Just checking to see if anyone has any ideas to share? Basically, I would
like that an error message be shown if a user is not authorized to view a
particular collection. By default, an empty collection page is shown which
gives the impression of an "empty collection"
I am using DSpace version 4.1, jspui version.
Please let me know if you need any additional information.
Regards,
Shazia

Subject: Display error msg on Collections page when user is not authorized
to view Items
To: DSpace Tech <dspace-tech@lists.sourceforge.net>
Hello All,
I am working on a request for change in my DSpace installation. The
requirement is that an error message like "Access Denied" be displayed on
the Collections page when a logged-in user tries to access a Collection
that he/she is not authorized to access.
The default behavior is that no Items are displayed and is there a way to
change this and add an error msg?
Here is what I tried:
In *HandleServlet.java*, I modified the code and added:
collectionHome()
{
...
if (AuthorizeManager.authorizeActionBoolean(context, community,
Constants.DEFAULT_ITEM_READ))
{
// set a variable to indicate read access and hence display
the community heorarchy
request.setAttribute("read.access", Boolean.TRUE);
}
else
{
request.setAttribute("read.access",
Boolean.FALSE);
}
..
}
*collection-home.jsp*
...
Boolean readAccess =(Boolean)request.getAttribute("read.access");
boolean read_access = (readAccess== null ? false :
readAccess.booleanValue());
...
<% if(!read_access) { %>
<p style="color:red; font-size:16"> Access Denied </p>
<% }
In he UI, I have a Collection C1 with the following policies:
C1:
DEFAULT_ITEM_READ : Group (COLLECTION_25_DEFAULT_ITEM_READ)
DEFAULT_BITSTREAM_READ: Group (COLLECTION_25_DEFAULT_ITEM_READ)
The only member in group COLLECTION_25_DEFAULT_ITEM_READ is user A.
When I log in as user A, I get the "Access Denied" error message on all
Collections including C1. I'm not sure what I'm missing here? I'm not sure
if I am looking at the right permissions.
Does anyone know of an alternate approach- from the CollectionItemList.java
perhaps?
Regards,
Shazia
