Welcome! I think your problem could be as simple as the "/" at the start of your class name:
<servlet path="/myFormHandler" class="/ xxx.xxx.xxx.myprojects.provaupload.server.MyFormHandler"/> Try changing it to this: <servlet path="/myFormHandler" class="xxx.xxx.xxx.myprojects.provaupload.server.MyFormHandler"/> Now, if that isn't the problem (maybe the "/" was a typo in your post, but not in your gwt.xml), then I would ask you to make sure that you are compiling your servlet (javac from the command line, or an IDE such as Eclipse will do this automatically). The compiled servlet class needs to be on your classpath when you run hosted mode. Hope that helps. - Isaac On Tue, Apr 7, 2009 at 1:41 PM, Nickelnext <[email protected]> wrote: > > Hello everyone, > > this is my first post and i pray i did not do anything wrong by write > it here. > I've been looking for the solution of my problem for days over the > web, but i did not find what i need so, i'm posting right here at > google groups hoping someone more skilled than me and very patient > could help me. > > Before start, i let u know how my workspace is configured: > package: com.my.site.myprojects.provaupload > public >>css, html, > ProvaUpload.gwt.xml > package: com.my.site.myprojects.provaupload.client >>>ProvaUpload.java > package: com.my.site.myprojects.provaupload.server >>>MyFormHandler.java > > Now, here's my problem: > > I need an upload form to upload a small file on the server, i have my > simple ProvaUpload.java like this > > public void onModuleLoad() { > final FormPanel form = new FormPanel(); > form.setAction(GWT.getModuleBaseURL() + "/myFormHandler"); > > // Because we're going to add a FileUpload widget, we'll need > to set the > // form to use the POST method, and multipart MIME encoding. > form.setEncoding(FormPanel.ENCODING_MULTIPART); > form.setMethod(FormPanel.METHOD_POST); > > VerticalPanel panel = new VerticalPanel(); > form.setWidget(panel); > > // Create a FileUpload widget. > FileUpload upload = new FileUpload(); > upload.setName("uploadFormElement"); > > panel.add(upload); > Button button2 = new Button("Submit", new ClickListener() { > public void onClick(Widget sender) { > form.submit(); > } > }); > // Add a 'submit' button. > panel.add(button2); > > // Add an event handler to the form. > form.addFormHandler(new FormHandler() { > > public void onSubmitComplete(FormSubmitCompleteEvent > event) { > // When the form submission is successfully completed, > this > // event is > // fired.
