I am using Windows 10 and Netbeans 8.2. I am able to use JPA 2 with Hibenate 4.3.x. Actually Netbeans 8.2 comes with Hibernate 4.3.x. Now i want to use Hibernate 5.2.x. I have downloaded Hibernate 5.2.12 as zip file from this link http://hibernate.org/orm/releases/5.2/. Then i have imported it into Netbeans. But i am getting the error :
javax.persistence.PersistenceException: No Persistence provider for EntityManager.
I know it is easy to use with maven.
Finally i have got the solution.
If the zip folder unzipped and all the jars inside the required folder imported, it will not work. One of the following errors or both may shown :
No Persistence provider for EntityManager named
Hibernate 5.2.2: No Persistence provider for EntityManager
To solve the above problems have to do the following task :
This line have to add in the persistence.xml file :
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
And have to download classmate-0.8.0.jar, and have to add it in the class path. This jar can be downloaded from Here
Then have to download the hibernate-entitymanager-5.0.12.Final.jar file and Have to add it in the class path. The jar can be downloaded from Here
In the Netbeans there is a default library called Hibernate 4.3.x(JPA 2.1).If you want to change this library, you have to find the installation folder of Neatbeans and the folder where hibernate has kept.
In windows it may found in :
C:\Program Files\NetBeans 8.2\java\modules\ext\hibernate4
For Linux it may be found in :
/usr/local/netbeans-8.2/java/modules/ext/hibernate4/
Then paste the jars from required folder (It will be found in downloaded Hibernate folder) and other jars mentioned above. You may find some jars duplicate. Then you may notice that some jars of hibernate almost with the same name but difference in version. Then delete the jars which has older version name.
one of your dependency file is Zip file . Extract it and the add the Jar instead

I'm learning Hibernate and am following an online tutorial on integrating it with Eclipse. I have installed the JBoss plugin with Hibernate into Eclipse Luna 4.4. and verified I have Hibernate available. The next step is to configure the build path for my new Java project and include the "necessary" Hibernate libraries...no information given on how to do that. How does one go about identifying the required jar files? I see several folders under my eclipse plugins directory that contain jboss or hibernate in the folder name, and underneath these folders do exist jar files, but I would think that there must be an easier way than plodding through all these directories and adding any jar file that looks like it's related to Hibernate or JBoss. Thanks.
I am starting working on my first JPA project and I will be using Hibernate. I have downloaded the hibernate-release-4.3.9.Final.zip file from http://hibernate.org/orm/downloads/ website which mentions that Hibernate 4.3.9.Final version supports JPA 2.1.
I have unzip this file and there are 35 Jar files in it. These are the locations of those 35 Jars:
1 Jar in lib\envers folder.
1 Jar in lib\jpa folder.
1 Jar in lib\jpa-metamodel-generator folder.
3 Jars in lib\optional\c3p0 folder.
3 Jars in lib\optional\ehcache folder.
9 Jars in lib\optional\infinispan folder.
2 Jars in lib\optional\proxool folder.
3 Jars in lib\osgi folder.
10 Jars in lib\required folder.
1 Jar in project\gradle\wrapper folder.
1 Jar in project\hibernate-osgi\src\test\resources\bnd folder.
My question is which Hibernate Jars are needed for JPA 2.1 support? I am sure that 1 Jar in lib\jpa folder is definitely needed. But what other Jars are needed?
Thanks
For Hibernate core with JPA 2.1 support the jars in required folder are alone enough:
From the maven repository :
The other jars as said are optional and can be added to the classpath on a need basis.For instance you want caching and want to use ehcache as your cache provider, then you can add ehcache jar to the classpath. Or c3p0 for connection pooling.
If you just need JPA with hibernate's implementation , then you need to have the following in your classpath:

I have my little project for persistence in Tomcat (with Hibernate and Postgres). It's not an EJB project.
I inserted the file "persistence.xml" in the "src" folder of the project: goes well there? I have to copy it in some folder of Tomcat? Should I put the Hibernate libraries inside the "lib" folder of Tomcat?
I have read on the site of Postgres that for Tomcat 4 and 5 should be modified the "server.xml" file, inserting a listing that they give, but they don't specify whether the procedure also applies to Tomcat 6. What do you think about?
Right now, My project framework is Hibernate 3.6.5 now want to upgrade it to the latest one Hibernate 4.3.5.
There are some dependencies in between the .jar files.
My question is :
What all are the .jar files need to be change/replace at the time of upgrade ?
Recently I have the following .jar files for the Hibernate 3.6.5.
Here is the recent required .jars for the Hibernate 4.3.5.
Which .jar files are need to be replace ?
Thanks.
Download the latest version of Hibernate from the following Site http://hibernate.org/.
After downloading unzip the Downloaded Zip file. Now you can see mainly three folders like documentation, lib, project.
Open lib folder, now you can see following folders envers, jpa, optional, osgi, required.
Add all jar files (under required folder) to the classpath and also add one more jar file (under jpa).
===============================================
Assume you are downloaded Hibernate Software following location.
Hibernate_HOME = /home/rangareddy/Hibernate/hibernate-release-4.2.7.Final
Jar files:
%Hibernate_HOME%/lib/required/antlr-2.7.7.jar
%Hibernate_HOME%/lib/required/dom4j-1.6.1.jar
%Hibernate_HOME%/lib/required/hibernate-commons-annotations-4.0.2.Final.jar
%Hibernate_HOME%/lib/required/hibernate-core-4.2.7.Final.jar
%Hibernate_HOME%/lib/required/hibernate-jpa-2.0-api-1.0.1.Final.jar
%Hibernate_HOME%/lib/required/javassist-3.18.1-GA.jar
%Hibernate_HOME%/lib/required/jboss-logging-3.1.0.GA.jar
%Hibernate_HOME%/lib/required/jboss-transaction-api_1.1_spec-1.0.1.Final.jar
%Hibernate_HOME%/lib/jpa/hibernate-entitymanager-4.2.7.Final.jar
there is an error in all my javax header file "package javax. does not exist" here is an image.
Try to add the library Persistence (JPA 2.1) in your folder Libraries.
To do this: Left-click Libraries->Add Library...->select Persistence (JPA 2.1)
Download one of the jar file from the following link and store it in your local machine :
http://www.jarfinder.com/index.php/java/info/javax.obex.Operation
Now follow the given steps in the following link to add that jar file into your project.

This should resolved your errors.
Netbeans 6.9.1 already has Java ME SDK 3.0. Just check the Emulator Platform in the properties of your application. If there is no emulator platform just download the sun java toolkit or Java ME SDK 3.0 and then integrate with Java platform on your netbeans IDE.
It is easy, I was facing the same issue and fixed in this way:
File -> New File -> Persistence -> New Persistence UNIT
Here you need to select your desire package from drowpdown list and click ok.
It will add EclipsLink in library folder which has the package javax.
The error message says: package javax.obex does not exist. This means you are missing a library (JAR file). Add the JAR file to your project. In Eclipse you can do that by right-clicking the project, selecting Properties, then Java Build Path, Libraries. Click "Add JARs" or "Add External JARs" to add the relevant JAR file to your project.
This JAR file most likely has something to do with bluetooth. You can download an interface JAR from here, but you most likely need an implementation JAR also.
You probably don't have the project libraries properly setup: it looks like you have added the source jar file to your project, not the jar with actual class files.
