[openorb-general] NoClassDefFoundError from NameServer

[Bill L. <bli...@to...>]

I have recently migrated from OpenORB 1.2.0 to 1.3.0 (on Win2K) and I am
generating a NoClassDefFoundError from the NameServer. I recompiled a
debug version of OpenORB and here is the stack trace that appears:

java.lang.NoClassDefFoundError
        at
org.openorb.net.AbstractServerRequest.handle_system_exception(Abstrac
tServerRequest.java:1138)
        at

org.openorb.iiop.IIOPServerChannel.close(IIOPServerChannel.java:426)
        at
org.openorb.iiop.SocketQueue.process_or_enqueue(SocketQueue.java:272)

        at org.openorb.iiop.SocketQueue.receive(SocketQueue.java:201)
        at
org.openorb.iiop.IIOPServerChannel.run_recv(IIOPServerChannel.java:56

        at
org.openorb.net.ServerManagerImpl$ChannelRecvRunner.run(ServerManager
Impl.java:909)
        at java.lang.Thread.run(Unknown Source)

This stack trace does not appear on start up, but rather it is later on.
It does not appear on every request and I do not have a good handle yet
on when the stack trace appears. Sometimes, I do get multiple
NoClassDefFoundError exceptions, so it is not crashing the NameServer.
From the code, it looks like it is choking on this line:
        m_sending_system_exception_id =3D SystemExceptionHelper.id( ex =
);
However, SystemExceptionHelper is in the OpenORB JAR.

Here is my batch file to start the name server:

<start batch file>
@echo off

set nsClass=3DC:\Tomo\ds\OpenORB\openorb_ins-1.3.0.jar;
set ooClass=3DC:\Tomo\ds\OpenORB\openorb-1.3.0.jar;
set psClass=3DC:\Tomo\ds\OpenORB\openorb_pss-1.3.0.jar;
set tsClass=3DC:\Tomo\ds\OpenORB\openorb_ots-1.3.0.jar;
set
xtClasses=3DC:\Tomo\ds\OpenORB\avalon-framework.jar;C:\Tomo\ds\OpenORB\lo=
g
kit.jar;

set classpath=3D%nsClass%%psClass%%ooClass%%xtClasses%%tsClass%

echo Starting NameServer on port %1

java org.openorb.ins.Server -ORBPort=3D%1
<end batch file>

Any ideas on this problem?
