Google spell check service example problem !

Hi!

I have installed wso2 wsf/php as the Installing and Running on Linux Guide says.

Here are my php.ini settings for wsf/php :

include_path = ".:/usr/share/php:/usr/local/wso2:/home/e1n"

[wsf]
extension=wsf.so
wsf.home="/usr/local/wso2"
wsf.log_level = 3

I was trying to run google spell check service example.
But problem occured:

I have passed valid google key ,etc.

Any suggestions ?

The compilation process ran smoothly, every thing seems to be all right , but i can't track this problem.
