java.lang.NoClassDefFoundError: javax/persistence/TableGenerators

Im trying to develop a BackEnd app using hibernate JPA into Tomcat.
From now it was working fine at test with JPA functionality and a 1st version without the JPA's services is working right now (file uploads, downloads and this stuff).
Now I'm in my way to integrate the JPA to apply all the functions we need but, even when all test work fine (including service tests), im getting the following 500 error when I submit the request from Postman to the local server.
This is the exception:
javax.servlet.ServletException: org.glassfish.jersey.server.ContainerException: java.lang.NoClassDefFoundError: javax/persistence/TableGenerators
This is my pom.xml

And the exception triggers during the generation of the Entity Manager
em = Persistence.createEntityManagerFactory("testDb").createEntityManager();
JDBC driver is also registred before the instance of the eEntity Manager
try {
Class.forName("com.mysql.cj.jdbc.Driver");
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
I'm also using the pluging enforce to check if any dependency is creating any version incompatibility in my pom.xml.
This is the first project i have to configure from 0 and this question is my last resource to solve the problem i have.
Thanks you all :D

In most situations, this error says that the classloader cannot find the class your code depends on.
In your case the class named javax/persistence/TableGenerators expected to be on the classpath, but for some reasons it's not.
The TableGenerators class is packaged within javax.persistence-api-2.2.jar file.
Before deploying your .war file on tomacat, check whether the requierd jars on the classpath - enter into your RESTfullApp.war file and look at the WEB-INF/lib folder, the javax.persistence-api-2.2.jar must be there, otherwise fix your maven build in order to achieve this.
UPDATE
It also worth to mention, that exploded .war folder in Tomcat ($CATALINA_BASE/webapps/RESTfullApp) must have the same layout and contain the same set of files you see in
your .war archive, check the javax.persistence-api-2.2.jar is also there.
In case the mentioned .jar are present on the classpath, I would also suggest you checking the javax.persistence-api-2.2.jar is not broken.
Sometimes, it happens to be maven downloads broken .jar archives which might cause the error you see.
At least, you can try to unzip this jar file and check if there will be any errors while extracting this jar.

Bad news... The current config I'd display works properly in the server. That probably means the problem I'm getting is from a problem between Tomcatn and Windows. For now the test are returning a 404 code (the catch exit of the code) but now all is about working in the service and make some tests before publishing the service. Any way, thanks for the help.

Weird ClassCastException while deploying WAR to WildFly 11

I am facing a weird issue: when I deploy my WAR file on WildFly I get the following error:
[2017-11-27 01:15:17,777] Artifact JSFDemo:war: Artifact is being deployed, please wait...
Connected to server
[2017-11-27 01:15:18,427] Artifact JSFDemo:war: Error during artifact deployment. See server log for details.
[2017-11-27 01:15:18,428] Artifact JSFDemo:war: java.lang.Exception: {"WFLYCTL0080: Failed services" => {"jboss.persistenceunit.\"JSFDemo.war#demo_unit\"" => "java.lang.ClassCastException: org.dom4j.DocumentFactory cannot be cast to org.dom4j.DocumentFactory
Caused by: java.lang.ClassCastException: org.dom4j.DocumentFactory cannot be cast to org.dom4j.DocumentFactory"}}
I believe the problem is related to one of my dependencies. WAR is built on POM file with depedencies inherited from the parent one which is shown below.

The reason you get this error is because you have the class org.dom4j.DocumentFactory loaded from two different classloaders.
Most likely it is provided in WildFly and you packaged it in a JAR in the lib-directory of your WAR file. So look into the WAR and change your POM until it is not included anymore.
To find out why it is included, mvn dependency:tree within your war-module can help.
If you can't figure it out from looking at the WAR-file, set logging of the category org.jboss.modules to TRACE and search the logfile which classloaders load the class org.dom4j.DocumentFactory.

Missing org.javabuilders.event package in Maven Project

I recently took over a Java Maven project that has been in the works for a couple of years. I am trying to clean up the project and make it easy to set-up for new developers and I am having trouble building one of the many modules. This module spit out the following error:

Does anyone know where I can find this package or a package that contains the same class? I have looked on search.maven.org and all over the internet, but cannot find anything that works. Any help would be greatly appreciated. :)

Add the following dependency to your pom:
<!-- https://mvnrepository.com/artifact/com.kenai.swingjavabuilderext/javabuilder-core -->
<dependency>
<groupId>com.kenai.swingjavabuilderext</groupId>
<artifactId>javabuilder-core</artifactId>
<version>0.3</version>
</dependency>

I was able to find the package I was looking for. A previous employee who worked on the project had a Nexus repo containing the package. As far as I understand it is a very old package that is not really used anymore. That is why it is not easily found online.
Thanks for the help everyone!!

Spring MVC Maven Modules

Let's say that I want to have 3 maven modules:
parent
login
webapp
I want to have Java classes & jsp files in both modules (login & webapp). My workaround partially works, it builds one WAR file, web pages are rendered, looks fine, but when I try to use API (interfaces from login module) in webapp module - classes can not be found. I think that something is wrong with POM files.
POMs are almost the same, the main difference between login & webapp poms - that webapp has dependency with login.
POM source from webapp module:

By what you described you should consider maven overlays.
An overlay of a WAR file, is simply a Maven project that uses another
project's WAR output as a dependency, rather than a project's JAR.
When the overlay project is built, the underlying project's WAR file
is exploded and files in the overlay project added to it. If an
overlay project has a file with the same path and name as a file in
the underlying WAR it will replace it.
You would include the war from one module in the same way as you do now, and override the files (either classes or static resources) in your current module. A blog that explains more, and a step-by-step guide.

Conflict with Maven Dependencies (Spring & Hibernate)

After trying to integrate Hibernate with Spring in my current project, I finally got my class structure and stuff ready, but now I have a problem with running my web app (Spring MVC).
When I go through the registration process on the web application, I get this exception as soon as I press "Register Now":
java.lang.NoSuchMethodError: org.hibernate.SessionFactory.openSession()Lorg/hibernate/classic/Session;
I already used Google to find out what could cause that exception and I came to the conclusion, that it could be my pom.xml with a dependency conflict in it. Furthermore, I used the graphical dependency tree in IntelliJ IDEA 13.1 Ultimate to fix that problem, but it doesn't show any conflicts.
Here's my pom.xml:

I would really appreciate if you could tell me whether my problem is caused by the pom.xml and if yes, what I have to change to fix it and if no, which other causes are possible.
Thanks in advance!

Your error indicates that your code is not recompiled after change in dependencies.
Just perform Maven update dependencies and then run mvn clean install and redeploy your artifacts.

So, just to make this thing clear, I was using the (as I now know) deprecated and no longer supported HibernateTemplate thing from Spring ORM. After switching to manual transactions with the SessionFactory, everything works perfect.
