Tomcat 9 uses javax.servlet.Filter. Jersey 3.x, part of Jakarta EE 9, depends on jakarta based API packages. jakarta.servlet.Filter is available in Tomcat 10.
If you want to use Tomcat 9, use Jersey 2.x. If you want to use Jersey 3.x with Servlets, you need to use a servlet container that implements Servlet 5 API, e.g. Tomcat 10, Jetty 11, Glassfish 6.

the root of problem is here:
Failed to introspect bean class
[com.apurv.onlineshopping.controller.PageController] for resource
metadata: could not find class that it depends on
DI container can't find the class defined in another .jar
to solve the problem let's go through the code:
you inject a DAO component:
#Controller
public class PageController {
#Autowired
private CategoryDAO categoryDao;
which can be found by in packges (not .jars) defined in web.xml:
<context:component-scan base-package="com.apurv.onlineshopping.controller"/>
<context:component-scan base-package="com.apurv.shoppingbackend.daoImpl "/>
as I found your two modules disposited alone, so build system have no information where them can found dependency for onlineshopping until you instruact them by hand.
My solution is: to organize your two independend modules into parent-modules pom:
here id parent pom.xml:
<?xml version="1.0" encoding="UTF-8"?>
<project ...
<groupId>com.apurv</groupId>
<artifactId>so</artifactId>
<packaging>pom</packaging>
<version>1.0-SNAPSHOT</version>
<modules>
<module>shoppingbackend</module>
<module>onlineshopping</module>
</modules>
</project>
next put a ref to parent in your modules:
onlineshopping's pom.xml
<project ...
<modelVersion>4.0.0</modelVersion>
<!--unnecessary <groupId>com.apurv</groupId>-->
<artifactId>onlineshopping</artifactId>
<packaging>war</packaging>
<version>0.0.1-SNAPSHOT</version>
<name>onlineshopping</name>
<url>http://maven.apache.org</url>
<parent>
<groupId>com.apurv</groupId>
<artifactId>so</artifactId>
<version>1.0-SNAPSHOT</version>
</parent>
... tail of your code is unchanged ...
and shoppingbackend's pom.xml
<project ...
<modelVersion>4.0.0</modelVersion>
<!--unnecessary <groupId>com.apurv</groupId>-->
<artifactId>shoppingbackend</artifactId>
<packaging>jar</packaging>
<version>0.0.1-SNAPSHOT</version>
<name>shoppingbackend</name>
<url>http://maven.apache.org</url>
<parent>
<groupId>com.apurv</groupId>
<artifactId>so</artifactId>
<version>1.0-SNAPSHOT</version>
</parent>
... tail of your code is unchanged ...
Next build root module:
mvn package
Rest of your code is unchanged, you can found full repo rehe: https://github.com/enginetag/so-apurv

Alternate to mvn spring-boot:run

I have a spring boot application which I run using:
mvn spring-boot:run
and this works perfectly fine.
I want to run this application using java -jar option and when I run it:
java $JAVA_OPTS -jar target/backend-1.0-SNAPSHOT.jar --server.port=8080 $JAR_OPTS
I get this error:
org.glassfish.jersey.server.internal.scanning.ResourceFinderException: java.io.FileNotFoundException: /Users/cat/IdeaProjects/backend/target/backend-1.0-SNAPSHOT.jar!/BOOT-INF/classes (No such file or directory
I cant figure out why? And I have googled a lot without any luck.
Do we have an alternate to mvn spring-boot:run.
I want to do this because I am deploying on heroku and when I put in Procfile web: mvn spring-boot:run, I get errors such that mvn does not exist
EDIT
This is the code I am trying to run:

You can make your jar executable by configuring the spring boot maven plugin:
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<executable>true</executable>
</configuration>
</plugin>
Package your jar with
mvn package
You can then run your application by typing ./backend-1.0-SNAPSHOT.jar
https://docs.spring.io/spring-boot/docs/current/reference/html/deployment-install.html

To execute a jar as you try to do :
java $JAVA_OPTS -jar target/backend-1.0-SNAPSHOT.jar
--server.port=8080 $JAR_OPTS
You have to package your jar with the repackage goal of the spring boot maven plugin.
The repackage goal is bound to the package phase of the Maven lifecycle.
So this plugin configuration repackage a jar or war that is built during the package phase of the Maven lifecycle :
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
If you execute the mvn package goal (or a goal after it), it will create two JARs in the target folder of the Maven project :
the original JAR with a .original suffix (without the Spring boot classes and libraries to allow the jar to be self sufficient to be started)
the runnable JAR that will have the classic JAR name.
If you don't want to add this configuration, you can execute the repackage command directly from the Maven command :
mvn package spring-boot:repackage
Reference :
https://docs.spring.io/spring-boot/docs/current/reference/html/build-tool-plugins-maven-plugin.html#build-tool-plugins-maven-plugin

Anyone has an idea how to solve this?
Thank you

Hmm, obviously classloading problems with no very useful hint from the eclipse (osgi) framework...
I've seen from time to time failing apps when they bring their own versions of libraries which collide with some libs that are already part of the provided platform.
Consider this HCP maven blog: there they reference one artifact and most imporantly they use <scope>provided</scope> to tell maven to NOT include the libs into your app's war file (as some jars are already provided by the platform).
My best bet is that at least org.eclipse.persistence is already provided by the platform (and maybe other libs you want as well).

I faced the same error (my Q&A you can find here) and found a solution in this SAP discussion.
For me the error did no longer occur as soon as I added jersey manually and removed the <servlet-class> tag from the web.xml In the end the configuration within the web.xml wasn't necessary at all for my simple rest service (see this answer).
So It seems that this is a Hana cloud platform specific problem.

Jersey ClassNotFoundException when contextInitialized

When I connect to the selected servlet, it throw me a ClassNotFoundException. I am using eclipse neon with Tomcat8 and jersey RESTful framework. Its possible that I have the servlet conf in wrong in the web.xml?
Error showed:

Your web.xml content is incorrect, it matches with Jersey 2.x while you obviously use Jersey 1.x, indeed the package names start with com.sun.jersey in Jersey 1.x while in Jersey 2.x they start with org.glassfish.jersey.
Check here what should be the content of your web.xml in case of Jersey 1.x..
<servlet>
<servlet-name>jersey</servlet-name>
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>org.CTAG.DATEX2REST</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>jersey</servlet-name>
<url-pattern>/rest</url-pattern>
</servlet-mapping>
Or switch to Jersey 2.x.

Fixing the dependencies
You are mixing Jersey 1.x (com.sun.jersey) and Jersey 2.x (org.glassfish.jersey).
I understand you wan't to use Jersey 2.x, so remove:
<dependency>
<groupId>com.sun.jersey</groupId>
<artifactId>jersey-server</artifactId>
<version>1.9</version>
</dependency>
And then add to your pom.xml
<dependency>
<groupId>org.glassfish.jersey.containers</groupId>
<!-- if your container implements Servlet API older
than 3.0, use "jersey-container-servlet-core" -->
<artifactId>jersey-container-servlet</artifactId>
<version>2.23.2</version>
</dependency>
Deploying in a Servlet 2.x container (like Tomcat 6)
Jersey integrates with any Servlet containers supporting at least Servlet 2.5 specification. For these environments, you have to explicitly declare the Jersey container servlet in your web application's web.xml deployment descriptor file:
<web-app>
<servlet>
<servlet-name>MyApplication</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param>
...
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>MyApplication</servlet-name>
<url-pattern>/api/*</url-pattern>
</servlet-mapping>
</web-app>
The content of the <init-param> element will vary depending on the way you decide to configure Jersey resources.
Deploying in a Servlet 3.x container (like Tomcat 7 and above)
In a Servlet 3.0 container, you just need to implement a custom Application / ResourceConfig subclass. For simple deployments, no web.xml is necessary at all. Instead, an #ApplicationPath annotation can be used to annotate the custom Application / ResourceConfig subclass and define the base application URI for all JAX-RS resources configured in the application:
#ApplicationPath("api")
public class MyApplication extends ResourceConfig {
public MyApplication() {
packages("org.foo.rest;org.bar.rest");
}
}
For other deployment options, have a look at the documentation.
