JReport Designer でSFTP Data を連携

JReport Designer でSFTP data に連携するチャートとレポートを作成します。

CData JDBC Driver for SFTP を使用すると、SFTP がリレーショナルデータベースであるかのようにダッシュボードやレポートからライブデータにアクセスでき、使い慣れたSQL クエリを使用してSFTP data をクエリできます。ここでは、JDBC データソースとしてSFTP data に連携し、JReport Designer でSFTP data のレポートを作成する方法を説明します。

SFTP Data に接続

  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 SFTP 2016\lib\cdata.jdbc.sftp.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 SFTP), 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.sftp.SFTPDriver
    • URL:Enter the JDBC URL.This starts with jdbc:sftp: and is followed by a semicolon-separated list of connection properties.

      SFTP can be used to transfer files to and from SFTP servers using the SFTP Protocol. To connect, specify the RemoteHost;. service uses the User and Password and public key authentication (SSHClientCert). Choose an SSHAuthMode and specify connection values based on your selection.

      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 subfolders to report as views.
      • FileRetrievalDepth: Set this to retrieve files recursively and list them in the Root table.
      Stored Procedures are available to download files, upload files, and send protocol commands. See gdatamodel for more on using SQL to interact with the server.

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

      java -jar cdata.jdbc.sftp.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:sftp: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 SFTP), 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 WHERE FilePath = /documents/doc.txt
    

    With the query built, click OK to close the Query Editor dialog.At this point you are ready to add SFTP 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.

レポートにSFTP Data を追加

You are now ready to create a report with SFTP 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.
