I'll use spring mvc and hibernate. When i start server, "org.hibernate.HibernateException: Could not obtain transaction-synchronized Session for current thread" error is occurs. So, I search what's the problem. I find serveral things. one is use 

<tx:annotation-driven transaction-manager="transactionManager" />.

and I added. but, "The prefix "tx" for element "tx:annotation-driven" is not bound." error occurs. So, i search answer again and get answer and then apply it. That is using xmlns:tx="http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd". But, - cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'tx:annotation- driven'. and Unable to locate Spring NamespaceHandler for element 'tx:annotation-driven' of schema namespace 'http:// www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd' error is occurs. When i search answer, it is recursively repeated. How can I solve this problem? help me...

It is my servlet-context.xml.

You miss

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

in your beans declaration.

<?xml version="1.0" encoding="UTF-8"?> <beans:beans xmlns="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:beans="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd 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/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd">

Your declaration is wrong. Defining a namespace and schema location are 2 different things. Don't put xmlns:tx inside the xis:schemaLocation that should be http:.

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

In short remove xmlns:tx=" from the xsi:schemaLocation.

Another tip use the versionless schema instead of a versioned one.

There was an additional " in the schema location fixed it. Also make sure you are removing the right one!!!
