updated authldap to get the groups to work (king of)
Method getGourps was revised. Attributes variables were set there. Other wise, when it caught a referral exception and started a thread, this will caused a exception problem. When string array groups were returned by method getGroups in getPrincipals method, we should check if the groups is null or not. Otherwise it will cause a exception problem. This revise is for bug 445.
In hasPermission method, a situation was considered: if no user and group, the permssion will be true. This is for the command line invocation.
Method endElement in AccessControList was revised. A feature that put access document itset into xml_access was added.
In hasPermission method, a rule for access document is implements. If user want to write a access document, it should hhave "all" permission.The permission for access document now is looking up in xml_access table directly, rather get same permission to data set document.
In order to increase data file docid, method registerDocument was revised. Now it not only insert a new data file record to xml_documents table, but also can update the data file documents. Moreover, it can archieve the old version to xml_revisions table. Two other private methods were added to handl these futures: deleteXMLDocuments and getLatestRevisionNumber.
fixed my tagging error
some small changes I had to make to get the QAENGINE demo to work right. this should be committing in a branch
We decided that the permission for a user to an access documents is as same as to the data set document(which contains the access document). In order to do this, we need to look-up xml-relation table. If we could find the data set document id, just check the id. If we couldn't find one, we need check if the user is owner. If it is, has permission. Otherwise, doesn't have.
Add a new method getDataSetId to the class. The permission policy for access documents is: the user will have the same permission as data set file. (There is no entry in xml_access table for access document.
