Attaching file in Axis SOAP question

I have a wsdl file and was able to generate java codes using WSDL2Java of Apache Axis. I use the generated client code to connect to a SOAP server and everything is fine until i attached a file to the SOAP message. I pasted some part of my code below. The only code that i added to attach a file is on line number 2. Without it everything is running fine. What am i doing wrong here? Is there something i need to do to be able to attach the file that i need to send? Thanks in advance.

1. myStub = new MyBindingStub(new URL(SOAPURL), new Service());
2. myStub.addAttachment(new DataHandler(new FileDataSource(new File(IMAGE))));
3. soapResp = myStub.submitData(...);

This is the error:
