Easiest way to enable Google authentication for GWT application? (non-GAE-hosted)

由 谁都会走 提交于 2020-01-02 06:19:16
问题 What is the easiest way to enable existent GWT application authenticate users using Google account? I tried googling (lol) it but have found no solutions that could work out of the box. Is there a library to solve this problem in like 10 lines of code? P.S. The application I've mentioned isn't hosted at Google Apps if it matters. 回答1: I have been looking at gwt-oauth2 for this purpose recently. It looks pretty decent, and the docs are straightforward. Perhaps it could be of interest. 来源：

由 烈酒焚心 提交于 2020-01-02 05:59:29

GWT : fileUpload.getFileName() & fakepath

由 拥有回忆 提交于 2020-01-02 05:13:12
问题 I am working on a GWT project (web application) : at some point, users can upload a file through the application via a FormPanel. As I need the filename, I thought I could use : FileUpload upload = new FileUpload(); // ... String name = upload.getFileName(); And name turns out to be something like this : C:\fakepath\whatever.txt . Is this cross-platform ? What happens on other OS (I am using Windows) ? 回答1: The name returned by a upload form is dependent on the browser's security settings. On

Access web service from GWT

由 自作多情 提交于 2020-01-02 04:47:11
问题 Is there any way how I can access a web service from GWT using its WSDL? Previously I was trying to use the generated classes from ws-import.... but then someone pointed out to me that GWT cannot handle all Java, just a subset of it, hence it won't understand the ws-import classes. Thanks and regards, Krt_Malta 回答1: GWT can access web services using a RequestBuilder, which makes HTTP calls to a service and then gets access to its response. Since your web service is using SOAP, the response

Which doctype should I use for GWT 2.0?

由 ∥☆過路亽．° 提交于 2020-01-02 03:37:11
问题 I think I should use <!DOCTYPE html> for my new GWT application; I understand that doing so will put my application into standards-compliant mode. Am I correct? Are there any disadvantages to using this doctype? Does GWT work properly in standards-compliant mode? I'm wary because the GWT tutorial still uses the HTML 4.01 transitional doctype. 回答1: The new layout panel functionality in GWT 2.0 requires standards mode and does not work in quirks mode. 回答2: Using <!DOCTYPE html> will put the web
