Eclipse cannot find javax.servlet.http.HttpServlet

I am using GWT with AppEngine on Eclipse. When I try to build a simple Servlet, Eclipse keeps complaining that javax.servlet.http.HttpServlet " cannot be found in source packages ".

How can I get Eclipse happy?

updated: found the problem: it seems Eclipse with the GWT pluging would rather have server-side code in a .server package.

确保gwt sdk中的gwt-user.jar在构建路径上。

您可以使用maven并向servlet-xxx jar(例如servlet-api-2.4.jar)添加依赖项。
