OpenSessionInViewFilter: Error 500: Filter [hibernateFilter]

[igalmarino]

im using:

- Struts for the web context
- Spring for the bussiness contex
- Spring + Hiberante for the data access context

im using ContextLoaderPlugIn to connect struts with spring

<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation" value="/WEB-INF/presentationContext.xml, /WEB-INF/businessLogicContext.xml, /WEB-INF/dataAccessContext.xml" />
</plug-in>

my data access context is something like this:

<!-- ********** Data Sources ********** -->

<bean id="VEPDS" class="org.springframework.jndi.JndiObjectFactoryBean">

i configure the filter in web.xml

<filter>
<filter-name>hibernateFilter</filter-name>
<filter-class>org.springframework.orm.hibernate.support.OpenSess ionInViewFilter</filter-class>
</filter>
...
<filter-mapping>
<filter-name>hibernateFilter</filter-name>
<url-pattern>*.do</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>hibernateFilter</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>

but when i call a jsp file that list a collection that is lazy loaded i get this error:

Error 500: Filter [hibernateFilter]

the stacktrace is:

Your Filter fails because it can not extract the root WebApplicationContext since you did not configure one in your web.xml.

One thing you can do is to configure the root WebApplicationContext using ContextLoaderListener in your web.xml:

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/businessLogicContext.xml /WEB-INF/dataAccessContext.xml
</param-value>
</context-param>

and configure your struts ContextLoaderPlugIn using only the presentation context

<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation" value="/WEB-INF/presentationContext.xml" />
</plug-in>

from spring javadoc

Struts 1.1 PlugIn that loads a Spring application context for the Struts ActionServlet. This context will automatically refer to the root WebApplicationContext (loaded by ContextLoaderListener/Servlet) as parent.

Thanks ... i made this changes

web.xml

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/businessLogicContext.xml /WEB-INF/dataAccessContext.xml</param-value>
</context-param>
<filter>
<filter-name>hibernateFilter</filter-name>
<filter-class>org.springframework.orm.hibernate.support.OpenSess ionInViewFilter</filter-class>
<init-param>
<param-name>sessionFactoryBeanName</param-name>
<param-value>VEPSF</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>hibernateFilter</filter-name>
<url-pattern>*.do</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>hibernateFilter</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListe ner</listener-class>
</listener>

<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation" value="/WEB-INF/presentationContext.xml" />
</plug-in>

And everything works ok ...

i need to read more about the different context

thanks for the help

Can you show me the example code as how you actually add or update a record in the SimpleFormController?

I follow the instruction to configure web.xml, I use TransactionMananger

<filter>
<filter-name>hibernateFilter</filter-name>
<filter-class>org.springframework.orm.hibernate.support.OpenSess ionInViewFilter</filter-class>
</filter>
...
<filter-mapping>
<filter-name>hibernateFilter</filter-name>
<url-pattern>*.do</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>hibernateFilter</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>


Here is what I have in the FormController:

protected Object formBackingObject(HttpServletRequest request)
throws ServletException {
EditUser editUser = new EditUser();
String userId = request.getParameter("id");

if ((userId != null) && !userId.equals("")) {
editUser.setUser(mgr.getUser(userId));
...
}
else {
User user = new User();
...
editUser.setUser(user);
}
}
/*** I ASSUME WHEN USER IS CREATED, A COLLECTION OF MEMBER IS ALSO CREATED TOO

This is what EditUser looks like:

public class EditUser {
private List roles = null;
private List titles = null;
private List inRoles = null;
private String title;
private User user;

/*** with getters and setters...

}

Member class is many-to-one to User Class

My problem is:
-when update editUser, Only User info gets updated, Member table does not get updated

-when delete a user, it works the way it should, user and related records in Member table get deleted

-when add a new user, i get
[9/10/04 22:01:06:281 EDT] 11028e1 UserFormContr I com.espn.web.UserFormController Saving : jklcom : jklcom
