Changes in persistence.xml causes IncompatibleClassChangeError error - java

When I change my persistence.xml to a JNDI lookup a IncompatibleClassChangeError is being thrown.
This is the one that is working

The one that causes the issue is

</properties>
</persistence-unit>
</persistence>
It's not obvious to me why this is causing the issue?


Issue here was that the hibernate-entitymanager scope was not set to provided in the pom

Don't know exactly what jta-data-source should be

I tried to get Spring-MVC, Hibernate, JTA with a Postgres Server to work.
I got most of the stuff working (Read from Db through EntityManager without JTA), but I can't get the transactions to work with JTA.

If I provide my datasource from my servlet I get an Exception like
DataSourceLookupFailureException: Failed to look up JNDI DataSource with name 'dataSource'
I also found resources saying the datasource should be defined in the application-server (but I am not sure about this one). If it is important I use a Tomcat-server.

Can not find the declaration of element 'persistence'

Have put the persistence.xml in the classpath of the project in eclipse
because before the error was that the file was not found.
Now gives this error:
Caused by: javax.persistence.PersistenceException: Invalid
persistence.xml. Error parsing XML [line : -1, column : -1] :

The problem is that you mix JPA 2.0 and JPA 2.1 notation.
Either this
<persistence xmlns="http://xmlns.jcp.org/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence
http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"
version="2.1">
for JPA 2.1 or this
<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/persistence_2_0.xsd"
version="2.0">
for JPA 2 but not a mix thereof.
See http://www.oracle.com/webfolder/technetwork/jsc/xml/ns/persistence/index.html for details.

There is something slightly wrong with the XML provided, perhaps a missing version, perhaps the XML definition. Could also be a strange character or a typo somewhere.
A working template is below, try that instead.
<?xml version="1.0" encoding="UTF-8"?>
<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/persistence_2_0.xsd"
version="2.0">
....
</persistence>

I have faced similar problem (Cannot find the declaration of element 'entity-mappings') in the past when I had persistence.xml with JPA version 2.0 & orm.xml file with version 2.1. I think the error reported above are similar.
Working samples for JPA 2. Read the sample below carefully and note their version. Ensure they are of same versions as in the samples. You may use JPA 2.1 and approprite schema reference as well.
persistence.xml
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<class>org.sanjus.pa.ejb.entity.UserEntity</class>
</persistence-unit>
</persistence>
orm.xml
<entity-mappings xmlns="http://java.sun.com/xml/ns/persistence/orm" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm orm_2_0.xsd" version="2.0">
<named-query name="findUserJSONById">
<query>SELECT a.userJson FROM UserEntity a WHERE a.userId = :userId</query>
</named-query>
</entity-mappings>

Solved!
I do not know exactly what was wrong, but it worked well:

Hibernate/JPA not validating against DB schema on startup

For some reason hibernate is not catching issues like mapping entities to tables that do not exist. My persistence.xml file looks like this...

Try adding the property "hibernate.hbm2ddl.auto" with value of "validate":
<property name="hibernate.hbm2ddl.auto" value="validate"/>
