Hi,

I don't have at test case yet. But I did some further testing, tried JacORB 3.4 and figured out that binary transmission works with version 3.4. So it makes me believe that something that changed between version 3.4 and 3.5 causes the issue.

I will do further research and will let you know.

Regards, Gotthard

Hello Nick,

after upgrading JacORB from version 3.3 to version 3.5, the binary transmission fails with the following exceptions:

org.omg.CORBA.MARSHAL: Server-side Exception: null  vmcid: 0x41540000  minor code: 22  completed: No
                at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)
                at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62)
                at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45)
                at java.lang.reflect.Constructor.newInstance(Constructor.java:408)
                at org.jacorb.orb.SystemExceptionHelper.read(SystemExceptionHelper.java:222)
                at org.jacorb.orb.ReplyReceiver.getReply(ReplyReceiver.java:458)
                at org.jacorb.orb.Delegate._invoke_internal(Delegate.java:1475)
                at org.jacorb.orb.Delegate.invoke_internal(Delegate.java:1244)
                at org.jacorb.orb.Delegate.invoke(Delegate.java:1232)
                at org.omg.CORBA.portable.ObjectImpl._invoke(ObjectImpl.java:475)
                at ico.corba.fs.idl._FilesystemStub.uploadChunk(_FilesystemStub.java:954)

After analyzing the CDROutputStream.write_octet_array method, it seems that the bytes get cached in the deferredArrayQueue, for later transmission. But when it is time to send the bytes to the server, the bytes in the deferredArrayQueue seem not to be correctly added to the outputstream.

However if I set the jacorb property "jacorb.deferredArrayQueue" to "0" the bytes are transferred correctly to the server and the binary transmissions works without problems.

Have you got any clue, where a problem could occur?

Hmmm. The only recent changes in write_octet_array were in
http://jacorb.org/bugzilla/show_bug.cgi?id=941 which changed 3.3beta.

Are you able to provide a test case?

Thanks

Nick
