Guenther Zwetti commented on AXIS-1931:
---------------------------------------

Btw: As you can see I've upgraded to axis 1.2RC3. (instead of 1.1) and
now I can not reproduce this error. Are there any major differences to 1.1
related to this problem?

> Calling a java webservice from a delphi rich client
>   public String processData(String xml) 
> I *** sometimes *** get the following error:
> The arguments do not match the signature.

> As this method only uses Strings as input and output parameters I do not suppose this to be a serialization/deserialization error.
> To handle different requests both, input and output string represent xml documents holding request and response parameters.
> Unfortunately the call succeeds in most cases. Only a few times this error occurs.
> Does anybody have any ideas why this happens or how it can be avoided?
