J2EE、WEBGIS项目开发 Tapestry、Prado、Zend框架学习

原来原因在这里：
css文件里font-family: "黑体";这句导致后面的css定义全部不起作用了。
只要把font-family: "黑体";
改成
font-family:黑体;
就行了，去掉空格和双引号。
这个问题只存在于IE6中。
 

    由于服务器上之前已安装Confluence, 它已自带了tomcat1.5。
而我想在服务器上再启用tomcat1.6，发布我的包。我用的是解压版。
在网上看了很多改端口的设置，在server.xml中将所有端口+1后，运行startup.bat，发现启动的还是tomcat1.5。
于是我修改了startup.bat，终于成功启动tomcat1.6了，以下红色标注的是修改的地方：

在Eclipse下打开Window-preference，点击ant,钩中 create problem markers from "javac" results

在bulid.xml中配置红色属性就行了。

如：
public abstract void setModifyItem(String item);
 public abstract String getModifyItem();

public void saveAndSubmit(){
  saveEach();
  setModifyItem("");
  refreshDetailItem();
 }

<span jwcid="@If" condition="ognl:modifyItem">
    .......
</span>
    <span jwcid="@Else" >
    ...........
</span>

在listener中将modifyItem设为空字符串后，页面显示的还是@If下的内容，而不是@Else后的内容，这是为什么呢？

在本机调试程序时，有时会出现这个错误，重新启动服务就好了，但不知为什么会出现这样的问题，不知道项目正式上线使用的时候会不会出现这样的问题。

这是正常的显示效果：<input jwcid="@Submit" listener="listener:deleteUser" parameters="ognl:components.table.tableRow.id" value="删除"/>
这是不正常的显示效果：<input jwcid="@Submit" listener="listener:khDetail" parameters="ognl:components.toDoTable.tableRow" value="去评 "/>

真是好奇怪哦！在.html中都是用的@Submit啊！

.java文件中：
public void pageBeginRender(PageEvent event) {
  if (getUser()==null) {
   getRequestCycle().activate("Home");
  }
  //if (!getRequestCycle().isRewinding()){    ！！如果这行不注释掉，就会出现这个错误，注释掉这行就可以正常运行，是为什么啊？
   List<KhItem> itemList=getKhImpl().getKhTodo(getUser().getUserID());
   for(int i=0;i<itemList.size();i++)
    itemList.get(i).setOrderNum(i+1);
   setTodoList(itemList);
  //}
 }

在.page文件中；
<property name="todoList" />
<component id="toDoTable" type="contrib:Table">
  <binding name="source" value="todoList"/>
  <binding name="columns" value="literal:orderNum,khCategaryName,khBegintime,khEndtime,employeeName,todo"/>
  <binding name="pageSize" value="30"/>
  <binding name="tableSessionStateManager"
   value="new org.apache.tapestry.contrib.table.model.common.FullTableSessionStateManager()"/>
 </component>

在.html文件中：
<table class="ForrestTable" cellspacing="1" cellpadding="4" jwcid="toDoTable">
   <tr><th></th><th></th><th></th><th></th><th></th><th></th></tr>
   <tr >
   <td></td>
   <td></td>
   <td></td>
   <td></td>
   <td></td>
   <td jwcid="todoColumnValue@Block" >
    <input jwcid="@Submit" listener="listener:khDetail" parameters="ognl:components.toDoTable.tableRow" value="去评 "/>
   </td>
   </tr>
   </table>

错误：

org.apache.hivemind.ApplicationRuntimeException
