Re: Fulcrum SecuritySet error

I think (Peter can you comment) that one of our possible plans is to move the pull tool in with the review code. We were waiting on seeing if anyone wanted it.

On wombat - is was removed - as it was deemed not needed. The build system antelope is derived from one Anite use internally. Eric Pugh has been working refactoing and tidying it up for us - as part of that the new build arrangements have been applied to antelope. It now does not need a plugin. Eric - if this is wrong can you shout!).

On CVS - where did you see that? I can't find it anywhere to fix!

Thanks

Ben

Ah ok, that sounds neat - im just a little worried about using some other
pull-tool with no support for it. Thought the abstraction in itself is smart
enough.

I see the docs are updated now, but where did the wombat plugin go? Removed
that in the new version? (just saw a new version at the site too). Btw the
CVS doesn't work...

The path
/cvs:zebra/src/java/antelope 

Doesn't exist...

Heureka!

I finally got the zebra-antelope app to run... And seeing it uses the

situation where I'm building up the whole stuff and then finding out the


2.4


stuff in there isn't the future...





I think based on what Peter said it should be there. It is also worth saying that Antelope abstracts you from the change to the pipeline Peter is talking about as you only access that feature via the pull tool called Pengiun. This wlil be modified to handle whatever method they come up with in the final 2.4.

Also Anite the company that produced the original Antelope, Zebra etc - have got 3 large projects (over 20 developers) working on this framework and are not going to stop keeping it working with the latest Turbine at any point in the near future.

It was all written as we wanted a good template for our projects and an easy getting started sample for new staff. As we discovered that although Turbine (with all our extra bits) is easy to use - it is hard to find good documentation on how to get started.

On the subject of the docs - I think they have been fixed - little problem with forgetting to comit the latest version to Tigris!

Thanks

Ben



So should I use this?

Anyhow, it looks great otherwise and works well, you should check it out.
Just a bit of a warning, the help files for antelope are incomplete (3 ways
on 3 different pages, where you have to take the stuff that works)...

Hi,
I recently set up the Fulcrum security using the dynamic model using
hibernate for Antelope (a sample app for turbine found at
http://zebra.tigris.org ). I am not sure exactly what you are trying to achieve and I am sorry if I
have got the wrong end of the stick, but when you are adding the security
elements you should use the managers. These encapsulate all the hibernate
code for getting them into the database.

However if you are writing a manager you cannot use the securitySet.add()
method directly because it throws a "unimplemented exception" as you


stated.


You have to use the methods on the subclass. To get round this I did
something along these lines:

SecuritySet ss;
...
if (shouldAdd) {
if (ss instanceof GroupSet)
((GroupSet) ss).add((Group) e1);
if (ss instanceof RoleSet) ((RoleSet) ss).add((Role) e1); if (ss instanceof PermissionSet)
((PermissionSet) ss).add((Permission) e1);
}

If you have a look at Antelope though if will give you a lot more info on
how I set it all up.
Cheers
Mike

Subject: Fulcrum SecuritySet error

I'm using Fulcrum's security component to use Hibernate with Turbine 2.3.
Using the dynamic security model, I'm running into an issue. I'm


subclassing


the security objects from Fulcrum such as
org.apache.fulcrum.security.model.dynamic.entity.DynamicGroup. I have code
that looks like this:

    Set roles = a_Group.getRolesAsSet();
    Role role = (Role)m_RolesByName.get(k_RoleUser);
    roles.add(role);

I get this exception:

java.lang.RuntimeException: not implemented
        at
org.apache.fulcrum.security.util.SecuritySet.add(SecuritySet.java:257)
        at net.sf.hibernate.collection.Set.add(Set.java:156)
        at com.tagaudit.humpback.Humpback.attachRoles(Humpback.java:424)
        at com.tagaudit.humpback.Humpback.translateUser(Humpback.java:366)
        at com.tagaudit.humpback.Humpback.walkUsers(Humpback.java:316)
        at com.tagaudit.humpback.Humpback.run(Humpback.java:111)
        at com.tagaudit.humpback.Humpback.main(Humpback.java:87)

This appears to be caused be an odd combination of things:

1) The SecuritySet.add(Object) method throws an unimplemented exception,
apparently because it's subclasses have typed add() method that the author
wants to be called instead of the generic add(Object) method.

2) In the code, my roles object is a net.sf.hibernate.collection.Set


object.


This object is evidently a proxy wrapped around another Set, in this case


an


org.apache.fulcrum.security.util.RoleSet.

3) The RoleSet object has an add(Role) method and is a subclass of
SecuritySet.

4) Hibernate's Set.add method looks like this:

        public boolean add(Object value)
        {
                write();
                return set.add(value);
        }

5) Since the Hibernate add takes an object, when it calls set.add(), it


ends


up invoking the add(Object) call of the RoleSet object. Since this object
doesn't have one of those, it invokes the add(Object) method of its
superclass, which throws the unimplemented exception (see item 1 above).

Now, as near as I can tell, this means I'm pretty much hosed. I have to
alter either Fulcrum's set objects, Hibernate's set objects or both to fix
this problem.

Anyone have any advice for solving this?
