RewriteRUle只对图片起作用但是对JSP不作用这是怎么回事呢

我设置了一个RewriteRule 规则，

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^(.*)/unicom/fun/([0-9]+)/(.*)$ $1/unicom/f/$3
RewriteRule ^(.*)/unicom/fee12/([0-9]+)/(.*)$ $1/unicom/f/$3
RewriteRule ^(.*)/uni/20/([0-9]+)/(.*)$ $1/wap20/new/$3
RewriteRule ^(.*)/confirm20/([0-9]+)/(.*)$ $1/wap20/new/$3
RewriteRule ^(.*)/fee20/([0-9]+)/(.*)$ $1/wap20/new/$3
RewriteRule ^(.*)/cu/20/([0-9]+)/(.*)$ $1/wap20/new/$3
</IfModule>


但是只对图片起作用对程序却无效，这是怎么回事呢，
