newbie - visibroker and using IR

[Raymond]

Hello,

I am using Visibroker 4.5 for Java. I am trying out a sample program from
"Java Programming with CORBA" 3rd edition by Gerald Brose et. al. (chapter
9, DII example)

I am trying to access the interface repository but my call to:
FullInterfaceDescription full_if_desc = if_def.describe_interface();
gives me the following run-time error:
org.omg.CORBA.BAD_PARAM: minor code: 0 completed: No
at java.lang.Class.newInstance0(Native Method)
at java.lang.Class.newInstance(Class.java:237)
at com.inprise.vbroker.orb.SE.read(SE.java:28)
at
com.inprise.vbroker.orb.DelegateImpl.handleReply(DelegateImpl.java:711)
at
com.inprise.vbroker.orb.DelegateImpl.invoke(DelegateImpl.java:606)
at org.omg.CORBA.portable.ObjectImpl._invoke(ObjectImpl.java:294)
at
org.omg.CORBA._InterfaceDefStub.describe_interface(_InterfaceDefStub.java:18
1)
at DiiClient.main(DiiClient.java:89)

I can't for the life of me figure out why -- anyone have any ideas?
I have the osagent started, I have the IR started (using irep MyIRName
HelloWorld.idl)
and I've verified that I am able to obain the InterfaceDef by calling
InterfaceDefHelper.narrow(...)

Any help would be greatly, greatly(!) appreciated. Thanks!

Hello Raymond,

Could you see if you have given the wrong operation name in your DII
invocation. I would say, its not the ORB which is making the mistake, it
must be the code. Well where could have been the mistake.

+ In the IDL file - the operation name was written wrongly.
+ In the Server side, you might be doing something wrong about how you
created an operation.
+ In the Client side, you will need to give the name of the operation
same as that which is given in the server side.

So long,

Jacob.
