The prefix “tx” for element “tx:advice” is not bound

Error:
The prefix “tx” for element “tx:advice” is not bound

Story:
I was updating my code, to add in DB data insertion into 1 of my action class.
hit the above error “The prefix “tx” for element “tx:advice” is not bound”
From the error message, i think its complaining the missing of to define the schema location.
So, I add the schema location, and restart the tomcat…. eh, same error again?!
OK, i did a google and found out that, I not only missed to define the schema location;
I also forget to defind the “tx” header. (something like “tablib” in jsp).
So, I add in the following line “xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance” and test again.
Wow, its working now!

Lessons Learned:
The root cause of this error is missing the “xmlns:tx” being defined in applicationContext.xml

Solution:
Final applicationContext.xml header:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:jee="http://www.springframework.org/schema/jee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:aop="http://www.springframework.org/schema/aop"
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
