kandi X-RAY | grizzly Summary

grizzly is a Java library typically used in Networking, HTTP, Framework applications. grizzly has no bugs, it has build file available and it has high support. However grizzly has 6 vulnerabilities and it has a Non-SPDX License. You can download it from GitHub, Maven.

Writing scalable server applications in the Java programming language has always been difficult. Before the advent of the Java New I/O API (NIO), thread management issues made it impossible for a server to scale to thousands of users. The Grizzly NIO framework has been designed to help developers to take advantage of the Java NIO API. Grizzly’s goal is to help developers to build scalable and robust servers using NIO as well as offering extended framework components: Web Framework (HTTP/S), WebSocket, Comet, and more!.

Wicket (9.8.0) application using EJB injection throws exception while deploying on Payara 5.201

Asked 2022-Apr-05 at 09:31

I am trying to use WicketTester for application containing EJB injection related code.

I created application using 'wicket.apache.org/start/quickstart.html', and deployed it on Payara server '5.201'.

Deployment was successful, and I was able to see the page on web browser.

Tests written for the page were also executed successfully.

Once that was done, I added following dependencies in POM.xml

Is there a way to set up a "https to http" middle in GCP?

Asked 2022-Jan-28 at 23:59

I hope this isn't a duplicate question. I set up a simple Java server based on Grizzly in GCP. It is an HTTP server servicing requests on 8080. I have not been able to set up an HTTPS server (and I tried...) and the server (which responds publicly to postman, curl, etc.) cannot receive any requests from my public website, since the website is on HTTPS. So when sending a request, this error obviously appears:

ANSWER

Answered 2022-Jan-15 at 18:05

Looks like Grizzly is trying to obtain the hostname from the Host header in the request. Since HTTP 1.1 the Host header is required but if the Host header is set an empty name, Grizzly cannot obtain the name and throws an exception.

The Host request header is set by the HTTP client. But even if the Host header exists but its value is empty due to some reason the exception will be thrown.

Grizzly Code: the code that throws the Exception

According to the Javadocs for Grizzly you can set the default hostname by calling the setDefaultHostName(String defaultHostName) method, but the instance of the Mapper in the HttpHanderChain instance is not exposed. The default value set in HttpHanderChain of the Mapper instance is set to "localhost".

The best way to do this would be placing the functions in some kind of container (for example an array or a map) (in case you later want to export other functions from the file that don't create cards). Here's the simplest way with an array:

My program is a guessing game that has three questions the user tey to guess the answers of the 3 questions and they have only three chances if they did make three mistakes the program restart again but if they answer the 3 questions before their 3 chances finished they get their score at the end.

When the user enters a wrong answer from their first try it automatically goes to the second question.

You need to start again at the top of the while loop when they have given an incorrect answer.

So, you see wherever you have print("please try again"). After this, put down continue in a new line.

This will cause the program to start again at the top of the while loop.
