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。。

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。

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？

最近碰到个很诡异的问题。请问可不可以将一个List转成ResultSet。
将List转成CachedRowSet。因为CachedRowSet继承了ResultSet这个类。代码如下：
Iterator it = wkKeyList.iterator();
while(it.hasNext()){
cachedRowSet.moveToInsertRow();
cachedRowSet.updateString(1, (String)it.next());
cachedRowSet.insertRow();
cachedRowSet.moveToCurrentRow();
cachedRowSet.afterLast();
}
不知道这样可不可以。请达人予以帮助。多谢多谢。

我猜既然单元测试调用发邮件没有问题，那么部署后有问题，是不是与部署的环境有关系？？？？

在AppFuse官方文档 http://appfuse.org/display/APF/Using+Hibernate 中给出了创建一个新model的实例。 <br />文档称要建立一个model 名为Person，需要建立相应的 PersonDao接口和PersonDaoHibernate实现。 <br /> <br />PersonDao 接口定义了方法public List<Person> findByLastName(String lastName); <br />PersonDaoHibernate 继承了 GenericDaoHibernate，并实现了PersonDao 接口： <br /> public List<Person> findByLastName(String lastName) { <br /> return getHibernateTemplate().find("from Person where lastName=?", lastName); <br /> } <br /> <br />为何不直接使用 PersonDaoHibernate ，而要多建一个 PersonDao 接口呢？ <br />难道每建一个 model 都要建立相应的3个类吗？太麻烦了。<br/><strong>问题补充</strong><br/>整明白了，谢谢各位，我想AppFuse这样做，一是代码生成使用<br />mvn appfuse:gen 能够自动化；一是可以转换Dao的实现。比如：<br />PersonDaoHibernate如果用着不爽要， 可以使用PersonDaoiBatis。<br /><br />再问一下,如果我现在有了model类Person，eclipse自己能否重构出<br />PersonDao,PersonDaoImpl,PersonService,PersonServiceImpl？<br />如果能的话，怎么做？
