base HTTPS URL of your AIS Server (e.g., https://jde-ais.example.com:8300).
     • User: Your JD Edwards username.
     • Password: Your JD Edwards password.
     • Environment (optional): The JD Edwards environment to use (e.g., PD920 for production or DV920 for development). If not specified, the AIS Server's default environment is used.
     • Role (optional): The JD Edwards role for the session. If not specified, the AIS Server's default role is used.
     • DeviceName (optional): An identifier for the connecting device or application, used for auditing and logging on the AIS Server.
     • Jasserver (optional): The specific Java Application Server (JAS) instance to route requests through, useful in clustered environments.

     Choosing Which Data Is Exposed

     JD Edwards organizes tables and business views by System Code, and the driver exposes each System Code as its own schema. Use these properties to control which schemas are available:

     • DataModel: One or more ERP modules (comma-separated) whose System Codes are exposed as schemas, or All to expose every System Code in the connected instance. Defaults to FinancialManagement.
     • SystemCodes: A comma-separated list of additional System Codes to expose alongside those from DataModel (e.g., 42,43).

     When you connect, the driver sends your credentials to the AIS Server to obtain a session token and caches it. The driver requests a new token automatically before the session expires.

     Built-in Connection String Designer

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

     
     java -jar cdata.jdbc.jdedwards.jar
     

     Fill in the connection properties and copy the connection string to the clipboard. A typical JDBC URL is below:

     jdbc:jdedwards:URL=https://your-jde-environment-app.example.com;User=admin;Password=myPassword;

   
5. To view and modify a table, right-click a table and then click Edit Data -> Grid.

Using JD Edwards Data with PowerBuilder Controls

You can use standard PowerBuilder objects to connect to JDBC data sources and execute queries. The following example shows how to retrieve JD Edwards data into a DataWindow. You can add the following code to the open method:

SQLCA.DBMS = "JDBC"
SQLCA.AutoCommit = False
SQLCA.DBParm = "Driver='cdata.jdbc.jdedwards.JDEdwardsDriver',URL='jdbc:jdedwards:URL=https://your-jde-environment-app.example.com;User=admin;Password=myPassword;";
CONNECT USING SQLCA;
dw_accountspayable.accountledger.SetTransObject(SQLCA);
dw_accountspayable.accountledger.Retrieve();
