"Port 8761 was already in use" - port is actually free

I'm working with Eureka discovery server, and when I run the app I get:
2022-05-29 20:37:54.830 ERROR 19252 --- [ restartedMain] o.s.b.d.LoggingFailureAnalysisReporter :
***************************
APPLICATION FAILED TO START
***************************
Description:
Web server failed to start. Port 8761 was already in use.
Action:
Identify and stop the process that's listening on port 8761 or configure this application to listen on another port.
Process finished with exit code 0
However, the port is actually free. I check in Resource monitor and also through the cmd.
Other things I tried:
Changing the port of the discovery server, and still get same thing.
Restarting pc.
Ending tasks related to JDK
My properties file of the Discovery Server looks like this:
server.port=8761
spring.application.name=discoveryservice
eureka.client.registerWithEureka=false
eureka.client.fetchRegistry=false
eureka.client.serviceUrl.defaultZone = http://localhost:8761/eureka
eureka.instance.prefer-ip-address=true
spring.security.user.name=test
spring.security.user.password=test
Running the app with --debug :

please someone else suggests me to solve this problem.
I enable TSLv1.2 from Windows Server 2016 side and disabled TSLv1

add this property to application entry point
Security.setProperty("jdk.tls.disabledAlgorithms","SSLv3, RC4, DES, MD5withRSA, DH keySize < 1024,EC keySize < 224, 3DES_EDE_CBC, anon, NULL");
if you use spring boot
you can use like this
import java.security.Security;
public class Application {
public static void main(String[] args) {
Security.setProperty("jdk.tls.disabledAlgorithms","SSLv3, RC4, DES, MD5withRSA, DH keySize < 1024,EC keySize < 224, 3DES_EDE_CBC, anon, NULL");
SpringApplication.run(Application.class, args);
}
}

This issue got resolved for me when I replaced the sqljdbc-4.2.0 jar with mssql-jdbc-8.4.1 jar.
Another fixed for this error was enabling TLS 1.0 by iisencrypt.exe. However this solution to work needs your system to be restarted.
I would recommend to go with the first solution.
Add the below dependency in your pom.xml to add jar.
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>mssql-jdbc</artifactId>
<version>8.4.1.jre8</version>
</dependency>
Or you can add jar directly if it's not a maven project.

Not able to run jsp file in spring boot using embedded tomcat server

I have created a simple SpringBoot project to view jsp file.
Here is my Project tree -
This is MyappApplication.java
package com.simplespringboot.myapp;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class MyappApplication {
public static void main(String[] args) {
SpringApplication.run(MyappApplication.class, args);
System.out.println("Let's get started");
}
}
This is TestController.java
package com.simplespringboot.myapp;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
#Controller
public class TestController {
#RequestMapping("/")
#ResponseBody
public String handler() {
System.out.println("I am handler method");
return "HI there ";
}
#RequestMapping("/home")
public String home() {
System.out.println("I am home method");
return "home";
}
}
Application.properties
spring.mvc.view.prefix= /views/
spring.mvc.view.suffix=.jsp

I have no idea what is the error. Somebody, please help me here. I am using VSCode.

Open Command Palette and choose Maven: Add a dependency, type the missing jar name:
This is equals to add the following code in pom.xml:
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<version>10.0.4</version>
</dependency>
Then rebuild the project and see if the question goes away.

Spring Boot deploy with Tomcat

I want to deploy my first Java application - I have a place to deploy it. I made Spring Boot application with Tomcat. Using some web instruction I make a fat jar file (maven package). I have exceptions. I try to search for it, but any solutions isn't work for this.
What can I add - I do not setup Tomcat, simple base on maven package jar with Tomcat. Could someone tell me what I can do? I will be very grateful for your understanding and help. This is my first deploy.

Some items to check for here....
1 - Make sure you're including the Tomcat dependency in your POM.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</dependency>
2 - Check to see if your application.properties has the correct port number.
server.port=XXXX
3 - If this is running on a linux environment, try running the application with the following in your VM:
-Dserver.port=8181
4 - Make sure your Application Class extends SpringBootServletInitializer:
#SpringBootApplication
public class App extend SpringBootServletInitializer
{
public static void main( String[] args )
{
SpringApplication.run(App.class, "hello");
}
}

It seems that you do not configure a valid port, it should > 1024.

Filter registration with Spring Boot and Wicket AuthenticatedWebApplication

I am currently playing around with Apache Wicket 8 and Spring Boot. I made a simple web app with some panels, breandcrumbs dataprovider and so on. The app is working fine. In my Spring config class I've set up a Filter Bean. Now I want to implement authentication functionality. Hence I switched from extending Wickets WebApplication class to AuthenticatedWebApplication class and created a custom AuthenticatedWebSession.
When I now start the application I receive an WicketRuntimeException telling me to use Application.init() method to configure my application object. For some reason my Filter Bean cannot be instantiated anymore.
I tried to use a FilterRegistrationBean instead of Filter with the same effect.
Any suggestions on how to fix this?
Here is my config class with the FilterRegistrationBean:
#Configuration
#Import({PersistenceConfig.class})
public class SpringConfig {
// Either using Filter or FilterRegistrationBean is not working anymore
// #Bean
// public Filter getWicketFilter() {
// WicketApplication webApplication = new WicketApplication();
// webApplication.setConfigurationType(RuntimeConfigurationType.DEVELOPMENT);
// WicketFilter filter = new WicketFilter(webApplication);
// filter.setFilterPath("/");
// return filter;
//
// }
#Bean
public FilterRegistrationBean<WicketFilter> wicketFilterRegistration(){
WicketApplication webApplication = new WicketApplication();
webApplication.setConfigurationType(RuntimeConfigurationType.DEVELOPMENT);
WicketFilter filter = new WicketFilter(webApplication);
filter.setFilterPath("/");
FilterRegistrationBean<WicketFilter> registration = new FilterRegistrationBean<>();
registration.setFilter(filter);
registration.addInitParameter(WicketFilter.APP_FACT_PARAM,SpringWebApplicationFactory.class.getName());
registration.setDispatcherTypes(DispatcherType.REQUEST, DispatcherType.FORWARD);
return registration;
}
}
And here is the error:
Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.

As the exception message suggests you need to call application.init() after instantiating it.

as Martin suggested you should do it in your FilterRegistrationBean definition, i.e.:
#Bean
public FilterRegistrationBean<WicketFilter> wicketFilterRegistration(){
WicketApplication webApplication = new WicketApplication();
webApplication.setConfigurationType(RuntimeConfigurationType.DEVELOPMENT);
webApplication.init();//HERE!
BTW: consider to use the last 8.x version, which is 8.5.0

Unfortunately your solution was not working. Same error was thrown again. However I was able to identify the problem at the end.
Problem was in constructor of my Wicket Application class. In this constructor I called super.init(). After removing this application started without Bean Instantiation error.
public class WicketApplication extends AuthenticatedWebApplication {
// This caused the problem with instatiating the FilterRegistrationBean
// public WicketApplication() {
// super.init();
// }
#Override
protected void init() {
super.init();
getComponentInstantiationListeners().add(new SpringComponentInjector(this));
mountPage("/admin", AdminPage.class);
mountPage("/login", LoginPage.class);
}
#Override
public Class<? extends Page> getHomePage() {
return AdminPage.class;
}
#Override
protected Class<? extends AbstractAuthenticatedWebSession> getWebSessionClass() {
return AppAuthenticatedWebSession.class;
}
#Override
protected Class<? extends WebPage> getSignInPageClass() {
return LoginPage.class;
}
public static WicketApplication get() {
return (WicketApplication) Application.get();
}
}
