Putting the Codes into Gear

Now, let's put these codes into gear.

First we create a Java project, say, wineco:

New Wineco Java Project

Add the ASN.1 runtime to the build path of the Java project. Click here to download the latest ASN.1 Java Runtime for Java SE.

Add ASN.1 runtime to build path

Copy the generated Java code from project Wineco-protocol:

Copy Generated Code to project

Now, you can write your code to wire the protocol, here is a simple test code:

import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.util.Date;
import java.util.Vector;

import Wineco_returns_protocol.Report_item;
import Wineco_returns_protocol.Return_of_sales;
import Wineco_returns_protocol.Return_of_sales_Reason_for_delay;
import Wineco_returns_protocol.Return_of_sales_Time_and_date_of_report;
import Wineco_returns_protocol.Return_of_sales_Version;


public class Test {

	public static void main(String[] args) throws IOException {
		
		Return_of_sales return_of_sales = new Return_of_sales();
		
		return_of_sales.version = new Return_of_sales_Version(new byte[1],(byte)6);
		return_of_sales.version.setVersion1();
		
		return_of_sales.no_of_days_reported_on = 7;
		
		return_of_sales.time_and_date_of_report = 
			new Return_of_sales_Time_and_date_of_report(
					Return_of_sales_Time_and_date_of_report.four_digit_yearChosen, new Date());
		
		return_of_sales.reason_for_delay = Return_of_sales_Reason_for_delay.other;
		
		return_of_sales.additional_information = new Vector<String>();
		
		return_of_sales.sales_data = new Vector<Report_item>();
		Report_item report_item;
		report_item = new Report_item();
		report_item.item = new int[]{1, 2, 3, 4};
		report_item.item_description = "item1";
		report_item.bar_code_data = new byte[]{3, 5, 54, 54};
		report_item.ran_out_of_stock = false;
		report_item.min_stock_level = 100.0;
		report_item.max_stock_level = 500.0;
		report_item.average_stock_level = 250.0;
		return_of_sales.sales_data.add(report_item);
		
		report_item = new Report_item();
		report_item.item = new int[]{1, 2, 3, 5};
		report_item.item_description = "item2";
		report_item.bar_code_data = new byte[]{63, 35, 3, 45};
		report_item.ran_out_of_stock = true;
		report_item.min_stock_level = 255.0;
		report_item.max_stock_level = 500.0;
		report_item.average_stock_level = 256.0;
		return_of_sales.sales_data.add(report_item);
		
		ByteArrayOutputStream bos = new ByteArrayOutputStream();
		return_of_sales.ber_encode(bos);
		
		ByteArrayInputStream bis = new ByteArrayInputStream(bos.toByteArray());
		Return_of_sales return_of_sales1 = Return_of_sales.ber_decode(bis);
		
		System.out.println("Equality: "+return_of_sales.equals(return_of_sales1));
	}

}
