I have competed the templated config files that exist in a new mvc spring project. I have done the same to the three files. In one I get the following error:

Referenced file contains errors (jar:file:/<path to STS>/sts-2.5.0.RELEASE/plugins/org.springframework.beans_3.0.5.RELEASE.jar!/org/springframework/beans/factory/xml/spring-beans-3.0.xsd). on the header of the beans declaration. I have done exactly the same to the three file. Why this one does bring up an error. The header is:

<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"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schem...ng-aop-2.0.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schem...-beans-3.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schem...ontext-3.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">

Do I miss something? Do I do something wrong?

Thanks for your help.
