Web Service that needs a User Input from a JSP

Hi guys! I have successfully created a webservice using JAX-WS. However, I have a problem. My webservice needs some user input (e.g. a vtoken) from a jsp page to complete the processing and be able to send a reply back to the web service client. This input could not be provided by the webservice client at all, which is why im having this problem . I'm not sure how I could be able to implement this and I need some help. Any suggestion would be greatly appreciated. Thank you very much!
