couldn't find any good examples online. can anyone give me a good sample?
i use SOAP::Lite to invoke the call and get the result back. it's an object
written by Java. how can i define
the class in Perl? i tried wsdl2perl. did not get any luck.

We are using Visual Basic to control 2 external RS-232 peripherals. The data
size is 200 bytes per transmission. It comes in and out random with speed
of 19.2Kbps. We find that the Visual Basic software is briefly interrupted
and the data somehow is not processed or lost when the PC is doing some
other tasks such as burning a CD, entering to Screen Saver etc. We'd like
to know if there is a way to control the VB SW Priority Level as it can be
done using C++.

SOAP不是xml么？

The data loss is due to overrun. Try to set flow control options when
setting up serial connection. (e.g., using RTS/CTS). Raising thread priority
does not always work.

right. The webservices call returns something like
myobject:hash(ea214653)
How to interpret this obj. By wsdl? Or is there any function I
Can use to parse the obj. Info? Thanks.

the server side provides wsdl and the retunred object class is written by
Java. but i dont know how to parse the returned info. should i use SOAP::
WSDL module?
