My project: GWT 2.3.0, GXT 2.2.5 Server: Glassfish 4.1. IDE: NetBeans 8.0.1 with plugin gwt4nb.
I try create simply GXT project but when i run application it give me page with only label and button looks like html. If i want add slider or other component - browser doesnt display this (I think code wasn't compile to html, css etc).
step by step what i done
1.Create new project: web application and technology: gwt
2. Add library to classpath gxt.jar
3. Add resources from gxt.rar to war folder in my project
4. Add <inherits name='com.extjs.gxt.ui.GXT'>
to Main.gwt.xml
5. Add <link rel="stylesheet" type="text/css" href="resources/css/gxt-all.css" />
to html
I think the problem is your gwt apps can't load the gxt-all.css. This is one of many ways to include the gxt-all.css file :
Clean your workspace, and restart you gwt application, and you should be good now. Hope this helps. Thanks
