you have same problem described in this question, means have 2 entitymanager beans - causing confusion.
basically need remove the
<import resource="classpath:applicationcontext.xml"/> from web-application-context.ml, partition beans such web-tier , application beans in separate context files , make sure component scan in each picks correct beans. might require moving classes different packages, difficult advise without more information structure of project.
finally reference both contexts web.xml
