I am trying to deploy the spring boot application in external jetty server. I build the application with maven build tool by excluding the tomcat in pom.xml file and the able to generate the war file.
pom.xml:
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jetty</artifactId>
</dependency>
</dependencies>
When I deploy the generated war file into webapp folder the war file is not getting extracted by jetty server.
I even tried to extract manually and try to access the application by postman, but no luck.
But same application when I try to run jar file instead of war file, it works fine.
Can I know how to deploy the spring boot application in jetty server.
Note: In code level I do not made any code change apart from the pom.xml to make application run in external jetty server.

I'm working with Spring Boot 2.4.4 and I would change the default web server Tomcat to undertow orJHetty but I find it very difficult using both Gradle or Maven.
An old documentation exposes how do it but I'm sure all is changed because now tomcat, undertow and jetty configuration is embedded in the core library:
https://docs.spring.io/spring-boot/docs/2.1.9.RELEASE/reference/html/howto-embedded-web-servers.html
How do it in the 2.4.4 version?
There are no changes between the versions. This is well described right at the Spring Boot 2.4.4 Reference guide, right in 3.1. Use Another Web Server section. Basically, the change consists of two steps:
Exclude embedded Tomcat server dependency from the spring-boot-starter-web artifact:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<!-- Exclude the Tomcat dependency -->
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
Include your embedded server as a separate dependency instead:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jetty</artifactId>
</dependency>
Just don't forget to notice the following quote from the reference guide in the very same section which might or might not be relevant to you:
The version of the Servlet API has been overridden as, unlike Tomcat 9 and Undertow 2.0, Jetty 9.4 does not support Servlet 4.0.
follow three steps to change the default web server, change configuration in pom.xml.
1.exclude the default web server.
2.Include the necessary web server.
3.Maven update.
For example,
Instead of this
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</dependency>
Add this one
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jetty</artifactId>
</dependency>
for the necessary server add the appropriate web server dependency.
Automaticall deploy my spring boot application file changes without manually restarting the server.
Use the following dependency:
<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-devtools -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<version>1.3.0.RELEASE</version>
</dependency>
I've followed all the steps mentioned in the documentation to enable the traditional war deployment for spring boot app i.e excluded the EmbeddedServletContainerAutoConfiguration from the #EnableAutoConfiguration and I only have one such instance. Also extended SpringBootServletInitializer and make sure the packaged war doesnt have any tomcat starter dependency. Also ran the spring boot report and confirmed the EmbeddedServletContainerAutoConfiguration is in the exclusion list.
Apart from all the changes when I deploy the war it is still creating a embedded application context with embedded servlet contatiner.
What did I miss and what other areas can I inspect ? Spring boot version 1.5.13.

Hi Veeram,
We do not need to exclude the AutoConfiguration-classes, but excluding the tomcat dependency is needed.
You need to do is omit tomcat starter dependency from pom.xml. It gets pulled from spring-boot-starter-web as a transitive dependency. So, you need to add exclusion for it:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
Now, as you are using <packaging>war</packaging> and using SpringBootServletInitializer, we would need servlet-api dependency on the classpath.
So, add the servlet dependency to your pom.xml
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.0.1</version>
<scope>provided</scope>
</dependency>
Hope this helps!
The application is deployed in pivotal web services and when I hit the application with the link https://webstore.cfapps.io/, the login.jsp page is not rendered.
The same application runs successfully in the local server. I tried for searching the same issue but none of them solve the problem. I used both STS deployment and also tried cf command line for deploying separately but couldn't get the result.
I am giving you the details.
The error shown.
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

6. I went to myapp in pivotal and started the application after binding the database cleardb to the same instant and application, the application runs successfully with the Running Status
7. the folder arrangement is as follows:
I have kept jsp pages in
src/main/webapp/WEB-INF/jsp/login.jsp
While the application.properties is in src/main/resources.
I will provide more details if needed. the github link for the code is
here
you are packaging it as a jar not as a war . In that case put your jsp files into static folder under resources or follow the below the link to understand better on the packaging aspect. But I feel it is better to package it as a war
Package a spring boot application including JSPs and static resources.
Also please check the jar generated before pushing the app to PWS whether jsp is avaibale at the requested path.
I want to build a application which is not an web application using spring boot.
I'm using apache qpid jars to connect to service bus queue, and my application is consumer to the queue.
I'm using following dependency in my application, my application is not a web app and hence I'm removing the tomcat dependency. My app is packaged as jar.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
My application runs fine, but it's getting shutdown by itself.
Any idea on what am I missing here?
Thanks.
