java - Spring, JPA, Hibernate, Tomcat: Unable to find persistence unit when loading Spring application context -

i have application context trying setup jpa:

application-context.xml:

persistence.xml:

<persistence-unit name="pu1" transaction-type="resource_local">     <provider>org.hibernate.ejb.hibernatepersistence</provider>     <class>com.myapp.model.address</class>     <class>com.myapp.model.agressofile</class>     <class>com.myapp.model.customergroup</class>     ... </persistence-unit>  <persistence-unit name="pu2" transaction-type="resource_local">     <provider>org.hibernate.ejb.hibernatepersistence</provider>     <class>com.myapp.model.competencearea</class>     <class>com.myapp.model.competenceareacategory</class>     ... </persistence-unit> 

i loading application context in web.xml way:

<context-param>     <param-name>contextconfiglocation</param-name>     <param-value>         /web-inf/spring/application-context.xml     </param-value> </context-param>  <listener>     <listener-class>org.springframework.web.context.contextloaderlistener</listener-class> </listener> 

competenceareamanager class locates in scanned package "com.myapp.model.manager" has following content:

@service public class competenceareamanager {      @persistenceunit(unitname = "pu2")     private entitymanagerfactory entitymanagerfactory;      @suppresswarnings("unchecked")     public list<competencearea> getcompetenceareas() {         list<competencearea> competencearealist = null;         entitymanager em = entitymanagerfactory.createentitymanager();         query q = em.createnamedquery(competencearea.find_all);         competencearealist = q.getresultlist();         return competencearealist;     }      public void setentitymanagerfactory(entitymanagerfactory entitymanagerfactory) {         this.entitymanagerfactory = entitymanagerfactory;     } } 

however, when try run application in tomcat 7.0, following error:

any idea i'm doing wrong?

if configure persistenceannotationbeanpostprocessor persistenceunits, informing persistenceannotationbeanpostprocessor pus come jndi (as javadoc setpersistenceunits() methods mentions it). stack trace shows failing jndi lookup.

since using <context:annotation-config/> in application-context.xml, don't need declare persistenceannotationbeanpostprocessor, because 1 automatically registered, looks pus reading meta-inf/persistence.xml files located in classpath, expect.

your configuration should simple :

persistence.xml remains unchanged

competenceareamanager

as sergey makarov mentions it, inject entitymanager @persistencecontext instead of injecting entitymanagerfactory @persistenceunit. em transactional (thus bound thread, ensuring thread-safety dao), , can still configure @persistencecontext unitname in order specify pu em has bound to.

application-context.xml

just drop declaration of persistenceannotationbeanpostprocessor bean. rest of file remains unchanged.

i haven't tried particular config (2 pus), configuration mention 1 have been using, success.
