我是新手,所以,抱歉,如果我错了.
我在Ubuntu 11.10下使用Struts2 + Spring和Hibernate框架在NetBeans中创建了一个项目.第一次运行是好的,但是当我第二次或第三次运行它时,我一直得到这个例外.没有Maven一切顺利.我安装了Maven的apt-get install,是的,我加入这一行export MAVEN_OPTS=-Xmx512m的usr/bin/mvn,但没有运气.如何从中获得更好的表现？
我是SSL的新手,尝试在Tomcat中启用它,但是在访问https:// localhost:8443 /时,我有firefox出现的错误:
An error occurred during a connection to localhost:8443.
SSL received a record that exceeded the maximum permissible length.
(Error code: ssl_error_rx_record_too_long)

Tomcat server.xml:
<Connector …以编程方式可以知道何时从Java中取消部署/停止使用Web应用程序？我需要停止一些进程运行,但是没有设置Tomcat,只需要Java代码？
几天前,当我打开电脑时,我尝试启动tomcat,并且自从我处理软件开发以来第一次出人意料.
确切的错误消息是:

Error occurred during initialization of VM

而且我无法理解它,也没有在谷歌中找到任何关于此的信息,尝试使用3种不同版本的tomcat 7.0.8,8.0.5,8.0.9,所有情况都是一样的.当我看到这个时,我认为JDK已经过时,因为我有几个版本,然后我从PC中删除了所有JDK和JRE,只安装了最后一个8u45,但没有任何运气.有人能指出我正确的方向吗？

我将石英库从版本1.5.2更改为2.1.2.使用它的旧版本,项目运行并且工作正常,但是在2.1.2中我得到了异常:

<bean id="lcJobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="lcTask" />
<property …所以我想假设我有一个字符串
"param1=value1¶m2={"url":"http://somesite.com?someparam=somevalue&someparam1=somevalue1"}¶m3=value3"
我需要它:
param1: value1
param2: {"url":"http://somesite.com?someparam=somevalue&someparam1=somevalue1"}
param3: value3
在Java中解析这个问题的最佳方法是什么？到目前为止,我找不到标准Java库的解决方案,我不想重新发明轮子.
我已经尝试过(但是如果我只在那里放置查询参数,那就不行了):
String url = "http://www.example.com/something.html?one=11111&two=22222&three=33333";
List<NameValuePair> params = URLEncodedUtils.parse(new URI(url), "UTF-8");
for (NameValuePair param : params) {
System.out.println(param.getName() + " : " + param.getValue());
}
我的Struts2有问题,在我的ActionClass中我声明了一个:
private Integer table; + setter and getter methods
然后我在.jsp中有一个表单:
<s:form action="add-note" theme="simple">
<s:select name="table" list="tablesList.{tableNr}" cssClass="tables" headerValue="-- Select table --" headerKey="-1"/>
</s:form>
但是当我尝试提交此表单时,我得到一个非常奇怪的例外:

我偶然发现了一个问题.我正在使用一个用jQuery编写的简单AJAX脚本,我想用AJAX回调来改变html with easeInOut效果,但是我不知道怎么做,因为现在,当响应来了,div的内容改变了有某种闪烁效果,这是非常难看的,我认为这是默认的"效果".
脚本:(我试图添加.fadeOut('slow')到html()方法,但没有改变)
$.ajax({
type: "POST",
url: "institutions-filter.action",
data: data,
cache: false,
success: function(result){
$("#display-block").html(result);
}
});
哪个 PHP 函数适合转义 HTML 以便在 中使用<iframe srcdoc="???">？
我找到了两个候选人：htmlspecialchars()和htmlentities()。应该使用哪一个来正确转义任何可能的 HTML 代码？
我有一个Struts2应用程序,我使用Tiles.如何在动作映射中获得多个结果类型？因为我需要将de输出设置为JSON数据,并将Tiles同时设置.我试过了:
<action
name="home"
class="com.deveto.struts.actions.HomeAction" >
<result name="success" type="tiles,json">tiles.home</result>
</action>
但这不起作用
