I am configuring Jersey 2.25.1 to run on Jetty 9.4.4 server without an Application subclass. Jetty supports Servlet API 3.1 so I configure my application for this environment exactly as the documentation said, thus my web.xml is
<web-app version="3.0"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<!-- Servlet declaration can be omitted in which case
it would be automatically added by Jersey -->
<servlet>
<servlet-name>javax.ws.rs.core.Application</servlet-name>
</servlet>
<servlet-mapping>
<servlet-name>javax.ws.rs.core.Application</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
</web-app>
and pom.xml besides other contains the following Jersey related dependencies
<dependency>
<groupId>org.glassfish.jersey.containers</groupId>
<artifactId>jersey-container-servlet</artifactId>

After I deploy my war and start the server I get javax.servlet.UnavailableException: No class in holder javax.ws.rs.core.Application exception. Here is full stack trace:

I have created a controller service to connect to a test db.
I have a custom processor that reads data from SQL Server, the mock tests, the build and the deployment to NiFi succeed. The processor runs into error, maybe the nar dependency scope is at fault or ... ?
I am unsure The pom for processor and the nar projects are as follows :

In the controller service, I do not see my custom processor in
'Referencing Components'(it says 'no referencing components')
Right now, I have hard-coded the 'Database Driver Location(s)' but in
production, I would like the controller to pick up that from the
classpath(somehow, is it possible?)
*****Edit-1*****
As suggested by Mahendra, I did the following :
Without any changes to the existing pom.xml files, added the dependency (sqljdbc4, 4.0) to both, the build and deployment succeeded but the jdbc driver error persisted
The 'Database Driver Location(s)' kept as 'file:///'. Same error
Added the sqljdbc4.jar in NiFi/lib and the driver error vanished(getting other errors but those will be taken in a different thread). Note that the controller service still doesn't show the processor as 'referenced component'.
The java version
java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)
Isn't there a way to avoid adding the sqljdbc4.jar in lib, I mean third-party dependencies like fasterxml etc. are behaving properly, is this an issue with my configuration or some problem with the sql server maven repos. ?
#kaliyug,
EDIT 1:
1.if you declared DB class name is "com.microsoft.sqlserver.jdbc.SQLServerDriver".You should add below maven dependency in pom like below.,
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>sqljdbc4</artifactId>
<version>4.2</version>
</dependency>
Or If you want's to use in production environment you can specify driver database location in controller service like below.
file:///C:\DBLocation\sqljdbc42.jar
3.Or you can just copy the "sqljdbc42.jar" directly into NiFi\Lib directory.After copied the jar,you should restart NiFi Services.At runtime ,SQL jar automatically Loaded when it search for DB ClassName in Nifi\Lib directory.
Please let me know if you have face any issues.
I am building a system using Spring Boot. I am using Spring Tools Suite as the IDE, and I can build and run the program as Spring Boot App using Spring Tool Suite without any problems. However, when I build via maven via command "mvn package", and run the generated jar file under target/my-app.jar, the embeded tomcat failed to start. The error is like below:

Any suggestions will be greatly appreciated!
I have figured this out. My system is to interact with a third party enterprise system, and my system depends on some JAR files from third party system. So I have the "-Dloader.path" points to the directory of the third party JAR files. One of the JAR files, j2ee.jar, conflicts with tomcat. Tomcat will start if I remove j2ee.jar file from the "-Dloader.path".
Anyway, thank you again for all of your suggestions!
As Deinum suggested in the comments.
Your jar does not have the embedded tomcat dependency included in it, since you have provided the tomcat dependency scope as "runtime". Remove the scope declaration which should enable the "compile" scope by default. Your jar should then contain the dependencies required for starting the embedded tomcat container.
I have an application that uses JAX-RS annotations and spring CDI.
It works fine in tomcat (apache-tomcat-7.0.57), but in Tomee-plus (apache-tomee-plus-1.7.2) it won't run with the error:
Invalid NamespaceHandler class [org.apache.cxf.jaxrs.spring.NamespaceHandler] for namespace [http://cxf.apache.org/jaxrs]
In the tomcat version I include the cxf-rt-frontend-jaxrs and cxf-rt-transports-http jars in the .war file, whereas for the Tomee-plus version I mark those jars as provided, as tomee-plus has those already.
This is my pom (just the dependencies cause that's about all there is (this is the tomee-plus version with scope=provided):

The root cause is reported as a class not found for org.springframework.beans.factory.xml.NamespaceHandlerSupport, but I think this is misleading.
When tracing through the code I found that the error was caused by the class 'org.apache.cxf.jaxrs.spring.NamespaceHandler' not being able to be loaded because of a LinkageError.
The reason I need this is because I am trying to integrate a 3rd party lib that uses cfx and spring into an existing app.
Is this error related to class loading problems in tomee-plus, since cxf is in the tomee lib?
If I move the spring jars into the tomee-plus lib directory, it works fine, however, we want to avoid having to modify tomee at all.
Does anyone know how to get around this so that a spring/cfx app can be run in tomee-plus?
I am developing an MVC web application in java using spring framework and maven tool using Spring Tool Suite.
I am getting the following error when i am running my application.

I can't understand the error. Could anyone help me to solve the problem.
In reference to Shrikant's post - sort of.
When using Tomcat, you definitely do not want to include Tomcat's jar files in your WEB-INF/lib folder.
The jars are coming from your Maven dependencies on Spring Boot.
Specify that the spring-boot jars are provided in your pom, like so
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<scope>provided</scope>
</dependency>
This caused me a bit of aggravation, until I looked at the expanded pom's Dependency Hierarchy and saw where the tomcat jars were coming from. Once I changed the scope to provided instead of compile on the spring-boot dependencies, my pages loaded just fine.
Shrikant -> Nothing against your answer really, I just don't care to delete jars from my lib directory and then build a war, when I can just clean, package, install, and deploy all in one go, clicking one button.
I was also facing same problem, but i got the solution.
If you are using Tomcat server, then You must not put tomcat's jar files into WEB-INF/lib. Tomcat already has thoses classes, and they must be loaded by the root tomcat classloader, not by the web-app classloader.
So check your WEB-INF/lib folder and delete all the tomcat's jar.(e.g: tomcat-api-8.0.0-RC1.jar, tomcat-juli-8.0.0-RC1.jar, tomcat-util-8.0.0-RC1.jar, tomcat-servlet-api-8.0.0-RC1.jar).
instead of configuring in web.xml, use a class which implements SpringBootServletInitializer,
I trying to load Tomcat server with Spring but failing with error(see below),
i use ONLY ONE zip for spring: spring-core-3.1.1.RELEASE.jar and did very basic configuration in web.xml
Any help will be appreciated.
Thanx in advance.

Try add the spring-webmvc dependency to your pom:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>3.1.1.RELEASE</version>
</dependency>
The missing method is located in ConfigurableApplicationContext inside spring-context*.jar. So it is not possible that spring-core-3.1.1.RELEASE.jar is the only Spring JAR you have. Try adding:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
<version>3.1.1.RELEASE</version>
</dependency>
to your CLASSPATH.
