Jpivot中MDX编辑器中文乱码问题解决方案
使用Jpivot中的MDX编辑器时，当MDX语句中出现中文时，点击应用后把MDX语句中的所有中文变成乱码，出现这样的问题在WCF文档中有解决方案；
可以参考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现了问题，这里更正为:
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中这里写错了，要支持中文大部分都是用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><!--我过滤的所有jsp文件，你可以过滤具体的页面或文件夹-->
</filter-mapping>
问题的解决方案就是把上述过滤器添加到web.xml中
