我程序中现在应用了这样的框架srping+struts2+hibernate，不知道struts-menu应该怎么配置，还有麻烦有经验的大哥给个例子，就是基于的角色的权限控制用struts-mune实现时的表结构，谢谢了！如果不用struts-menu有什么别的方案，主要是想不同权限的用户登录时所展示的页面不同（主要体现在导航树上）。

我想用HttpClient访问一个https网站，我已经拥有服务端证书和客户端证书，我将服务端证号和客户端证号都导入到jdk的cacerts中，也按着网上的办法： <br />httpclient完全支持ssl连接方式。通常，如果不需要进行客户端认证和服务器端认证的ssl连接，httpclient的处理方式是和http方式完全一样。 <br />现在这里是讲的是需要客户端认证数字证书时的httpclient处理方式（因为需要客户端认证时，连接会被主动关闭）。 <br />1。使用ie访问你要连结的url地址，这时你会看到弹出一个询问是否继续和服务器建立连接的对话框（安全警报）。选择“查看证书”->“详细信息”->“复制文件到”导出数字证书（例： server.cer或server.crt）。 <br />2。使用导出的数字证书来创建你的keystore <br />keytool -import -alias "my server cert" -file server.cer -keystore my.truststore <br />keytool -genkey -v -alias "my client key" -validity 365 -keystore my.keystore <br />3。在引入AuthSSLProtocolSocketFactory.java，AuthSSLX509TrustManager.java和AuthSSLInitializationError后在你的代码里按下面的例子里来进行ssl连接 <br />Protocol authhttps = new Protocol("https", <br />new AuthSSLProtocolSocketFactory( <br />new URL("file:my.keystore"), "mypassword", <br />new URL("file:my.truststore"), "mypassword"), 8443); <br />HttpClient client = new HttpClient(); <br />client.getHostConfiguration().setHost("sh.12530", 8443, authhttps); <br />/*只能使用相对路径*/ <br />GetMethod httpget = new GetMethod("/"); <br />client.executeMethod(httpget); <br /> <br />执行后报错： <br />javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure <br />我确认程序是已经找到服务端证书了，可能在客户端认证的时候出错了，请问我错在哪了，怎么办？

实体类代码如下： 
public class Organization {
	private int id;

	private String name;

	private String sn;
	
	private String description;
	
	private Organization parent;

	private Set children;
get和set省略

业务实现类： 
//删除机构
	public void delete(int orgId) {
	Organization org =(Organization)this.getHibernateTemplate().load(Organization.class, orgId);
	System.out.println(org.getChildren().size());
}

getchildren和getparent都无法读取，null

调用size导致空指针异常

当我调用不传数据时不报异常 可以调通 但是一旦放如数据就会报错!

系统的测试服务器是Linux + weblogic

myEclipse中用xFire开发webservice项目,开发完成后,配置完成后，成功部署在Tomcat下，运行Java客户端程序成功。
webservice中有传递数据类型为二进制流,在发布weblogic9测试的时候遇到很大问题,这种数据类型不支持.部署也没有什么问题,客户端如果不传递二进制流,服务可以调用成功, 加上二进制流数据后,weblogic出现异常如下:

我现在在用SVN+hudson ,我的SVN的服务器和客户端都在一台机器上，我的资源库的路径是E:\svn\repository。当我向资源库中导入项目时看不到此项目在资源库中的位置，但checkout时也确实有此项目导出来， <br />1 我的问题时，究竟这些项目在资源库的什么位置呢？ <br /> <br />然后在配置hudson时，我在新建项目里，有个SCM-Repository URL选项 <br />我填写的时svn://localhost/，但我在想，这个资源库里如果有很多项目，那么hudson <br />中的这个新建的项目是在持续集成那个项目呢？难道全部项目都在一起持续集成？肯定是不会了， <br /> <br />2 所以我的问题是：我怎样能指明是持续集成资源库里的哪个项目呢？是不是可以在Repository URL选项中这样写svn://localhost/project1（加入项目是叫project1），但因为我在资源库里找不到我导入的项目，所以我觉得这么写还是有问题的。如果你在这方面有经验，希望你能帮助我，非常感谢！

结果打印为1,而我已经在regex里的"."的"+"后面加上了"?",应该是Reluctant形式的。为什么还会取到1,而不是2. 

String content = "<td>1</td><td>2</td>abcd z";
String regex = "<td>(\\d{1,3})</td>[a-z ]+?z";
Pattern p = Pattern.compile(regex);
Matcher m = p.matcher(content);

上面这一段也能使打印2.但是我不明白的是为什么在".+"后面加?就不会使用最小匹配了呢?

小弟初學webservice
想知道 如果client傳來數個request
希望server端的記憶体內有共同的變數，可供每
request傳來時,經過運算之後，Response回去。
類似的情況，比如DtatBase裏有一萬筆紀錄，希望在
Server啟動時或第一次收到request時，將這一萬筆紀錄
載入到記憶体內，可供第2,3....個request來使用。
不希望一直重複的read db
這有點類似 網站的session的性質。
請各位先進指導一下嘿。謝謝

JSF好像除了dataTable标签外，没其它的用于循环显示数据的吧？


但是dataTable是循环行，也就是说竖着往下循环。


我现在是要横着循环显示一个List的数据，请问有什么办法解决？


我想使用JSTL循环，结果JSF的backBean不知如何创建在页面上，然后JSTL的EL表达式引用。


请教。。

问题补充：
能否提示更详细点？谢谢。

因为我要做一个类似报表编辑的功能，界面上要有坐标系，一系列点组成的折线或者曲线，这些点可以动态拖拽编辑。谁做过类似的，能共享下代码就更好了。

另外就是我的数据里面坐标都是小数点后有六位数据的浮点数，如何能够设计一种方法能把它无损的转换成-100-100之间的整数，而且当我在图形界面编辑了之后，还能在再把整数在无损的转换成我的数据的格式。

function generatePara(){
var a=10
}

如何将javascript中的变量值传递到rails代码中以便于使用？
怎么把a的值传到Controller？？ 

class LookController < ApplicationController
    def form
   @user = params[:a]
   end

end


请大家指教，谢啦！
问题补充：
我想用 prototypeHelper 里面的方法来解决在解决这个问题，有是办法马？
<%= link_to_remote
:url => {:action => "look"},
:updata => "";
:before => "generatePara()"
%>

怎么弄阿？
