The import javax persistence cannot be resolved

Question

I m currently working on a project that requires EntityManager EntityManagerFacotry and Persistence each from the javax persistence package   It seems to be for the database service  but the current code is not very well documented   By searching google it seems that there should be an xml file that comes along with this  but there isn t one of those either   I guess my question is simply how do I make these unresolved imports go away   Do I have to add another jar to the build path   It seems that I shouldn t have to since it s been around since 1 5   Any help is greatly appreciated

hibernate-distribution-3 6 10 Final lib jpa   Add this jar to solve the issue  It is present in lib folder inside that you have a folder called jpa ---  inside that you have hibernate-jpa-2 0-1 0 1 Final jar

If you are using Hibernate as a JPA implementation and you are not using Maven Gradle  the easier way is to download whole bundle instead of jar file one by one   Go http   hibernate org orm downloads  and download the latest library  extract the jar from the required folder

I ran into this same issue and realized that  since I am using spring boot  all I needed to do to resolve the issue was to add the following dependency        lt dependency gt           lt groupId gt org springframework boot lt  groupId gt           lt artifactId gt spring-boot-starter-data-jpa lt  artifactId gt       lt  dependency gt

I solved the problem by adding the following dependency   lt dependency gt       lt groupId gt javax persistence lt  groupId gt       lt artifactId gt persistence-api lt  artifactId gt       lt version gt 2 2 lt  version gt   lt  dependency gt    Together with    lt dependency gt       lt groupId gt org springframework boot lt  groupId gt       lt artifactId gt spring-boot-starter-data-jdbc lt  artifactId gt   lt  dependency gt

Yes  you will likely need to add another jar or dependency  javax persistence   is part of the Java Persistence API  JPA   It is only an API  you can think of it as similar to an interface  There are many implementations of JPA and this answer gives a very good elaboration of each  as well as which to use   If your javax persistence   import cannot be resolved  you will need to provide the jar that implements JPA  You can do that either by manually downloading it  and adding it to your project  or by adding a declaration to a dependency management tool  for eg  Ivy Maven Gradle   See here for the EclipseLink implementation  the reference implementation  on Maven repo    After doing that  your imports should be resolved   Also see here for what is JPA about  The xml you are referring to could be persistence xml  which is explained on page 3 of the link   That being said  you might just be pointing to the wrong target runtime  If i recall correctly  you don t need to provide a JPA implementation if you are deploying it into a JavaEE app server like JBoss  See here  Note that you typically don t need it when you deploy your application in a Java EE 6 application server  like JBoss AS 6 for example     Try changing your project s target runtime   If your local project was setup to point to Tomcat while your remote repo assumes a JavaEE server  this could be the case  See here for the difference between Tomcat and JBoss   Edit  I changed my project to point to GlassFish instead of Tomcat and javax persistence   resolved fine without any explicit JPA dependency

If anyone is using Maven  you ll need to add the dependency in the POM XML file  The latest version as of this post is below    lt dependency gt       lt groupId gt org hibernate javax persistence lt  groupId gt       lt artifactId gt hibernate-jpa-2 1-api lt  artifactId gt       lt version gt 1 0 0 Final lt  version gt   lt  dependency gt

In newer hibernate jars  you can find the required jpa file under  hibernate-search-5 8 0 Final dist lib provided hibernate-jpa-2 1-api-1 0 0 Final   You have to add this jar file into your project java build path  This will most probably solve the issue

My solution was to select the maven profiles I had defined in my pom xml in which I had declared the hibernate dependencies   CTRL   ALT   P in eclipse   In my project I was experiencing this problem and many others because in my pom I have different profiles for supporting Glassfish 3  Glassfish 4 and also WildFly so I have differet versions of Hibernate per container as well as different Java compilation targets and so on  Selecting the active maven profiles resolved my issue
