Axis asking me serializers for everything

[Miguel Griffa]

Hi all,
I have a ws that I deploy on axis, some classes that go from one way yo 
the other.
I'm getting a bunch of errors like this:

- The class java.awt.Color is defined in a java or javax package and 
cannot be converted into an xml schema type.  An xml schema anyType will 
be used to define this class in the wsdl file.
- The class java.awt.Font is defined in a java or javax package and 
cannot be converted into an xml schema type.  An xml schema anyType will 
be used to define this class in the wsdl file.
- The class java.util.Set is defined in a java or javax package and 
cannot be converted into an xml schema type.  An xml schema anyType will 
be used to define this class in the wsdl file.

is there any way to tell axis that the default serializer is bean 
serializer?
or another way to fix this?
Thanks in advance!
