Spring security filter blocking restful api calls

I have a web application using Spring 4. I'm using Spring security here. In the mean time I need to open a restful api with no security. Issue is till the security filter is enabled my rest rest POST calls get a 405 Method Not Allowed response(Still the GET works). When I comment the security filter from the web.xml POST works fine. I tried adding following line to security xml but didn't help.

<intercept-url pattern="/rest**" access="permitAll" />

My web.xml , security filter is and the end which when commented POST start working.
