My application of OEIV Filter doesn't seem to be getting applied to my Struts actions. I am using Spring 3, Spring Security 3, Struts2, Tiles2 and JPA backed by Hibernate 3. When I try to access a collection for an entity in a struts action, unless the Entity has a fetch type of eager, I am getting a JPA LazyInitializationException. I see the filter in the stack trace, but can't figure out why it's not being applied. Can anyone help with this? Here's my web.xml filters and filter mappings: <pre><code>  <filter> <filter-name>Spring OpenEntityManagerInViewFilter</filter-name> <filter-class>org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter</filter-class> </filter> <filter> <filter-name>springSecurityFilterChain</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> </filter> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class> </filter>  <filter-mapping> <filter-name>Spring OpenEntityManagerInViewFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <filter-mapping> <filter-name>springSecurityFilterChain</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </code></pre> My Entity: <pre><code>@Entity @Table(name = "DEALER") public class Dealer implements Serializable { private static final long serialVersionUID = -1831628098752177382L; @Id @Basic(optional = false) @Column(name = "DEALER_ID") private Integer id; @Basic(optional = false) @Column(name = "NAME") private String name; ... @OneToMany(cascade = CascadeType.ALL, mappedBy = "dealer") private Set<InventoryPart> inventoryParts; ..getter/setter methods ommitted for brevity } </code></pre> The Struts 2 Action causing the error... <pre><code>public class DealerAction extends BaseStrutsAction implements ModelDriven<Dealer>, Preparable { public void prepare() throws Exception { PermissionedUser user= getAuthenticatedUser(); if(user != null){ dealer= user.getDealer(); if(dealer != null){ dealerId= dealer.getId(); } } } ... public List<InventoryPart> getInventoryParts() { inventoryParts= new ArrayList<InventoryPart>(dealer.getInventoryParts()); return inventoryParts; } // other methods ommitted for brevity </code></pre> } Finally the Stack Trace... <pre><code> 83985 [http-8080-6] ERROR

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
