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 JDBC 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 JDBC driver to create a table populated with HCL Domino data from within a ColdFusion markup file.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live HCL Domino data. When you issue complex SQL queries to HCL Domino, the driver pushes supported SQL operations, like filters and aggregations, directly to HCL Domino and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze HCL Domino data using native data types.

Configuring the Connection to HCL Domino

You will need a JDBC connection string to establish a connection between Coldfusion and HCL Domino.

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.

Built-in Connection String Designer

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

Adding a Data Source and Creating a Table

After configuring the connection, follow the steps below to add the CData JDBC Driver to ColdFusion's lib directory, add a new data source, test the connection, create a ColdFusion markup file, and, finally, make a real-time connection with HCL Domino data and display it in a table written in the ColdFusion Markup Language, or CFML:

1. Copy the JDBC Driver for HCL Domino and lic file from "C:\Program Files\CData[product_name]\lib" to "C:\ColdFusion2021\cfusion\wwwroot\WEB-INF\lib". cdata.jdbc.domino.jar cdata.jdbc.domino.lic

   Note: If you do not copy the .lic file with the jar, you will see a licensing error that indicates you do not have a valid license installed. This is true for both the trial and full versions.

2. From the ColdFusion administrator interface, choose Data & Services.
3. Here, we can "Add New Data Source". The data source name can be any name, provided it conforms to the ColdFusion variable naming conventions. For our JDBC driver, choose "other", then click the "Add" button.
4. Next, populate the driver properties.
   • JDBC URL will need to be in the format: jdbc:domino:|connectionString|.
   • A typical connection string looks like this:

     jdbc:domino:Server=https://domino.corp.com;Database=names.nsf;Port=3002;SSLClientCertType=PEMKEY_FILE;SSLClientCert=full_path_of_certificate.pem;SSLServerCert=*

   • The Driver Class is: cdata.jdbc.domino.DominoDriver
   • The Driver Name is arbitrary and simply used to recognize the data source in the ColdFusion administration console.
5. Now, test the connection by clicking the check mark to the left of the CDataHCL DominoJDBC data source you just created. When the data source reports an "OK" status, it is ready for use.
6. 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 DominoJDBC"> 
             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 DominoJDBC"> 
   
             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>  
       

7. Finally, run the code locally in a browser at the default port of 8500. It produces a table populated with HCL Domino data!

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