          我的評論

          re: jsp自定義錯誤頁 和田雨 2007-07-29 10:32  
          在開始動手之前,我一般習慣整體盤算一遍,這樣感覺下起手來,比較順. 只是有時盤算的過于細致,往往會被某個小細節拖住步子. 所以這個時候,老大總會叫我move on,先把架子搭起來,如果什么都考慮,那么永遠也無法前進.
          做了一些東西之后,真的發現這個理想中成立實際中困難的理論. 設想,最好把目光放在方向上.
          先感嘆一下.

          404錯誤頁出現這個問題,我在web.xml定義了如下的定義,
          <error-page>
          <error-code>404</error-code>
          <location>/error_404.htm</location>
          </error-page>
          路徑的是對的,奇怪的是我測試時輸入一個不存在的頁,出現404錯誤提示出現的卻不是我所定義的頁面,這就怪了.我記得在weblogic中我也是這樣定義的,所以我首先想到的時服務器的問題. 只是這種問題,不要分析,我試著在javaworld發了一貼,問了一下. 二樓給了一個鏈接, 我進去才發現這個問題已經有很多人在討論了.這是實際出問題,要是一直照著課本,應該不會想到這些問題,只是自己實際操作的才發現這些.

          通看了所有的帖子,出現這種問題,主要有以下幾個因素:
          1.使用 tomcat 服務器
          2.tomcat服務器版本
          3.瀏覽器問題
          4.IE的設置
          5.錯誤頁本身的大小

          第一點,我想我的經歷應該可以算個證明.

          第二點.很多人用tomcat5.5可以順利的找到錯誤頁

          第三點.換了一下FF,可以順利找到指定的錯誤頁

          第四點.我設置了 工具-->Internet選項-->高級--->顯示http友好錯誤信息(取消選擇) ,可以順利定向到指定錯誤頁,
          說明可以

          第五點,我試著發狠輸了一大堆東西進去, 指定錯誤頁順利出現了.


          下面是提供的解決方法:

          1.升級tomcat (換成其它服務器,代價沉重)
          2.ie 設定 工具-->Internet選項-->高級--->顯示http友好錯誤信息(取消選擇) ,
          3. 把錯誤頁做大一點,具體幾個字節,沒測試,估計三四百足夠了, (加一個div塊,display設為none就可以了)
          4.設置指定錯誤頁頁狀態為正確,騙過IE的自定義錯誤頁 方法
          <%
          response.setStatus(200); // 200 = HttpServletResponse.SC_OK
          %>

          re: FSO是什么及其開啟方法 和田雨 2007-07-23 16:18  
          前段時間困擾我的問題,終于在自己的努力下解決了,不敢獨享,先與大家分享.

          操作時出現 Server 對象 錯誤 'ASP 0177 : 800401f3' Server.CreateObject 失敗的解決方法

          一、系統沒有開啟FSO組件

          系統沒有開啟FSO組件.
          FSO組件的開啟和關閉方法
          Dll 文件的注冊和注銷:
          在開始菜單運行
          注消FSO組件:RegSvr32 /u %windir%\SYSTEM32\scrrun.dll
          啟用FSO命令:RegSvr32 %windir%\SYSTEM32\scrrun.dll

          二、多次注消、啟動后還是出現錯誤,原因是沒權限,不知道怎么造成的,下邊提供解決方法

          權限出現了問題,打開注冊表加入權限!
          在 開始-運行中敲入regedit,然后找到HKEY_CLASSES_ROOT\Scripting.FileSystemObject

          右擊權限,加入everyone,internet來賓帳號(IUSR...)用戶確定,然后重新啟動IIs即可搞定!

          This is the XML Schema for the Servlet 2.4 deployment descriptor.
          The deployment descriptor must be named "WEB-INF/web.xml" in the
          web application's war file. All Servlet deployment descriptors
          must indicate the web application schema by using the J2EE
          namespace:

          http://java.sun.com/xml/ns/j2ee

          and by indicating the version of the schema by
          using the version element as shown below:

          <web-app xmlns="http://java.sun.com/xml/ns/j2ee"" target="_new">http://java.sun.com/xml/ns/j2ee"

          version="2.4">
          ...
          </web-app>

          The instance documents may indicate the published version of
          the schema using the xsi:schemaLocation attribute for J2EE
          namespace with the following location:

Absolute filenames (i.e., those starting with "/") also specify names in the root of the JAR file's namespace. In general, relative names are preferred.

Because of that, the multiplicity of the elements of distributable, session-config, welcome-file-list, jsp-config, login-config, and locale-encoding-mapping-list was changed from "?" to "*" in this schema. However, the deployment descriptor instance file must not contain multiple elements of session-config, jsp-config, and login-config. When there are multiple elements of welcome-file-list or locale-encoding-mapping-list, the container must concatinate the element contents. The multiple occurance of the element distributable is redundant and the container treats that case exactly in the same way when there is only one distributable.</xsd:documentation>
