Import Real-Time HCL Domino Data in ColdFusion to Build Applications

Adobe ColdFusion is a web and mobile application development platform. It uses its own scripting language, ColdFusion Markup Language (CFML), to create data-driven websites as well as generate remote services, such as REST. When ColdFusion is paired with the CData ODBC Driver for HCL Domino, you can link your ColdFusion web and mobile applications to operational HCL Domino data. This allows for your applications to be more robust and complete. This article details how to use the ODBC driver to create a table populated with HCL Domino data from within a ColdFusion markup file.

To follow along with this tutorial, you need to install the CData ODBC Driver for HCL Domino and Adobe ColdFusion.

Configuring the Connection

If you have not already, first specify connection properties in an ODBC DSN (Data Source Name). This is the last step of the driver installation process. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Prerequisites

The connector requires the Proton component to be installed. Normally, Proton is distributed as part of the AppDev pack. See the HCL documentation for instructions on acquiring and installing Proton or the AppDev pack.

Once the Proton service is installed and running, you will also need to create a user account and download its Internet certificate. This certificate can be used to set the connector certificate connection properties.

Authenticating to Domino

• Server: The name or IP address of the server running Domino with the Proton service.
• Port: The port number that the Proton service is listening on.
• Database: The name of the database file, including the .nsf extension.
• SSLClientCertType: This must match the format of the certificate file. Typically this will be either PEMKEY_FILE for .pem certificates or PFXFILE for .pfx certificates.
• SSLClientCert: The path to the certificate file.
• SSLServerCert: This can be set to (*) if you trust the server. This is usually the case, but if you want to perform SSL validation, you may provide a certificate or thumbprint instead. See the documentation for SSLServerCert for details.

Additional Server Configuration

The connector supports querying Domino views if any are defined. Before views can be queried by the connector they must be registered with the design catalog.

Please refer to the Catalog Administration section of the AppDev pack documentation for details on how to do this.

Adding a Data Source and Creating a Table

After creating a DSN, follow the steps below to add a new data source, test our connection to it, create a ColdFusion markup file, and, finally, import HCL Domino HCL Domino data and display it in a table in ColdFusion:

1. From the ColdFusion administrator interface, choose Data & Services.
2. Here, click "Add New Data Source". The data source name can be any name, provided it conforms to the ColdFusion variable naming conventions. For our ODBC driver, choose "ODBC Socket", then click the "Add" button.
3. From the ODBC DSN Dropdown menu select CData HCL Domino Sys. Under the Advanced Settings section, leave the Connection String blank. Note that any properties specified in this input field will override the ones specified in the DSN Configuration.
4. Now, test the connection by pressing the check mark to the left of the CDataHCL DominoODBC data source you just created. When the data source reports an "OK" status, it is ready for use.
5. Next, create a new ColdFusion Markup file (.cfm) and place it in the wwwroot directory ("C:\ColdFusion2021\cfusion\wwwroot") for ColdFusion.

   The following code queries the data source:

               
           <cfquery name="HCL DominoQuery" dataSource="CDataHCL DominoODBC"> 
             SELECT * FROM ByName 
           </cfquery> 
       

   And a CFTable can be used to quickly output the table in HTML:

               
             <cftable  
             query = "HCL DominoQuery" 
             border = "1" 
             colHeaders 
             colSpacing = "2" 
             headerLines = "2" 
             HTMLTable 
             maxRows = "500" 
             startRow = "1"> 
   
             <cfcol header="<b>Name</b>" align="Left" width=2 text="Name"/> 
   
             <cfcol header="<b>Address</b>" align="Left" width=15 text="Address"/> 
   
             ...
   
           </cftable> 
       

   Full code, including the HTML portion is available below:

               
           <html> 
           <head><title>CData Software | HCL Domino ByName Table Demo </title></head> 
           <body> 
           <cfoutput>#ucase("HCL Domino ByName Table Demo")#</cfoutput> 
           <cfquery name="HCL DominoQuery" dataSource="CDataHCL DominoODBC"> 
   
             SELECT * FROM ByName 
   
           </cfquery> 
           <cftable  
             query = "HCL DominoQuery" 
             border = "1" 
             colHeaders 
             colSpacing = "2" 
             headerLines = "2" 
             HTMLTable 
             maxRows = "500" 
             startRow = "1"> 
             <cfcol header="<b>Name</b>" align="Left" width=2 text="Name"/> 
   
             <cfcol header="<b>Address</b>" align="Left" width=15 text="Address"/> 
   
             ...
   
           </cftable> 
           </body> 
   
           </html>  
       

6. Finally, run the code in a browser. It produces a table populated with HCL Domino data!

As a note, the CData ODBC Drivers also support parameterized queries using the cfqueryparam element. For example: SELECT * FROM Account WHERE name =
