    dc.add(Restrictions.eq("purePeptide", purePeptide));
    dc.add(Restrictions.eq("project.id", projectId));
    dc.addOrder(Order.asc("peptide"));

    dc.add(Restrictions.eq("p.purePeptide", purePeptide));
    dc.add(Restrictions.eq("project.id", projectId));

两段代码唯一的区别就是第二句是使用"purePeptide"还是"p.purePeptide"。
代码一产生的sql语句：
select this_.purePeptide as y1_, this_.peptide as y2_ from SequestPeptide this_ where y1_ = 'NASILLEELDLEK' and this_.project_id=1 order by y2_ asc
运行会报Unknown column name:Y1_

代码二产生的正确的sql语句：
select this_.purePeptide as y1_, this_.peptide as y2_ from SequestPeptide this_ where this_.purePeptide='NASILLEELDLEK' and this_.project_id=1 order by y2_ asc

这里，experimenters是projectForm的属性，类型为String[]
msms_experimenterlist是保存在request中的一个set<UserInfo>，email是UserInfo的属性，类型为String。

显示以及传递到/projectUpdate.do对应的Action都正常，但是如果给projectForm的experimenters设置了初始值，在真实显示的时候，多选框中并没有设置这些初始值，很是麻烦。

虽然最后通过jsp的方法解决，总是不爽阿：

       <%ProjectForm projForm = (ProjectForm) request.getAttribute("projectForm");
         HashSet<String> oldExperimenters = new HashSet<String>(Arrays.asList(projForm.getExperimenters()));
         List userList = (List)request.getAttribute("msms_experimenterlist");
         for(int i = 0;i < userList.size();i++){
           UserInfo user = (UserInfo) userList.get(i);
           if (oldExperimenters.contains(user.getEmail())){
             out.print("<option value=\"" + user.getEmail() + "\" selected>" + user.getEmail());

首先通过调用shutdown.bat，而且不设置spawn="true"，这样就会有一个cmd窗口在那里留着，可以看着tomcat停掉了，然后关 闭这个cmd窗口，ant才会继续向下执行删除和拷贝，然后自动启动tomcat。虽然看上去比较怪，好歹还算管用，哈哈。

后来在hibernate网站上(http://www.hibernate.org/6.html)看到：

Fixing Ant classpath/plugin issues

You may need to add junit.jar to your $ANT_HOME/lib directory if it is not there already, or alternatively remove the $ANT_HOME/lib/ant-junit.jar file. For Hibernate3, repeat the steps above, but also copy lib/antlr.jar or remove the $ANT_HOME/lib/ant-antlr.jar file.

These steps are necessary because Ant ships with plugin stub libraries in its classpath, so Ant plugins for JUnit or Antlr can't be used without copying or removing files. If you don't have Ant installed on your machine or don't want to mess with the default Ant installation then, on Windows, just run build.bat to use the bundled Ant libraries.

虽然他说可以用build.bat来进行，但我也不知道他为什么会找不到javac，反正我把antlr.jar拷到ant的lib下面，就OK了。

    </target>


这里跟昨天的代码有一点不一样：
1、localWar改成了war。
原来更新远程服务器的时候，总是显示更新成功，但是到webapps目录下总是没有相应的war文件，通过调用
ant list-web
发现，有一个context-path是dist/msms，而且是stop状态。哦，原来localWar的意思不是指开发的机器的local path，而是指把这个war被写到服务器的什么地方。改成war就正常了。

2、不需要判断是否已经deploy进而调用undeploy了，直接通过update="true"更新就可以了。

遇到一个怪问题，百思不得其解：
通过ant depoly可以把msms.war部署到tomcat上。当然，要求这时候webapps下面没有msms目录。
看tomcat的纪录，加载msms.war正常，网页也可以打开。

通过ant undeploy，可以把msms卸载。Tomcat显示：
Undeploying context [/msms]
正常卸载了。问题是，去看webapps目录下面，居然有一个msms目录的残骸，里面保留的目录是
WEB-INF\lib
有以下几个文件残留着：
commons-digester.jar
commons-validator.jar
struts.jar

这时候msms目录也无法手工删除，必须停掉tomcat后才能删除。

我装的tomcat是5.5。不知道是否还有人遇到过这种情况，我反正是晕了。

build.properties文件如下：
tomcat.dir=C:/ApacheGroup/Tomcat5.5
tomcat.webapps=C:/ApacheGroup/Tomcat5.5/webapps
tomcat.manager.url=http://localhost:8080/manager
tomcat.manager.username=admin
tomcat.manager.password=xxxxxxxx

BeanFactory factory = new XmlBeanFactory(new FileInputStream("hello.xml"));
应该是：
BeanFactory factory = new XmlBeanFactory(new FileSystemResource("hello.xml"));

2、KnightApp
在实现了XML中Minstrel的interceptor后，
需要把
KnightOfTheRoundTable knight = (KnightOfTheRoundTable) factory.getBean("knight");
改成：
Knight knight = (Knight) factory.getBean("knight");
否则会报：
Exception in thread "main" java.lang.ClassCastException: $Proxy0

2、在hibernate.cfg.xml中增加：
<property name="hibernate.proxool.pool_alias">dbpool</property>
<property name="hibernate.proxool.xml">proxool.xml</property>
<property name="connection.provider_class">org.hibernate.connection.ProxoolConnectionProvider</property>

3、在与hibernate.cfg.xml同级目录（src根目录下）增加proxool.xml文件：
<?xml version="1.0" encoding="utf-8"?>
<!-- the proxool configuration can be embedded within your own application's.
    Anything outside the "proxool" tag is ignored. -->
<something-else-entirely>
    <proxool>
        <alias>dbpool</alias>
        <!--proxool只能管理由自己产生的连接-->
        <driver-url>
            jdbc:mysql://localhost:3306/msms
        </driver-url>
        <driver-class>com.mysql.jdbc.Driver</driver-class>
        <driver-properties>
            <property name="user" value="sqh" />
            <property name="password" value="sqh" />
        </driver-properties>
        <!-- proxool自动侦察各个连接状态的时间间隔(毫秒),侦察到空闲的连接就马上回收,超时的销毁-->
        <house-keeping-sleep-time>90000</house-keeping-sleep-time>
        <!-- 最少保持的空闲连接数-->
        <prototype-count>5</prototype-count>
        <!-- 允许最大连接数,超过了这个连接，再有请求时，就排在队列中等候，最大的等待请求数由maximum-new-connections决定-->
        <maximum-connection-count>100</maximum-connection-count>
        <!-- 最小连接数-->
        <minimum-connection-count>10</minimum-connection-count>
    </proxool>
</something-else-entirely>

4、重起tomcat

后面加上：    
    session.flush();
    session.clear();
这后面再查询，就没有问题了。一个简单的解决办法吧，对效率的影响有多少就不知道了。

昨 天新安装Tomcat 5.5，把msms从原来的Tomcat 5.0的webapps拷到5.5下面，运行出错。是intenal error。检查了所有需要的包都在，数据库连接也正常，hibernate没问题，难道是Struts出错了？网上找了好多资料，最后看到一篇文章说， 可能是在WEB-INF/lib下面多了与Tomcat不兼容的jsp-api.jar和servlet-api.jar。想到为了使Eclipse编译 所需要的jar都在一起，把Tomcat5.0的两个jar放到了WEB-INF/lib下，估计就是这个问题了。删除后，重起Tomcat，OK。
