Hello,
I am trying to write a serializer for the Person class (with two attributes name and age and their getter and setter) and we have an exception when we try to display the WSDL :
AXIS error
Sorry, something seems to have gone wrong... here are the details:
Exception - java.lang.reflect.InvocationTargetException
Person
Hi there, this is an AXIS service!
Perhaps there will be a form for invoking the service here.
There is no clear documentation about writing a custom serializer, please help me to solve this problem.
Best Regards,
Nawal
This the source code of serializer/Deserializer and the WSDD:
