[spring] The matching wildcard is strict, but no declaration can be found for element 'tx:annotation-driven'

One extra forward slash (/) in front of tx and the *.xml file troubled me for 8 hours!!

My mistake:

http://www.springframework.org/schema/tx/ http://www.springframework.org/schema/tx/spring-tx-4.3.xsd

Correction:

http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd

Indeed one character less/more manages to keep programmers busy for hours!
