我已经将RichFaces演示逐字放在了index.jsp页面中。由于演示没有提供任何支持此源代码的支持bean代码,因此我在panelMenu.java中创建了这些方法
public void updateCurrent(String n) {
logger.info("updateCurrent called with " + n);
setCurrent(n);
}
public String getCurrent() {
return current;
}
public void setCurrent(String c) {
curr

如何在Andro JSP上配置Jetty应用程序以接受JSP?
我有一个Spring4.0.9MVC应用程序,使用JSP作为视图技术,使用Maven 3.2.5进行构建管理。我使用Eclipse4.4.1进行开发,使用Tomcat 7.0.57运行应用程序。
在JSP中,我希望使用EL表达式${pageContext.request.contextPath}来引用当前请求路径。但是Eclipse给了我一个错误:
javax.servlet.jsp.JspException cannot be resolved to a type
我添加了以下Maven依赖项:
<dependency>
<groupId>javax.servle
我尝试在不使用位置设置的情况下连接位置服务,但每当我运行该项目时,它都会给出错误。我提到了下面的代码
public class Practice2 extends Activity implements LocationListener{
private static final String TAG = "Profile";
protected static final int REQUEST_CHECK_SETTINGS = 0x1;
protected LocationManager locationManager;
protected LocationListene
我有一个包含用户的列表。我正试着用JSP打印它,但有些地方我无法让它打印出来。获取此异常HTTP Status 500 - javax.servlet.ServletException: javax.servlet.jsp.JspTagException: Neither BindingResult nor plain target object for bean name 'users[0]' available as request attribute
JSP中的代码
<c:forEach items="${users}" var="user&
onUnload: function () {
let onMessageReceived = function(res){
console.log(res,'取消监听')
}
let onSdkReady = function(res){
console.log(res,'取消监听')
}
tim.off(TIM.EVENT.SDK_READY, onSdkReady);
tim.off(TIM.EVENT.MESSAGE_RECEIVED, onMessageReceived)

我在web -INF下的网页下添加了这个shir.ini:
[main]
# Objects and their properties are defined here,
# Such as the securityManager, Realms and anything
# else needed to build the SecurityManager
shiro.loginUrl = /index.jsp
[users]
root = 12345,admin
guest = 12345,guest
[roles]
admin = *
[urls]
