1. 在GWT的JAVA代码里取得Context Path //若生成的JS所在目录为war/moduleName path = GWT.getModuleBaseURL().replace("/" + GWT.getModuleName(),""); //若生成的JS所在目录为war/gwt/moduleName path = GWT.getModuleBaseURL().replace("/gwt" + "/" + GWT.getModuleName(), ""); 2.在module xml里引用context path下的css文件时，用“..”来代表上级目录 <stylesheet src="../stylesheet/xxx.css" />
用dev mode 以debug的方式启动程序，然后在 entry point处设断点，最后访问使用了这个module的页面，但Eclipse却不会在预期的地方断开，为什么？ 一般来说这都是因为你的页面里所引用的js文件并没有指向dev mode编译出的文件所在的目录。 dev mode编译出的文件都放在 war/moduleName下，你的HTML里是不是把 moduleName.nocache.js 的路径写错了？
