 <s:label label="中文名" value="${artistVO.chineseName}"/>

我要在页面输出"中文名"的时候,做一个判断,就是中文名不是 "无"或"缺" 的时候再输出.
用<s:if test="">该怎么写?
structs2文档里有一段关于<s:if test="">的例子

<s:if test="'foo' in {'foo','bar'}">
   muhahaha
</s:if>
于是我照葫芦画瓢
 <s:if test="${'artistVO.chineseName' not in {'null','','无','缺','未知'}}">
 <s:label label="中文名" value="${artistVO.chineseName}"/>
</s:if>

没有中文的时候还都正确,遇到中文的时候就不对了.这难道是中文问题吗?

/**

 public List getProducts(final int pageSize, final int startRow) throws HibernateException { 
     return this.getHibernateTemplate().executeFind(new HibernateCallback(){

         public Object doInHibernate(Session session) throws HibernateException, SQLException {
        
             Query query=session.createQuery("FROM Products as p");
             query.setMaxResults(pageSize);
             query.setFirstResult(startRow);

运行时怎么老给出异常阿？请帮帮我看看好吗？

]]>使用ant调用java类http://www.blogjava.net/samshi/archive/2007/01/24/95737.htmlsamfreesamfreeWed, 24 Jan 2007 06:57:00 GMThttp://www.blogjava.net/samshi/archive/2007/01/24/95737.htmlhttp://www.blogjava.net/samshi/comments/95737.htmlhttp://www.blogjava.net/samshi/archive/2007/01/24/95737.html#Feedback0http://www.blogjava.net/samshi/comments/commentRss/95737.htmlhttp://www.blogjava.net/samshi/services/trackbacks/95737.html最近使用ant时,遇到了一个小难题,在一个名为冰浪的blog的提示下解决了.现在把它贴出来.
首先判断cvs下有没有tag文件,如果有,就copy到当前目录,如果没有就调用java类创建,并写入当前
日期,然后在copy
<condition property="exist.tag"> 
    <and> 
        <available file="Tag" filepath="CVS/"/> 
    </and>
</condition>
<target name="copytag" if="exist.tag"> 
    <copy file="CVS/Tag" todir="temp"/>
</target>
<target name="createtag" unless="exist.tag" depends="copytag"> 
    <java classname="com.xxx.pub.Tag">
        <classpath>
              <pathelement location="${build}"/>          
         </classpath>
    </java>
 <copy file="Tag" todir="temp" failonerror="false"/>
</target>

]]>一个关于时间间隔的问题，请大侠们帮一下忙了。急！！！http://www.blogjava.net/samshi/archive/2007/01/04/91812.htmlsamfreesamfreeThu, 04 Jan 2007 09:58:00 GMThttp://www.blogjava.net/samshi/archive/2007/01/04/91812.htmlhttp://www.blogjava.net/samshi/comments/91812.htmlhttp://www.blogjava.net/samshi/archive/2007/01/04/91812.html#Feedback3http://www.blogjava.net/samshi/comments/commentRss/91812.htmlhttp://www.blogjava.net/samshi/services/trackbacks/91812.html我现在做一个socket客户端的接口，有这么一个问题。
1，如果在30秒内接收到服务器端返回的消息，就认为是一次成功的连接。否则断开此次连接
2，采用短连接方式。即每次往服务器端发消息都建立一次连接
3，每个发送请求最多允许3次连接。
问题：怎样判断30秒内没有接收到消息和收到消息时没有超出30秒就断开连接呢？
        请给小弟一个思路吧。
