我遇到了下一个问题:我正在尝试通过startup.bat手动启动Tomcat,但似乎没有显示任何结果,然后我尝试运行shutdown.bat并且控制台显示下一个:

 D:\apache-tomcat-7.0.35\bin>startup.bat

Invalid initial heap size: -Xms256m -Xmx512m -XX:MaxPermSize=256m
Could not create the Java virtual machine.

catalina.bat是原创的,我也检查了所有的pathes和opts(即JAVA_HOME,JRE_HOME,CATALINA_BASE,CATALINA_HOME,CATALINA_TMPDIR).tomcat版本是7.0.35 java v 1.6

我写了下一个代码:

public void delete(MyType instance) {
        List<MyType> myList = this.getAll();

        Cookie[] cookies = request.getCookies();
        List<Cookie> cookieList = new ArrayList<Cookie>();
        cookieList = Arrays.asList(cookies);
        for(Cookie cookie:cookieList) {
            if(Long.valueOf(cookie.getValue()) == instance.getId()) {
                cookieList.remove(cookie);
            }
        }
        myList.remove(instance);
        cookies = (Cookie[]) cookieList.toArray();
}

问题是下一个:当我从cookielist中删除cookie时,我如何将更新的cookielist(没有删除的cookie)放回客户端？请求或响应没有任何*.setCookies();方法.或cookie会自动更新？最好的祝福.

当我尝试启动我的应用程序时,控制台显示下一个堆栈跟踪:

java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener

我已经阅读了同样的问题,但是没有spring-web jar,但是在我的pom.xml中我已经包含了spring依赖项,问题仍然存在:

         <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>

            <artifactId>spring-webmvc</artifactId>
            <version>${spring.version}</version>
        </dependency>

这是web.xml文件(只是为了确定):

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            classpath:/context/webContext.xml

我干净..,干净的tomcat工作目录......,我用项目清理工作区 - >干净..但没有任何帮助..我在这样的绝望...

更新=============经过一些操作和魔术:)我成功没有这样的异常,但下一个出现:

java.lang.ClassCastException: org.springframework.web.filter.DelegatingFilterProxy cannot be cast to javax.servlet.Filter

在实施jasig-CAS时我遇到了下一个问题:我想实现注销.目前它工作正常,但我希望CAS服务器在注销到请求来自的服务器后重定向用户(例如,http://localhost:8080/myApp).我试图在安全上下文中添加"服务",但这里没有发生任何事情是我的春季安全上下文:

<security:logout logout-url="/logout"
                        logout-success-url="https://localhost:9543/cas-server-webapp-3.4.10/logout?service=http://localhost:8080/myApp" 
                        invalidate-session="true" />

所有配置和程序均取自本手册.

我有以下问题:当我在模型中放入一些数据时,我想在视图部分检查一些复选框,它们等于我对象中的字段名称.这是HTML代码:

<div class="myDiv">
    <div class="divClass">
           <input type="checkbox" name="someData" value="0" id="id1">
        <label for="id1">Field1</label>
    </div>
    <div class="divClass">
        <input type="checkbox" name="someData" value="1" id="id2">
        <label for="id2">Field2</label>
    </div>
    <div class="divClass">
        <input type="checkbox" name="someData" value="2" id="id3">
            <label for="id3">Field3</label>
    </div>
    <div class="divClass">
        <input type="checkbox" name="someData" value="3" id="id4">
        <label for="id4">Field4</label>
    </div>
</div>

这里是jstl pseudo_code,我想获得:

<c:forEach var="field" items="${list.fields}">
    <c:if test="${field.name=='FIELD(1-4)'}">CHECK_THE_APPROPRIATE_CHECKBOX
    </c:if>
</c:forEach>
