I was trying out Log4j2 so I created a Java project in eclipse. My code is same as Log4j2 Manual Automatic Configuration part. I have added log4j-api-2.17.2.jar and log4j-core-2.17.2.jar in the classpath. When I run the application I get following error
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/logging/log4j/LogManager
at demo.one.MainClass.<clinit>(MainClass.java:8)
Caused by: java.lang.ClassNotFoundException: org.apache.logging.log4j.LogManager

I have checked some related questions but didn't find those useful.
In case you use maven, make sure to include Log4j core to the project:
<!-- https://mvnrepository.com/artifact/org.apache.logging.log4j/log4j-core -->
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-core</artifactId>
<version>2.18.0</version>
</dependency>
Since, it's a NoClassDefFoundError, that means your JRE is not able to find out the necessary jar(class) artifact holding definition for org.apache.logging.log4j.LogManager.
Look for differences between build and runtime classpaths.
EDIT: Just realised it's caused by a ClassNotFoundException, would still like some help.
I'm trying to update keycloak from version 12.0.3 to version 13.0.0, however when I make that change I get the following error:

I tried updating the fasterxml databind package too, but it didn't make any difference.
I noticed that the path to the correct jar in the maven repository is different to the path in the error.
In the maven repository there are stored at com/fasterxml/jackson/core/databind.
Does that have any baring on the issue?
How can I fix this?
EDIT 2:
In the parent pom we have this:
<dependency>
<groupId>com.fasterxml.jackson.datatype</groupId>
<artifactId>jackson-datatype-jsr310</artifactId>
<version>2.9.8</version>
</dependency>
The only change made to the module pom was to increase the version as stated above.
looking at the dependency analyser for jackson-databind it does look a bit of a mess, I should also point out that we're using the maven shade plugin:

Appreciate any kind of help.
I faced the similar issue. I was using AWS JavaV2 SDK software.amazon.awssdk with version 2.19.14.
The Amazon Java SDK jar that I had imported had a dependency on org.apache.httpcomponents. Once I imported the dependency and built the project again, I was able to create the client.
My pom.xml looked something like this.
<dependencies>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
</dependency>
<dependency>
<groupId>software.amazon.awssdk</groupId>
<artifactId>ssm</artifactId>
</dependency>
</dependencies>
Is there any simple way to generate Spring Boot Mvc project for .jsp views?
I've tried to create project in similar way like Spring Boot Rest project, but it's not soo easy for me. I've tried to use official Spring Boot Mvc jsp sample, but when I try to run this I get exception like this:

This blog post explains what steps you should take and why. Its fairly easy and I've fixed it myself.
TD:LR
Add Maven Dependencies
In order to enable JSP support, we need to add a few dependencies to our new project in pom.xml.
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
Place the JSP templates under src/main/resources/META-INF/resources/WEB-INF/jsp/
As I know, the spring boot default page technology is thymeleaf and the official recommends us to use it.
If you want to use jsp, you could do some configuration.
The following steps may be useful.
1. Creating src/main/webapp/WEB-INF/jsp folder.
2. Modify application.properties file.
spring.mvc.view.prefix: /WEB-INF/jsp/
spring.mvc.view.suffix: .jsp
3.Add jar support for jsp. You could add the followings maven repository to your project pom.xml file.
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
Hope it helps. Any concerns, please feel free to let me know.
Add below dependencies to your POM file:
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
Create below structure
/src/main/resources/META-INF/resources
Now the above folder is equivalent to your WebContent folder. Inside this you can put your static contents. Add WEB-INF folder here and now you can place your JSP files like any other web project.
In your application.properties file add below:
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
Any chance you're running in IntelliJ? I've noticed this issue as well and the solution is to remove the <scope>provided</scope> from the spring-boot-starter-tomcat dependency, like this:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<!-- <scope>provided</scope> -->
</dependency>
There's a bug in IntelliJ, causing it not to add provided dependencies to the classpath when running locally.
EDIT: Removing the provided scope might cause issues when you're going to run it within a servlet container, so be cautious about that, an explanation about how to fix that could be found in Run Spring-boot's main using IDE.
I have had similar problems, see the link to github.
jsf-spring-boot-2.1.6 parent use spring boot 1.4.0
everything has worked and there is no problems, believe it or not!
https://github.com/joinfaces/joinfaces-example-war
Adding dependency in POM file below
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
Full code avaliable on github link click here
Download the code and import the eclipse/STS using exiting maven project
Next to run the project.
Go to the package on com.chandrakumar.test.demo.
it has "DemoApplication.java" and right click the mouse and select run as
choose the java application.
The browser address bar type "http://localhost:8080/".
Following johnny's reply, I actually wasn't aware that JSP files could be ran while deploying the application as a JAR. Though apparently there are some extensions that I haven't heard of... Typically, a JSP application is deployed as a WAR, and all JSP-related files are located in the webapp/WEB-INF/ folder. You may need to add <packaging>war</packaging> to your POM if if you are comfortable packaging your application as a WAR. This doesn't sound like a bad idea if your application is not a microservice or does not utilize cloud-based technologies. But the majority of cloud-based technologies (excluding cloud-foundry and maybe some others) only support JAR packaging. In that case, you may want to use alternative templates such as Thymeleaf or FreeMarker, over JSP, if you decide to go the JAR route.
Use a maven run configuration with spring-boot:run as the "Command line" value.
I've developed some code that executes a quartz job.At first the code was outside the tomcat and it executes very well, but when I tried to embed the same code inside a web application I get java.lang.NoClassDefFoundError: org/quartz/DisallowConcurrentExecution.
I'm using quartz 2.1.5 and it's already in the class path.
Here is the stack trace:
Exception in thread "DefaultQuartzScheduler_QuartzSchedulerThread" java.lang.NoClassDefFoundError: org/quartz/DisallowConcurrentExecution
INFO: Illegal access: this web application instance has been stopped already. Could not load org.quartz.DisallowConcurrentExecution. The eventual following stack trace is caused by an error thrown for debugging purposes as well as to attempt to terminate the thread which caused the illegal access, and has no functional impact.

make sure you have only 1 quartz-all-.jar in your classpath (maybe you have 2 : 1 in Tomcat lib folder + 1 in your war)
NoClassDefFoundErrors point to a missing JAR or class on the classpath. In this case the problem is likely that in Tomcat you have quartz-<ver>.jar on your classpath when you actually need quartz-all-<ver>.jar.
for them who use maven can use the new version by add
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>2.1.7</version>
</dependency>
It should be keep the .jar file inside of the project location. Import .jar file from the outside from the location which the project have is the reason for getting this error. also verified that if the project is a maven project, then it should include the maven dependency in the pom.xml to add the dependency to the project
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>2.3.2</version>
</dependency>
<dependency>
<groupId>org</groupId>
