  hmmm interensting. of course i assume that is 
  just a typo where you have the semicolon and comma after the proable remote 
  object.narrow as it would not compile that way. 
  
  I remember getting these wrapper classes 
  returned, but I am sure when I was doing it I was not casting correctly. I 
  assume you are getting an exception on execution?

Hi,

I 
am casting the narrowed object properly my code is 

CategoryHome catHome = 
(CategoryManagerHome)PortableRemoteObject.narrow( 
ctx.lookup("java:comp/env/CategoryManager");, 
CategoryManagerHome.class);

but this throws up a wrong ( maybe intermediate 
class) .(CategoryManagerHome_StatelessSessionHomeWrapper3).

I am using Resin as 
the servlet/ web server now and it works fine ( as resin acts like any other 
java client would do).
I would rather use 
orion for the full setup if i can get over with this 
problem.

Thanks
Krishnan

  you still have to cast it to a thisHome

Subject: getting EJB home from 
JSP

Hi,
I am deploying ejbs, and jsps using a source-directory 
method with development set to "true"( instead of packages classes into 
ears or wars). When i try to get a handle from JNDI for EJB home class 
within my jsp i am getting following error:
java.lang.ClassCastExceptionat 
com.sun.corba.se.internal.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:296)at 
javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:137)
This isbecause Orionis returning some 
wrapper class instead of 
thehome.(CategoryManagerHome_StatelessSessionHomeWrapper3).
The same code works fine if i call from a standalone 
java test client, in which case Orion returns some _proxy3 
class which gets casted to the proper class.
Would appreciate any help and insights on this 
problem.
Thanks Much,
Krishnan

Hi Krishnan,

Is that REALLY your code?  If so, the problem is probably that you declare the
variable on the left to be a CategoryHome, but the right hand side is a
CategoryManagerHome.

The fact that Orion returns a CategoryManagerHome_StatelessSessionHomeWrapper3
rather than a CategoryManagerHome is expected; after all, the home is an
interface, not a class, and so cannot be instantiated.

Hi Nick,

sorry i just (mis)typed out the equivalent of my code. Have
CategoryManagerHome on both sides of the expression ( the code compiles and
works fine for a test java client).

I can understand that Orion has some intermediate classes but it should
resolve to proper class when you look up the Home interface from the JNDI
which is not happening.

Another intresting thing is the intermediate class returned is __proxy3 for
a java client but sessionwrapper3 for a jsp client?

Thanks
Krishnan
