GWT RPC file upload problem

[arun.raai]

Hi All,

I am getting multipart null even it is set (ENCODING_MULTIPART) on client side.

I am working with gwt 1.5.3
-------------
My Code
-------------


1. GWT widget: FormHandle

RootPanel rootPanel = RootPanel.get();

final FormPanel form = new FormPanel();
rootPanel.add(form);
form.setAction(GWT.getModuleBaseURL()+"MyFormHandler");
form.setEncoding(FormPanel.ENCODING_MULTIPART);
form.setMethod(FormPanel.METHOD_POST);
.........
.........
.........

panel.add(new Button("Submit", new ClickListener() {
public void onClick(Widget sender) {
form.submit();
}
}));

.........
.........
.........

form.addFormHandler(new FormHandler() {
public void onSubmit(FormSubmitEvent event) {
service.fileUpload(new AsyncCallback(){
public void onFailure(Throwable caught) {
Window.alert("FileUpload Failure!!");
}

public void onSuccess(Object result) {
Window.alert("FileUpload Success!!");
}});
event.setCancelled(true);
}

public void onSubmitComplete(FormSubmitCompleteEvent event) {
Window.alert(event.getResults());
}
});

RootPanel.get().add(form)

2. Servlet:: MyFormHandlerImpl

public class MyFormHandlerImpl extends RemoteServiceServlet implements MyFormHandler {

/**
*
*/
private static final long serialVersionUID = 1L;

@Override
public void fileUpload() {
System.out.println("0");
HttpServletRequest request = super.getThreadLocalRequest();
HttpServletResponse response = super.getThreadLocalResponse();

boolean isMultiPart =
FileUpload.isMultipartContent(request);//isMultipartContent(request)

String parentPath ="d:\\";

if (isMultiPart) {
System.out.println("3");
DiskFileUpload upload = new DiskFileUpload();
try {
List items = upload.parseRequest(request);
Iterator it = items.iterator();
while (it.hasNext()) {
FileItem item = (FileItem) it.next();
if(!item.isFormField()){
File fullFile = new File(item.getName());
File savedFile = new File(parentPath,fullFile.getName());
item.write(savedFile);
}
}
} catch (FileUploadException fUE) {
System.out.println("file not found");
} catch (Exception e){
System.out.println("unknown exception");
}
}

}
}

--------------------------------------------------------------------
Can anybody tell me what i am missing here?
what could be done to resolve this error?

Thanks in advance for your help.

Arun.

I'm sorry, but general GWT questions should be directed to Google's GWT forum.

Thus forum is for GWT Designer related questions only.
