Grouper Users - Open Discussion List

[Chris Hyzer <>]

Is there more of a stack in the logs, maybe the grouper error log?  All 
information would be helpful.  Maybe you have some jars that conflict... 
generally the grouper client is easier to integrate into other projects like 
uportal since it is one jar with no dependencies, but maybe it is too late 
for that :)

Thanks,
Chris

Subject: [grouper-users] Grouper 1.6.3 - Problem on some request

Hi,

We have some problems in getting membership, here is the error that we get in 
our logs :

java.lang.ClassCastException: Problem in HibernateSession: 
HibernateSession: isNew: true, isReadonly: true, grouperTransactionType: 
READONLY_NEW,
Exception in list: (class edu.internet2.middleware.grouper.Group),
ByHqlStatic, query: 'select g from Group as g  where g.uuid in (:Q2C71BB40, 
:Q2C71BB41, :Q2C71BB42)', cacheable: false, cacheRegion:

Do you know where this could could ?

To explain our context we integrated our own group manager in uPortal (using 
only grouper api) and this error occure when a portlet do a
getUserRole() (JSR168) to get groups of a user, and the portlet do several 
request for a user. This is not a big problem as the error is well 
intercepted, but sometimes the user don't get all ressources that he must 
get. Is it possible that too much request overload the grouper api in doing 
request on database ? I already have a such problem
(classCastException) with hibernate due to a such case.

Thanks

Julien
