Re: How to upload a file using GWT ?

2009-02-11 Thread ender 

Hi,

I've finally figured it out.
In order to link the form with the servlet, you have to map the
servlet in web.xml. It is similar to writnig the struts-config.xml
file.

After putting the servlet info there, you just need to pass the
servlet url in the form action, and on submit you will end up with the
execution of the servlet.

 //... code
 FileUpload fileUpload = new FileUpload();
 fileUpload.setName(file);
 fileUpload.setTitle(File);
 fileUpload.setVisible(true);
 fileUpload.setSize(330 , auto);

 //this is added in the FormPanel later

 formPanel = new FormPanel();   // the formPanel contains an UploadFile
 which
 formPanel.setEncoding(multipart/form-data);
 formPanel.setMethod(FormPanel.METHOD_POST);
 downloadButton.addListener(Events.Select, new Listener() {
                         public void handleEvent(BaseEvent be) {
                                 submitForm();
                                 //validForSubmit = true;
                         }
                 });

 private void submitForm() {
         ImpexDefinitionMgrAsync impMgr =  ImpexDefinitionMgrAsync)
 SafirWebUI.getServiceForEntity(ImpexDefinition.class.getName());
        impMgr.importFile(fileUpload.getFilename(),
 this.parentGridPanel.getClassName(), new MaskAsyncCallback() {
             @Override
                         public void onSuccessInternal(Object result) {
                                 //Long id = ((ImpexDefinition) 
 result).getId();
                                 //importDetailId.setValue(id != null ? 
 id.toString() : null );
                                 formPanel.setAction(ServiceLocator.server_URL 
 + reports/upload);
                                 formPanel.submit();
                         }
         });
         }

 // end of code

 This way I can only transfer to the server side the file path but this
 is wrong because the only place where it shall work is on the
 localhost, otherwise on another server, it will crash, because the
 file will not be found. I thought either I read the file and send its
 content, or I send the whole file (and this is the best approach but I
 don't know how to do it, since GWT doesn't know java.io).

 Hope you will have an idea...
