security.xml strange error using Spring

Question

Answer 1

You're declaring the namespace as b: and using it everywhere except the enclosing beans tag, in which you're using beans:beans instead of b:beans.

You're missing up the beans and b prefixes. You've declared the b prefix, and then used the beans one. You need to pick one and stick with it. For example, replace

xmlns:b="http://www.springframework.org/schema/beans" 

with

xmlns:beans="http://www.springframework.org/schema/beans" 

and then

<b:bean...

with

<beans:bean...
