A question of URL rewrite

Hi,

I hope to rewrite sin.jsp?code=111&x=2 to sin/111.htm
I tried the two ways below but it is still failed. Please help me out.
Thanks very much!

rewrite “^/sin.jsp?code=([0-9]+)&x=([0-9]+)$” /sin/$1.htm last;

rewrite “^/sin.jsp?code=([0-9]+)&x=([0-9]+)$” /sin/$1.htm last;
