By opening up HttpsURLConnection to your Java servlet or jsp based Notification Listener, you can test your listener in your local machine without communicate to eBay Notification server.
To test whether the Java listener is able to respond with a standard URL status using the attached ListernerTestDriver program, you need to follow these steps:
1. Subscribe to the specific notifications by setting the ApplicationURL to a URL that starts with HTTPS in your SetNotificationPreferences request
2. Save the received email notification in your local file system.
3. Set listenerURL, notificationEvent and notificationXmlFileName properties in listener.properties file and execute the java standalone program ListenerTestDriver as below:
java -cp .;%CLASSPATH% ListenerTestDriver
Here is the sample output if your listener is running as expected.
public class ListenerTestDriver {
private static String file = "listerner.properties";
private static Properties config;
public static void main(String[] args) throws Exception{
config = new Properties();
try {
config.load(new FileInputStream( file));
} catch (IOException e) {
System.out.println("listerner.properties file is missing from the current working directory.");
return;
}
ListenerTestDriver sc = new ListenerTestDriver();
try {
//open the connection with the servlet
URL url = new URL(listenerURL );
HttpURLConnection conn = (HttpURLConnection)url.openConnection();
//send the xml to the servlet
out.writeBytes(fileContent);
out.flush();
out.close();
conn.disconnect();
System.out.println(conn.getURL());
System.out.println(conn.getResponseCode() +" " + conn.getResponseMessage());
}catch (Exception e){
e.printStackTrace();
}
}
private String readFileIntoString(String fileName) {
String fileContentInString = "";
try {
File soapFile = new File(fileName);
byte fileContent[] = new byte[ (int) soapFile.length()];
FileInputStream soapFileIS = new FileInputStream(soapFile);
soapFileIS.read(fileContent, 0, fileContent.length);
fileContentInString = new String(fileContent);
} catch (Exception ex) {
throw new RuntimeException(ex);
}
return fileContentInString;
}
