Integrate with FTP Data in JReport Designer

Create charts and reports based on FTP data in JReport Designer.

The CData JDBC Driver for FTP data enables access to live data from dashboards and reports as if FTP were a relational database, allowing you to query FTP data using familiar SQL queries. This article shows how to connect to FTP data as a JDBC data source and create reports based on FTP data in JReport Designer.

Connect to FTP Data

  1. Edit C:\JReport\Designer\bin\setenv.bat to add the location of the JAR file to the ADDCLASSPATH variable:
    ...
    set ADDCLASSPATH=%JAVAHOME%\lib\tools.jar;C:\Program Files\CData\CData JDBC Driver for FTP 2016\lib\cdata.jdbc.ftp.jar;
    ...
    
  2. Create a new data source by clicking File New Data Source.
  3. In the resulting dialog, create a name for the data source (CData JDBC Driver for FTP), select JDBC, and click OK.
  4. In the Get JDBC Connection Information dialog you will configure your connection to the JDBC driver:
    • Driver: Be sure that the Driver box is checked and fill in the name of the class for the driver: cdata.jdbc.ftp.FTPDriver
    • URL: Enter the JDBC URL. This starts with jdbc:ftp: and is followed by a semicolon-separated list of connection properties.

      To connect to FTP or SFTP servers, specify at least RemoteHost and FileProtocol. Specify the port with RemotePort.

      Set User and Password to perform Basic authentication. Set SSHAuthMode to use SSH authentication. See the Getting Started section of the data provider help documentation for more information on authenticating via SSH.

      Set SSLMode and SSLServerCert to secure connections with SSL.

      The data provider lists the tables based on the available folders in your FTP server. Set the following connection properties to control the relational view of the file system:

      • RemotePath: Set this to the current working directory.
      • TableDepth: Set this to control the depth of folders to list as views.
      • FileRetrievalDepth: Set this to retrieve and list files recursively from the root table.

      Stored Procedures are available to download files, upload files, and send protocol commands. See the Data Model chapter of the FTP data provider documentation for more information.

      Built-in Connection String Designer

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

      java -jar cdata.jdbc.ftp.jar

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

      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.

      Below is a typical JDBC URL:

      jdbc:ftp:RemoteHost=MyFTPServer;
    • User: The username to authenticate with; typically left blank.
    • Password: The password to authenticate with; typically left blank.
  5. In the Add Table dialog, select the tables you wish to include in your report (or in future reports using this data source) and click Add.

    Click Done once the dialog has completed loading the tables.

  6. In the Catalog Browser, you can create the queries that you will use to populate your reports. You can do this now, or after you create your report. In either case, expand () the data source (CData JDBC Driver for FTP), right-click on Queries, and select Add Query.
  7. In the Add Table/View/Query dialog, expand () the JDBC URL and Tables and select the table(s) you wish to use in the query and click OK.
  8. In the Query Editor dialog, you can select the columns you wish to include or simply click the SQL button and manually input your own query. For example:
    SELECT Filesize, Filename FROM MyDirectory
    

    With the query built, click OK to close the Query Editor dialog. At this point you are ready to add FTP data to a new or existing report.

    NOTE: Now that the query is built, you can create a Business View based on the query. With a Business View, you can create Web reports or library components based on the query. For more information on this, refer to the JReport tutorials.

Add FTP Data to a Report

You are now ready to create a report with FTP data.

  1. Create a new report (File New Page Report) or open the Chart Wizard for an existing report.
  2. Select the Query (or create a new one; see above).
  3. Assign a Category and Value for the chart from the columns in your Query and click Finish.
  4. Click the View tab for your report to see the chart.
