Answer 1

I was getting the same error. The cause was the missing Maven dependency spring -webmvc. I included the below dependency and it started working.

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>${spring.version}</version>
        </dependency>

I have enroled for spring course on udemy. I followed every step that my instructor show me to do. So if you are using spring mvc and hibernate you may encounter this error Failed to read schema document 'http://www.springframework.org/schema/tx/spring-tx.xsd' etc for:

<mvc:annotation-driven/> and <tx:annotation-driven transaction-manager="myTransactionManager" /> elements

in my spring configuration file i had these two urls

    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

in xsi:schemaLocation, which i replaced with

    http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd

    http://www.springframework.org/schema/tx 
    http://www.springframework.org/schema/tx/spring-tx-4.2.xsd

actually i visited these two sites http://www.springframework.org/schema/mvc/ and http://www.springframework.org/schema/tx/ and just added the latest version of spring-mvc and spring-tx i.e, spring-mvc-4.2.xsd and spring-tx-4.2.xsd

So, in my opinion specifying version no explicitly is a good practice. It worked for me, hope this works for you too. Thank you.

Answer 3

In your spring context xml mvc namespace url should match url in schemaLocation. Something like this:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="
         http://www.springframework.org/schema/mvc
         http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

This is a standard XML namespace declaration. The namespace url is sort of an unique id, which is then mapped to the actual schema location in xsi:schemaLocation.

Answer 4

When using Spring namespaces urls I normally do not use version information and that works most of the time pretty well. You might like to try the namespace url

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

instead of

http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd

Answer 5

I think your schemaLocation mapping is incorrect. The namespace is specified as:

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

which is correct, I believe, but in the schemaLocation you have

http://www.springframework.org/schema/mvc/spring-mvc
                http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd

So if you change the first line of the schemaLocation mapping to your mvc namespace, it should work fine.
