Install Coldfusion 11 on IIS 7 and see error 404.0 when I try to run servlet

I install Coldfusion 11 on IIS 7 and see error 404.0 when try to run servlet from "index.cfm". I added:

    .class in folder C:\ColdFusion11\wwwroot\WEB-INF\classes,

    servlets configuration in C:\ColdFusion11\wwwroot\WEB-INF\web.xml,

    .jar in C:\ColdFusion11\wwwroot\WEB-INF\lib,

    "index.cfm" in C:\inetpub\wwwroot,

Servlets are java classes. "index.cfm" is run, because it located in IIS home folder(C:\inetpub\wwwroot) and when I try to go to servlet from "index.cfm" i see error 404.0. Before I work on Coldfusion 9 and it's work perfectly, but I will need to use websockets and Coldfusion 9 not support its. In Coldfusion 9, when I install it, I check "Configure web server for Coldfusion 9 applications" if see "Error 404" and it's solve problem. In 11 version I not see checkbox "Configure web server for Coldfusion 11 applications". Maybe in this is my problem. Please help!
