zayit.exe appcrash when trying to open an HttpConnection - java-me

I am facing a problem while trying to open an HttpConnection in my J2ME app.
I am running the app using the emulator but when it comes to the line of code to open the HttpConnection as:
HttpConnection connection = (HttpConnection)Connector.open(URL);
a dialog appears saying that the app has crashed (zayit.exe).
What am I missing to configure?

I was trying to open Angular 8 with the Net Core application, which was deployed on the IIS server. It throws the error message on the console "Failed to load source: net:: ERR_CONNECTION_RESET". I found this bug in all browsers, not just Chrome. Can anyone help me solve this problem?
Thanks in advance.

Emulator fails with "Error connecting to the service protocol"

Launching App Remotely throws 'Unauthorized' Exception

I'm attempting to use the C# Windows Device Portal Wrapper to remotely launch a Hololens app from a PC. However, my code as posted below is throwing an 'Unauthorized' exception. From the Device Portal Wrapper source, it seems this exception is used for incorrect or missing credentials. However, I am 100% certain the credentials I'm using are correct.
private async Task LaunchApplication()
{
try
{
Debug.Log("Launching...");
await portal.LaunchApplicationAsync(appid, packageName);
Debug.Log("Launched");
}
catch (DevicePortalException e)
{
Debug.Log(e.Reason);
}
}
I am running this code as a UWP from the Unity Editor. According to the debug output, the Device Portal connection is successfully established, so there shouldn't be any issues there...
I'm not terribly experienced as a developer (college student), so I may be missing something obvious, but any help would be appreciated nonetheless! Thanks

How to check Internet Connection in Java ME?

I am developing a Java ME Application. Here I am doing HttpConnection as follows,
HttpConnection httpConnection = (HttpConnection) Connector.open( url.trim() );
Variable url is an valid url. Sometimes because of unavailability of GPRS Connection, I am getting error in HttpConnection Error. So can I check that my HttpConnection is done or not ?

You can use the getResponseCode() & getResponseMessage() of HttpConnection's API for the checking of Successful Connection.
getResponseCode() will return integer value 200 which means it is successful connection with server. 404 means Page not found.
