Guest Download Servlet

jjf — Thu, 03 Jan 2008 18:27:41 GMT

I have a space which I want anonymous users to have read access to, so I've added the guest account to the space as a Consumer. This works fine with CIFS and the mapUnknownUserToGuest file system param. When I try accessing files in the space via web link:http://localhost:8080/alfresco/download/d

I'm not sure what's wrong here - it sounds like it should work, the error is strange. If you are getting AccessDeniedException it's like the Guest user does not have permissions on their own Person node or the Guest home space. You said it's pretty much an out-of-the-box deployment but are there any changes relevant to the Guest home space or Guest person node?

Thanks for the response.

The guest user is a Consumer on the Guest Home space (as well as Company Home).

I did have to recreate the guest user because it looked like it was corrupt (the username became something like "guest123213-213123-213") and people couldn't login through CIFs using the guest account. Once I recreated it, people were able to get in through CIFs. Could it be that recreating it fixed CIFs but broke the web client?

Check that the Guest user Home Space is set to the Guest space, and ensure that the Guest user has Write permissions on the Guest Person node.

I've verified the Home Space for Guest is "Guest Home". How do I ensure the Guest user can write to the Guest person node?

Log in admin - go to the Node Browser tool in the Admin Console. Navigate into workspace://SpacesStore store, then into:
{http://www.alfresco.org/model/system/1.0}system then into {http://www.alfresco.org/model/system/1.0}people. The second item in the Children list will probably be the Guest user, click it. Under Permissions you should see: Read guest ALLOWED
If not, then you'll need to write a small Javascript (or whatever API you prefer) to modify the permission on that node so that guest has Read.

Thanks. That might be the issue. "guest Allowed" is not set as a permission. I'll let you know how it turns out.

I tried running JavaScript to update the permission but received the following error when running:

Please correct the errors below then click Finish.
Failed to run Actions due to error: Failed to execute script 'workspace://SpacesStore/6c51b4e6-0a1f-11dc-a36b-194fa988ca23': org.mozilla.javascript.Context.initStandardObjects()Lorg/mozilla/javascript/ScriptableObject;

This happens on any JavaScript I run, even the samples. Any ideas?

I can always use the Java API to fix the permission issue but I'd like to figure out what's wrong with the JavaScript.

Is there any more to that error trace? It looks like a bigger problem with your setup - what app-server are you using?

I am running on Weblogic 9.2.

is the information i needed

Weblogic has a built-in version of Rhino JAR which is conflicting with the one we supply with Alfresco.

See the instructions here: http://wiki.alfresco.com/wiki/Install_BEA_Weblogic steps 6/7.

Ah ha. That makes sense. Thanks for the info/help, Kevin.

Re: Guest Download Servlet

jjf — Mon, 24 Mar 2008 13:20:22 GMT

I was able to fix the issue. After granting authority to the Guest user, the download servlet now works! Thanks for the help.

On a somewhat related note, when a user tries to access a file as Guest, and Guest does not have permission to view, it sends the user to Guest Home in the web client. Is there a way to display an error message "Access denied." instead of forwarding to Guest Home? I am going to start looking in the source to see if I need to write an aspect or something. Is there a better way to do this?
