I have a Web Service (Axis) that takes in an object and will perform a function on that object. The object contains a String and a BufferedImage. The service will insert both things into a local database. Everything works fine when I set up my service to deal with an object that only contains primitive types (String, int, ...), but now that I changed it to take a BufferedImage, I get an error when I try to invoke the service:
Error: IllegalArgumentException: argument type mismatch
I check the deployed WSDL and everything looks good as far as I can see.
SOAP wouldn't know what to do with a BufferedImage - it can only transfer certain predefined object types (like int and string). Either you need to provide serializer/deserializer classes for it, or send the image encoded as a BLOB. This recent thread links to articles explaining how to transfer files, which may or may not be an option in your case.
