I have not been using activity for a very long time, but my suggestion is to implement a new service task that connects to the external database.

I have a piece of code that I use to connect and creates a statement.
<code>
protected Statement createStatement(String dataSourceUrl, String dataSourceUsername, String dataSourcePassword){
     Connection conn = null;
Statement stmt = null;
     try {
         conn = DriverManager.getConnection(dataSourceUrl, dataSourceUsername, dataSourcePassword);
     } catch (SQLException e) {
      logger.error("Cannot get connection: " + e.getMessage());
         return null;
     }

     try {
         stmt = conn.createStatement();
     } catch (SQLException e) {
      logger.error("Cannot create statement: " + e.getMessage());
         return null;
     }
     return stmt;
    }
</code>
