OpenEntityManagerInViewFilter Problems

Question

I have scoured this site among others for answers in getting OpenEntityManagerInViewFilter to work. I have a standard User object that references a roles object with a many

But now!!

Let me make a guess: the name of your application is: board?

Correct? then go on and read the remaining answer!

Yes you have two entity manager, and even two identical application contexts (one app context and one web context) -- So you have every bean twice!

What happened is: you have only one (relevant) spring configuration file: 'board-servlet.xml' ('persistence-spring-beans.xml' is included in that file so at least it is one big logical file)

And you create a context from this file twice in the 'web.xml':

first:

    contextConfigLocation
    
        /WEB-INF/board-servlet.xml  *****This file references the file with entityManager declared*****
        /WEB-INF/board-security.xml
    

...

    org.springframework.web.context.ContextLoaderListener

ContextLoaderListener load the application context specified by the files in 'contextConfigLocation' parameter.

second:

    board
    org.springframework.web.servlet.DispatcherServlet
    1

Dispatcher Servlet create the web application context, which xml file is:

• named by the init-param 'contextConfigLocation'
• or, if there is no such paramter, it looks for an file named '/WEB-INF/-servlet.xml'

(For more details have a look at the Java Doc of FrameworkServlet)

In your case there is no explicitly named file, so it reads the 'board-servlet.xml' again.

What you need to do is separate them:

• remove the from board-servlet.xml
• change the contextConfigLocation in web.xml that it refers to classpath:persistence-spring-beans.xml and /WEB-INF/board-security.xml direcly
• (not 100% necessary) separate the 'context:component-scan' so that a component scan in board-servlet.xml scan only for @Controller and the component scan in persistence-spring-beans.xml scan for the others (@Service, @Component, @Repository and @Dao)
• last step: please tell me that it works now
