RichFaces problem on nuxeo tree]

headers Bogdan Tatar | 22 Dec 16:05

Hi again,

It seems that the problem is not at richfaces level as this is working 
just fine.The method that is called to populated the tree in nuxeo 
returns a list of DocumentTreeNode and on each node,which is a 
DocumentTreeNodeImpl, the method getChildren() is called in order to 
retrieve the children documents.This is done  by  making a call on 
DocumentManagerBean

public DocumentModelList getChildren(DocumentRef parent, String type,
            String perm, Filter filter, Sorter sorter) throws 
ClientException {

The problem appears on the statefull/stateless architecture,where  the 
modules that interact with a database of any kind are kept on a jboss 
instance and represents the statefull part of the architecture, and the 
web modules which represent,together with the corresponding api modules, 
the stateless architecture and are kept on another jboss instances.Both 
filters and sorters that are used in TreeManager service are registered 
by this service which is part of a stateless modules.The classes  of 
these filters and sorters are searched like this

TreeManagerImpl.class.getClassLoader().loadClass(
                        filterClass).newInstance();
so the classes of these sorters and filters have to be on a same module 
like the module where TreeManager service is,a stateless module.By doing 
this we get into problems when calling the method 'getChildren()' from a 
DocumentTreeNodeImpl.This method wants to use the method 'getChildren' 
from DocumentManagerBean,but the classes of the filters and sorters are 
not available on the statefull jboss instance where the 
DocumentManagerBean is located and an error like this is obtained

Caused by: java.lang.RuntimeException: java.lang.ClassNotFoundException: 
No ClassLoaders found for: 
org.nuxeo.ecm.webapp.tree.DefaultDocumentTreeSorter (no security 
manager: RMI class loader disabled)

The only solution I could find was to register both the filters and the 
sorters in an api module but I don't think this is such a good solution.
Any suggestions or help would be great.

Thanks a lot !
