或者

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in ServletContext resource [/WEB-INF/classes/applicationContext.xml]: Invocation of init method failed; nested exception is javax.naming.NoInitialContextException: Cannot instantiate class: org.ow2.carol.jndi.spi.MultiOrbInitialContextFactory [Root exception is java.lang.ClassNotFoundException: org.ow2.carol.jndi.spi.MultiOrbInitialContextFactory]

错误

是因为WAS容器和应用中jta.jar报冲突，删除应用中的jta.jar并从WAS卸载所有应用，重启WAS，重新这些没有包含jta.jar的新应用就可以。
