问题 I'm writing a selenium test for a GWT app. It uses the mouseover/ mousedown/mouseup approach to click pushbuttons. It clicks the Login button of my app, which calls up the div containing userid and password entry fields, and that works just fine. It then enters a userid and password, then clicks the Submit button for the login form. If I run it slowly, I can see the button click, but the request never gets sent to the server (I'm watching the wire). In fact, if, while the selenium IDE is

问题 I have a composite which extends ResizeComposite and has a DockLayoutPanel as its root. I can stick it directly into RootLayoutPanel and it works because DockLayoutPanel ProvidesResize . However, I'm wanting to use the MVP facilities in GWT 2.2, and RootLayoutPanel can't be passed to ActivityManager#setDiplay(AcceptsOneWidget) (since it's a multi-widget container).

问题 I've worked with GWT and eclipse for a while now and I wanted to play a bit with maven and the GWT plugin (gwt-maven-plugin, enter link description here). I tried to use it out of eclipse (Luna 4.4), but obviously I didn't do it correctly, as it was extremely brittle to the point that it broke on a regular basis as the IDE overwrote it's settings when I changed something small in the pom.xml. So I decided to take a step back and eliminate the black magic that eclipse is and start a new

问题 I am using HttpURLConnection to post to a REST API. I still have not successfully posted anything, so I'm trying to get back the XML response that should be coming from the API.

问题 In Google's RequestFactory tutorials, they recommend putting my persistence logic (in my case, Hibernate) inside the Entity classes. Then they pose the question: "What if you don't want to implement persistence code in an entity itself?" and proceed to explain an alternate method.

Any info is appreciated, thanks. -tjw 回答1: Putting the persistence code in an
