Spring Entitymanager java.lang.ClassFormatError - spring

Question

This is 2nd day that I am struggling with this issue.
We have a web app that uses spring and hibernate. Now We are trying to expose some functionality to command line. So We should be able to run a class from command line(without web app) so it should have access to spring and hibernate.
<context:annotation-config/>
<context:component-scan base-package="com.x.y.z"/>
<jpa:repositories base-package="com.x.y" />
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean">
<property name="jpaProperties">
<props>
<prop key="javax.persistence.validation.mode">NONE</prop>
<prop key="hibernate.validator.apply_to_ddl">false</prop>
<prop key="hibernate.validator.autoregister_listeners">false</prop>
<prop key="hibernate.format_sql">false</prop>
</props>
</property>
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="generateDdl" value="false" />
<property name="database" value="SQL_SERVER" />
<property name="showSql" value="false" />
</bean>
</property>
</bean>
Here I am using LocalEntityManagerFactoryBean but it seems there is no way to set datasource to it. It gets from persistance.xml
If I use LocalContainerEntityManagerFactoryBean I can set datasource(it has datasource property)
persistance.xml:
<persistence version="1.0" 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_1_0.xsd">
<persistence-unit name="oms-jpa">
<class>com.domain.User</class>
</persistence-unit>
In persistance.xml I am not defining any database informaton for datasource, so LocalEntityManagerFactoryBean does not work for this.
what I am getting:
Error creating bean with name 'entityManagerFactory' defined in file [C:\Users\ekamoliddinov\IdeaProjects\web\conf\spring-config.xml]: Invocation of init method failed; nested exception is java.lang.ClassFormatError: Absent Code attribute in method that is not native or abstract in class file javax/validation/Validation
googled then some says:
Jar versions messed up
jee-api.jar is missing
But I have jee-api.jar.
My questions:
What is causing the above exception?
Can I use LocalContainerEntityManagerFactoryBean without having web
container? Spec does not say anything about this.
If i can not use LocalContainerEntityManagerFactoryBean then how can I set up
LocalEntityManagerFactoryBean so it should use my datasource not from
persistance.xml(I can not define anything in persistance.xml).
I am using spring version 3.1.3 with hibernate 4.1.8.Final and i am in command line(I do no have jee environment)
Sorry about more than one questions, but all questions are arising from the same root I think.
Any help will be appreciated.
Thanks.

Answer 1

After trying 3 days I fixed the issue. The jars where messed up :)
It was because I have jee-api.jar in my classpath and I was running the code from command line, I had not web env. So there was not any impl of jee-api.jar in my env. That is why it was giving the above exception. I removed jee-api.jar and disappeared.
Another thing That I can tell: we can use LocalContainerEntityManagerFactoryBean from command line. I am using it.
The last thing: We can not set datasource to LocalEntityManagerFactoryBean
This my help to someone.
