The example from FormPanel's javadoc says:
"...Assuming the service returned a response of type text/html, we can get the result text here (see the FormPanel documentation for further explanation)..."
However the javadoc doesn't explain a bit about this topic. Has anyone found how to get the HTML response sent back from server after a form submission?
Add a FormHandler to your FormPanel, and in onSubmitComplete you will receive a FormSubmitCompleteEvent. Invoke its getResults() method to obtain the result.
form.addFormHandler(new FormHandler() {
public void onSubmit(FormSubmitEvent event) { // validation etc }
public void onSubmitComplete(FormSubmitCompleteEvent event} {
Window.alert(event.getResults()); // display the result
}
};
//=========== in the client side:
SubmitCompleteHandler sch = new SubmitCompleteHandler() { public void onSubmitComplete(SubmitCompleteEvent event) { //get back the data results that had input the .xml String dpsString = event.getResults();
//And do your wanted action with the result
System.out.println(dpsString);
}};
uploadForm.addSubmitCompleteHandler(sch);
//=========== in the server side:
// parse and handle file, e.g. if there is an xml file
...
InputStream fileImputStream = uploadItem.getInputStream();
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
Document doc = docBuilder.parse(fileImputStream);
doc.getDocumentElement().normalize();
System.out.println("Root element of the doc is " + doc.getDocumentElement().getNodeName());
...
//Response to the request with the result
dpsString = doc.getDocumentElement().getNodeName();
response.getWriter().write(new String(dpsString));
Following the answear from "Robert Munteanu" you should look at:
And there you can see :
getResults
public java.lang.String getResults()
Gets the result text of the form submission.
Returns:
the result html, or null if there was an error reading it
Tip:
The result html can be null as a result of submitting a form to a different domain.
