Sebastien Arbogast updated SPRING-69:
-------------------------------------
Attachment: OpenSessionInViewFilterForAndromda.java
Of course package and class names are just propositions and should be adapted...
> Adapting OpenSessionInViewFilter to AndroMDA
> --------------------------------------------
>
> Key: SPRING-69
> URL: http://jira.andromda.org/browse/SPRING-69
> Project: Spring Cartridge
> Type: New Feature
> Environment: Web application on Tomcat servlet container
> Reporter: Sebastien Arbogast
> Assignee: Chad Brandon
> Attachments: OpenSessionInViewFilterForAndromda.java
>
> To prevent the common "lazy loading" bug in the web tier, Spring framework
> provides a utility servlet filter : OpenSessionInViewFilter. Unfortunately
> this filter is not very flexible and it looks for the sessionFactory bean
> directly in root application context whereas in the structure of Spring
> configuration files generated by AndroMDA, it's one level down in
> applicationContext.xml
> So with the default configuration of OpenSessionInViewFilter in web.xml, web
> application initialization works fine but on the first filtered request, you
> get an internal server error caused by a NoSuchBeanException on
> sessionFactory.
> To solve this problem I propose to add a new class in Spring cartridge
> generated files : OpenSessionInViewFilterForAndromda, which extends Spring
> OpenSessionInViewFilter and overrides lookupSessionFactory for taking our
> particular structure into account (see attachment).
> Then the only thing the user would have to do is to change the class for
> OpenSessionInViewFilter filter in web.xml and everything should work fine.
