How to set Neo4J data as a JDBC data source in FineReport.

The CData JDBC Driver for Neo4J fully implements the JDBC standard and can provide Neo4J data connectivity to a wide variety of BI, reporting, and ETL tools and custom applications. In this article, we explain how to set Neo4J data as JDBC data source in FineReport and view Neo4J data as a table in the Report Designer.

Set Up a JDBC Data Source of Neo4J Data

Follow the instruction below to set Neo4J data as a FineReport database connection.

  1. Copy the cdata.jdbc.neo4j.jar file from the lib folder in the CData JDBC Driver for Neo4J installation directory to the lib folder of the FineReport installation directory. You will need to copy the cdata.jdbc.neo4j.lic file as well.
  2. From the Server tab, select Define Data Connection, click to add a new connection, and click JDBC.
  3. πŸ‘ FineReport Server Tab (Salesforce is shown.)

Next we will set up the data connection definition in the window.

  1. Database: Others
  2. JDBC Driver: cdata.jdbc.neo4j.Neo4jDriver
  3. URL: A standard JDBC connection string using semicolon-separated connection properties.

    To connect to Neo4j, set the following connection properties:

    • Server: The server hosting the Neo4j instance.
    • Port: The port on which the Neo4j service is running. The provider connects to port 7474 by default.
    • User: The username of the user using the Neo4j instance.
    • Password: The password of the user using the Neo4j instance.

    Built-in Connection String Designer

    For assistance in constructing the JDBC URL, use the connection string designer built into the Neo4J JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

    java -jar cdata.jdbc.neo4j.jar
    

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

    πŸ‘ Using the built-in connection string designer to generate a JDBC URL (Salesforce is shown.)

    When you configure the JDBC URL, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

    A typical JDBC URL is below:

     jdbc:neo4j:Server=localhost;Port=7474;User=my_user;Password=my_password;
     
  4. πŸ‘ FineReport data connection definition window (Salesforce is shown.)
  5. Click Connection pool attributes and set Test before getting connections to No.
  6. πŸ‘ FineReport connection pool (Salesforce is shown.)

Click Test connection to ensure you have configured the connection properly. With the connection to Neo4J set up, you can use it as FineReport data source.

Select Neo4J Data in the Report Designer.

  1. Click to add a new template data set and select DB query to open the database query window.
  2. πŸ‘ Adding a new DB query.
  3. Choose the JDBC connection that you created from the dropdown list.
  4. The Neo4J entities will appear as tables on the left pane.
  5. Write a SELECT statement for the Neo4J data tables and columns that you want to load.
  6. πŸ‘ FineReport database query (Salesforce is shown.)
  7. Click preview and data is shown as table.
  8. πŸ‘ FineReport database query preview (Salesforce is shown.)

With these simple steps, Neo4J can be used as a JDBC data source in FineReport.
