J2EE、WEBGIS項目開發 Tapestry、Prado、Zend框架學習

原來原因在這里：
css文件里font-family: "黑體";這句導致后面的css定義全部不起作用了。
只要把font-family: "黑體";
改成
font-family:黑體;
就行了，去掉空格和雙引號。
這個問題只存在于IE6中。
 

    由于服務器上之前已安裝Confluence, 它已自帶了tomcat1.5。
而我想在服務器上再啟用tomcat1.6，發布我的包。我用的是解壓版。
在網上看了很多改端口的設置，在server.xml中將所有端口+1后，運行startup.bat，發現啟動的還是tomcat1.5。
于是我修改了startup.bat，終于成功啟動tomcat1.6了，以下紅色標注的是修改的地方：

在Eclipse下打開Window-preference，點擊ant,鉤中 create problem markers from "javac" results

在bulid.xml中配置紅色屬性就行了。

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中將modifyItem設為空字符串后，頁面顯示的還是@If下的內容，而不是@Else后的內容，這是為什么呢？

在本機調試程序時，有時會出現這個錯誤，重新啟動服務就好了，但不知為什么會出現這樣的問題，不知道項目正式上線使用的時候會不會出現這樣的問題。

這是正常的顯示效果：<input jwcid="@Submit" listener="listener:deleteUser" parameters="ognl:components.table.tableRow.id" value="刪除"/>
這是不正常的顯示效果：<input jwcid="@Submit" listener="listener:khDetail" parameters="ognl:components.toDoTable.tableRow" value="去評 "/>

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()){    ！！如果這行不注釋掉，就會出現這個錯誤，注釋掉這行就可以正常運行，是為什么啊？
   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="去評 "/>
   </td>
   </tr>
   </table>

錯誤：

org.apache.hivemind.ApplicationRuntimeException

Either the tableModel parameter or both source and columns parameters must be specified by component Role/toDoTable.tableView

    新年到了，找了個新家，希望能在這里認識眾多的鄰居，還望各位鄰居們能多多指點哦！
    在這里向各位鄰居們，還有物業管理的工作者們拜個新年了！！！祝大家在新的一年里一直牛！！！！
