Create a servlet and call it from client side on clicking a button. 

String servletName = GWT.getModuleBaseURL().replace("/" + GWT.getModuleName(), "")
                     + "pdf_download_servlet";
Window.open(servletName, "", "");

For a servlet code please have a look at need a servlet to download a file.
