Rsocket client example: Invalid handshake response

Rsocket client example: Invalid handshake response - rsocket-java

I am running the ExampleClient on https://github.com/rsocket/rsocket-java#trivial-client with Java 11 in Eclipse but having Invalid handshake response getStatus: 404 Not Found error

It seems the websocket resource is unavailable or my RsocketcConnector is missing some configuration. Any suggestion?

Strange issue in quarkus pod initialization after openshift cluster starts

I'm using quarkus oidc to protect a resource through keycloak. This is the code used:
#Path("/api")
public class NamasteResource {
#Inject
JsonWebToken jwt;
#GET
#Path("health")
#Produces(MediaType.TEXT_PLAIN)
public String health() {
return "I'm ok";
}
#GET
#RolesAllowed("USERS")
#Path("namaste-secured")
#Produces(MediaType.TEXT_PLAIN)
public String namasteSecured() {
String userName = jwt.getName();
return "Hello " + userName;
}
}
The health resource is used for pod's readiness probe.
The issue here is that when openshift cluster starts and pod is deployed, I get an internal server error and the application doesn't work anymore. This is the exception trace:
2021-06-24 01:59:44,457 ERROR [io.qua.ver.htt.run.QuarkusErrorHandler] (vert.x-eventloop-thread-0) HTTP Request to /api/health failed, error id: 80e18320-2973-48c6-a377-edfc0f1db56b-1: io.quarkus.oidc.OIDCException: Tenant configuration has not been resolved

I have tried delaying pod initialization health check time, but always get the exception only the first time the pod is deployed.
If pod redeploy is made, then all works fine.
So, what should I do to make success pod initialization after openshift cluster starts?
This is my application.properties file configuration:
quarkus.http.cors=true
quarkus.oidc.auth-server-url=http://keycloak-myproject.192.168.1.110.nip.io/auth/realms/secured-realm
quarkus.oidc.client-id=namaste
I'm using Openshift 3.11 and quarkus 1.13.6.Final version

It is most likely to do with Keycloak not ready yet by the time the pod is deployed - quarkus-oidc does not try a different connection logic when it is deployed in OpenShift, all it does it always attempts to connect to URL set in quarkus.oidc.auth-server-url.
The way to handle it in 1.13.x is to use a quarkus.oidc.connection-delay property, for example, set it to 3M, etc - quarkus-oidc will keep trying to connect for 3M in this case. Here there is a small race condition that even if Keycloak becomes contactable it may still have not finished loading a custom realm file as has been discovered recently by a Quarkus user - a PR will be opened soon to resolve this particular issue.
The best option is to try 2.0.0.CR3 - there quarkus-oidc will recover even if the connection to Keycloak has failed at the start up.

simple app not starting (spring boot and MySQL)

I created application with Spring Boot and H2 embedded database.
Now I tried to use a MySQL db.
So I followed a simple guide from spring.io site, but my app does not start.
This is the error message I encountered:
Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

My app is very simple I created the Spring Boot app with just 3 dependencies:
spring web starter,
spring data jpa
my SQL driver
I have my model class:
package com.example.demo.model;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
#Entity
public class Customer {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private int cId;
private String cName;
private String cEMail;
default constructor..
constructor with fields..
getters and setters..
toString..
}
My CustomerRepo class:
package com.example.demo.dao;
import org.springframework.data.jpa.repository.JpaRepository;
import com.example.demo.model.Customer;
public interface CustomerRepo extends JpaRepository<Customer, Integer>{ }
My controller class:
package com.example.demo.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;
import com.example.demo.dao.CustomerRepo;
import com.example.demo.model.Customer;
#RestController
public class CustomerController {
#Autowired
private CustomerRepo repo;
#GetMapping("/add/{cId}")
public String home(#PathVariable("cId") int cId) {
Customer customer = repo.findById(cId).orElse(null);
return customer.toString();
}
}
My main class:
package com.example.demo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class ProvaApplication {
public static void main(String[] args) {
SpringApplication.run(ProvaApplication.class, args);
}
}
My application.properties file
spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mysql:localhost:3306/LENOVO-PC
spring.datasource.username=sa
spring.datasource.password=sapassword
I'm using sequel server management studio:
sql server screenshot
What is wrong with my code?

I made two changes,
1)I added #Repository to my CustomerRepo class (whit this change alone, nothing changed)
2)I added the two "/" before "localhost" in:
spring.datasource.url=jdbc:mysql:localhost:3306/LENOVO-PC
Now is giving me another error..

I think there is something with db configuration..

As you mentioned, the JDBC link should have the following format:
jdbc:mysql://localhost:3306/database-name
From the latest error you have posted, it looks like your sql server is not running probably.
Also I think you need to enable the entity scanning:
#Configuration
#EntityScan(basePackages = {"com.example.demo.model"})
#EnableJpaRepositories(basePackages = {"com.example.demo.dao"})
public class DomainConfig {
}
#Repository is not needed with #EnableJpaRepositories.
You can create an example project at https://bootify.io for a running MySQL Config.

Communication link failure error in spring boot

I have been trying to connect a database to my spring boot application but it didn't work out and give me an error. So, if anyone could give me a hint about what should I do?
I have tried to remove and add dependencies in pom.XML but nothing solved the issue
Backstory: I am trying to do a college project that is a web-service for an online store platform but this is my only error if the database connection succeeded I think there will be no other errors. I see an answer for another question have the same problem but non of the answers solved my problem

Glassfish IO hangs at video requests from client

I m having a Glassfish server 3.1.2 which is having some mp4 files.
Now when some of the videos are requested by google chrome the server hangs and any subsequent requests to the server are failed.
On shutting down the client browser(Chrome) the server recovers.
I m having a blog here at - blog.nvoids.in which is having some mp4 files.
On accessing the site from Chrome the server hangs as the mp4 files are based out of Glassfish server.
The logs at the server says -

As per the replies to Shay's blog entry on deploying to ADF Essentials (https://blogs.oracle.com/shay/entry/deploying_oracle_adf_applications_to):
"The ADFGlassFishAppLifeCycleListener is part of the adf-share-glassfish.jar file that will be added to your EAR file if you let JDeveloper know that you are deploying to GlassFish through the deployment profile at the application level (steps 4,5 above). If you have the only instance of JDeveloper where this doesn't happen - then just add that JAR manually to your EAR."
