Question

So i Have this problem in implementing JPA and Hibernate in Spring WS.
I have configured everything correctly and according to tutorial it should work – but it is not.

Problem lies in persistance.xml, here it is how it looks:

<persistence xmlns="http://java.sun.com/xml/ns/persistence" 
                xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                xsi:schemaLocation="http://java.sun.com/xml/ns/persistence 
                http://java.sun.com/xml/ns/persistence/persistance_1_0.xsd"
            version="1.0">

    <persistence-unit name="hibernatePersistenceUnit" transaction-type="RESOURCE_LOCAL">
        <properties>
            <property name="hibernate.hbm2ddl.auto" value="none" />
        </properties>
    </persistence-unit>
</persistence>

and the exception i am getting:

Caused by: java.io.FileNotFoundException: class path resource [persistence_1_0.xsd] cannot be resolved to URL because it does not exist
    at org.springframework.core.io.ClassPathResource.getURL(ClassPathResource.java:177)
    at org.springframework.orm.jpa.PersistenceUnitReader.validateResource(PersistenceUnitReader.java:281)
    at org.springframework.orm.jpa.PersistenceUnitReader.readPersistenceUnitInfos(PersistenceUnitReader.java:108)
    ... 57 more

I am struggling with this since a while… Do anyone have an idea what am i missing?

Answer 1

You need to include appropriate jar file containing the persistence_1_0.xsd.

This is explained here.

what is the use of xsi:schemaLocation?
