我刚刚读过类似的帖子。我已经改正了我的错误。但不起作用...
我正在使用 eclipse + weblogic 进行编程。
我想我也没有解释。
我需要它有效。谢谢。

最佳答案
<h:commandButton type="submit" value="Ir a pagina 2" action="IndexToPagina2" >
看来您正在使用 JSF。您需要导入所需的标签库。
示例:
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
