OK, say I have test project com.willow.sandbox.Sandbox.gwt.xml I run project in hosted mode and URL in the hosted mode browser when I run it is:
http://localhost:8888/com.willow.sandbox.SandBox/SandBox.html I manually put an image in c:\....\src\com\willow\sandbox\public\images \star.gif I display this image in panel like so in my test GWT application: someWidget.add(new Image(images/star.gif); I run application again and It works fine. Now, still in same hosted mode session, I select "compile/browse". This displays my application in my system default browser, but as part of that process it also compiles all the javascirpt, HTML files etc and sets up the public folder - including my image, start.gif This also works, so I close this browser tab for now. I know open new browser tab and enter this URL (but I do *not* stop the hosted mode run - this won't work if you do that because the GWT hosted mode Tomcat will be also stopped): http://localhost:8888/com.willow.sandbox.SandBox/images/star.gif So my system browser finds and displays the star.gif image no problem! If you follow these steps (using your own paths for the URL of course), since we have already proved that the new image file has been correctly saved (because String[] photoList = photo.list(); picked it up), then you should be able to display the new image in your system browser, thus proving beyond reasonable doubt it is really there. That will further isolate your problem to either some error in your client side code (however unlikely that may seem since it works when you reboot), or something weird going on with browser caching. regards gregor On Jan 21, 5:27 pm, Daniele <[email protected]> wrote: > I don't understand.. > > 2009/1/20, gregor <[email protected]>: > > > > > There's something weird about this.
