I want to add this code in /usr/share/tomcat7/conf/context.xml :

```
<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
   sticky="true"
   memcachedNodes="n1:<%= node['redis']['host']%>:<%= node['redis']['port']%>"
   requestUriIgnorePattern=".*.(ico|png|gif|jpg|css|js)$"
/>

```

I'm using Chef 11.4, I've created custom cookbook and modify /opsworks\_java/templates/default/webapp\_context.xml.erb

But it doesnt work.
It worked for other file: server.xml!

How can i do that?

thanks.
