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

 It's supposed to act this way, because "password" is in the "disallowed
 field names" list.
 
 You should only need to care about this if you've pregenerated the tables
 manually (and the forbidden list is in fact in error).

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?
