How to integrate HTML Table using Java

Learn how to quickly and efficiently connect HTML Table with Java for smooth data access.

Read HTML table data effortlessly. Extract, sync, and manage web table content for analytics, reporting, and data pipelines — almost no coding required. You can do it all using the high-performance HTML Table ODBC Driver for Java (often referred to as the HTML Table Connector). How is this possible? You will connect to the ZappySys Data Gateway, which acts as a seamless bridge between the ODBC and JDBC layers. We'll walk you through the entire setup.

Create data source in ZappySys Data Gateway

In this section we will create a data source for HTML Table in the Data Gateway. Let's follow these steps to accomplish that:

Download and install ODBC PowerPack (if you haven't already).
Search for gateway in the Windows Start Menu and open ZappySys Data Gateway Configuration:
Go to the Users tab and follow these steps to add a Data Gateway user:
- Click the Add button
- In the Login field enter a username, e.g., john
- Then enter a Password
- Check the Is Administrator checkbox
- Click OK to save
Now we are ready to add a data source:
- Click the Add button
- Give the Data source a name (have it handy for later)
- Then select Native -
- Finally, click OK
HtmlTableDSN
When the Configuration window appears give your data source a name if you haven't done that already, then select "HTML Table" from the list of Popular Connectors. If "HTML Table" is not present in the list, then click "Search Online" and download it. Then set the path to the location where you downloaded it. Finally, click Continue >> to proceed with configuring the DSN:

Now it's time to configure the Connection Manager. Select Authentication Type, e.g. Token Authentication. Then select API Base URL (in most cases, the default one is the right one). More info is available in the Authentication section.
Once the data source connection has been configured, it's time to configure the SQL query. Select the Preview tab and then click Query Builder button to configure the SQL query:

Read HTML table data effortlessly. Extract, sync, and manage web table content for analytics, reporting, and data pipelines — almost no coding required.

HtmlTableDSN
Start by selecting the Table or Endpoint you are interested in and then configure the parameters. This will generate a query that we will use in Java to retrieve data from HTML Table. Hit OK button to use this query in the next step.
```
SELECT * FROM Orders
```
Some parameters configured in this window will be passed to the HTML Table API, e.g. filtering parameters. It means that filtering will be done on the server side (instead of the client side), enabling you to get only the meaningful data much faster.
Now hit Preview Data button to preview the data using the generated SQL query. If you are satisfied with the result, use this query in Java:

HtmlTableDSN
```
SELECT * FROM Orders
```
You can also access data quickly from the tables dropdown by selecting <Select table>.

A WHERE clause, LIMIT keyword will be performed on the client side, meaning that the whole result set will be retrieved from the HTML Table API first, and only then the filtering will be applied to the data. If possible, it is recommended to use parameters in Query Builder to filter the data on the server side (in HTML Table servers).
Click OK to finish creating the data source.
Once done, go to the Network Settings tab and Add a firewall rule for inbound traffic:
- This will initially allow all inbound traffic.
- Click Edit IP filters to restrict access to specific IP addresses or ranges.
Crucial Step: After creating or modifying the data source, you must:
- Click the Save button to persist your changes.
- Hit Yes when prompted to restart the Data Gateway service.
This ensures all changes are properly applied:

Skipping this step may cause the new settings to fail, preventing you from connecting to the data source.

Read data in Java from the DSN

Java code to get the data:

"jdbc:sqlserver://localhost:5000;databasename=HtmlTableDSN;user=john;password=test"
When you run the code it will make the API call and read the data:

Here is Java program's code in text format:

public class zappy {

    public static void main(String[] args) {

        // Create a variable for the connection string.
        String connectionUrl = "jdbc:sqlserver://localhost:5000;databasename=HtmlTableDSN;user=test;password=test";

        // Declare the JDBC objects.
        Connection con = null;
        Statement stmt = null;
        ResultSet rs = null;

            try {
                // Establish the connection.
                Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
                con = DriverManager.getConnection(connectionUrl);

                // Create and execute an SQL statement that returns some data.
                String SQL = "SELECT Country , SUM(UnitPrice * Quantity) Total " 
                           + "FROM value " 
                           + "GROUP BY Country "
                           + "WITH (SRC='https://services.odata.org/V3/Northwind/Northwind.svc/Invoices?$format=json')";
                stmt = con.createStatement();
                rs = stmt.executeQuery(SQL);

                // Iterate through the data in the result set and display it.
                while (rs.next()) {
                    System.out.println(rs.getString(1) + " " + rs.getString(2));
                }
            }

        // Handle any errors that may have occurred.
        catch (Exception e) {
            e.printStackTrace();
        } 
        
        finally {
            if (rs != null) try { rs.close(); } catch (Exception e) {}
            if (stmt != null) try { stmt.close(); } catch (Exception e) {}
            if (con != null) try { con.close(); } catch (Exception e) {}
        }
    }
}
