[FIXED] INFO: HHH000318: Could not find any META-INF/persistence.xml file in the classpath, despite file being present

Issue

Here is how my project structure looks:

When I right-click project and add a persistence unit, the percistence.xml is added in "Configuration Files". I Copied percistence.xml after getting this exception to "Web Pages/META-INF" and the same exception was thrown. I tried deleting percistence.xml from "Configuration Files" and the same exception was thrown also This is what the properties in my percistence.xml looks like:

<persistence-unit name="PU" transaction-type="RESOURCE_LOCAL">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties>
  <property name="javax.persistence.jdbc.url" value="jdbc:sqlserver://ramysazure.database.windows.net:1433;databaseName=SocialDB"/>
  <property name="javax.persistence.jdbc.user" value="HI1033@ramysazure"/>
  <property name="javax.persistence.jdbc.driver" value="com.microsoft.sqlserver.jdbc.SQLServerDriver"/>
  <property name="javax.persistence.jdbc.password" value="******"/>
  <property name="hibernate.cache.provider_class" value="org.hibernate.cache.NoCacheProvider"/>
</properties>

Solution

Move the META-INF directory to your Source Packages or even resources. You will typically have the structure of src/main/java for your sources, and the resources will be in src/main/resources. That directory is for files that will be copied to the build destination and not processed.

Keep the WEB-INF where it is, though.
