I'm getting the error above on my "tx:annotation-driven" line, but I've declared the namespace at the top of the beans file, why is the following XML causing this error? 

    <?xml version="1.0" encoding="UTF-8"?>

Just like your other xmlns: definations, you need one for xmlns:tx

xmlns:tx="http://www.springframework.org/schema/tx"
  • awesome - thanks, this is a bit bizarre but after adding this, now none of my MVC @requestmapping in my controllers work and my application just 404's as the dispatcherservlet says it can't map anything. Do you have any ideas? – David Apr 29 '12 at 15:16
  • I don't know spring webframework well, but most probably because I don't think having xmlns:tx is the source of your problems.
    May be you forgot to include the spring transactions + AOP libraries in your WAR.     –  Apr 29 '12 at 16:29

You may look here for further information:

The tx tags deal with configuring all of those beans in Spring's comprehensive support for transactions. These tags are covered in the chapter entitled Chapter 9, Transaction management.

...

In the interest of completeness, to use the tags in the tx schema, you need to have the following preamble at the top of your Spring XML configuration file; the emboldened text in the following snippet references the correct schema so that the tags in the tx namespace are available to you.

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd">

   <!-- <bean> definitions goes here -->

</beans>

You must introduce the annotation tx to your project, you must install them, dont use the xmlns, it doesn't work correcty, I see that you develop with annotation, its good practice and use this,

http://www.springframework.org/schema/tx

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

For the former solution doesn't help try this put it at the top make sure that you do not forget any xsi:schemaLocation.

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="
    http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context.xsd
    http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc.xsd
    http://www.springframework.org/schema/tx 
    http://www.springframework.org/schema/tx/spring-tx.xsd"></beans>

You can use these :

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:context="http://www.springframework.org/schema/context"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="
    http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context.xsd
    http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc.xsd
    http://www.springframework.org/schema/tx 
    http://www.springframework.org/schema/tx/spring-tx.xsd">
