I think I am going for the first method that you
suggested - create a user bean and store it in a session object at login. My concern is that I use
container managed authentication at login. After the
container does its job, is there any way other than
using an Action that delegates the business tier to
search the database and obtain the value of
field_of_specialization? If an action has to be
involved at this point to form a session object, does
it suffer the the disadvantage of being overwritten if
the user has more than one browser window opened?
If you include a method call in all your actions to check whether the user is logged in, and then whether the session bean exists already, you can determine whether to create the bean or not each time. This won't be affected by the number of browser windows open, since you will only create the user bean once.
at the problem - I provide a buttion in editor's page, which is a JSP tile:
<req:isUserInRole role="editor"> <html:form action="/do/editor/Category"> <html:submit>View Articles</html:submit> </html:form> </req:isUserInRole>
If the button is clicked, I attempt to use an Action (via the path /editor/Category) to search the database for the field_of_specialization. However, I got this message in the browser:
[ServletException in:/article/content/menu.jsp] Cannot retrieve mapping for action /do/editor/Category'
and in my struts-config.xml
<action path="/editor/Category"
type="org.apache.artimus.article.EditorViewAction">
<forward
name="success"
path="/menu/Find"/>
</action>
Sorry but I can't see why that problem should occur from the info you give. Maybe if you start a new thread with a relevant subject title for this then somebody may be able to help. If you could specify exactly when or which page causes the error, it might help too.
