Security and Roles related
Does STRUTS provide integration with any security framework independent of
the underlying application server. Basically I am looking at services like
isUserInRole(), getRole() and the sort.

RE: Indexed property names - the real story
Posted by Richard Mixon <rn...@custco.biz>.
Linda,
Thanks - that cleared things up. Things are working great now that I let the
indexed methods use a different name. Many of the examples and howtos on
indexed properties are not at all clear on this.
The list methods turn out to only be needed by my action class, so the fact
that their names do not correspond to the the property= name on my JSP does
not really matter.

The problem is that you end up having two identically named methods that
return different types. How is the compiler supposed to know which one to
use? I had this same problem myself for a while, because you are right that
is what seems to follow JavaBean specs. But your solution is exactly what
you should do, you are still following spec because you do have a getter
method with the correct name. You just also have an additional getter
method to return one within the List. I think this answers your question.

The problem is naming of the getter for my list of line items. At first I

With the indexed getter/setters as above, it does not work. However, if I

Indexed property names - the real story
Posted by Richard Mixon <rn...@custco.biz>.
First, sorry for the long posting - it shorter than a few, but not many :).
I've read a number of very good postings on the list on how to handle
indexed properties using the "<logic:iterate" tag. In spite of this I'm
having a bit of a problem determining what the corresponding getter/setter
names should be.
The problem is naming of the getter for my list of line items. At first I
had the following signatures
// First to get and set the entire list
public List getCurrLineItems() ...
public void setCurrLineItems(List lineItems) ...
// Next to get and set individual indexed items in the list
public LineItem getCurrLineItems(int liDex) ...
public void setCurrLineItems(int liDex, LineItem lineItem) ...
With the indexed getter/setters as above, it does not work. However, if I
name them differently from the List getter/setters they work (for example
names then getCurrentLineItems and setCurrentLineItems instead of
getCurrLineItems and setCurrLineItems). This appears to be contrary to all
of the examples I can find and the JavaBeans spec. Before proceeding I want
to clear this up.
With the matching names for indexed properties I could not get my JSP page
to see the line items. I tried the "logic:iterate", "nested:iterate" and
"logic-el:iterate" variations of the Struts iterate tag. I also tried using
a JSTL "<c:forEach " loop.
In my action, I set the form bean in the request, could print the form bean
and see all of the line items, . But when it got to the JSP page, BeanUtils
said there currLineItems property was empty.
After deciding that there might be a problem with my property names
(grasping at straws), I discovered that using different names for the
indexed methods seems to have fixed things.
Any ideas on why this is happening. Better yet, how should things work?
I've cut down a piece of my JSP page and my form bean below, trying to keep
enough info without making it too long to read.

You can use Struts with SecurityFilter, which is a filter-based system
designed initially to work just like container-managed security, with a few
extensions.

Re: Security and Roles related
Posted by Dan Tran <da...@hotmail.com>.
You can assign a role attribute with multiple role names in the action
configuration.
Underneath, struts uses isUserInRole to check against the list you provided.
However, checking security is better off to let container do it for you.

struts provide support for JAAS and JAAS further supports the security roles
and accesses independent of mechanisms.
will that do?
