Hi all,
I installed a ZSI 2.0_rc2 on machine geron045.ncl.ac.uk.I run the
HelloWorld.py service on the this machine i.e.
http://geron045.ncl.ac.uk:8088/HelloWorld.py.This service has one operation
called "HelloWorld" which accepts one argument and return this argument.
Then from the another machine i.e "geron007.ncl.ac.uk" I tried to access this
HelloWorld service which is deployed at
http://geron045.ncl.ac.uk:8088/HelloWorld.py through AXIS2 client.I got the
processed failure message.I monitor the soap messages going back and forth
through TCPMON.The output for this is given below:
Request:

Just to clarify things further.I did one more thing,I removed the argument for
the HelloWorld operation so now it is accepting no argument.And now when I
tried to access the same service.I got the error again.By monitoring the soap
messages going back and forth through TCPMON.This type the error changes to
something else as given below:
Request:
POST /HelloWorld.py HTTP/1.1

I am quite surprised by these errors.I am attaching with this mail my
HelloWorld.py service and AXIS2 client code.I would appreciate if some guy
would explain me the strange behavior of this simple scenario.
Kind Regards
