How show Chinese an Japanese fonts

I develop some engine for generating reports in pdf format. Client
gets through http protocol into Browser. Adobe Acrobat reader is
launched by Browser.

I use xsl:fo from that.
The result  is processed by apache FOP serializer included into Apache Cocoon.

I should provide national localization.

With most languages I have no problem.
I just include to pdf embeded fonts.

But not for Chinese and Japanese.

Adobe provide Open fonts from
http://www.adobe.com/products/acrobat/acrrasianfontpack.html
but them doesn't work with my result pdf stream even in both case:
1) I don't include  embeded fonts to stream 
2) I don't include  embeded fonts to stream and write name of font
"Adobe Ming Std Acro L" to fo:block/@font-family
Can anyone to help?
