multi-level (3-level) dependant objects?

[Nevin Ng]

Dear all,

Does orion support mutli-level dependant objects in its OR mapping?

for example, I have the following rational relationship in my database:

Order <-- 1:m --> OrderLine <-- 1:n --> OrderLineDetail

I know orion is capable to have 1:m (2 levels) dependant mapping according to 
http://www.orionsupport.com/articles/complex-or.html. But I cannot find anywhere 
mention how to setup 3 levels dependancy.

Could anyone point me to any reference? BTW, does entity <--> entity dependant suport 
one-to-many relationship?

Regards,
Nevin

Bug in deployment descriptor?!

[Nevin Ng]

Hi,

I wonder if you have met this situation before, I trying to deploy an entity bean with 
one of the field named "password".   I have write the corresponding orion-ejb-jar.xml 
for the persistence mapping within database. Everything seems fine, the xml in the 
application-deployment directory is correct. Until the whole deployment is done, which 
orion compiled all the generated files, the seems to be correct orion-ejb-jar.xml has 
been updated with the "password" field mapping becomes "password_".  Is this a bug or 
just my problem?!

I have tried all the ways and nothing can stop orion change the from "password" to 
"password_"!   When I change the mapping to something else such as "blahblahblah" its 
ok, but not "password".

I really confused about this strange behavior

Question on EJB Finder

[Nevin Ng]

Hi there,

I'm now working on the ejb finder methods with orion, I have some basic experience 
with it already and know how to do some basic declaration such as sub-select finder, 
etc. 

I know that orion will map arg1 to $1, arg2 to $2 and so on, but how about if I want 
to pass an array to the finder?

e.g. I have a entity bean that will hold books, each of them will have an owner_id 
field. Now I want to define a finder call:

public Collection findByOwner(Integer[] ownerID) throws RemoteException, 
FinderException;

Then how could I define such argument in orion-ejb-jar.xml?!

Cannot dispatch url with session id?

[Nevin Ng]

Hi there,

I found that when requesting a RequestDispatcher's path is url encoded with session 
id, the returned object will be null.

e.g.

RequestDispatcher rd = request.getRequestDispatcher(response.encodeURL("/index.jsp"));

this rd will return null if the encodeURL produces 
"/index.jsp;jsessionid=OOLKMGKDDCMA"   

Is this a bug cause I have no problem with other application server?
