this.username = username;
}
public String getDisplayValue() {
return displayValue;
}
public void setDisplayValue(String displayValue) {
this.displayValue = displayValue;
}
}
我的问题是:
将战争部署到tomcat6.0.29中之后，运行我的应用程序. 当我单击a4j:commandbutton时，发生以下错误
After deploy my war into my tomcat6.0.29, run my application. When i click the a4j:commandbutton the following error occur
HTTP Status 404 - /.jsp not found
type Status report
message /.jsp not found
description The requested resource (/.jsp not found) is not available.
Apache Tomcat/6.0.29
帮帮我. 预先感谢
推荐答案
操作的返回值用于查找要显示的新视图.通过在faces-config中找到一个匹配项，或者在其中没有映射，直接将其用作页面名称即可.当您返回一个空字符串时，最终仅以.jsp作为文件名.如果要返回同一页面，请返回null而不是空字符串.
The return value of your action is used to find the new view to display. Either by finding a match for it in faces-config or if there is no mapping there by using it directly as the name of the page. As you return an empty string you end up with only .jsp as the filename. If you want to go back to the same page return null instead of an empty string.
