Unable to locate NamespaceHandler for namespace ('context')

I am fighting with this issue for a few days now and I am really desperate. Legacy project that I am upgrading from gives me the following error message during Tomcat startup:

Configuration problem: Unable to locate NamespaceHandler for namespace
[http://www.springframework.org/schema/context]

Why cannot it process the context schema?

Some background information:

There are a lot of questions about this issue, most of them due to the fact that corresponding JAR is not in the class path. Not in my case. The application is packaged as war and placed into Tomcat's webapp folder. During startup the war is being unpacked by Tomcat into own folder, where WEB-INF/lib folder contains "spring-context-3.2.1.RELEASE.jar" file.

Log files are attached to to the end of this question. Pay attention that tomcat cries about Setting property 'cacheAllowed' to 'false' did not find a matching property. during startup. It seems like it does not load the org.apache.catalina.core.StandardContext. My context.xml file contains the following:

<Context cacheAllowed="false" crossContext="true" debug="0"
    docBase="${project.build.finalName}.war" path="/lup-web" privileged="true"
    reloadable="true">
</Context>

The offending file (services.xml) starts with the following:

<?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:context="http://www.springframework.org/schema/context"
       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">

    <context:component-scan base-package="com.mycompany.lup.pages"/>
    <context:component-scan base-package="com.mycompany.lup.messages"/>
    <context:component-scan base-package="com.mycompany.lup.importData"/>
    <context:component-scan base-package="com.mycompany.lup.servlet"/>

    <bean class="com.mycompany.lup.importData.ConversionService">

Long story short... It was another issue with invalid dependency. Spring 2.0 jar was somewhere on the CLASSPATH.
