Hallo Zhang, unfortunately I can't reproduce the error on linux and I currently I have no possibility to test it in windows.

It appears to be an unknown exception (such that I catch with catch(...)). So what I can say for sure is that it is not a CORBA exception nor a CosNaming Exception nor an XmlBlasterException. I changed the code to individually catch also other exceptions such exception, string char* and int (the code is committed in cvs), hoping this way to get a better error message.

So I guess the better thing to do now is to use the debugger and step you to the CorbaDriver::connect method to better see what exactly happens.

Regards
Michele

Dear sir: I have downloaded the newest verion form your cvs and compile the xmlblaster with ORBACUS in windows 2000 system. when i compile the system, it report some winsock2 type redefine, so i change the #include <winsock2.h> in corbaconnection.h to #include <winsock.h>,and it ok to compile it . then i go on to run the demo helloworld2 in "xmlBlaster\demo\c++\bin" it report the following error, it remind me to send this error to maillist, i find the error is "connect" method, but i cannot find the reason.

I run the demo with -trace true and -call true , so this gives more information.

The first running method :
