JPA persistence XML file location

Traditionally, the persistence.xml is located in a META-INF folder that needs to reside in the root of the Java classpath. If you’re using Maven, you can store it in the resources folder, like this:

src/main/resources/META-INF/persistence.xml

persistence.xml should be put inside an directory called META-INF under the root of the classpath .

Right click your project in eclipse ==> Properties ==> Java Build Path . Suppose you configure one of the build paths to be /src/main/resources , then you should put the persistence.xml at /src/main/resources/META-INF/persistence.xml
