Re: [openorb-users] NameService (INS) exception...

[A.J. B. \(ajblanch\) <ajb...@ci...>]

MANY Thanks for the reply!

Yes, a CLASSPATH issue crossed my mind. I looked at the code in the =
method at the top of the exception. I am not sure what jar file(s) I =
might be missing. Also, this server has been running for days and then =
slides into this condition. Once re-started, its good again for several =
days. I will try to find a means to reproduce this in short order, =
otherwise the DEBUG log file will need to be managed so it does not grow =
too large (it is not today).

INS Code snipit:
-----------
 1169     private void handle_system_exception( =
org.omg.CORBA.SystemException ex )
 1170     {
 1171         m_sending_system_exception_any =3D null;
 1172         m_sending_system_exception =3D ex;
 1173         m_sending_system_exception_id =3D =
SystemExceptionHelper.id( ex );
 1174         m_reply_status =3D =
org.omg.PortableInterceptor.SYSTEM_EXCEPTION.value;
 1175     }

CLASSPATH:
---------
CLASSPATH=3D$CLASSPATH:/opt/BTSoorb/lib/logkit.jar:/opt/BTSoorb/lib/openo=
rb-1.3.1.
jar:/opt/BTSoorb/lib/openorb_tools-1.3.1.jar:/opt/BTSoorb/lib/xerces.jar:=

Upgrading the NamingService to 1.4.0 would probably not solve your =
problem, at least the WHATSNEW file for the OpenORB NamingService module =
doesn't mention anything related.

Hard to tell, but NoClassDefFoundError looks more like a classpath setup =
problem than a bug in the OpenORB code. Can you run the code inside a =
debugger and find out which class is missing? Or maybe the class is =
there, but it's static initializer throws an Exception that is converted =
to a NCDFError?

Lars
