Make sure, following jar file included in your class path and lib folder.

spring-core-3.0.5.RELEASE.jar

enter image description here

if you are using maven, make sure you have included dependency for spring-core-3xxxxx.jar file

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

Note : Replace ${org.springframework.version} with version number.

org.springframework.core.io.Resource is part of spring-core-<version>.jar

But this lib is already in your lib folder. So I guess it is just a Deployment Problem. -- Try to clean your server and redeploy your application.

Right-Click on your project -> Properties -> Deployment Assembly.

On the Left-hand panel Click 'Add' and add the 'Project and External Dependencies'.

'Project and External Dependencies' will have all the spring related jars deployed along with your application

There is a version conflict between jar/dependency please check all version of spring is same. if you use maven remove version of dependency and use Spring.io dependency.it handle version conflict. Add this in your pom

 <dependency>
            <groupId>io.spring.platform</groupId>
            <artifactId>platform-bom</artifactId>
            <version>2.0.1.RELEASE</version>
            <type>pom</type>
            <scope>import</scope>
  </dependency>
