Jpivot中MDX編輯器中文亂碼問題解決方案

使用Jpivot中的MDX編輯器時，當MDX語句中出現中文時，點擊應用後把MDX語句中的所有中文變成亂碼，出現這樣的問題在WCF文檔中有解決方案；
可以參考wcf中的api：
Package com.tonbeller.wcf.charset Description
Forces the request encoding to UTF-8 or another configurable character encoding.

Problem: in servlet 2.3, when ServletResponse#setLocale(java.util.Locale) is called, the character encoding is changed implicit in an unspecified way. To prevent this, this wrapper does not forward the setLocale call. All JSTL fmt:xxx actions call setLocale on the response, which causes the problem.

This package uses a response wrapper that does not allow the character encoding to be changed. Also the filter sets the Request encoding to UTF-8 (or another configurable charset) because most browsers dont follow the http spec and do not send a content-type header when submitting a form. They use the character encoding of the page that contained the form.

The encoding is configurable as filter init parameter encoding, via the property tbeller.charset. If the filter is installed, it defaults to UTF-8, otherwise it defaults to ISO-8859-1.

The filter automatically changes (or adds) the response encoding of one configurable content-type. If the filter init-param contentType is set to text/html, then a response content type will of "text/html; charset=iso-8859-1" will be changed into "text/html; charset=utf-8".

The ContentTypeTag sets the content-type and character encoding of the response to the given type.
但是它使用的例子出現了問題，這裡更正為:
Filter example:
  <filter>
    <filter-name>CharsetFilter</filter-name>
    <filter-class>com.tonbeller.wcf.charset.CharsetFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value><!--api中這裡寫錯了，要支援中文大部分都是用UTF-8，-->
      <description>character encoding that this filter will enforce</description>
    </init-param>
    <init-param>
      <param-name>contentType</param-name>
      <param-value>text/html</param-value>
      <description>this content type will be set to the above encoding automatically, e.g. "text/html; charset=iso-8859-1" will become "text/html; charset=utf-8"</description>
    </init-param>
  </filter>
  <filter-mapping>
 <filter-name>CharsetFilter</filter-name>
   <url-pattern>*.jsp</url-pattern><!--我過濾的所有jsp檔案，你可以過濾具體的頁面或檔案夾-->
  </filter-mapping>

問題的解決方案就是把上述過濾器添加到web.xml中
