Datasource com Jetty

Programação Java
#1

Pessoal,

Estou tentando subir minha app com jetty e está dando o seguinte erro:

GRAVE: Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘entityManagerFactory’ defined in class path resource [appServiceContext.xml]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: TestePercistenceUnit] Unable to build EntityManagerFactory
at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1488)
at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:524)

Segue meu jetty-env:

<?xml version="1.0" encoding="UTF-8"?> jdbc/TesteDS thin jdbc:oracle:thin:@localhost:1521:XE teste teste true MinLimit 5

Alguém pode me ajudar?
