> Key: AXIS-1931
> URL: http://issues.apache.org/jira/browse/AXIS-1931
> Project: Axis
> Type: Bug
> Environment: Win XP SP2, j2sdk1.4.1 or 1.4.2, axis 1.1, tomcat 4.1
> Reporter: Guenther Zwetti
> Fix For: beta-1
>
> 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.
> java.lang.IllegalArgumentException: object is not an instance of declaring class
> at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
> at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)
> at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)
> 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?
