I am using Spring 3.1.1 in my application. I have integrated JPA and Hibernate 4.0.1 into it.
My entityManagerFactory and few more beans are not getting instantiated.

I am not supposed to use Maven, so i am adding jars directly to class path.
The Jars inside class path are:
My persistance.xml is inside META-INF, and the code inside is:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" 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">
<persistence-unit name="03offileLogger">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<class>com.comviva.mfs.eig.persistance.jpa.entities.TransactionLog</class>
</persistence-unit>
</persistence>
The appendContext.xml
is my application Context file used for configuring spring beans which contains the following code:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"

</bean>
</property>
</bean>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
</bean>
</beans>
The errors pasted above are cut to fit the size, But after each error it is saying
Invocation of init method failed;
Initialization of bean failed;
I read it somewhere that there is some version conflict, so the entityManagerFactory is not being instantiated.
Update: The code below shows my entity (only one table).

Replace the Hibernate jars present in the Mule server,
i.e:location sample: C:\dev\AnypointStudio\plugins\org.mule.tooling.server.3.5.2.ee_4.1.0.201410031231\mule\lib\opt
.
Reason: If you have developed your app with specific version of Hibernate, then you need to have the same version in the mule server because while you running your app in the mule server it uses its own copy of it.

The error message 'java.lang.NoSuchMethodError: org.hibernate.cfg.Environment.verifyProperties" means you do have a different version of class org.hibernate.cfg.Environment
Your error log says you are using mule. Mule comes with its own hibernate jar. Please check the lib directory of mule to confirm that you don't have a conflicting hibernate jars.

Do you have any Entities, relationships defined? Can you take thise out and let just EntityManager initialize?
The reason is simple, I think I saw this kind of errors when there was a problem with my Entities and relations
