[wp-xmlrpc] XML RPC no response with flash lite?

[M.S.]

hi everyone, this is my first post

i'm trying to develop flash lite client for wordpress blog, i've tried  
using xmlrpcflash by mattism @ sf.net but when put into mobile it  
gives out of memory error.

so i'm trying to re-write at first the metaWeblog.getRecentPosts but  
unsuccessful, hope i can get a solution. i haven't done programming  
for 8 years so i'm in beginner mode.

the xml is created as xml rpc spec but i got no XML response back. any  
idea why?

this is the trace output in flash (username and password replaced):

this is xmlcallstring:  
<methodCall><methodName>metaWeblog.getRecentPosts</ 
methodName><params><param><value><string>1</string></value></ 
param><param><value><string>username</string></value></ 
param><param><value><string>password</string></value></ 
param><param><value><int>20</int></value></param></params></methodCall>
