Missing artifact org.hibernate:hibernate-entitymanager:jar:4.3.6.FINAL

**[> I am having a spring MVC project where I want to integrate Hibernate, however when I am adding Hibernate dependencies to POM.xml
file it showing error "Missing artifact
org.hibernate:hibernate-entitymanager:jar:4.3.6.FINAL" and the jar
dependency is not getting resollved. Same thing is happening with the
jdbc14 jar
I tried different versions of the jar but still the issue persists.][1]**

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.

I have tried making hibernate-core scope provided and exclude dom4j from it. What is the exact workaround with my POM structure?

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.

What is the meaning of "The package is inside a non-bundle dependency" warning in a Maven project?

I encountered the warning when I imported my Maven project in IntelliJ:
The package 'org.xml.sax' is inside a non-bundle dependency
There are, in fact, 3 packages causing this: org.xml.sax, javax.servlet, and javax.xml.parsers. I have checked pom.xml and these packages weren't there except for javax.servlet.
Do I need to add the missing packages to the pom.xml? The program works but it would be better to get rid of this warning. I would also like to know if there are any expected problems when this warning is present.
This is the project's pom.xml

I have checked a lot of threads discussing similar issues (sample) but none of the fixes provided are able to solve my issue. I included nearly all the dependencies but none worked.
Please help

issue was fixed once i removed optional from geronimo
i am able to run a GAE application with JPA :)

Maven/GAE - Missing some Datanucleus classes

I have been struggling for hours trying to figure the good pom.xml out for my already existing GAE/J project.

I changed the version of datanucleus-core so that OMFContent could be found but then it fails even more badly.
Any idea how to solve this?
