Error creating bean with name 'entityManagerFactory' -> Cannot parse persistence unit from class path resource [META-INF/persistence.xml]

Question

I have this problem in my j2e application and I can't find any solution. Build was successful but there is thrown runtime exception. I tried many advices from google but nothing can solve my problem.

SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in ServletContext resource [/WEB-INF/datasource-config.xml]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Cannot parse persistence unit from class path resource [META-INF/persistence.xml]

Stack trace shows some problem with persistence.xml file. The persistence XML should start with tag. Can you verify that? — Phani, Jul 23 '13 at 20:23
yes, if there was this error it should be found before running app....build was successful — lukas, Jul 23 '13 at 20:27
There is some problem with persistence unit, which version of persistence are you using? — Phani, Jul 23 '13 at 20:33

Firstly, java compiler will not validate the existence of persistence.xml during compile time. The error only happen at runtime.

Stack trace you're getting is pretty clear, your program could not locate persistence.xml on classpath.

The location of persistence.xml within your jar has to be: META-INF/persistence.xml, or if it's war: WEB-INF/classes/META-INF/persistence.xml

Thanks, I have war and I added resource to build path with target as you wrote. – lukas Jul 25 '13 at 18:30
Even though old, I think this is relevant. When working with Maven and JPA 2, running `mvn clean install` will often run tests which may reference `src/test/resources`. Check any context configuration in that location which may reference an invalid `EntityManagerFactoryBean` bean configuration. – Rai Aug 23 '14 at 20:00

I've had similar problem, but in my xml-file I've had correct path to persistence.xml. Problem was in that relations between my entities was wrong. Also I've had wrong import for date (I used Spring Data JPA which doesn't use sql.Date)

1)Please check your datasource class it says oracle.jdbc.pool.OracleDataSource

2)Check your db details- username, password, driver URL

If the above details are correct.

3)Create a database in the back-end and try to refer it. And make sure all your tables and entities that your code is referring, are present.

4)clean your tomcat(web server) and try to restart your application

I had the same issue. Resolved it using the above steps. Hope this helps !!!
