Axis Client is not thread safe.

[Andrew Perry2 <PE...@uk.ibm.com>]

Hi,

I have built and attempted to run the WinClient Calculator service
threading tests supplied by Lahiru Wimalasiri. The test fails. It seems
that 1 instance of the stub is overwriting the other instance and this
causes an exception. If I amend the test code to only instantiate 1
instance of the Calculator stub then it works, regardless of whether the
Calculator stub is in the main program or a thread. Running the supplied
test with 2 stubs instantiated, 1 in each thread, then the tests fail and 1
of the threads just crashes. It is not consistent which thread crashes. I
have also tried this with 1 instance of the Calculator stub in the main
program and 1 in a thread and it fails the same way.

I have written a Java version of Calculator web service running on
WebSphere and this works OK.

This seems to show that the Alpha 1.2 version of axisclient.dll is not
thread safe.
