IIOP BUG

[dummyjim]

Well I think so... :-(

I use "com.sun.jndi.cosnaming.CNCtxFactory"
to access to EJBs thru RMI/IIOP.

All OK untill I have 2 overwritten methods.

i.e.

getData(String name)
getData(int age)

Sometimes (often) it returns "CORBA.BAD_OPERATION"

As far as I understand there is a list with methods somethere and if parameter doesn't match it returns a error insted of looking for another one...

The code works perfectly with RI.

Thank you very much,

[adrian.brock]

This works for me,
I just added a specific test for this to the
jboss testsuite.
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/jboss/jbosstest/src/main/org/jboss/test/helloiiop/ejb/HelloBean.java?annotate=1.1.2.1

Perhaps you can post an example that doesn't work
as a bug at
www.sf.net/projects/jboss

Adrian

Well, you are rigth.

I have no idea what is wrong with my program :-(((

Thank you.

Hi there,

I have no idea what's happen with forum. Some posts just has been removed... :-(

Well, The question is:

Am I Dummy? ;-)

if I have two overridden business methods thich starts with "get" prefix a program doesn't work. I get an exception:

I understand that it could work on SUN RI by error :-),

but why it works also if I change methods name to gedMyList (for example)?

Hello Adrian!

I have seen iiophellotest and I didn't understand which context factory it uses. I mean is it "com.sun.jndi.cosnaming.CNCtxFactory"?

If you can change the test files can you rename

public String hello(String name)
throws RemoteException;

public String hello(int number)
throws RemoteException;

to "getHello"??? to try it on.

Sincerely Yours,

D.

It's me again...
